Outcomes

BMD Constructions worked closely with stakeholders. to build a new helicopter sloped training facility on the base. The project team also developed a strategy to manage the risk associated with water runoff on unsealed/exposed soil and/or gravel. The approach was a combination of erosion and sediment controls, staging of the works to minimise exposure, and covering of exposed materials with clean imported fill or other waterproof stabilisers. An initiative was adopted to utilise precast airfield class stormwater pits, which reduced the duration of open trench excavation, and accelerated stormwater installation.
