3.3 Continuity of Services.

To ensure continuity of essential services, the successful bidder must be prepared to fully commence work on the start date of this contract and should not assume that Government or previous Contractor employees will be available to guide, direct, or specifically orientate each Contractor employee.

3.4 Maintenance Level I (Basic & Routine Maintenance)

The Contractor must provide grounds maintenance services in maintenance level I areas at the times and frequencies specified in Attachment #1 the Summary Table below. Attachment #2 provides information of the size, location, and layout of the land parcels which make up maintenance areas.

Examples: Regular mowing, weeding, light pruning, debris collection, and general tidying.

Personnel: Basic knowledge required; often handled by general landscape maintenance crews.

Frequency: Weekly or bi-weekly, as specified in Attachment #1 the Summary Table below.

Objective: To maintain an orderly appearance and prevent overgrowth or early signs of decline.

3.4.1 Grass Cutting

Grass areas located at the ARTCC within this maintenance level must be cut to a uniform height between 2 inches and 2.5 inches at the frequencies specified. Grass areas located at the TRACON along the fence boundary within this maintenance level must be cut to a uniform height between 2 inches and 2.5 inches at the frequencies specified, other grassed areas at the TRACON must be cut to between 3 and 4 inches.

All grassed areas located within this maintenance level must be cut to a uniform height between 2 inches and 2.5 inches at the frequencies specified. If any bare ground within the limits of an area becomes vegetated with grass, weeds, or other similar growths through natural spread, it must be maintained as part of the basic contract. Prior to cutting, any trash, paper, or other debris that would detract from the finished appearance or present a safety hazard must be disposed of in the appropriate waste, recycling, and/or composting receptacles. Such debris includes but is not limited to paper, cans, bottles, limbs, pinecones, rocks, and other such objects within the maintenance area, and must include trash, paper, dead leaves, and other debris lodged in shrubs, hedges, fences, and along foundations and other walls. Debris must be disposed of off the activity the same day as collected.

Grass cutting is to be accomplished free of scalping, rutting, bruising, and uneven and rough cutting.

Cutting equipment must have sharp cutting edges which produce a neat, clean, even cut. Use of cutting equipment which is out of adjustment, thereby causing streaks or irregularities, uneven cutting, plowing, or gouging of the soil must not be permitted. Ground speeds and mower speeds must be synchronized to assure effective cutting action. After cutting, grass must have a uniform height. Grass clippings must not be windrowed or allowed to be deposited in piles or clumps. Grass clippings must be uniformly distributed over the mowed area. Grass areas close or adjacent to buildings, hydrants, parking lots, manholes, fences, trees, hedges, and shrubs are included in mowing requirements, and may require hand mowing.

Trimming around trees, shrubs, flower/shrub beds, cultivated areas, poles, walls, valves, and other similar objects must be accomplished to match the height and appearance of the surrounding mowed grass.

Trimming may be accomplished by hand clipping, by use of "weed eater" type equipment, or by herbicide treatment. Trees and shrubs must not be damaged by trimming operations. Trimming with herbicide treatment must be confined to an area extending 12 inches from the object being trimmed. Grassed areas, trees, or shrubs which are killed or damaged as a result of the Contractor's work must be repaired or replaced by the Contractor at no cost to the Government. Trimming operations must be considered a part of grass cutting and must be accomplished concurrently (same day) with grass cutting operations. Grass cutting will not be considered complete until all trimming operations are accomplished. Grass clippings and trimmings must be removed from sidewalks and other paved areas the same day the grass is cut.

