Kurow_Bridges_01

Kurow Bridge Replacements, Waitaki

Work on new bridges to replace the 132 year-old two single lane bridges (256m and 140m long) across the Waitaki River on SH82 at Kurow started in March 2013. The first of new bridges on the Kurow side of the river opened in April 2014 followed in early June, by the second new bridge on the Hakataramea side of the river. The entire project including the removal of the old bridges, is expected to be completed in late 2014.

These bridges will greatly improve route security along SH82 between Kurow and Waimate and protect a vital link between Kurow and the Hakataramea Valley, which has existed since the current bridges opened in 1881.

Trusted Weka SG8 and Weka No.1 products were supplied through one of our Approved Resellers in Oamaru and Timaru working with the main contractor Downer.

Not only does the replacement bridges enable local people to walk or cycle safely between the two communities but it also supports the tourism industry by providing a safe passageway for cyclists who want to visit the Waitaki Valley and stay a little longer to enjoy its hospitality.

Two spans from the old timber bridges will be permanently displayed on Kurow Island to preserve part of the area’s history

Hyde_Bridge_02

Hyde Bridge Restoration

One of the oldest bridges in the wider Dunedin area, and the main link between Hyde and Macraes, the Hyde Bridge has undergone extensive repair work.

The $407,000 project, including the replacement of the bridge’s deck while the contractors are there was a 3 month project and undertaken by Alexandra based Breen Construction.

Our Timber Consultants worked closely with the civil engineer, Breen Construction and our local Approved Reseller to come up with a unique solution to a difficult project. Trusted Weka SG8 timber was used to baulks as the picture shows – laid on edge and bolted together, to achieve maximum strength and stiffness for this vehicle bridge.

The bridge over the Taieri River on the Hyde-Macraes Road was built in 1879. The bridge was constructed as the result of community agitation; the Taieri River could be dangerous in flood, and the upper Taieri area was isolated. The bridge provided safe crossing and a stable connection with the outside communities. The bridge is a testament to the design and work of the County Engineer Robert Browne. The bridge has an iron lattice truss for the main span and short timber arch trusses at either end. The piers and abutments are stone. It was adapted to the site by the addition of a 30 ft (9.1m) span at each end, to give a total length of 160ft (48.7m). The deck is 30 ft (9.1m) above water level, and it has a load limit of 609 tonnes. The bridge remains a notable landmark on the Strath Taieri.

Clifden Suspension Bridge Restoration

Clifden Suspension Bridge Restoration

The Clifden Suspension bridge spans 111.5 metres over the Waiau River, and is the longest suspension bridge in New Zealand.

Settlers depended on a ferry to get stock and supplies across this dangerous river. By the early 1890s the Government funded a punt attached to a wire rope until the bridge was built in 1898-99 taking ten months to complete. It was opened on 5 April 1899 by Sir Joseph Ward.

Southland County Engineer C H Howorth designed the bridge anchoring the cables into limestone deposits. The tapering towers are 7.5 metres high, the steel cables weigh 28 tonnes and the decking and beams are made from heart totara. The bridge is 3.5 metres wide, and acted as a single lane bridge for horse-drawn traffic although traction engines were soon towing lime and wool over it. Trucks and cars traversed it from the 1920s and it remained in use until 1978 when the current bridge was opened downstream.

This is a category 1 Historic Place – New Zealand Historic Places Trust.

Extensive repair work was undertaken and it was reopened in November 2013 after being closed in 2010 due to its deterioration. The work undertaken by Fulton Hogan and managed by OPUS International on behalf of NZHPT included replacement of bridge bearers, transoms and decking. Maintenance of the suspension ropes, and replacement of bolts and steel bridge bracing was also undertaken. The total cost of the project was $470,000 and was supported through donations from people throughout New Zealand.

