Timber Bridge Repair: A Roadmap for Success

Tags:

The timber bridge has been a cornerstone of transportation and commerce for centuries, providing an essential infrastructure to link communities. But over time, wear and tear can take its toll on any structure. That is why timber bridge maintenance and timber bridge repair schedules are important to keep up with. Over time, like all bridges timber bridges experience wear and tear from usage, and sometimes abuse from their users. This results in the bridge beginning to weaken and eventually breaking down. Thankfully, there are ways to repair these aging bridges so that they can continue to serve us. In this blog, we’ll discuss the process of creating a repair and restoration plan for timber bridge repair, exploring the step-by-step project management and techniques and materials used to restore these essential links.

1. Inspecting the Bridge

The first step is to inspect the bridge to determine, the issues the timber bridge is experiencing, and what areas causing it to underperform or that are experiencing failure or issues. Though it’s the first step, it’s the most critical to creating a maintenance and repair plan. Identifying the true condition and threats your timber bridge is experiencing. An initial visual inspection can do wonders for surface-level condition views, but the facts are within each pile, member, and element in the structure. Things to consider here are the testing, and inspection methods that are utilized to help give you a clear picture of where your bridge stands.

Once you’ve identified potential problem areas from your visual inspection, we need to assess the extent of the damage that the bridge has undergone. This will help you understand your structure, and develop a plan for repairing the bridge and will also give you an idea of how much work will be involved. Credentials are an important aspect for the firm that is selected to execute the inspection; which is why we’ve pursued to earn and maintain the highest level of standards as an inspecting and lab testing facility for timber over the last 30 years. Our IAS-accredited lab, non-destructive testing methods, are a winning combination when it comes to timber bridge inspections. There are other accrediting bodies, but we chose the IAS accreditation because it is highly renowned and known for its high standards and auditing requirements.

2. Understanding the Issue

The next step in the creation of your timber bridge repair, or maintenance schedule is to assess and understand the inspection report and data sets from the inspection. This is why it’s critical to select a consultant engineering firm and inspection firm that will provide clear and precise data represented in its reports and what the data tells you regarding the issues your bridge is facing. Understanding the issue that you are dealing with is critical to heading into the next step of the process.

There are a variety of different issues that can cause timber bridges to become damaged or underperforming, and it is important to identify the specific issue that you are dealing with to repair it properly. This is why it is often best to hire an engineering firm that specializes in timber bridge repair and maintenance. They can provide detailed information on your structure as well as advice and guidance on the right methods to address any issue or damage that you find.

3. Developing a Plan

After you have thoroughly read over the timber inspected the bridge, and identified the issues your timber bridge is facing, the next step is to develop a plan for repairing it. This is where the firm you select for your inspection is critical because an experienced and trustworthy firm will provide in-depth analysis along with their data to where it’s summarized and easy for you to understand along with providing repair recommendations if you ask for them.

Any firm that turns a report back to you as a finished report and provides lots of readings from tests and data collected but doesn’t provide a detailed analysis for you is one you should avoid. Just like bridges and buildings, not all engineering firms are built equally. Some firms will provide shotty or overly complicated reporting to ensure that you go through them and either complete a more expensive than necessary repair or make it so that you have a very limited understanding or details about how you can repair your bridge.

You will need to consider the extent of the damage and identify any potential weak points to create an effective plan of attack. This plan should include a detailed description of the work that needs to be done, as well as a timeline for completing each repair and sequences that need to be executed before starting and before moving to the next phase. When creating a plan for your bridge it’s important to note that factors need to be considered for example how certain repairs need to be done to get access or complete a repair this can either help or affect other areas of the timber bridge in terms of loads and stress.

4. Acquiring Materials and Equipment

Once reached this phase of the timber bridge repair, it’s going to come down to logistics and procurement that suits you best when it comes to handling this step. You have your plan of attack for repairing the bridge, the next step is to acquire the materials and equipment needed to complete the repairs. This will include both raw materials and hardware along with potential other elements that some people don’t consider that may not be on your radar. For example, if you have manpower but no specialized construction or training, you may need to hire a company for project management depending on the size of the project or specialty subcontractors.

