Case Study: 28 Barrani St, Bentleigh East

Project: 28 Barrani St, Bentleigh East
Client: Private
Contract Type: New Homes Contract HC6 – Turn Key solution
Project Type: Side by side development.

The project was traditionally designed for conventional construction then integrated with the Impresa House offsite manufacturing (OSM) solution. The dwellings footprint had staggered articulation and incorporated multiple façade options (brick, render, timber and steel). Roof also featured an architectural design, that included flat, trussed and a cathedral ceiling detail.

Time: Manufacturing was completed over a 12-day period.
Wall Panels: 38 external GF walls, 30 internal GF walls, 30 external FF walls and 36 internal FF walls. OSB was fixed to both sides of the timber frame and plaster was also fixed to panels before arriving on site.
Cassettes: 38 GF cassettes, 10 FF roof cassettes – the remainder utilised a truss system. The ground floor and first floor were insulated with an XPS and FC sheeting solution – this reduced vibrational transfer, provides thermal and acoustic insulation and improves structural integrity of the dwellings.
Parapets: 22 PW. Majority of the parapets were manufactured in factory.
Windows: Windows were supplied from a local sub-contractor and were partially installed in the factory and the rest were installed and glazed on site.

Time: Construction of the Impresa House shell was completed over a 22-day period.
Logistics: A 40ft semi-trailer truck reversed onto the block for unloading – walls were loaded onto A-frames and cassettes were flat packed.
Crane: 13 operational crane days were required to install all panels and cassettes. A 55 tonne extendable boom crane was used. A spotter was also required for crane operations as power lines were a factor.
Slab: Traditional raft slab solution was constructed for the slab. Variances in slab levels ranged between plus-minus 8mm, hence packers and a self-leveling grout was utilised for installation of finished panels to control heights.
Finish: A high-end level finish was highlighted in this project. Miele appliances, engineered oak floor boards, floor to ceiling tiles in wet areas, frameless glass showers, independent split system units in each room, stone bench tops and marble splash-backs, double glazed aluminum windows, and multiple outdoor areas with attention to detail throughout the entire project.

 “ As the first project completed using our Impresa House Solution, it was great to see resounding positive feedback from our employees, industry participants, general public, the developer and most importantly the end user. It was a great success and an exciting first step for Impresa House.” - Sean Morley – CEO
