The short answer
Prequalify a short list on track record, finances, team and quality; have every firm price the same drawings and specification; compare price alongside programme and method; then appoint in writing on total value, not the lowest number.
What the tender decides
Three questions drive the process: who is genuinely capable of the work, who has priced exactly the same scope, and whose price, programme and method together fit the property best. The owner is the client and makes the appointment; the consultant's job is to make that decision clear.
Before anyone is invited, the project needs a complete set of drawings and a written specification package. That is the only basis on which bids can be compared fairly.
Step 1: prequalify before anyone prices
Prequalification tests suitability before price is discussed:
- Track record: completed villa or comparable residential fit-outs, and the scope each firm actually delivered.
- Financial standing: evidence requested as part of the submission, not after the appointment is imminent.
- Team: the project manager, site team and key trades who will actually run your job.
- Quality: completed work of similar scale and specification, judged on what has been handed over.
The result is a short list of firms whose capability is already established, so the tender becomes a comparison of price, programme and method.
Step 2: everyone prices the same package
Send the same drawings and specification to every firm, at the same time, with the same deadline and format. If one firm prices a lower grade of finish or leaves out the joinery, its number is not a lower price; it is a different project.
- Ask for a priced schedule keyed to the drawings, with allowances, provisional sums and exclusions shown on the page.
- Run one written clarification channel and share every answer with every bidder.
- Keep bids sealed until the deadline.
Step 3: compare price, programme and method
Price is one of three dimensions. The programme is the realistic sequence and duration of the works; the method is how the firm will deliver them, including trade sequencing, protection of installed finishes and, where relevant, working around an occupied villa.
The cheapest bid that cannot hold the programme, or carries the most exclusions, often costs more later as delay, rework and variations. Present the outcome as a comparison matrix, not a single number, so the owner can see where each firm is strong and where the price difference comes from.
Step 4: the owner appoints, in writing
- Decide on total value, not headline price.
- Attach the agreed scope, programme, method, payment terms and change-control procedure to the contract.
- Record why the chosen firm was selected.
- Supervise the works against the same documents that were tendered, so what was priced is what gets built.
Pitfalls to avoid
- Inviting too many firms, which invites speculative pricing.
- Issuing partial drawings or leaving finishes to be decided later.
- Choosing on the lowest number alone.
- Agreeing change control after the contract is signed.
- Treating the tender as the end of the process rather than the baseline for supervision.
How Ganggaan runs it
Ganggaan prepares the drawings and specification, prequalifies and tenders the contractor, presents the comparison, and then supervises the works against the same documents. The appointment stays with the owner. Ganggaan is not the building contractor. See project management and site supervision and our guide to why a villa build needs a project manager.
