1. Remove snow from sidewalks. 2. Remove ice & packed snow by salting and/or scraping. METHOD OF REMOVAL Contractor may use a shovel, blower, blower or blade mounted on a "garden" tractor, or a "skid steer" (not to exceed 3,000 lbs.) to remove snow. Lightly packed snow, caused by the machine being used for removal, or by footprints, and loose or powdery snow, that the machine or tool being used is unable to remove, will have to be "broomed" or scraped" to the extent that at least 90% of bare concrete is exposed. Sidewalk with 50% or more of the surface area covered with ice and/or hard packed snow, may be cleared by application of salt, or salt mixed with sand, and then scraping. Salt shall not be used in place of "shoveling"; salt shall only be used after receiving permission to do so from the Department of Public Works. Bid price shall include removing lightly packed snow on top of the ice and/or hard packed snow. The Contractor will supply the salt.
