Three TAS road contracts: network maintenance and staging notes for engineers
Reviewed by Tom Sullivan
First reported on Roads & Infrastructure (AU)
30 Second Briefing
Three regional contracts have been let for spring road maintenance, resurfacing and repair across Tasmania, covering 84 sites on the state network. Victorian surfacing specialist Roadways will deliver asphalt and spray seal works in the north-west and southern regions, while Hazell Bros will manage civil and pavement works in the north. The programme signals a concentrated seasonal push on surface condition, drainage and structural repairs, with implications for traffic management planning and quarry/asphalt plant scheduling across multiple districts.
Technical Brief
- Spring scheduling allows resurfacing to be programmed around Tasmanian freeze–thaw and rainfall cycles.
- Separation of north, north-west and south into three contracts enables region-specific pavement and drainage detailing.
- Roadways’ surfacing focus suggests predominance of thin asphalt overlays and spray seals rather than full-depth reconstruction.
- Hazell Bros’ civil scope in the north likely includes subgrade improvement, shoulder widening and culvert upgrades.
- Multiple quarries and mobile asphalt/spray-seal crews will need coordinated shift rostering to cover dispersed locations.
- Contract packaging by region reduces haul distances for aggregates and binders, limiting temperature loss in asphalt delivery.
- Similar seasonal maintenance bundles in other states typically compress design review, workzone safety audits and stakeholder approvals.
Our Take
Roadways’ recent work on the Southsea Coastal Scheme in Portsmouth and a National Highways scheme, both outside Australia, suggests the Tasmanian contracts are being awarded to a contractor with current experience delivering to UK highway and coastal standards, which may influence specification choices and QA expectations in Tasmania’s north, north-west and southern regions.
With 84 sites scheduled for work this spring, the programme scale is closer to a network-wide maintenance package than a single-corridor upgrade, implying significant traffic management and staging complexity for Hazell Bros and Roadways across dispersed Tasmanian locations.
