Multiplex

What Multiplex does

Multiplex is a global construction contractor founded in Australia in 1962, delivering complex, large-scale building projects across ten sectors: office, residential, tourism and leisure, education and research, health and aged care, retail, industrial and infrastructure, data centres, defence, and justice/civic. The company has completed more than 1,150 projects with a cumulative value exceeding US$130 billion and currently operates across Australia (Perth, Sydney, Melbourne, Brisbane, Canberra, Adelaide), the UK (London regional HQ, established 1999), Canada (Toronto, established 2011), and the Middle East, employing approximately 2,500-2,600 people. Core technical capabilities include certified quality systems, BIM-based digital design and engineering, and mass timber construction methods, with dedicated workforces in healthcare live-environment construction, hyperscale data centres, and large public-private partnership social infrastructure.

Multiplex earns revenue primarily through fixed-price and cost-plus construction contracts tendered competitively, supplemented by construction management arrangements and public-private partnership structures for healthcare, education, and infrastructure projects. Pricing is bespoke, negotiated per project scope. Customers include government agencies, institutional developers, REITs, and large enterprise clients such as NextDC (data centres), the Victorian Government, Edith Cowan University, the Australian Government (Western Sydney Airport), Mitsui Fudosan UK, and the University of Glasgow. The company differentiates on brand heritage (Wembley Stadium, Stadium Australia, Burj Khalifa foundation), ESG credentials (first global contractor to sign the WGBC Net Zero Carbon Commitment), and surety of delivery enabled by Brookfield's capital backing. Current ownership is Brookfield Asset Management, with a definitive agreement in place for sale to Japan's Obayashi Corporation for $650 million, expected to close in Q4 2026.

Expansion highlights6 records

Broad incumbents

• Skanska: Swedish-headquartered global construction and development firm with broad sector exposure including commercial, healthcare, transport, and energy. Comparable in scale and international delivery model, but operates as a broader incumbent rather than specializing in Multiplex's niche sectors.
• AECOM: Global engineering and construction services firm delivering design, program management, and construction across transport, water, environment, and buildings. Comparable in scale and infrastructure exposure but offers broader professional services rather than pure-play building contractor model.

Regional players
