TYPE OF CLOSURE: SHOULDER

================================================================

THE PLAN SHALL CONTAIN THE FOLLOWING:

The Advance Warning Area

This area is used to advise motorists that there are temporary conditions ahead of them which require

particular care.

The Transition Area

This is the area in which drivers are required to take an action, such as:

shift position on the roadway without reduction in the number of lanes;

merge two lanes into one (lane drop);

cross the central median (crossover);

to enter a detour completely separate from the road under construction.



The Stabilising Area

The purpose of this area is to allow traffic flow to stabilise after negotiating a transition area before

reaching another change of condition.

The Buffer Zone

This is the limiting form of stabilising area. It is normally used between a transition area and the work

area.

The Work Area

This area must be adequately defined by delineators in the less complex conditions. Where there is a

risk to traffic or workers of vehicles entering the work area, temporary barriers of a standard sufficient

to prevent vehicle penetration are recommended.

The Termination Area

This area involves the return of traffic to normal flow conditions. In simple cases, this can be achieved

by a relatively rapid taper of delineator signs.

THE SIGNAGE:

- The signs will be the right size (1.2m for rural, and 0.9m for urban, as per SARTSM chapter 13), with the

correct colours and have a retro- reflective background. All signs will be placed just off of the road

surfacing (tar), and are not to be obstructed by any netting, etc.

- The signs sequence for CONSTRUCTION will be as follows: the men at work 800m with a flag man/women

from the work area then the 100km board at 600m, the 80km at 500m, the advance warning at 400m, the 60

km at 200m before the work area, at the work area a flagman/women per machine and the delineators will

be spaced at 50m intervals and placed on the outside edge of the surfacing. The 120km and end thank you

board will be at the end of the termination area to speed up the traffic again. This sequence will not

exceed 5 km’s. An open area of minimum 5.0 km’s must be allowed between sign sequences.

- The sign sequence for STOP/GO will be as follows: the men at work 800m with a flagman/women from the

stop/go, then the 100km board at 600m, the 80km at 500m, advance warning at 400m, the stop/go ahead at

200m, the 60 km at 100m before the stop/go with a flagman/women, the work area will be covered with

delineators spaced at 50m intervals. The 120km and end thank you board will be across the 200m mark of

the opposite set of signs. The signs and flag men/women will be on both sites of the highway. The stop/go

sequence will not exceed 3km, with an open area of 4km before the next one commence. There will not be

more than three (3) stop/go at any time in one section.

- The sign sequence for SHOULDER DROP (Offloading import soil, offload of equipment or stationary

equipment such as compressors parked on the shoulder) will be as follows: the men at work 800m with a

flagman/women from the drop site, the 100km at 600m, the shoulder blocked sign (TGS133) at 600m, the

80 km at 400m, this will be applicable on the other side of the highway also. The 120km and end thank you

board will be across the 500m mark of the opposite set of signs. The signs and flagmen/women will be on

both sites of the highway.



At all shoulder drop closures, the start and end of the area will be tapered by means of

delineators at intervals of 10m, with a flagman/women at the start of the taper.

- The numbers of all signage will be on the drawing next to the sign and the different areas indicated.

- Delineators will be next to the road every 50m where the closure is in operation, and will have sand bags

on them.

- The speed of the traffic will be reduced to 80km or 60km per hour, as appropriate, in the working area and

after the work area the speed will return to 120km per hour, all boards will be in place as seen on the

drawing.

- Where only REINSTATEMENTS or PRE-CLEARING are done, the signs will be moved along as the

reinstatement team is moving. A rotary flag man will be moving with the team and a stationary flag man

will be at the men at work sign. The sign sequence will be as follows: the men at work 600m, the advance

warning (TW339) at 400m and the 80 km at 200m

- The sign boards to be used is Warning signs (men at work TW 336-WA, advance warning TW 339, stop/go

ahead TW 343-TIN11.2, end thank you TW 336-TIN11.4, road narrow to one side TW330), commonly used

Temporary Regulatory Signs (120 km/h - R 201-120), (100 km/h - R 201/100), (80 km/h - TR 201-80), (60

km/h - TR 201-60), (40 km/h - TR 201-40), control Regulatory Signs (stop/go – R1.5A R1.58) and delineators

of 0.8m high – TW401 & TW402 shoulder blocked sign - TGS133.

