Rapid Growth Project 6 Marine Works 

Customer: BHP Billiton Iron Ore Pty Ltd

Location: Port Headland, Western Australia, Australia. 

Contract type:  Construct only

Construction Period: 1.5 years


The contract involved the construction of two additional iron ore export berths at Nelson Point inside the harbour at Port Hedland, Western Australia. The scope included 17 berthing dolphins, 16 topside modules and 300 piles.

Following the success of the Rapid Growth Project 5, PSICG was awarded the Rapid Growth Project 6 Marine Works contract by BHP Billiton Iron Ore Pty Ltd in May 2010.

The McConnell Dowell team maximized the use of modularisation to improve construction efficiencies, reduce on-site labour and ensure a quality outcome. A Heavy Lift Vessel was mobilised to bring large wharf deck modules from China to site and lift them into place. PSICG Batam fabrication facility and Perth precast yard also contributed to the modular solution, with temporary works items and precast wharf deck panels.

The project, completed in September 2011, has maintained the positive relationship between McConnell Dowell and BHP Billiton in the delivery of key port infrastructure to sustain expansion from their Pilbara operations.


  

Wyndham Vale Train Stabling

Customer: LXRA and VLINE 

Location: Melbourne, Victoria 

Contract type:  Construct 

Construction Period: 3 years


Under the Western Program Alliance, PSICG are currently constructing the Wyndham Vale Train Stabling Facility, north of Wyndham Vale Station.  

The facility will be completed in early 2020 and will replace the existing stabling near Footscray, to be removed as part of the West Gate Tunnel Project.  

The project will involve construction of a stabling yard capable of holding six V/Line trains, driver facilities and a bypass track connected to the Geelong line.  

The Alliance is well-placed to undertake these works in the west, having recently completed their first two level crossing removal projects ahead of schedule, and also recently commencing the Aviation Road level crossing removal project in Laverton. 


  

Dryandra Road Underpass


The Dryandra Road Works contract is a significant structural element of the New Parallel Runway (NPR) for Brisbane Airport Corporation (BAC). 

The Dryandra Road Project is a reinforced concrete 4-lane underpass structure, supported on approximately 700 precast concrete piles including 1.5km of roadway, extensive utilities works, including a full underpass fit out with portions of taxiway and airfield road mounted atop the underpass structure. 


Key to Success  


The underpass will allow vehicular access either side of the new linking taxiways, which will be constructed as part of the NPR project to connect the new runway in the west to the passenger terminals and existing runway system in the east. PSICG has included sheet piles in the solution, which results in reduced excavation, better construction access and stability.  

Our temporary sheet piling solution is simple and presents the project team and BAC with low risk through reduced marine mud settlement and reduced future taxiway settlement. This, coupled with the installation of precast piles from above the water table, removes five (5) weeks from the critical program and further risk associated with instability, settlement and inundation.  


The Challenge

  

  • Methodology  to mitigate risk, and based on well thought out and tried and tested      solutions
  • Understand documentation required, including Approvals - and set up to deliver this.
  • Right team available- right team in the right positions
  • 3rd  party interfaces, effective access and egresses, services, Telstra, ASA & PUP installation & commissioning and any downtime, causing disruption to Airport Users.
  • Very large concerns around windblown sand, line of sight and temporary lighting.



The Solution  


Our construction methodology is safe, simple and minimal risk.  

Our sheet piling solution reduces the overall excavation volumes, and will: 

  • Reduce the underpass excavation by 61%, and result in 66% less backfill quantity.
  • Remove the constraint of a linear program as access is possible along both sides of the entire underpass.
  • Remove dewatering installation, dewatering draw down, and PASS treatment from the      critical path.
  • Remove the risk of future settlement of the taxiway as the material adjacent to the underpass remains undisturbed.
  • Eliminate stability issues of the open excavation embankments, and reduces      susceptibility of the Project to weather events.
  • •Allow services along the new alignment as an option, to be installed ahead of the traffic switch to Dryandra Road, removing further program risk.


Our dewatering solution, paired with the sheet piling solution, will deliver: 


  • Reduced duration and removal of this activity from the critical path
  • Reduced cost by reducing the number of dewatering wells 
  • Reduced dewatering volume by a third to 2.5 ML /day as the area being dewatering is      reduced by 69%.


