Guildford Grammar School Boarding House Accommodation
Property
- As the proposed stormwater drainage trunk main realignment was proposed to run along Terrance Road with long sections of boring under existing trees and relocation of a power pole, Pritchard Francis shifted the alignment inside the school site, allowing the contractor to clear trees and undertake the full extent of works with an open cut trench with significant cost savings.
- A key structural design achievement for this project was the economical resolution of large span buildings. Due to site restrictions the optimal arrangement for the accommodation units required spans over 15 metres as well as large building cantilevers. Typically spans of these length would require a significant premium in construction cost and special requirements. Pritchard Francis developed an innovative design methodology, incorporating AFS walling as a deep beam, in conjunction with precast hollow core planks which allowed the long span solution to be delivered hundreds of thousands of dollars cheaper than a conventional solution.
- There is an existing council stormwater drainage trunk main that runs from the road reserve through the site and discharges to the wetlands. As the existing pipe clashes with the proposed structure, Pritchard Francis were required to assess the upstream catchment and design a realignment of the pipe to enable the removal of the existing pipe and easement from the development site.
- As the proposed development site is on the banks of a functional wetland zone that feeds into the Swan River, Pritchard Francis were required to incorporate strict stormwater treatment and attenuation measures into the design in order to gain development approvals from City of Swan and the Department of Biodiversity, Conservation and Attractions.
Pritchard Francis was engaged to provide civil and structural design for a new co-education boarding house incorporating over 200 beds, an administration area comprised by a reception, head of boarding office, interview room and a parent/student lounge.
The proposed development site is located on the banks of a functional wetland zone that feeds into the Swan River creating significant civil and structural challenges that had to be addressed.
The civil solution incorporated strict stormwater treatment and attenuation measures into the design in order to gain development approvals from the City of Swan and the Department of Biodiversity, Conservation and Attractions.
Due to the soil conditions in the flood plain, a structural solution which included significant piling through wetland conditions as well as allowance for potential future flooding landing was incorporated into the design.
