City officials gathered Saturday morning to mark the 36th anniversary of the L’Ambiance Plaza collapse. L’Ambiance, a 16-story apartment building, was being built using lift-slab construction, in which the concrete slabs are poured on the ground, then lifted into place using jacks. On April 23, 1987, a slab slipped and the structure collapsed, killing 27 men and one teenager who was working at the site with his father. Lift-slab construction was later banned in Connecticut. Renaissance Plaza, a four-story affordable housing complex now stands on the site, and a statue commemorates the L’Ambiance victims.
