1 INTRODUCTION

1.1 Purpose

The following are Fort Drum exterior utility design requirements. The purpose of this standard is to insure that the construction of new exterior utilities are compatable with the existing systems on Fort Drum and will function properly when placed into service with the rest of the Fort Drum infrastructure.

2 GENERAL REQUIREMENTS

2.1 The distance between all utilities except water and sewer shall be a minimum of 12”, both vertical and horizontal. Water and Sewer installations shall be in accordance with 10 States

Standards unless deviated from in this document. Duct banks shall be kept separate and shall not be joined with concrete. Utilities shall be run along side the road as much as possible. All existing utilities will be placed on the profiles. The exact depth and location of the existing utilities shall be identified by hand digging after the Excavation Permit is approved. If the utilities cannot be found by hand digging the contractor will notify the appropriate shop for further assistance.

2.2 An excavation is any intrusion into the surface of the earth. This includes, but is not limited to the placement of tent pins, excavation for utility lines, and excavation for foundation elements for outdoor recreational devices, antennas, utilities, and buildings. Fort Drum amends the 16 NYCRR Part 753 definition of excavation as follows: hand excavation, no more than 12 inches into the ground using hand tools, and vacuum excavation, as needed to locate utilities, is allowed without a permit. Unpermitted hand excavation shall stop if utility lines are uncovered.

a. Within the cantonment areas, driving stakes, pins, or rods is not considered hand excavation and requires an excavation permit.

b. In the range area, an excavation permit is required for any intrusion into the surface of the earth on any fixed training facility and along any road out to 50 feet from the road edge.

Units conducting field training exercises (CPX, STX), bivouac, or any field training in a training area will need to submit an excavation permit only for digging operations (i.e.

fighting positions, FOB/COP construction, defensive obstacles, soakage/grey water pits).

Units erecting tents or emplacing ground rods in the training area are not required to submit an excavation permit for areas more than 50’ from the edge of road.

2.3 Utility profile drawings are required for all utility installations.

2.4 CADD asbuilt drawings with GPS coordinates are required for all utility installations.

2.5 Utilities shall not be placed under buildings unless they are the utilities feeding that building.

2.6 Open cutting of roadways is not permitted. All utility installations under roadways shall be installed by directional drilling or boring unless approved on a case-by-case and road-by-road

Revision control of this document is maintained electronically. If printed, individuals are responsible for ensuring basis from PW Engineering prior to commencement of work. Approval of an Excavation Permit is not approval for open cutting of roadways. The specifications and restoration of the roadway will be subject to PW Engineering’s approval. PW Engineering will specify the requirements for roadway restoration. Contractor road restoration plans “to match existing” are not acceptable.

2.7 During the inspection phase of all utilities, the tracer wire will be tested.

2.8 Fuse coordination and arc flash studies shall be done and completed in accordance to

NFPA 70E for every project.

2.9 All generators shall require load banking or at least put in panel switches.

2.10 Fort Drum and New York State operate under the premise of concurrent Federal and State jurisdiction. This means that all of our construction projects must be designed and built "in accordance with all New York State laws and regulations."

2.11 Permits through the NYS DEC and DOH for waste water, water lines, and SWPPPS must be prepared by the designer of record who must be a qualified professional engineer in accordance with NYS regulations. The Director of Public Works will sign the applications as the

"owner/operator" and the designer will submit the complete package to the regulating agency.

2.12 Tracer Wire Access Points

2.12.1 A Tracer Wire Vault (TWABAD J18-18" Tracer Wire Access Box, CP Test Services-

Valvco, Inc.) or equal are required to be placed at each maintenance hole/hand hole to terminate each section of tracer wire. Tracer wire access boxes in unpaved areas shall be installed in a 12” diameter by 8-inch thick concrete collar. Concrete shall have a minimum compressive strength of 4000 psi at 28-days.

2.12.2 Contractor shall provide an assembly that is capable of withstanding AASHTO HS20-44 loading in roads and driveways, all other areas must be durable and appropriate for the area in which the tracer wire box is placed. The unit must be color coded to the utility that the tracer wire is associated with. Tracer wire shall be 12 AWG THHN solid conductor. Any trace wire splices shall be a crimp type connector, with a heat shrinkable cover of the splice.

2.12.3 Tracer wire for communication duct banks shall be installed in ½ inch diameter conduit of similar material to the ducts and installed within the concrete encasement of the duct bank.

2.13 Any request for disruption of utilities, i.e.: turning power, water, sewer, gas off needs to be requested no later than 2 weeks from the requested date to shut off the requested utilities. Any changes of the requested dates shall be brought to the attention of the Public Works Utilities

Department.
