Executive Summary

Fort Wadsworth (Ft. Wadsworth) is a former United States military installation located on the eastern shore of Staten Island at the Narrows of New York Harbor. The fort served as a line of defense for Manhattan and beyond during war times. It is comprised of multiple fortifications, including Fort Tompkins and Battery

Weed. It is currently now part of the Staten Island Unit of Gateway National Recreation Area.

The goal of this project is to renew the water, wastewater, and stormwater utility systems at Ft. Wadsworth.

Each of these utility systems have exceeded their design life. Failure to address the water, wastewater, and stormwater deficiencies would affect the infrastructure reliability and could result in impacts to public and environmental health and safety. To address the systems’ needs, this Program of Requirements (POR) report provides minimum performance requirements for improvements that the Design Build Entity (DBE) selected in the subsequent phase must meet as part of the final design and implementation of improvements. This POR provides information about five elements, which include the water system, wastewater system, stormwater system, temporary works, restoration requirements, and associated information pertaining to compliance and permitting requirements. While general layouts have been provided for guidance, NPS is seeking creative design approaches to create low-maintenance improvements to the existing systems. The DBE shall design to optimize the required improvements. The DBE shall complete an evaluation of the design criteria during detailed programming within the DBE’s contract.

The objective of Project Element 1 is to replace the water system, including service connections, serving the area of Ft. Wadsworth. The length of water pipes, including service connections, is estimated at 31,600’ and water mains range in size from 4” to 12” in diameter. The DBE shall replace the identified water mains, services connections (to building wall), and associated appurtenances present on-site. Project Element 1 outlines standards, technical requirements, and NPS preferences for completion of the water system replacement.

The objective of Project Element 2 is to replace the wastewater (sewer) system, estimated at 11,200’ including service connections and sewer mains ranging in pipe size from 6” to 18” in diameter. The DBE shall replace all sewer mains, sewer service connections (to building wall), and manholes. Project Element

2 outlines standards, technical requirements, and NPS preferences for the completion of the work.

The objective of Project Element 3 is to rehabilitate or replace the existing stormwater (storm drain) system, as identified herein. The total length of the storm system is estimated at 26,100’, including service connections, and ranges in pipe size from 6” to 54” in diameter. The main components of Element 3 include the storm drains, building service connections (to building wall), catch basins, catch basin connections, and manholes. Requirements for the storm drain system include full replacement of assets, spot repair

(replacement), rehabilitation, and storm structure repair work. Project Element 3 outlines standards, technical requirements, and NPS preferences for completion of the storm system work as outlined on project drawings.

The objective of Project Element 4 covers temporary construction activities such as excavation work, bypass/flow management, traffic control/pedestrian safety, site access, tree protection, utility coordination and protection, and temporary stormwater pollution protection. Project Element 4 outlines standards, technical requirements, and NPS preferences for the completion of the work.

vi

The objective of Project Element 5 covers work regarding the restoration of pavement, curbs, sidewalks, grass, and tree plantings. Project Element 5 outlines standards and technical requirements the DBE shall follow for work pertaining to temporary and permanent restorative surface work in areas disturbed by construction activities. Unless otherwise indicated, the DBE shall match the restored surface to the existing surface.

NPS has decided to organize the project work into base bid areas and bid option areas in an effort to complete the most critical work within budget. Base bid will include the replacement of approximately 65% of the water system based on the estimated linear footages, full replacement of the sewer system, and high priority items in the storm system based on the storm infrastructure condition assessments completed as part of this POR. The remaining work items are to be bid as separate options, pending availability of funds.

A preliminary evaluation of the environmental conditions and associated compliance effort has been completed during the POR phase. However, compliance is not complete and the limits of the environmental evaluation is based upon the identified disturbance. During the Design/Build phase of the project, final environmental compliance will be needed prior to the construction Notice to Proceed. This may include the need for additional coordination with external and internal stakeholders and additional clearances as needed for any surveys during detailed design.

This project is within the boundaries of the Ft. Wadsworth Historic District. The DBE shall provide compliance staff who have knowledge of the National Environmental Policy Act (NEPA), National Historic

Preservation Act (NHPA) Section 106, and other environmental compliance laws, NPS policies, and execution of compliance documents; the compliance staff shall be involved in both design and construction phases, as warranted to ensure that compliance issues are taken into account while making decisions and that environmental compliance and permitting is complete prior to initiating work, which could result in impacts to regulated resources. This includes conducting additional surveys as well as construction activities. Table 16 in Section 11.4 outlines anticipated lead times needed for NPS to conclude compliance associated with surveys and field investigations.

