Project Information
What will the project accomplish?
The Cannon Renewal project will focus on key building systems; heating, cooling, electrical, plumbing, fire and life safety, accessibility and structural integrity. Replacing or repairing systems and components will resolve numerous problems, such as plumbing leaks, plaster ceiling failures and falling pieces of exterior stone. The project will make the building far more energy efficient, comfortable and safe, while retaining its historic grandeur.
The scope of the work is indicated by the numbers and quantities of building elements to be repaired or replaced:
* 740 windows
* 510 lights
* Over 260,000 square feet of exterior marble (a total area larger than four football fields)
* Over 1.2 million square feet of plaster
* Almost 46-1/2 miles of piping
* Over 80 miles of conduit
* Almost 76,000 square feet of roof turned "green"
What is the schedule of the project?
The Cannon Renewal project is separated into five two-year phases, aligned with the Congressional move cycles. During each phase, portions of streets around the building will be partitioned off to create temporary areas for delivery trucks and space for workers to conduct their operations. During the initial phase, which began in 2015, utility infrastructure upgrades while occuring primarily in the basement and areas of the courtyard will support the remaining phases of the project.
In each of Phases 1-4, one wing (highlighted in the above graphics) will be closed to allow for installation of new building utility systems, restoration of historic elements, as well as construction of a completely remodeled fifth floor. Scaffolding will be installed on the exterior street and courtyard sides of the building while the damaged stone facade is restored. The restoration of the internal courtyard occurs during Phase 4, which includes the installation of a green roof.
What ensures that the project delivers good value to the taxpayer?
The AOC is committed to maximizing taxpayer value, reducing the risk of cost overruns and delays and minimizing disruption to the work of Congress. Careful definition of requirements during the initial steps of the project will help avoid future changes that may cause cost increases and delays. In addition, the AOC is incorporating lessons learned from other complex projects and implementing risk mitigation strategies. Similar projects have been conducted throughout the Executive Branch, including the Eisenhower Executive Office Building and the headquarters of the Departments of Interior, Justice, Treasury and Commerce. |
