Services for Main Contractors

CNQS have experience working with a variety of main contractors, covering a range of project values from £1 million to £250 million. Our commercial staff have experience within sectors including residential, commercial, nuclear, sport, leisure, education and healthcare. Please see below an example of the services we offer to the main contractor market.


The key to success in a project begins with the accurate tendering and procurement of the supply chain. We can assist in the measurement of work, distribution of tender documentation, and analysis of received quotations. This will provide you with all of the necessary information to decide the best sub-contractor for your requirements.

Contract Negotiation

Once a sub-contractor has been selected, entering a contract with them can be a lengthy process involving clause negotiation, contract sum agreement and general collation of documentation. We can assist with every step in this process, allowing you to focus your attention with other project requirements.

Quantity Surveying

With many years of site based Quantity Surveying experience, we can provide all forms of commercial service. This includes the option to have a full-time Quantity Surveyor provided for your scheme, or alternatively a part-time provision that is flexible to your project requirements.

Variation Recovery

Throughout the life cycle of a project, variations can become overwhelming as other needs are attended. We provide a service that focuses purely on variation administration with both your Client and supply chain to ensure works are valued accurately and administered correctly.
