1800 Larimer - Denver, CO

The facility at 1800 Larimer is a 22 story, 500,000 square foot office complex that will be the new headquarters for Xcel Energy. The project is a Certified LEED Platinum Level project, one of the first in the Colorado region. The site is located in downtown Denver and has four levels of underground parking. Various methods of shoring were used to ensure a safe excavation, including lag & beam and hydraulic shoring.
