In Febuary, Jim Owens - Caterpillar’s head man, spoke about Pres-ident Obama’s stimu-lus package, in which Owens described his firm as a ‘bellwether’ company. I can’t pre-tend that I, nor any-body else on this desk, knew what that meant,

so we dusted off the dictionary and discovered that the term derived from the mediaeval practice of plac-ing a bell around the neck of a castrated ram (the ‘wether’) The animal would then lead a flock of sheep wherever it wanted to go and it’s movements could be anticipated by the ringing sound before it could be seen. Most often nowadays, according to our book, the term is used for describing events in the stock market, with the bellwether compa-ny being the one that leads the rest of the industry, either up or down.

As such, Caterpillar finds itself in an unenviable sit-uation of leading the US manufacturing industry down to where nobody else would want to follow. Perhaps it is unsurprising then, that Cat welcomed the presi-dent’s stimulus package, even going as far to say that they hoped to recall laid off workers at some point.

What has this got to do with the Middle East? Well, plenty. As the world’s key market for heavy machin-ery, the buying patterns here could be a ‘bellwether’ for the wider industry. It might be too early to talk of a recovery, but the pulse of the market will be checked at the forthcoming PMV show, to be held in Dammam, KSA between 8-10th of March. All of the leading companies will be represented, and con-ference topics will include how to survive the cur-rent situation and develop new products for the next decade.

Specialist firms will also be well represented, with various companies showing devices that can help their clients work more efficiently. Just about every nation on earth with an industrial base will be repre-sented, including the US, all of Europe, Japan and, of course, China.

How will the world’s money makers, analysts and forecasters view such an event? Well, we’ll just have to see how it plays in Peoria.

JOBS The number of official job losses in Dubai’s construction industry in the past three months has shot past the 3500 mark.

The figure covers official announcements only. The actual number of redundancies is believed to be substantially higher.

This number does not include job losses in directly related fields including PMV, though the demand for skilled trades, such as crane operators has dropped sharply. Arty Wartanian, general manager of Gallagher Int. crane hire said “There was strong demand [for such operators], but that’s all gone now there are cranes sitting idle.”

To date 3533 jobs in Dubai’s construction industry have been lost. The sector has been rocked by plummeting demand for real estate as investors the world over struggle

to raise the finance required for the purchase of property, due to the inability of banks to lend in the current financial climate.

Al Shafar General Contracting was among the worst affected, announcing the loss of up to 1000 jobs last December. Nakheel was also heavily hit with 500 official redundancies during the same month.

Consultant WS Atkins has trimmed its numbers by 210, while Dubai Labour Supply Company (Dulsco) let go of 800 workers in two batches.

ConstructionWeekOnline.com reported last week that up to 20,000 Indian construction workers have been bulk booked onto flights out of Dubai, either to return home on extended leave, or to be relocated to alternative projects in the Gulf.

ACCIDENT Safety body Build Safe UAE (BSU) has posted a safety alert bulletin about correct working practices, following a fatal incident involving a worker who became entangled in a cement mixer truck.

The accident happened when the victim, an unnamed tyre-fitter, was asked to clean inside the hopper of the truck-mounted machine, prior to loading the trial batch of concrete to be used later in the day. As he climbed the ladder to gain access to the hopper, the drum was still rotating. Although the worker was wearing a standard overall, the sleeves were quite a loose fit. His cuff became tangled between the rotating drum and the hopper and he was pulled towards moving blade inside the drum, causing terrible injuries. He was pronounced dead at the scene.

After logging the accident,

BSU reported that the root cause of this accident was a ‘failure of management’ with a statement in the list of causes citing ‘the fact that a tyre fitter had been told to work on the moving parts indicates a failure on the part of the management to ensure the work was done by a competent person’.

In addition to the root causes, BSU also published a list of remedial measures that have been recommended on all types of machinery used on that site. The list includes recommendations such as a full and suitable risk assessment must be carried out prior to all work on machinery, and that powered machinery must be isolated prior to being cleaned or maintained, while emergency kill switches should be clearly indicated.

Commenting on the bulletin,

Layoff fi gures continue to climb in Dubai

Skilled trades are less in demand, as the downturn continues in Dubai.

Warning issued after mixer truck fatalityBSU secretary Elias McGrath stressed that the chain of events were unusual, adding; “It just shows how entanglement can result in fatality. All it took was his loose clothing to be tangled in the machinery. With those overalls, you can’t just rip the clothing off as the material is incredibly strong. He added that the health and safety breaches must serve as a warning

to the industry. “The machine was operating when the incident happened, which is a huge failure in supervision. Machines [that are] running while trying to maintain or clean them is a huge no.”

“It just shows the breakdown in training, management and supervision which resulted in death. There was nothing right about this scenario” he said.

A mixer accident must serve as a warning to industry, according to safety experts.

New crane deal supports region’s ports

Firm celebrates deals amid slowdown.

3533Official number of job losses in Dubai’s con-

struction industry to date

DEALS As one Chinese crane manufacturer celebrates it’s sec-ond recent major deal in the region, some US $100 billion (AED367 billion) worth of new port developments in the Mid-dle East are reported to be under threat as trade volumes plummet because of the worsening eco-nomic crisis.

Shanghai-based ZPMC will supply cargo handling equipment to the port of Sohar in Oman, for use by Brazilian steel con-glomerate Vale in a deal estimat-ed to be worth around US $80 million. Meanwhile, the far east-ern company has already start-ed delivering around 170 items of machinery to Dubai-based DP World in a deal worth US $340 million, in line with port’s expan-sion plans, which seemed realis-tic in the early part of last year.

However, a swift slump in glo-bal cargo trade has left port opera-tors in the Middle East struggling with the dilemma of whether to build the extra capacity needed in the region, or whether to hold off until the downturn eases.

Although DP World will open

its second terminal at Jebel Ali by the end of this month, rais-ing the capacity to 14 million 20-foot equivalent units (TEUs), but could shelve its plans to build a third offshore terminal.

“The growth we can expect is a grey area, but the land has already been reclaimed for ter-minal three, and within the next month we should make a final decision,” said Anwar Wajdi, sen-ior vice-president for commer-cial and corporate strategy at DP World.

“We do not want to fall behind. Terminal three has not been for-gotten. We are developing four depots around Dubai to help clear the port and increase capacity, but if terminal three is really needed, we can expedite that capacity,” he

said.Speaking at MEED’s Middle

East Ports Development Confer-ence 2009, Wajdi said the com-pany was keeping a close eye on trends as they develop. “We do not want a huge terminal stand-ing there empty,” he said.

Speaking at the same confer-ence, shipping lines said there was a definite need for expan-sion in the region and urged port operators to begin con-struction immediately.

HYBRID Korean-multinational Doosan Infracore reported that it will start developing a hybrid excavator with enhanced energy efficiency and emissions drastically reduced.

The plan for the development of the new excavator model is part of a Korean government plan for investing in future technologies. The consortium of seven institutions both in and out of Korea led by Doosan Infracore is participating in the project, in which a total of 18 billion won will be invested.

