We have collaborated with Tecon for over 20 years on a wide range of commercial projects and have consistently found them to be professional, reliable, and innovative in delivering certification solutions. Their expertise forms a vital part of the design process, and their input continues to add significant value to the successful delivery of our projects.
We've been using Tecon for many years for all our architectural projects, from tiny verandahs to $30m health centres . We find them totally professional, reliable and responsive. They charge reasonable fees that match the services they provide. They have recently added access consulting services to their offering which is helping us even further. I'd highly recommend Tecon to businesses and householders.
