Project Context
Existing high-rise office building undergoing re-letting, tenant expansion, and conversion for multi-tenant use.
Summary
Approx. 3–4 months construction time per floor. RDA conversion approx. 8 months.

Project Scope

The works included the implementation of multi-tenant capability, including electricity, water, heat measurements, access, and doorbell systems. The foyer was renovated with a barista bar, employee showers, and a parcel station.

Additional measures included the construction of a daycare centre in the neighbouring building of approx. 900 m², the expansion of meeting and conference areas, and tenant extensions of approx. 960 m² per floor through zero/phantom planning.

The smoke pressure system was converted through the installation of three exhaust shafts across all 22 floors, each approx. 1 m². More powerful smoke extraction systems were also installed to support safe smoke extraction from the stairwells.

Project Requirements

The renovation took place during ongoing re-letting, which meant construction progress was directly dependent on the rental situation. Complex fire protection measures had to be integrated into the existing high-rise building.

The project required a high level of coordination with tenants, architects, and executing trades, especially where tenant requirements, technical upgrades, and leasing decisions affected the construction process.

Role and Responsibility

The role included project management on behalf of asset management, with management of the planning and execution teams. This included architects, building services engineering, and fire protection.

Responsibilities Included

  • Cost and schedule control
  • Budget management
  • Interface management between owner, tenant, specialist planner, and subcontractor
  • Contract management, including fit-out costs in rental agreements and special tenant requests

Project Outcome

The foyer, including ancillary rooms and showers, was completed, along with the daycare centre of approx. 900 m² and 7–9 rental floors. The new smoke pressure system was successfully commissioned, supporting the building’s conversion for multi-tenant use.