The new model of hybrid excavator uses a diesel engine and can supplement the insufficient engine output at a time when it’s overloaded with the surplus power saved. The future-oriented excavator can go a long way in reduction of fuel consumption and emission gas (carbon dioxide down by 35%) as well as enhancement of energy efficiency.

The 22 ton-class excavator plans will focus on environmentally-friendliness and economic

Hybrid development at Doosan

New site vehicle tyre in region

NEWS IN BRIEF

ALL go upAt least one US-based crane operator continues to expand. ALL Carolina Crane & Equipment family. Part of the ALL Erection & Crane Rental Corp., ALL Carolina added the all-terrain GMK7550 from Grove, as well as the Liebherr LTM 1300-6.1 to its ever-growing fleet.

Seminar successA seminar entitled ‘Heavy Transport & Lifting’ was held by crane safety expert Richard Krabbendam in Singapore on February 20th. Topics included safe transport and ultra heavy lifting.

Cooper say Valla goodMobile crane company Valla have supplied some remote-controlled compact models to the UK’s Avon-Cooper tyres. The Valla 75E models reportedly offer a much increased operating envelope compared with the old-style forklifts previously used.

New tyre from Dumlop Dunlop has relaunched its PG75 tyre for recycling applications, after an eight-year absence. The new PG75 RCL has been specifically designed for the requirements of wheel loaders used in the recycling industry. It features a wide, deep, non-directional tread that Dunlop says results in a long service life, as well as extra protection against chunking, penetration and cuts from sharp objects.

Going Loko at Metso A new model for preliminary crushing has been introduced to Metso’s Lokotrack range of mobile crushers in the shape of the LT110C, which weighs in at 58 tonnes. In transport mode the new machine measures 15.6 m (51.2 ft) in length, 3 m (9.8 ft) in width.

TYRE A puncture-resistant tyre for site vehicles and 4x4s has been launched, The Wrangler AT/SA from Goodyear features two layers made with DuPont Kevlar, a material which is five times stronger than steel, and the firm’s patented ‘Durawall’ sidewall reinforcement that enhances cut resistance in the sidewalls.“Tyre safety, quality and performance are elements that are of high significance in driving, especially since tyres are the only parts of a vehicle that come in direct contact with the road. Be it on- or off-road, in traffic or high speed driving, and dry or wet conditions, the new Wrangler AT/SA from

Goodyear proves valuable to the extremely popular 4x4’s and SUV’s in the region,” said Octavian Velcan, General Manager of Goodyear Middle East and Africa.“We are confident that when the Goodyear Wrangler AT/SA is introduced in the region later this year it will become as popular as the vehicles they are mounted on” he added. The Wrangler AT/SA features two high-tensile steel belts to improve the tire’s strength and two layers which improve the tire’s resistance to punctures in the tread. According to the comapny, drivers can enjoy the added benefit of a smooth, quiet ride that comes from

efficiency. Its fuel efficiency will be improved by about 35% with a power conversion device that helps reuse the energy usually wasted when turning and operating various devices.

Dr. Kim Nak-in in charge of the project said, “Doosan Infracore will secure its position as the world’s top construction equipment manufacturer in the hybrid excavator market, which is expected to grow to 730 billion won per year by 2020. Our hybrid technology developed here will also be applied to wheel-loaders

and forklifts.” The consortium led by Doosan

Infracore will be comprised of Komotec (specializing in motors), ADT (a manufacturer of power and electronic core parts), Doosan Mottrol, LS Mtron, Seoul National University, Korea Institute of Machinery & Materials (KIMM) and the German RWTH Aachen University (specializing in pneumatic systems electronics) Doosan is best known internationally for its subsidiary brands, which include compact equipment maker Bobcat.

Kevlar, as this material helps to absorb road noise. The Kevlar layers act as a sound barrier, reducing noise for an especially quiet ride.The makers say that the tread block sequence and shifting of the Wrangler AT/SA also provides a quieter and more comfortable ride. The addition of a centre-line rib on larger sizes not only helps to improve on-road handling but is another contributor to tire noise reduction.The Wrangler AT/SA is available in a 4-rib design and in a 5-rib design for larger sizes. The Wrangler AT/SA 4-rib is available with 15 and 16 inch rim diameters. All sizes are available throughout the region.

New Doosan will run on multi-fuels. Diesel consumption will be cut by a third.

Is this the world’s most advanced earthmoving operation?Deep in the heart of South Afri-ca’s bushland, just south of the Zimbabwean border is an enor-mous hole in the ground. Dug from solid rock, it spans three kilometres across and descends more than 400 metres. This is the Venetia diamond mine, one of the biggest and most produc-tive diamond mines in the world. It currently moves about 60 mil-lion tonnes of rock per year, yield-ing 8.2 million carats of diamonds (approximate value: 650 million). And since its inception in 1992 it has been continually implement-ing, upgrading and fine-tuning the latest ideas in computerised earthmoving management. The result is a 24/7 operation that boasts one of the most technolog-ically advanced machine-health monitoring systems, one that has pushed up equipment availability to an incredible 98+ percent.

A specially built control room overlooks the massive opera-

tion. Here, huge flat screen mon-itors show pictograms of all the earthmoving machines current-ly in use. A colour coding sys-tem designates the status of each machine: for example, BLUE pic-tograms show trucks return-ing for a load, GREEN for fully loaded trucks, and RED for idle machines. An automatic alarm system flashes problems such as a machine that hasn’t moved for five minutes. “We can see at a glance where each machine is, but we also have two-way com-munications with the operators so we can, for example redirect pick-ups where necessary,” says Mike Laboscartni, control room super-visor. “In addition to this real-time monitoring the control room generates valuable data such as tonnes per machine, per hour and even per shift. So it’s also an

excellent tool to identify operator training needs.” Not surprising-ly, Venetia was the first ever dia-mond mine to achieve ISO 9002 quality management certification.

A total of 47 Caterpillar off-highway trucks are used to trans-port the excavated rock from the base of the open-cast mine, whilst another 45 Cat dozers, loaders, and excavators support the oper-ation. As with most quarrying operations, where all the plant and expertise remain in one place for several years, the Caterpil-lar dealer has been able to work extremely closely with the mine owners to constantly improve and perfect machine reliability and drive down the costs per tonne. In addition to a tailor-made MARC (Maintenance And Repair Con-tract), the local Caterpillar dealer, Barloworld, has placed a perma-

nent 87-strong team of site man-agers, supervisors and support staff to help maintain the high equipment availability. And every day representatives of that team meets with the mine’s owners, De Beers in this case, to discuss and plan machine and the best use of operators.

“There’s actually no formal contract in place,” says Brett Ste-vens, sales manager for Barlow-orld Equipment. “By focusing on condition monitoring, compo-nents are expected to last much longer and that substantially rais-es reliability targets. To this aim, we’ve deployed the latest service and maintenance systems such as ProductLink, S•O•S (Scheduled Oil Sampling), the AQUILA Drill System, CAES (the Computer Aided Earthmoving System), and MVRS (MineStar VIMS Remote

HAUL IT Big cats prowl dia-

System). All these advanced sys-tems help us to manage, predict and optimize the almost 100 Cat machines on site.” The result is that all this intensive technology has made the Venetia mine one of the largest mining technology sites in South Africa. So let’s take a closer look at those systems:

PRODUCT LINKProduct Link is Caterpillar’s pro-prietary telemetric monitoring system. Computers on-board each machine gather critical engine performance data and transmit it wirelessly via satellite to one of the Caterpillar network oper-ations centres. Here is it proc-essed, prioritised and uploaded to a password-protected web-based portal. Engineers and technicians can then access the vital informa-tion to plan preventative mainte-nance strategies.

