3. CONSIDERING THE TECHNOLOGY ELEMENTS

The construction of bridges and dams is a highly skilled process.

In order for the design of a bridge and dams to be carried out,

special equipment must be used to complete the project due to the


size and weight of the materials. According to the Transportation

Research Board website, international construction companies work

together to design, build, and supply the correct and most recent

equipment for bridge construction.

3.2 BUILDER

o According to the Norwegian-based international construction

company has worked with other construction engineers worldwide to

develop the Dams builder machine. The machine is lightweight, easy

to assemble, and moves on fixed rails. The Dams builder is used to

move materials and construct the frames of concrete bridges. The

machine is designed to be able to move and support anywhere from

100 to 400 tons of bridge building materials.

3.2 GANTRY CRANE

o Gantry cranes are used to cost-effectively erect and build

segmented bridges. The NRS website explains that gantries are

built either as overhead or under-slung machines in order to meet

specific bridge construction needs. Gantry cranes are simply very

large cranes that are used to maneuver and quickly build a bridge

one beam at a time. The under-slung gantries operate by using

hydraulic cylinders to support the various bridge segments. The

overhead gantries suspend and move segments through the use of

specifically-designed tension bars.

3.3 BEAM LAUNCHER


o A beam launcher is used to position and install pre-cast concrete

beams for bridges that are being built over a body of water or

viaducts. When building a bridge that is crossing unsteady ground

or has high piers, the beam launcher is used to position the beams

correctly and safely. The two kinds of beam launchers include

single box and twin-truss type. The single box beam launcher is

lightweight and used for erecting pre-cast beams on tight

horizontal alignments. The twin-truss beam launcher is used

worldwide for constructing large scale bridges.

3.4 STRADDLE CARRIER

o A straddle carrier is used in place of a gantry crane when heavy

materials must be lifted at casting yards, factories, storage

areas, ports and marinas. The NRS website explains that gantry

cranes are attached to fixed rails, while straddle carriers are

built on tires with motorized wheels to make construction and

material mobilization possible. A straddle carrier operates by

using hydraulic systems, winches, ropes, and electric and

hydraulic motors.

Lime solutions machines

Mobile crusher machines

Crushing equipments

Tractors and trolleys etc.

5. BENEFITS OF DIRYAR E DORR

Utilization of the irrigation and hydropower potentials of river

(Diyar-E-Dorr) represents the least cost option available to

Pakistan to sustain as well as expand its irrigation and power

generation capacity. Whereas the Rojoya dam Project in the late

2000’s provided basic infra-structure for integration of our

largest irrigation system. Rojoya Dam could assume similar role

for making an earnest start towards further unified national water

resources development-cum-management.

5.2 ROJOYA DAM PROJECT WOULD PLAY VERY IMPORTANT ROLE

a. Replacing storage lost by sedimentation in existing

reservoirs at TARBALA (estimated about 3 MAF by the year 2000).

b. Providing additional storage to meet existing water

shortages during early crops sowing period of April-June.

c. Reducing dependence on imported fuels.

d. Creating employment for 30,000 persons during construction.

7. FUNDING RESOURCES

Funds are the basics needs for execution of any project. Funds

also play the back bone role in the project planning. For this

tremendous construction funds are collected from to resources.

Private sectors such as those people who are willing to invest


their share in dam’s constructions for their social services like

Era, UN (Government of America), china and Turkish government etc.

On the other hand project is governed by government of Pakistan

for the sack of eliminating short fall in HAZARA DIVISION. As this

dam is the need of government to facilitate the people in HAZARA

DIVISION to overcome the short fall as well as agricultural problem

(irrigation). Due these major reasons government of Pakistan is

interested in this project to solve this major problem. This dam

is also helpful in development of POF (Pakistan ordinance factory)

which suffered with short fall of electricity and water facilities

provided by government.

