Belpile were engaged to undertake design and construction of crane foundation piles within an existing heritage building, working within headroom as low as 2.5m. Our in house engineering team undertook re-design of the proposed scheme to ensure suitability for our Hutte HBR203 machine. The piling equipment was lifted into the basement via crane through multiple… Read more
Belpile undertook design and construction of some 657 piles across 12 structures for the new CPG2 plant. Numerous design challenges were addressed and overcome including variable residual soil (lateritic) conditions, static and dynamic structure loading, soil downdrag loads, long terms consolidation and group effects. Belpile undertook design verification through 3 No static load tests and… Read more
Cockburn Gateway Stage 2 involved an extension of the existing shopping centre complex to provide additional retail tenancies as well as basement and rooftop carparking. Redesign from bottom up to top down methodology resulted in significant program and cost benefits which ultimately made the project viable. Belpile assisted in development of the top down foundation… Read more
The 500 Hay Project is the largest top down construction project undertaken in WA to date. Belpile were instrumental in the development of the top down design for this project, which comprised a 3 level basement in the busy urban environment of Subiaco. The piling scope involved some 500 contiguous piles of 450mm/600mm diameter and… Read more
Belpile provided a design and construct alternative for the piled foundation scheme along the northern promenade at AFC. This involved re-designing the proposed driven pile system to a CFA solution to provide a lower impact installation in terms of noise and vibration. A drilled pile solution was more suited to the construction environment, with numerous… Read more
This development involved construction of a 2 level basement on a narrow, sloping block, with a piling scope comprising contiguous piling to boundaries and internal foundation piles. The presence of adjacent basements precluded the use of temporary ground anchors, instead requiring a detailed temporary steel propping arrangement to be developed and managed by Belpile in order to minimise risk of movement induced damage to adjacent structures. The position of the site at the top of the Kings Park escarpment also required detailed analysis of slope stability/pile interaction issues in both static and earthquake loading scenarios. The complexity of design was a key feature in Belpile being awarded this piling package.
The Port Pirie Regional Sports Precinct involved construction of a new aquatic centre facility, function centre and light towers on soft alluvial clays. Due to the high groundwater table, a CFA solution was preferred. Belpile provided a design and construct alternative for the piled foundation scheme, which was offered to the local council during the value management phase, providing a significant cost and time saving to the project. The re-design to a smaller diameter pile across the project also allowed the use of smaller piling machinery, which suited the underlying soft subgrade and minimised the design thickness of the piling platform. It also reduced the spoil volume to handle on site which was significant in an acid sulphate soil environment.
The Claremont on the Park project involved construction of a two level basement associated with a large scale residential development in Claremont, WA. Belpile were successfully awarded this project due to a design and construct alternative utilising a smaller diameter pile and increased number of temporary ground anchors. This resulted in a solution with lower materials requirements and minimised the spoil volume for the primary contractor. The variable limestone strength and depth required the use of both conventional CFA and cased CFA (double rotary) techniques. The cased CFA system was employed where high strength limestone was encountered and provided improved positional and verticality tolerances.
Belpile were engaged on a construct only basis to undertake CFA piling works on a bridge replacement in Harvey, WA. The project was undertaken in accord with Main Roads WA piling specification 814 and required installation of 750mm diameter piles to significant depth with heavy reinforcing profiles. Working on the slopes of an existing watercourse, Belpiles’ lighter piling equipment was key to minimising earthworks requirements for the main contractor. Belpile ensured safe operating condition by undertaking an independent slope stability assessment in house using Oasys Slope software. Pile capacity was verified through two high strain dynamic load tests undertaken with a crane mounted 5t hydraulic hammer. Pile Driving Analyser (PDA) and CAPWAP analysis were undertaken to successfully prove the required design geotechnical resistance.