S•O•S Scheduled Oil Sampling, or S•O•S for short, is a laborato-ry service that helps detect prob-lems before they become serious. Similar to a blood test that a med-ical doctors use, an oil sample is taken from a machine’s hydrau-lics and sent to a Caterpillar-cer-tified laboratory. Here trained engineers analyse the sample and diagnose any specific prob-lems. Too much silicon, for exam-ple, indicates dirt entry into the hydraulics. Too much sodium: water coolant entry.

AQUILAThe AQUILA Dragline System takes the guesswork out of drill-ing by accurately guiding the operator in the execution of drill patterns, reporting on individual machine and operator productivi-ty, and allowing remote, real-time supervision of drilling activity and blast planning from the office.

CAES The Computer Aided Earth-moving System (CAES) is an

advanced earthmoving tool that allows machine operators to achieve maximum landfill com-paction and desired grade/slope. It also conserves and ensures even distribution of valuable cov-er soil without the use of tradition-al survey stakes and crews. It uses GPS technology, machine-mount-ed components, a radio network, and office management software to deliver real-time elevation, compaction and grade control information to machine operators on an in-cab display. The Venetia diamond mine uses this system to monitor shelf levels within the mine and ensures that all access roads are safe.

MVRSMineStar is a comprehensive, integrated mining information system. Through a series of sub-systems for production reporting, truck assignment, health moni-toring and fleet analysis, Mine-Star links information gathered in the field to the office business enterprise systems.

CONTINUOUS IMPROVEMENTIt all adds up to a highly advanced and comprehensive machine-health monitoring system. For example, the MVRS alone reports an average of 23,000 machine-health events each month, which are prioritized by Barloworld’s data centre. “In addition to the advanced monitoring systems we also constantly implement new programmes, some of which we pilot ourselves,” says Brett. “For example, we recently introduced a ‘Kidney Looping System’ that cleans and filters the hydraulic oil on board a machine. This is pri-marily to save on oil and extend machine component life by reduc-ing the number of oil changes and contamination entry points. It also filters out any debris that in time would cause permanent component failure. In some cases we found that filtered oil of 4,000 hours was surprisingly cleaner

than brand new oil. We financed and ran the pilot system ourselves before sharing the results with De Beers. They were so impressed that they invested 100,000 in more Kidney Looping Systems. These now also significantly con-tribute to prolonging component life as well as saving huge quanti-ties of oil – up to 41,000 litres were saved in the first eight months.”

THE SMART PARTNERSHIPIt’s that type of ‘smart partnership’ that runs throughout the Venetia operation, as can be seen by the parts depot. Advanced manage-ment systems ensure that fast moving items do not stay on the shelf for more than seven days: it’s the perfect balance between ensured availability without hold-ing too much stock. Larger parts, such as engines are stored cen-trally in Johannesburg, which

makes them also available to oth-er Barloworld customers across the region.

Another powerful example of this smart, problem-solving part-nership is the increased life-times of the tyres used on the Cat earth-moving machines. “Three years ago we were getting an average of just two and a half thousand hours of service from our tyres,” says Johnny Veloza, operations manager at Venetia.

“Barloworld suggested that we install special analytical soft-ware in our trucks to monitor the various gradients, torsion stress-es and turning radiuses on our access roads. After a compre-hensive analysis several stretch-es of roads were redesigned and the machine operators were giv-en extra training. We now have an average of 6,500 hours of service life from our tyres.”

A newly delivered 250 t capacity Liebherr telescopic crane from Al Faris Equipment rentals is being used by the J.T. Metro J.V on the Dubai Metro’s Jumeirah Lake Towers Station in a 140t twin lift of the gantry footbridge.

The LTM1250-6.1 joins the Al Faris Equipment Rentals fleet, one of the largest in the Middle East with more than 250 mobile cranes and including 130 Lieb-herr models; all fitted with Liccon software ensuring lifts are made safely and economically.

Al Faris Equipment Rentals was formed in Dubai in 1992 to provide rental cranes and trans-port for the oil and gas industry later extending into oil refineries,

power plants and the construc-tion sector.

To date, Al Faris has taken delivery of 22 Liebherr mobile cranes this year and has a further 14 on order including its largest mobile crane, a Liebherr 1200 t capacity LTM11200-9.1.

Illustrated, the LTM1250-6.1 performs a twin lift of the 32m lg x 10m wide x 6m high steel gantry which, once fitted out will become the pedestrian bridge spanning the four lanes of the Sheik Zayed Road at Jumeirah Lakes Station.

Weighing 140t, the gantry was lifted and positioned on ‘stools’ alongside the Sheik Zayed Road for fitting out. Once completed,

the bridge will be finally posi-tioned in a hydraulic lift.

The Liebherr LTM 1250-6.1 mobile crane features a 15.5m – 72m telescopic boom and has a maximum lifting capacity of 250t at 3m radius. It also features a 108m maximum lifting height.

The six-axle mobile crane offers improved operating safety in the travel mode and has a top speed of 80km.

DUBAI METROOn track for operations to begin in 2009, the Dubai Metro is set to be one of the most advanced urban rail systems in the world; and the world’s longest fully auto-mated rail system.

The 52.1 Km (32.5 mile) Red Line will feature 29 stations and run from Jebel Ali to Rashidiya.

Groundworks were started in February 2006. In August a sec-ond line, the 17.6 Km Green Line was announced, intersecting the red line at two stations and run-ning from Al Ittihad Square to Rashidiya.

When fully operational, the Dubai Metro has been designed to carry approximately 1.2 mil-lion passengers on an average day and 355 million passengers annually.

Main contractor for the Dubai Metro are Mitsubishi Heavy Indus-tries, Obayashi Corp, Kajima Corp and Yapi Merkezi JV.

Drilling rates of up to 540 m/shift for dewatering wells in the sand are being achieved by con-tractors on the Dubai Waterfront project in Jebel Ali with Sandvik Ranger 780 Rock Pilot drill rigs and tools.

Two contractors are each using a Ranger 780 Rock Pilot and Sandvik rock tools to drill 6 m deep holes in compacted sand at 1 m spacing for a dewatering system; producing up to 90 holes each shift.

The Sandvik combination is achieving faster penetration rates than conventional auger drilling techniques.

According to Jukka Naapuri, General Manager, Sandvik Min-ing and Construction Middle East, the concept, although not

particularly new, has not been utilised too much in the UAE. “But,” he continues, “with the sharp increase in dewatering requirements on major projects, such as the Waterfront, two con-tractors recognised the potential and each took delivery of Ranger 780 Tophammer rigs.”

HYDRAULICS“Advances in Sandvik’s hydraulic control system over recent years have also been a factor in using this technique,” he added, contin-uing, “The system is able to sense strata changes when drilling and is able to react to different layers of sand and mud much faster.”

