If not adequate, Contractor shall sawcut as needed. 2. Demolition and Disposal o Break up, remove, and properly dispose of existing concrete slabs. o Contractor is responsible for preventing damage to adjacent slabs. Contractor shall notify the City of any pre-existing adjacent slab damage (e.g., corner breaks) before commencing breakout. o Penalty: A minimum $100 deduction will be assessed for damage caused by the Contractor to adjacent slabs. o The City recommends perimeter saw cutting of all slabs to minimize breakage into adjoining slabs (not mandatory, but strongly advised). o Contractor shall remove no more slabs than can be placed and finished within three (3) calendar days. 3. Subgrade, Unsuitable Soil, and Base o Provide a 4-inch base of MoDOT Type-5 aggregate, compacted in accordance with St. Louis County Standards for Highway Construction. o Where bad/unstable soil is encountered, Contractor shall remove and replace with 4 inches clean rock to subgrade and seal with 4 inches of 1-inch minus in preparation for the new slab. o Contractor shall contact the City Inspector at all stages to verify need and quantities. o Bidder shall provide a unit price for unsuitable soil removal and replacement. 4.
