Specifications include, but are not limited to: FALL AND WINTER MAINTENANCE: (a) Airport: (i) The Contractor shall begin snow control efforts at a time no later than when two (2) inches of snow or one–half (1/2) inch of slush have accumulated on runway or taxiway surfaces. In all cases, the Contractor shall begin snow removal efforts with sufficient time to allow completion of normal snow removal on the runway, taxiway and apron surfaces before the first scheduled air carrier flight departure or arrival. Snow drifts and berms will not be allowed to develop on the airport's aircraft movement areas (inside the edge lights or cones) unless the storm is so severe that reasonable efforts to remove snow are unsuccessful, at which time, snow removal operations may cease until the storm subsides to the point where snow removal efforts are effective. If such a condition develops, the Contractor will contact the Department representative. ; (ii) Runway(s) and taxiway(s) shall be plowed free of loose snow full width and length. Snow must be plowed until it is a minimum of twenty (20) feet and/or clearing the Runway Safety Area outside the edges of the runway(s). Snow banks will be placed off the edges and not on the threshold/ends of the runway(s).; (iii) Apron(s) will be plowed free of loose snow. Snow control on apron(s) will begin after the runway(s) and taxiway(s) have been plowed.; (b) Roadways: (i) Snow plowing operations will begin on roads only after airport snow control efforts have been completed. Snow control on roads need not begin until four (4) inches of loose snow has accumulated on the surface. Once roadway snow control has begun, snow and ice will be removed to the greatest extent reasonably possible.; (ii) During spring break up and periods of heavy rain, road shoulders and ditches will be graded and any debris removed to assist drainage. ; (iii) If provided by the Department, culvert thaw wires will be activated by the Contractor when surface ice appears in drainage ditches and be deactivated by the Contractor when spring thaw has begun. The Contractor will notify the Department representative before activating any thaw wires.; (2) SPRING AND SUMMER MAINTENANCE: (a) Airport: (i) All areas on the airport where aircraft operate, except private leasehold property, will be maintained clear of rocks two (2) inches or more in diameter and any foreign objects. These areas will be maintained free of holes or depressions that exceed 3 inches in depth that may affect directional control of an aircraft. Should potholes, ruts, etc. develop, they will be smoothed out as soon as possible. Aircraft Movement Area Surfaces shall be graded, free of rutting and potholes.; (ii) Once each summer, or as determined by the Department representative, all brush and weeds will be cut around the runway, taxiway lighting, threshold markers and SREB to ground level. The Contractor shall conduct minor brush cutting one hundred (100) feet beyond the edges of the runway and one thousand (1,000) feet beyond the thresholds/ends, unless these dimensions encroach upon other than airport property, in which case, cutting will terminate at the property line.; (iii) Once during the spring and once during the fall, the Contractor will assist the Department representative with full length and width grading of gravel surfaces. This shall be done to maintain smooth and consistently level surfaces in aircraft maneuvering areas. ; (3) ROUTINE MAINTENANCE: (a) Signs, Lights, Markers, & Reflectors: The Department is responsible for the initial placement of windsocks, threshold markers, runway lights, reflectors, and signs. The Contractor will be responsible for replacing any damaged, missing, or burnt out items of this type in accordance with Item P-660 and Attachment A. Light lens MUST be replaced with the same color and style as the original.; The Contractor will request from the Department representative any materials necessary to repair or replace these items. The Department will provide these materials unless the damage is due to negligence on part of the Contractor. In event these items are damaged by the Contractor negligence, the Contractor will replace these items at his sole expense.; During the Contractor's routine inspections, any of these items needing repair will be marked on the inspection list.; (b) Maintenance of State Equipment: Only persons authorized by the Department representative shall operate State furnished equipment. The Contractor shall assure all State furnished equipment is used only for airport and road maintenance associated with this contract. The Contractor will comply with the following: (i) Check coolant, hydraulic system, battery, air filter guage and oil levels before starting equipment to be certain that all are in the recommended operating range.; (ii) The equipment will be greased a minimum of once per week when being used. Transmission and final drives must be checked at this time. Check and/or replace oil and oil filters at factory recommended intervals. Used oil and oil filters shall be stored in suitable leak-proof containers within the equipment storage building. No material shall be dumped within or outside the building. The Department will be responsible for disposal of these materials.
