Market leadership and expertise


ProQS is a chartered firm regulated by the RICS. We have been fortunate to have consulted on some of the most prestigious and largest projects ever to be constructed in the UK. Our work has seen us consult with Costain, Lang O’Rourke as well as numerous other organisations.

The diverse aspect of our work across domestic, commercial and civil engineering means our knowledge base and expertise is vast, and we are able to work on the smallest to the largest of projects acting as part of a larger QS team.

Our services are comprehensive, and ProQS can interject at anytime during planning and construction phases. We may be asked to produce the initial reports for a new construction project, or indeed act as an ‘Expert Witness’ should a conflict occur during and on completion of a project. We can also help in rectifying the situation with a commerciallydistressed project, and look at a methodology and process to rectify the situation and take that project through to completion.

A comprehensive breakdown of ourservices is detailed further on the website!

“I encountered Kieron when he was assisting the Ferrovial/Laing O Rourke JV with the Northern Line Extension project. Kieron’s communication skills quickly shone through. His ability to convey candidly and accurately his and his client’s expectations and requirements made my job much more simple and straightforward. Kieron was an absolute professional but his personable character made dealing with him easy. Like dealing with an old friend.”

Barry Beavis – Sharpfibre Sales & Marketing Manager

Kieron has a demonstrable experience in delivering complex major projects. Over the time we worked together at London Bridge, I found Kieron to lead by example, always with the end goal in mind. He was a valued member of the Commercial team, who always sought collaborative solutions whilst not being afraid of doing the hard yards. I wouldn’t hesitate to work with Kieron again.

A. Freemantle – Costain Limited Senior Commercial Manager

I have worked with Kieron in the past and found him to be an imaginative, motivated, professional who played a key role in the team, he is generous with his time and knowledge and played an active mentoring role with our graduates which helped in up skilling our team.
