Objectives

The primary objective is to execute comprehensive waterproofing refurbishments across the Themba Kojana Office Park in Aliwal North, Eastern Cape. The project aims to restore and enhance the structural integrity of roofing, drainage, and waterproofing systems across five interconnected buildings within a six-month contract period, while adhering to public sector procurement standards, occupational health and safety regulations, and local economic development targets.

Scope of Work

The scope encompasses repairs and renovations to existing waterproofing systems across designated building wings. Key activities include:

• Removal and replacement of roof sheeting, flashings, cappings, valleys, and gutters.
• Core drilling through gutters and roof slabs, followed by installation of new downpipes, stormwater outlets, and rainwater systems.
• Application of new waterproofing coatings and systems on roofs, screeds, and structural elements.
• General refurbishment works related to drainage channels and associated accessories.

All works must align with approved architectural drawings, bills of quantities, and a project-specific methodology detailing sequencing, timelines, and resource allocation for each wing.

Technical Requirements

• Contractual Framework: Governed by a standard South African construction agreement model that outlines rights, obligations, payment mechanisms, and dispute resolution procedures.
• Grading & Registration: Contractors must hold a national construction industry grading of at least Grade 4GB (Class GB) and maintain active registration on the government supplier database with SARS tax compliance.
• Health & Safety: Strict adherence to national occupational health and safety legislation is mandatory. A detailed health and safety plan must be submitted within fifteen working days of contract award. All personnel require valid police clearance certificates issued within fifteen days of site commencement. Personal protective equipment and predetermined site identification overalls are compulsory.
• Quality & Planning: Submission of a project-specific quality management plan, construction work programme, and baseline risk assessment is required. The programme must detail deliverables, dependencies, and resource optimization for each building wing.
• Financial & Preference Criteria: Evaluation follows an 80/20 preference point system (80 points for price, 20 points for specific goals such as historically disadvantaged individual ownership, Eastern Cape locality, and other transformation targets). A current bank rating letter demonstrating financial capacity is required. The defects liability period is extended to 365 calendar days.
• Site Constraints: Works must occur between 07:00 and 17:00 daily, including weekends. The site is high-security; contractors cannot store materials outside designated builders’ yards and must comply with strict access control protocols.

Skills and Personnel Requirements

Tenderers must demonstrate adequate expertise through key personnel submissions:

• Project Manager: Must hold a Built Environment qualification (B-Tech or BSc) and possess a minimum of five years’ post-qualification experience.
• Health and Safety Officer: Requires professional registration with the national project and construction management council and a Built Environment qualification (N Diploma), alongside five years’ post-qualification experience.
• Site Agent: Must hold a Built Environment qualification (N Diploma) and have at least three years’ post-qualification experience.

All proposed key personnel must commit to attending all technical and progress site meetings throughout the project duration. Additionally, subcontractors engaged for specialist trades must be nationally graded, supplier-database compliant, and capable of delivering similar waterproofing or roofing projects valued at R2 million or more. The contractor must also provide evidence of available artisans, foremen, quality control personnel, and labour resources.

Key Terminology Explanation

JBBC Principal Building Agreement: A widely used South African standard form of contract that defines the legal relationship, payment terms, variations, and dispute resolution processes between employers and contractors.
