Pacific Steel Mill

Wastewater Treatment Plant | Otahuhu Auckland

BACKGROUND

Toll Holdings acquired a site in Otahuhu to develop a significant freight forwarding facility. In order to acquire the land required for the facility Toll had to construct a new wastewater treatment and cooling facility for Pacific Steel in order that they could release the land on which their existing treatment plant was sited.

Smith and Loveless design and supply process units for water treatment plants, however they do not usually provide installation services. In this instance the client required a turnkey solution for the project, hence Smith and Loveless contracted Anglo Tasman to assist with project delivery.

SCOPE OF WORK

Anglo Tasman were engaged during the design stage of the project to develop the electrical scope of works including the design of the motor control centre and site cabling. Our Scope of Work included the following

  • Project Management and Supervision of design, installation and commissioning of plant
  • Development of process and instrumentation details and functional description
  • Motor control centre design
  • Containerised MCC supply
  • Cable design
  • Electrical installation
  • Development of project commissioning plan
  • Development and management of permits isolation procedure
  • Commissioning of the plant
  • Production of O&M manuals

PROGRAMME

Design work and negotiation of the price was completed during 2018, with site installation and commissioning commencing in January 2019 and plant handover to Pacific Steel completed in August 2019.

Anglo Tasman offered an innovation to reduce the construction programme of the plant by using a containerised MCC – this innovation reduces the on-site civil construction required and allows the MCC building and MCC to be delivered as a single complete unit, therefore reducing site construction and offering enhanced quality with off-site MCC manufacturing and testing.

CHALLENGES

Due to the compressed programme, the mechanical design was still evolving as electrical installation progressed. To mitigate delays to the completion of the project we were able to rely on our relationships with other Auckland based electrical contractors to provide additional resources as the design changed.
