The PRO Structures Team


Founded in 2007, PRO Structures offers civil and structural engineering for residential, office, public sector and commercial buildings. A rapidly growing company based in Bristol, we have six engineers ranging from students to directors on our technical team as well as a business services director and admin functions, while also benefiting from the accumulated professional experience of a few trusted sub-contractors and draughtsmen. We work closely with highly experienced and trusted civil and geotechnical engineers where appropriate, to enable us to offer a full service. The team looks forward to welcoming you, and to helping you with any structural design needs you may have.

Exacting standards combined with added value

Our aim is always to offer the highest professional standards combined with excellent value and a no-nonsense approach. We take pride in developing long term relationships with our clients – who are, in the main, small to medium sized architecture firms in the South West and Midlands, and national-level house builders with offices in our region, along with industry specialists and related consultancies – and are happy to go the extra mile to ensure you get the structural solutions you need, going beyond simply meeting budgetary and time constraints.

We work on the structural design for both new build and refurbishment projects, and are specialised in designing for change of use, primarily on conversions from offices, retail, agricultural or light industrial premises to residential. In all cases, our goal is to work in partnership so that we fully understand your needs, and can solve problems and often advise on design and build models which will not only be aesthetic when completed but can save both time and money during the construction phase.

Working in partnership

“As part of our ongoing search to expand our supply chain, the addition of Ron and his team at Pro Structures has bolstered our ability to integrate with and perform on prestige projects. These range from smaller industrial units with complex dynamic requirements through to the construction of our larger projects such as Royal Wharf, Europe’s largest privately funded residential development. The broad range of skills within Ron’s business are an asset to ours.”

PRO Structures is run by director Ron O’Connor, a fully qualified and chartered structural engineer with 25 years’ post-graduate experience under his belt. Ron has a wealth of experience on projects both large and small, gained within the UK and the Caribbean, and a proven track record in successful project delivery from scheme design to final construction. He acquired a sound structural engineering grounding as a graduate with Jenkins and Potter before moving to work for larger, multi-disciplinary consultants such as EGP, Mouchel Parkman and WSP in Bristol.

Here he ran structural teams to deliver cost effective design solutions on projects as diverse as hospitals, colleges, business parks and motorway service stations. Ron then spent three years in Barbados as a senior engineer for David Lashley & Partners Inc, where he worked on prestigious projects such as the Regional Headquarters for the Royal Bank of Canada. Before deciding to start PRO Structures, he worked in the residential sector for Hydrock with small and large developers on schemes ranging from one to up to one hundred dwellings.
