BUNZL Office & Warehouse
Industrial
- Ultra-refined structural analysis, varying member sizing to suit wind directionality and loading. Savings resulted in an 80t steelwork saving worth $400k to the client.
Pritchard Francis were engaged to undertake the civil and structural design, documentation and site administration of the Bunzl Warehouse facility at Jandakot Airport, comprising of a 19,000m2 warehouse and 1,500m2 office.
As a result of the 2ha building footprint on the 4ha site, liaison and negotiations with Jandakot Airport were undertaken to relocate a road reserve stormwater basin to an alternative position. The road reserve stormwater basin was successfully redesigned and relocated in prompt time, enabling the site works for the building pad to proceed on programme.
Stormwater drainage was managed via two alternative methodologies, being pit and pipe to the new stormwater basin with Jandakot Airport’s permission, and on site retention for a 1% AEP storm event for those events on the hardstands and car park which could not be piped to the desired location.
An ultra-refined engineering design approach reduced any wastage from the structural steelwork and resulted in an overall steelwork tonnage of 10kg/m2 for the warehouse, which is around 20% lighter than comparable designs for a 14m high building.