Operator Rodolfo Bumatay, with many years experience of Sandvik rigs and jumbos in Saudi

Dewater well drilling techniques using Sandvik Tophammer drill rigs on the Dubai Waterfront project are achieving faster penetration rates in sand than conventional methods – producing up to 90 holes per shift

Arabia, UAE and the Philippines was very surprised and doubting when he first saw the application.

“I was really surprised because Sandvik rigs are designed for drilling rock and even though this was compacted sand I had my doubts,” he explained.

“Similarly it is important to observe the flushing pressure to avoid jamming so drilling must be done in a controlled way.”

It is also important to ensure that no mud enters the dust col-lector. “I have no time for wash-ing out, only time for drilling. It is therefore important sometimes to work with the suction shut-down.”

Despite initial doubts Rodolfo is confident in the Sandvik’s per-formance and in achieving the high performance rates.

BUTTONSThe Ranger 780 Rock Pilot is fit-ted with 3.66 m long Sandvik T51 rods and 102 mm Retrac button bits. The bits feature a ballistic button design to provide fast pen-etration and better flushing.

Since the rigs’ delivery to site, the button bits have not worn out and are still in service after five months.

WATERFRONTThe Waterfront is considered to be the largest and most ambitious urban development project in the world. The coastal development includes the world’s largest mas-

ter-planned city; encompassing an area of 1.4 billion square feet – twice the size of Hong Kong Island.

Detailed design and planning for the first five phases have been completed and more than 20,000 workers and 3000 construction vehicles are on-site.

To date more than 80% of the mainland earthworks have been completed and more than 40 mil-lion cubic metres of land graded in a little over a year.

Approximately 30% of the first 4000 ha island has been reclaimed, with reclamation underway on other islands.

The amount of land being reclaimed monthly is 3.52 mil-lion cubic meters – enough to fill Wembley stadium three times.

Major civil works and infra-structure have started on the first phase Madinat Al Arab.

This includes construction of the 8 km long Palm Cove canal running parallel with the coast-line.

The Sandvik rigs are currently being used to prepare dewatering wells to allow construction of 3-4 m sewer pipeline.

The self-sustained city has two main components, the mainland covering a 13 km x 7.5 km area and the Waterfront Islands – a six island archipelago stretching 15 km into the Gulf and covering a combined area of 2300 hectares.

The city, on completion, will house 1.5 million people.

Bolton. Many Brit-ish expatriates will be familiar with the west Pennine town, and most would

agree that it has little in com-mon with the Emirates. Bolton is cold, wet and slightly quaint. The UAE for the greater part, is not. It is true that both plac-es have regions known as Dei-ra, but that for the most part is where similarities between the two conurbations finish.

So it might be a surprise to

some that the University of Bol-ton, established as a mechanics’ institute back in 1824, has recent-ly chosen to open a campus in Ras Al Kamiah. Zubair Hanslot, academic director, explained; “We decided about April last year that we needed to diversi-fy our student base so take our provision overseas. Although we were operating in many mar-kets like Vietnam and China and Malaysia we didn’t have a fully-fledged campus. All the opera-tions were small scale based on

one or two courses and one or two staff would fly over and do a delivery in a sort of intense block and then the students got some local support. We thought it was OK, but the market demands are slightly different now as we are going global. More and more people are saying why don’t you set up a campus where the whole provision is at the same place?”

“So last year, we decided we wanted a campus. We looked around and we thought there is a lot happening in the UAE, par-

ticularly in Dubai. It is the place where we could create a ‘hub’. We looked at Dubai, and at first we wanted to be in Academ-ic City, but when we investigat-ed, we thought that there were a lot of players there already. We thought the competition is quite fierce and that it is not a sustain-able market” he said. With rents fairly high, and many European colleges already based in Dubai, it was time for the University to consider some different options.

“We didn’t throw the towel in”

Hanslot explained, “Instead we looked at the free trade zone here in RAK, who were very support-ive. We did a marketing plan and we did negotiations with the free trade zone and found that there is a market. RAK isn’t that big and the rents are charged we could pass on the savings to make stu-dent fees quite reasonable.” This is true. With a year’s tuition cost-ing around the AED 24,000 mark, it is not cheap, but compares favo-rably to other Western colleges operating in the region.

He explained that the authori-ties, right to the highest level had been extremely accommodating in helping to untie the red tape associated with setting up in a new country. The university now had to consider what courses it was going to teach. Back in the UK, it is known for degrees in mechani-cal and construction engineering. Hanslot commented; “We’ve set up a number of courses including the MSc in Construction Man-agement which is a postgradu-ate course delivered on a part

time basis and we are targeting mainly working professionals. We are only interested in people who are working in the indus-try who have got some academ-ic (ability) as an undergraduate degree and what we are trying to do is upskill tham into how to be an effective manager in the con-struction industry. They have got the technical knowledge, which we are building on to give them some business and managerial knowledge to manage the con-struction industry.”

While students might already be qualified engineers, Hanslot argues that there is always the need for more study; “Training is necessary as there is always development in this industry. Engineering, as you know, never

stands still - we are always push-ing the envelope” he said, adding that these days computer mode-ling holds a place in the industry like it hasn’t done before. “There is a lot more done on a simula-tion basis where if you wanted to prove something you had to build a prototype in the laborato-ry and use final element analysis where you could model the struc-ture by using mathematical ele-ments in the piece of software.” He explained that although com-puters were used in complex projects, until quite recently they were complicated; “The advance-ment is very computer simulation led and because of that there is a lead time between the concept and actually proving the concept has shortened dramatically.”

This is all very well, but who is going to enroll on an expen-sive course during these difficult times? Hanslot remains upbeat. “A university always does well in a recession. People who are at risk of losing their jobs are always interested in retraining. We’ve seen an increase in people enquiring particularly for engi-neering type of programs because people see that they need to get themselves a good, stable sort of qualification to see through the recession and beyond we are recession proof in that regard” he said, and initial enrolment figures being around a third higher than predicted, seem to bear this out.

Perhaps north-west England and the Emirates are not so dif-ferent after all.

AUCTION YARD


Efficiency is the name of the game when it comes to selecting the right track-type trac-tor – or bulldozer, for

the task. Sometimes a small ‘dozer is

perfect for the job, for exam-ple when clearing scrub on a new roadbuilding project and the site manager has his eye on the amount of diesel consumed. However, when the dirt hits the shovel, it might be better to think outside the box shovel.

We’re not strangers to large bulldozers in the GCC, with colossal machines such as Cater-pillar D10 and D11 having been a regular introduction on major projects since their introduction back in the 1970s.

Less common are the Komat-su family of bulldozers. There

are some – about a dozen exam-ples of the 475a are currently grazing the site of the Arabian Canal for example.

However, it is the enormous D575a which really excels in size and power. With an operat-ing weight of 168 tonnes it is by quite some margin the largest bulldozer in production today. These V12-powered machines are most usually to be found in the word’s open cast mines, but today there is one sitting in the Jebel Ali freezone. Though the size of the blade depends on the specification ordered the one we saw measured more than 24 feet wide.

