CivilPlus were engaged by AMSA to assist with upgrading the maritime safety asset at High Peak Islet, approx. 100Nm to East of Mackay in North Queensland. ASMA operates a network of marine Aids to Navigation (AtoN's) with the purpose of these AtoN's being to assist vessels to safely navigate Australian Waters. The structure conisted of a 3m tall concrete blockhouse and concrete helipad. The concrete blockhouse was showing signs of reinforcement corrosion which had led to spalling of the concrete cover and cracking. A number of areas on the perimeter of the external roof had significantly deteriorated resulting in sections of concrete falling from the strucutre. The helipad had some large cracks, and uneven landing surface and significant drop offs on most sides with no safety nets. CivilPlus task was to demolish the existing concrete blockhouse and install a single module hex tower and new stainless steel/fibreglass helipad.
