Our Services

Building physics, mechanical, electrical and public health engineering

We offer a diverse range of services, from traditional mechanical, electrical and public health engineering to specialist building physics, sustainability and environmental design services.

We are able to draw on our extensive experience, to provide professional and comprehensive advice and deliver client focused and cost conscious engineering solutions.

We use cutting edge technology and industry leading software packages to carry out complex, dynamic simulations and our engineers are trained in a range of CAD and BIM packages.
