Architect in writing prior to commencing work of any conditions deemed
unsatisfactory for the installation; installation of flooring materials is
understood as acceptance of the substrate as satisfactory.
3. Concrete: The
General Contractor shall be responsible for hiring an independent testing

recommended by the manufacturer at time of installation of the flooring or at
any future date. Moisture vapor emission and moisture content testing must
conform with the requirements of ASTM F-1869-11 (Calcium Chloride Test) and ASTM
F-2170-11 (Relative Humidity Probe Test). If any test result shows excessive
levels of moisture content or vapor emission rate, apply manufacturer�s
