Infinity, Broadbeach

Soaring 39 levels above the heart of Broadbeach, Gold Coast. ASP Piling and Australian Dewatering Systems provided the foundations for this magnificent building.

Horizon Apartments, Newcastle

This new development on Honeysuckle Drive in Newcastle is another key project for ASP Piling and Australian Dewatering Systems in the Hunter region. We have provided sheet piling, anchoring, bracing and dewatering systems for this high-rise project.

Sinclair Apartments

One of our recent projects with Mosaic is Sinclair Apartments, located along a main arterial road in East Brisbane.

This project involves foundation piling, sheet piling (including ground anchors and deadman piles), together with a dewatering system and management plan.

Burleigh Heads Mowbray Park SLSC

This small project involves sheet piling for a unique shaped site. Extensions to this existing building are to accommodate extra storage, larger kitchen and outdoor dining area along with a new lap pool and terrace.

With a total of 60L/M this site is anchored and internally propped. We also are providing the dewatering services for this site.

Mackay NBN Tower

ASP Piling completed this five week job consisting of 58Lm of sheet piling, and dewatering services. Due to the location of the tower, 3 sides of the sheet piling were required to be 1m above ground for croc protection during construction.

Located adjacent to an environmentally sensitive wetland, on site dewatering & filtration was crucial to the success of this project.

Cosmopolitan Cotton Tree

ASP Piling was contracted by Construction Control for the piling and dewatering of The Cosmopolitan in Cottontree at Maroochydore. The large parkland and waterfront site has a basement footprint that spreads two street frontages and adjoins the two towers being built. A total of 143 apartments will be spread over the two seven-storey residential towers.

We provided a range of options to our clients based on engineering, cost and site requirements and constraints. A combination of piling options was employed for the retention and foundation solutions, along with Australian Dewatering Systems site dewatering and environmental services.

The secant piling option was used for the section of basement perimeter with a 6-storey commercial building abutting the ‘Cosmopolitan’s’ boundary. Approximately 10-metre deep scant piles were installed with temporary anchoring. Sheet piling options were used for the remainder, a variety of depths and profiles being used based on basement requirements with the two towers having different basement depths. The sheet piles ranged from 6 metre sheets to over 10 metres long with the associated anchoring and removable whalers were used.

Foundation Piles were installed by ASP Foundation Piling across the site and for the crane base. Over 200 CFA piles were installed with our SF65 Soilmec piling rig.

Australian dewatering systems installed a perimeter spear system around the boundary of the site. The dewatering was installed and commissioned in a staged process as the site was excavated. A deep well system was installed to ensure the system would cope with the dewatering requirements as the basement level was excavated below the natural water table depth. In addition to the dewatering equipment, a filtration unit and sedimentation tank were needed and based on electricity availability a fuel cell and generator for a short period. Further, into the project, an Iron Remediation Tank was needed according to the levels indicated in the monitored discharge water. As always, the site had a dewatering management plan in place and compliance monitoring throughout the discharge process.

Mercato Byron Bay

‘Mercato’ in Byron Bay is leading the way in the area for environmentally friendly commercial space, looking to have a five-star green star rating for the retail and dining precinct. Azzura Corporation engaged Hutchinson Builders for the construction of Mercato in Byron Bay. ASP Piling was contracted to install the retention walls and foundation piling for the basement, and Australian Dewatering Systems for the dewatering of the project.

ASP Piling’s ability to use a combination of piling options to suit a variety of requirements on one site was brought to the fore at Mercato. Hutchinson builders were required to minimise disturbance to roadways and neighbours, whilst allowing the largest basement car-parking footprint possible. ASP Piling’s engineers worked with our clients to come up with a design that incorporated a section of top-down construction, foundation piles, retention piles including both secant and sheet piles, and dewatering for the most cost and time effective outcome.

Top-down construction is effective when there is an inability to using anchoring or the ground-level slab is needed immediately. The bulk excavation can continue after the slab is poured, also limiting the need for bracing where the slab is fixed. A section of the Mercato site was needed at ground level throughout construction making top-down construction most effective. Given the overall area and ease of excavation for the remainder of the site, the more traditional bottom up retention and bulk excavation was used for the rest of the site.

Pre-existing buildings close to the site boundary meant that secant piling was used for retention where minimising ground disturbance was necessary. Sheet piling was then used where suitable to keep costs minimised. A total of over 60 lineal metres of secant piling and over 250 lineal metres of sheet piling, both ranging in depths of 7-8 metres was used for basement retention. Additional sheet piling was used for the lift pits. ASP Foundation Piling installed the foundation piles for the project.

Australian Dewatering Systems was engaged to ensure the site remained dry throughout basement construction. The installation of a spear system along with a generator, fuel cell and our environmental equipment, a dewatering management plan and compliance monitoring were all part of the services provided. In keeping with the environmental philosophy behind the Mercato project, ADS has installed a pH, Iron and Sed tank to ensure that all water discharged from site met or exceeded environmental and council standards for the duration of dewatering.

The Thornton Project Penrith

The Thornton project originally covered a 40-hectare site next to the existing Penrith city centre and train station. The overall concept was to develop a diverse housing development with high density units and apartment complexes close to the retail and transportation hub with further housing and community centres further out.

Many of the housing, infrastructure and open space works are completed and the mixed use and high-density areas closer to Penrith City Centre are well under way with a number of unit and commercial projects completed or nearing completion. The next phase of the development further from the centre comprising of additional units and housing are starting, with works to continue through to 2020.

Starting in January 2016 we have completed a combination of sheet piling, anchoring and bracing, on five different sites in the high density and mixed-use areas of the development for Moits, Dasco and Urban Apartments.

The sites have all required perimeter wall sheet piling as well as lift shaft and core retention. A total of over 1200 lineal metres of sheet piles and associated anchoring have been completed to date with profiles varying site to site based on client, engineering and geotechnical requirements. Piling depths have varied from 5 metres to 8 metres across the sites.

ASP NSW has supplied and installed over 400 lineal metres of sheet piling around the perimeter and lift shafts for Urban Apartments. The depths of excavation required averaged at approximately 6.5 metres. In addition to this, the Lord Sheffield Circuit sites have required dewatering, filtration and sediment tank hire. On one of the sites a generator was also required as the electricity supply wasn’t available to run the dewatering and filtration equipment.

Thornton Central is a three stage development of mixed use lower level retail and upper level unit complexes. There will be three nine-storey buildings totaling over 300 units in total. Stage 1 of the Thornton Central development required the installation of over 450 lineal metres of sheet piling for the perimeter and lift cores. ASP Piling NSW was contracted to Dasco and undertook the mobilisation, engineering, pre-drilling, installation of sheet piling, bracing and anchoring as required.

ASP Piling undertook the mobilisation, engineering, pre-drilling and installation of over 200 lineal metres of sheet piles around the perimeter as well as for the staircase and lift cores and crane base. The sheet piles were approximately 7 metres in length with associated anchoring and bracing used on the site. The anchors were then stressed to the engineering requirements to ensure the strength of the retention walls.

East Quays One, Emandar Group

Located on the waterfront at Biggera Waters on the Gold Coast, East Quays ‘One’ apartment complex was developed by Emandar Group. ASP Piling was contracted to provide over 120 lineal metres of sheet piles for this Emandar Group apartment development. The maximum depth of cut across the site was 3 metres. Australian Dewatering Systems was contracted for a block of 12 weeks for groundwater removal and environmental monitoring and management.
