C&O CANAL NATIONAL HISTORICAL PARK

Remove Debris from 6 Aqueducts

Parkwide - 2026 Perform debris, woody plant and vegetation clearance.

Statement of Work

DISCLAIMER: Only the Contracting Officer (CO/KO) can authorize changes in the terms of a contract. The Contracting Officer’s Representative (COR) cannot authorize changes to requirements, payment amounts, or any other provision of the contract (to include subtracting work requirements). The COR acts only within the specific limitations of the CO/KO’s delegation letter.

DISCLAIMER: This document is procurement sensitive and for official use only. All communications shall be executed in accordance with 48 CFR 1.

PART 1: GENERAL

1.1 PROJECT DESCRIPTION:

1. The C&O Canal National Historical Park (CHOH) is home to multiple historic aqueducts used to facilitate maritime transportation activities in the 19th and early 20th century. These aqueducts are historical structures protected by statute and agency policy, and centerpieces of the park’s historical and aesthetic presentation to the American public.

2. The Park’s aqueducts are plagued with unwanted climbing vegetation growth. Climbing vegetation hangs to Aqueduct stone by first softening the stone structures and then attaching themselves to the softened stone. As it grows larger, the attaching limbs also grow bigger. Combined with the produced acids this growth can weaken and create openings in the mortar and stone. Once the root is into the joint, it can crack the stone or brick as the root expands allowing water to get in, ultimately wearing the stone away. This contract is for 12 Base Task, one woody debris removal and one vegetation management for all six Aqueducts. Base Tasks can start upon contract award. You are also bidding on Optional Tasks. These tasks include one additional woody debris removal for all six Aqueducts. The Optional Tasks will not begin until April of 2027. If there is no debris at the Aqueducts by April 2027, the Government reserves the right to push start date to Summer 2027.

3. To prevent premature wear, this project covers debris removal, woody plants and vegetation removal of the six aqueducts identified in Attachment 2 Support Imagery. This includes:

a. Seneca Creek Aqueduct, located at milepost (MP) 22.81 in the town of Poolesville, MD, was constructed in 1832 from locally quarried gleaming red sandstone with a double barrel and a bridged gap design. Seneca Aqueduct spans 112 feet across the Seneca Creek. Seneca Creek is a 5.8-mile stream entirely in Montgomery County, Maryland. It includes two main tributaries, Great Seneca Creek (21.5 miles long) and Little Seneca Creek (14 miles long). The two tributaries merge near Darnestown, then flow to the Potomac under Seneca Aqueduct on the C&O Canal and into the Potomac River. The surrounding topography, with steep slopes, produces rapid runoff and frequent flooding during heavy precipitation events.

b. Monocacy Aqueduct, located at (MP) 42.20 in the town of Dickerson, MD, was constructed between 1825 and 1833 largely of granite with a septuple barrel design. The Monocacy Aqueduct spans 516 feet across the Monocacy River. Together with its fourteen major tributaries the Monocacy River forms a 970-square mile watershed covering parts of Frederick, Carroll and Montgomery Counties in Maryland. Compounding debris accumulation at this site is non-federal logjam clearance of other two bridges up-stream, which sets debris masses in motion that invariably accumulate against the five inner barrels of the aqueduct and as a result obstructs waterflow.

c. Catoctin Creek Aqueduct, located at (MP) 51.53 in the town of Jefferson, MD, was constructed between 1832 and 1834 from granite with a triple barrel design. Catoctin Aqueduct spans 92 feet across the Catoctin Creek. Catoctin Creek is a small secondary stream that flows through northeastern Loudoun County and empties into the Potomac near the Route 15 bridge link between Virginia and Point of Rocks, Maryland. Although small, large debris tends to flow downstream to the aqueduct accumulating along the two outer barrels.

d. Antietam Creek Aqueduct, located at (MP) 69.40 in the town of Sharpsburg, MD, was constructed between 1832 and 1835 from limestone with a triple barrel design. Catoctin Aqueduct spans 92 feet across the Catoctin Creek. This aqueduct has a propensity to accumulate obstructing debris along the two outer barrels due to the shallow depths extending along the banks. The dam effect forces hydrological flow to be diverted through the remaining center barrel. During highwater events, this has the potential to greatly increase the force of flow through the center barrel much like a pressure nozzle on a garden hose. Maryland is currently in Phase II (2018 - 2025) of the Antietam Creek Watershed Restoration plan.

