These works were conducted at the Australian Marine Complex Common user facility at Henderson WA. The challenge was to meet the strict Environmental requirements of the AMC and to not impact on neighbouring projects at a very busy tile at the AMC CUF. TBH met this by Fully scaffolding and encapsulating coupled with a mobile extraction system and continuous cleaning using our own vacuum trucks The Project was a complete success with a high quality end product delivered on Time and budget and no impact on other CUF users or the environment.
