My technical work included unitised curtain wall fabrication drawings and installation instructions with isometric views and 3D-exploded views to illustrate assembly sequence. I reworked and corrected external contractors’ detail drawings for a blast enhanced door system as well as bid detailing and tender compilation including thermal modelling of new extrusions and thermal analysis calculations on new façade details to prove performance compliance with Building Regs, Document L. I detailed new aluminium extrusions taking account of materials properties governing design characteristics.
