Before signature

The cheapest commercial problem is the one removed before order.

Main-contractor amendments can shift design, programme, payment, insurance and loss exposure well beyond the standard form. A review should do more than repeat clauses; it should show what to negotiate and what the project team must manage if the wording remains.

We produce a concise risk schedule, recommended amendments and a practical project brief after terms are agreed.

Review scope

Commercial terms viewed as one connected risk.

The contract-review capacity within the retainer is matched to contract value, complexity and deadlines. Common focus areas include:

Scope and design

Document hierarchy, fitness obligations, design development, discrepancies and responsibility gaps.

Programme and delay

Start conditions, completion, notices, extensions of time, acceleration and liquidated damages.

Payment

Applications, notices, set-off, retention, vesting, payment periods and final-date mechanisms.

Change

Instruction authority, notification, valuation, quotation procedures and time-bar exposure.

Liability

Indemnities, caps, consequential loss, warranties, insurance and third-party obligations.

Termination and suspension

Trigger events, notice steps, payment consequences and rights on insolvency or default.

Questions

Contract support in context.

How quickly can a contract be reviewed?

Timescale depends on length, amendments, project value and urgency. We will confirm the included retainer capacity and return date before work starts and flag any immediate signature or mobilisation risk.

Do you review purchase orders and framework call-offs?

Yes. The operative terms may sit across a framework, order, task order, scope, amendments and referenced main-contract provisions. The review identifies which documents actually apply and any conflicts between them.

Can you negotiate terms directly?

We can prepare and discuss commercial amendments within the agreed authority. Matters requiring legal advice are referred to your solicitor, with the commercial issue clearly framed.

Can you draft a notice after an event has happened?

Yes, but timing and prior correspondence matter. We first review the clause, chronology and what has already been communicated, then advise on the strongest accurate response still available.
