在Bisnow最近的一次网络研讨会上， Sustainable 建设 Creating More Sustainable Buildings at a Higher Value, 百家乐软件项目主管, 马修但是托内罗, spoke about the value and tremendous potential of mass timber in the construction and design industry. The focus of the webinar dove into the different benefits, 成本和挑战, as well as opportunities that mass timber presents. 其他小组成员包括:约翰·克莱因, 首席执行官, Generate; Colin Booth, 战略总监, Placetailor; and Wil Catlin, 董事总经理 & senior partner, Boston Realty Advisors as the moderator.

Mass timber is a broad industry that encompasses wood based structural framing members. 它没有被编纂, so it’s loosely used to describe many different types of structural building components including: Glued-Laminated Timber “Glulam” or “GLT”, 交叉层压木材" CLT ", 钉层压木(NLT), Dowel Laminated Timber “DLT” and others. All can be used in a myriad of solutions and have the capability to serve the purpose of floor, 屋顶和墙壁框架系统.

The panelists spoke about their own experiences working with mass timber and different variants. Here are three key takeaways from the webinar about mass timber and w在这里 it’s headed in the industry:

Contractors and designers need to be involved early in the process.

• The game changing aspect of mass timber buildings is that the complete structure including beams, columns and floor plates are prefabricated off-site. The structural floor plates need to have openings and edges of floor systems locked down because the material is fabricated using a CNC (Computer Numerically Controlled) process. 所有开口, cuts and geometry are fabricated off-site, and t在这里fore drive the contractor to plan projects early and be involved in the design phase from the start.
• Mass timber forces a change in the process as the buildings are digitally designed, requiring more upfront coordination with the parties involved. This forces us to examine more variables in a project and develop procurement plans earlier. 项目位置等因素, delivery routes and lay down space need to align with the owners’ goals of the project, in order to make planning a mass timber project a success.
• This is in addition to the usual coordination effort for locating openings, 管道系统和管道渗透, which has to be completed 12 weeks before the structure is delivered to the site. Any openings on the floor plans and anything in the shear walls must be drawn, dimensioned and programmed into a computer that controls robotic fabrication tools.

在未来的5-10年, New England has the capability to be larger than the west coast with mass timber.

• 交叉层压木材" CLT " is one of the first non-proprietary structural products in the U.S. 工程师可以在几十年内使用. Although t在这里 aren’t yet any Northeast manufacturers, CLT current can be sourced from places including Northern Quebec, 英属哥伦比亚, 蒙大拿, 阿肯色州, 俄勒冈州和阿拉巴马州. We have also been sourcing it recently from Germany and Austria. While the lack of availability locally in the Northeast seems to have caused a slower adoption to widespread use, 它正在迅速加快步伐.
• As interest increases and more projects are designed with CLT and Glulam, technology is being developed that allows designers to use systems that take into consideration the manufacturing properties and shipping limitations of the various vendors, 它们都有自己的分数, sizes and performance characteristics of the product.

Increased speed to get trade contractors in on projects.

• 在网络研讨会期间, Matthew gave an example of a building that 百家乐软件 worked on, when compared the schedule to a steel and concrete building, the mass timber structure allowed the superstructure to be erected 30% faster. Since the floor plates were constructed of pre-cut CLT structural panels, and openings were already prepared for HVAC and plumbing trades, the follow-on trade contractors were able to work from the floor plate long before they would have been able to from a steel structure that required forming and placing of the concrete on metal deck floor plate. 另外, the team was able to start on the exterior wall framing system sooner, and they could avoid temporary winter enclosures on the mass timber structure.
• 决定使用CLT地板板, glulam beams and columns was made at the schematic design phase since 百家乐软件 was able to showcase the benefits and efficiency of the construction provided by the prefabricated floor plates. The ultimate deciding factor for the design was the ability to install exterior walls faster and get ahead with the MEP trades.
