Please be advised of upcoming HVAC replacement works at 74 High St Toowong (490) scheduled from 22 April to 1 July 2024.

Works overview

This equipment is required to be replaced, with A.G. Coombs appointed as contractor for these works. The current project duration is between April 2024 and June 2024. Additionally, roofing repairs are scheduled to occur following the completion of the HVAC works.

Project details

A.G. Coombs will require to access the lower-level carpark, all floor levels and rooftop plant room spaces through the duration of physical works, currently scheduled between April 2024 and July 2024.

Works will commence with the scanning of floor slabs to determine exact locations for core holes. Following approval of locations, core holding will be undertaken before work hours across several days. Note that noise from these works should not be noticeable outside of the building.

During the works, a crane will be required to remove old and lift new equipment to the rooftop, which will necessitate the temporary closure of High St streetfront. This will be programmed to occur on a weekend and approval from Brisbane City Council will be required. Access to the ground floor plant room space will be via the lower-level carpark space and minor disruptions can be expected when this work occurs.

Final designs and shop drawings are being completed. The building is serviced from two plant spaces – one on the ground floor and the second on the roof of the building. The contractor will require access to these spaces to complete the proposed work. While works are being undertaken, there will be periodic disruptions to the air conditioning servicing the building.

During the works some equipment will be required to be operated in manual mode. As a result, some systems will be offline and temporary air-conditioning units will be positioned on affected occupied floors. Positioning of these will be coordinated with floor managers/representatives closer to the time.

A.G. Coombs will require access to individual floors periodically to install control equipment, service risers, and for balancing the system post installation. This may require the use of small tools causing occasional minor disruptions. Installation of the service riser will require core hole drilling which will be noisy; however, this core hole work will occur out of hours/on weekends to minimise disruptions.

Following completion of the HVAC works, a separate contractor, JMC Construction Solutions will commence roof repair/maintenance work to address known roof leaks. This work is anticipated to occur between July and August.

During the progress of the works, fortnightly lookahead schedules will be issued to keep building occupants and stakeholders informed of progress and future work activities. Stakeholder meetings will also be scheduled as required to address any particular concerns or issues.