5. Making Repairs

Once you have acquired the necessary materials and equipment, the next step is to begin making repairs to the bridge. This process will vary depending on the type of damage that has been done, but it is important to follow your repair plan carefully to ensure that the repairs are made correctly. If there are repairs that are specialty or require specific applications of products for example our preferred tiber restoration and mass timber construction company is Timber Restoration Services. After all of the repairs have been made, it is important to complete them by sealing or staining the repaired areas. This will help to protect the repairs from further damage and will also give them a finished appearance.

6. Checking and Testing Repairs

Following the completion of the repairs, it is important to check and test them to ensure that they are structurally sound. This can be done by putting weights, and reading equipment to record performance data on the repaired sections of the bridge or using other testing methods. If any problems are found during this process, additional work may need to be done to fix them. It is important that any testing or inspections be conducted by a certified inspector who understands timber bridges and how to properly inspect them. This will help to ensure the safety and performance of the structure. Once inspections and tests are completed, the timber bridge can be opened back up for use.

7. Maintaining Your Timber Bridge

Once you have completed all of the repairs, it is important to maintain the bridge regularly to prevent further damage from occurring. which means regular inspections yearly, Vonditate reports every 5 years, as well as comprehensive structural analysis, completed every 10 years. Completing these regular checks and steps will help you reduce costs as well, as reduces the time an asset is inaccessible or down.

Conclusion

In conclusion, repairing a timber bridge is an in-depth process that requires careful planning and attention to detail. Following this roadmap will ensure your success every time. With the right approach, timber bridges can serve us for generations. It is critical to have an engineer inspect the bridge regularly, and make sure all necessary repairs or restoration works are completed. Doing so will help you keep your timber bridge in top condition for years to come. The key is making sure you work with an experienced and trustworthy firm that provides a detailed analysis of their findings as well as repair recommendations. Keeping your timber bridge in good condition is essential for the safety of everyone who uses it, so make sure to take the necessary steps to ensure its structural integrity.​

Understanding Durability & Strength of Timber

Durability encapsulates more than just the material’s lifespan. It’s about maintaining structural integrity over time against a suite of challenges. Existing heavy dimensional timber structures are different than modern Mass timber products, such as cross-laminated timber (CLT), glued-laminated timber (glulam), and dowel-laminated timber, are renowned for their exceptional strength and stability. Engineered with precision, they offer performance that surpasses that of raw materials. Pound-for-pound timber is the strongest building material available on the market. But existing heavy dimensional, and timber structures still offer extremely reliable and strong options for structures and can still provide great service to communities around the globe.

Lifespan of Timber

Timber structures can have a lifespan equivalent to or greater than concrete and steel when properly cared for. Understanding the threats to this lifespan is the first step in protecting it. Like with all building materials certain aspects can heavily influence a material’s behavior and lifespan.

Effects of Moisture and Rot

As with any wood product, prolonged exposure to moisture can lead to decay and rot. This is mostly concerned with Wood exposed to open air with a moisture content level of greater than 24%. Timber and wood submerged in water doesn’t apply to this because the main component of the decay process is excessive moisture in combination with oxygen, which due to the lack of oxygen the integrity of the timber member underwater isn’t affected.

Properly designed and constructed timber structures can mitigate the effects of moisture by utilizing vapor barriers, drainage systems, and ventilated cavities. Regular inspections and maintenance can also prevent moisture buildup and catch any potential issues early on, through the use of diffusers and other methods.

Insect Infestation

The best defense against insect infestation is a proactive approach that includes regular inspections, treatment options, and sealants that can deter insects from entering the wood. Additionally, using pressure-treated wood for any areas that may come into contact with the ground can also prevent insect damage.

While termites are a well-known threat to wood structures, other types of pests can also cause damage. Marine borers, for example, are small molluscan EG. shipworms or crustaceans like limnoriids that feed on wood and can be found in marine environments such as docks and piers. They can weaken the structural integrity of timber, making it susceptible to failure over time.

Another type of pest that affects timber is carpenter ants, which can tunnel through wood and weaken its structure. Lastly, wood-boring beetles are also a common pest for timber structures, as their larvae feed on the inner layers of wood and can cause significant damage if left unchecked.