- The boards will be a minimum of 1.2m in size, and the sand bags that is going to be used is a minimum of

15kg there will be 4 or more on each signboard frame at the corners. The sand bags will be filled with sand

and not with stones.

FLAGMAN/WOMAN:

- In the work area there will be a flagman/women at every activity that will take place.

- Flags will be used that are at least 450mm x 450mm in size, that’s made of a red cloth with a fluorescent X

on it.

- Flagmen/women will be located far enough from the work area to ensure that drivers have sufficient

distance to slow down before entering the work area.

- Distinctive PPE clothing will be worn by the flagmen/women (reflective jacket or bright colour overall with

reflector strips on the jacket and trousers.

- Flagmen will be trained and inducted.

TYPES OF CLOSURE:

1. Pre clearing of work area.

2. Normal construction work.

3. Reinstatement & Testing.

4. Shoulder drop – Compressor.

5. Stop/Go – Blasting & Special circumstances.

Delivery’s to be incorporated with points 4 & 5, whichever is applicable.



THE FOLLOWING RECORDS WILL BE KEPT:

Road Traffic Signage control register

Road Traffic Control Training records

Daily Road traffic plan Inspection Records

RISK ASSESSMENT

1. The following risk should be considered when working on roads and freeways.

Danger to drivers, danger to workmen, danger of collisions caused by work

activity or confusion caused by incorrect signage, danger of blocking view

caused by bystanders, crime and theft on site. Remember you may lose signs

overnight so have spare ones on site.

2. Pre-Planning

Go to the site and look for dangers, a proper risk assessment is the key to

success. You need to look out for: blind rises, blind bends, pedestrian traffic,

even if not allowed on a freeway, weather conditions, rainy or tends to have

fog, cattle crossings, traffic density, and general traffic behaviour.

Place your signage with intervals of at least 50m separation between signage.

No painting of any road surfaces are allowed, it is an offense. Stopping on the

freeway is not allowed, so your vehicle needs to be clearly marked in visible

fashion. Your rotating light and hazards of the vehicle should remain on and

preferably 1m from the road surface. This means not in the emergency lane

but 1m from the end of the road surface on the grass. Wear a reflective

jacket at all times.



3. Requirements on Site

You need to have the following on site:

Generators and lights for night and or for poor visibility working

Spare torches with batteries

Road Signage.

Portable Toilets

Reflective jackets, full PPE for all staff members working in the road

or not

Risk Assessments

I.D document copies of all staff members , required when admitted to

Hospital

Roll calls and Attendance registers for staff and site vehicle details

Amber rotating /LED lights for the site vehicles.

Workman’s Compensation Number and relevant documents

Appointment letters as per OHS ACT

First Aiders documentation and equipment

Proper First Aid Kit as per OHS Requirements

Camera to record progress and also to record an incident that might

need to be documented.

Way leave and any documents required to work on the road and

metro areas.

Manhole barricades and trenching barricades

Measuring wheel

4. Danger to Drivers

Drivers are in control of the vehicle and the signage is there to tell him/her

what to expect on the road surface, therefore it is important to make sure all

signage is set up correctly before commencement of work.



The signage must regularly be inspected by the appointed Construction

Supervisor.

5. Planning

All planning should be done before hand. You need to know what you are going to

do work wise, how long it is going to take, where it is going to be.

You need to look at traffic specific problems and also a plan for an emergency

situation i.e. that your work is taking longer than expected or it starts to rain.

On a highway you need to put up signage on both sides of the road and in both

directions of the highway. Except for normal construction were signs on one side will

be sufficient.

6. Highways 0 -120km/h

If the maximum speed is high, more signage needs to be correctly laid out. Blind rises

and corners will require a longer period of warning to drivers.

Weather conditions should be considered when it becomes misty or the road

surfaces are prone to skidding.

If it rains no roadwork is allowed on any road surface because of the risk of skidding

and low visibility.

