Washington National Cathedral

Visitors Gateway Underground Bus and Parking Garage

This project consisted of the construction of below grade car and bus garages adjacent to the historic National Cathedral. The bus garage consists of slip ramps off Wisconsin Avenue leading to 18 bus parking spaces below grade, and the car garage has 4 underground levels with 427 parking spaces. Access to the grounds and the Cathedral is provided by two glass elevators at the North Lawn so as not to inhibit the site lines of the Cathedral. APM was selected by the National Cathedral at the completion of the Design Development Document Phase and immediately faced a severe overage of the Owner’s mandated budget. Collaborating with the Architect and Contractor, APM managed an initial value-engineering exercise to reduce the construction cost by $3.0 million. The Cathedral is open year-round, holds daily and weekend services several times each day, and schedules numerous special services through the year. Due to the extremely high volume of buses, cars, and nearly 700,000 visitors and worshippers annually in addition to staff and students, the planning and coordination of pedestrian traffic patterns and the development of an interim traffic plan were critical in regards to both functionality and safety. APM took the lead to assess the existing occupancy conditions and developed a traffic and signage plan so both the Owner and the Contractor could cohabitate onsite in harmony.

“In my 37 years of leadership and management experience, the APM team serves as a shining example of “how to do it”.”
