Precast concrete played an integral role in building the new B. C. Rail Yard Control Tower in North Vancouver, British Columbia. An important factor favoring precast concrete is the moldability, durability, predictable finish, and inherent stiffness of the material. Key features of this 50 ft (15.2 m) high tower are an elevator shaft made of nine vertically stacked hollow precast segments and a ... [Show full abstract] uniquely shaped precast concrete floor dish. The precast segments are bonded together with vertical reinforcing bars, post-installed in grouted ducts, designed to resist high seismic forces. The floor dish was cast on the ground and lifted into place, forming the control room floor. The result is a structurally efficient yet functional and aesthetically pleasing structure. This article presents the design challenge, conceptual design, design features, and erection highlights of the project with primary emphasis on the precast concrete components.
