Diales has turned five!

Five years ago, Driver Group announced a new approach to the delivery of construction Expert Witness support services and Diales was born. A service that would bring together world-class experts in the fields of delay, quantum, and technical and provide support through a dedicated team, when clients needed it most.

Diales launched with twelve highly-regarded and highly-skilled experts, with published authors[i] John Mullen and Peter R Davidson amongst them. The team grew as launches followed in Asia and the Middle East and more experts joined them across Driver’s worldwide network of offices from Australia to Canada.

Today, the number of Diales experts is closer to 40. The technical team, headed by Stuart Macdougald-Denton, has a dedicated team of researchers, engineers, and architects; many of whom regularly share their wisdom and experiences in the pages of the Driver Trett Digest as well as through social media posts and presentations (a couple can even help make cars fly![ii]).

For a five-year-old, Diales has thrived and developed well, adding further new services and skills and supporting a diverse and fascinating range of clients and disputes around the world. Most recent additions include asset valuation expertise in the shape of Gary Richards.

Head of Diales and Global Chief Operating Officer for Driver Group, Mark Wheeler said:

“The last five years have passed very quickly, and I am delighted to see Diales exceed our expectations year on year. The recent addition of the highly successful technical team has underlined our commitment to this service, and we are excited about the future with new services planned for the next two years…”
