Technical Note ETN-D-5-18
4 pp.; 2018
This Technical Note provides a summary of a recent study that compares the cost of the structural frame of a hypothetical 10-story residential building located in the Pacific Northwest using cross laminated timber (CLT) and cast-in-place reinforced concrete. The study was performed by the structural engineering firm Cary Kopczynski & Company, Seattle, WA (see the Reference section below for the report that was generated from this study).
Axonometric and plan views of the CLT option are given in Figures 1 and 2, respectively. Similar views for the reinforced concrete option are given in Figures 3 and 4. A typical floor to ceiling height of 9 ft-0 in. was assumed in both options.
Additional cost data for some actual CLT projects are also provided.
