HEALTH & SAFETY
How to ensure and safe demo In the demolition industry safety is the main concern as demolition is very complicated and involves high risk in terms of safety and cost. A minute deviation with respect to the timing of successive detonators, placement of detonators, and miscommunication can cause the demolition process to fail. Industrial Buyer caught up with Jet Demolition contracts manager Kate Bester to breakdown what safety measures are taken in demolitions and implosions projects.

transport allowances. These items often amount to a significant portion of the cost of work and must be adequately planned for. Another vital consideration on largescale demolition projects relates to the treatment and handling of inert waste. Depending on where the project is located, suitable spoil facilities may not be available, and crushing may be needed to revert concrete rubble to a viable construction material. Irrespective of the end-use of the material, there is always a significant proportion of cost allocated to waste – albeit in the form of disposal costs, crushing costs, transport costs, or re-use in rehabilitation.

Kate Bester: One of the most common oversights on large-scale projects is determining up-front who takes liability for security of the site. The South African construction industry is facing everincreasing work disruptions, which in turn puts plant and personnel at risk. A large-scale demolition project typically follows a mechanical approach, resulting in multiple large machines and attachments being present throughout the duration of the works. It is imperative to have a full-time, on-site security presence, in order to maintain the rule of law. The contractor and client must also ensure that the security personnel deployed to a project are adequately trained and have all requisite certifications in place.

What are some of the challenges of implosions?
Implosions aren’t necessarily any more or less complicated than any other demolition project. The methods used in implosion execution are heavily dependent on a very high level of skill and precision planning, as are the vast majority of other more conventional demolition methods and types. It is important to remember that demolition depends, on the most part, on gravity. Understanding a structure, it’s
