Valuation is the process of determining the monetary value of construction work, assets, or projects for payment, financing, or reporting purposes.

In construction, valuation refers to the formal assessment of the monetary value of work completed, materials installed, or assets associated with a project. Valuations are commonly used to determine progress payments, project financing amounts, insurance coverage, or overall project worth at a specific point in time. They provide a financial snapshot that supports transparent cost management.

Valuations are typically prepared by contractors, quantity surveyors, or project managers and are based on contract terms, schedules of values, unit costs, and verified site progress. Interim valuations are issued periodically throughout construction, while final valuations are completed at project closeout. Accuracy is essential, as valuations directly affect cash flow, budgeting, and financial reporting.

From a contractual and risk perspective, valuation plays a key role in dispute avoidance and compliance. Most construction contracts define how and when valuations are performed, including documentation requirements and approval processes. Clear, well-supported valuations help ensure fair compensation, maintain lender confidence, and support effective project controls on both public and private construction projects.

On large commercial projects, interim valuations can involve thousands of line items and are often audited before payment is released.
