Greater Wellington Regional Council approached HCP to make a precast platform and steps for better access to the top of the Birchville Dam, where Dam management and control takes place. There were weight restraints for the platform and steps because they would have to be helicoptered in. This project is an illustration of the complete design and build process HCP can do for customers. HCP designed and manufactured the platform and steps in three parts to meet the weight constraints, small location for installation and to fit alongside existing dam, which was on a radius. HCP had to take into consideration how the structure was to be put together after it was transported by the helicopter. The project went according to plan and the custom built platform and steps are well fitted on top of the Dam.
