intercontinental hotel, sydney

description of project
The 35-storey building, built in 1982 required the 529 hotel rooms, front-of-house lobbies, the rooftop bar and restaurant and various back of house areas to be refurbished. The client also wanted to replace the existing HVAC systems in each of the hotel rooms, which could operate issue-free for the next 25 years.
The project requires for us to replace the existing HVAC systems in each of the hotel rooms and major plant upgrades. Our initial dilapidation report found the risers supplying chilled and hot water to the rooms were rusted and required replacement. From here we received approval to develop designs to replace 8 existing risers with a single central core located riser and ring main on each quest room level.
Following the initial design, the PJS Air team are permanently onsite for 18 months during the ECI process to ensure the project will be completed on time and to budget. Through the ECI process, the team is gaining a deep understanding of the overall building in order to create a system design which will guarantee operational efficiency and longevity.
