900 employees across seven locations have been united at the new DEWNR 10,000sqm headquarters at 81 Waymouth Street, Adelaide.

The Department of Environment, Water and Natural Resources (DEWNR) engaged with Schiavello, MPH, Aurecon, dSquared Consulting and Aquenta to consolidate 900 employees from seven offices into the 35-year old dormant ATO building at Waymouth Street.

The project's scope aimed to develop and implement a change management plan for the 900 government workers, refurbish the dormant building, and transform it into an energy efficient, green building of the future.

Schiavello’s Early Contractor Engagement (ECE) with DEWNR allowed the team to establish a comprehensive and cost-effective methodology for targeting the 6 star Green Star Rating, whilst transforming the 35-year old ATO building into the green building of the future.

Careful control over the design, change and other project specific consultants ensured Schiavello were able to integrate the Base Building upgrade with the Design & Construct fit-out works, optimising the programme and ensuring the asset owner’s and end user’s briefs were met simultaneously with cost efficiencies wherever possible.

DEWNR not only highlights Schiavello’s expertise in sustainable design and building life cycles but also demonstrates competency in delivering complex projects.
