Back of House (BOH)

Mission Task Execution Spearhead Change Order Scope of Work located on Levels 1 through 4.

Scope of Work - BOH

SWJV identified a “scope gap” for the area between the Pedestrian Bridge and Concourse B, also known as, “Back of House” (BOH). SWJV selected Spearhead to perform this work and BOH Change Order (CO) #2 reflects the additional scope.

The BOH CO #2 consisted of installation and finish of gypsum walls and ceilings in areas throughout Levels 1 through 4, including:

Stairwell Lobbies

Escalator

Elevators

Control rooms

Electric closets

Additional, areas included:

A roof access corridor , stretching across the escalator, connects the BOH areas on Level 4 to the exterior of the building. The line of demarcation between Concourse B and BOH scope of work occurs at the corridor ceiling and expansion joints between both areas.

A suspended ceiling below the access corridor conceals the walkway with upturned, flared returns.

A feature wall on Level 3 encapsulates the northern face of the elevator lobby. The gypsum partition transitions into a rounded, GFRG corner, continuing to the foot of the escalator.
