Post-Contract Cost Support

Commercial cost management and technical support to protect cash flow, manage variations, and maintain control once work is underway.

Who we are

Why Post-Contract Cost Control Matters

Once a project is live, commercial risk increases. Valuation delays, poorly managed variations, and inconsistent cost tracking can quickly impact cash flow and profitability.

Without structured cost management, contractors often absorb additional administration, miss recoverable costs, or under-price changes during construction.

CNJ provides independent, contractor-side support to manage valuations, assess variations accurately, and maintain financial control throughout the build.

Accurate valuations aligned to contract terms
Clear assessment of variations before agreement
Reduced administrative burden on site teams
Improved cash flow and commercial visibility

Our Construction Support Services

Clear cost oversight and protection from start to finish.

Cost Management

We manage valuations, monitor expenditure, and reconcile project costs throughout the build, ensuring payment terms are followed and cash flow remains stable. This service removes the administrative burden of interim valuations and final accounts, allowing contractors to focus on delivery while maintaining commercial control.

Technical Advice & Variations

We provide technical advice and support with pricing and managing variations, ensuring additional works and scope changes are correctly assessed and agreed. This protects contractors from carrying out unpaid work and reduces the risk of pricing variations inaccurately.
