Specification of Atlantic Civil Products’ polymer-laminated ‘Trenchcoat’ Hel-Cor® corrugated steel pipe has resulted in substantial time and cost savings on the New Parallel Runway project at Brisbane Airport.
Brisbane Airport Corporation’s (BAC) New Parallel Runway (NPR) is an eight year project designed to upgrade facilities to meet predicted growth in flights in and out of Brisbane. It includes construction of a 3,300 metre long runway, more than 12 kilometres of taxiways, navigational aids, airfield infrastructure and hundreds of hectares of airfield landscaping.
BMD Constructions tendered for phase one of the civil works for the project, which included significant drainage works and required temporary tidal drainage lines to be constructed through surcharged sand, alongside an operational taxiway. BAC’s consulting engineers required these pipes to remain in place for between two and five years.
The project tender documents called for a HDPE dual walled, ribbed pipe. BMD was looking to establish cost saving alternatives for the project and proposed Atlantic Civil Product’s ‘Trenchcoat’ Hel-Cor® product instead.
Following a comprehensive due diligence process by the client, the alternative solution was accepted and three barrels of 1500mm diameter Trenchcoat Hel-Cor® corrugated steel pipe, each 198 metres long, were installed to AS2041-2010.
BMD’s Senior Pipe Foreman, Chris Pinnow, commented that the pipes, which were supplied in 12 metre lengths during March 2013, were light, strong and easy to install. This allowed BMD to lay up to 100 metres of pipe each day, despite having to deal with restrictive airport conditions.
