Tender Summary: Supply and Install Epoxy Flooring in the FD Utility Area

Objectives

The primary objective is to supply and install a high-performance, chemically resistant epoxy flooring system across a 200 m² utility area housing critical freeze-drying and vacuum equipment. The project aims to extend floor lifespan, maintain strict environmental and cleanliness standards, isolate machinery vibrations, and ensure full compliance with national procurement and construction regulations.

Scope of Work

The successful bidder will execute a complete floor renovation cycle, including:

• Site Survey & Mapping: Document exact physical clearances, pipe configurations, anchor bolts, and structural bases of immovable equipment.
• Asset Protection: Shield machinery frames, electrical cabinets, and piping using heavy-duty plastic sheeting and solvent-resistant masking tape.
• Environmental Controls: Implement strict dust containment to protect mechanical components and cleanroom-adjacent zones.
• Surface Preparation: Mechanical grinding, edge/under-equipment detailing, stain decontamination, and crack/spall patching.
• Vibration Isolation & Joint Interfacing: Cut perimeter chase lines around equipment bases and fill with flexible sealant to prevent coating fracture.
• Coating Application: Apply primer, base coat, and polyurethane topcoat layers according to manufacturer specifications.
• Post-Application & Cleanup: Remove protective materials after curing and dispose of all chemical, dust, and installation waste.

Technical Requirements

• System Type: High-build, 100% solids, low-VOC/solvent-free industrial epoxy floor system.
• Thickness: 1–2 mm (high-build) or 2–3 mm (self-levelling), adjusted to facility mechanical load requirements.
• Primer: Low-viscosity, moisture-tolerant epoxy applied at manufacturer-recommended rates to seal substrate and prevent outgassing.
• Base Coat: Self-levelling or high-build epoxy applied via notched squeegees and hand-trowels, with spike shoes for tight clearances.
• Topcoat: Chemical-resistant polyurethane finish; anti-slip aggregate broadcast if wet washdowns are routine.
• Surface Profile: Achieve Concrete Surface Profile (CSP) 2–3 using planetary diamond grinders paired with HEPA-filtered vacuums.
• Compliance & Documentation: Valid CIDB registration (Grade 01 GB or higher), completed SBD4 declaration, Central Supplier Database (CSD) registration, three traceable reference letters (≤36 months), and manufacturer data sheets for the proposed epoxy system.
• Evaluation Model: 80/20 weighted scoring (80% price, 20% socio-economic preference per Preferential Procurement Framework Act).

Skills & Qualifications Requirements

• Proven experience installing industrial epoxy flooring in pharmaceutical, biological, or utility environments.
• Proficiency in precision concrete grinding, dust containment protocols, and surface profiling to CSP standards.
• Expertise in vibration isolation techniques, including perimeter chasing and elastomeric joint sealing.
• Ability to operate safely in restricted clearances around sensitive machinery without causing damage or cross-contamination.
• Familiarity with South African construction grading, BBBEE certification verification, and standard bid documentation (SBD forms).

Specialised Terms & Clarifications

• Concrete Surface Profile (CSP) 2–3: An industry-standard metric measuring concrete roughness; this range ensures optimal mechanical bonding for epoxy coatings without excessive material consumption.
• Elastomeric Sealing: Use of flexible, stretchable polyurethane or polymer sealants at equipment interfaces to absorb operational vibrations and prevent rigid floor coatings from fracturing.
• HEPA Filtration: High-Efficiency Particulate Air systems used during grinding to capture microscopic dust particles, critical in biological/pharmaceutical facilities to prevent airborne contamination.
• 80/20 Preference System: A South African public procurement scoring model allocating 80% of evaluation points to competitive pricing and 20% to socio-economic transformation goals (e.g., black/women ownership, disability status), verified through valid BBBEE certificates and official declarations.
