What nelmac does

Nelmac Pty Ltd is a family-owned Australian civil construction contractor founded in 1960 by Nelson McIntosh and headquartered in Albury, NSW, with a precast manufacturing yard and engineering division in Yackandandah, Victoria. The company provides integrated bridge and road construction services encompassing design and construction, pile driving, prestressed and precast concrete manufacturing, demolition, general engineering, and road and earthworks. Its core products include footbridges, deck slabs, void slabs, post-tensioned and prestressed structures, T Beams, T Roff (Super T) girders, PSC planks, precast concrete piles, and steel bridge components manufactured in-house. Technical differentiation rests on proprietary construction methods — notably a half-width construction process that maintains traffic flow on major routes, hot water curing of prestressed concrete at 70°C for early strength development, and temporary bridging for waterway pile driving to reduce environmental disturbance.

Nelmac generates revenue through competitive government tenders, primarily with Roads & Maritime Services (RMS), Vicroads, ACT Procurement, Transport and Main Roads Queensland, SA Road Services, and various NSW and Victorian shire councils. Individual project contracts range from approximately $1.5 million to $16.5 million, with the Fitzgerald Bridge replacement ($16.5M) and Lachlan River project ($9M) representing the largest disclosed wins. The company is federally prequalified at the highest levels — B3 Bridgeworks, R2 Roadworks, CC Precast Complex, and F25 Financial — and was the 300th organisation accredited under the Australian Government Building and Construction OHS Accreditation Scheme. Customer segments are entirely government (federal, state, and local), with project selection governed by tender processes and prequalification status. The business model is one-time contract-based, with multi-year contract cadence typical for major infrastructure projects. Revenue is not publicly disclosed, and Nelmac operates with no external funding, no parent company, and an undisclosed headcount, retaining private family ownership under the McIntosh family across two generations.

Product overview

Nelmac is a construction and piling company offering integrated bridge and civil engineering services.
