Why a consultant’s performance incentive should be earned only after a saving has been delivered, measured and verified.

By Mirza K. Baig, Managing Director, Proconstruct Design and Engineering

Almost every construction project reaches a moment when someone says, “We could do this more efficiently.” Sometimes they are right. Often, though, an idea that looks promising in a meeting falls apart in execution. The alternative cannot be built as drawn, it needs extra work that cancels the saving, or it trades a lower upfront cost for problems that surface later.

For a project owner, this is a genuine dilemma. How do you encourage engineers to look for smarter solutions without paying for suggestions that never become real savings?

Proconstruct Design and Engineering answers with a mutual-benefit model built on one rule: value comes first, and reward follows. Additional compensation is linked to the net benefit the project actually receives, and only once that benefit has been shown to be practical, measurable and verified. This article explains how the model works, why it is designed this way, and what both sides should agree before using it.

Why ideas alone are not enough

An idea has potential. A verified result has value. The gap between the two is where many optimisation exercises lose credibility.

A consultant can propose an alternative structural approach quickly. Whether it works on a real site, with real constraints, is a different question. Potential savings are not the same as actual savings, and a proposal that has never been applied or measured has not yet given the project anything.

If compensation were triggered by the proposal itself, the owner would carry all the risk, paying for opportunities that may never materialise. A value-based model moves the reward to the point where the benefit is real. It keeps attention on implementable results rather than theoretical recommendations.

The core principle: value first, reward follows

The model rests on two linked rules.

No advance

Additional compensation should not be claimed merely for identifying an opportunity or proposing an alternative approach. The optimisation must first demonstrate that it can be applied in practice and that it delivers a measurable benefit to the project. Until then, there is no basis for performance-based compensation. In other words, no incentive is claimed ahead of proof.

No value addition, no claim

Not every optimisation review ends in a saving. Sometimes the existing solution turns out to be the most appropriate one. Sometimes an alternative looks attractive but cannot be implemented in practice. In those cases, the time and effort spent evaluating options do not, by themselves, create an entitlement to an incentive.

This is what makes the arrangement transparent. The owner pays extra only when a genuine benefit has been delivered, and both parties know in advance what triggers a reward.

From proposal to proof

It helps to picture the model as a chain of five steps: idea, application, measurement, verification, reward. An opportunity is identified, then applied on the project, then its impact is quantified, and then the benefit is confirmed against an agreed basis. Only after that does the incentive come into play. Verification is the gate. Nothing before it earns a reward.

Measuring value: the net benefit

Under this model, the incentive is linked to the net value created, not the headline saving:

Net value created = Gross benefit − Additional costs

The benefit must be measurable, practical and verifiable, and it must be assessed as a whole. If achieving a saving requires extra expenditure, that cost is deducted from the gross benefit. Only the resulting net figure forms the basis for performance-based compensation.

Where structural value comes from

In structural design, the sources of value are practical and often unglamorous: using materials more efficiently, improving construction methodology, simplifying execution, reducing wastage, coordinating better, standardising effectively, and avoiding modifications that could have been prevented. Together these improve overall project efficiency.

Shared benefit: aligning engineering and project economics

Once value addition has been verified, an agreed portion of the net benefit may be considered as compensation for the party responsible for the optimisation. The project retains the remainder. The greater the verified value, the greater the opportunity for reward.

This aligns engineering expertise with project economics. For the owner, risk moves from paying for proposals to paying for results. For the engineer, the reward depends on the quality of the solution rather than the volume of suggestions. Because only verified, net benefit counts, the incentive favours ideas that actually work.

What to agree before you start

The principles are simple, but a contract has to turn them into specifics. The following points are practical recommendations for anyone adopting the model:

• Baseline: what cost or design the saving is measured against, agreed before work begins.
• The share: the percentage or formula behind “an agreed portion”, and whether there is a cap.

Agreeing these in advance is what turns a good principle into a workable, dispute-resistant arrangement.

Conclusion

Reward should follow results. Ideas are welcome, but they are valued only once tested. Savings count only when they are net and verified. Cost reduction matters only when it preserves the value the project needs.

For owners, the model offers a way to encourage optimisation without paying for speculation. For engineers, it ties reward to the quality of their solutions. When value is genuinely created, both sides share in it.
