Construction has commenced on the 415 Natoma project, also known as 5M-H1. This 25-story, 750,000-square-foot core and shell structural steel office high-rise is beginning shoring and mass excavation for the two basement parking levels. The 10-story podium features eight terraces with 15,000-square-feet of open space on the 10th floor. The structure then steps in before topping off at 380 feet with a 9,000-square-foot terrace overlooking the San Francisco skyline. A floor-to-floor height of nearly 15 feet will make this a one-of-a-kind office building in San Francisco. The expected completion date is August 2021.
The 5M Development, located between Mission and Howard at Fifth Street, includes three new buildings and a large landscaped open space. In addition to H1 there is M2, a 20-story apartment building, and the planned 30-story N1 condo project. The development, financed by Brookfield Properties, will do a great deal to revitalize the neighborhood and create a new mixed-use anchor in this part of the city.
The project is currently fine-tuning structural steel and curtain wall design while running full-bore through MEP coordination. Swinerton will self-perform the drywall scope—640,000 square feet of leasable office space—a great opportunity for our Special Projects group. Protecting an existing, occupied historical structure on site (five stories over a basement) and coordinating logistics with the parallel construction of the M2 Building has certainly kept the team on its toes. We are excited and motivated to hit the milestone of ‘BOE’ at the end of the year.
