The work is the proof

Timber Restoration Services (TRS) won the contract to upgrade the 63m bridge from 10-tonne to 44-tonne traffic loading. As part of the rehabilitation process, TRS recycles the existing timbers where possible and reuses the log timbers at the Council stockyard.

To ensure the recycled timber receives the best protection, TRS applies Copper Naphthenate Oil Emulsion (CN oil) and uses a paraffin-based sealant, Anchorseal®, to seal the cuts. The cuts are treated with Decaystop®, borate salt rods, to inhibit fungi growth and maintain easy access to the bridge elements.

TRS entered into a contract with Snowey Monsaro Council in June of 2020, to carry out repair upgrades to the Delegate River Bridge. The upgraded design is based on a Level 2 inspection and condition report that was carried out in 2018.

The work done on the bridge was comprised of constructing a new sill beam foundation, as well as the fabrication of two new frame bents. Our certified timber technicians also completed pile repairs, and the replacement of six corbels, as well as sixteen girders. A significant portion of the deck was renewed as well.

Timber Restoration Services (TRS) was awarded the contract to produce a design/build bridge to replace the existing 48-year-old steel arch bridge just outside of Amherst, NS. Located in the highest embedded and exposed corrosion zone in Canada, many elements of the bridge were rusted out and failed. The bridge was taken out of service and slated for replacement in 2017. TRS contracted Wood Research and Development (WRD), to design a unique state-of-the-art timber bridge. Due to the uniqueness of this bridge, WRD was also responsible for construction oversight for the project. WRD's first step in the design work for this project was to test the existing 80-year-old timber piles used in the old bridge.

TRS manufactured the bridge in our state-of-the-art plant in Jefferson, Oregon with the aid of several Canadian technicians who spent three months in Jefferson to aid in the construction of this bridge. The bridge components were shipped to the project site in 25 tractor-trailer loads. The structure consists of two 12-meter jump spans and a 39-meter three-pinned glulam timber arch. The design included the placement of the arch span using a 500-tonne crane, sitting on one of the jump spans, with a smaller crane on the opposite jump span helping guide the arch in place.

Timber Restoration Systems has this week commenced work on Sugarloaf Road Bridge in Axedale, Central Victoria.

Work includes replacing log girders, driving new piles, repairing old piles, and installing a new transverse deck. The bridge will be closed for the period of the works.

This glulam all-timber bridge is 21.2m long, spans 20.6m an has a 5.5m deck. The bridge sits on a 2 percent grade and has a 20-degree skew.

This resource road bridge is designed for an L100 loading and comprises five Douglas Fir glulam girders reinforced with aramid fibers for shear and bending. These are overlain by a glulam subdeck and solid running planks.

This bridge was designed, fabricated/preassembled off-site and reassembled on-site, as a demonstration of what is possible for timber bridges in British Columbia.

Snowy Valley Regional Council recognised the growing trend and applied for NSW Government's Restart NSW Regional Tourism Infrastructure fund and Stronger Communities grants. Through this funding, the 21km Tumbarumba to Rosewood Rail Trail, a walking and cycling trail that runs through a non-operational railway corridor, became the pilot for the State and a working model for future New South Wales rail trails.

Jimmy Gully Pedestrian Bridge crosses Jimmy Gully along the Brisbane Valley Rail Trail (BVRT) near Harlin, Queensland. Jimmy Gully Bridge was a 6 span timber railway bridge that was decommissioned in the early 1990's. Each span consisted of three girder lines with the two middle spans comprised of double stacked hardwood log girders. Each pile bent has three hardwood timber piles with the middle two bents consisting of five piles with the outer (batter) pile on each side providing lateral stability to the structure.

An extensive inspection of Jimmy Gully Bridge was completed by Wood Research and Development (WRD) technicians on 24 May 2016. The aim of the inspection was to complete the visual and decay detection testing analysis of the in-situ condition of the major structural elements of the bridge. The design of any restoration refurbishment, upgrade and repair strategies was then taken into account based on the inspection data collected.

A high-priority project in the Wiradjuri Trail Master Plan. TRS delivered a pre-machined, pre-assembled engineered glulam footbridge with a 100-year design life and near-zero maintenance, ISO 9001 accredited, with an angled handrail that keeps cyclists clear of the balustrade and a hardwood top rail softening the structure into the bushland setting.

A 75.3 m former Canadian Pacific Railway bridge, last used in 1985 and now a popular river-and-falls lookout. TRS replaced the caps, superstructure, deck, and railings on the existing piles, bringing the crossing up to current code while keeping its heritage character.

A recreational building shaped like a bird's nest, where extended rafter and beam ends had been weather-damaged. TRS sourced matching glulam from the Southeastern US, machined replacement lengths in the shop, and used mortise-and-tenon connections for a repair that is structurally sound and invisible from the outside.

After a newly renovated men's lounge, inspection revealed the roof truss system and supporting members were failing. TRS restored the full roof structure, preventing roughly $1,000,000 in replacement costs and preserving the renovated interior below.

A 2,212-seat multi-purpose arena and long-standing home of local hockey and figure skating. TRS restored the arena's timber arches and preserved them against decay, securing the much-loved structure for decades of continued use.

The tallest surviving intact four-legged timber fire tower, built in 1964 from four 30 m grey ironbark poles and Queensland Heritage-listed in 2018. TRS repaired the columns and cross-bracing, added anchor blocks and guy wires to reduce deflection, and made the lookout cabin watertight again.

After a Level II inspection by Wood Research and Development found delaminated upper glulam rafters, a two-technician TRS crew installed Retroshear® shear panels to strengthen the girder elements, restoring the roof system's capacity and adding many years of life cost-efficiently.

An 1897 timber bell tower, National Trust-listed and the last building of its nineteenth-century complex. Working with Heritage Queensland, Wood Research and Development designed an exact replica replacement that mimics every original element and validates capacity under cyclonic wind loading, so the tower can stand another 100 years.
