Which supporting documents belong behind a tender capability claim?

Start with the evidence requested by the bid

Read the specification, evaluation criteria and returnable schedules together. Identify each capability requirement and the evidence the buyer says it will assess. A project list, signed reference and completion record may serve different purposes even when they relate to the same work.

Create a row for each requirement, including its document or page reference. Record whether it is a mandatory eligibility condition, a scored criterion or supporting information. Do not assume that a document carrying many impressive details will answer every criterion.

National Treasury's evaluation and award guidance provides official context for the role of criteria. For the actual submission, use the issued bid documents and formal clarifications. This article's evidence map is a working method, not an alternative tender form.

Build a claim-to-evidence map

Use this table to organise the review, then replace general suggestions with the actual bid's requirements. If the buyer asks for a specific form or signed statement, a different document may not be an acceptable substitute.

Keep the claim and evidence close enough that the evaluator can follow the connection. Label appendices clearly and refer to the exact attachment instead of saying evidence available on request where the bid requires it at submission.

Support project experience with the relevant facts

For each project, identify the customer, period, work performed and company's role. Distinguish main contractor, subcontractor and joint-venture participation. Explain the portion actually delivered rather than claiming the full value or scope of a project in which the bidder performed only one part.

Use completion or acceptance evidence where the criterion requires completed work. An appointment letter may show that work was awarded, but not that it was completed successfully. If the project is ongoing, label it accurately and check whether the bid permits ongoing experience to count.

Review dates, values and descriptions across the project schedule and attachments. Differences need explanation. Do not modify a third-party record to make it match the tender wording. Request an accurate correction from the issuer where a genuine error exists and keep the original context available.

Check customer references before submission

Read the reference requirements carefully. The bid may specify the content, signatory, contact details, format or period. A general testimonial on a website may not meet a requirement for a signed reference describing comparable work.

Confirm that the reference contact is appropriate and that the information is accurate. Give the customer enough context to identify the project without coaching them to make an unsupported statement. Obtain permission where required before sharing personal contact details or confidential project information.

If a customer cannot provide the prescribed reference in time, raise the issue through the bid's permitted clarification channel. Do not invent a contact, copy a signature or assume that another attachment will be accepted. Record the response and assess whether the business can meet the requirement.

Attribute qualifications and experience to the right people

Match team evidence to the roles proposed for the contract. A qualification held by someone no longer available to the business should not be presented as a resource committed to the work. Confirm availability and the employment or contracting arrangement where it matters.

Separate an individual's previous experience from the bidder's corporate history. Both may be relevant, but they answer different questions. Describe the person's role on past projects and avoid turning a former employer's contract into a claim that the bidding company completed it.

Include the documents actually requested and limit unnecessary personal information. Check whether copies need certification or whether a prescribed declaration applies. Follow the bid's requirement without assuming that every tender uses the same age limit or authentication process for every document.

Demonstrate access to suitable resources

Identify the equipment, facilities or systems needed for the proposed work. State whether they are owned, leased or to be obtained under another arrangement. Use evidence that supports the actual claim and the period in which the resource must be available.

A supplier quotation shows an offer to supply under stated conditions. It does not establish that the bidder already owns the item. If the tender permits planned acquisition, explain the arrangement as required. If it requires existing access, assess whether the evidence meets that condition.

Check specifications as well as availability. An item may be real and available but unsuitable for the required capacity or class of work. Link the relevant technical details to the criterion and avoid sending a large catalogue without identifying which item is proposed.

Check whose capability the documents establish

Compare the legal name and registration number across the bid, profile, certificates and project records. A trading name can be explained, but another company's credentials do not automatically transfer because the businesses share a director or belong to the same group.

For a joint venture or subcontracting arrangement, follow the tender's rules on which party must hold each credential and how combined experience will be assessed. Keep the roles and supporting agreements clear. Do not assume that evidence accepted from a consortium in one bid will be accepted in another.

If a historical name change explains a difference, include appropriate identity evidence where permitted or requested. Preserve the original third-party document rather than altering its name. The evaluator should be able to follow the continuity without relying on an unsupported statement in the profile.

Verify current registrations and document versions

Where current registration is required, check the issuing authority's available verification method and record the result. A saved PDF may be outdated, outside the required scope or issued to the wrong entity. A pending application is not the same as an approved registration.

Use the version of the declaration or form applicable to the bid. The OCPO instruction index, checked in September 2026, includes changes to SBD4. This illustrates why reusing a previous tender folder without reviewing its forms is unreliable.

If the bid pack and a later official instruction appear inconsistent, ask the procuring entity for formal clarification through the stated channel. Keep the answer with the bid record. Do not silently replace a required form based only on a generic online checklist.

Submit a focused and traceable evidence pack

Complete the evidence map with file names, page references and review status. Check that every attachment opens, is legible and corresponds to the final response. Remove unrelated or superseded material that could create contradictions, while retaining all documents the bid requires.

Ask someone other than the writer to test a few claims by following the references. They should be able to identify the claim, locate its evidence and understand its limits. Resolve gaps before submission or make a properly informed decision about whether the bid can proceed.

Profile and proposal support can help organise the response. The business remains responsible for accurate evidence and achievable commitments. A complete capability pack supports evaluation; it does not guarantee qualification, a particular score or an award.

Keep a copy of the exact submitted files and receipt, including the attachment index and any formal clarification incorporated into the response. If clarification is requested later, answer from that record and the underlying evidence. This avoids accidentally relying on a revised attachment that was never included in the original submission.
