PART 2: SCOPE OF WORK/ SERVICES, ADDITIONAL RERQUIRMENTS,

CLARIFICATIONS AND INFORMATION

2.1 SCOPE OF WORK/SERVICES

The Contractor must field verify all new and existing dimensions indicted in this contract, the work site(s), the specifications, and the drawings before ordering materials and/or performing work.

For the planting beds listed below, the following work is to be performed in line with this contract, and any specifications and drawings provided.

BASE: Specifications for this pertain only to the drawing entitled, “Long Bed – East”.

Clear, Grub, Stump Grind and Removal: The contractor shall remove and dispose of all trees, stumps, roots, shrubs, grass, weeds, fallen timber and other surface litter, in this planting bed area. In addition to existing visible planting material, the contractor shall remove old stumps and plant material (including roots) prior to installing new plantings.

Grading: After plant material is removed, each area shall be finish graded and made ready for plant installation. The grade shall be minimally higher towards the center and sloped towards all edges to ensure positive drainage and discourage a standing water condition. The contractor may need to add up to five yards of garden soil to create the correct slope. For quality assurance, the contractor must provide a submittal of the material to the COR for inspection/approval, prior to installing. The contractor will summon the Contracting Officer’s Representative (COR) to inspect the grading once completed prior to moving forward.

Weed block/matting/fabric: Landscape weed block/matting/fabric shall installed and be black polypropylene polyester blend, 28 mills, 3.33 ounces/sq. yard, Mullen burst strength: 250 lbs.

Permeability is 28 gals/s.f./min. per fallen head method. Landscape fabric shall be DeWitt Pro 5 Weed

Barrier (1-800-325-0950) or approved equal. Landscape fabric shall be installed per manufacturer’s specifications in this plant bed, and shall be staked at all ends/edges and at a minimum of every three feet on center. Landscape fabric shall not be visible, and all loose ends shall be cut off, tucked under, or otherwise covered with three inches (3") of wood chips by the Contractor. Landscape fabric shall be in direct contact with soil. An “X” pattern will be cut in the fabric for each planting hole, and fabric shall be

“closed” and staked as close to the plant as possible to discourage weed growth. For quality assurance, the contractor must provide a submittal of the material to the COR for inspection/approval, prior to installing.

The contractor will summon the COR to inspect weed block/matting installation before moving forward.

Hardware cloth barrier installation: Contractor shall install ½ hardware cloth on top of the landscape fabric. Hardware cloth shall be a “galvanized after welding” product. Hardware cloth shall be staked at all ends/edges and at a minimum of every three feet on center. An “X” pattern will be cut in the hardware cloth for each planting hole, then “closed” and staked as close to the plant as possible to discourage pest activity. For quality assurance, the contractor must provide a submittal of the material to the COR for inspection/approval, prior to installing. The contractor will summon the COR to inspect hardware cloth barrier installation before moving forward.

Staging/Planting: The contractor must use healthy, pest/disease-free and atheistically pleasing stock to complete this work. The contractor will notify COR after plants are staged, but before planting holes are excavated to ensure plants are arranged in line with specifications. Contractor will amend planting backfill as appropriate for the health of plants and according to plant needs. Contractor will install appropriate fertilizer tablet(s) with each plant. Any excess soils are to be removed and disposed of. For quality assurance, the contractor must provide a submittal of the material to the COR for inspection/approval, prior to installing. The contractor will summon the COR to inspect the planting installation before moving forward.

Irrigation Work: The contractor shall install drip irrigation for all plants. The contractor shall be provided a designated point of connection (POC) to connect the system. The contractor shall install a circulating (grid style) drip irrigation system for each planting area. Product used shall be Netafim

Techline (or similar). From the soil type/texture/structure and plant material the Contractor shall determine the correct irrigation line size, gph and emitter spacing for the planting area. All irrigation tubing shall be staked at a minimum of every three feet. For quality assurance, the contractor must provide a submittal of the material to the COR for inspection/approval, prior to installing. The contractor will summon the COR to inspect the irrigation installation, and test/confirm the system as operational, and before moving forward.

Bark/Mulch: The contractor shall install a 3” layer of bark/mulch as topdressing throughout all planting areas. Screened organic bark/mulch, blond in color shall be used. For quality assurance, the contractor must provide a submittal of the material to the COR for inspection/approval, prior to installing. The contractor will summon the COR to inspect the bark/mulch installation before moving forward.

OPTION #A: This work is located in an area directly adjacent to the work designated in the Base work area.

Removal of 66 Plants: These plants are two years old, and due to declining health have not grown in vigorously. 40 of these plants were one gallon size when installed and the other 16 plants were five gallon size when installed. These shall be designated by COR and shall be removed by contractor.

Landscape flags shall be placed at each planting hole after each removal to distinguish the two plant types. Bark shall be raked away from plant before removal takes place to maintain and retain clean/weed free bark/mulch. Care must be taken to keep existing landscape fabric and hardware cloth in good condition while completing removal work and to ensure that loose soil from plant removal does not settle on adjacent bark/mulch areas and/or on the adjacent weed fabric. Before new plants are installed, contractor shall summon the COR to confirm this condition. After COR approves, the contractor can then install new planting material as specified below.

Install 66 New Plants: New plants to be installed are 66 one-gallon size plants. 40 plants shall be Cistus salvifolia 'Prostratus' and 16 shall be Salvia leucantha. The contractor must use healthy, pest/disease-free and atheistically pleasing stock to complete this work.

For quality assurance, the contractor must provide a submittal of the material to the COR for inspection/approval, prior to installing.

Care must taken to ensure: 1) that loose soil from new plant/planting operation does not settle on adjacent bark/mulch area and/or on weed fabric; 2) to keep existing landscape fabric and hardware cloth in good condition; 3) and to ensure existing irrigation tubing is not damaged. Before bark is moved back into place, contractor shall summon COR to inspect to find these conditions. After COR approves, the contractor can then move bark back in place. An additional three yards of bark/much (as specified above) shall be used to renew areas directly adjacent to new plants. The contractor will summon the Contracting

Officer’s Representative (COR) to inspect this work when completed.

Bark shall be raked away from plant before removal takes place to maintain and retain clean/weed free bark/mulch. Care must be taken to keep existing landscape fabric in good condition while completing removal work and to ensure that loose soil from plant removal does not settle on adjacent the bark/mulch area and/or on weed fabric. Before new plants are installed, contractor shall summon the COR to confirm this condition. After COR approves, the contractor can then install new planting material as specified below.

Install 32 New Plants: New plants to be installed are 32 one-gallon plants. These 32 shall be Salvia clevelandii.
