Largo is currently working on the seismic retrofit of a two level below grade precast concrete parking structure at the Paseo Colorado development in Pasadena. Located along South Los Robles Avenue between Historic Route 66 (Colorado Blvd.) and Green Street, the upgraded structure will provide support for the new commercial and hospitality space to be constructed above.
Largo’s team is busy drilling and epoxying dowels to expand footings and enlarge columns and using cast-in-place concrete to construct shear walls. With hundreds of corbels to be installed, a custom steel form was created so the team could efficiently pour these support structures. Foam inserts in the deck are being used to lighten the load along Green Street instead of a thickened slab where the structure connects to street level. Placing embeds for structural steel and forming and pouring a new vehicular ramp are also included in Largo’s scope. The work includes additional utility rooms, new pedestrian access stairs and elevators, and modified exhaust, lighting and fire protection systems. Working with general contractor CW Driver, Gonzalez Goodale Architects and Englekirk Structural Engineers, Largo’s scope is scheduled to be complete in early 2018.