The Permit Assessment Form (PAF) has been developed for the base bid project as part of this POR and is provided as a reference within Appendix F. Based on the project limits and project elements defined in this POR, the following permits are anticipated to be required as part of construction for this project:

National Park Service Wastewater Collection System and Wastewater Pump / Lift Station Permits, and

New York City Private Sewer and Water Main Construction Permits. U.S. Environmental Protection

Agency/ U.S. Army Corps of Engineers Clean Water Act Permits and multiple other approvals would be required if project activities extend to the outfalls at New York Harbor.

The DBE will establish a detailed design, compliance and permitting documentation, construction schedule, and budget in alignment with the requirements set forth herein. Deliverable milestones include 50% and

100% Design Build Design Development Documents, 100% Design Build Construction Documents, Complete Stamped and Signed Design Build Construction Documents, and As-Constructed Drawings.

Additionally, the DBE will provide bi-weekly updates to NPS’s Project Manager during design and weekly updates during construction.

1 BACKGROUND

Fort Wadsworth (Ft. Wadsworth), located on the northeastern shore of the Narrows of New York Harbor in Staten Island, New York, is one of the oldest military installations in the nation. The park contains fortifications that were built for protection of New York City for over two centuries. The site remains active for US military and National Park Service (NPS) employees, as well as for visitors to enjoy. Ft. Wadsworth is comprised of National Register Historic Districts and contains critical cultural resources.

Archaeological and historical accounts document Staten Island and the immediate area of Ft. Wadsworth was inhabited by native populations as early as 10,000 – 12,000 years ago during the Paleoindian period up until contact with Europeans. After multiple failed attempts, the first sustained European colony of

Oude Dorp was established south of Ft. Wadsworth on Staten Island. After gaining control of the region, British forces began using Staten Island as a staging area during the Revolutionary War in 1776. The

Narrows provided a strategic location for defense and military development and use continued through historic times having served as state and federal military reservations by various agencies. The area that eventually became Ft. Wadsworth was later transferred to NPS in 1995 as part of the Gateway National

Recreational Area. Over the next few decades, the US Coast Guard and US Army Reserve occupied several buildings within Ft. Wadsworth and still do to this day.

This document is the Program of Requirements (POR) to rehabilitate the water, wastewater, and stormwater utility systems at Ft. Wadsworth. The project is known by NPS as N111 GATE 318738. The project boundary was identified by NPS and is shown in Figure 1. The project covers the majority of the

Ft. Wadsworth property, namely all areas where NPS is responsible for maintaining the utilities. The area shown in Figure 1 as maintained by the Metropolitan Transportation Authority (MTA) is not included in the project area.

The original utility systems at Ft. Wadsworth (northwest section) were constructed during the 1920s

(water and wastewater) and portions of the storm system in the 1970s, per available record plans. Most of the original systems are still in place with only limited rehabilitation or repair over the years on specific components, and all of these utilities have exceeded their design life.

Figure 1: Project Boundary (Excludes MTA Maintained Area)

1.1 PROJECT ANALYSIS

The goal of this project is to design and construct the rehabilitation of the water, sewer, and storm systems at Ft. Wadsworth based on the existing age of the systems. This POR encompasses elements 1 through 5 that provide information about the water system, wastewater (sewer) system, stormwater

(storm drain) system, temporary works, and restoration requirements. This is followed by information pertaining to permitting and compliance requirements. While general layouts have been provided for guidance, NPS is seeking creative design approaches to create low-maintenance improvements to the existing systems.

The occupied buildings and cultural resources on the site that require water service for fire protection and/or domestic use. NPS has decided that a complete replacement of the water system is required based on the age of the system. The components include the water mains, service connections, fittings, valves, meters, and fire hydrants.

Any occupied buildings with domestic water use or floor drains require wastewater service. NPS has decided that a complete replacement of the wastewater (sewer) system is required based on the age of the system and the maintenance issues that NPS has experienced. The main components include the sewer mains, service connections, and manholes.

It is understood that the existing stormwater (storm drain) system provides adequate drainage of building roofs and roadways. These assets have generally been inspected for defects by visual inspection to recommend where rehabilitation, replacement, or no action is required. The main components include the storm drains, building service connections, catch basins, catch basin service connections, and manholes.

Failure to address the water, wastewater, and stormwater deficiencies would affect the infrastructure reliability and could result in impacts to public and environmental health and safety.

