Our Innovative Solution

Drawing on over 25 years experience in custom industrial buildings, the team at Techspan tailored the design, engineering and manufacture to this 40m wide x 94m long x 8m high facility to suit the exact needs of their client.

The main structure of the building consisted of a structural steel frame including 40m roof spans that required no centre column support – maximising the usable floor area and accessibility around the plant.
The building was designed, engineered and manufactured to meet high cyclone rating.

The project incorporated penetrations in the roof, along with a custom support integrated into the main structure in order to house the particular HVAC system.

A large cantilever awning was created over the side access door to allow all weather goods inward/outward and provide addition cover for their external tank system.

To meet quality assurance requirements, Techspan provided Inspection Test Plan (ITP) and Manufacturer Data Report (MDR) for all components of the project.

2 tone external colourbond cladding features were used to achieve an architectural aesthetic to the front elevation of the building.

Techspan were extremely proud to support Alpha HPA to achieve a positive outcome for their Gladstone facility and we look forward to seeing Alpha HPA continue to lead the way in their industry.

Manufactured to Australian standards. Designed for purpose. Engineered to perform.
