100 CLT UK Projects

The study data was acquired from an industry report prepared by Waugh and Thistleton (2018) and funded by the Softwood Lumber Board & Forestry Innovation Investment. The report is entitled “100 UK CLT Projects” and showcased a wide array of CLT projects between the years 2005 and 2018. For each project, the following information is provided: general description of the project, schematic drawings, project renderings or real photos, abstract construction data, the project type, the project team, and the structure type. This study depended mainly on the project team composition data. The team of each project included a firm or more of the following stakeholders: architect, structural engineer, main contractor, timber engineer, timber contractor, and timber manufacturers. The report information was coded in a tabular format to capture the structure type and the collaborating team data for each project. First, a project data table was created to assign each project a unique identification number and provide the following data fields: structure type and the project team firms. It should be noted that some project teams involved multiple firms of the same stakeholder type, e.g. a large or complex project may involve multiple architects, engineers or main contractors. Second, the unique firm instances are filtered from the project records and assigned unique identification numbers. Third, a data matrix structure was created to relate each project (as rows) to the involved team stakeholder firm (as columns). There were a total of 261 project stakeholders involved in these projects, including: 73 architecture, 58 structural engineering, 74 main contracting, 31 timber engineering, 10 timber contracting, and 15 timber manufacturing companies. To perform the longitudinal analysis, the projects and their stakeholder firms were organized in four time periods.