In addition to the engineering needs, this POR has reviewed and assessed the environmental and cultural considerations for the improvements. This review has established the compliance and permitting needs based on a general understanding of the implementation of the project and sought to identify changes that would trigger additional compliance or permitting needs. Compliance is required in accordance with federal programs, such as the National Environmental Policy Act (NEPA), the National Historic

Preservation Act of 1966, as amended (NHPA), and the Archaeological Resource Protection Act of 1979

(ARPA).

See each Project Element for the specific minimum program analysis requirements. This POR is provided for guidance only. The Design-Build Entity (DBE) shall design to optimize the required improvements. The

DBE shall complete an evaluation of the design criteria during detailed programming within the DBE’s contract.

1.2 PROGRAM ANALYSIS

See each Project Element for the specific minimum program analysis requirements. This POR is provided for guidance only. The Design-Build Entity (DBE) shall design to optimize the required improvements. The

DBE shall complete an evaluation of the design criteria during detailed programming within the DBE’s contract.

1.3 EXISTING DOCUMENTATION

The existing utility locations are shown on Drawings in Appendix A, which were prepared using information from field investigations and records. Site investigations included visual observations, aerial photography and survey, topographic survey, utility survey, closed-circuit television (CCTV) inspection data of storm system infrastructure as provided in Appendix B, and soil borings as provided in Appendix

C. Record drawings were used to confirm field information where they were available. Approximations were made in the case where existing information conflicted or was not available. The General Notes in the Drawings in Appendix A detail limitations to existing information and callouts on the plan sheets identify locations where the DBE must investigate or confirm specific items, such as utility connectivity or active status. A survey file, available record drawings, and the video files from the CCTV inspections of the storm system will be provided to the selected bidder.

Natural and cultural resource information for the project area has been reviewed to identify the requirements of this POR. Cultural resource documents are provided in Appendix G. Additional reports and documentation are available at the request of NPS. Natural and cultural resources are further described in Sections 10 through 12 of this POR.

Contracting Officer (CO): Tony Jasper, 303-969-2789, tony_jasper@nps.gov

1.5 IMPLEMENTATION STRATEGY

The delivery model for this project is expected to be Best Value Design-Build/Fixed Price procurement.

This requires the DBE to provide a price and technical proposal for the improvements. The technical proposal shall include the scope of services for design by licensed engineering and environmental professionals in the State of New York.

All standard practices for design and construction shall comply with requirements of federal projects as outlined by the NPS Denver Service Center (DSC) at the following site:

https://www.nps.gov/orgs/1804/dscdandc.htm.

The DBE shall conduct bi-weekly progress update meetings to the NPS project team from the time of design Notice to Proceed through delivery of the Construction Documents. The DBE shall conduct weekly progress update meetings to the NPS team from construction Notice to Proceed through to final completion. The DBE is required to prepare the agendas, the minutes, and lead these meetings.

The DBE shall coordinate with NPS to identify temporary needs during construction, as all locations to satisfy temporary needs shall be approved by NPS prior to implementation. Such needs may include, but not be limited to, access routes, vehicular and pedestrian traffic management, storage, staging, and stockpile (refuse and demolition materials included) locations. These shall be stated during the design process for review and approval by NPS. If additional storage, staging, and stockpile areas are required beyond that allowed by NPS, the DBE shall locate and maintain an off-site location(s) at no additional cost to NPS. The DBE shall not assume that temporary utility hook-ups to support construction will be allowed, including for water, electric, and communications.

The DBE is responsible for preparing and providing to NPS information and project documents required for legally mandated compliance processes to protect environmental and cultural resources. Compliance is required for any survey or field investigation work during design as well as for the final construction project, as further discussed in later sections. Coordination with the compliance team should be initiated as soon as possible to determine data needs and compliance schedules to minimize impacts on the design and construction schedules. No work at the site shall begin prior to receiving compliance approvals. Construction Notice to Proceed (NTP) will not be issued until compliance is completed for both design and construction. NPS is committed to providing collaborative assistance throughout the compliance process.

In addition, the DBE is responsible for determining applicable permits and obtaining them before the start of any work at the site.

This POR document outlines the requirements to be followed in order to complete the project. If any conflicts between this POR document and the Division 01 specifications, the POR shall take precedence.

4 PROJECT ELEMENT 1 – REPLACE WATER SYSTEM

Ft. Wadsworth has approximately 31,600’ of water pipes, including service connections. The water mains range in size from 4” to 12” in diameter, and the primary material is assumed to be cast iron based on records but it is likely other materials are present. The service connections are in most cases unknown size and material. The site also contains approximately 46 fire hydrants.

