Work through a realistic tender — Construction & civil engineering

By the end of this lesson, you will be able to defend a bid decision and prepare a consistent submission.

Common to all countries

Make a decision that survives delivery

A bid review has three separate gates: admissibility, a credible route to a competitive score, and the ability to deliver at an acceptable return. A high score cannot cure an inadmissible offer; a technically possible offer can still be commercially unsound. Give each unresolved issue an owner and a decision deadline before the submission cut-off.

Assemble the final response from the controlled requirements and evidence registers. Check names, totals, document versions, signatures, portal fields and uploaded files. Use an independent read-through to find contradictions between the method, staffing and price. After a permitted test of the submission workflow, allow time for the actual upload and retain the receipt. A finished PDF on your computer is not a submitted offer.

Worked example — Renovate an occupied library

This is a fictional teaching case. Quantities, prices and contractual conditions below are assumptions for the exercise, not legal requirements or market benchmarks.

A town wants to replace lighting and refurbish reading rooms while keeping part of its library open. The result is usable space delivered in phases, not simply a completed bill of quantities.

Review position. The team can deliver the base requirement, but one clarification remains open and the extra cost below is not included in its original price. Submission is five working days away; this is a case assumption.

A drawing shows twelve luminaires while the quantity schedule lists ten. Record both document references and request a written reconciliation; do not quietly choose the cheaper quantity.

Restricted hours reduce output and an undisclosed service behind a wall can interrupt the sequence. Price the known working constraints; assign investigation and change-control actions for uncertain conditions instead of hiding them inside an unexplained contingency.

Item	Cost (currency units)
Labour	42,000
Materials	28,000
Site setup and management	10,000
Total	80,000

Total cost is 80,000. To retain 20% of the selling price as profit, price is 80,000 ÷ 0.80 = 100,000. If “Additional restricted-hours work” adds 8,000 to cost without a price increase, profit becomes 12,000, or 12% of price. Preserving 20% would require 110,000, only where the procurement permits that price. A cost increase does not automatically entitle the supplier to a contract price increase.

Country specific — what to verify

Check local contractor qualifications, building approvals, site-safety responsibilities and mandatory insurance for the actual activities. Retention, statutory defects liability, price revision and subcontractor payment depend on the governing regime and contract; do not import another country’s standard clauses.

Local works contract documents and submission requirements. Use the destination-country module and the actual tender pack. The sources below are references with their own scope; they do not form a single worldwide regime. For the general method, revisit the foundations.

Put it into practice

Prepare a final review with four decisions: admissibility, clarification, return and submission. State the conditions for a yes and the conditions requiring a no. Produce three response headings linked to requirements.

Model answer

Model decision: conditional bid, not immediate approval. Obtain the official clarification, confirm evidence and resources, then decide the price or withdraw before submission. Do not conceal non-compliance in a prohibited qualification. The three response sections are understanding the need, method and resources, then controls and acceptance. Agree how completed areas, test certificates, as-built documents and defects are recorded. Separate practical completion from correction of outstanding defects and from final financial settlement, according to the contract.

Keep this worksheet in your working file. The quiz below checks the lesson’s decisions; passing it is neither a professional qualification nor a guarantee of an award.
