The decision
Test the consequences of a material change before the project commits to it.
Project decision assurance for major projects
Make the project decision before the consequences make it for you.
When a live change pulls design, cost and programme apart, Clockwork helps Project Directors and senior project sponsors reconcile the evidence, test the credible options and see the consequences before committing.
The result is a decision your team can act on — and you can explain and defend.

The project problem
Change breaks construction coordination.
A change rarely affects one drawing. It moves through design, quantities, cost, sequence, programme and approvals. Clockwork keeps those consequences connected—and carries the approved decision into verified project artefacts.
Flagship case study · Mitre Wharf
One extra floor. Everything else moves.
A major design change does not stay in the model. It changes quantities, construction logic, package prices, programme dependencies, risk and the decision the Project Director must own.
The evidence
Reconcile contractor and specialist subcontractor prices and programmes with BCIS benchmarks and the overall build cost normalised by GIFA.
The output
Show how the option moves design, cost, programme and risk, with the basis and uncertainty visible for the accountable decision-maker.

Governed cost output
A public-safe extract showing how project geometry becomes classified NRM2 quantities and cost information.
Case-study extract from the governed Mitre Wharf cost model. It combines contractor tender inputs with governed benchmark rates; quantities and commercial values are materially rounded and client details withheld. View full size ↗
All 916 governed cost items, summarized as 36 representative line items across 6 groups.
From project option to coordinated deliverables.
1Agree the metrics
Define what matters for the decision: design performance, buildability, cost, programme, carbon, risk or another project-specific measure.
2Test the options
Develop and compare viable options using agreed evidence, assumptions and weighting.
3Make the decision
Present the consequences clearly so the responsible project team can make and approve an informed decision.
4Carry it through
Develop the selected option and update the drawings, specifications, reports, quantities and programme information affected by it.
One decision, carried consistently through the project information.
What Clockwork delivers.
Clockwork appointments are built around useful project outputs, not a software licence. The exact package is agreed around the project stage, decision and responsibilities.

Start with a Project Decision Review.
Bring the live decision and the information you already have. Clockwork reconciles the evidence, tests the credible options and returns a concise basis for action.
- •A reconciled project state and explicit assumptions
- •The important inconsistencies and missing decisions
- •Tested options across design, cost, programme and risk
- •Confidence, unresolved risk and a concise decision pack
If the decision needs deeper development, continue into an Option Test or a Verified Decision Pack.
Evidence from live project work

Foundation response comparison
Settlement response under different modelling assumptions
Three modelling assumptions are compared to expose how predicted foundation response changes, making the sensitivity of the result visible for engineering review.

Professional control
Accelerated by technology. Reviewed by people.
Clockwork uses connected digital workflows, calculation tools and selected AI systems to accelerate analysis and production. Professional judgement, review and approval remain with the responsible construction team.
Traceable assumptionsInputs, assumptions, evidence and decisions remain connected to the resulting work.
Deterministic calculationsWhere a deterministic answer is required, explicit engineering rules and verified calculation methods are used rather than model inference.
Human reviewCritical deliverables are reviewed by the responsible professional before issue.
Controlled project informationAccess, processing, retention and transfer arrangements are agreed for each commission.

Bring us the live decision.
Tell us what must be decided, when it must be decided and who is accountable. We will define a focused first commission around the evidence available.
Initial discussions are confidential. Do not send sensitive project information until the appropriate information-sharing arrangements are in place.
