The construction of a 12-story cross-laminated timber building planned for Portland, Oregon, has been placed on indefinite hold as a result of changing market conditions, including escalated construction costs and fluctuations in the tax credit market.
One of Denver’s first cross-laminated timber (CLT) mid-rises has employed a rarely utilized means of groundwater control, known as ejector well dewatering. One of the benefits of this system is ability to lower groundwater to the maximum extent possible, allowing for the excavation and installation of the foundation mat slabs and waterproofing membrane in “near-dry” conditions.
A recent workshop on fire properties of materials concluded cross-laminated timber (CLT) and insulation applied to the exteriors of high-rise buildings are among the materials most in need of urgent research and development.
After a previous round of testing, WoodWorks, in cooperation with the USDA Forest Service Forest Products Lab and Softwood Lumber Board, conducted a second series of blast tests on two-story, single-bay CLT structures.
The Washington State Legislature has passed a bill requiring the Washington State Building Code Council (SBCC) update its codes to account for mass timber products, including cross-laminated timber (CLT). This revision will make it easier for developers to use the increasingly popular building material by adding certainty to the permitting process.
