1.2 Contractor Personnel

1.2.1 Project Manager

The contractor shall provide a project manager who shall be responsible for the performance of the work. The name of this person, and an alternate or alternates, who shall act for the contractor when the manager is absent, must be designated in writing to the contracting officer.

1.2.1.1 The project manager or alternate must have full authority to act for the contractor on all contract matters relating to daily operation of this contract.

1.2.1.2 The project manager or alternate must be available during normal work hours to meet in the park with government personnel (designated by the contracting officer) to discuss problem areas.

1.2.2 Employee Training

The contractor shall ensure that employees performing tree work are fully trained to current arboricultural industry standards for each task they undertake. Contractor employees engaged in felling, topping, climbing, and rigging of trees must have current International Society of Arboriculture, Tree Care Industry Association, or equivalent professional certification in those activities before starting work under this contract. Contractor employees operating winches, power tools and heavy machinery must be fully trained and proficient in the use of this equipment.

1.3 Commencement

Period of performance shall end on December 31, 2023. Because the performance of tree work must be coordinated with NPS personnel providing debris cleanup support, the contractor shall provide the COR with a site-by-site task completion schedule at least 10 business days prior to the start of work. These dates will be agreed upon between the NPS and the contractor. The contractor is expected to adhere to this schedule, excepting for postponement and subsequent rescheduling of work activities due to inclement conditions described in section 1.5. Work conducted in the Longmire Area and Nisqually Entrance including any modifications, shall be completed by December 31, 2023.

1.4 Hours of Operation

All work performed under this contract shall occur during daylight hours, Monday through Thursday. No work shall be allowed on Saturdays, Sundays, and federal holidays.

1.5 Working Conditions

Felling and topping of trees shall not be performed in wind conditions that will interfere with the faller’s ability to control the direction of a tree’s fall. No work activities under this contract shall be performed in sustained winds greater than 25 mph, in whiteout conditions, in an area under active flood warning, or when snow depth or avalanche conditions prohibit safe access to the work site.

1.6 Safety

1.6.1 All operations under this contract shall be conducted in accordance with ANSI Z133.1-2006 Tree Care

Safety Standards, and all federal OSHA, state and local safety requirements. Where OSHA regulations and

ANSI standards conflict, OSHA regulations will take precedence.

DEFINITIONS

2.1 General Definitions

2.1.1 Deficient Service

A service output that does not meet the standard of performance requirement specified in the contract for that service.

2.1.2 Performance Requirements Summary

A listing of the service outputs under the contract that are to be evaluated by the COR or designated park representative on a regular basis, the surveillance methods to be used for these outputs, and the performance requirements of the listed outputs.

2.1.3 Quality Assurance

A planned and systematic pattern of all government actions necessary to provide confidence that adequate technical requirements are established; products and services conform to established technical requirements;

and satisfactory performance is achieved. Quality assurance refers to actions by the government assurance functions for a contracted service.

2.1.4 Quality Control

Those actions taken by a contractor to control the production of outputs to ensure that they conform to the contract requirements.

2.2 Technical Definitions

2.2.1 DBH (Diameter at Breast Height)

A tree stem’s width at a height of at 1.4 m (4.6 ft.) above the ground; on sloped ground, this reference point is applied to the uphill side of the stem.

2.2.2 Debris (also: treatment debris, woody debris)

Includes all downed material resulting from hazard tree treatments, both felling and topping: limbs, twigs, foliage, bark, fragmented pieces of a tree, and logs.

2.2.3 Fell

To remove most or all of the vertical structure of a tree, leaving a flush-cut stump.

2.2.4 Flush-cut

To cut a stump as close as possible to mineral soil following the slope angle of the ground (taking into account stumps not on flat ground). This may require raking back the mulch/litter layer to allow for a lower cut and then raking the material back up against the stump. To hasten the process of decomposition, the top of stump shall be scored to allow better penetration of water. Trees less than 36 inches DBH shall be cut to a 1-3 inch above-soil height. Trees that are 36 inches DBH or greater may be cut to a 6-inch above-soil height.

2.2.5 Naturalize

To create features on the stump of a topped tree which facilitate wood decomposition and use of the stump as habitat by bird and mammal species. This entails at least one bark slit that separates a 1-3’ section of the bark from the stump and one borehole into the heartwood of the stump. These features, when prescribed, are an addition to the jagged top treatment applied to every topped stump.

2.2.6 Top

To remove the upper portion of a tree, leaving a standing snag or tree at least 10 feet in height. In the case of live trees from which only the dead portion of the canopy is removed, the final top cut shall be smooth and angled to allow water to run off. For all other topped trees, the top of the stump shall be cut asymmetrically and scored to make it appear jagged, as though a natural stem breakage occurred.

2.2.7 Treat

Physical alteration of a tree to either 1) mitigate the hazard it presents to persons and facilities, or 2) manipulate the appearance of the cut end of a topped tree or high stump.

2.2.8 Tree Work

Topping, felling, limbing, climbing and rigging, and other treatment activities.

CONTRACTOR-FURNISHED ITEMS AND SERVICES

4.1 General Information

Except for those items or services specifically stated in section 3 as government furnished, the contractor must furnish everything needed to perform this contract according to all its terms.

SPECIFIC TASKS

5.1 General Information

The contractor must provide all personnel, equipment, tools, materials, supervision, and other items necessary to fell or top designated hazard trees and treat stumps as specified in this performance work statement. The contractor must perform to the standards in this contract.

