An engineer hired by contractor Perini Building Co. on Monday began spelling ways to permanently repair the unfinished Harmon Hotel as testimony concerning demolition of the CityCenter property resumed after a four-month hiatus.
Steve Schiller, president of John A. Martin & Associates, said computer models show an earthquake could cause loads to shift back and forth across floors four through seven, placing an extraordinary stress on some walls. Reinforcing the Harmon at certain key points would alleviate this shear reversal hazard, he said at the hearing in Clark County District Court.
A formal written plan has not been placed on the record. After the hearing, CityCenter attorney Steve Morris said his clients had received a cost estimate from Perini of $20 million, of which the contractor would absorb $4 million because of construction defects. Perini's plan places the bulk of the blame - and also repair costs - on CityCenter because of an alleged faulty design, Morris said.