3.4.2 Edging

All sidewalks, driveways, street edges, curbs, other paved areas, and shrubbery areas located within this maintenance level must be edged in accordance with the frequencies specified. Edging must create a l/2 inch wide and l inch deep clear zone immediately adjacent to the paved surface. All edging must be by mechanical means. The edging operation must include removal of grass and other vegetation which has encroached onto street and other paved surfaces from adjoining grassed areas. Where driveway or street pavement edge is not discernable due to grass encroachment, a straight and even line approximating the edge of pavement must be established and maintained. The edging operation must produce neat, clean lines along the sides of sidewalks and other areas edged, and must be accomplished free of scalping, rutting, bruising, uneven and rough cutting. All vegetation growing in the following areas must be removed during the edging operation:

1. Sidewalk and driveway expansion joints and cracks.

2. Street/driveway curbing expansion joints.

3. Cracks between curbing and street/driveway pavement.

For continued maintenance of vegetation growing in cracks and expansion joints, herbicide treatment may be utilized to reduce the amount of mechanical work. The use of herbicides must not be allowed for the purpose of eliminating or reducing normal mechanical edging along straight paved edges (sidewalks, etc.). Debris generated by edging operations, which falls on or is thrown on sidewalks, on curbs, in gutters, streets, or is thrown on nearby sod, causing an unsightly appearance, must be removed from the site the day of the edging operation, and disposed of the activity.

3.4.3 Plant and Shrub Pruning

Shrubs, bushes, hedges, and cultivated plants must be pruned at the frequency specified. All clippings and debris must be removed from the site the same day and disposed of, recycled, or composted off the activity [see Section 3.2.3.2 for waste management requirements]. Prune in early spring unless the shrub flowers before the end of June. If the shrub flowers before June, prune immediately after it finishes flowering. If the shrub flowers in summer or autumn, prune in winter or spring before new growth begins.

Pruning must be accomplished so as to:

1. Remove no more than one-third of the new growth at a time.

2. Reduce the size and growth rate of each shrub by clipping approximately 20% to 30% of the total surface area approximately 3 to 6 inches inside the normal "pruned surface". This interior clipping (20% to 30%) must be uniformly distributed over the entire shrub. This procedure must be performed as a part of the normal pruning operation (when new growth is removed). Evenly form and balance the shrub, bush, or plant in order to shape it according to its natural growth habits. "Box" or "circular" shaping is not acceptable, except with hedges. Hedges must be sheared or pruned, as appropriate, to maintain their established shape and appearance.

3. Remove dead, damaged, or diseased wood. If the entire shrub should die, remove the entire shrub to 6 inches below ground level. The hole and any other surface damage caused by removal must be filled with topsoil, fertilized, raked, and seeded.

4. Remove vines, tree sprouts or any other extraneous vegetative growth from under or on the shrubbery.

5. Prune or remove growth in front of windows, over entrance ways or walks, or where vision is obstructed at street intersections.

3.4.4 Cultivation and Mulching of Shrubs, Hedges, and Flower Beds Shrubs, hedges, and flower beds must be cultivated and mulched early spring (March to April), after the soil has thawed and late fall (October to early November) before the first hard frost. Ensure the mulch is applied after the soil has thawed in spring or after the first frost in fall. Aim for a layer of 2 to 3 inches, being careful not to pile it against plant stems or trunks. Cultivation includes weeding of shrubs, hedges, and flower beds. Cultivation must be extended a sufficient distance from bases of shrubs to ensure their protection from damage by lawn mowers, and trimmer/edgers, and to provide proper care for the plants, but in no case less than 18 inches. Removal of grass, weeds, rocks, and debris encountered during cultivation must be considered part of cultivation. All edges must be worked to a neat and true line. All timber, brick, concrete, aluminum, or plastic bed edging must be realigned as needed. Mulch in bed areas such as wood bark chips, pine straw, etc., must be well groomed after removal of weeds, rocks, etc.

Additional mulch, of the same type as existing, must be provided and placed around all shrubs and flower beds as required to maintain a minimum depth of three inches. Shrubbery without existing mulch must be mulched to a minimum depth of three inches.

3.4.5 Fertilization

Fertilizers must be used only if determined necessary by the COR, in order to minimize environmental impact. Synthetic chemical fertilizers must not be used. When fertilization is necessary as determined by the COR, fertilizer must be comprised of either recovered organic material or bio-based material.

