About us

Modulus is a chartered structural engineer and design consultancy. We provide structural design services, training, authoring, technical editing and have a specialist knowledge in the design of reinforced concrete.

Our aim is to provide a high quality, bespoke service for all our clients. At the outset of a project we will establish a clear brief, agree fees and realistic timescales. Even with the best intentions, unforeseen circumstances arise and should this occur we will discuss the options available so that an informed decision can be made before proceeding.
