The first three floors and street-front of Dana's building were recreated as sets for filming, including the climactic earthquake scene where hydraulics were used to raise broken parts of the street. Broken pieces of pavement and the road were positioned outside the real location to create a seamless transition between the two shots. DeCuir said: "They had one night to dress the street. When people went home early in the evening everything was normal, and when the little old ladies came out to walk their dogs in the morning, the whole street had erupted. Apparently, people complained to the New York Police Department and their switchboard lit up." For the scene where Dana's apartment explodes outwards, Weaver stood on set as the explosion happened. Similarly, the scene of Weaver rotating in the air was done on set using a body-cast and mechanical arm concealed in the curtains, a trick Reitman learned working with magician Doug Henning.