The water is supplied to the site by NYCDEP. Ft. Wadsworth receives water from NYCDEP at two 8” city water meter and valve pits: one is located on the north side of the site at New York Avenue and North

Road and the other is located on the southwest side of the site, on McClean Avenue at Lily Pond Avenue.

NPS has decided that due to the age of the infrastructure, the water system is in need of repair. The scope of the water system replacement will be identified by geographical areas, as discussed in Section

9. Within each area, the DBE is expected to perform complete replacements of the water system. The components include the water mains, service connections, fittings, valves, meters, and fire hydrants.

The DBE should explore alternatives to current system layout. The following criteria must be met:

Connections to NYCDEP’s system remain at the same location.

Service is provided to all required buildings.

Hydrants are properly spaced to provide fire protection.

Adequate capacity is provided to convey anticipated flows, including fire flow requirements.

4.3 The DBE should analyze construction methods for the

replacement of the water system that are efficient and minimize potential impacts to the project area, including recently paved roadways, trees, and the historical landscape. The DBE can consider relocation of existing water mains or utilizing the same trench for replacement. Same trench replacement includes removal and disposal of existing water mains, and relocation includes abandonment of existing water mains in-place per Section 4.10UTILITY CROSSINGS

Per Ten State Standards, new sewer mains shall be installed below water mains and shall have a minimum of 10’ horizontal separation and 18” vertical separation measured between the edge of pipes or structures. If minimum separations cannot be met, take precautions in accordance with the Ten State

Standards. Per NYC Plumbing Code 2022 603.2, water service connections and sewer or storm drain service connections shall have a minimum of 5’ horizontal separation and 12” vertical separation if feasible. Clearances from other utilities shall meet owner’s requirements, or a 5’ horizontal separation and

12” vertical separation measured between the outside edge of pipes or structures where possible. If minimum separations cannot be met, the DBE shall identify these locations on the design drawings.

ABANDONMENT. Where relocation is required outside of the existing utility corridor, the DBE shall provide justification for the proposed deviation. Bypass and shutdown requirements are provided in

Section 7.2.

Minimum water main size shall be 8” in diameter but 6” diameter pipes may be used for branches to hydrants. Water main dead ends should be minimized to the extent possible and hydrants should be installed at any dead ends to allow for flushing.

Pipe bedding and backfill to be determined based on soil conditions and manufacturer’s recommendations.

The new water mains shall be pressure tested per AWWA C600, disinfected per AWWA C651, and dechlorinated per AWWA C655 prior to being placed into service. Chlorination injection points and blow off assemblies are required for disinfection.

4.4 WATER SERVICE CONNECTIONS

Water services are to be provided to all occupied buildings. There are 40 buildings that require a water service, and the number of water service connections for each building are shown on the Drawings in

Appendix A. It is assumed that the DBE is to replace all existing water services to the building wall unless outside the project boundary. The DBE can consider utilizing the same trench for replacement or relocation of existing water service connections. The number of service connections and the existing service connection locations at the building wall shall be maintained, as work within buildings is not included in the scope of the project. Same trench replacement includes removal, and disposal of existing water service connections and relocation includes abandonment of existing water service connections in-place per Section 4.10.

Water service connections shall be replaced with the same size or larger than existing. Domestic service connections shall be a minimum of 1” in diameter for a single domestic water connection, a minimum of 1-

1/2” in diameter for connections to duplexes, and 4” in diameter for fire connections. Where meters are not installed, curb stops or shut-off valves should be installed outside of roadway travel limits within sidewalks or walkways where possible.

Water service connections that are 2” and smaller shall be Type K copper per ASTM B88 and installed per AWWA C800. Larger water service connections (4” and larger) shall be ductile iron and follow the requirements in Section 4.2. Connections to the existing water service connections shall be designed to accommodate the condition and material of the existing water service connections.

Pipe bedding and backfill to be determined based on soil conditions and manufacturer’s recommendations.

4.5 WATER FITTINGS

The locations and types of fittings, such as bends, tees, and crosses are to be determined by the DBE based on the proposed water main alignment.

Ductile iron fittings for water mains and 4” and larger water service connections shall be in accordance with ANSI/AWWA C110/A21.10. Joint connecting hardware shall comply with C 111/A21.11. The fittings shall be rated for the depth of cover and anticipated pressures.