e. Conococheague Aqueduct, located at (MP) 99.80 in the town of Williamsport, MD, was constructed between 1833 and 1835 of limestone with a triple barrel design. The Conococheague Aqueduct spans 196 feet across the Conococheague Creek. The 81 miles of shallow muddy bottom in Conococheague Creek results in accumulation that blocks vessel access to the Potomac River, adversely impacting freshwater maritime traffic in proximity upstream. The overall condition of the structure is a concern, especially given the tendency for invasive vegetation to develop in local masonry seams and joints.

f. Licking Creek Aqueduct, located at (MP) 116.04 in Big Poole, MD, was constructed between 1836 and 1838 of limestone with a single barrel design. Licking Creek Aqueduct spans 96 feet across the Licking Creek. Licking Creek is a 56.6-miles of tributary of the Potomac River in Pennsylvania and Maryland in the United States. Licking Creek is born on the west slope of the Tuscarora Mountain then flows through Fulton and Franklin Counties in Pennsylvania into Washington County Maryland to join the Potomac River downstream from Hancock, MD. Licking Creek’s single arch is historically resistant to major debris and logjams. Partial log jams are beginning to amass.

g. Requirement: The contractor shall provide all labor, supervision, materials, tools, supplies, transportation, barricades, signs, traffic control measures/coordination and equipment incidental to and necessary for wood debris removal, woody plant removal and vegetation management in and around each aqueduct.

4. The park's six aqueducts often flood bi-annually, so this project is for the two Base Tasks plus an Option Task to perform a second Debris Removal each Aqueduct starting 1 April 2027.

1.2 SCOPE OF WORK:

1. BASE TASK 1 - Remove woody debris accumulation at Seneca Creek, Monocacy, Catoctin Creek, Antietam Creek, Conococheague and Licking Creek Aqueduct structures:

a. Remove all accumulated woody debris fields, to include submerged fields, to a submerged depth of four (4) feet or the river/stream bed floor (whichever occurs first). Include all debris within the extent of the debris field upstream/downstream of the façade of the structure or to next structure (Example Catoctin Creek), or within the structure(s) barrels/arches:

* No dredging is authorized. Operations should be designed to minimize river/stream bed disturbance. If soil mixes with woody debris, it is not considered the river/stream bed and should be treated as such for the removal process.

* No chemicals are authorized for use on the structures. Pesticides, no matter if aquatic- safe or not, can impact the integrity of the stone.

*See Attachment 2 Support Imagery for example debris fields.

b. Remove all independent/standalone woody debris three (3) inches in diameter and above, to include submerged debris, to a submerged depth of four (4) feet or the river/stream bed floor (whichever occurs first). Include debris within the predetermined distance of the upstream/downstream façade of the structure, or within the structure(s) barrels/arches.

c. Remove all fine woody intertwined debris within the debris field. This includes twigs and woody debris 2 inches and above.

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

e. Remove all wood and debris in accordance with the technical requirements.

2. BASE TASK 2 - Perform woody plant and vegetation clearance on the Aqueduct, Wing Walls and

Stone Walls. Aqueducts included are the Seneca Creek, Monocacy, Catoctin Creek, Antietam Creek, Conococheague and Licking Creek Aqueduct structures:

a. Utilizing mechanical means and hand tools (i.e., no chemical agents), remove woody plant and other vegetation from the masonry, stonework, seams, crevices, and facades. Includes all on, around, under the structures and four feet of walking clearance around the exterior of the walls and structure.

b. Prune all visibility limiting tree overhang within thirty (30) feet upstream, downstream and around to allow for preventive maintenance.

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

CAVEAT REGARDING DEBRIS ACCUMULATION: Because the aqueducts are positioned in active watersheds, the conditions are dynamic and constantly changing with the rise and fall of water levels. For estimating quotes, anticipate debris accumulation and possibility for flood accumulation during the solicitation and period of performance.

