Building Below Grade in an Occupied Space

To mitigate disruption to tenants throughout the rest of the building, Choate coordinated closely with the buildings facility team on the construction schedule and critical path of this office renovation. As a solution, Choate worked off-hours throughout the project to alleviate the impact of construction noise during regular business hours.

As the renovation work was conducted below ground without exterior access, all construction materials had to be small enough to fit inside the elevator to be brought to the worksite. The subgrade factor presented an opportunity for the project team to get creative with the sequencing and material delivery schedule. Working with the design team, Choate created a schedule that facilitated materials arriving on site in smaller pieces in order to fit in the freight elevator. For example, all structural steel was delivered in smaller spans, and then assembled using hoisting equipment once inside the amenity space.
