Much CityCenter work done without engineer OK

After inspectors at the CityCenter site uncovered structural problems and code violations, a review of inspection reports has revealed much of the work at the MGM property has proceeded without engineer approval.


In the wake of uncovered structural defects, a review of private inspector reports for the $8.6 billion CityCenter construction project on the Las Vegas Strip shows construction moved forward in hundreds of instances without engineering approval.

The review--conducted by the Las Vegas Sun --shows that in many cases, contractors worked from drawings that had not been approved by Clark County, even though they affected the structural integrity of buildings at the site. According to county spokesman Dan Kulin, county inspectors usually review the "noncompliance reports" to verify that a project is built to code.

On Feb. 6, county officials had ordered MGM Mirage—owner of the CityCenter—to verify that the site’s towers were structurally sound. The order landed six months after inspectors uncovered significant structural defects at one of the seven buildings on the site. The engineer of record on the project had raised concerns; subsequently, the county found that 15 floors of reinforcing steel at the Harmon had been improperly installed. Such problems had been missed by the third-party private inspection firm hired by the property owner.

As a result, the county is now requiring different third-party private inspection company examine the structures and—in order to avoid further delays and cost overruns caused by the rebar problems—MGM Mirage is shortening the affected building by 21 floors.
