Contractor will provide all necessary labor, materials and equipment to perform on-call maintenance of pavement markings and traffic control devices as outlined below on an as needed basis. The Contractor will be notified of the need for work by written notice on a location-by-location basis. The services requested by this IFB will be exclusively used for maintenance work, as defined by 290.210 RSMo. This IFB does not cover construction, as defined by 290.210 RSMo, or major repair. The term major repair, for the purpose of this IFB, is a repair that is done by overhaul or replacement of major constituent parts that have been damaged. Replacing roofs, tuck-pointing buildings, and replacing air conditioning compressors are examples of repairs. If the size, type, or extent of the existing facilities is changed or increased, the work performed shall constitute construction and be subject to the Prevailing Wage Law. A project shall be considered to be maintenance work, as opposed to major repair, if the maintenance is the recurrent, day-to-day, periodic or scheduled work required to preserve or immediately restore a facility to such a condition that it can be effectively used for its designed purpose by repair but not replacement; and the size, type or extent of the existing facility is not changed.
