The Art of Tendering & Bidding: From Invitation to Award

A practical, case-led course on how construction tenders are formed, evaluated, negotiated, challenged, and ultimately converted into a contract.

Tendering is often treated as a procurement process: issue the documents, receive the bids, evaluate them, and announce the winner. In practice, the difficult questions arise in the spaces between those steps.

When does a tender become binding? What happens when a bidder discovers a major pricing error? Can an employer negotiate after bids are submitted? When does a low tender become abnormally low? What is the consequence when a compliant tender is ignored? And when does a letter of intent or early works instruction create a contract before anyone intended to award one?

This course develops the commercial and contractual judgment needed to navigate those situations.

The case follows Cavanagh Construction through a $12.8M campus tender for the Lakeshore Public Schools Authority. A $480K extension error, 90-day tender validity period, and $100K tender security create pressure from the moment the bid is submitted. As the tender progresses, learners encounter mistakes, evaluation decisions, negotiation traps, low bids, alternative bids, subcontractor arrangements, early works, and competing award strategies.

The case provides a continuous thread across twelve lessons, with each stage presenting a new decision about how the tender should be handled.

Module 1 establishes the foundations: who is bound, when obligations arise, how mistakes should be handled, and how conduct during evaluation can affect the path to award.

Module 2 moves into the difficult middle ground. You will examine post-tender negotiation and the counter-offer trap, assess abnormally low tenders before rejecting them, and consider what a bidder may be able to claim when its tender is ignored or the process becomes abortive.

Module 3 turns to tender structures and the supply chain. Explore two-stage tendering, prequalification, design-build procurement, alternative and qualified bids, and the different roles of nominated, named, and domestic subcontractors in the bidding process.

Module 4 addresses the instruments and behaviours that can complicate the transition from tender to contract. You will examine letters of intent, early works, premature starts, cover pricing, collusion risks, bid shopping ethics, competitive proposals, BAFO processes, and framework pricing.

By the end of the course, you will be able to:

• Understand when tender obligations arise and how tender documents create different forms of commitment.

• Identify and respond to pricing and bid mistakes.

• Evaluate tenders while maintaining procedural and contractual integrity.

• Recognize the risks of post-tender negotiation and counter-offers.

• Assess abnormally low tenders using a structured investigation approach.

• Understand the consequences of ignored, alternative, qualified, and tagged bids.

• Compare different tender structures and supply-chain arrangements.

• Manage letters of intent and early works without creating unintended contractual exposure.

• Recognize ethical and commercial risks surrounding cover pricing, collusion, and bid shopping.

• Understand competitive proposals, BAFO, and framework pricing models.

The course is not a guide to one country's procurement regulations or an e-tendering systems course. It focuses instead on the contractual, commercial, and decision-making principles that sit underneath a construction tender.

The practical discipline is simple:

understand the invitation → protect the bid → evaluate fairly → negotiate carefully → control the award → create the contract.
