4 risk-management challenges of using cross-laminated timber in construction

Posted on by Shield Insurance Agency

cross-laminated timber |

In the last few years, a surprisingly conventional material has swept the sustainable building industry: wood. Cross-laminated timber (CLT) construction, a building method in which wood is layered to create a strong and durable frame, is now competing with traditional concrete and steel foundations. This method, which has become increasingly popular in Europe, is now making headway in the United States. According to the Globe News Wire, the industry is projected to grow by 12 percent between 2021 and 2027.

Construction companies, architects, and environmental advocates alike are embracing CLT because it’s more sustainable than traditional materials, durable, lightweight, and suitable for prefabricated construction projects. But this building method also poses new risk-management challenges for owners, builders, and insurance providers. In this article, we’re examining the challenges of CLT across multiple insurance lines—and sharing suggestions for contractors to help mitigate potential risk.

Challenge 1: protecting the project during construction

In terms of builders’ risk coverage, CLT has some benefits. Because it can be built off-site and transported, the method can result in shortened building cycles, which means contractors may save money on insurance costs. However, builders will need coverage in the event of fire or water damage. CLT is made entirely of wood and—even though the material has been proven to burn slowly in fire tests—it is at a higher risk of fire damage than more traditional materials. On top of that, staining and charring of the wood from water and fire damage can cause aesthetic issues, and project owners might require builders to replace the panels even if the building is still structurally sound.

How to mitigate risk: contractors should ensure that CLT is pre-treated with a fire retardant before building. It’s also crucial that all members of the building team understand transport, storage, and staging best practices to limit exposure to the elements.

Challenge 2: evaluating environmental risks

When it comes to environmental risks, CLT has a leg up over traditional building materials. Although CLT is bonded with glue, most manufacturers use formaldehyde-free adhesives to improve air quality and reduce off-gassing. However, when building with CLT, construction companies should take notice of potential water damage and subsequent mold exposure risks. The 2021 International Building Code allows for CLT buildings up to 18 stories—but these taller buildings are exposed to the elements for more extended periods during construction, increasing the risk of water damage and mold growth. If property owners discover mold, contractors may be liable for any damages or associated health risks.

How to mitigate risk: builders should treat CLT with water repellents, particularly on the end-grain where the wood is more porous. During construction, using tent structures that cover exposed materials can also reduce the risk of water damage that can lead to mold growth.

Challenge 3: understanding cross-laminated timber performance capabilities

Because CLT is a newer material for many builders, design-build contractors should take special care to ensure their designs are structurally sound and materials meet quality standards. Both designers and builders should reference and comply with the applicable International Building Codes and stay up to date on evolving research. For example, as this study highlights, the shape and number of layers of CLT can influence the risk of delamination, in which the adhesive holding boards together fails and can put a structure at risk.

As an example of delamination, work came to a halt on a $79-million building under construction at Oregon State University after two layers of CLT floor panel came unglued and fell. While the incident did not cause any injuries, it did result in a several-month-long investigation, extensive rework to replace the damaged panels, and a delayed opening.

By staying informed on CLT performance capabilities, designers and builders are better able to build safely and on schedule and help mitigate the risk of damage, work delays, and related builders’ risk and liability claims.

How to mitigate risk: designers and builders should ensure that building codes align with the use of cross-laminated timber. Using building information modeling (BIM) during the planning process can also help ensure that all stakeholders—including owners, designers, engineers, and architects—are on the same page during the project.

How technology is transforming the construction industry

Posted on by Shield Insurance Agency

In today’s construction industry market, there’s little doubt that technology holds transformative power.

Not only have new technological advancements led to greater efficiency in day-to-day operations, but they’ve also created new opportunities for companies to gain a competitive edge and focus on strategic growth.

There are several ways technology is making positive impacts on key priorities within the construction industry, including workforce, safety and risk management, and operational efficiency.

Finding solutions for construction industry labor challenges

Labor shortages in the construction industry remain significant and widespread. A new survey by the Associated General Contractors of America (AGC) found that 80 percent of construction companies report having a tough time filling hourly craft positions, representing the bulk of the construction workforce. On top of that, 56 percent also are finding it difficult to fill salaried positions. According to AGC, preparing, attracting, and re-skilling the future workforce are necessary steps in reducing that figure – and technology can help bridge the gap.

How can technology help with labor shortages? First, investing in cutting-edge approaches can help recruit and retain more young adults from tech-savvy generations into construction careers. Second, technology can streamline labor needs. By adopting tech methods to reduce on-site work time, such as using virtual construction tools like Building Information Modeling (BIM) and automating inventories and the ordering process, a contractor can better manage productivity levels and its workforce.

Addressing construction industry safety and risk

According to the latest Construction Technology Report by JBKnowledge, almost 50 percent of today’s contractors now have dedicated IT departments, and more construction companies are using technology solutions to internally manage workflows like estimating, project scheduling, and project management as well as to improve safety. Here are some of the ways technology is helping with efficiency and safety:

  • Wearables.

With wearable technology’s popularity and growth in consumer markets, the construction industry is now considering how to use different features to improve worksite safety. Some potential applications for wearable technology include monitoring an employee’s movements or vitals and providing real-time alerts if work conditions become dangerous. Smart helmets, for example, turn traditional hardhats into on-the-ground safety systems that can detect a worker’s level of fatigue or a worksite’s carbon monoxide level or temperature.

As another example, gear like augmented-reality glasses can provide workers with real-time guidance and detect errors before an accident, which, along with the proper training, could help improve productivity and safety.

Plusses like these will likely fuel more experimentation with wearables and research on their effectiveness at improving safety. Nearly two-thirds of insurers, for example, expect wearable technologies to have a significant impact in coming years, according to a survey of more than 200 insurance executives.

  • Mobile devices.

The importance of mobile capabilities has soared, the JBKnowledge report shows, with 83 percent of firms surveyed saying mobile is “important” or “very important” to their operations vs. just 59 percent who thought so in 2012.

The daily use of laptops in the construction field also has increased, from 64 percent in 2015 to 78 percent in 2017. And the use of smartphones, tablets, and other portable devices is quickly streamlining much of the construction process, from creating and approving blueprints to post-construction monitoring.

In terms of safety benefits, the adoption of mobile technologies enables real-time communication with all members of a construction team as well as faster incident reporting and injury documentation, all of which can help reduce the risk of injuries and the cost of worker’s compensation claims.
