61 Mary Street, Brisbane

Base building upgrade and integrated fit-out works across 18 floors

Buildcorp was engaged by QIC for the design and construction of the base building upgrade at 61 Mary Street. The scope additionally included the design, documentation and refurbishment of existing amenities and lift lobbies, plus the installation of new PWD facilities within tenancies and common areas.

Each of the four separable portions included the demolition and reinstatement of the existing office fit-outs on all 18 floors. The new fit-outs include upgrades to existing mechanical and electrical services, new hydraulic services, fixtures and fittings, carpets and ceilings. Along with the refurbishment of the existing amenities and lift lobbies, upgrades were also made to the chilled water lines, condenser lines, fire services, mechanical plant and external balconies.

Careful coordination
Works were undertaken whilst the building was occupied by numerous government agencies, so careful consideration was required in planning and communicating with key stakeholders. Refurbishment works were managed floor by floor which required tenants to move out and back in. Initially, there were seven empty floors however when the works were completed the occupancy had increased, along with the tenant movement and public interfaces. To minimise disruptions, noisy works were done out of hours and the goods lifts were used to move materials.

Buildcorp’s program included a contingency for any undocumented cabling and services, and these were detected early, allowing early handover for some of the floors.
