An enabling works contract was undertaken to divert existing belowground services and prepare the site. Unsuitable ground underlying the site was excavated and replaced with imported structural fill.
A geophysical survey to screen for unexploded ordnance remaining from air raids on Clydebank during the Second World War was also undertaken. Fortunately none was discovered. Shallow in situ reinforced concrete semi-raft foundations were incorporated to minimise excavations and simplify perimeter details, with a power-fl oated finish providing the wearing surface. The superstructure comprises a singlestorey two-way sway frame structure with rigid moment connections to negate the need for vertical cross-bracing within the wall zones, allowing minimal structure within the architectural wall build-up.
Efficiency of fabrication was achieved by maximising repetition, with two of the three structures being identical and the third structure being a mirror image of them. Blockwork walls were adopted at low level to provide robustness within the workshops, with carefully coordinated lightweight cold-formed sheeting rails and purlins supporting the architectural cladding systems to the walls and roof, while facilitating the translucent light box features. Full-height blockwork division walls were provided between units to give effective fire separation. External areas were remodelled to enable vehicle access while enhancing access to adjacent properties, via a redesigned adoptable road network. Car parking and service yards were constructed in air-entrained reinforced concrete, providing a robust hard-wearing surface, which contrasts with the adjacent macadam pavements, providing clear delineation between private and adopted areas.