This particular example dat-ed from 1998 and came with full service records. As it was the slightly earlier D575a-2 model, it ‘only’ had an operating weight

of 140 tones, where as the lat-er D575a-3 model tips the scales at 168 tons. Another D575a-2, an earlier model from 1993, was also due to arrive.

There is no telling which part of the world will buy such a machine of course, although there is a good chance it might go to a local buyer. A high per-centage of machines do stay in the region, and even though the construction boom has cooled through much of the GCC, there are still many ongoing civil engi-neering projects like highways and junction improvements – just the sort of thing where the aptly-named ‘Super Dozer’ would come in handy.

Cat D10 hulked over smaller equipment. This particular mod-el had been specified with a four-shank ripper, rather than the more usual single shank com-mon in this region. When intro-duced, the original D10 was the first model in the Caterpillar line-up to introduce the trade-marked raised final drive. How-ever, these very large machines are still rare. Far more common is the 49 ton (operating weight) Cat D9. These machines are vary popular if in good condition, and frequently fetch a strong auction price. Eight models of varying ages and condition were entered into this sale.

Making up the total of 38 ‘doz-er were also 10 Cat D6 machines of varying types and ages, a selection of smaller Komat-su models and an open platfom 1993 Furukawa, which boasted a shiny new coat of paint.

Elsewhere in the auction yard there were a series of trucks of various types. First among them was a Mercedes 409 from the early 1980s. So far, so hum-

drum you might think, but this was a one-time fire engine, com-plete with German municipality logos and bright red paintwork. Unfortunately, much of the glo-ry had long since left this item, and we think it must have been many years since it last fought a real fire.

KENWORTHOf much more use to the PMV sector might be one of the Ken-worth C500 6x4 trucks that have been entered into the sale.

These bright orange or red machines became the tool of choice for the oil and gas sector, when the black gold was origi-nally struck in the region. With their go-anywhere ability and huge towing capacity, the trucks are still popular in the region now, and are often seen moving construction equipment around the Gulf. Specifications vary, but most feature a Detroit Diesel 8-cylinder engine, buttoned uphol-stery, power steering as well as enormous ‘nudge bars’ around the radiator grille.

EXCAVATORSThe region’s most popular exca-vator, being the Caterpillar 320, was also well represented with 11 lots consigned. More than half were 320b models from the late 1990s, though there were also the newer 320d models on offer too. To our untrained eyes, most of these excavators looked to be in relatively good condition, and judging by the Japanese writing, as well as the rendition of a bird of paradise on one of them, they originally hailed from the far east.

Larger excavators were also in evidence. No less than five Cat 375L hydraulic quarry exca-vators were entered in to the sale, while two PC1100-6 were offered, bringing the total of larger excavators to 81.

There was far more in the yard, including haul trucks, graders and those fascinating guess-what’s-in-the-crate con-signments of parts.

So, if you need some more machinery on your site, why not get along to it?

AUCTION YARD022

Keith Lupton, general manager of WWA said: “Check the condition of items like the idlers and the final drive sprocket. If you can shave with the teeth, it won’t have been doing the tracks any good and a rebuild can be very expensive.He added that large Cat ‘dozers such as the D10 and D11 are rare, though they have been used on a few large infrastructure jobs, so they do come up from time to time.Far more common at auction is the D9L. These machines are popular in quarries, though as Lupton pointed out, this can be a problem. “These machines work hard and though the sand can make the blade look shiny, very often the blade is bent and torn.”

The time is on us for our most significant event of the year – and one in which all the world will have its eyes on. As construction sites grind to a halt all around the world, Saudi Arabia remains reasonably strong – but it’s ups and downs can be seen as a barometer for the rest of the GCC states, as its fortunes are closely mirrored by the rest of the Gulf.

Apart from this, a huge number of commercial and infrastructure projects in the region mean that even in these tough times there is still a demand for machines, and a thirst to know how to operate them safely. Here follows a bit about out host, and a few of the companies that are supporting the event.

It is the biggest show in our calendar, and it

will act as a barometer for the industry. Here

is a little about just some of the firms at

the Saudi PMV Show.

PREVIEW033


Saudi Aramco is the state-owned national oil company of Saudi Arabia. It is the largest oil corporation in the world with the largest proven crude oil reserves and production. Headquartered in Dhahran, Saudi Arabia, Saudi Aramco also operates the world’s largest single hydrocarbon network, the Master Gas System. It was known as just Aramco between the years of 1933-1988, an acronym for Arabian American Oil Company.

As of the end of 2006, its yearly production of only crude oil neared 3.4 billion barrels (540,000,000 m3) and it managed over 100 oil and gas fields in Saudi Arabia totaling at least 264 billion barrels of oil reserves and massive gas reserves.

Among those fields fully owned by the company is the Ghawar field, the world’s largest oil field; the Safaniya Field, the world’s largest offshore field. Despite the recent slump in crude prices, Saudi Aramco is still thought to be the world’s most profitable company.

Saudi Aramco dates back to 1933 when the Government of Saudi Arabia signed a concessionary agreement with Standard Oil, California (Socal) allowing them to explore Saudi Arabia for oil. Socal passed this concession

to a subsidiary called California-Arabian Standard Oil (Casoc). In 1936 with the company having no success at locating oil, the firm that became Texaco purchased a 50% stake of the concession..

After a long search for oil that lasted around four years without success, the first success came with the seventh drill site in Dammam, in a well referred to as Dammam number 7. The discovery of this well, which immediately produced over 1,500 barrels per day (240 m³/d), gave the company the confidence to continue and flourish. The company name was changed in 1944 from California-Arabian Standard Oil Company to Arabian American Oil Company (or Aramco).

In 1950, Aramco agreed to share its profits on oil sales 50/50 with Saudi Arabia’s government. In 1973 the Saudi Arabian government acquired a 25% share of Aramco, increased this to 60% by 1974 and finally acquired full control of Aramco by 1980. In November 1988 the company changed its name from Arabian American Oil Company to Saudi Arabian Oil Company (or Saudi Aramco).

From its headquarters in Dharan, on the eastern shores of the Arabian Peninsula, Saudi Aramco manages

virtually all of the kingdom’s enormous hydrocarbon enterprise. Saudi Aramco is engaged in the management of onshore and offshore oil fields, petrochemical research and development and operates its own fleet of oil tankers. The firm is responsible for 99 percent of the Kingdom’s proven crude oil reserves of 259 billion barrels (41.2 1010m³) -- about a quarter of the world’s total conventional oil reserves. That is more than double the total of Iraq, the country with the world’s second largest conventional oil reserves, and nearly 12 times the reserves of the United States. Recent output is more than twice the output of the next highest producer and nearly five times greater than the largest U.S. oil company. Russia as a whole produces almost 9 million barrels (1,400,000 m3) of oil per day, however, several different companies pump oil there, while Saudi Aramco is responsible for 99% of Saudi Arabia’s oil.

