BIM Modeling

1920s Plans + BIM

The Hall of Justice project is the renovation and upgrade of an existing County of Los Angeles building located in downtown Los Angeles. The historic Hall was closed in 1994 as a result of damage from the Northridge Earthquake. The $231 million renovation began in 2011.

The 335,000 square-foot project will feature 308,000 square feet of office space equipped with entirely new mechanical, electrical and plumbing systems that tie back into the existing central plant, among many other renovations and improvements. The Los Angeles County Sheriff and the District Attorney will be the new tenants occupying the building upon its completion in 2014.

The Hall of Justice was originally built in 1925, making the historical renovations integral to the success of this project for the tenants as well as the residents of Los Angeles County. Psomas used these 1920s era record plans for survey, layout and structural BIM modeling for this project, using Revit software. A BIM model was provided for each of the fourteen floors plus a penthouse. The project team will be pursuing a LEED Gold Certification for this design-build project.
