Overview

2.1 Background
• This project seeks to address structural and infrastructure issues in ancillary buildings which were not incorporated in a substantial rebuild of the school’s teaching spaces in 2014.
• In the longer term, it is envisaged that Block C will undergo interior refurbishment following the current reroof and cladding repairs.
• Project consultants are:
o Project Manager: Architects 44 Ltd
o Lead Designer: Architects 44 Ltd
2.2 Required solution (method and approach)
a. The Contract Works required are:
i. Block C: Work would involve removing the existing roof and installing new trussed roof structure to match the balance of the school buildings. Install new spouting and take rainwater to storage tanks. Undertake repairs to the exterior cladding and joinery.
ii. Block D: Remove rotten window, frame up and clad to match existing vertical weatherboard.
iii. Site: Upgrade Water Supply
o Install a 200m3 timber water tank beside the caretaker’s sheds as the primary water source.
o Connect all 7 of the existing concrete water tanks together as the initial rainwater collection tanks.
o Pump from these tanks to the new timber tank.
o Filter only the water that the school is using for daily use, rather than currently filtering all water taken to the storage supply tanks.
iv. Site: Connect Block AD (Toilets) stormwater drainage and site drainage
o The existing stormwater is piped to the school water storage tanks, but there is not sufficient height difference between the two locations and the water overflows onto the ground around the toilets.
o It is proposed to connect into a stormwater system taking the water to waste.
o Surface flooding occurs at the western end of Block AE. It is proposed to provide drainage to this area to take the surface water away.
v. Block AE: - Science Lab Upgrade
o The existing fume cupboard cannot be used. Subsequent to installation, the flue was removed.
o The project will replace bench in the fume cupboard and reinstate the flue.
o There is currently no gas to the science lab. The project will install a gas line from a gas bottle feed complete with gas valves at the bench and master shut off.
vi. Block H Fire Exits
o Reorient and reconfigure the fire exit doors to shorten escape paths.
o Install a new sink bench in the Clean Materials room
vii. The Contractor will be engaged through a Medium Works Contract. No Contract related tags will be considered.
