Westmead Children's Hospital - Fire Rated Walkway
When Westmead Children's Hospital upgraded their facilities, new covered steel walkways were also constructed, allowing access between buildings without the need to go outside. John Holland Constructions, the appointed site superintendents realised the need to fire rate the load bearing steelwork, understanding that protecting the structural strength in case of fire was imperative to the longevity and safety of the steel structure.
Not having the specialized staff to be able to do it themselves, they contacted our offices with the view to having us prepare and spray the steelwork to a fire rating of 120 minutes. Part of the brief they gave us was that they wanted to achieve an aesthetically pleasing finish with exposed steel beams. The choice from there was simple - Thin Film Intumescents. The solution was chosen not only for its aesthetic appeal but also for its ease of application and sound fire rating efficacy.
Once on-site, Remedial Building Services erected an encapsulating structure to prevent overspray and then began the process of treating the existing coatings with a compatible primer. Once complete our fully independently qualified team applied the thin film intumescent to the desired thickness to achieve the 120 minute rating. A pigmented two component polyurethane was then applied as a sealer coat. All firerating works were carried out during normal work hours with minimal disruptions to other trades.
