Why Use Gilcon

At Gilcon we have a “can do” attitude. Our solutions are always the best value for money. Our turnaround times for design and documentation are fast. During construction, we will always be available to take enquiries and give the necessary advice when it is required.

A real point of difference with Gilcon is response times, we answer emails fast, return phone calls promptly and general turn around times for all work is very quick.

You get a much better service from Gilcon than you can get with the larger consultancies.  Don't be fooled by their claims of prestigous projects.  Many are the equivalent of sweatshops with inexperienced engineers pumping out excessively overkilled designs and charging their clients top dollar. 

With Gilcon, you get well thought out designs from engineers who have worked with builders and clients for years to come up with the best engineered solutions.  If the builder has a different idea on how to carry out the construction, we are always happy to discuss and revise the plans.
