Advancing Construction Prefabrication with 3D Laser Projection Technology
We’ve been hearing it for years; Construction needs to mirror manufacturing to achieve better efficiencies. For construction professionals this means moving work traditionally achieved onsite to streamlined, offsite production. Construction prefabrication carries the promise of reduced labor costs, increased building consistency, and dramatically reduced waste. As companies adapt to these business changes technology must adapt as well. This session will focus on how one company is applying and adapting traditional metrology and manufacturing techniques to achieve accurate, prefabricated, architectural assemblies and how these assemblies are finally installed onsite. Combining 3D laser scanning and 3D laser projection technology is revolutionizing predictability, budgeting, and quality control for the construction of complex projects. What used to require highly skilled labor and extreme assembly costs can now be executed with manufacturing-based workflows that leverage CAD, BIM, and site scan data for improved prefabrication results.
Force Multipliers: Moving Beyond the Supply Chain
The world now faces a shortage of bricks and concrete, while demand for new construction continues to grow. Builders are struggling to control costs with projects are plagued by delays and waste, the result of an antiquated supply chain that leaves contractors on the hook for huge cost overruns. While an estimated 40% of the cost to build a house goes into building material, another 20% goes into additional overhead costs ranging from shipping, site infrastructure, regulatory compliance costs; to say nothing of the delays that act like an anchor around the neck of the industry. The industry is in desperate need of a change if we hope to meet the demands of a world with a great and growing need for new construction. The current supply chain must die, construction must become more local. Every industry has seen this shift from traditional supply chains and labor pools, enabled by new technologies, but the construction industry has remained relatively unchanged. To cut costs from material, labor, and overhead, the industry must work to adopt technologies that make it easier to do more with less. We need force multiplier technologies for construction, solutions to extend the capabilities of fewer, less experienced contractors while making it easier to operate with limited infrastructure and resources near the build-site. Some of these solutions are already emerging, not from the construction industry, but from the Aerospace, Defense, and Advanced Manufacturing communities and the industry must find a way forward to bring these technologies to where they're needed. The industry needs to adopt technologies that make it easier to build anywhere. Automation and labor-extending solutions for a shrinking workforce, project management and site imaging technologies to more efficiently comply with government regulations and client needs, on-site material sourcing and manufacturing technologies to reduce the supply chain to the build site. The goal must be to move beyond the traditional supply chain, if this industry has any hope of keeping up with growing demand in a global market.
Reaching New Heights: Mass Timber Innovations
Energy use and carbon emissions from the built environment have been gaining significant attention worldwide. The construction of buildings across the world is currently dominated by concrete, but production of cement, a primary ingredient in concrete, is a major source of pollution, producing a ton of CO2 for every ton of cement. One approach to reducing the environmental impacts of construction involves increasing the use of materials with lower environmental footprints, such as wood. The development of Engineered Wood Products (EWP), such as Cross-Laminated Timber. have increased the possibilities of building with wood, allowing wood building to reach new heights. During this presentation Dr. Laguarda-Mallo will present the most relevant innovations in sustainable mass timber construction. She will explore different materials, analyze the current state of the North American Mass Timber market and present the most cutting-edge timber national and international projects.
