our Scope

Willis Bond engaged Marshall Day Acoustics to deliver the base build acoustic design services for the eight-level development. Tauranga City Council engaged Marshall Day Acoustics to deliver their fitout.
Our scope included managing external noise ingress, internal sound insulation, reverberation control, and mechanical services noise.
The building was designed to achieve the highest sustainability benchmarks, successfully attaining a Green Star 6 rating. Acoustic design played a key role in this achievement, with the project targeting and securing all three available points under the Green Star acoustic criteria. Additionally, we conducted an assessment against the WELL Building Standard, ensuring the acoustic environment contributes positively to occupant health and wellbeing.

CHALLENGES

The project presented unique acoustic challenges due to the exposed CLT structure, requiring innovative solutions to meet high-performance standards while maintaining cost-efficiency and buildability. A raised acoustic floor is not common in New Zealand office fitouts and adds complexity when considering the staging of basebuild and fitout activities.
We worked with the design team to develop a novel way to ensure fitout walls were constructed off the CLT structure but ensured that the raised floor could be installed early in the programme.