ATS Timber was chosen as the preferred timber supplier to this iconic project in conjunction with one of our Approved Resellers in Invercargill and the contractor Fulton Hogan. We also collaborated with engineers to come up with a viable solution to the unique requirements. Trusted Weka SG8 H5 timber products were supplied to replace the deck timbers, transoms, stringers and handrails to bring the icon back to its former .

 

Maungaturoto_Wharf_05

Maungaturoto Wharf

ATS Timber worked in with our local Approved Reseller to be the key supplier of specialised H6 treates Weka SG8 timber for the new wharf in Maungaturoto, Northland. A range of mainly 50mm sizes of H6 was used in the construction and to help fund it the locals came up with an innovative idea where you sponsored a deck plank on the wharf.

As part of the rural communities 150th celebrations a project was initiated called ‘Beautify Maungaturoto. This involved a lot of projects and one of the key stones of this was the construction of a new wharf.

The first European settlers to Maungaturoto came from England, arriving in Auckland in 1863 and coming north via boat to Mangawhai, then via bullock cart to as far as Kaiwaka.

The construction of the wharf paved the way for a re-enactment of this historic landing as one of the main events in the sesquicentennial celebrations.

Hauraki Rail Trail Bridges - Sustainability Award Finalist

Hauraki Rail Trail Bridges – Wins Sustainability Award

Congratualtions to Frame Group on successfully taking out the Sustainability Category of the NZ Timber Design Awards 2012. Trusted Weka SG8™ products were utilised in the innovative designs

The design and construction of 25 bridges ranging from 4m to 75m involving the use of ATS Timber Weka SG8™ Wet Radiata Pine timber has been selected as a finalist for the Sustainability Award in the NZ Wood Timber Design Awards 2012. The Hauraki Rail Trail is part of Nga Haerenga, the NZ Cycle Trail and was opened in May 2012.

A successful supply partnership with a local Approved Reseller who supplied the contractor saw ATS Timber products used extensively in the construction. Timber was chosen by Frame Group as an environmentally sustainable material and was a cost effective alternative to concrete and steel along with many other benefits that met the objectives of Nga Haerenga.

Radiata Pine timber was selected for construction of the many cycleway bridges because of the benefits over traditional steel or concrete options and the fit with the ecological and economic objectives of Nga Haerenga. Traditional bridge styling with modern connection detailing and prefabrication methods produced 25 attractive bridges ranging in length from 4m to 75m.

Short spans consist of pole beams, glue-laminated beams for longer spans, and timber suspension bridges provide the longest spans. Innovative barrier detailing facilitated prefabrication and efficiency of construction.

Radiata Pine timber was chosen because:

– Timber offers a lightweight option ideal for weak soils.
– Timber enabled construction in difficult locations without heavy craneage.
– Costs were significantly less than concrete, steel or hardwood options.
– Timber is aesthetically consistent with the railway theme, providing useful function and interesting form.
– The suspension, glue-laminated and pole bridges use common construction detailing, giving the structures a consistent appearance.
– The bridges were built with basic timber construction equipment and skills, hence small local contractors were involved in the construction.
– NZ-grown timber is an environmentally sustainable material, and its use supported the local industry.
– Timber bridges require minimal maintenance.

This project demonstrates the sustainability benefits and advantages arising from use of timber for recreational infrastructure, rather than more common steel or concrete options, and exemplifies the opportunities and sustainability benefits that arise from the considered use of NZ Radiata Pine.

Waimakariri_Footbridge_04

Waimakariri Foot Bridge

Crossing a small tributary to the mighty Waimakariri River, beside SH1, this arched footbridge used Weka SG8 products extensively in its construction.

Our Timber Consultants worked in closely with a Rangiora based Approved Reseller to provide a unique solution to meet the design and structural requirements.

Constructed by local contractors for the Waimakariri Council, it links two rest areas together on the side of the beautiful Waimakariri River in Canterbury.

A profiled handrail that was custom verified to Weka SG8 requirements, heavy section H5 timbers for abutments at each end, cut-to-length decking boards, handrail posts and balusters made up the supply of this project.