The company is also a leader in both the production and export of natural gas liquids (NGL), and a major producer of refined products. A programme is currently under way to expand gas production to meet demand for gas at home to power the Kingdom’s domestic economic growth. (Photo: BARCO)

Any machine that uses oil is going to need to filter it. This is good business for one company, who since the 1940s have developed and manufactured a wide range of filters, air intakes and other components. The MANN+HUMMEL Group was established in Ludwigsburg, in southwest Germany in 1941. The motor spares trade is supplied with filter elements under the MANN-FILTER brand name in the same quality as that supplied to OEMs. For the general industry MANN+HUMMEL develops and produces industrial filters and filtration systems for the engineering industry and units and systems for materials handling in the plastics processing industry.

According to the company, the most important product in the MANN+HUMMEL product range for the reduction of emissions is the SMF-AR diesel particulate filter. It is

designed for use in applications with low exhaust temperatures as is usual with mobile machines. In comparison to other solutions on the market the SMF -AR offers the advantages of active regeneration without any machine downtime, low maintenance and operating costs, and a wide range of use for many applications.

The SMF-AR is equipped with a high performance filter element. In contrast to conventional ceramic elements, this enables a higher ash holding capacity and therefore longer service intervals. In addition, the MANN+HUMMEL filter element is durable for the life of the product and is easy to clean. Conventional ceramic elements on the other hand have to be replaced after a number of cleaning intervals.

A further advantage of the diesel particulate filter SMF-AR from MANN+HUMMEL is that the

regeneration process takes place without any machine downtime. The regeneration also requires no external energy. The soot burn-off is introduced automatically when the ideal amount of soot for electrical regeneration has collected in the filter element. Ignition of the soot is made through radiant heat from heating elements. The heating elements ensure consistent heating of the radiated soot area. An additive is automatically dosed which reduces the ignition temperature of the soot particles and enables a quick and consistent soot burn-off. The heating elements are designed to ensure that a fully automatic ignition of the soot layer is made in the shortest time possible. Regeneration is made without any additional increase of emissions. A costly fine-tuning of the engine is not required. The SMF -AR can be fitted to a wide range of applications.

Think of new housing in the UAE and what are your first thoughts? Chances are you are thinking of giant tower

blocks, thirty-stories plus. However, not everybody

wants to live in a high rise. There is still a demand for more tra-ditional style villas, with walk-able streets and shady willow trees overhanging. There is also the important point that in such communities, independent trad-ers can be allowed to thrive, chil-dren can walk to school and life is generally comfortable and settled – a community in other words.

The downside of such living

is that many old-style villas are wearing out, and have few of the efficiencies and conveniences expected for today’s lifestyles. Happily, several developers have cottoned on to this and are build-ing traditional villas, with a mod-ern twist.

One such project is the Al Reef development, near to the Al Raha beach in Abu Dhabi. When complete, the complex will comprise of a couple of thou-sand villas, some medium-rise apartment blocks and a panoply of schools and shops, each built in the style of a different archi-tectural style or ‘theme’, be it traditional Arabic, desert or con-temporary for example. Each

has modern cooling, an abun-dance of plumbing and some will have a pool.

Building one or two low rise villas presents few problems for any contractor. However, when they number in the thousands, becoming effectively a small town any efficiency gained in construction can be extreme-ly valuable in terms of time and money.

PRECASTAs all the villas are made of pre-cast concrete, effectively a kit of parts, it makes sense to batch concrete onsite. The lead con-tractor Fibrex does just this, with a pair of batching plant onsite.

We didn’t get a chance to inspect this installation during our vis-it, but it appears to have two medium to high capacity plants. What sets this development apart, though is a precast facto-ry owned and operated by the contractor adjacent to the con-crete plant.

STEELEfficiency is further increased by the foundation of a small steelworks onsite. This will be used for rolling and form-ing joists and so on for use in the project. Using this will help avoid the various peaks and troughs in demand and sup-ply that were seen last sum-mer, meaning the budget for the project will be easier to keep to schedule.

SURVEYINGThe most clever part of this project, though is the way the surveying equipment works. Regular villa construction is most closely associated with the traditional method of the survey-or using a theodolite to meas-ure distance and angles. This took time, and the data needed to be recorded manually. The last few years, particularly as projects have got bigger, have seen a shift away from this type

of technology and on to what are known as ‘total stations’. These devices can read the horizon-tal and vertical circles electroni-cally. Understanding how these new machines work exactly is something only an engineer would be able to explain, but suffice it to say they don’t rely on bands of light seen through prisms, rather digital imaging technology takes over.

The newest technology to be embraced by the region is sat-ellite positioning. This technol-ogy can incorporate distance, direction and difference in height between survey points. A satellite-based surveying sys-tem is simply using an elec-tronic distance measurer that does not need direct line of sight between survey points. Instead, a GPS receiver needs to have a direct line of sight to a sufficient number of satellites. Although the term ‘GPS’ is used as a sort of generic trademark to describe satellites in orbit, it actually refers to a ring of devic-es put in space by the Ameri-cans, and allowed to be free for civilian use. In fact, any brand of surveying equipment could equally be using the Russian GLONASS system, or the soon to be launched European Gali-leo network, which counts Saudi

Arabia among its backers. Fibrex have chosen to buy its

surveying equipment from Jap-anese company Topcon. Eng. Ibrahim pointed out that the company had been impressed with the technology after a dem-onstration. “About two and a half years ago, Topcon showed us a machine – a 752 – and we thought it had very good speed and efficiency” he explained. Since then, the firm have invest-ed heavily in the equipment, having bought a hyper GA base station, two rovers and eight 760-series total stations along with five laser levels.

As the site is in Abu Dhabi, Fibrex opted to have its own base station. Other sites in Dubai though can take advan-tage of centrally located base stations. Topcon’s Talal Han-na explained; ‘In Dubai we have what we call reference stations, which means that the munici-pality is handling these ones. What you have to do is to sub-scribe and you get the correc-tion through your phone card.’ He explained that depending on location and what the custom-er has ordered, there were a number of ways of linking to the base and obtaining corrections automatically, with Bluetooth and GRPS links as possibilities.

GPS Eng. Ibrahim says switching

to e-surveying was a wise move.

Electronic Distance Measurers (EDMs) accurately measure distance by measuring the time it takes a laser to travel from the EDM to a prism and back. Before the introductionof EDMs, taping or chaining was used to make accurate distance measurements.

A Total Station is the most accurate surveying device because it incorporates an electronic or digital theodolite, an electronic distance measuring (EDM) device and a microprocessor in the same unit. Total stations can automatically measure horizontal and vertical angles as well as slope distances from a single setup. From this data they can instantaneously compute horizontal and vertical distance components, elevations and coordinates, and display the results on an LCD. They can also store the data either on board or in external date collectors. From the total station, data can be downloaded easily to a personal computer.

The readout is done by a rota-ry encoder which can be abso-lute or incremental using light and dark radial bands In the lat-ter case the circles spin rapid-ly, reducing angle measurement to electronic measurement of time differences. Additionally, lately CCD sensors have been added to the focal plane of the telescope, allowing both auto-targeting and the automated measurement of residual target offset. All this is implemented in embedded software.

The base station is always in the same place, so you, as an ngi-neer can send corrections when-ever you go to the site so you don’t have to take the base. All you have to do is carry the Rover and then you will get corrections all over the site.