Fertilizer comprised of recovered organic material must conform to the EPA’s Comprehensive Procurement Guidelines (http://www.epa.gov/cpg). Bio-based product listings are obtainable from the U.S. Department of Agriculture (USDA) (http://www.usda.gov). Fertilizer must be applied only when grass blades are free of moisture. Ground cover plants and shrubbery beds must be fertilized concurrently with lawn application, at the same rates. The Contractor's monthly work schedule must reflect planned fertilization dates.

All brush, weeds, and small trees (three inches and below in diameter at ground level) must be cut back to within one inch of ground level, removed from the site, and disposed off the activity. Any material to be saved will be marked by the COR prior to starting work. Any debris (i.e., limbs, dead trees, trash, etc.)

found in the underbrushing area must be removed from the site and disposed off the activity.

3.8.7 Tree Pruning

Trees must be pruned according to the following guidelines to selectively remove unwanted growth and encourage desired development. All tree pruning must be conducted under the supervision of a qualified individual provided by the Contractor, who is trained and experienced in proper tree pruning techniques.

Verification of this training and experience must be acceptable to the COR prior to the initiation of any pruning activities.

Before starting work, the Contractor must propose a pruning plan for each tree, which requires COR approval. Trees should be pruned in accordance with their natural growth habit to maintain a balanced form, promote health and growth, respond to damage from natural or human causes, and prevent interference with pedestrian and vehicular traffic. All clippings and debris must be removed and disposed of on the same working day as the pruning activity.

Clearance: Maintain a ten (10) foot clearance for all branches overhanging walkways and fence lines, and a fourteen (14) foot clearance for branches extending beyond the curb line into the paved section of roadways. Prune trees as necessary to ensure access, safe visibility for vehicles and pedestrians, and to prevent or eliminate hazardous situations.

Pruning must be accomplished in a manner to:

1. Remove dead, damaged, or diseased wood, or structurally weak limbs that may cause a safety hazard or unsightly appearance, including the removal of dead palm fronds.

2. Remove branches that extend over buildings and endanger roofs, eaves, and windows, or hang within eight feet vertically of sidewalks, parking lots, and driveways (10) ten-foot clearance vertically for sidewalks, (14) fourteen-foot clearance for parking lots and driveways.

3. Provide clearance for buses, moving vans, and similar vehicles along streets.

4. Cut back branches that overhang or grow into powerlines. Anticipate the effects of wind on branches which might fall on powerlines. Shape the entire tree rather than notch the top.

5. Remove growth of small trees in front of windows, over entrance ways or walks, and those which will obstruct vision at street intersections.

6. Remove sprouts which grow from the trunk. Remove sprouts to the height of the first major lateral limb.

7. Branch stubs must not be allowed. All branches must be pruned (removed) back to the next major limb or the tree trunk. Pruning cuts must be performed in a manner which leaves the branch collar exposed (with no stub beyond the branch collar).

3.8.8 Irrigation

Irrigation involves the artificial application of water to promote proper health, growth, color, and appearance of cultivated vegetation. Contractor must be WaterSense certified, and provide WaterSense certification to COR, prior to contract award. Grassed areas, shrubs, trees, and ground cover plants must be irrigated in accordance with the following directions. Only the ARTCC has an irrigation system. The ATCT and TRACON do not have irrigation systems.

1. Care must be exercised by regulating time and equipment to prevent wasting of water. Watering must be accomplished in a manner that avoids erosion, run-off, or ponding due to excessive quantities or rate of application. The minimum amount of water to be applied to all lawns, and planted areas must be one inch of water per application. Irrigation operations must be completed by 3:00 PM 6:00 AM daily.

2. The Contractor must be held responsible for any damage to plants, lawns, or buildings caused by careless handling of irrigation equipment. Sprinklers must not be set in such a position as to throw water into doorways, windows, porches, parked cars, parking areas, or to impede vehicular and/or pedestrian traffic.

3. Water will be furnished by the Government from the most convenient existing source of water. If a fire hydrant must be used for watering, clearance must be obtained from the COR before use.

