Timber structure restoration · Australia

Restore the timber. Keep the story

We survey, repair, reinforce, and, only where we must, replace heavy timber structures and bridges, extending service life by decades while keeping as much original material as the structure safely allows.

An established Australian timber restoration operation

TRS has been operating in Australia since 2005. Our Queensland-based team, led by General Manager Patrick Bigg, a structural bridge and timber engineer, has completed timber restoration and construction projects for councils in New South Wales, Queensland, and Victoria.

Australia’s timber bridge network is one of the most extensive in the world, and a significant proportion of it is approaching or past its designed service life. Patrick Bigg’s engineering background gives TRS Australia the capacity to provide structural design, condition assessment, and project management under one roof, a significant advantage in complex council procurement environments.

Services for Australian clients

What TRS delivers for Australian projects

Australia holds one of the most extensive timber bridge networks in the world, council spans, heritage structures, and trail crossings, much of it aging and under local council responsibility, where thoughtful restoration and load-rating upgrades beat full replacement on both cost and disruption.

Council timber bridge restoration & upgrade

The majority of Australia’s aging timber bridge network sits under local council responsibility. We deliver Level II inspection, condition assessment, and upgrade/repair/replacement tailored to council budget cycles, procurement requirements, and asset management obligations.

Bridge load rating upgrades

We regularly upgrade Australian timber bridges to higher traffic loading standards, extending the useful life of existing infrastructure at a fraction of the cost of replacement.

Heritage timber structure restoration

We have worked with Queensland Heritage Register-listed structures, National Trust-listed buildings, and council-heritage structures, producing restoration specifications that satisfy heritage body requirements while meeting contemporary structural standards.

Pedestrian & trail bridge construction

As Australian councils invest in walking and cycling trail infrastructure, we deliver pre-assembled, ISO-accredited pedestrian bridges with documented 100-year design life, the quality assurance councils need for public infrastructure investments.

Timber bridge restoration across Australia

Completed South Arm Bridge alongside the adjacent span
Brunswick Heads, NSW · Oct 2020

South Arm Bridge

Client: Byron Shire Council

TRS upgraded this 63-metre timber bridge from 10-tonne to 44-tonne traffic loading. Existing timbers were recycled throughout the rehabilitation, treated with Copper Naphthenate Oil Emulsion and Anchorseal® paraffin sealant, with Decaystop® borate salt rods inhibiting fungi growth at treated cuts.

Completed Delegate River Bridge
Delegate, NSW · Sep 2020

Delegate River Bridge

Client: Snowy Monaro Regional Council

Based on a Level 2 inspection and condition report, TRS constructed a new sill beam foundation, fabricated two new frame bents, completed pile repairs, and replaced six corbels, sixteen girders, and a significant portion of the deck.

The TRS standard

The TRS difference for Australian projects

ISO 9001 certification

The only wood structure repair firm in the world with ISO 9001 certification. For council procurement officers and asset managers, that means a documented, auditable quality management system, reducing risk and providing the compliance documentation required for public infrastructure spending.

Queensland operations base

Our Deception Bay, QLD facility provides local project management, faster mobilisation, and an Australian team that understands the conditions, species, regulations, and procurement environment of Australian timber restoration work.

100-year design life, documented

We don’t claim longevity, we engineer it. Our ISO-accredited structures come with documented design life specifications that give councils and asset managers the data they need for long-term infrastructure planning.

EPHOD® inspection technology

Our proprietary electronic pulse diagnostic system detects internal decay in timber members before it’s visible, a critical tool for accurately assessing ageing Australian bridge stock and avoiding the cost of under-specified repairs.

For Australian projects

Specified to the standards your engineers already work to

Our Australian work is engineered to AS5100 bridge design (with SM1600 loading, or T44 where specified) and AS/NZS 1720 for timber, by RPEQ- and CPEng-qualified engineers, delivered for council procurement and state departments including TMR, DPI, and DAF, with cultural inductions and environmental permitting handled as standard.
