Why the lowest construction bid may not deliver the best value for money

In a tight construction market, it is tempting to treat the lowest tender as the safest financial choice. Yet the cheapest bid is not always the most economical once a project moves from paper to site.

A lower price can conceal incomplete scope, optimistic assumptions, thin margins or deliberate cutbacks. As the construction sector has long recognised, those issues may not appear until work is under way, when they can surface as delays, defects, disputes, safety pressures and h...

igher maintenance costs. What initially looked like savings can end up making a project more expensive over its lifetime.

That is why procurement is increasingly framed as a question of value rather than price alone. Best value procurement seeks the strongest overall outcome, weighing cost alongside quality, technical ability, past performance, delivery reliability, risk and long-term performance. The aim is not to select the most expensive bidder, but the one most capable of delivering the required result at the right cost.

This distinction matters most on complex, high-risk or strategically important schemes. A contractor offering a very low figure may simply have allowed for less than the full scope, or may be relying on assumptions that prove unrealistic once construction begins. Problems can follow quickly: weaker workmanship, programme slippage, cash-flow strain, increased claims, and rework that erodes any apparent saving. In the worst cases, the result is premature asset failure and avoidable remedial spending.

For public-sector work, the stakes are even higher. Infrastructure is meant to serve communities for years, sometimes decades, and a poor procurement decision can leave residents waiting longer for essential services while governments face the cost of corrections, termination or completion by others. In that context, the real question is not simply what a project costs at the outset, but what it will cost if the wrong contractor is appointed.

A more balanced approach requires clients to define clear evaluation criteria, test whether tenders are complete and realistic, and consider contractor capability, methodology, programme credibility and risk management as well as price. Industry guidance on best value procurement consistently points to the same conclusion: the lowest number on the page is only one part of the decision.

The lesson is straightforward. Value for money is not about paying the least up front. It is about securing the right outcome, to the required standard, within the required timeframe and with risks properly managed. In construction, that is often worth more than the cheapest bid.