The base station can run on large (car type) batteries so it can send all of the corrections continuously.

In fact the surveyor normal-ly would go and put the base on a known point and wait until it sends the signals for the correc-tions, so he can go on his site at any time and find the corrections have already been done. So he’ll

find the corrections every time he works.

Not every site has its own base station, though. Fibrex fde-cided to have its own base sta-tion, so they don’t have to do the work twice so every surveyor can come and hook up his base and then go onto site with his portable rover.

Total Stations are improving all the time as well - the recently launched Topcon It offers 2000 meters Non Prism Long mode measurement, whilst being almost 10 percent smaller in size.

So poles, or almost any sur-face can be measured at prac-tical distances up to 350 to 400 meters.

FUTUREThe satellite technology that drives the surveying equipment is finding its way into yellow iron as firms modernise their fleets. Construction machines such as graders, excavators or bulldoz-ers can be navigated directly via satellite with the highest pre-cision, and one such system is offered by Topcon.

Making an own reference station obsolete. Topcon and

service provider Ascos from Germany together developed a new modem-based solution

for 3D-Machine Control on the building site. An integrated solution illustrates all processes from start to finish. Basis of this complete solution is an indus-try-specific mix of the success-ful correction data and services, which ascos offers for satellite-based processes. With the pre-cise real-time service (Ascos PED) for example the machine can be steered with a deviation of maximum 2 cm (position) and/or 3 cm (height). Measur-ing or documentation however requires a higher accuracy with-in the millimeter range, which can be obtained by recalcula-tion through the virtual post-processing procedure.

Measurements using satellite positioning is fast and precise with a minimum of personnel. Thus preparation and shifting times are reduced substantially.

We hope to visit a jobsite where machine automation is working very soon.

Meanwhile, when it comes to GPS surveying, as Fibrex have found out - the sky is the limit.

can be used up to 2km away.

During the last decades, Top-con has brought many innova-tive solutions to the industry that offers the contractor significant productivity increase and great-er ease of use. That’s the key to leadership, and the reason Top-con is a world leading supplier of positioning instruments.

Philippe Akl, GM of equipment maker Topcon speaks about his firm’s role in the region.

SURVEYING’SFUTURE IS THREE-DIMENSIONAL

Q & A046


Go anywhere in the world and you’ll find surveyors, engineers, contractors, geodesists, govern-ments relying on Topcon instru-ments and systems to make sure the work they do is precise and under their control.

WHAT IS THE IMPORTANCE OF SURVEYING EQUIPMENT ON A CONSTRUCTION SITE?Surveying continues to play an extremely important role in con-struction. It is required to plan, construct, and maintain almost any construction project whether it is a highway, railroad, building, bridge, tunnel, canal, sewerage system, pipeline, oil platform or others. The positioning equip-ments are the first to arrive to a construction site and the last to leave. The engineering sur-veying can affect seriously the overall project workflow, speed, efficiency and profitability.

I am happy to see that local construction companies, in par-ticular in the GCC, started to rec-ognize this reality. As a result, they are ready to pay a premi-um for seamless solutions that guarantee a genuine produc-tivity boost. This market matu-rity encouraged us to extend our activities and offer, for the first time in the Middle East, advanced solutions like Machine Automation and 3D imaging and scanning systems.

WHAT SETS YOUR SURVEYING EQUIPMENT APART FROM THE REST?What sets Topcon equipment apart from the rest will always be Topcon TM-1 policy. TM-1 means ‘Time to Market Number One’ which drives the compa-ny to continually bring needed, world-leading products to mar-ket first.

Topcon is different because of its high focus on technology and true innovations. As mentioned earlier, during the few past years

Topcon introduced “World’s first” to the market more than anyone else. We saw recently GPT-7000i, mmGPS, and GR-3 as good examples of Topcon unique solutions.

WHAT ARE THE ADVANCES IN TECHNOLOGY IN TERMS OF SURVEYING EQUIPMENT CAN WE LOOK FORWARD TO IN THE FUTURE?Mixing and matching different kinds of technologies to create new solutions will be the main criterion that will drive the future advances of our industry. Good examples on this blending of technologies that we saw recent-ly from Topcon are GPT-7000i, Imaging Station IS and mmGPS.

Topcon Imaging Station is a robotic total station that offers the added productivity and ver-satility of integrated digital imag-ing, a world’s first technology Topcon introduced in 2005 with its GPT-7000i total station.

The IS advanced 3D modeling capabilities allow for 3D model creations with image integration.

We started seeing compa-nies in UAE using it for volume measurements and the feedback so far is very positive.

Another example of technolo-gy mix is our mmGPS that com-bine Topcon’s existing GPS Plus system with Laser. Topcon’s mmGPS delivers level accuracies to within a few millimeters.

I believe this trend will contin-ue in the future and we will see more solutions emerging from such smart blending of technol-ogies.

WHAT ARE THE ISSUES AF-FECTING YOUR INDUSTRY? WHAT ARE THE CHALLENGES THAT YOU FACE?Over the past several years, acquisitions have played a fun-damental role in the strategy of major suppliers of positioning equipment, aiming to penetrate

still strong for GPS systems. new market places, expend their product lines, benefit from econ-omy of scope and scale or assure a stronger presence in the mar-ket. In Topcon’s case, this has led to partnering with or acquiring many companies recently. This joining of companies will definitely give us, particularly in the Middle East, excellent dis-tribution networks and will pro-vide our dealers with additional opportunities for growth.How to create the synergy aris-ing from this integration will be our challenge to truly material-ize the huge benefits that it will proffer for us in the Middle East market.

WHAT IS THE FUTURE OF THE SURVEYING EQUIPMENT INDUSTRY? Our industry is constantly changing. It is being transformed

and developed by new technol-ogies and a strong desire from the market for more computeri-zation. This emphasis on the efficien-cy is driving a profound change in the nature of surveying where the surveyor is becoming more a data manager.

I foresee an escalating trend of 3D scanning and imaging solu-tions to become a standard for data capturing.

It may seem strange to say “the standard” today but the future is something else.

We are at the dome of a new era, a future that really absolute-lyis truly 3-dimensional and this will change the positioning indus-try and the way surveyors work forever.

Over the past few dec-ades, concrete has played an important part in shaping build-ings all over the world

– and in turn so has formwork, as it acts as the mould which casts and shapes concrete.In reinforced concrete construc-tion, up to 70% of the cost and a bulk of labour time is associated with formwork.

Every construction site has individual requirements and the type of formwork chosen.

“It depends on the structure, the quantity and educational level of available labourers, the budget, the aimed floor cycle period, the thickness of the wall, slab, column or whatever is going to be concreted. Therefore the contractor and the formwork supplier should work together as a team to help the contrac-tor achieve his expectations by using the most cost effective formwork solution,” says Hans Joachim Rau, managing direc-tor, Peri.

Peri introduced the Skydeck, a panelised slab formwork, to the UAE market during the Big 5 in 2008.

Skydeck is a lightweight alu-minium slab formwork sys-tem for slab thicknesses up to 950 mm.

“No individual component exceeds 15 kgs. The system is easy to clean and needs fewer props: for a 3.45 m² field, only one prop is used with a 400 mm slab thickness. Through the use of the drop head, removal

of formwork can take place the following day which frees up material for the next concreting cycle,” says Rau.

