The DGA way
DGA brings all the traditional QS skills you would expect from a professional RICS firm. Our approach, however, is radical.
Construction cost analysis is no longer just about money and capital cost – it’s about understanding value for the client. It’s about social value, environmental value, performance and happiness.
Life is good and you can’t help smiling.

Our Mission: To deliver accessible, relevant construction advice to clients and our wider community.


Our Vision: To change our construction world and our role within it – one project at a time.
“Our team is our future. I am fortunate and honoured to work with, rely on and spend time with this amazing, talented group of people.
They are diverse, challenging, dynamic, motivating, inspirational. They make life fulfilling and enjoyable. Every day is different.”

Derek Gough MRICS
After creating DGA at his kitchen table nearly 30 years ago, Derek has amassed many years of experience in the quantity surveying and construction industry sectors.

When he isn’t on the golf course, Derek remains a vital member of the team, working closely with our apprentice and assistant Quantity Surveyors especially.
“Expert in civil engineering, a pretty good golfer and our inspiration… Oh! and a lifelong City fan.”
