DESCRIPTION OF PROJECT:

The roadway surfaces shall be maintained 24 hours a day, 7 days a week, including Federal Holidays. Please see below for level of service requirements. Communication with the contracting officer’s representative (COR) will be paramount during the duration of this project.

When accumulative frozen precipitation events occur, the contractor shall clear frozen precipitation (snow/ice) to the extreme edge / shoulder of the roadway surface as well as use a 5/1 ratio sand / salt mix abrasive to de-ice precipitation that is not cleared to the edge of the roadway.

When non-accumulative precipitation events occur, the contractor shall use a 5/1 (or other approved ratio) sand/salt mix for roadway application, for de-icing frozen precipitation that cannot be cleared from the walkways and front steps. Types of non-accumulative precipitation would be freezing rain, heavy frost, or a minor accumulation of snow that cannot be removed by plowing. Special consideration shall be needed for intersections, hills, and curves. Special Consideration areas include the following:
