Located at 180 Thomas St in Haymarket, Built has completed a high-end three-level fitout for TransGrid which has earned the distinction of being the first fitout in NSW to achieve a 6 Star Green Star Office Interiors v1.1 rating in Round 1.

The client brief for the fitout was to obtain a 5 Star Green Star Office Interiors v1.1 rating. However, Built was able to identify an additional 13 weighted points to target, including 3 innovation points.

In addition to the TransGrid fitout, Built completed the base building works, undertaking a complicated mandate to deliver a nine-storey office building on top of an operational electricity substation which serves most of Sydney City. This construction activity took place during the continued operation of the substation. The base building also achieved its desired 5 Star Green Star As Built v3 rating in the Round 1 assessment and features a host of sustainable initiatives, including active chilled beam cooling, T5 zoned lighting and an HVAC system delivering 100% outside air. The highly efficient structural steel building has views out to Darling Harbour and
back to Central Park.

Joe Karten, Senior Project Engineer – Sustainability at Built said, “Through close collaboration with the client and design team, Built was able to redefine a pathway that surpassed TransGrid’s initial 5 Star requirement to reach for and obtain a 6 Star rating. In doing so, the project team helped gain recognition for the full extent of environmental initiatives delivered and continued Built’s proud tradition of building quality, sustainable workplaces.”

Design & Sustainability Features of TransGrid Fitout:

  • The use of recycled telegraph poles throughout provides functionally decorative secure walls and balustrading – and reduced reliance on virgin timber. It also celebrates TransGrid’s raison d’être: power transmission.
  • An inter-tenancy stairway cuts through the center of the floorplate opening up the floors to allow light to penetrate and connect staff across all floors.
  • Extensive specification of fitout furnishing and carpet with environmental product declarations – an Innovation Challenge awarded by Green Star.
  • Reduced finishes for circulation zones: polished concrete used on circulation paths and exposed ceiling services above these areas dematerialised the fitout.
  • Mixed mode Wintergarden with operable louvres, in-slab hydronic heating and hanging ivy.
  • An active chilled beam system provides energy efficient cooling for the building whilst conserving heating / cooling energy due to its thermal performance.
  • Office lighting is zoned to minimize lighting energy use after hours.
  • Facilities provide showers, lockers and change rooms to encourage cycling and walking
    to work.

Construction Activities:

  • A demolition and construction phase recycling rate of over 96% was achieved on site with less than 4% of material going to landfill.
  • Use of PVC alternatives or Best Environmental Practice PVC products was enforced on site.
  • Regular toolbox talks and subcontractor meetings around use of low environmental impact product ensured a healthy site.

Precision workmanship, exceptional collaboration and comprehensive problem solving – all part of the Built DNA – ensured an outstanding final product.
