KAPP has recently successfully commissioning a turnkey control system incorporating a PLC based control system to open and close the maintenance roof at the Perth Mint. KAPP was contacted originally by architects Hindley to provide a turnkey system for builders Northerly who were constructing the Perth Mint expansion. A turnkey system incorporating electrical design, panel fabrication, control system programming, electrical installation and commissioning works was provided. KAPP has worked on numerous similar retractable roof projects with clients Vector Lifting and were able to complete the design and install successfully.
