Page 87: SET- OUT FOR SUCESS
Bennett + Bennett are experts in providing specialist surveying services for major construction and infrastructure. Having partnered previously with Multiplex on various high-rise projects throughout Brisbane and the Gold Coast, the company was again engaged to provide works for the 1 William Street development.
The scope of works included:
• Set-out of the structural elements for each floor.
• As-constructed surveys of services, structures, holding down bolts, lift core and slab floor edges.
• Various cadastral services including identification surveys, boundary realignment surveys and volumetric easement surveys.
• Lease surveys for each tenant across all floors and.
• Survey of final constructed building height including spire – 266.35m (AHD).
A challenging, yet interesting aspect of the development was the control of the split level core. The building core was constructed in two parts, with two separate jump systems that had to remain connected and in unison with each other. They required high level vertical monitoring to analyse and register any compression.
Bennett + Bennett provided highly accurate monitoring of the building brackets on each floor, whilst also controlling the construction of the complex steel roof structure, which is five floors high. This also included the position and erection of the 90m high spire.
The team also undertook extensive observations of the steel awning structure at the front entry to the building to look for traces of structural movement. This survey was conducted using laser scanning to form a 3D point cloud for accurate meshing and defining of the structure in order to compare the scan with the original structure position.
“Working with Multiplex on this landmark project provided unique challenges and opportunity for our company. We are proud to have delivered high quality solutions and strong results, which enabled us to demonstrate our versatility and new services within a large-scale development,” said Craig Wood, Director / Brisbane Office Manager.
Established in 1968, Bennett + Bennett has a wealth of knowledge and experience that puts them at the forefront of the industry. The company currently operates from five office locations throughout Queensland with the capacity to service locations Australia wide. Capabilities include surveying, town planning, laser scanning, photogrammetry and titling.