5.2 Fell Designated Hazard Trees

The contractor shall fell all trees for which this type of treatment is specified. Felling involves removing all of a tree’s vertical structure, leaving a flush-cut stump.

5.2.1 Trees shall be felled in a manner that causes no damage to tables, benches, signs, waste or recycling receptacles, vehicles, structures, roads, above-ground and subsurface utilities, or to any government, concessionaire or visitor property, and no injury to persons.

5.2.1.1 The contractor shall move tables, benches, signs, and waste/recycling receptacles out of the target area for a tree to be felled, if necessary to prevent damage to the items. With permission from the

COR, project inspector, or other designated park representative, the contractor may disassemble these items to the extent necessary for their movement, and without damage to or breakage of the items. Any items that are disassembled or moved shall be reassembled by the contractor and put back in place after the felling is completed. The contractor shall furnish tools and equipment for this purpose.

5.2.2 Trees may be felled by any means other than those involving explosives (park policy does not permit the use of explosives by non-government personnel).

5.2.3 Trees designated for felling shall be flush-cut to the specifications described in 2.2.4. The only exceptions shall be negotiated on a tree by tree basis during the pre-bid site tour.

5.2.4 The contractor shall clear any debris from felled trees to maintain the accessibility and functionality of public spaces within the project area. It is crucial that all debris generated from the removal of hazard trees be promptly cleared to prevent any potential hazards or disruptions to pedestrian and vehicular traffic, parking facilities, and common areas. Clearing debris involves moving it to a location that does not impede pedestrian and vehicular traffic, parking facilities, and common areas by way of hand or machinery.

5.2.4.1 Removal Plan: Develop a comprehensive removal plan that includes provisions for debris management. This plan should outline the methods, equipment, and personnel necessary to promptly and safely remove any debris that could impede roadways, parking spaces, or common areas.

5.2.4.2 Immediate Clearing: Upon successfully removing a hazard tree, you must ensure that all resulting debris is promptly moved out of the way, allowing unimpeded access to roadways, parking spaces, and common areas. Promptness is critical to minimize any inconvenience or safety hazards to the public.

5.3 Top Designated Hazard Trees

The contractor shall top all trees for which this type of treatment is specified. Topping involves reducing the height of a tree to a point at which it cannot deposit branches or trunk sections (its own or those of another tree through impact) onto frequently or intermittently occupied targets. The objective of topping is to leave a high stump or short snag that will serve as wildlife habitat and provide aesthetic vertical structure without presenting a risk for harm to facilities or property.

5.3.1 Trees shall be topped in a manner that causes no damage to tables, benches, signs, waste or recycling receptacles, vehicles, structures, roads, above-ground and subsurface utilities, or to any government, concessionaire or visitor property, and no injury to persons.

5.3.1.1 The contractor shall move tables, benches, signs, and waste/recycling receptacles out of the target area for a tree to be felled, if necessary to prevent damage to the items. With permission from the

COR, project inspector, or other designated park representative, the contractor may disassemble these items to the extent necessary for their movement, and without damage to or breakage of the items. The contractor shall furnish tools and equipment for this purpose.

5.3.2 Trees may be topped by any means other than those involving explosives (park policy does not permit the use of explosives by non-government personnel). Some trees may require a lift truck to access the required cutting height.

5.3.3 A tree designated for topping that is within striking distance of administrative, concessionaire or visitor facilities (buildings, utility structures, bridges, parking lots, information kiosks, roadside parking pullouts) shall be shortened to the extent that removes these facilities from target range as the remaining stump or snag decays and fragments.

5.3.4 A tree designated for topping that is within or immediately adjacent to campsites will be shortened to a height no greater than 15 feet and no less than 10 feet.

5.3.5 The final cut end of every topped tree shall be treated as described in section 2.2.6, and as shown in

Technical Exhibit 6 – Quality Standards. Specific topped trees, identified in Technical Exhibit 3, shall also be naturalized as described in section 2.2.5.

5.3.6 The contractor shall clear any debris from top designated hazard trees to maintain the accessibility and functionality of public spaces within the project area. It is crucial that all debris generated from the removal of hazard trees be promptly cleared to prevent any potential hazards or disruptions to pedestrian and vehicular traffic, parking facilities, and common areas. Clearing debris involves moving it to a location that does not impede pedestrian and vehicular traffic, parking facilities, and common areas by way of hand or machinery.

5.3.6.1 Removal Plan: Develop a comprehensive removal plan that includes provisions for debris management. This plan should outline the methods, equipment, and personnel necessary to promptly and safely remove any debris that could impede roadways, parking spaces, or common areas.

5.3.6.2 Immediate Clearing: Upon successfully removing a hazard tree, you must ensure that all resulting debris is promptly moved out of the way, allowing unimpeded access to roadways, parking spaces, and common areas. Promptness is critical to minimize any inconvenience or safety hazards to the public.

5.4 Flush-cut or Treat/Naturalize Stumps from Past Treatments

The contractor shall flush-cut or treat/naturalize designated stumps of previously felled or topped trees.

5.4.1 Stumps of previously felled trees shall be flush-cut to the specifications described in section 2.2.4.

5.4.2 Stumps of previously topped trees that were not sufficiently cut and scored to resemble a jagged natural stem breakage, as illustrated in Technical Exhibit 6, shall have this treatment applied, and will be naturalized to the specifications described in section 2.2.5.

5.4.3 Stumps shall be flush-cut or treated/naturalized in a manner that causes no damage to tables, benches, signs, waste or recycling receptacles, vehicles, structures, roads, above-ground and subsurface utilities, or to any government, concessionaire or visitor property, and no injury to persons.
