Years of combined construction expertise and experience
Our executive management team brings more than a century and a half of hands-on delivery leadership to every programme we undertake.
Marco Fabrizio
Chief Executive Officer
Spending the bulk of his career inside the problems we're trying to solve he's seen billions of dollars of disputes and value leakage across construction. Building contracting businesses sitting across developers, subcontractors, financiers and government. Seeing the depth of how much margin disappears because the structural package is fragmented across counterparties his vision and expertise is a cornerstone.
Brendan Lloyd
Chief Operating Officer
Oversees day-to-day group operations, project delivery execution and integration across the acquired businesses. Runs the operational rhythms that tie safety, procurement, concrete, steel, ground engineering and labour into a single coordinated delivery machine. Builds accountable, high-performance teams and a culture where safety, ownership and delivery discipline run through every project.
Oscar Ledlin
Co Founder
Licensed commercial builder and concreter by trade, and founder of Ledlin Group. Has developed and delivered more than 100 industrial units across Melbourne, building a reputation for solving sites other developers walked away from. He pioneered the Flexie concept, a boutique warehouse and business park format aimed at owner-operators priced out of traditional industrial stock.
