Edinburgh Napier University
This Hyperbolic Perabaloid timber structure was always going to be a challenge in construction techniques for both the metal works from C.E.L Ltd and the carpenters. Working in partnership with specialist structural timber engineers Cowley timber a design was approved by architects BDP which saw the timber structure initially covered using cold applied bitumen coating by Grace Ice and Watershield before the final weathering envelope of Titanium shingles where laid upon it.
The Titanium shingles produced where of a general size of 720 x 500 mm and had to be produced to the most exacting of standards by the C.E.L factory fabrication team if the installation was to be successful. Working with titanium was always going to prove challenging, not least the fact that the product had to be purchased directly from the American producers before it was shipped to Japan for rolling to its final 1mm thickness.
The design considerations for the installation had to take into account not just the varying pitch of the installation, which was from almost vertical to almost flat and also upside down, but also the very exposed location of the University stood high above Edinburgh City. This process of design consideration was thoroughly worked through with partners Cowley timber and architects BDP and has achieved 100% success even when upside down.
