Complex Phasing Projects. Phase One. Full Picture.

Phased construction creates compounding commercial risk. Without independent oversight holding the cost thread across the full scheme, exposure accumulates - and rarely surfaces until it is too late to manage.

WHY INDEPENDENT MATTERS

Phase One Decisions.
Full Scheme Clarity.

Phased construction creates compounding commercial risk. Without independent oversight holding the cost thread across the full scheme, exposure accumulates and rarely surfaces until it is too late to manage.

Whole-scheme cost position updated as design evolves
Quantities validated phase by phase against current model
Procurement structure that holds from Phase 1 to completion
Cross-phase variation impact tracked and controlled
Each phase formally closed out before the next begins

INDEPENDENT WHOLE-SCHEME OVERSIGHT
Phase 1 decisions create Phase 3 exposure.
THE PROBLEM

Phase 1 decisions create Phase 3 exposure.

Phasing introduces commercial risk at every interface. Enabling works that are under-scoped in Phase 1 create claims in Phase 2. Programme delays trigger acceleration pressure in the next phase. Without a connected commercial view, exposure accumulates invisibly.

Enabling works under-scoped in early phases creating later claims
Programme slippage in one phase generating acceleration costs in the next
Procurement structures that don't hold across the full scheme
Cost plans produced phase by phase without a whole-scheme view
Phase interfaces where commercial responsibility is never clearly defined

WHEN TO ENGAGE

Before Phase 1 Procurement,
If At All Possible.

The terms you agree in Phase 1 shape every phase after.

Discuss Your Project

The procurement structure and contract terms agreed for Phase 1 shape what’s available to you commercially for every subsequent phase. We’re most effective when engaged before Phase 1 procurement. We can also step in between phases – to close out the previous phase cleanly and establish the commercial position for the next.

Pre-Phase 1 Engagement

Procurement structure and whole-scheme cost position established before Phase 1 commitment – protecting every phase that follows.

Between Phases Support

Phase complete but not formally closed out? We establish the actual cost position before the next phase commences.

HOW WE WORK

One Commercial Thread From Phase 1 to Final Account.

Phased schemes need a cost position that holds across every interface. This is how we maintain it from the first procurement decision to the last final account.

1

Set Brief

Share phasing logic, programme and BIM model and confirm the funding structure and priorities per phase.
2

Validate Phase by Phase

We validate quantities for each phase against the current design model never carrying forward earlier assumptions.
3

Hold the Scheme View

We maintain one connected cost position across every phase updated as design and procurement evolve.
4

Close Out Each Phase

We formally close out each phase before the next begins so commercial issues never carry into the next phase.

FREQUENTLY ASKED QUESTIONS

Complex Phasing Projects – Frequently Asked Questions

Quick answers to the most common questions about independent commercial oversight across phased construction schemes.

Whole-scheme cost when only Phase 1 is designed - can you do that?
Yes. We model whole-scheme cost with appropriate allowances for later phases, based on current design intent, procurement assumptions and benchmarked data. We're explicit about what's fixed and what's still an assumption - so the cost position is defensible, not optimistic.
How do you close out a phase formally before the next begins?
Through a structured final account process - all variations agreed, quantities reconciled, final account certified. That prevents Phase 1 commercial issues from carrying into Phase 2.
What happens when programme slippage in one phase creates pressure on the next?
We identify the commercial implications of programme slippage early - acceleration costs, prolongation, potential claims - and advise on how to manage the contract position before it becomes a dispute.
Can you manage separate contractor appointments across phases?
Yes. We maintain a connected commercial view across separate contractor appointments - ensuring the cost position, variation records and contract history are consistent across every phase.
We're between phases and the cost position is unclear. Can you step in?
Yes. We carry out phase-level cost rebaselines - establishing the actual position at phase completion, what's in variation, and what the exposure looks like going into the next phase.