Our precast piling solution of installing piles from above the water table, shown below, will result in:

 

  • Earlier and unimpeded access for the piling rigs to install precast piles
  • Effective and efficient delivery of piles directly to the piling rigs
  • A smaller piling platform that enhances rig stability and reduces heaving risk from the marine muds
  • Reduced piling vibrations thus reducing the risk of destabilising the excavation sides
  • Reduced excavation area by 69% removing the risk of excavation impoundment 


By installing precast piles from +4 m AD, earlier commencement of the piling is achieved. Risk to the program is further reduced by working above the water table, on the sand mattress, therefore mitigating any stability issues of the excavation, including and likely heaving of the working platform. Similarly, the Project is not materially affected by wet weather.  

Our sheet piling solution will remove the unpredictable activities of dewatering installation, dewatering drawdown and PASS treatment approval being removed from the critical path. The sheet piling also makes the site roads adjacent to the underpass possible, which ensure access along the entire underpass, removing the constraint of a linear project due to access issues. This will result in a flexible program, delinks over 80% of the activities, and allows the ability to accelerate all or parts of the Project if required. 

These well considered construction methodologies deliver a flexible program, while making the Project resilient to weather events resulting in surety of program.  


  

Swanson Dock East Berth 1

Customer:  Port of Melbourne 

Location: Melbourne 

Contract type:  Fixed Price Lump Sum, Construct only, 

Construction Period: 2 years

Project Capabilities

Civil Marine


PSICG was engaged to remediate and strengthen the Swanson Dock East Berth One wharf within the Port of Melbourne. 

The wharf consists of a concrete slab on ground that is founded on timber piles with earth back fill being retained by a sheet pile wall at the rear half of the structure and steel piles at the front half. 

The structure was built in the 1970s and over time the tops of the timber piles have degraded and some of the earth back fill has sunk. This has resulted in the subsidence of the concrete wharf slab and crane rails which impacted upon the ability of the ship to shore cranes and straddle carriers to traverse the wharf within operating tolerances. 

To arrest further subsidence, the wharf required strengthening. Releveling works were also undertaken to match the deck and crane rail levels to the adjacent terminal infrastructure at the rear of the wharf. 

To achieve this, the scope included installation of through deck piles, deck and crane rail re-levelling. The Port of Melbourne also included, general remediation works such as removal of defective concrete, crack repair, and fender beam rehabilitation and replacement of fenders within the Contract scope. 

The project was conducted within Australia’s busiest container terminal facility directly adjacent to fully functioning stevedoring activities. 

This resulted in the works being confined to a small footprint in order to minimise any impacts to the terminal operator. 


COLLABORATIVE CONTRACTING 


The project had two distinct phases: the Early Contractor Involvement (ECI) Phase which included early procurement engagement, and the Site Construction Phase. 

The Project was a collaborative, construct only contract, working closely with the client, Port of Melbourne, and their engineering consultant AECOM. 

The ECI phase had a two and a half-month duration during which PSICG worked closely with the Project team to identify design and construction innovations. These innovations were market leading resulting in significant project benefits realised by stakeholders. 

A key deliverable recognised during the ECI planning was to ensure that the construction works were undertaken and sequenced such that they did not impact upon the terminal operator outside the construction footprint. 

The detailed sequencing undertaken within the ECI ensured this deliverable was achieved, and provided an accelerated start on-site following on from the main Contract award. 


COMPLEX CONSTRUCTION & SEQUENCING 


The construction phase was principally focussed on executing the works within the site footprint safely, without interrupting terminal operations. 

To achieve this goal, the project team regularly engaged with the various stakeholders to develop the construction program. This agreed program was then strictly adhered to by the project team. 

Consistently honouring the commitments made during the ECI phase helped to maintain and foster the positive relationship between PSICG and the project stakeholders. 


INNOVATION & EXCELLENCE 


During the detailed design phase of the ECI process, it was discovered that the deck could not be loaded with heavy construction equipment for a significant period of the project. This posed a challenge to understand how the through deck piles could be installed with this restriction. PSICG temporary works designers, in conjunction with the nominated piling subcontractor, developed a grillage beam arrangement that transferred the loading from the piling temporary works onto strong points within the deck footprint. This ensured the works could remain confined within the site footprint whilst achieving program. 

The significant amount of remediation works required to the existing fender beams presented a key safety and environmental challenge. Defective concrete had to be removed and reinstated along the vertical face of the quay-line (front and back) and along the soffit. The project team identified the key to ensuring the works could be executed safely and efficiently was by ensuring safe stable access was provided to the workforce. To achieve this, bespoke fender access frames were designed and fabricated. These frames provided safe access and environmental capture of demolition materials.
