When a plant shuts down, every hour of delay carries a financial consequence. For procurement officers and project managers at industrial facilities across South Africa, the single most effective tool for controlling scaffolding costs, timelines, and safety outcomes is a well-written scope of work (SOW), issued before the first RFQ goes out.

Pro Rise Scaffolding, based in Johannesburg, South Africa, works with procurement and HSE teams at refineries, food processing plants, chemical facilities, and manufacturing operations nationwide. In our experience, a thorough scaffolding SOW is what separates a shutdown that runs on schedule from one that bleeds time and money through scope changes, variation orders, and safety non-conformances.

This guide covers every element a scaffolding SOW must include, the most common mistakes procurement officers make, how to specify B-BBEE requirements, and what to look for when evaluating contractor quotes.

Why the SOW Is the Foundation of Shutdown Success

Industrial shutdown scaffolding is not a commodity purchase. Unlike buying consumables or standard equipment, scaffolding access requirements change with every plant, every unit, and every maintenance scope. A vague or incomplete SOW produces quotes that are incomparable, one contractor prices a system scaffold solution while another prices tube-and-fitting, and a third allows for inadequate load ratings. None of the three quotes reflects the same project.

The consequences of a poor SOW are predictable:

  • Scope creep: Contractors discover work areas mid-shutdown that were not in the original scope, triggering variation orders at premium rates.
  • Safety non-conformances: Without specified compliance requirements, contractors may erect structures that do not meet SANS 10085-1:2024 or the Construction Regulations of 2014 under the Occupational Health and Safety Act (Act 85 of 1993).
  • Schedule overruns: An ill-defined demobilisation requirement can leave scaffold standing on live plant after the shutdown window closes, creating both safety and productivity risks.
  • Disputed invoices: Without defined inspection and tagging regimes in the SOW, contractors and clients disagree on what "handed over" means.

A detailed SOW eliminates these failure modes before they start. It also gives contractors the information they need to price accurately, which means the quotes you receive reflect the actual work, and you can compare them on a like-for-like basis.

The 8 Sections Every Scaffolding SOW Must Include

1. Project Description and Location

The SOW must open with a clear statement of the facility, its location, the nature of the shutdown or maintenance event, and the planned access period. Include the plant name, address, the unit or units being shut down, and any site-specific access or PPE requirements visitors must meet before arriving on site.

For multi-site operations, for example, a Gauteng-based head office coordinating a shutdown at a Richards Bay facility, specify the facility address separately. Contractors price mobilisation differently depending on distance and logistics.

2. Scope of Access: Work Areas and Elevation Ranges

This is the most critical section of the entire document. For each work area, specify:

  • Location description (e.g., "Distillation Column 3, North Face, Elevation 6m–22m")
  • Access type required (working platform, inspection access, maintenance access)
  • Approximate scaffold footprint in square metres where known
  • Any confined space or restricted-access considerations

Where possible, attach plant layout drawings or isometrics. Contractors who receive a clearly defined work area list can price more accurately than those left to interpret a generic "all process areas" instruction.

3. Scaffold System Type Required

The SOW must state which scaffold system is appropriate for the work. Common options in South African industrial environments include:

  • System scaffold (ringlock, cuplock): preferred for heavy industrial applications with regular load and geometry
  • Tube-and-fitting scaffold: required for complex geometries, pipe bridges, and confined access areas
  • Mobile access towers: suited for light maintenance access at fixed heights

If the client does not specify a system, contractors will choose based on cost or availability, not necessarily the best fit for the application. Where the client has a site standard or preference, state it explicitly.

4. Load Requirements

Under SANS 10085-1:2024, scaffolds are classified by load capacity. The SOW must specify:

  • The working load class required (light duty, medium duty, heavy duty, or special loading)
  • Any point loads from equipment, pipe spools, or materials staged on the scaffold deck
  • Whether the scaffold must support personnel only, or personnel plus equipment and materials simultaneously

Failure to specify load requirements is one of the most common SOW omissions, and one of the most dangerous. A scaffold erected for inspection access (light duty) is not safe for heavy maintenance work without reclassification and re-inspection.

5. SANS 10085 Compliance Requirements

South Africa's scaffolding standard, SANS 10085-1:2024 (The design, erection, inspection, use, modification and dismantling of steel tube and coupling scaffolding), sets the legal framework for all scaffold erection and inspection work. The SOW must state explicitly that all scaffolding work is to comply with SANS 10085-1:2024 and the Construction Regulations of 2014.

Refer to the Pro Rise guide to SANS 10085 scaffolding regulations for a detailed breakdown of the standard's key compliance requirements.