By understanding these pests and implementing preventative measures, such as regular inspections and treatments, you can protect your timber structure from potential infestations and ensure its durability for years to come. Overall, it’s important to actively monitor and address any pest threats to maintain the strength and longevity of your timber investment.

Proactive Protection Strategies

Now that we understand the potential threats to timber durability, let’s explore proactive strategies to protect your wood structure and extend its lifespan.

Design Considerations

The first line of defense against durability issues begins with proper design considerations. This includes incorporating moisture management systems, using fire-resistant materials, and considering climate-specific conditions when choosing materials and coatings. The most critical and overlooked aspect are design details for a structure. This factor alone can cut the lifespan of structure by decades.

Regular Inspections and Maintenance

Regular inspections and maintenance are critical to identifying potential issues before they become major problems. It’s essential to establish a schedule for inspections, repairs, and maintenance tasks such as sealant applications or replacing damaged panels.

Coatings and Sealants

Coatings and sealants not only protect against moisture but also provide an extra layer of defense against insects and fire. Be sure to use coatings and sealants specifically designed for timber, as they differ from those used on traditional wood products.

Education and Training

Finally, education and training are crucial for ensuring the proper care and maintenance of a timber structure. This includes educating construction workers on best practices during assembly and offering training programs for building owners on how to maintain their investment properly.

Future Research and Innovation

The path to improving heavy dimension timber and mass timber durability is an ongoing one. We must continue to push boundaries through research and innovation.

The Quest for Sustainability

Innovation must be coupled with sustainability. Research into eco-friendly treatments and coatings is essential for long-term support of heavy timber and mass timber’s ecological promise.

Advanced Monitoring Technologies

Emerging technologies offer non-invasive ways to monitor the health of your timber. Integrated monitoring systems can provide real-time data, alerting you to potential problems before they manifest.

Working Together for Longevity

By taking proactive steps and working together, we can ensure the long-term durability of heavy timber and mass timber structures. This not only protects our investments but also promotes sustainability and a more environmentally friendly urban landscape for generations to come. By understanding the potential risks and implementing proactive strategies, we can safeguard these exceptional structures for generations to come. 

Together, we can build and protect a brighter future with timber. So let’s continue to use this remarkable material responsibly, investing in its maintenance and durability for the sake of our environment and communities.

FRANK LLOYD WRIGHT'S "WINSPREAD"

Wingspread was designed by Frank Lloyd Wright and built in 1938-39 as the residence of Herbert F. Johnson Jr. The house is now used as a conference facility by The Johnson Foundation. The home is centered around a large domed living room. However, like many of Wright’s designs, it pushed the limits of the structural systems that were available at the time of construction. Due to excessive snow loading and remodels which removed shear walls, the exterior bearing walls had pushed outward and the roof of this dome had begun cracking. In partnership with Robert Silman Associates, WRD engineers developed a replacement rafter system that would maintain the aesthetic appearance from both inside and outside while greatly increasing the strength. The system that was developed consisted of several layers of epoxy-coated carbon-fiber-reinforced plastic (CRP) face-bonded to laminated veneer lumber (LVL).

FT. RILEY

Wood Research and Development (WRD) was selected to complete a level II bridge inspection of the Keystone Wye Interchange which consists of two timber highway bridges, the 411 (lower bridge) and the 412  (arch bridge).  Non-destructive tests, including stress-wave timer testing, were carried out to find the health of the main timber structural elements.

The first building in Austria to incorporate Dr. Tingley's FiRP® technology was successfully completed through collaboration among various partners. These included the owner, Blaha Family from Vienna, the architect and engineering firm RW Tragwerksplanung, also from Vienna, the laminator, and the engineering team from Wood Research and Development in America, who provided valuable consultancy.

With a footprint of 1,700 m2, the building utilized 73 m3 of glulam beams, out of which 56 m3 were curved beams. The roof main girders consisted of 10 FiRP® Glulam beams measuring 20 cm x 100 cm x 26 m, specifically BSH 14 quality, featuring 2 layers of aramid fiber reinforcement (ARP). The roof side girders were of the same size but remained unreinforced.

