What Harrison Infrastructure Group does

Harrison Infrastructure Group (HIG) is a privately held, multidisciplinary engineering, design, and project management consultancy headquartered in Brisbane, Queensland, Australia, with regional offices in Toowoomba, Rockhampton, Bundaberg, Mooloolaba (Sunshine Coast), and Roma. The firm serves state and local government agencies — principally the Queensland Department of Transport and Main Roads (DTMR) and Queensland local councils — as well as private property developers and, more recently, renewable energy project owners. Its service portfolio spans civil engineering (road/highway and subdivision design), structural and bridge engineering, hydraulic engineering and stormwater management, transport/traffic/lighting and electrical engineering, project/contract/asset management, design visualisations, and industry training. Delivery relies on a team of over 90 technical and administrative personnel, including more than 15 Registered Professional Engineers of Queensland (RPEQ).

The company was originally founded in 1996 as The Harrison Group (QLD) in Brisbane and reached its current form in 2014 through a merger with sister company Highland Infrastructure Group. HIG operates a professional-services revenue model, billing engineering design, project/program management, and training services on a per-project basis (pricing is not publicly disclosed). It uses industry-standard design and modelling software including 12D, AutoCAD, Civil 3D, SIDRA Intersection, AIMSUN, TUFLOW, HECRAS, SpaceGass, and Structural Toolkit, and has developed in-house 12d model-based design tools and visualisation/3D-animation capabilities.

Go-to-market is relationship-led enterprise field sales anchored in public-sector procurement access: HIG holds DTMR prequalification across multiple categories (CM1.1, FC3, HE3, HD3, ITS2, TE3, TP2, CE1), is listed on multiple Local Buy panels, is an accredited service provider to Energy Queensland (Ergon and Energex) for street lighting, and maintains ISO 9001, ISO 14001, and ISO 45001 accreditation. The firm was the major contributor to the IPWEAQ-published Lower Order Road Design Guidelines (LORDG) and delivers associated training, and it has won the 12d Innovation Awards Design Category in 2021 and 2024 (Highly Commended 2018).