Key compliance clauses to reference in the SOW include:

  • All scaffolding must be designed by a competent person where it exceeds specified height thresholds
  • No trestle ("bokkie") scaffolding or non-compliant frame scaffolding permitted on site
  • All scaffolding must be erected and dismantled under the supervision of a scaffold team leader holding a valid competency certificate

6. Personnel Competency Requirements

Under Section 16 of the Construction Regulations, the contractor must appoint, in writing, a competent person to supervise all scaffolding operations. The SOW should specify:

  • Scaffold team leader certification (e.g., TETA-accredited or equivalent)
  • Scaffold erector competency requirements
  • Whether a dedicated scaffold inspector is required on site (strongly recommended for shutdowns with multiple simultaneous work fronts)
  • First-aid and Working at Heights competency requirements for all scaffold personnel

Requiring proof of competency at the RFQ stage separates capable contractors from those who cannot meet the standard.

7. Inspection and Tagging Regime

The SOW must define the inspection and tagging protocol. In South African industrial practice, the standard colour-coded scaffold tag system uses:

  • Green tag: scaffold is safe for use and has been inspected
  • Yellow tag: scaffold may be used with specified restrictions
  • Red tag: scaffold is not safe for use, access prohibited

The SOW should specify:

  • Frequency of scaffold inspections (typically before each work shift and after any event affecting structural integrity)
  • That inspection records must be retained and made available to the client's HSE representative on request
  • That scaffold tags must be current at all times, signed by the inspecting competent person
  • Who is responsible for changing tag status (contractor's inspector, or a joint client-contractor sign-off)

8. Demobilisation Requirements

An industrial shutdown has a fixed window. The SOW must define:

  • The expected demobilisation date and any penalty provisions for late removal
  • The standard to which the area must be left after scaffold removal (e.g., "all scaffold materials removed from the plant, area swept clean of scaffold pins and clips")
  • The process for client sign-off on completed demobilisation
  • Any requirements for progressive demobilisation as work areas complete, rather than a single final removal

Clear demobilisation terms protect the plant operator and give the contractor a defined scope of work for the back end of the shutdown.

How to Specify B-BBEE Requirements in a Scaffolding Contract

The scaffolding contract or tender document must include B-BBEE requirements as a scored criterion, not an afterthought. Key provisions to include:

  • Minimum B-BBEE level: State the minimum acceptable B-BBEE contributor level (e.g., "suppliers must hold a valid B-BBEE Level 1 or Level 2 certificate issued by an accredited verification agency, or a sworn affidavit for qualifying EME or QSE entities").
  • Subcontracting provisions: If the contractor intends to subcontract any portion of the work, state that subcontractors must also meet the minimum B-BBEE requirement.
  • Certificate currency: Require that the B-BBEE certificate or affidavit be current at the time of quotation and at contract commencement.
  • Procurement recognition level: Under Statement 400 of the B-BBEE Codes of Good Practice, spend with a BEE Level 1 supplier counts at 135% on the client's preferential procurement scorecard, versus 100% for a Level 4 supplier. Factor this difference into the scoring matrix.

For companies operating under the Mining Charter 2018, the Amended Construction Sector Code (Gazette 41287, December 2017), or the requirements of state-owned entities, BEE compliance may carry additional sector-specific targets and weight. Confirm which codes apply to your procurement context before issuing the RFQ. You can review the legal framework for scaffolding in South Africa for further context on regulatory obligations.

Common Mistakes Procurement Officers Make in Scaffolding RFQs

Even experienced procurement teams make predictable errors in scaffolding RFQs. These are the most damaging:

1. Vague scope descriptions.
"Supply and erect scaffolding as required for maintenance" is not a scope. It produces a range of quotes that reflect each contractor's assumptions about the work, not the actual requirement. Contractors price risk into vague scopes, the price you receive is higher than it needs to be, and the risk of variations increases.

2. Missing safety specifications.
Omitting the SANS 10085 compliance requirement and competency requirements from the RFQ allows contractors to submit quotes that do not account for compliant inspection, tagging, and personnel costs. When those requirements are applied on site, the actual cost escalates.

3. No inspection schedule.
An RFQ that does not specify the inspection and tagging regime invites shortcuts. Scaffold inspections are a cost item, they require a competent, dedicated person. Contractors who have not priced for a full inspection regime will not provide one unless contractually required.

4. Not specifying erection methodology.
For complex industrial environments, columns, pressure vessels, pipe bridges, the erection methodology matters for both safety and schedule. A contractor who plans to erect tube-and-fitting freestanding scaffold cannot be compared fairly with one who plans a tied system scaffold. Specify the methodology, or require contractors to submit their proposed methodology with the quote.

