Noble Park Zone Substation

Following the award of the Mentone Zone Substation Multiworks secured the delivery of refurbishment works at the Noble Park Zone Substation. The similarities between the two projects enabled Multiworks to capitalise on available economies of scale and to resource both jobs efficiently. The project works included:

  • Construction of a 22kV Control Room
  • Significant infrastructure works
  • Considerable installation of conduit runs
  • Resurfacing & reinstatement of roadway.

Toll Chemicals

Working within Toll’s primary chemical storage facility in Laverton, Multiworks were required to excavate and replace over 3000 m2 of engineered concrete paving. The site was to remain functional at all times and as such the works were broken into 3 stages. Straddle cranes, forklifts and delivery trucks frequent the site and hence interruptions to the sites operations were to be minimised as much as possible.

Multiworks worked closely with both Toll and Goodman to achieve an acceptable staging of works that minimised the impact on site operations and also returned the facility to full capacity as soon as possible. The project’s scope included:
  • Saw-cutting, excavation and removal of redundant concrete.
  • Testing of groundwater and soil.
  • Engineering and sign-off of reinforcement design.
  • New engineered concrete paving, approximately 3000m2
  • Saw cutting of construction joints and corking.
  • 3 Stages of work.
  • Concrete testing.
  • Reinstatement of line-marking and bollards.

Mentone Zone Substation

The Mentone Substation is situated on a site with significant space constraints. Multiworks successfully managed refurbishment works, including:

  • Construction of a 22 kV Control Room including a cable basement
  • Major upgrades to existing site buildings
  • Construction of a 220kV transformer enclosure
  • Over 700 lineal meters of trenching and conduit installation
  • Installation of an environmental drainage system.

FORD – Broadmeadows

This historic project comes about as Ford Australia sells its manufacturing plants, bringing to a close more than half a century of Australian motoring history and local car production. The project scope included civil, structural, mechanical, commissioning and HV electrical works required for the separation of common building utilities for the subdivisions of the sites.

Multiworks was originally engaged through ECI to provide input into the design constructability, methodology, staging and scheduling of the proposed subdivision projects at Geelong and Broadmeadows. After a formal RFQ Multiworks was eventually engaged as Principal Contractor, responsible for managing and coordinating the entire scope and the site of up-to 120 people.

At Broadmeadows, the new services to be constructed include domestic water, natural gas, fire services, stormwater and HV electrical up-to 5 meters deep.

Multiworks was the Principal Contractor responsible for managing coordinating the entire scope and the site of up-to 120 people.

Cawley Road Industrial Park

Working under a schedule of rates contract, Multiworks have been responsible for the upgrading of Cawley Industrial Park over the past 12 years. Originally a manufacturing plant the 35,000m2 of industrial building required substantial refurbishment including:

  • Repair of over 3000m2 of industrial pavement.
  • Recladding of buildings.
  • Maintenance of drainage, fire and electrical systems.
  • Creation of new landscaped areas and parking.
  • Creation of new internal offices and amenities.

Hastings Railway Culvert Upgrade

The work consisted of upgrading 7 ARMCO culverts located at Kings Creek (2 no 2400 pipes) and Warringine Creek (4 no 3600 pipes). At each location the culverts support one track with form part of the Frankston to Stony Point Line.

Multiworks was responsible to perform all works to apply a shotcrete lining for the full internal circumference of each steel pipe, apron slab and revetment wall.

Euroa Water Treatment Plant

Work comprised refurbishment of Euroa Water Treatment Plant Plant to enable sludge management geobags to be installed and commissioned. Works include an access road, earthworks, modifications to existing water supply infrastructure, pits, pipes, tanks, lagoon refurbishment, removal of asbestos cement pipe, drainage structures and a reinforced concrete slab for the geobags as well as a D&C component for a supernatant recycle water pump station and pump main.

Austrim Nylex Decontamination

This 4.5 hectare site in Coburg was originally used by Austrim Nylex for the manufacturing of plastic automotive components. Prior to the creation of a new public access road and subdivision into 36 industrial allotments, the site required extensive remediation of the contaminated soil and groundwater. The remediation process involved:

  • Removal and disposal of 30 underground storage tanks and associated product lines.
  • Removal of asbestos and demolition of approximately 5,000m2 of disused industrial buildings.
  • Excavation, remediation and reinstatement of over 40,000m3 of contaminated soil.
  • On site crushing and recycling of all concrete.
  • Facilitation and supervision of contaminated ground water with vacuum enhanced extraction technology.
  • Installation and commissioning of active skimming pumps

James Hardie Site Redevelopment

Multiworks was responsible for the remediation and conversation of the 15 hectare James Hardie asbestos processing facility. The conversion of the site into a industrial park was undertaken over 7 years and required special care in not disturbing the underlying contamination. The works included;

  • Installation of approximately 20,000m2 of geotextile fabric.
  • The importation and compaction of approximately 150,000 tonnes of engineered fill.
  • Construction of 3,500m2 of reinforced concrete road pavement.
  • Spreading and compacting of 10,000 tonne of recycled concrete hardstand.
  • Construction of 7,000m2 of engineered concrete hardstand
  • Significant drainage, electrical and landscaping works.
Multiworks now has since managed and maintained the buildings and land.

FORD – Geelong

This historic project comes about as Ford Australia sells its manufacturing plants, bringing to a close more than half a century of Australian motoring history and local car production. The project scope included civil, structural, mechanical, commissioning and HV electrical works required for the separation of common building utilities for the subdivisions of the sites.

Multiworks was originally engaged through ECI to provide input into the design constructability, methodology, staging and scheduling of the proposed subdivision projects at Geelong and Broadmeadows. After a formal RFQ Multiworks was eventually engaged as Principal Contractor, responsible for managing and coordinating the entire scope and the site of up-to 120 people.

At Geelong, the new services to be constructed within the existing manufacturing site include domestic water, sewer, fire services and stormwater buried up-to 6 meters deep.

Work onsite was consistently challenged by subsurface conditions as contaminated and erodible soil was spread throughout the site. As principal contractor Multiworks both managed and self performed the remedial works ensuring the safety of those onsite and the environment was not placed at risk.
