Macedon Gas Plant

The Macedon domestic gas facility commercialises natural gas from an offshore lease located in the Exmouth Sub-Basin. Gas from the plant is exported to the Dampier-to-Bunbury Natural Gas Pipeline for sale into the Western Australian market.

ONSHORE FACILITIES CONTRACT

BGC Contracting was involved in the development of the on-shore facilities being constructed 16km south-west of Onslow in Western Australia. The initial contract saw BGC complete the construction of a 13km access road to site, including the installation of signage’s, road marking, storm water drainage, single seal for the 13km, and asphalt in the intersections. During the final months of this project, the BGC team worked closely with the client to construct the access road in half widths. This allowed traffic bringing the gas plant equipment to continue undisturbed. BGC was able to achieve all the key completion dates in time without any delay.

BULK EARTHWORKS CONTRACT

In September 2011, BGC began working on the site preparation after securing a second contract for bulk earthworks. The site preparation works included the construction of two evaporation ponds, stormwater pond, ground flare, concrete ditches, fencing and gates. A total of 50 variations were added to the initial contract, increasing the contract value by $20 million.

The repeat business aspect of this project stands testament to BGC’s commitment to maintaining strong and mutually beneficial relationships with its clients.

CONCRETE PLANT AND FOUNDATIONS CONTRACT

Two months after the site preparation work commenced, BHP Billiton Petroleum contracted BGC to establish a mobile ready mix concrete plant under a third contract, as well as construct concrete foundations and ground pavements for the Macedon Gas Plant (both insitu and precast). All underground services such as storm water drainage, fire water service, potable water reticulation and electrical earthing was completed for the concrete plant.

Key parts of the third contract were handed over early to allow the structural mechanical and piping contractor to start work early on critical foundations. BGC were required to meet seven key dates, all of which BGC achieved in time.

The repeat business aspect of this project stands testament to BGC’s commitment to maintaining strong and mutually beneficial relationships with its clients. The combined project value for these contracts was in the region of $110 million.
