Olympic Construction for Olympic Games

Serial Information: Civil Engineering—ASCE, 1976, Vol. 46, Issue 6, Pg. 56-59


Document Type: Feature article

Abstract:

Montreal is preparing at full speed for the Olympic Games. The precast, post-tensioned concrete velodrome will seat 10,000. It will be available for conventions, public meetings, exhibits, etc. The spherical roof is made of prefabricated concrete arches. The roof was lifted by hydraulic jacks, which transferred the load from the falsework to the abutments. The roof was lifted in 2-in. (50-mm) increments. The cost of the Olympic Stadium for 70,000 spectators increased from an estimate of $100,000,000 in 1972 to a recent estimate of $564,000,000. Behind the dramatic increase should be included the novel technical design, especially the prefabricated curving columns, frequent technical changes, and poor labor relations. Misalignment of the precast, prestressed elliptical ring caused delays in construction.
