6. Handicap lifts, one hour per quarter unit.

B. For each hour of monthly preventive maintenance that is not provided by the Contractor, as detailed in Section A above, the time must be documented and accounted for as identified below.

1. Hours missed due to unforeseen circumstances may be made up the following month, but at no time shall the monthly hours owed for previous quarter of PM maintenance exceed ten percent (10%) of the required man hours over a three-month period.

2. Accurate record keeping is the responsibility of the Contractor. The Contractor must provide to the Contract Administrator, or designee, a representative proof of preventive hours utilized, at a minimum in a monthly report, or upon request.
