ABOUT US
Led by Mark Turner CEng BEng MICE MIStructE, Adelphi Consulting Engineers employ a team of experienced engineers and technicians who have decades of experience of delivering practical, cost effective Civil & Structural Engineering solutions across a broad range of sectors.
With particular expertise in the Heritage sector, our team have worked on World Heritage Sites, Scheduled Ancient Monuments and all grades of listed buildings. Using the latest 3D analysis, design and drawing packages, we also have a broad portfolio of work in new build and refurbishment of leisure facilities, commercial buildings, industrial sheds, all forms of educational establishments, hotels, exhibition centres and residential schemes.
We can engineer multi-million pound multi-storey schemes in the full range of structural alternatives; and we can survey centuries old masonry and timber structures.
​
While we work with many architectural practices, we have a sister company, Adelphi Architecture, and can offer a unified architectural and engineering design with the attendant benefits that this approach can bring for a client. Adelphi Architecture is led by Joanna Pullan, a RIBA Accredited Conservation Architect, who also has a broad range of experience in other sectors.

IN MEMORY OF OUR FOUNDING DIRECTOR:

Bruce Horsburgh 1956 - 2025
Bruce Horsburgh was Adelphi Consulting Engineers' founding director. He was an inspirational man who was the first conservation accredited chartered engineer in the northeast of England and a former Cathedral Engineer to Durham Cathedral.
Bruce was born in Malta to a naval family, and brought up in the west end of Newcastle. He became a draughtsman on leaving school at 16, and eventually went contract alongside many of the friends he maintained until the end of his life. He was one of the first draughtsmen to embrace CAD, but Bruce didn't rest on his laurels. Through the late 90s and into the 2000s, he progressed from draughtsman to become a Chartered Civil Engineer. In 2018, he achieved his ultimate goal of founding and running his own successful business.
More than that, Bruce was a loyal friend who put his family and friends before himself. He was very popular amongst those who knew him personally and professionally, and is deeply missed by those of us who were fortunate enough to be close to him. He lives on in our hearts and will always be remembered with a smile.