7. Signage

Signage should be deployed in the following fashion for a freeway and in

sequence below and in accordance with Chapter 13, Volume 2 of the South

African Road Traffic Signs Manual.

8. Securing Signage

All signage will be secure with sand bags filled with river sand, no rocks or

stones are allowed to be placed on the road surface at any time, even when

the signage has a supporting frame that will seem to collapse. By securing



them with sand bags they will remain upright and if a collision occurs the

damage will not be severe to the vehicle involved.

9. Placement of 100km/h speed restriction

100km/h boards to be placed first. This is to warn the driver and to increase

the distance to your site and that he has a longer period to slow down and to

react to the speed.

10. Placement of Men at Work Board

This warns you that your driver is to look out for pedestrians or pedestrians

that might cross the road. It also warns that construction is taking place.

11. Placement of No passing Signs

This warns the driver not to pass as there is a lane restriction.

12. Placement of Road Narrowing Signs

This is to warn that lane restrictions will be in effect shortly, and it will show if

it is on the left or on the right side of the road.

13. Placement of 80km/h speed restriction Signs

80km/h signs warn the driver to slow down.

14. Arrow Sign Boards

This is to show that the road is narrowing and that the traffic has to move to

the left or to the right in the direction of the arrow. Also make sure that if the

road is closed from both sides that it is indicated as such.

15. 60km/h Speed Restriction Sign Boards Placements

60km/h signs warn drivers to reduce speed and to slow done.



16. Placement of 40km/h Speed Restrictions (Only if applicable)

40km/h sign warns drivers to slow down and to reduce their speed. The

lowest speed on any Freeway is 60km/h and this will indicate the seriousness

of the operations.

Traffic Police Departments differ on this issue; however try to get the speed

low as possible for the areas where you work. This will reduce your liability if

someone gets injured in a crash as there were fair warning signs in place.

17. Placement of Cones and Delineators

All cones and or delineators are to be deployed 5m interval 100m from the site.

This is to warn that people are working next to the road.

The cones and or delineators should pass the site at least 50mts.

Cones and or Delineators are to be used to guide traffic and not for an informative

sign.

Note that a cone in the middle or shoulder of the road or freeway is a hazard and

could cause injuries or damage to vehicles.

18. Flagman/Women and their use

They need to know what signs are applicable to traffic and merely waving a flag

means and accomplishes nothing.

Flagmen/Women get tired, have a replacement available as it is hard work and a

very important function that or which often gets given to a less skilled employee.

Flagman/Women should be placed at the beginning of your Workman Board Signage

on both sides of the road and should be placed again 150m from your work area to

slow traffic down.

19. Lane Closure

You are not allowed to close any road if it is not written on your Way Leave, unless

you have applied for permission from SANRAL for such lane closure and written

approval thereof has been obtained.



20. Thank You Construction Work Ended Signage

This sign must be placed 100m away from the construction site. This will indicate to

the drivers that they may return to normal speed prior to the construction

operation.

21. Barricading

Barricading net to be used at all times. Barricading which has the support of two wire

strands spaced between anchor points and the barrier netting between the wires.

The first line wire must be 50 cm from the ground level and the second wire line a

meter from ground level.

Pegs must be used and placed at intervals of 5m and it should be 500mm below the

surface and 1m above the surface.

Barricading is not a substitute for signage.

22. Vehicle Markings

All vehicles to be marked with a construction vehicle sign and company logo.

Each vehicle must have a warning flashing approved high density amber/LED Light

(55W AE or similar) and must be visible in the day and when weather conditions are

not good (mist/fog).

23. Record Keeping

Maintain all documents as stipulated in the SHE Plan and NATIONAL LONG

DISTANCEROADTRAFFIC MANAGEMENT PLAN AND IMPLEMENTATION GUIDELINES

- How difficult is the task

- Complexity of task

- The chance that there will be a loss if task is performed improperly

- Any rating above 8 will require actions to address issues e.g. procedures, guarding, training etc.

PRIORITY GUIDE

Once a risk rating has been calculated, the following scheme should be used to assign priority of action. It should be

noted that if action is not taken within the time specified, then the continued toleration of the residual ‘downside’ risk

should be explicitly authorized. The suggested level of seniority for authorization is as shown below.
