AI in Mega-Project Construction: Where It Works, Where It Fails, and What Controls Lies with the Board

AI is becoming part of everyday work across major projects, from document review and programme analysis to estimating, design checks and commercial support. Used well, it can save time and help teams see patterns that would otherwise be missed. The risk begins when AI starts influencing important decisions without clear ownership, reliable data or a proper record of how the output was checked. For boards and sponsors, the issue is therefore not whether AI should be used, but where its use needs stronger control.
Infographic showing where AI helps in mega-project construction, where it becomes risky, and the board controls needed for safe AI-assisted decisions.

The main risk is not AI itself. It is allowing AI to influence decisions on cost, programme, design, procurement, contracts or safety without knowing who owns the decision, what information was used and how the output was tested. Boards do not need to govern every AI tool, but they do need clear control where AI can materially affect project outcomes.

1. Key Judgements

1
AI performs best when the project information, baseline and question being asked are already sound. Weak inputs can still produce highly convincing answers.
2
The greatest exposure arises when AI-supported work moves into a real decision without clear accountability for checking and approving the result.
3
Effective governance should focus on the decisions that matter most, rather than trying to control every tool employees may use.

2. What Has Changed

AI use on major projects is moving beyond formal pilots and specialist technology teams. Project staff can now use readily available tools to review documents, test options, summarise information and support technical or commercial work within minutes. Much of this can be useful. However, the speed of adoption means that AI can become part of the decision-making process before the organisation has agreed where it may be used, what information can be entered or how important outputs should be checked.

3. The Real Risk

The underlying problem is a gap between how quickly AI is being adopted and how slowly project controls are adapting. An AI-generated output may pass through several teams and eventually influence a forecast, recommendation or contractual position without anyone recording where it came from, what assumptions it made or whether the source information was reliable.

Treat AI as part of the decision process whenever its output can materially influence cost, programme, safety, design or contractual position.

4. Why This Matters

The use of AI is already becoming normal across professional and project teams, while formal controls are still developing. Waiting for a complete corporate AI framework may therefore leave an immediate gap between policy and what is happening on projects today. The earlier organisations identify where AI is already influencing important work, the easier it is to introduce sensible controls without slowing useful innovation.

Board Implication

Boards and sponsors remain accountable for major decisions even when those decisions have been informed by tools they did not personally select or approve. They therefore need enough visibility to know where AI is materially influencing project decisions, who remains accountable and what evidence exists to challenge the result if necessary.

5. What Needs to Change

Start with the decisions, not the technology. Identify where AI is already being used in areas such as programme, cost, design, procurement, commercial management and safety. For the higher-impact uses: name the accountable owner; define what information may be used; require important outputs to be checked; retain a clear record of material decisions; keep human approval where consequences are significant. The aim is not to slow AI adoption. It is to make sure useful technology does not quietly weaken established project controls.