To minimize timber transportation, the project required only 11 truckloads, including the prefabricated wood elements used for covering. Each trip covered approximately 400 kilometers, with consideration given to reducing transportation costs through beam size optimization. The structure was erected within a span of 15 days, marking a successful milestone.

THE NEST

The NEST, a natural science and learning center situated in Bradenton, FL at the Robinson Preserve, offers more than just educational experiences but also serves as a versatile event space, available for public rentals such as weddings, parties, and various other events. Although the structure was constructed in 2018, it encountered challenges early on in 2022 stemming from the type of connectors and seal/preservative treatments employed during its initial construction. Needing help and looking for answers, Officials at the NEST reached out to WRD looking for an analysis and inspection of the facility to provide clarity and answers to their problems. Our timber inspection team and Wood lab testing teams worked, diligently to address these issues. Following inspections and analysis conducted by WRD, we were able to help guide them in the right direction by providing detailed lab results and structural assessment reports to find the best repair plan possible based on cost, timelines, and quality of repair for the structure's health.  Per our recommendation the client reached out to our preferred masstimber repair partner Timber Restoration Services to complete the glulam repair. Sourcing glulam beams from the Southeastern US to perfectly match the existing species within the structure TRS then expertly manufactured the required beam lengths in-house. For the restoration process, Their team strategically removed only the ends of the damaged joists to optimize material and installation costs. Employing a mortise and tenon connection method, TRS seamlessly integrated the new joists with the existing elements, resulting in a structurally sound timber connection that remains concealed from external view.

SOUTH ARM BRIDGE

The South Arm Bridge is located in New South Wales, AU. The old timber bridge has been an iconic symbol of the town since it symbolized the progress of the town of Byron Shire from a logging, shipping port to a popular tourist destination. This two-lane, 7 span bridge was built in 1958-1959.

With a community heavily invested in environmental issues it made perfect sense to restore and upgrade the bridge back to its former glory. Using data gathered by our inspection team, Wood Research and Development put together a design plan to upgrade the existing bridge from 10 tonnes to 44 tonnes, recycling the existing timbers wherever possible. The existing piles were restored, and a new superstructure was installed.

THE WAVE

Dr. Tingley, an esteemed consultant from WRD, provided invaluable expertise in the realm of design modeling, introducing the groundbreaking FiRP technology. This innovative technology has revolutionized various technical aspects, earning widespread recognition for its versatile and innovative capabilities. With its unique properties, FiRP has unlocked limitless possibilities for incorporating lightweight and aesthetically pleasing designs into architectural projects.
One remarkable example that showcases the transformative power of FiRP is the Austria Center Vienna. With Dr. Tingley's guidance, this technology seamlessly integrated into the design concept for the center's overhang and entrance. The incorporation of FiRP not only enhanced the overall aesthetic appeal of the building but also pushed the boundaries of design possibilities. The pivotal role of Dr. Tingley's consulting expertise ensured the resounding success of this project.

BELLDOME

Dr. Dan Tingley was one of the senior design engineers for this 12-story domed building called the Belledome. This is New Brunswick’s largest domed building. Construction of the plant began in 1986 and it was completed in 1988 and is used to store coal for an electric power plant. Steel is not acceptable for such structures, because of s02 (sulphur dioxide). At 450 MW, it is designed to burn coal which is delivered by ship through the Port of Belledune and occasionally by rail or truck.

PROVIDENCE BRIDGE

The Providence Road bridge is a five-span timber vehicle overpass over a Canadian Pacific Railway line near Oshawa, Ontario. In June 2013, Wood Research and Development (WRD) performed an inspection of the bridge and made recommendations for a repair strategy. Beginning in October of 2013, Timber REstoration Services (TRS) completed the retrofit and replacement of the bridge. The repairs included in-place restoration of the substructure and complete replacement of the superstructure and deck. The replacement superstructure consists of glulam timber girders, a transverse glulam timber deck, and a crash-tested timber guard rail system. The complete bridge has achieved a CL-625-ONT load rating.

