Objectives

The primary objective is the timely delivery of a 100-metre reinforced concrete road section along Esindlovini Road in Steephill, Ward 18. The project aims to upgrade local infrastructure, improve accessibility, and ensure compliance with municipal engineering standards, occupational health and safety legislation, and sustainable construction practices. The contract must be completed within six weeks of award.

Scope of Work

The contractor will execute a comprehensive range of civil engineering works, including:

• Site Clearance: Clear and grub the entire road reserve, removing vegetation, debris, and unsuitable material.
• Roadbed Preparation: Excavate a 150 mm undercut, proof-roll the subgrade, replace unsuitable soils, and compact in-situ material to 95% Modified AASHTO density.
• Concrete Pavement: Construct a 150 mm thick, 25 MPa grade concrete slab measuring 100 m in length and 5 m in width. Works include formwork installation, concrete placement, poker vibration, and a broom-finish surface for skid resistance.
• Reinforcement: Install Ref 193 welded steel mesh at mid-depth of the slab with minimum 300 mm laps.
• Joints & Curing: Form contraction joints at 3–5 m intervals and expansion joints where necessary, seal with approved compound, and cure for a minimum of seven days.
• Drainage: Construct a single-sided V-drain (100 m long, 1 m wide, 330 mm deep) with a 150 mm thick concrete lining, shaped for proper drainage and tied into the road edge.
• Earthworks: Execute cut-and-borrow fill operations, compact fill layers to 93% Modified AASHTO density, and remove soft and hard excavation spoil within a 1 km free-haul distance.

Technical Requirements

All works must adhere to SANS 1200 and the latest COTO Standard Specifications. The project is governed by national legislation, including the Occupational Health and Safety Act, Construction Regulations, Compensation for Occupational Injuries and Diseases Act, Income Tax Act, Value Added Tax Act, and the Municipal Finance Management Act. The contract follows the General Conditions of Contract (GCC) 2015, 3rd Edition.

Quality control mandates batch plant delivery notes, compressive strength test results, pre-pour engineer inspections, and rigorous level/thickness verification. Dimensional tolerances are strictly enforced: surface level and alignment at ±10 mm, and thickness between -5 mm and +10 mm. Pricing must be all-inclusive per Bill of Quantities item, covering labour, plant, materials, transport, wastage, overlaps, and testing. Bids require mandatory documentation, including valid tax pin sheets, company registration and director IDs, B-BBEE certificates or sworn affidavits, VAT registration (if applicable), Central Suppliers Database proof, proof of residence, and a minimum CIDB grading of 1 CE. Quotations must remain valid for 120 days.

Skills and Experience Requirements

Bidders must demonstrate proven capability in civil infrastructure delivery. Evaluation awards points based on the number of successfully completed concrete road projects, with a minimum of two projects required for baseline scoring. Detailed appointment letters, completion certificates, or reference letters must accompany the bid.

The appointed site management team—including a foreman, technician, or site agent—must possess verifiable experience in concrete road construction. Points are allocated according to years of relevant experience, supported by attached CVs. Overall adjudication considers technical capability, value for money, financial stability, and compliance with preferential procurement regulations.

Key Terminology and Special Conditions

• CSD Registration: The Central Suppliers Database is the official South African government vendor registry. Submission of a CSD summary report is mandatory for bid eligibility.
• CIDB Grading 1 CE: The Construction Industry Development Board’s entry-level classification for civil engineering contractors, confirming foundational competency in small-scale infrastructure projects.
• Modified AASHTO Density: A standardized compaction test method used to verify soil and base layer density, ensuring structural load-bearing capacity.
• PPPFA Compliance: The Preferential Procurement Policy Framework Act dictates that 80% of evaluation points are awarded on price and 20% on broad-based black economic empowerment (B-BBEE) status.
• GCC 2015: The standard South African public sector construction contract template outlining payment terms, risk allocation, variation procedures, and dispute resolution mechanisms.
