Spiire was engaged to provide Civil Engineering, Landscape Architecture and Water Engineering services for Capital Estate Developments at Canberra’s growing Denman Prospect community.
The new suburb is a significant addition to the Molonglo Valley district, including a village shopping centre and a mix of freestanding houses, townhouses and apartments.
Our team provided construction management services for the 10ha Denman 1B Stage 2C site, comprising six multi-unit and 42 residential blocks.
Several pre-existing geotechnical conditions were identified during the construction process. Sections of unsuitable material were remediated across the site and our team managed challenging ground conditions such as shallow high-strength rock and isolated groundwater.
We worked closely with Capital Estate Developments and the multi-unit site purchasers to ensure the construction works were delivered according to the architectural designs. This stage required the construction of approximately 200m of trunk sewer, which involved careful consultation with Icon Water due to the connection to the Molonglo corridor’s trunk sewer.
Our Landscape Architects provided the landscape design for stage 2C, showcasing the estate through the use of detailed landscape elements involving planting beds and street trees.
The team is also providing Landscape Architecture, Civil Engineering and Construction services for the first three stages of Denman North, which encompasses 69.3ha of former pine plantation and forms the western edge of the Molonglo development corridor.
The estate and its unique open space include several opportunities for placemaking, such as the provision of heritage trail nodes, garden rooms and viewing platforms that capture extensive vistas back to central Canberra and the surrounding hills.
This aspect of the project has involved extensive coordination to prepare the Estate Development Plan submission and Heritage Trail Masterplan. Our team has developed solutions to interfaces between the open space and buffer zones, conservation areas and sites with geological or heritage values.
Working closely across disciplines and with key stakeholders, we have navigated challenges including steep slopes, multiple zones for water supply, surplus materials and tight timeframes to meet settlement dates.
