Performance Work Statement (PWS)

I. Description Of Work

1. Performance Work Statement. The Chesapeake & Ohio Canal National Historical Park (CHOH) is in need of turf management services in identified areas of the park’s Palisades Maintenance District.

CHOH is responsible for the care and upkeep of the C&O Canal. The Palisades Maintenance District of the C&O Canal has a very high public exposure, as it stretches from Potomac, MD to Georgetown in Washington, DC. This location is often used for recreational and commuter bicycling, hiking, and walking. Turf management services are required to maintain the area for public use. All work is located within the CHOH Palisades Maintenance District.

The contractor shall provide all labor, supervision, materials, tools, supplies, transportation, barricades, signs, and equipment incidental to and necessary to execute mowing services required with-in the boundaries of the C&O Canal National Historical Park.

In addition, the contractor shall comply with the CHOH Superintendent’s Compendium and all Amendments which can be found at: Superintendent's Compendium - Chesapeake & Ohio Canal National Historical Park (U.S. National Park Service) (nps.gov)

1) TASK 1: Maintain turf management in areas identified in the Enclosure 1 attachment.

a. Maintain turf height in a range of three (3) to six (6) inches for all areas excluding canal prism locations and locks.

b. Remediate any ground damage incurred during the performance of operations (e.g. ruts, holes, etc. )

c. c. Perform string trimming around curbs, structures (historical and non-historical), infrastructure, and landscape features.

2) TASK 2: Maintain turf management along the C&O Canal Towpath and Capital Crescent Trail (CCT) from Potomac Street SW to Mile Post 15.

a. Turf height shall be in a range of three (3) to twelve (12) inches. Width of management area shall range from twenty-four (24) to thirty-six (36) inches off shoulders as terrain allows. The contractor is authorized to cut up to 60 inches off the shoulder where it is conducive to efficient operations.

b. Remediate any ground damage incurred during the performance of operations (e.g. ruts, holes, etc.)

c. Turf management of the CCT terminates at Mile Post 3.6 where the Arizona Avenue Bridge (steel bridge) crosses over the canal prism and exits the park boundaries.

3) TASK 3: Maintain turf management in areas identified in Enclosure 1A, Fletcher’s Cove and Abner Cloud House area.

a. Maintain turf height in a range of three (3) to six (6) inches for all areas excluding canal prism locations and locks.

b. Remediate any ground damage incurred during the performance of operations (e.g. ruts, holes, etc. )

c. Perform string trimming around curbs, structures (historical and non-historical), infrastructure, and landscape features.

4) The required number of services is estimated by the government as 15-25 visits per year on a 7-10 day schedule. This is a firm-fixed price contract – the exact number of cuts required will be dependent upon seasonal conditions such as weather and will not be subject to compensation for https://cms.nps.gov/choh/learn/management/superintendent-s-compendium.htm https://cms.nps.gov/choh/learn/management/superintendent-s-compendium.htm sloftus Highlight sloftus Highlight

5) Manpower and equipment shall be capable of completing an entire mowing and trimming cycle for the park within 2 (two) working days. Therefore, any items not specifically noted, but necessary for performance in accordance with industry standards and the specifications stated herein, shall be furnished under this contract. Note: The NPS estimates the production for Mowing and Line Trimming based on past experience as follows:

Mowing:

60-inch walk behind 1 acre/hour 7-8 acres/day 72-inch riding mower (1.5-2 mph) 2-2.5 acres/hour 16-20 acres/day 80-inch tractor pulled (3-4 mph) 2-3 acres/hour 16-24 acres/day 121-inch 455D riding mower (2-3 mph) 2.5-4 acres/hour 20-32 acres/day 192-inch 580D riding mower (2-3 mph) 4.5-6 acres/hour 36-48 acres/day Line trimming/edging: 3,000-4,000 linear feet per day/man

6) It is recommended that the Contractor attend the scheduled site visit to inspect the site to verify the estimated quantities provided by the NPS and the complexities of conducting turf maintenance activities in areas containing high densities of vehicles, pedestrians, and structures. This is considered to be a standard requirement for developing, implementing and executing efficient, cost-effective turf maintenance support services.

Method Defined

8 | P a g e

Random Sampling

The COR randomly inspects work and provides a record of inspection to stakeholders denoting work quality and any deficiencies. A random inspection may encompass the entirety of work specification or a sample area.

Scheduled Inspection

The COR schedules a work site inspection with the contractor and conducts a walk-through and review. The contractor may chose to send a representative in order to receive immediate performance feedback. A record if inspection is generated detailing work quality and any deficiencies. A scheduled inspection may encompass the entirety of work specification or a sample area. Close out inspections for payment are generally scheduled inspections.

Customer Input

This is a supplemental method used by the COR to target inspection areas, provide valuable feedback to the contractor, and augment information provided in quality assurance records as substantiating evidence. Customer complaints may be received by the COR from NPS staff working and impacted in the service areas or members of the public.

VI. Invoicing and Payment

14 | P a g e

1. Invoicing and payment must be broken down into two separate line items.

The first line item shall include the following locations: Areas identified on page 7 of Enclosure 1 - Fletchers Cove and Abner Cloud House locations as identified in Task 3 of this Performance Work Statement. These items must be applied to the specific Fletcher’s Cove funding account. The second line item shall include the remainder of sites in Enclosure 1, and the contractor shall invoice these to the general mowing fund.

2. All invoicing is based on the completion of a full cycle. The invoice shall receive appropriate payment action based on the contractor’s completion of the service in accordance with the requirements (see PARA 2.1.2). The contractor shall estimate the number of cycles required through-out the period of performance based on the contractor’s independent judgement and calculations and divide the estimated number of cycles by the overall task order award amount in order to ascertain the cycle invoice amount. A total of fifteen percent (15%) of the total contract award amount shall be ineligible for invoicing and billing until the end of the period of performance. Because this is a firm fixed price contract, the contractor is responsible for execution throughout the period of performance, without additional compensation beyond the original award amount.

3. The contractor shall provide a notification when a mowing cycle is complete. The COR will inspect the work on-site in consultation with other NPS staff members. The close-out inspection shall be documented in writing, and must clearly convey any deficiencies and remedial action required. In the event that the work is not acceptable, the contractor shall record a list of items noted by the Government to be corrected. A subsequent inspection may take place in order to review the corrected items.

4. Invoices submitted without a close-out inspection shall be rejected, therefore it is imperative that the contractor notify the COR when a mowing cycle is complete.

5. The Contractor shall submit all invoices through www.ipp.gov within 30 days of work performed.

Failure of the contractor to upload an attached copy of the invoice and any requested documentation through IPP.gov will result in invoice being rejected. This is the only authorized invoicing mechanism.
