Curing Compound Supply for Clanwilliam Dam

The Department of Water and Sanitation (DWS), through its Construction South unit, has invited bids for the supply and delivery of liquid membrane-forming curing compound for the rehabilitation and raising of the Clanwilliam Dam on the Olifants River, approximately 2 km south-west of Clanwilliam town in the Western Cape. The works include raising the dam wall to approximately 370 m in length and 49 m in maximum height, adding concrete on the downstream side, extending the apron, and constructing a free-standing intake tower, outlet control house, power generating house, short tunnel and coffer dam works. Because the project must proceed without interfering with the dam's day-to-day operation, a reliable supply of curing materials is essential to the concrete works.

The scope of supply covers 7 units of 200-litre curing compound, which must be a heavy-duty, industrial-grade, wax-based or wax-emulsion liquid membrane-forming compound. The product must meet the performance requirements of ASTM C309 Standard Specification for Liquid Membrane-Forming Compounds for Curing Concrete, Type 1, Class A, be suitable for application by spray, brush or roller, and be supplied in the manufacturer's sealed containers with a minimum shelf life of 12 months from delivery. Packaging is preferably plastic drums. Bidders must submit technical datasheets clearly identifying the qualifying specification, and must initial and sign the technical compliance declaration in Section 3.2.14. The Department will reject non-compliant loads at the bidder's cost. Delivery must be made to the DWS Construction South site offices at Clanwilliam Dam within working hours (08:00 to 15:00), excluding weekends, public holidays, 11 December to 9 January, and the last Friday of each month. A delivery schedule must be provided within 5 working days of acceptance, and delivery must commence within 10 working days of the first order, with a seven-day delivery period after order receipt.

The contract is awarded on an 80/20 preference point system, with 80 points for price and 20 points for specific goals, including women, youth and disability ownership, Western Cape location, and B-BBEE status. Bids must be priced on an all-inclusive, firm-price basis delivered to site, with transport included, and remain valid for 120 days from closing. Payment is made monthly within 30 days of receipt of an approved tax invoice and signed delivery notes, by electronic funds transfer. Mandatory documents include the SBD 1, SBD 3.1 pricing schedule, SBD 4, SBD 6.1, CSD report, SARS tax compliance proof, CIPC registration, and B-BBEE certificate. Benefits for suppliers include a clearly defined, low-volume, short-cycle supply order within a major public infrastructure project, and a firm payment process backed by government procurement rules.