All other required supplies must be furnished by the Contractor, except that Government owned and permanently installed sprinkler systems may be used where available. Where such installed sprinkler system equipment does not cover the area adequately, the Contractor must provide hoses and sprinklers to irrigate the entire area uniformly.

a. Sprinkler riser connections and sprinkler heads must be maintained, repaired, or replaced by the Contractor as necessary to eliminate obstructions, leaks, and other defects which would prevent proper operation, at no additional cost to the Government. Sprinkler heads must be maintained clear of dirt and other debris for approximately one inch around their outside circumference.

b. The Government will provide all other required maintenance to installed sprinkler systems due to normal wear and tear, to include time clocks, valve systems, and underground piping up to, but not including the sprinkler riser connection and sprinkler heads. Any damage to such systems caused by the Contractor must be repaired or replaced by the Contractor at no expense to the Government. The Contractor must promptly report damage to or malfunction of any sprinkler system to the COR.

4. Hoses, portable sprinklers, portable pipe, and similar irrigation equipment must be removed from lawn areas at the end of each workday or when not actually in use. All valves, covers, and valve box covers must be kept closed at all times except when in actual use.

5. The Contractor must abide by any local, state, or other water agency regulations or controls in force at the time of this contract.

6. For reimbursement purposes, irrigation must be ordered as follows:

a. Government System Application. When irrigation is ordered in an area covered by a government owned, permanently installed sprinkler system, the Contractor must be required to turn on or otherwise open and close valves as necessary to uniformly apply water to the area. One inch of water must be applied unless a specific application time is specified by the COR. As stated previously, in areas where the installed sprinkler system does not cover the area adequately, the Contractor must provide hoses and sprinklers to irrigate the entire area uniformly at no additional cost.

b. Contractor System Application. When irrigation is ordered in an area within 100 feet of a government-provided water source, the Contractor must provide hoses, sprinklers, and/or other necessary equipment to irrigate the entire area uniformly. One inch of water must be applied unless a specific application time is specified by the COR.

c. Site-Specific Application. When irrigation is ordered for a point of application (such as an individual tree or shrub) within 50 feet of a government-provided water source, the Contractor must provide hoses and/or other equipment as required to deliver 5-10 gallons per site, as specified by the COR.

d. Distant Site Application. When irrigation is ordered for a point of application (such as an individual tree or shrub) more than 100 feet from a government-provided water source, the Contractor must transport water and equipment to supply at least 20 gallons per specified site. The Government will furnish water from designated outlets, as specified by the COR.

7. Every year at the end of the normal growing season, the sprinkler system must be winterized. The system will be blown out with air by a qualified irrigation system technician. At the start of the growing season the sprinkler system must be pressurized with water and tested for leaks.

3.8.9 Ditch Cleaning

Vegetative growth in drainage ditches must be cut to a height of 6 to 12 inches on bottom and sides. All wood and brush cuttings, trash, and debris must be removed and disposed off the activity the same day of cleaning. Mouths of ditches, inlets, and outlets must be cleared of sediment, vegetation, and debris to allow unrestricted flow of water. Where ditch bottoms are paved, all mud and debris must be removed from the paved surface and disposed off the activity the same day of cleaning. Where ditch bottoms are not vegetated and have intermittent water flow, woody and aquatic vegetation must be removed or chemically treated. Approved herbicides for vegetation control will be permitted.

3.8.10 Tree and Shrub Establishment

Establishment must include providing necessary care to firmly establish the new plantings. All plants must be nursery grown and must bear certification indicating species, common name, and grade. Plants must be healthy, living specimens which are considered to be number one grade stock. Native plants and/or plants suited to the climate must be established, in order to minimize the need for irrigation and maintenance. Planting procedures must be in accordance with accepted nursery standards. The Contractor may invoice and payment will be made when initial planting is complete; however, the Contractor must water and otherwise care for new plants sufficiently to ensure proper development. All plants which die or fail to develop noticeable growth within one year of planting, must be replaced by plants of like size and type by the Contractor, at no additional cost to the Government.

