Road Maintenance and Slurry Seal Repairs

Sentech SOC Limited is seeking a qualified civil contractor to carry out maintenance and restoration of the tarred access road serving its Welverdiend T96 site near Carletonville, Gauteng. The road is approximately 2.2 km long and 3.5 m wide, and has deteriorated through potholes, edge breaks and grass growing through the surface. The appointed provider will be responsible for the full repair programme, from site establishment and road condition assessment through to final slurry sealing and handover. The work must be completed within a maximum of 30 working days.

The scope of work includes removal of grass including roots, followed by herbicide treatment to prevent regrowth; sawing and patching of affected asphalt (not exceeding 50 mm); pothole patching; repair of edge breaks; and supply and application of fine slurry seal 3 to 6 mm thick when dry. The slurry is to use 2 to 4.7 mm crusher dust aggregate, cement or lime filler, and a quick-setting cationic emulsion. All work must comply with TRH3 (2007) Design and Construction of Surfacing Seals and applicable SABS standards, and all materials must be SABS approved. Contractors must supply their own temporary facilities, portable toilet, power, food and water, and may not subcontract any work. A demonstration or sample slurry application must be approved on site before full application begins, and quality inspections are held at defined milestones. Rubble and waste must be removed from site, and a one-year warranty on materials and workmanship applies. Health and safety requirements include a health and safety file, medical fitness certificates for all workers, public liability insurance and COIDA registration. A detailed bar-chart execution schedule must accompany the quotation.

To be considered, bidders must hold a valid CIDB grading of 2CE or higher, a valid COIDA letter of good standing aligned with the scope of work, and tax compliance, and must be registered on the Sentech Supplier Database. Quotations must be on company letterhead, completed and signed in black ink, and submitted by email to Quotations4@sentech.co.za before 12:00 on 11 November 2026, with copies sent to SCM as directed in the special conditions. Attendance at the compulsory site briefing on 3 November 2026 at 11:00 is required. Functional evaluation carries 60 points, with a minimum of 40 required, based on completed road repair projects supported by reference letters or completion certificates. Price and preference are scored on an 80/20 basis, with B-BBEE certificates required to claim preference points. Quotations remain valid for 90 days. Sentech reserves the right to negotiate prices and to appoint one or more suppliers, in whole or in part, or not at all.
