Specifications include, but are not limited to: This project will support research and is funded by the National Science Foundation and United States Department of Agriculture. The research project is a collaboration between Oregon State University, Colorado State University, and Penn State University. The goal of the experimental program is to conduct three testing phases ofshake-table testing for a six-story mass timber building at NHERI@UCSD. This project reuses the bottom six stories of an existing 10-story mass timber test building to be tested prior to this six-story test program. The three testing phases include: 1.4.1 Phase 1: 6-story building designed with post-tensioned, U-flexural steel plates (UFP) wall solutions, designated as UFP-walls, for the East-West (EW) Cross-Laminated Timber (CLT) walls and the North-South (NS) Mass Ply Panel (MPP) walls. 1.4.2 Phase 2: 6-story building designed with post-tensioned UFP and buckling-restrained brace (BRB) wall solutions (EW CLT UFP walls and the NS MPP BRB walls). 1.4.3 Phase 3: 6-story building designed with a steel-braced frame wall solution (EW CLT UFP walls and the NS steel braced frame). 1.4.4 The research team is seeking up to three contractors to help with preconstruction planning and material installation/construction/demolition in four work packages (WP). 1.4.4.1 WP 1 involves working with already installed UFP-walls. Work will include swapping out UFPs on two CLT walls and two MPP walls. Installing rods and applying post-tensioning on the four walls of the 6- story building are to be considered as an alternate. 1.4.4.2 WP 2 involves the two MPP UFP-wall deconstruction and installation of two new walls (BRB-wall solution). Installing rods and applying post-tensioning on the two new MPP walls of the 6-story building are to be considered as an alternate. 1.4.4.3 WP 3 involves deconstruction of two BRB walls and coordinating with Simpson Strong-Tie on their steel braced-frame wall solution. 1.4.4.3 WP 4 involves demolition of the 6-story building, including coordination of stair removal and Simpson’s steel braced-frame wall removal.