3.8.11 Severe Shrub Pruning

Severe pruning of shrubs must consist of removal of all or a major portion of the total growth of the shrub. The extent of pruning will be indicated by the COR, but generally must consist of pruning large shrubbery to a level approximately one to three feet above ground level. Debris resulting from the pruning process must be disposed off the activity the same day of pruning.

3.8.12 Vegetation Removal

Vegetation removal must consist of the removal of grass, weeds, trees (less than three inches at ground level), and all other vegetative growth to ground or pavement level within 12 inches on both sides of fence lines. Mechanical methods of vegetation removal must be used. If mechanical methods are not feasible, chemical methods may be used with approval by the COR. If chemical methods are approved, the Contractor must submit Material Safety Data Sheets meeting the requirements of 29 CFR 1910.1200(g) and the latest version of Federal Standard No. 313, as stated in paragraph 3.2.3., for any hazardous chemicals to be used.

Debris generated by vegetation removal operations must be removed and disposed of off the activity the same working day[see Section 3.2.3.2 for waste management requirements].

3.8.13 Sodding

Sod must be dense, uniform, weed free, be certified to be free of disease, insects, and nematodes, have minimum thatch, and good sod strength. Strength will be assessed by lifting a piece by one end with no tearing and little stretching. It must have been mowed to a height of one to two inches within 24 hours of lifting. It must have soil depth of 0.5 to l.25 inches. Sod must not be allowed to become dry and when stacked it must not be allowed to heat up above l00 degrees F. Soil must be moist just prior to laying sod on well graded surface free of vegetation and properly prepared for accepting the sod. Sod blocks must be placed in rows butting each piece firmly against the last. Joints in successive rows must be staggered.

Slopes must be sodded by beginning at the bottom and laying sod in rows across the slope. Sod on slopes steeper than 2:1 must be held in place with wooden pegs. Immediately following placing, the sod must be rolled to provide firm contact with soil. Cracks must be filled with topsoil. As soon as this process is complete, sodded area must be irrigated by uniform application of one-half inch of water. No more than 60 minutes should elapse from the time sod is placed until it has been irrigated. The Contractor must provide the necessary care to firmly establish new grass growth and must water and otherwise care for sodded areas sufficiently to ensure proper development. All grass which dies or fails to develop noticeable growth within one year of sodding must be replaced by the Contractor at no additional cost to the Government.

3.8.14 Sprigging

Sprigs must be fresh, healthy, living stems (stolons or rhizomes with 50 percent or more of the stems being rhizomes) and attached roots of Bermuda grass or Zoysia grass. Sprigs must be obtained from approved sources where the sod is heavy and thickly matted, and free from ground pearl and fairy rings.

Sprigs must be free of nut grass (cyperus rotundus), Johnson grass (sorghum halepense), and other objectionable weeds, and must not contain material which might be detrimental to the development of the turf. Sprigs must be planted within 48 hours of harvesting. In addition, sprigs must not be left unprotected in the sun for longer than l5 minutes. Sprigs must be planted in l00 linear inches of sprigs per square yard on well graded surface free of vegetation and properly prepared for accepting the sprigs.

Distribution must be sufficiently uniform to ensure that the maximum spacing of sprigs must not exceed l2 inches. Immediately after opening furrows, sprigs must be placed and covered to a depth of approximately 2 1/2 inches after compaction, leaving a portion of each sprig protruding above the soil level. The furrows must be filled in such a manner that the surface is left even at the designated grade and compacted with a roller weighing 60 to 90 pounds per linear foot of roller. Sprigged area must then be watered not later than 30 minutes after sprigging has been completed. At least 1/2 inch of water must be applied over the area sprigged in a manner which will prevent erosion due to the application of excessive quantities in a concentrated area, and with watering equipment that will not damage the finished surface.

The Contractor must provide the necessary care to firmly establish new grass growth and must water and otherwise care for sprigged areas sufficiently to ensure proper development. All grass which dies or fails to develop noticeable growth within one year of sprigging must be replaced by the Contractor at no additional cost to the Government.
