5. CIDB Registration of 8CE

Mandatory CIDB registration of 8CE. Demonstrated relevant experience with a minimum of three verifiable reference projects completed in the last five years. Key personnel must have a minimum of five years of relevant experience. The contractor must have the financial and operational capacity to provide all necessary plant, equipment, and skilled labor (including eight oil skimmer operators) for a long-term, on-call contract.

Grootvlei Power Station is situated close to the town of Balfour in Mpumalanga province. The Power

Station consists of six units with a capacity of 200 MW each and the total installed capacity is 1200

MW. The first of six units was commissioned in 1969. Three of the units were mothballed in 1989

and the rest in 1990. Grootvlei was one of the power stations being recommissioned. The return to

service of the first unit occurred during 2007 and all six units were recommissioned during 2010. The

power station is currently 51 years old.

The Power Station is provided with pollution control dams, drains, and channels which are critical for

water conveyance and management during the operating life cycle of the power plant. It is critical

that through the operating life cycle, the above-mentioned infrastructure remains serviceable and

performs according to the stipulated design requirements.

Due to the nature of operations and the medium conveyed, silting and scaling up occurs which

compromises the design baseline. For this reason, it is required that the infrastructure be cleaned to

remove the silt accumulation on an as and when required basis.

• To ensure that existing structures, pipework, lighting, and all other components are not

damaged during the cleaning.

• To ensure that the original capacity of the dams is not increased during the cleaning (No

narrowing of the existing walls during cleaning to ensure stability is maintained).

• To remove sludge or sediment from the dam by agitating and pumping the slurry to the ash

dam from both the AWR dam (Method statement of the Contractor will be accepted).

• To remove the shreds and weeds or reeds on the skirt of the dam.

4.6 Cleaning of AWR (6 Million East and West) Dams

Inspections shall be carried out by the Employer to determine the extent of sludge accumulation in

the AWR dams. Should the dam capacity be highly compromised, then a decision shall be made to

clean the AWR dams by removing the solid material to a designated site for dumping indicated by

Employer

The following work shall be carried out:

• To determine the acceptable water depth.
• To determine sludge/sediment depth /volume.
• To determine the dam/pond depth.
• To determine the distance between dam/pond and the ash dam site.
• To determine the head pressure to be required by booster pump.

4.7 Cleaning of Ash Dam Filter Drains

Due to the water carrying silt particles during the draining process, scale forms in the drainage pipes

and this reduces the flow through the pipes. If not cleaned the scale increases so much such that

the drainage pipes block thus rendering the drainage pipe useless. It is therefore necessary to

periodically clean the drainage pipes to ensure that the flow through the pipes is as per design

(diameter of pipe not reduced by scale).

The following work shall be carried out:

• To assess the drain flows with the employer prior to conducting the works.
• To provide high pressure machine with pipework that can extend up to 150m.
• To provide water tankers for the supply of water during the high-pressure cleaning ‘as and

when required’.

• To conduct high pressure rodding of all the filter drains ensuring the scale is removed and

that all blocked drains are unblocked.

Inspect the filter drains outlets after the cleaning to verify that the outlet flow has improved.

4.8 Cleaning of Ash Dam Penstock

Due to the water carrying silt particles during the draining process, scale forms in the drainage pipes

and this reduces the flow through the pipes. If not cleaned the scale increases so much such that

the drainage pipes block thus render the drainage pipe useless. It is therefore necessary to

periodically clean the drainage pipes to ensure that the flow through the pipes is as per design

(diameter of pipe not reduced by scale).

The following work shall be carried out:

• To conduct a CCTV inspection for the penstock checking for the condition of the decanting

line prior to cleaning.

• To submit CCTV inspection footage to Employer for analysis (video and pictorial).
• The Employer shall then take a decision on the distance to clean based on the condition of

the line as evident from the video footage taken.

• To provide high pressure machine with pipework that can extend up to 500m.
• To provide water tankers for the supply of water during the high-pressure cleaning activity

‘as and when required’.

the decanting line once cleaning is completed.

4.9 Cleaning of Raw Water Reservoirs

The Employer shall carry out inspections on the reservoirs checking the extent of weeds, shrubs and

sludge that has accumulated in the reservoirs. Upon completion of the inspection, if the amount of

sludge, shrubs and weeds significantly affect the capacity and operability of the reservoirs overall,

an instruction shall then be issued to clean the reservoirs.

The following minimum actions shall be carried out by the Contractor for the execution of the works:

• To determine sludge/sediment depth on an “as and when required” basis (conduct sonar

surveys which will clearly indicate the sludge mass and water volume).

• To supply and transport all identified cleaning equipment to site as identified in the

Contractors Method Statement.

• Care is to be taken in ensuring that the base of the dam and entire wall structure is not

damaged during the cleaning.

• To ensure that existing structures (overflow spillways), water supply pipework, lighting and

all other components are not damaged during the cleaning. The Contractor shall be liable for

any damage caused to this infrastructure because of the cleaning activities.

• To ensure that the solid material is separated from the water and dried adequately.
• To remove the dried sludge/sediment by trucks to the designated dumping site.
• To clean and rehabilitate site to its original or better state.
