Today’s post comes from James Garvin, General Engineer at the National Archives
The replacement of the tier 20 upper roof at the National Archives Building (Archives I) began in mid-July. This project is scheduled for completion in mid-October 2012.
Each day, part of the old roof will be removed and the exposed area prepared for the installation of the new roof. Some noise will be generated when removing the old roof so to minimize disruption to employees and visitors construction activities will be scheduled in the early morning hours and will end by 9 a.m. each day.
The installation of the new roof may generate odors typical of roofing applications—the smell of hot tar. The contractor will make every effort to mitigate these smells from entering the building. Throughout the project, a large crane will be required for material lifts. We will work to minimize impact on building operation and use while the crane is in place.
We apologize in advance for any inconvenience, and thank you for your patience during this critical building repair. We do not anticipate any impact to public or employee entrances during the project.
