To reduce the developments upfront carbon, BG&E designed ancillary offices using mass timber.

The proposed development comprises the construction, fit out and operation of a two-storey warehouse and distribution centre with ancillary offices, which includes:

• Demolition of all existing structures and buildings on site.
• Retention of existing fire tanks and pump room.
• 24,485m2 of total gross floor area (GFA) comprising approximately:

• • 19,864m2 of warehouse GFA across eight warehouse units
  • 2,790m2 of office GFA, and
  • 773 m2 of rooftop garden area.

The office structure comprises:

• One level of concrete mezzanine floor.
• Two levels of timber office floor with Glulam timber columns and beams and CLT floor panels.
• One level of timber rooftop terrace floor with Glulam timber columns and beams and CLT floor panels.

BG&E SCOPE

• Structural design for the timber office building attached to the main warehouse core – from concept design to 70% tender detailed design.
• Provide specialty timber services, including acoustics advice for timber floor and fire design of timber elements.
• Auto-extinguishment analysis of timber structure.
• Provide high level costing plan.
• Undertake embodied carbon calculation of office structure with different construction methodology.

KEY TECHNICAL ACHIEVEMENTS & INNOVATIONS

• Provided structural design options to keep timber procurement options open.
• Provided auto-extinguishment analysis of timber office structure to prove each compartment fire will put itself out within the specified FRL.
• Lowered the embodied carbon of the development by utilising exposed timber for the office structure.
