A complete MEP tender submission comes from a fixed sequence: register the tender and its dates, check the documents are complete, measure quantities, compile the BOQ in the client's format, build up rates from your own prices and supplier quotes, close out queries and addenda, then compile and check the submission against a compliance checklist before sign-off. Most lost margin and late submissions trace back to a skipped step, not a wrong rate. The checklist below is the one our estimators work through on M&E tenders. It also shows which steps you can hand to outside tender support and which your team should keep.
The tender sequence, step by step
- Register the tender. Record the closing date, the query deadline, the site visit date and the submission method. Work backwards to set internal deadlines for take-off, pricing and review.
- Check the documents are complete. List every drawing, specification section, schedule and form in the tender. Compare against the drawing register in the tender documents and query anything missing straight away.
- Build a scope matrix by trade. Split the work into fire protection, ACMV, electrical, ELV, and plumbing and sanitary. Note who supplies and who installs each item, and anything marked as by others.
- Measure quantities. Take off materials and labour from the drawings and specifications. Organise quantities by building, floor and area so they can be checked and reused for claims later.
- Compile the BOQ. Put the quantities into the client's BOQ format if one is given. If not, use your own. Keep item descriptions aligned with the specification wording.
- Build up the rates. Price materials and installation from your price lists and supplier quotes. Show the build-up so a reviewer can see where each rate came from.
- Get and compare subcontractor and supplier quotes. Put them side by side on the same scope. Note exclusions and differences before choosing which to carry.
- Raise tender queries. Draft RFIs for conflicts between drawings, specifications and BOQ, and for anything unclear. Track each query and its answer.
- Review every addendum. Check what each addendum changes in quantities, specifications or conditions. Update the BOQ and record that the addendum has been priced.
- Write qualifications and exclusions. State your assumptions clearly. Do not use them to cover scope you simply did not have time to measure.
- Compile the submission. Assemble the priced BOQ, forms, schedules and any technical submittals in the order the tender asks for.
- Check and sign off. Run the compliance checklist. Your estimator or commercial manager reviews the pricing and signs off before submission.
- File everything. Keep the submitted set, the query log and the rate build-ups under document control. You will need them at award, for variations and for progress claims.
Compliance checklist before you submit
Want to tick these off on your next tender? Download the free Excel checklist from the box on this page: the 13-step sequence, this compliance list and a timeline planner, with owner and status columns.
- Every document in the tender drawing register was received and reviewed
- All addenda are listed, priced and acknowledged in the form required
- The BOQ follows the client's format, item numbering and units
- No BOQ item is left blank unless the tender allows it, and blanks are explained
- Rate build-ups are saved and traceable to price lists or quotes
- Subcontractor and supplier quotes are compared on the same scope
- Every tender query has an answer, or the assumption made is stated
- Qualifications and exclusions match the pricing
- Totals and carried-forward figures have been checked
- Forms are completed and signed by the authorised person
- Technical submittals requested in the tender are included
- The submission method and closing date are confirmed
Planning the internal timeline
Set the internal dates before anyone starts measuring. Work back from the closing date and leave time for:
- Final review and sign-off by the person who will sign the forms
- Compilation and printing or uploading, which always takes longer than expected
- Late addenda, which can arrive close to closing and change quantities
- Subcontractor and supplier quotes, which often arrive after you asked for them
- The query deadline, which is usually well before the closing date
If the dates do not fit, decide early whether to ask for an extension, bring in support, or decline the tender. Declining early costs less than a rushed bid priced on guesswork.
Who does what
| Tender stage | Deliverable | Can be outsourced | Kept in-house |
|---|---|---|---|
| Document review | Drawing register check, missing-document list | Yes | Approving the query list |
| Take-off | Measured quantities by area | Yes | Spot checks |
| BOQ compilation | BOQ in the client's format | Yes | Final review |
| Rate build-up | Built-up rates and cost summary | Yes, using your rates | Margin and final prices |
| Queries and addenda | RFI log, addendum review, scope gaps | Yes | Sending queries to the client |
| Tender compilation | Compiled submission, quote comparison | Yes | Sign-off and submission |
Using tender support services well
Outside tender support saves the most time when your estimators spend their hours on judgement, not measuring. Hand over the whole tender in one transmittal: drawings, specifications, the BOQ format, addenda received so far and the closing date. Say whether you need measured quantities only, or a priced BOQ built up from your rates. Name one person to answer queries.
Keep the commercial decisions yourself. Your rates, suppliers and margins should stay yours. The support team prepares the BOQ and rate build-ups; your team reviews and signs off.
If you tender often, compare project-based BOQ support with a dedicated estimator on a monthly basis. The trade-offs are covered in outsourcing MEP estimation.
Fire protection packages
Fire protection tenders often include design-and-build elements. You may need a sprinkler layout and hydraulic calculation to price pipe sizes and the fire pump with any confidence. See sprinkler hydraulic calculations for how that works, and fire protection design for the design scope.
After award
The same quantities and build-ups support the project once it is won. Keep the take-off organised by area so it can be used for variation pricing, budget against actual tracking and monthly progress claims. If shop drawings are needed after award, see shop drawing services.
Common mistakes
- Starting take-off before checking the documents. Missing drawings found late leave no time for queries.
- Copying quantities from an old job. Similar buildings still differ. Measure from the current drawings.
- Pricing addenda without recording them. If you cannot show an addendum was priced, you cannot rely on it later.
- Comparing quotes that cover different scope. One supplier's lower price often reflects an exclusion, not a better rate.
- Using qualifications to hide gaps. Clients read them, and too many weaken the bid.
- Rate build-ups that cannot be traced. If nobody can explain a rate after award, variations become harder to price.
- No final arithmetic check. Carried-forward totals and summary pages are where errors hide.
- Losing the tender set. Without the submitted documents and query log, disputes after award are hard to settle.
How Newham can help
Newham's estimators prepare quantity take-offs, BOQs in your or the client's format, and rate build-ups from your price lists and supplier quotes across fire protection, ACMV, electrical, ELV, and plumbing and sanitary. We also draft tender queries, review addenda, compare subcontractor quotes and compile the tender submission, while your team keeps the final say on pricing. Work is priced per deliverable or on a monthly retainer, billed in SGD, with the scope confirmed in writing.
