Infrastructure Engineering aims to design the built environment around us, helping to create better places to live for our communities, by producing public realm space or transportation links to last long into the future.

Back to Services

In Design ID we specialise in delivering technical problem solving and holistic technical project management, to achieve our Public Sector Client goals, whilst leading Construction Teams in delivering efficiency, sustainable and environmental improvements for the same aim.

In each core sector we are driven by the same holistic engineering ability to see the bigger picture, where we have also applied more general infrastructure Health, Safety & Environment advisory roles such as Principal Designer, Project Supervisor for the Design Process (PSDP) and BREEAM Infrastructure Assessment.