The company also introduced the LICO lightweight column formwork which allows the form-ing of columns without a crane. LICO can be used for square and rectangular cross-sections with widths ranging from 20 cms to 60 cms. With additional ties, shear wall sections up to 1.30 m long are possible. LICO column ele-ments are available in heights of 0.50 m, 1 m and 3 m. All elements can be moved by hand and the connecting parts are permanent-ly attached to the panels, which mean they cannot be lost.

“This has a special advantage on the local market as the con-struction sites are very big and material (especially if it is small) can get lost easily,” says Rau.

Falls from elevated locations are among the most common

types of accident in the con-struction industry. These acci-dents are mainly caused by insufficient safety measures at the working platforms and verti-cal access facilities, and also due to the constantly changing work-ing conditions. With health and safety issues becoming vitally important on construction sites, the contractors in the UAE have begun relying on formwork sys-tems that deliver both quality and safety.

“Doka manufactures its prod-ucts in Europe, where safety requirements are very high. We also offer a wide array of safe-ty solutions that minimise acci-dent risk and make for a fast and cost-efficient workflow,” says Peter Vogel, general man-ager, Doka Gulf

Doka working platforms with comprehensive safety features, and permanently mounted ver-tical access facilities contribute

towards enhancing workplace safety during forming opera-tions. The pre-assembled work-ing platforms are ready for immediate use on the site, and ensure a maximum of safety from the first moment the crew step onto them.

The platforms, with their hot-dip galvanised components and compatibility with the framed formwork Framax Xlife and large-area formwork Top 50 sys-tems, ensure high cost-efficien-cy and the great flexibility in the forming operations.

Doka beam H20 top, is a form-work beam with a built-in shock absorber, which prevents the timber beam from cracking or splitting when it falls down from a height, which results in an exceptionally extended life span. The framed formwork Framax Xlife, with its plastic-coated panel has been developed for extreme-ly long life. In this system there is long lasting plywood embed-ded in a very strong frame.

“The main advantage of this formwork on the jobsite is that it can be used from the ground floor till the completion of the project especially for high-rises as it has a long life span,” says Christian Pongratz, regional product manager, Doka.

Doka Gulf is currently in the process of constructing of a new warehouse and office building in Jebel Ali Free Zone. “Apart from the new facility of 50,000 m², we permanently invest in materi-al stock between US $54.4-64.4 million (AED 200-300 million) in order to match requirements of our clients. Some major projects we are involved in have been delayed, but we believe that the market will not deteriorate fur-ther,” says Vogel.

Ulma was founded in 1961, entered the UAE market four years ago and is currently based out of a 13,000 m² office and stockyard in Dubai Investment Park. “We are opening a smaller

stockyard in Abu Dhabi because of the shift in the project base with the cancellation of many projects in Dubai,“ says Andreas Gathmann, general manager, Ulma.

But Gathmann remains opti-mistic about the UAE market.

“Construction has not stopped completly, it will just become more realistic and feasible projects will go ahead at a nor-mal pace. We will see less of the futuristic or outlandish devel-opments which were being announced earlier,“ he says.

Ulma has introduced a versa-tile lightweight climbing system that can be modified – accord-ing to the customer’s wishes – to a rail guided or self climbing sys-tem. Both options offer standard perimetral protection. This climb-ing system has a mobile hydrau-lic unit (if the self climbing option is selected) with a capacity of up to 50 kN (kilonewton) and can also be used to provide lifting for

materials. The system also incor-porates access scaffolding option between levels.

The company has also devel-oped and introduced its slab alu-minium drop head panel system. It is easy to assemble since one team erects the supporting grid and at the same time another team or person can start putting the lightweight aluminium pan-els in place. The heaviest piece of the system weighs 16 kgs. For the shuttering surface there are 2 options: a high grade Finn-ish plywood with phenolic cov-er or plastic sheet cover. Both are embedded in each panel and ensure that more than 100 uses can be achieved, if they are cared for properly. On striking, all material can be easily trans-ported by hand to the next lev-el and the only parts remaining in contact with the slab are the unique dropheads. This system can be used to accommodate Ulma’s galvanised steel props

“The advantages of this sys-tem are: it does not require a crane, saves manpower, clients can deshutter very early (within 36 hours) and the resulting sur-face is impeccable,“ says Gath-mann.

According to the contractor, even a typical cycle of 4 days per floor could be achieved, but due to the site’s location adjacent to residential buildings, night shift work is restricted to activities such as pouring of concrete.As the building rises, the size of the columns reduces by 100 mm every 15 floors.

The beginning of the original rock-body dump trucks


JUMBO There’s a Mack AP some-

where behind that jumbo, used on

the Hoover Dam.

HAUL TRUCKSLOOKING HANDY


Moving rocks between the quar-ry face and the crusher has always been an arduous

job, with enormous trucks haul-ing the rocks about the place. However, it was all too common for rocks to be moved in small pick-up trucks, or by cart which was obviously a very low-produc-tion way of doing things. Early in the history of moving rocks, the market was cornered by US-based firm Mack. The company developed a new mod-el – the AC - back in 1915, which could carry a payload of up to ten tonnes. While this sort of pay-load is far removed from the 300 tonnes and more seen today, it was a vast improvement on the few hundredweight that other

early trucks could manage. As the First World War was raging, Mack secured a large order from the British army, where the coals-cuttle-shaped bonnet prompt-ed the nickname ‘bulldog’ as it gave the truck a sort of droopy-mouthed appearance. The name stuck and later the firm adopt-ed the tough canine as its hoodmascot ornament. Of course, construction projects got ever bigger, and while most companies were trying to sur-vive the great depression, Mack tasked itself with building a truck suitable for the most enormous project in America at the time – the Hoover dam. Known as the model AP, the new-comer retained the chain drive and rather vintage appearance of the original, the engine, chassis

and rockbody had been enlarged and extended to give the truck a 25 tonne payload – more than two and a half times more than the original. As the truck was giv-en solid wheels and special sus-pension for the loads, it became unsuitable for highway use, and so creating the first true off-high-way truck.Many people outside the PMV fraternity think that ‘off-high-way’ means that these trucks have superior off-road capabili-ties. Of course, the opposite is true. Quarry roads should be smoothly graded so as to keep the truck chassis from twist-ing when the truck is carrying a load. Also, tyres for these things are mind-bogglingly expensive, and anything to prevent excess wear should be considered. The

current largest off road haul trucks are the Liebherr T282B and the Caterpillar 797B which both have payloads of 400 short tons. Even though these trucks are similar in capacity the Cater-pillar is referred to as a mechani-cal truck since it uses a big diesel engine(or sometimes two) and big transmissions to power the rear wheels. The Liebherr is referred to as a diesel electric truck since it uses a diesel engine linked to an alternator that gener-ates electricity which is convert-ed to AC used to power two giant electric motors found on the rear wheel assemblies, similar to a locomotive. Besides Liebherr and Caterpillar, Hitachi, Terex, Komatsu and others also fabri-cate such off road haul trucks in different capacities. Rock on.
