We have the capacity to provide a range of services from conservative through to innovative to match your job needs and risk profile. We accommodate both large and small projects with flare and pride ourselves on “outside the box” thinking in order to produce creative solutions.

Although we are well aware of the need to be cost-sensitive, EDC does not cut corners. We aim to deliver work of a very high standard with an emphasis on safety in design.

Our experience in working effectively with councils means we can better help you obtain your design approvals.

We take pride in presenting cost effective solutions for enhancing the strength of existing buildings.
