About Us

15 Years of Construction Experience

Fifteen years ago J.A.C. Construction realised there was a growing demand for a fabrication company to offer more than just steel installation. The need for structural alterations was being driven by Architects, Engineers and Developers so that the new contemporary opened space designs could be applied to existing buildings. J.A.C. offers a unique service to our clients, whether high end Developers, Refurbishment companies or self-build projects.

Steel Fabrication With our own fabrication team you will have the assurance of a fast and efficient fabrication service. +Enlarge image

From the design and installation of temporary works to the controlled demolition of an existing structure, we install pad stones, excavate pad foundations, and install re-inforced concrete. Once the temporary works have been removed, we will make good the existing structure leaving your project ready for fit-out.

We carry out underpinning and for the last five years have been installing basements as a specialist sub-contractor or main contractor. As a company, there are no alterations to the structure of a building that J.A.C. would not complete.
