What Haslin Constructions does

Haslin Constructions is an Australian private civil construction company founded in 1991 and headquartered in Sutherland, NSW. The company delivers complex infrastructure projects for government clients across water and wastewater, energy substations, transport (rail stations, roads, bridges), heritage restoration, marine and coastal works, community and public spaces, and renewable energy (solar farms). Project values range from sub-$1M to $115M, delivered via Design and Construct (D&C), Early Contractor Involvement (ECI), Joint Venture, and Alliance contract models. The company has delivered over $1B in government infrastructure across its 30+ year history, including over $500M in regional NSW specifically.

The business is built on a sales-led, business-to-government (B2G) model where revenue is generated through competitive tendering and direct engagement with repeat government clients including Transport for NSW, Sydney Metro, Endeavour Energy, Ausgrid, Sydney Water, Queensland Rail, and numerous NSW and Queensland councils. Haslin's competitive position rests on extensive regulatory prequalifications (ISO 9001/14001/45001, OFSC, NSW Government WHS Edition 5, Transport for NSW F75/R4/B3, Health Infrastructure NSW, Sydney Water, Queensland Rail EEO), a 30+ year track record with sustained industry award recognition (CCF NSW/QLD Earth Awards, Engineers Australia, MBA NSW, IPWEA), and a heritage-sensitive delivery capability built through projects such as Sub Base Platypus, The Bakehouse Quarter, and Fort Denison.

Haslin operates from five offices across Australia (Sutherland/Sydney, Melbourne, Brisbane, Canberra, Adelaide) and is led by founder and Managing Director Colin Woods and General Manager Gladys Woods. The company runs structured talent programs (Intern Program of 4 graduates per year since the mid-2000s; Mentor Program of 36 participants debuted 2021) and partners with design firms (GANDEN) and specialist contractors (Stephen Edwards Constructions via HSEJV; Ultegra via UHJV) to access larger contracts. Strategic growth has been organic, funded by retained earnings, with no disclosed institutional investment or change of ownership since founding.
