Marine demolition FAQs

What assessments need to be performed for marine demolitions?

Marine demolition work involves aspects such as deconstruction, wrecking and dismantling marine infrastructure. As such, pre-demolition planning and risk assessment are critical to ensure safe, controlled and effective marine demolitions are achieved. These assessments are often performed by demolition consultants or demolition engineers, in conjunction with input from project stakeholders.

Pre-demolition planning involves strategically inspecting and analysing the prospective site or structure and devising the most effective, safe and efficient method of demolition according to the specific site’s features.

Risk assessments identify potential hazards and risks to people, other structures and the environment. They detail risks inherent in demolition work and also the unique factors present at any particular site. In marine demolition it is important for assessments to comply with environmental regulations, such as the Environment Protection Act.

How much does a marine demolition project cost?

Every marine demolition project is different in terms of its size and difficulty. There isn’t an easy way to assess the price of a marine demolition project without having a demolition expert review the project first. At the Major Projects Group, we streamline this process when you contact us for a quote.
