Contractor shall stage ladders and scaffolding as to allow free access to main front entrance to building at all times. All necessary precautions shall be taken to provide safe passage at the point of entrance/exit (contractor may be required to construct temporary safety passage to catch debris that could fall on individuals entering and exiting the building).

The contractor shall have delivered, handling and storage of all materials by the manufacture’s specifications.

Pre-Installation conference shall be required with Prime Contractor, Owners Representative, Flooring Contractor and/or Manufacturer's Representative to review the following: Evaluate slab conditions and extent of repairs necessary for Contractor to begin normal preparation and installation of seamless flooring.

Evaluate detail conditions at all penetrations, terminations, perimeter and drain locations. Detail problems shall be documented and resolved prior to floor installation.

Test concrete sub-floors using the Calcium Chloride test method to verify that slab moisture vapor transmission rate does not exceed manufacturer’s recommendations.

The Flooring Contractor shall provide an add option cost as part of the bid for the treatment of substrate moisture vapor transmission in the event the substrate exceeds manufacturers recommendations. Slab testing shall be performed immediately prior to floor installation so as to achieve the nearest real time conditions. Any slab developing readings of 3 pounds of water per 24 hours per 1000 square feet or greater by ASTM F-1869-98 shall receive Integral Concrete Waterproofing which shall be compatible with flooring and approved by the Flooring Manufacturer. Waterproofing shall be installed by a contractor that is certified by the manufacturer of the waterproofing material.

Assure that the existing floor and substrate are dry and exhibit no signs of previous moisture problems. Remove loose and deteriorating flooring to expose sound substrate and patch back to original elevation prior to prep of the remaining surface. Thoroughly prepare the remaining floor using terrazzo grinding or another prep procedure approved by the manufacturer.

The contractor shall remove and dispose of Government property, all items indicated as TO BE REMOVED. Such items become the property of the contractor and shall be loaded, transported per applicable DOT regulations, and disposed of at approved landfills.