3. OPTIONS (1-6) TASK 1 - Remove woody debris accumulation at Seneca Creek, Monocacy, Catoctin

Creek, Antietam Creek, Conococheague and Licking Creek Aqueduct structures:

STATEMENTS CLARIFYING RESPONSIBILITY:

* The contractor’s work obligation is solely contained in with this Statement of Work and correspondence from the CO/COR. The contractor shall use available support tables, documents, and electronic aids, as well as other resources necessary to locate logjams/ debris, Woody plants and other vegetation in and around the area of responsibility.

* For all tasks the contractor shall take adequate measures to ensure the protection of historic structures on the property (all edifices). The contractor shall perform work while the public use areas of the park remain open to their full and normal uses unless specifically notified in writing that an area will/may be closed. This does not preclude the contractor from securing temporary work zones in accordance with industry best practices and reasonable safety precautions, providing the public thoroughfare is not unreasonably obstructed.

* WEIGHT LIMITS AND LOAD RATINGS: Since the C&O Canal towpath is a historical thoroughfare, it contains many structures such as bridges, waste weirs, culverts, etc. The contractor shall inspect all such structures before crossing them with equipment and vehicles. The contractor shall assess the suitability of each trafficable structure and determine what equipment or vehicles can safely traverse. The contractor is highly encouraged to use bridging and weight dispersion techniques, such as laying timber/steel plates, to facilitate load dispersion when crossing structures. Because weight limits cannot be provided for waste weirs particularly, the contractor shall not leave any vehicle or piece of equipment in a static state on them (maintain motion).

* At no time shall equipment other than personal equipment be stationed on the aqueducts (no vehicles or heavy equipment). Monocacy and Catoctin Aqueducts may be traversed with light vehicles (below F350 type) for the simple purpose of reaching the opposite bank, but vehicles may not be stationed on those structures for work execution.

* GROUND PROTECTION: When appropriate, to prevent damage to soil, vegetation, and surrounding tree root systems, ground protection mats or similar devices are required to be emplaced.

* WORKING IN CONSTRICTED / RESTRICTED SPACES: The area of operations consists of elements of modern and historical infrastructure that may constrict or prevent access of heavy equipment.

It is the solely the responsibility of the contractor to assess the environment and implement methods and means supported by equipment arrays that are suitable to the unique working conditions. The contractor’s methods and means shall not compromise the structural integrity of infrastructure, to include (but not limited to) paved surfaces, bridges, and retaining walls.

* STAGED / STORED EQUIPMENT: The C&O Canal NHP is not responsible for any property the contractor choses to stage on the park during the execution of this task order. The task order does not require any contractor property to be staged. Contractors storing equipment do so at their own discretion while assuming all risk and liability. Equipment storage/staging shall be coordinated with, and approved by, the COR in writing.

* WORKING WITH OVERHEAD AND UNDERGROUND UTILITIES: The area of operations consists of elements of modern and historical utilities that may constrict or prevent work and access of equipment. It is solely the responsibility of the contractor to contact the appropriate agencies, identify and mark (if necessary) all overhead and underground utilities and implement methods that are suitable to these working conditions. The contractor’s methods and means shall not compromise the structural integrity of utilities infrastructure, to include (but not limited to) poles, conduit, paved surfaces, bridges, and retaining walls.

* TRAFFIC CONTROL, SAFETY, AND PEDESTRIANS: The identified work areas represent major thoroughfares with dense pedestrian and cyclist traffic. Furthermore, the C&O Canal towpath represents a major commuter artery for cyclists in the DC Metropolitan region. The contractor shall be responsible for executing the assigned work in a manner that ensures both sustained trafficability and safety for park users.

a. Signage shall be posted at the nearest point on either side of the work zone.

b. Signage shall communicate to the public that delays of up to ten (10) minutes are to be expected. The contractor is not authorized to stop traffic on the towpath for more than ten (10) consecutive minutes before allowing multi-directional passage of pedestrians / cyclists.

c. Work along roadways shall include traffic control measures that conform to US Department of Transportation (US DOT), Federal Highway Administration (FHWA), and CFR 29 requirements, as well as specifications in the Manual on Uniform Traffic Control Devices (MUTCD). It is the sole responsibility of the contractor to take all necessary actions to ensure the safety of all personnel, especially the visiting public, during the execution of operations. The contractor shall follow all federal, state, municipal, and local requirements for permitting and operating along/in roadways.

1.3 ADDITIONAL REQUIRMENT SPECIFICATION(S):