The Timber Trail

The Timber Trail

A feature article in this months ‘Progressive Building’ magazine by the New Zealand Institute of Building Inc. features The Timber Trail which is a section of the New Zealand Cycle Trail project. Trusted Weka SG8™ products were used extensively in this amazing section of the cycleway featuring more than 50 bridges with the longest being the Maramataha at 141m long and 53m above the ground. This is the longest suspension bridge to be built in New Zealand since the Arapuni Bridge in 1926.

The Timber Trail is an 85 km cycleway between Pureora and Ongarue. A 2-3 day cycling adventure on intermediate and easy gradients and surfaces, the Timber Trail is one of several cycleways developed as part of Nga Haerenga – the New Zealand Cycle Trail.

Utilising historic bush tramways, old bulldozer and haul roads, and newly constructed track, this Grade 2/3 trail features 35 bridges, including 8 large suspension bridges (the longest being 141 metres). It showcases the historic Ongarue Spiral, a marvel of engineering. It passes through magnificent podocarp forests of rimu, totara, miro, matai and kahikatea, as well as some exotic forestry and more open vegetation, offering extensive views of the surrounding landscape.

We offer cut-to-length timber and helicopter size packs for these specialist applications and recommend that timber is acquired in advance to allow for it to dry before being used in these types of structures. For more information on timber for bridges see our Weka SG8™ range.

Punakaiki_Veiwing_Platform

Punakaiki Viewing Platform

ATS Timber range of Weka SG8 products were chosen to construct the new viewing platform at the famous ‘Pancake Rocks’. Working in conjunction with DOC engineers and contractors and our local Approved Reseller.

Nature began this work of art about 30 million years ago. Over thousands of years, alternating layers of small marine creatures and sand became buried and compressed on the ocean floor. This created areas with multiple layers of hard limestone and softer sandstone. Earthquake activity then lifted the ocean floor high and dry, and those slow motion artists – the rain and the wind – began to erode the softer sandstone. The outcome is cliffs and ravines with hundreds of horizontal slices along their vertical faces, like huge stacks of pancakes.

In many places, deep inside the cliffs, narrow vertical air shafts created by the rain met with horizontal tunnels created by the pounding ocean. Today, around high tide, the ocean swells rush headlong through ever-narrowing tunnels and force large amounts of water and compressed air to race upward through the vertical shafts. The result is a hissing, heaving, thumping countryside that rhythmically emits geyser-like plumes of salt water. In a strong westerly swell, this creation of nature is a very impressive sight.

These are located at Dolomite Point, near the little settlement of Punakaiki which is located on SH 6, 40 minutes drive north of Greymouth and 50 minutes south of Westport.

Franz Joseph Glacier

Franz Joseph Glacier Viewing Platform

ATS Timber worked in conjunction with the structural engineer, DOC and our local Approved Reseller to come up with a solution for this stunning viewing platform over looking the Franz Joseph Glacier in Westcoast, New Zealand. Trusted Weka SG8 Wet H5 RS and PG products were selected for this application.

The Franz Josef Glacier (Ka Roimata o Hine Hukatere) offers visitors a rare opportunity to experience a dynamic glacier, in a temperate environment, within easy driving and walking distance from the main highway.

In the last ice age the glacier extended in a huge ice- sheet to beyond the present coastline. Today echoes of its frozen past are still apparent in the landscape. The terminal face of the glacier is less than 300 metres above sea level.

Today this glacial fed river has aggregated as bulldozed debris from the glacier have been washed downstream by rainfall (6 metres a year!) As you drive along the West Coast Road you will see rivers smokey blue water. This glacial silt is evidence of a glacier high in the hills.

Today Franz Josef Glacier Village’s natural credentials are impeccable and today there is a huge variety of natural attractions just a short distance from the Franz Josef Glacier Village. Lakes, rainforests, surging waterfalls and the glacial rivers of ice mean that the area is an adventure and leisure destination that is ready to be explored.
