The aim of this augmentation project has been to secure a more efficient gas supply for Semaphore residents for whom it has not been consistent. The work involved replacing 2 km of low pressure cast iron mains with 90 mm high pressure polyethylene pipes and installing a large district pressure regulator in order to regulate the redirected high pressure gas supply back down to an appropriate lower pressure.
Pass on my thanks and appreciation to the Diona and Metro Utilities teams involved in mains replacement work at Fulham Gardens
n accordance with APA procedures, and particularly the Concrete Cutting Prior to Excavation Flowchart process, the Metro Utilities crew made a decision to isolate gas supply prior to cutting concrete due to concerns over a possible shallow service within a Multi User site based on readings from the locator.

Following cutting and removal of the concrete multiple instances of shallow gas services were found within the unit site and the concut blade did actually contact the isolated gas service at Unit 6. The proactive actions of the crew to isolate gas supply prior to cutting the concrete prevented this becoming a Level 3 asset strike and exposing the workers to a hazardous situation. It also reinforces our belief that every asset strike is preventable.
