Revised: 26 January 2023 (yellow highlights)

D.1 BACKGROUND

National Park Service (NPS) National Mall and Memorial Parks (NAMA) Dwight D. Eisenhower Memorial (DDEM), located at the base of Capitol Hill at 540 Independence Avenue SW. The four-acre urban park features a variety of pieces that symbolize Eisenhower’s inspirational feats during his time as the supreme commander of the Allied Expeditionary Force in Europe during World War II and as the 34th U.S. president. The newly constructed Memorial was commissioned September 17, 2020.

D.2 PURPOSE

The Dwight D. Eisenhower Memorial is a unique structure serving as a work of art, a memorial of significant emotional power, and a functioning park with landscaping and sculptures. Each of these aspects presents major challenges to the performance of this contract. In combination, they require considerable orchestration of contractor resources coupled with a deep sensitivity to the significance of the memorial and the concerns of the general public.

The contractor shall provide all labor, personnel, equipment, supplies, facilities, transportation, tools, materials, supervision, management, and non- personal services necessary to perform operations and maintenance, preventative maintenance, service calls, and repairs (minor and major) for all equipment, systems, facilities, and grounds designated to the Dwight D. Eisenhower Memorial as defined in this Performance Work Statement except for those items specified as Government furnished property and services. The contractor shall perform all work to the standards in this PWS.

D.3 SCOPE

This is a Single-Award Indefinite Delivery/Indefinite Quantity (ID/IQ) contract that encompasses all activities associated with the operations, maintenance, and repairs of the Dwight D. Eisenhower Memorial. Attachment 2 provides a list of the Dwight D. Eisenhower Memorial equipment and systems to be maintained under this contract.

The inventory is illustrative of the types of equipment and systems to be maintained under this contract. During the life of the contract, individual pieces of equipment or complete systems may be replaced. The Contractor is responsible for maintenance of replacement equipment and systems. As a work of art, the maintenance and repair requirements demand special care because of the construction materials, e.g., Spanish Lime Rock, stainless steel, bronze sculptures, etc. The most visible memorial systems, and consequently those requiring the most intensive management, are sculptures, masonry, and lighting system. The nature of the required services is within the abilities of typical maintenance and repair journeymen electricians, plumbers, and other mechanical tradesmen. Illumination is a key architectural aspect of the memorial and, as such, requires constant surveillance to assure all lighting fixtures are functioning properly. All system disruptions and visual blemishes must be addressed in a timely manner to preserve the overall “Exceptional Appearance” of the memorial as envisioned by its designers and expected by the NPS and the public. In addition, an underground Equipment Control Center (ECC) contains circulation pumps, sump pumps, electrical distribution systems, air-conditioning units, water heaters, water treatment system, control systems and a large water cistern. Maintaining these systems requires a preventive maintenance program, a predictive maintenance program and repair capabilities.

The nature of the work required to maintain memorial cleanliness and orderliness are well within the abilities of the typical laborer. Principle duties are keeping the park free of litter, raking the mulched areas to ensure smoothness and desired thickness, removal of trash and debris, polishing metal surfaces, cleaning stone faces, cleaning pavers.

Maintaining an “Exceptional Appearance” condition of the memorial presents the most immediate and continuous contractor objective. The conduct of the contracted workforce must be ever mindful of the significance of the memorial and the sensitivity of visitors and the public while performing the duties within this scope.

MOWING:

Tall Fescue Maryland Avenue Turf Zone measures .55 Acres in total area.

Native Fine Fescue Turf Zone Measures 1.15 Acres in total area.

It is imperative that grass that is stressed from wilt, excess moisture, or other biological factors not be mown until the situation is discussed with the COR. It is best to error on the side of caution. The turf can be mowed at a time determined less stressful. Turf loss due to failure to follow these instructions will be remedied at the expense of the Contractor.

1. Prior to mowing, the contractor shall ensure that the turf area to be mowed are at a proper moisture content, firmness to prevent damage. This can be accomplished with the use of a TDR 350 Field Scout Meter or COR approved equal. COR will provide specific ranges and applications of meter metrics.

2. The Contractor shall inspect/police turf areas prior to mowing for litter and hazards.

3. All mowers shall be equipped with mulching blades and sharpened at a minimum interval of 40 use hours.

4. On the Maryland Turf Panels, it is recommended that zero turn mowers be used. It is also recommended that a cleanup cut is first made and then all turnings be done in the grass as any tire marks left on the hardscape must be removed immediately through pressure washing. The direction of cut will be as follows and then repeated:

i. Long angle left to right

ii. Long angle right to left

iii. 12-6

iv. Block Cut Left to Right long way

v. Block Cut Right to Left long way

5. On the Maryland Turf Panels (.55 acres), the grass shall be maintained at a Height of Cut (HOC) of 3.0-3.5 inches and will be mowed at a frequency needed to accomplish such. The frequency and HOC are best determined through consultations with the COR. Expect a mowing frequency of one to two times a week based upon seasonal conditions.

6. On the Tall Fescue Native Areas, the grass will be mowed once or twice a year, once in Spring and once in Fall decided upon in consultation with the COR, using a mulching bagged push mower set as high as possible. It is imperative that prior to each mowing pass, a person stands up the grass using a plastic fan rake to prevent any possible scalping which Fine Fescue cannot tolerate.

