Objectives

The primary objective of this tender is the construction of a durable, reinforced concrete road section on Madonya Road in Ward 17. The project aims to upgrade local infrastructure by delivering a properly graded, drained, and paved roadway that meets municipal engineering standards and improves community accessibility.

Scope of Work

• Site Clearance: Complete clearing and grubbing of the road reserve, including removal of vegetation, debris, and unsuitable materials.
• Earthworks & Roadbed Preparation: Excavation, cut-and-fill operations, and compaction of the subgrade to specified densities, including a 150 mm undercut where necessary.
• Concrete Pavement: Construction of a 100 m long, 5 m wide, 150 mm thick reinforced concrete road surface.
• Drainage: Construction of a single-sided V-drain (100 m length, 1 m width, 330 mm depth) with a 150 mm thick concrete lining shaped for proper water runoff.
• Joints & Finishing: Installation of contraction and expansion joints at prescribed intervals, sealing with approved compounds, and application of a broom finish for skid resistance.
• Curing & Handover: Minimum seven-day curing period, followed by final inspections and project handover within six weeks of award.

Technical Requirements

• Material Specifications: Pavement concrete must achieve 25 MPa compressive strength with a slump of 75–100 mm and maximum 19 mm aggregate. Drainage lining requires 20 MPa concrete. Reinforcement must utilise Ref 193 welded steel mesh placed at mid-slab depth with minimum 300 mm overlaps.
• Compaction Standards: Subgrade must be proof-rolled and compacted to 95% Modified AASHTO density. Fill layers require 93% Modified AASHTO density.
• Quality Control & Tolerances: Mandatory submission of batch plant delivery notes and test results. Engineer inspections required before concrete pours. Strict tolerances apply: surface level ±10 mm, thickness -5/+10 mm, alignment ±10 mm.
• Regulatory Compliance: Works must comply with the Occupational Health and Safety Act, Compensation for Occupational Injuries and Diseases Act, General Conditions of Contract (2015, 3rd Edition), SANS 1200, COTO Standard Specifications, and SABS material standards.
• Health & Safety: Contractor must submit an approved Health and Safety file, provide PPE, safety signage, traffic management plans, and appoint competent personnel.
• Pricing & Validity: All Bill of Quantities items must be priced inclusively (labour, plant, materials, transport, wastage, testing). Quotations must remain valid for 120 days.
• Mandatory Documentation: Valid tax pin, company registration, B-BEE certificate or sworn affidavit, VAT registration (if applicable), signed quotation on company letterhead, CSD registration summary, proof of residence, and CIDB grading certificate (minimum 1 CE).

Skills and Experience Requirements

• Contractor Classification: Minimum CIDB Grading 1 CE (Earthworks and Drainage) certification is mandatory.
• Project Track Record: Bidders must provide evidence of completed concrete road construction projects. Functionality scoring awards up to 10 points for five or more projects, verified through appointment letters and completion certificates.
• Key Personnel: CVs for a foreman, technician, or site agent must be submitted, demonstrating direct experience in concrete road construction. Points are allocated based on years of relevant experience (one to five-plus years).
• Evaluation Criteria: Contracts will be adjudicated based on relevant specifications, value for money, execution capability, and compliance with the Preferential Procurement Policy Framework Act (PPPFA).

Notes on Technical Terms

• Modified AASHTO Density: A standardised laboratory compaction test used in civil engineering to determine the optimal moisture content and maximum dry density of soils, ensuring a stable, load-bearing road foundation.
• COTO Standard Specifications: Guidelines published by the Council for Toll Roads, widely adopted across South Africa for road design, construction methodology, and quality assurance.
• PPPFA: The Preferential Procurement Policy Framework Act, South African legislation requiring public entities to factor in socio-economic transformation goals, particularly black economic empowerment, during procurement processes.
• CIDB 1 CE Grading: A foundational contractor classification issued by the Construction Industry Development Board, authorising firms to undertake earthworks and drainage projects up to a defined financial threshold.
• CSD Registration: The Central Suppliers Database, a mandatory national registry for all vendors supplying goods or services to South African government entities and municipalities.