4.7 WATER METERS

The existing 8” water meter at the connection to NYCDEP’s system, located on the north side of the site at New York Avenue and North Road, shall be replaced. A backflow preventer shall also be replaced in accordance with NYCDEP’s requirements. The existing 8” water meter located on the southwest side of the site, on McClean Avenue at Lily Pond Avenue is out of scope.

Additional water meters on the water system should be installed, at minimum, to meter the following areas:

The fenced US Coast Guard area between Coast Guard Drive and Drum Road west of New York

Avenue, The US Coast Guard housing area south of project boundary that are fed by water mains on USS

Tennessee Road and USS New Mexico Court.

The United States Army Reserve Center on the south side of Drum Road west of New York

Avenue.

The United Stated Army Reserve Center on the north side of Battery Road west of New York

Avenue.

Unless otherwise directed by NPS, each service connection (for buildings not listed above) behind the curb (in grass or sidewalk) per NPS Staff Directive 78-10.

DBE to assess exact locations for these water meters to balance accessibility for meter readings with the limitations to looping the water system and reducing capacity for fire flow.

Water meters should be selected and installed in accordance with AWWA Manual M6.

4.9 UTILITY CROSSINGS

Per Ten State Standards, new water mains shall be installed above the sewer and shall have a minimum of 10’ horizontal separation and 18” vertical separation from sewer measured between the edge of pipes or structures. If minimum separations cannot be met, take precautions in accordance with the Ten State

Standards. Per NYC Plumbing Code 2022 603.2, water service connections and sewer or storm service connections shall have a minimum of 5’ horizontal separation and 12” vertical separation if feasible.

Clearances from other utilities shall meet owner’s requirements, or a 5’ horizontal separation and 12” vertical separation measured between the edge of pipes or structures where possible. If minimum separations cannot be met, the DBE shall identify these locations on the design drawings.

4.10 ABANDONMENT

There are several buildings which are known to be previously demolished. Any service connections not currently connected to a building or other infrastructure shall be capped at the limits of the excavation for the new water main. The DBE to perform testing to confirm connectivity and verify with NPS before proceeding with abandonment of service connections.

Additionally, there are locations where changes to the water system have left capped spurs. Once it is confirmed that they are not currently connected to a building or other infrastructure, they are not to be replaced and shall be abandoned in-place along with any associated water service connections. Known locations have been identified in the Drawings in Appendix A for further investigation, but additional locations shall be anticipated. The DBE to verify with NPS before proceeding with abandonment work.

The ends of all abandoned pipes shall be capped or plugged. Abandoned pipes 12” in diameter or greater shall be filled with controlled low strength material, such as grout, as pipes will continue to degrade over time and potentially collapse causing disturbances at the finished grade.

For abandoned valves or water manholes, the asset shall be removed to a minimum of 3’ below grade, filled with a controlled low strength material, such as grout, and pavement restored to match existing grade. No cover or other surface features should remain visible.

5 PROJECT ELEMENT 2 – REPLACE WASTEWATER (SEWER)

SYSTEM

There are approximately 11,200’ of gravity sewer pipes, including service connections. The sewer mains range in size from 6” to 18” in diameter, though some of the service connections may be smaller. The pipe materials include vitrified clay pipe (VCP), polyvinyl chloride (PVC), and cast iron, but it is likely that other materials are present. The manholes vary in size and are either constructed of concrete or brick.

There are approximately 72 existing manholes on the site. On the southwest area of the site, the United

States Coast Guard housing area is serviced by a pumping station and force main; these components are not included in the scope of work.

The on-site wastewater (sewer) system drains into NYCDEP’s system and discharges must meet the sewer use by-law. The systems connect at 3 locations: on the north side of the site at New York Avenue, on the northwest side of the site on Coast Guard Drive, and on the southwest side of the site on McClean

Avenue. Sewers north of the Verrazzano-Narrows Bridge flow to the Port Richmond Wastewater

Treatment Plant and sewers south of the bridge flow to the Oakwood Beach Wastewater Treatment Plant.

NPS has decided that a complete replacement of the sewer system is required based on the age of the system and maintenance issues experienced. The main components include the sewer mains, service connections, and manholes.

It was assumed that the size of the sewer system will generally be replaced in-kind; however, the DBE may explore alternatives to the current system layout if the following criteria are met:

Connections to NYCDEP’s system remain at the same location.

Service is provided to all required buildings.

Adequate capacity is provided to convey anticipated flows.

Adequate, positive slopes are provided to achieve flushing velocities.

In order to validate a new system layout, the DBE…
