Understanding the Valuation of Works in Quantity Surveying: A Complete Guide

Managing cash flow effectively during construction is critical to project success – and one of the most important tools for this is the valuation of works.
Yet many clients and contractors don’t fully understand how the valuation process works or why it’s so essential.

In today’s article, we’ll provide a complete guide to the valuation of works in quantity surveying, and explain how expert support from Reltic Construction Consultants ensures financial clarity and control throughout your project.

1. What Is Valuation of Works?

The valuation of works is the process of:

  • Assessing the value of work completed on-site at a given time

  • Certifying how much should be paid to the contractor for that work

  • Ensuring payments match actual project progress

Valuations are typically done monthly and form the basis for interim payments to the contractor.

It’s all about linking payments to real, measurable construction progress.

2. Why Is Valuation of Works Important?

Accurate valuations are essential because they:

  • Maintain fair cash flow for contractors and suppliers

  • Protect clients from overpaying before work is completed

  • Provide financial transparency and accountability

Poor valuations can lead to cash flow issues, disputes, and even project failure — so professional handling is critical.

3. The Role of the Quantity Surveyor

During valuations, the quantity surveying consultant will:

  • Visit the site to inspect completed work

  • Measure quantities against the Bill of Quantities

  • Assess the value of materials stored on-site

  • Recommend the certified amount for interim payments

Quantity surveyors ensure that valuations are objective, accurate, and based on contractual agreements.

4. How Valuation of Works Supports Cash Flow Management

Regular, accurate valuations allow clients to:

  • Forecast cash flow needs with greater precision

  • Plan funding drawdowns from lenders

  • Manage project finances in a structured, predictable way

This helps prevent both underpayment (leading to contractor delays) and overpayment (leading to cash exposure).

5. Managing Variations Through Valuations

Variations (changes to the original scope) are common in construction.
Quantity surveyors ensure that:

  • Variations are assessed fairly

  • Additional works are valued correctly

  • Payment adjustments are made accurately

This protects both client and contractor interests and keeps the project moving forward smoothly.

6. Final Valuation and Project Close-Out

At the end of the project, the quantity surveyor:

  • Prepares the final valuation

  • Settles outstanding claims and retention releases

  • Agrees the final account between client and contractor

A clear, well-managed final valuation ensures a clean financial close-out with minimal disputes.
