Following end of warranty inspections undertaken on behalf of the strata committee significant issues were discovered that required major rectification.

55 Storey Premium Grade Office Tower – Fire Damper compliance upgrade

Bowsers was engaged by the property manager to undertake the compliance upgrade works of over 400 fire dampers in conjunction with the incumbent HVAC service provider.

Through scheduling enough trades personnel on day and night shift, the works were completed well in advance of the original project deadline, allowing for the building refurbishment and fitout to be completed well in advance of tenant expectations.

Service Penetrations and Fire Seals

Bowsers specialise in the protection of openings that penetrate fire rated elements.

Passive fire measures aim at containing or slowing the spread of fire through the use of elements such as fire resistant walls, floors and doors.  These elements are designed with a Fire Resistance Level (FRL).


Risk occurs when services such as pipes or cables are installed through fire rated elements without adequate protection. The FRL of the elements may therefore be compromised exposing the building to risk of spread of fire between fire compartments.


A range of systems have been developed by specialist manufacturers to seal such penetrations.  These systems are independently tested and certified for specific uses and site conditions.

Building compliance and certification is only valid when the choice of passive fire sealing system, its location and installation matches the tested prototype.


Bowsers’ management, supervisors and trades personnel are experienced in the installation of protective measures to ensure FRLs meet building design and BCA requirements.

Bowsers specialise in the installation and rectification of:

  • Fire Pillows
  • Fire Collars
  • Fire Rated Board Systems