7. In one mowing never remove more than 1/3 of the total leaf blade length to reach the desired HOC. It is best to gradually lower even if this means 3 or more mowing’s in a week. This will be strictly enforced and any damage to the turf environment from failure to follow this guidance will be remediated at the Contractor’s expense.

8. Streaking or uneven cut must be addressed immediately to provide a uniform level of cut.

9. Grass clippings shall be removed or mulched when visible after mowing to leave a neat, clean and uniform appearance.

10. Mowers shall make turns on the turf in a gentle fashion so as not to mark or tear grass.

11. Wheel marks should not be left on hardscape upon completion. If wheel marks are generated, notify COR of situation so that proper methods can be taken to remedy situation at Contractor’s expense.

12. Clippings left behind on turf/hardscape/curb shall be picked up or dispersed.

13. The Contractor shall maintain turf within the results defined in the Performance-Based Matrix.

14. The Contractor shall follow the following safe road transport actions while mowing:

i. Safety Triangle.

ii. Safety Beacon Light on the mower that can be seen from the front and the rear.

iii. Safety vest worn by the operator.

iv. Roll Over Protection System in place.

v. At no time will mower be left unattended with key in ignition.

15. The Contractor shall be responsible for the repair of all damage caused by the contractor to turf or existing infrastructure, for example: hydraulic leaks, damaged mower blade, mudding or tracking, uneven applications of fertilizer or pesticides, etc.

16. The Contractor shall schedule turf cutting so that it does not interfere with Special Events and/or outdoor activities. The contractor will request a copy of permitted mall events from the COR on a bi-weekly basis.

17. Special Events may require adjustment to the turf mowing schedule which the contractor shall honor in coordination with the COR.

TRIMMING:

All areas shall be trimmed concurrent with mowing and involves all grounds.

1. Contractor will be liable for all damage to trees and infrastructure caused by trimming operations.

2. Grass and weeds shall be trimmed around trees, shrubs, buildings, fences, poles, posts, fire hydrants, barriers, boulders, and all other fixed obstacles.

3. Trimming height shall match surrounding area turf heights dependent upon location, Maryland Tall Fescue Zone or Fine Fescue Zones.

4. The Contractor shall maintain turf with the results defined in the Performance-Based Matrix.

EDGING:

Sidewalks, driveways, curbs, and other concrete or asphalt edges located within the Memorial Turf and Tree grounds areas shall be edged at least every two weeks.

1. Edging shall include removal of vegetation from cracks in sidewalks, driveways, and curbs/roadway interfaces within .5 inch of the edged surface

2. The Contractor shall maintain turf and ornamental edges with results defined in the Performance-Based Matrix.

MAINTAIN PLANTING BEDS:

1. Weeding: Eliminate weeds, maintain mulch. All weeds shall be removed or eradicated manually, mechanically or chemically (with COR approved herbicide). All improved grounds should look well-maintained at all times.

2. Mulching: The Contractor shall mulch to standards required in the Performance-Based Matrix. The Contractor shall annually replace all ornamental plant bed mulch, including borders and openings within ground cover beds with COR approved commercial grade shredded hardwood bark mixed with compost ending up with a dark brown color. The Contractor shall replenish/refresh mulch throughout the year as needed to maintain Performance-Based Matrix standards.

i. Unloading mulch onto tarped, containment areas or multiple areas to then distribute around the site is authorized.

3. Pruning: The Contractor shall prune/shear plant life in accordance with ANSI A300 (Part 1)-2008 standards or most up-to-date version. The Contractor shall address incidental or minor pruning issues throughout the year as appropriate and/or necessary to remove any damaged, unhealthy, or unsafe branches. ‘Act of God’ events, site preparation for construction, security line of sight issues, interior canopy thinning for bird control, helicopter damage, and damage done by others are not considered to be incidental.

The Contractor shall prune/shear specific plants and trees (hedges, etc.) in the landscape as horticulturally appropriate to maintain characteristic plant/planting shape, size, location, function, health, and overall plant integrity and aesthetics.

i. Lagerstroemia indica x fauriei ‘Natchez’: The Lagerstroemia should have limited pruning of growing branches and avoid having the top branches cut back. Too much pruning from the top sends suckers shooting from the bottom resulting in additional pruning and unnecessary care. Pruning should happen in early spring before the tree breaks dormancy. There should be consistency across the trees to ensure there are a similar number of main trunks, three (3) being the desired number. Pruning of branches should be done in a manner to expose the trees trunk structure.

ii. Magnolia virginiana: Any necessary pruning should occur after blooming and during the growing season as dormant magnolias do not easily heal. The magnolia has a natural conical shape and should be pruned to this shape. The magnolia should be limbed up over time to allow for pedestrian circulation on adjacent paved surfaces whilst maintaining overall form.

i. The Contractor is responsible for removing epicormics growth (water shoots) from trees throughout the growing season which shall be performed or overseen by an International Society of Arboriculture (ISA) certified arborist. Pruning shall conform to American National Standards Institute (ANSI) A300 pruning standards for maintenance pruning and hazard pruning. ANSI Z-133 and the OSHA CFR29 standards and the industry’s BMP’s (Best Management Practices) shall be met. https://www.osha.gov/laws-regs/regulations/standardnumber/1910 Tree health shall be maintained at an “Exceptional Appearance” level of aesthetics. The arborists tree inspections shall include a record of any conditions which affect the health and/or condition of the tree and recommend corrective treatment for these conditions. Contractor shall gain approval from COR (subject matter expert) before treatment beyond pruning is performed.
