Why Contract Reviews Matter Before You Sign
Payment terms, notice periods, change mechanisms, design responsibility and risk transfer — the clauses that decide whether a project is commercially safe are agreed before work starts.
By the time a payment dispute or a delay claim lands, your commercial position was usually decided months earlier — in the contract you signed. A pre-signature review is one of the cheapest pieces of protection available to a construction business.
Payment terms
Check the payment cycle from application to final payment date, and mark the dates in your programme. Long payment periods, pay-when-certified mechanics and aggressive payless notice provisions all push financing cost onto you. Retention percentages and release triggers should be understood before the price is agreed, not discovered at the first application.
Notice periods
Modern contracts are full of time bars. NEC compensation events generally require notice within eight weeks of awareness; many bespoke subcontracts cut that down dramatically and make notice a condition precedent. Miss the notice, lose the money — regardless of merit. A review pulls every notice obligation into one schedule the site team can actually follow.
Change mechanisms
How is a variation instructed, priced and agreed? Who can instruct one? What happens if you proceed on an email from someone without authority? Understanding the change mechanism — Variations under JCT, Compensation Events under NEC, Variations under FIDIC, or whatever a bespoke form invents — determines whether change makes you money or costs you money.
Compensation events and claims
Under NEC, compensation events cover both time and money through quotations built on defined cost. The process is workable if you know it and brutal if you do not. Under JCT, loss and expense runs on a different track from extension of time. A review tells your team which regime applies and what records it demands.
Liability, indemnities and caps
Bespoke amendments often widen indemnities, delete liability caps, or insert fitness-for-purpose obligations that your insurance may not cover. Consequential loss exclusions can be stripped out quietly. These clauses rarely bite — but when they bite, they are existential.
Design responsibility
Contractor-designed portions, "development of design" wording and co-ordination obligations can transfer design risk without anyone noticing. If you carry design responsibility, your PI insurance, your programme and your price all need to reflect it.
Programme obligations and risk transfer
Check what the programme is contractually: a document you provide for information, or a binding obligation with damages attached. Look at liquidated damages levels, float ownership, concurrent delay wording, and ground condition risk. Bespoke subcontracts frequently pass down risk the main contractor holds — sometimes more than they hold.
NEC, JCT, FIDIC and bespoke forms
Standard forms are at least predictable. The real danger is the schedule of amendments and the bespoke subcontract. Every unfamiliar form deserves a structured review covering payment, notices, change, liability, design, programme and termination before signature.
