Multiplex Delivers $24M Riverview House in Melbourne

Construction of Fivex’s $24-million Riverview House commercial office building in Melbourne, Australia’s central business district has been delivered. The project team included general contractor Multiplex, architects Baldasso Cortese, with engineers Bonacci Group and IrwinConsult.

Located opposite Melbourne’s iconic Flinders Street Station, the second tower of Riverview House spans five levels delivering 4,000 square meters of lettable office space, and is connected to the existing tower lobby via a bridge link at each level.

The bridge link features an efficient truss design to alleviate the transfer of new loads onto the existing building. A weatherproof expansion joint has been installed between the bridge and the original building, allowing them to move independently.

Construction work commenced on Riverview House in March 2018 and during peak construction over 115 people worked onsite.

Riverview House was a technically complex project with innovative construction methods including the use of lightweight materials such as a modular structural steel grid and cross-laminated timber floor panels to limit the need to strengthen the existing structure below and enable compliance with engineering codes.

The location of the project, directly above occupied tenancies and adjacent to one of Australia’s busiest intersections, brought a unique set of logistical constraints and challenges. Structural steel-cantilevered protection decks allowed the new building to be encapsulated by scaffolding, providing overhead public protection and access for feature cladding.

The building is designed to 5 Star ecologically sustainable development with features including a new rainwater tank installed in an existing plant room to allow for rainwater harvesting technology.

276 Flinders Street is Fivex’s newly refurbished mixed-use retail precinct. The podium and ground levels comprise a fitness and childcare center and a range of retail and food stores, with extensive office space above.
