3.2 Grounds Maintenance - CLIN X001 FFP

3.2.1. The Contractor shall perform grass mowing, edging, trimming, and raking in accordance with the maintenance level of the area to be serviced. Services shall, to the extent possible, be performed on a regular basis, for example, weekly on Wednesday, every second Wednesday, or the second Thursday of each month. See the PWS Attachment 1, GMP, for frequency of services.

3.2.2. Grass Mowing: All grassed areas located within each maintenance level shall be mowed to a uniform height that is specified for that level. Additionally, any bare ground within the limits of an area, which becomes vegetated with grass, weeds, or similar growths through natural spread (i.e., not artificially planted), shall be maintained as part of the contract.

A. Prior to mowing, the Contractor shall remove any trash, paper, or other debris that would detract from the finished appearance of the cut or present a safety hazard. Such debris includes, but is not limited to, paper, cans, bottles, limbs/branches, pinecones, rocks, and other such objects within the maintenance area, and shall include trash, paper, and other debris lodged in shrubs, hedges, fences, and along foundation and other walls. Debris shall be disposed of off the Center the same day as collected.

B. Grass mowing shall be accomplished free of scalping, rutting, bruising, and uneven and rough mowing. When mowing ditches, grass clippings should be either bagged or distributed away from the sides of the ditch to eliminate the accumulation of grass clippings in the ditch or on its sides. After mowing, grass shall have a uniform height. Grass clippings shall not be windrowed or allowed to be deposited in piles or clumps. Grass clippings shall 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. The Contractor shall ensure that grass clippings are not blown into storm drains.

C. Trimming around trees, shrubs, flower/shrub beds, cultivated areas, poles, walls, valves, and other similar objects shall 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. Trimming operations shall not damage trees and shrubs. Trimming shall be accomplished concurrently (same day) with grass mowing operations. Grass mowing will not be considered complete until all trimming operations are accomplished. Grass clippings and trimmings shall be removed from sidewalks and other paved areas on the same day that the grass is mowed.

3.2.3. Edging: All sideways, driveways, street edges, curbs, other paved areas, and shrubbery in Maintenance Levels I & II areas shall be edged in accordance with the frequencies specified in PWS Attachment 1, GMP. Grass clippings shall be removed from all driveways, pedestrian walkways, and steps. The Contractor shall ensure that grass clippings are not blown into storm drains.

A. Edging shall create a ½ inch wide and 1-inch deep clear zone immediately adjacent to the paved surface. The edging operation shall include removal of grass and other vegetation which has encroached onto street and other paved surfaces from adjoining grassed areas. Where a driveway or street pavement edge is not discernible due to grass encroachment, a straight and even line approximating the edge of pavement shall be established and maintained.

The edging operation shall produce neat, clean lines along the sides of sidewalks and other areas edged, and shall be accomplished free of scalping, rutting, bruising, uneven and rough mowing.

B. All vegetation growing in the following areas shall be removed during the edging operation: (1) Sidewalks and driveway expansion joints and cracks; (2) Street/driveway curbing expansion joints; and (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 shall not be allowed for the purpose of eliminating or reducing normal edging along straight paved edges such as sidewalks, curbs, driveways, and streets. Debris generated by edging operations, which falls on nearby sod, causing an unsightly appearance, shall be removed from the site the day of the edging operation, and disposed of off Center.

3.2.4. Cultivation of Plant Beds: Shrubs, hedges, and flowerbeds shall be cultivated at the frequencies and times specified in PWS Attachment 1, GMP. The bed shall extend a sufficient distance from base of shrubs, not less than 18 inches, to provide proper care for the plants and to insure their protection from damage by lawn mowers or other equipment. When cultivating, the Contractor shall ensure that the roots of all remaining plants are not damaged. All debris shall be removed from bed areas, disposed of properly, and shall not be turned under. All unwanted vegetation shall be removed in its entirety including the entire root system. Removal of all vines and unwanted vegetation growing throughout shrubs shall be included in the cultivation process.

3.2.6. Plant, Shrub, Tree, and Hedge Pruning: Plants, shrubs, trees, and hedges and cultivated plants shall be pruned at the frequency shown in PWS Attachment 1, GMP. The Contractor shall remove and dispose of all clippings and debris from the site and off the Center on the same day. Pruning shall be accomplished to:

A. Remove growth attaining a length of 4 inches.

B. 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%) shall be uniformly distributed over the entire shrub. This procedure shall be performed as a part of the normal pruning operation (when new growth is removed).

C. Evenly form and balance the shrub, bush, or plant to shape it according to its natural growth habits. “Box” or "circular" shaping is not acceptable, except with hedges.

Hedges shall be sheared or pruned, as appropriate, to maintain their established shape and appearance.

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

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

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

Maintenance on Perimeter Fence Line: NPR 1620.3, Physical Security Requirements for NASA Facilities and Property, Chapter 6 defines the requirements for security areas, as designated by the COR, and protective barriers at NASA LaRC shall be maintained as unobstructed areas or clear zones. The Contractor shall maintain unobstructed areas or clear zones on both sides of and between physical barriers at NASA LaRC. This shall be accomplished by removal of all trees, brush, rock piles, and other materials within the designated zone and the frequent mowing of vegetation or the use of chemicals designed to control or kill such vegetation. Vegetation shall not exceed 8 inches in height. These areas shall be kept free of vehicles, structures, and debris. Protective barriers outside clear zones shall be 10 feet or more from the perimeter fence, protective barrier, and any exterior structures, vegetation, or any obstruction to visibility.

D. Herbicide Inspection: If, at the end of the manufacturer’s recommended allowable time for a product’s ability to kill the vegetation, the application has not achieved at least a minimum kill of 90%, the Contractor shall re-perform the work at no additional cost to the Government.

E. Broadleaf Weed Control for Lawns: Rate of application for broadleaf weed control shall be as recommended by the manufacturer. A kill rate of 85% of all broadleaf weeds shall be accomplished within 3 weeks after application. This shall be determined by choosing random locations around the area of applications, measuring approximately 10 feet x 10 feet, and noting the percentage of visible broadleaf weeds both prior to and subsequent to the application of the broadleaf weed control. If the above kill percentage of broadleaf weeds is not achieved, the Contractor shall re-apply the broadleaf weed control as many times as required to achieve the required percentage of kill. Any required re-application shall be at no additional cost to the Government.
