Objectives

The primary objective is to construct a reinforced concrete road section along Chiliza Road in Ward 8, including associated earthworks, drainage infrastructure, and site preparation. The project aims to deliver a durable, compliant roadway within a strict six-week completion period while adhering to municipal standards, health and safety legislation, and preferential procurement regulations.

Scope of Work

• Site Clearance: Clear and grub the entire road reserve, removing vegetation, debris, and unsuitable materials.
• Roadbed Preparation: Excavate a 150 mm undercut, proof-roll, compact in-situ material to 95% Modified AASHTO density, and shape to the required profile.
• Concrete Pavement: Construct a 100 m long, 5 m wide, 150 mm thick reinforced concrete road using 25 MPa grade concrete.
• Reinforcement & Joints: Install Ref 193 welded mesh at mid-depth with minimum 300 mm laps. Form contraction joints at 3–5 m intervals and seal all joints with approved sealant.
• V-Drain Construction: Build a 100 m long, 1 m wide, 330 mm deep V-drain on one side, lined with 150 mm thick 20 MPa concrete.
• Curing & Finishing: Cure concrete for a minimum of seven days and apply an F2 broom finish for skid resistance.

Technical Requirements

• Standards Compliance: All works must comply with SANS 1200, COTO Standard Specifications, and SABS material standards.
• Quality Control: Provide batch plant test results and delivery notes confirming concrete strength. Engineer inspection is mandatory prior to concrete pouring. Strict tolerances apply: surface level ±10 mm, thickness -5/+10 mm, alignment ±10 mm.
• Health & Safety: Full compliance with the Occupational Health and Safety Act. Contractors must submit a Health and Safety file, provide PPE, safety signage, and implement traffic management plans.
• Pricing & Validity: All Bill of Quantities items must be priced inclusively (labour, plant, materials, transport, wastage, testing). Quotations must remain valid for 120 days.
• Completion Period: Six weeks from the date of contract award.

Skills & Experience Requirements

• Company Experience: Bidders must demonstrate past performance in concrete road construction. Points are allocated based on the number of completed projects (proof via appointment letters and completion certificates required).
• Key Personnel: A foreman, technician, or site agent with verifiable experience in concrete road construction is mandatory. Experience thresholds range from over five years down to one year, with corresponding scoring.
• Registration & Compliance: Mandatory registration on the Central Suppliers Database (CSD), CIDB grading 1CE, valid B-BBEE certificate, tax pin sheet, company registration documents, and proof of residence.
• Preferential Procurement: Evaluation follows an 80/20 or 90/10 point system favoring price and specific goals, including 100% black-owned EMEs/SMEs and enterprises located within the municipality or KwaZulu-Natal province.
• Exclusions: Bids from individuals or entities currently in the service of the state will not be considered.

Notes on Specialized Terms

• Modified AASHTO Density: A standardized laboratory compaction test used in civil engineering to determine the maximum dry density and optimum moisture content of soils, ensuring adequate load-bearing capacity for road foundations.
• SANS 1200 & COTO: South African National Standards for civil engineering construction and the Committee of Transport Officials’ standard specifications, respectively. They dictate material properties, construction methods, and quality benchmarks.
• F2 Surface Finish: A concrete finishing specification requiring a textured broom finish to enhance skid resistance and safety for vehicular traffic.
• PPPFA (80/20 or 90/10 System): A preferential procurement framework where up to 80 or 90 points are awarded for competitive pricing, and the remaining 10 or 20 points are allocated for socio-economic goals such as black ownership and local economic development.
