Cape was responsible for the installation of the high pressure gas pipeline which will ultimately connect the Dampier to Bunbury Natural Gas Pipeline with the Rockingham and Mandurah areas in Western Australia. With a rapidly expanding population in the City of Mandurah there was an increased demand on the dwindling gas supply. The Shire of Murray will also benefit from the new pipeline with its ever increasing population expected to triple by 2021. The Mandurah Gas Lateral will provide security of supply to these booming areas.

Cape utilised a combination of Horizontal Directional Drilling, traditional trenching and excavating methods. The pipeline involved approximately 20km in total, passing through the Serpentine River, smaller creeks and a number of environmentally sensitive areas. Minimising the impact on the environment was of vital importance and the planning ensured this outcome was achieved. In addition to obtaining a licence to construct, an Environmental Management Plan was carried out and approved prior to the commencement of the work. There were a number of environmentally sensitive areas identified which contain protected flora and fauna, which included 200 species of native plants in the area, 20 species of native animals of which 3 are classified as threatened species. A Land Liaison Officer on site was also appointed, as the pipeline travels through a number of farming properties and new residential suburbs. Cape liased with Aboriginal Monitors and Elders to ensure the integrity of Aboriginal Heritage within the area for the duration of the project.
