    Grunley Hosts Mega Column Celebration

    On Tuesday, June 22nd, Grunley hosted a Mega Column Celebration at our Milken Institute Center for Advancing the American Dream, Phase 2 project! The afternoon event was held to acknowledge the significant achievement of installing the most critical steel that will allow our project team to erect the L5 addition on the existing 1503 historic building. The Mega Columns are W14x257 steel members and extend from the basement to the 5th floor of the 1503 building.
