Quantity surveying that protects your project from day one.
A proactive approach to cost and contract management — minimising overruns, contractual claims and disputes before they arise. Your objectives, our priority.
1987
We opened our doors in the late 1980s and we've been protecting projects for clients across the globe ever since.
About Us
We make our clients' objectives our priority.
At Ian Allan Associates (UK) Ltd, we take a proactive approach to cost and contract management, helping to minimise the risk of cost overruns, contractual claims, and disputes before they arise.
Our team has extensive experience across a wide range of contract forms — including NEC3, JCT, ICE, GC/Works/1, Management Contracts, DOM/1, FCEC, FIDIC and bespoke national and international agreements.
In today's challenging economic environment, where margins are often tight, we provide the expertise and oversight needed to monitor costs, manage risk, and maintain financial control throughout the project lifecycle.
