Service Station Acoustic Solutions from Modular Wall Systems
Caltex Guildford, NSW
Challenge
A Caltex service station in Sydney's west had to construct an acoustic and
visual wall to shield adjacent neighbours from the operational noise of a 24
hour Star Mart service station. Owing to an unstable existing retaining wall
between the construction site and neighbouring properties, the solution
needed to encompass a complex cantilevered post system to transfer
wind loading onto stronger areas of soil. An extended design life was also
a key requirement.
Solution
The GuardianWall system, utilising galvanised UB support columns,
was deemed suitable for this project. A unique GuardianWall solution
was quickly designed and fabricated by Modular Wall Systems to
ensure the residents were not exposed to construction noise.
The requirement for the top of our wall to meet specific height Reference
Levels imposed by Fairfield City Council resulted in significant
challenges when completing the footing foundations. However,
persistence and ingenuity resulted in a fully compliant project.
The final GuardianWall design was 1.5m - 3.0m high and 76.4m long, comprising
of 29 individual cantilevered posts and AcoustiMax™ 75 panels which
exceeded the required 20+RW (Weighted Sound Reduction Index)
acoustic values. A final lick of paint resulted in a highly professional and
subtly practical noise barrier with 40+ year design life.
Acoustic Qualities
All Modular Wall Systems products have acoustic properties
and are National Acoustic Lab tested and rated with reflective
panels achieving a 20+ dBA improvement and absorption panels
exceeding a Noise Reduction Coefficient (NRC) of 0.9.