5. No demobilisation provision.
Procurement teams often focus entirely on erection and forget to define the removal scope. Demobilisation costs are real and should be priced transparently in every quote.

How to Evaluate and Compare Scaffolding Quotes Against the SOW

Once quotes arrive, a structured evaluation matrix ensures you compare like with like. Evaluate each quote across the following criteria:

  • SOW compliance: Has the contractor addressed every section of the SOW, or are there gaps in their response?
  • Pricing structure: Is the quote itemised by work area? Lump-sum quotes for shutdown work are a red flag, they make variation management difficult.
  • Safety documentation: Has the contractor provided a site-specific method statement, risk assessment, and proof of SANS 10085 compliance?
  • Competency evidence: Has the contractor provided CVs or certificates for the nominated team leader and inspector?
  • B-BBEE documentation: Is a current, valid certificate or affidavit included?
  • Mobilisation and demobilisation timeline: Does the contractor's schedule align with the shutdown window?

A quote that addresses all six criteria at a higher price is typically lower-risk, and lower total cost, than the cheapest quote that leaves several criteria unaddressed.

The Value of a Pre-RFQ Site Assessment

The most effective intervention a procurement team can make before issuing a scaffolding RFQ is a pre-assessment site visit with the appointed (or prospective) scaffolding contractor. During this visit, the contractor walks the plant, identifies access requirements, assesses ground conditions, checks for live services or restricted zones, and documents the work areas that need to be covered.

This produces several benefits:

  • The SOW is grounded in site reality, not desktop assumptions
  • The pricing is more accurate, which means fewer variations during the shutdown
  • The contractor can raise any H&S concerns before the shutdown begins, not during it
  • The client gains confidence in the contractor's competence before work starts

Frequently Asked Questions

What is a scaffolding scope of work?
A scaffolding scope of work is a formal document issued by the client that defines every aspect of the scaffolding requirement for a project or shutdown: the work areas, scaffold types, load requirements, safety compliance standards, inspection regime, and demobilisation terms. It is the basis on which contractors price their quotes.

Why do industrial shutdowns need a detailed scaffolding SOW?
Industrial shutdowns have fixed windows, compressed schedules, and high penalties for delay. A vague scaffolding scope creates variation orders, schedule conflicts, and safety non-conformances that directly affect the shutdown's cost and timeline. A detailed SOW prevents all three.

What does SANS 10085 require for scaffolding in South Africa?
SANS 10085-1:2024 is South Africa's mandatory code of practice for the design, erection, inspection, use, modification, and dismantling of scaffolding. It requires scaffolds to be designed and supervised by a competent person, prohibits non-compliant frame and trestle scaffold types in industrial settings, and mandates a formal inspection and tagging regime. All scaffolding at industrial facilities must comply with this standard.

How do I specify B-BBEE requirements in a scaffolding RFQ?
State the minimum acceptable B-BBEE contributor level in the RFQ, require a current and valid certificate or sworn affidavit from all tenderers, apply the B-BBEE procurement recognition level as a scored criterion in the evaluation matrix, and include subcontracting B-BBEE provisions if subcontracted work is anticipated.

How many quotes should I get for shutdown scaffolding?
For significant industrial shutdown scaffolding work, a minimum of three comparable quotes from contractors who have completed the site walk and responded to the same detailed SOW is standard practice. Quotes received without a site visit or without a full SOW response are not comparable and should be treated with caution.

Can a procurement officer write a scaffolding SOW without prior scaffolding knowledge?
Yes, with the right support. The most effective approach is to conduct a pre-RFQ site walk with a qualified scaffolding contractor who can translate maintenance requirements into access specifications. That site-walk output forms the basis of the SOW, which the procurement officer then formalises into the tender document.

What is the difference between a scaffolding RFQ and a scaffolding tender?
In South African procurement practice, an RFQ (Request for Quotation) is typically used for lower-value or repeat engagements with pre-approved suppliers. A tender (or RFP) is used for larger, more complex engagements requiring a structured evaluation process. For significant industrial shutdown scaffolding, a formal tender with scored evaluation criteria, including B-BBEE, safety, and methodology, is appropriate.

Get the Scaffolding Access Right Before Your Next Shutdown

A well-written scaffolding scope of work is one of the cheapest risk-management tools available to any industrial procurement team. The time invested in a thorough SOW before the RFQ is issued saves multiples of that time in variation management, safety incidents, and schedule recovery during the shutdown.
