Testimonials

“OCS Civil and Structural Engineers supported a recent residential extension project in South Wales, and their attention to detail and thorough approach stood out immediately.

The drawings and information were clearly presented, making them straightforward for contractors to work from. Throughout the build, OCS Civil and Structural Engineers were highly professional and responsive, which my client specifically commented on and appreciated.

While I was already aware of OCS Civil and Structural Engineers’ experience on larger scale commercial projects, it was great to have the same level of expertise and attention applied to a smaller residential scheme. I would not hesitate to work with OCS Civil and Structural Engineers again and look forward to working together on future projects.”

“OCS Civil and Structural Engineers supported us with a project involving the removal of a chimney to create an open-plan living space, as well as a loft extension with a large dormer.

They completed all the structural calculations to ensure the design was safe, compliant with building regulations, and specified the required beam sizes, masonry supports and foundation requirements clearly. During the build, OCS Civil and Structural Engineers were especially helpful in amending the calculations to account for unexpected site conditions uncovered by the builder.

This gave us real peace of mind throughout the project, and we were very pleased with the service provided."
