Engineer / Architects

CRTC offers the architect, engineer, designer and contractor a complete design service to help take advantage of the obvious material and construction savings that timber trusses and Ecojoist floor systems can bring, particularly with the increase in design complexity which render conventional framing techniques unsuitable.

In order to streamline the workflow from exchange of information right though to the manufacturing process we provide the following design guides.
