Rob Stewart

Rob is a Chartered Structural Engineer, he joined the practice as a Director in 2013 after having spent five years on the Island managing the structural department of a large design and build developer. This role involved the design of several large residential and commercial projects, with an emphasis on load-bearing masonry construction, RC transfer slabs, and piled foundations.

Prior to relocating to Jersey, Rob has had a varied international career spanning over 15 years. Having spent his formative years working for a large consultancy in London, he moved to Spain to work with a high-profile architect, designing a range of projects from sculptures to movable bridges.

He then moved to the USA to work for a large structural engineering consultancy, gaining valuable experience in areas such as high-rise, earthquake engineering, and post-tensioned concrete.

Rob’s career path to date has therefore resulted in him having a well-rounded and broad scope of experience, which is well suited to the varied demands of working within the practice. He also likes to keep a strong emphasis on the latest analysis and design software, including finite element analysis and building information modelling, (BIM).

Rob is kept busy raising a young family, but is also a keen golfer, and a Certified Checking Engineer under the registration scheme operated by SER.