DILLMANS BRIDGE

The Dillman Bridge in Meaghers Grant was put out for tender in 2019 as a Design-Build project. The old bridge had been decommissioned for over two years after a vehicle accident on the bridge rendered the bridge unusable. This forced the
local residents to take a 17-minute detour. The bridge site is located in one of the highest exposed and embedded corrosion zones in the world, making steel and concrete products much more susceptible to the elements than timber. Upon winning the tender, Timber Restoration Services contracted Wood Research and Development for the design work.Wood Research and Development designed a 35 m long by 7.6m wide with a load rating of CL-625, tu gas a TL-4 crash proof rail system and an Alaskan Yellow Cedar handrail. The substructure consists of driven timber piles with a glulam timber back wall specifically designed for timber bridges.

The superstructure is comprised of glulam laminated deck panels sitting on eight glulam girders which have two fixed end movement connections that were assembled onsite. The use of High Strength Fiber (FiRP®) and advanced techniques make this lightweight option not only a cheaper alternative but also provides additional longevity.  All fasteners and hardware are hot-dipped galvanized.

TILLAMOOK AIR MUSUEM

Wood Research and Development (WRD) was selected to complete a level II bridge inspection of the Keystone Wye Interchange which consists of two timber highway bridges, the 411 (lower bridge) and the 412  (arch bridge).  Non-destructive tests, including stress-wave timer testing, were carried out to find the health of the main timber structural elements.

KEYSTONE WYE

Wood Research and Development was commissioned by Stantec Engineering to complete an inspection on the Keystone Wye
Interchange which consisted of two timber highway bridges. Analysis of the structure has determined that the bridges are in good shape with some restoration and maintenance required. WRD designed a fix involving diffusing all timber elements with SWT Readings in the yellow and red zones to arrest decay, epoxy-filling gaps between girder and the road deck and continuing the process of cleaning and staining the surface of the timber. It was recommended that a follow-up of non-destructive testing
should occur within two years of the original testing. Following the recommendations should prolong the useful life of the structure for another 50 years.

ROGER BACON BRIDGE

A huge cost saving on this project was the use of the existing piles. Found through inspection to be in great condition, the piles allowed Wood Research And Development (WRD) to place a 3-lane bridge where an old steel two-lane bridge existed previously. This was made possible due to the lightweight property of timber. Using existing piles would not have been possible with the weight of concrete or steel. The cost savings with this are estimated at nearly $1 million. Timber Restoration Services (TRS) was retained from NS TIR to produce a design-build bridge to replace the existing 48-year-old steel arch bridge. Being located in the highest embedded and exposed corrosion zone in Canada, many elements of the bridge were rusted out and failed. The bridge had been taken out of service and slated for replacement. TRS teamed up on this project with WRD, who took care of the design aspect and construction oversight for the project. WRD had tested the existing 80-year-old timber piles of the existing structure and determined that with little restoration, these piles had enough capacity to support the new structure and would go another 80 years. TRS manufactured and installed the three-pinned arch glulam timber arch which is the longest three-lane, timber clear span bridge in Canada. The design incorporated the placement of a 500-tonne crane on the jump span to install the timber arches.

THE MILL

Wood Research and Development (WRD) utilized their extensive expertise in timber structural engineering and heritage building assessment to conduct a thorough analysis of the old Cotton mill, built in 1902, with the aim of determining its feasibility for conversion into a mixed-use building. Their team of experts, boasting over 100 years of experience, meticulously assessed the structural integrity of the mill, considering factors such as load-bearing capacity, durability, and potential renovations required to meet modern safety standards.

Following their detailed structural analysis, WRD formulated a comprehensive design and refurbishment plan tailored to the specific needs of Mississippi State University and the City of Starkville, MS. Their creative solution involved repurposing the mill into a versatile space that would accommodate retail, commercial, and event facilities. The plan incorporated innovative design elements while preserving the historical aspects of the building, highlighting the rich heritage of the cotton milling industry in the region.

Through their expertise and careful evaluation, Wood Research and Development provided valuable insights and recommendations to ensure the successful transformation of the Cotton mill. Their commitment to combining technical excellence with respect for heritage resulted in a well-crafted design and refurbishment plan, aligning with the vision of Mississippi State University and the City of Starkville, and creating a vibrant, functional space for various activities.
