Long standing client Co Operative Bulk Handling Awarded Interlec WA Pty Ltd the Electrical Contract to complete all Electrical works on new Grain Receival Site Mirambeena. Mirambeena was a much needed addition to the Great Southern grain handling network, and the pressure was on to get the site ready for the bumper 2016 harvest.

The Mirambeena site is designed for an initial capacity of 140,000 tonnes made up of two 30,000 tonne open bulk heads and four 20,000 tonne cells, with provisions and plans to expand this number immensely.

Supporting infrastructure was inclusive of two 305m ground conveyors, four overhead High Roller Cross Conveyors, two 36m high  80 tonne per hour grain bucket wheel elevators, six discharge augers, two portable conveyors and a state of the art sampling hut incorporating a Tekpro engineered computerised sampling system.

Client – Co Operative Bulk Handling

Location – 15km north of Albany, Industrial Estate Mirambeena, Down Road, Drome.

Scope of Work

Supply and Installation of all Power, Control and Instrumentation Cabling and Installation of Plant Instrumentation and associated cable support systems. Interlec was responsible for the supply and Installation of the Site Main Switchboard, two Main Control Centres, Multiple Distribution Boards and Control Cubicles including motor management and Programmed Logic Control systems and supply and installation of all power and communication distribution networks.

Interlec relied on their switchboard division to construct one 800amp Site main switchboard, Four Motor Control Centres and 5 stainless steel weatherproof industrial heavy duty distribution boards. All motor control centres incorporated extensive heavy duty bus bar arrangements, plc control and multiple soft starters and motor management facilities.

Interlec Civil division Excavated approximately 1256m of trenching, utilizing various in house Excavators and Trenching plant, logistics was full time running all plant between Perth Head office and the work site in Albany.

The site consisted of an extensive underground power and communication distribution network, inclusive of a fundamental fibre optic and communications cabling, this was essential to getting all onsite information back to Perth, and for all control systems to work with each other, this system was the life line both on site and for remote access. High speed data transfer was invaluable to produce reliability and efficiency, as well as provide information to the local farmers and growers.

High energy requirement site wide meant kilometres of heavy duty XLPE cables were installed for power distribution purposes. The weather was against the onsite crew, meaning all trenching had to be approved prior to commencing, as too much water in the ground would cause trench failures and in-turn road failures. Interlec on site supervision worked alongside fellow contractors and CBH construction supervisors, to insure all civil works were compliant and completed within the tightly set timeframes allocated to beat the weather.

Interlec installed approximately 5890m of cabling with zero insulation resistance failures or high fibre resistance readings.

On site the weather proved challenging, during the course of total construction there were 219 recorded rain days totalling 1,114.5mm or rain fall, high winds and storms. Interlec’s ISO 9001 accredited safety management system proved affective yet again, Interlec were on site 158 days and recorded zero lost time injuries.

Interlec again would like to thank Co Operative bulk handling for their support and assistance throughout the project, enabling a safe and efficient process of construction.

Thanks must also go to the sub-contractors onsite:

  • Cardinal Contractors
  • Perth Rigging
  • Dencona Pty Ltd

Extensive wet weather placed high demands and pressures to meet budgets and deadlines requiring  the Interlec crew to pull together to ensure this job was completed successfully and safely and on time.

Years of experience and knowledge cannot be beaten, and Mirambeena is another success to the Interlec Profile.