9. RISKS

The project and construction of a dam present special problems

demanding high knowledge of several sciences and techniques: Geology,

foundations, Hydraulics, properties and treatment of materials, etc.

Perhaps, that is the reason why it requires, more than any other

construction project, the collaboration of several specialists and team

work. As a conclusion, the plan and the project have special importance

in dam construction, for the corresponding works and for the river

diversion system.


9.1 CONSTRUCTION RISKS, DAMAGE TO THE WORKS AND

ADVANCED LOSS.

RIVER DIVERSION.

The maximum flood to be diverted is the major problem in designing and

determining the dimensions of the diversion elements. It must be

determined based on the following dilemma:

If we fall short, floods higher than the diversion capacity will be

spilt over the diversion works and will flow through old natural

course, flooding the works that are being built.

If, in order to avoid this, a very wide diversion is done, it may be

excessively costly. The drainage capacity of diversion tunnels is

generally designed to have a 30 to 50-year return period flood event,

in order to prevent flooding during the construction. Therefore, the

two major risks associated with dam construction during the

construction stage are:

The possible flooding of the works due to rain-induced floods

(they are very sensitive to natural hazards), as such flows are

not contained by the diversion elements.

The risks derived from the necessary explosions to demolish the

temporary cofferdams.

Auxiliary works. Due to the fact that access roads are

provisional, no coating layer is applied on them, meaning that

they are exposed to rain and possible floods. In general,

temporary works (roads, bridges, fillings, etc.) are very affected

by landslides induced, for example, by hard rainfall; as well as

natural hazards (earthquakes, etc.).


Materials storage warehouses and construction machinery are highly

exposed to landslides, if they are located in the proximities of slopes

susceptible to land sliding.

9.2. EMBANKMENT DAM (RISK)

These dams do not withstand being overtaken by floods, both during

construction and once under operation, as the little cohesion of the

materials they are composed of could be reduced, which might cause the

collapse of part of the wall, as well as filtration areas. That is why

it is important to carry out a good study on historical rainfall on the

river during the project stage.

The dam toe is one of the most important elements in the construction of

concrete facing dams. Its correct formation is essential to assure the

water tightness of the dam. Internal erosion may develop in the joint

zones between the impervious material of the dam core and the integrated

concrete structures (bottom drain, etc.). In order to prevent this

phenomenon, they must be planned and constructed with special care.

9.3. DOUBLE CURVATURE DAMS (RISK OF STRUCTURE)

They are very slender and may adopt very daring and complex shapes,

which allows them to be very high and with small thickness. This

complexity requires great skillfulness and experience from the

constructors, who must resort to uncommon construction systems and the

use of expensive construction equipment as well. Due to this, any

mistake made either during the planning or the project stage may lead to

future accidents.

Generally, because of the large loads transmitted to the ground due to

the “arch” effect, it must be resorted to extensive foundation works.


Concrete may be altered by the presence of meteorological or

environmental agents, by increasing its resistance in direct proportion

to its thickness. Increase in thickness may lead to being less demanding

with the quality of the materials in order to save costs. A double

curvature dam must be monolithic, so that the dam site is required to be

resistant and little deformable, resorting if necessary to ground

improvement techniques.

9.4. LEGISLATION ISSUES IN DAM CONSTRUCTIONS

(RECOMMENDATION BY EIA)

Providing recommendations for the future:

Providing a brief assessment of the regulatory framework for the

management of environmental and social risks associated with hydro

projects, giving specific attention to the enforcement of control

measures.

Providing a brief assessment of the capacity development needs for

professionals and institutions involved in the management of

environmental and social risks.

Providing recommendations for further development of both the

regulatory framework and capacity.

The objective of developing EIA guidelines is to support the relevant

institutions especially Environmental Protection Agencies, Planning and

Development Departments, financial lending institutions, consultants and

civil society organizations in effectively undertaking and reviewing

EIAs of large hydro dams to ensure environmental and social safeguards

compliance as per the legal framework in the country.
