The Downtown Los Angeles building was originally completed in 1926 and has since housed several owners ranging from a private club to, most recently, YMCA. When Proper Hotels purchased the property, demolition soon began. It was during this process the client realized their design model did not match the ceiling heights observed on site. This was an unexpected surprise, rendering the clients’ current RVT critically inaccurate.
Our laser scanning team was deployed to the project site to begin the meticulous work of measuring the gutted building, inside and out, with accuracy within”. The crew was working while the building was in the middle of demolition, and the project involved four phases of scanning to work around the other contractors. Close communication was critical for this logistically complex task.
The floor to floor height variations had its greatest impact on a new elevator planned to replace an existing staircase. A detailed laser scanning of the entire structure cleared any inconsistencies.
Accurate scans was crucial to keeping the project from going haywire. The scan uncovered that the design model and as-built model floor elevations differed by as much as of 10 ft. at around the 7th floor. Our team provided 2D views of all riser/structure clashes and arch design/as-built clashes for advanced coordination and resolution, avoiding costly field coordination.
