Scope of Work: Design and construct a Fire Rated encasement for a smoke extract exhaust and kitchen extract exhaust, together with a suitable supporting frame work that can support the weight of the Fire Rated Encasement.
Overview: All methods were based upon approved tested systems that have been test in accordance with Australian Standards. To achieve the scope of the works the Fire Rated encasement was constructed using Promat Promatech L500 together with Promat sealants and approved fixings. The L500 was used to encase and form the duct. It was also required to be Fire Rated from both directions. The structural steel supports were clad with Promat P50 to protect it, as they were inside the duct. This was a complex build with many logistic and build ability issues. The project last over 4 months using over 200 sheets of board.
