Construction Health & Safety Specifications: The Complete Client Guide

The authoritative guide for property developers, infrastructure clients, and procurement teams on drafting baseline Health & Safety Specifications under Construction Regulation 5(1)(b).

1. The Statutory Client Mandate: Construction Regulation 5(1)(b) Explained

In South African construction procurement, awarding a contract based solely on the lowest tender price without defining safety parameters is a recipe for disaster. Contractors desperate to win bids frequently eliminate safety supervisors, cut scaffolding budgets, and bypass worker medicals to submit artificially low prices.

Under Construction Regulation 5(1)(b) of the Occupational Health and Safety Act (Act 85 of 1993), the law places the initial duty squarely on the Client (the property owner, infrastructure fund, or corporate developer).

The client must prepare a comprehensive, site-specific Baseline Health and Safety Specification and include it in all tender documentation. Furthermore, under Regulation 5(1)(g), the client must ensure that potential principal contractors have made adequate financial provision for health and safety measures before awarding any contract.

2. The 8 Core Sections of an Audit-Ready Client Safety Specification

A compliant Client Health and Safety Specification establishes the baseline contractual rules governing the site across eight essential sections:

The 8 Core Sections of a Client Health & Safety Specification

Specification SectionScope & Technical FocusClient Baseline RequirementContractor Pricing Obligation
1. Project Scope & Site DescriptionGeographical boundaries, existing buildings, traffic constraints.Site plan, working hours, access security rules.Site establishment, security perimeter, hoarding costs.
2. Geotechnical & Environmental HazardsSoil stability, water table, contaminated ground, silica dust.Geotechnical borehole logs, soil classification data.Shoring boxes, dewatering pumps, dust suppression.
3. Existing Services & WayleavesUnderground electric cables, gas mains, overhead powerlines.Municipal wayleave drawings, live service locations.Cable avoidance tools (CAT/Genny), potholing crews.
4. Designer Risk Assessment (CR 6)Structural loading limits, specialized temporary works.Engineer's constructability assumptions report.Engineered propping, structural monitoring gear.
5. Statutory Appointments & PersonnelSACPCMP CHSO, Construction Manager (CR 8.1), First Aiders.Mandatory qualification and experience minimums.Full-time qualified safety officer salaries.
6. High-Risk Operational ControlsWorking at Heights (CR 10), Scaffolding (CR 16), Cranes (CR 23).Site-specific Fall Protection Plan & lift plans.Certified full-body harnesses, Scafftags, LMI load tests.
7. Occupational Health & MedicalsNoise, vibration, chemical agents, fitness certificates.Annexure 3 medical surveillance protocols.Pre-placement, periodic, and exit medical examinations.
8. Health & Safety Budget ScheduleItemized pricing schedule for all safety deliverables.Mandatory standalone section in Bill of Quantities.Detailed line-item pricing for every safety compliance item.
Statutory components of a baseline specification under Construction Regulation 5.

3. Tender Evaluation: Enforcing Itemized Health & Safety Pricing

A major compliance failure in construction procurement is allowing contractors to price health and safety as a single, lump-sum percentage (e.g. '1% for Preliminaries & Generals').

Under CR 5(1)(g), the client must evaluate whether the contractor has allocated real, realistic financial resources for safety. The tender must contain a dedicated Itemized Health and Safety Bill of Quantities with separate line items for: Full-time SACPCMP Safety Officer salary, Medical Certificates of Fitness, PPE replenishment, Scaffolding weekly inspections, Lifting machine load testing, and Certified training courses.

If a contractor submits a zero or unrealistic safety budget, the client has a statutory duty to disqualify the bid or demand price adjustment.

4. Integrating Designer Risk Assessments (CR 6) into the Specification

Under Regulation 5(1)(c), the client must ensure that the designer's safety inputs are embedded directly into the baseline specification.

The consulting structural and civil engineers must supply the Designer Risk Assessment Report, highlighting design-specific risks: post-tensioned slab cutting hazards, heavy precast panel erection sequences, or hazardous architectural coatings.

By including designer risk assessments in the tender specification, the client ensures that bidding contractors price the specialized cranes, propping systems, and rigging crews required for safe structural execution.

5. 5-Stage Client Specification & Tender Procurement Roadmap

01
Appoint SACPCMP Pr.CHSA Client Safety Agent (CR 5.5)

Designate a registered Professional Safety Agent during the project inception and feasibility phase.

02
Gather Geotechnical, Service & Designer Risk Data

Collect borehole logs, municipal utility wayleaves, and structural engineer constructability risk reports.

03
Draft the Comprehensive 8-Section Baseline H&S Specification

Compile site-specific rules, mandatory personnel requirements, and the itemized safety Bill of Quantities.

04
Issue Specification in Tender Dossier & Evaluate Bids

Issue specification to bidding contractors and audit submitted safety budgets against statutory benchmarks.

05
Audit & Approve Principal Contractor Health & Safety Plan (CR 7)

Review and approve the winning contractor's site-specific safety plan in writing before site handover.

6. Client Health & Safety Specification Verification Checklist

  • Baseline H&S Specification is 100% site-specific and signed by an appointed SACPCMP Pr.CHSA agent.
  • Specification is embedded in all tender dossiers and construction contract documents.
  • Geotechnical borehole reports and municipal underground utility wayleaves are attached as Annexures.
  • Designer Risk Assessment Report from consulting structural engineers is integrated under CR 6.
  • Bill of Quantities contains a dedicated, itemized Health & Safety Pricing Schedule.
  • Winning contractor's Health and Safety Plan is reviewed and approved in writing prior to site handover.
  • Monthly client health and safety audits are scheduled and budgeted throughout the construction phase.

Frequently Asked Questions

Is preparing a Health and Safety Specification legally mandatory for all construction clients?

Yes. Under Construction Regulation 5(1)(b), every client must prepare a site-specific baseline health and safety specification for any construction project, regardless of whether it is a private commercial building or a public infrastructure project.

Can a client just tell the contractor to 'comply with the OHS Act' in the tender?

No. Broad, vague clauses stating 'the contractor must comply with the OHS Act' are legally rejected. The specification must be a site-specific risk assessment detailing actual ground conditions, adjacent hazards, and project rules.

Who must draft the Client Baseline Safety Specification?

The specification should be drafted by a registered SACPCMP Professional Construction Health and Safety Agent (Pr.CHSA) appointed by the client to represent their statutory interests.

What happens if a contractor submits a tender with zero safety budgeting?

Under CR 5(1)(g), the client has a legal duty to verify that the contractor has made adequate financial provision for safety. If safety budgeting is absent or inadequate, the client cannot legally award the contract.
