BUILDING 14 SEWER LINE CHECK VALVE

SCOPE OF WORK

1.0 Objective

The objective of this project is to perform all requirements to excavate manhole near Building 14 and install check valve in the sewer line at VA New York Harbor Healthcare System – Brooklyn Campus.

2.0 Scope of Work

2.1 General

A. The contractor shall be responsible for all labor, materials, equipment, disposal, and supervision required to perform the work as indicated the scope of work, specifications and drawings. All work shall be performed at the Veteran’s Affairs Medical Center Brooklyn Campus located at, 800 Poly Place, Brooklyn, New York NY 11209.

B. The contractor shall excavate manhole near Building 14, install new Flood Gate Automatic Backwater Valve or equal (See Attachment 1 and 2) in the sewer line so that it is isolated from Building 2 sewer which is necessary due to repeated flooding that has put the regional computer system at risk. Contractor shall install new standard approved NYC DEP sewer line manhole (See Attachment 3) and in accordance with Sewer Precast Manhole Specification (See Attachment 4). Contractor shall install approximately 10 yards of 6-inch pipe. Contractor shall repair sidewalk and road and restore area to original site conditions. Contractor shall provide engineering and drawings, utilities survey and demarcation.

C. The majority of the work is to be performed during normal business hours, however off hour work may be required in order to minimize impact to services provided by the facility and will be at the COR’s discretion and approval. Normal working hours are Monday through Friday, 8:00 A.M. to 4:00 P.M., local time, excluding federal holidays. All deliveries or large movement of equipment, vehicles, barriers, that will impact vehicular access to the facility will be required to be performed outside normal business hours as determined by the COR.

D. The contractor is responsible for all field measurements; the Government will not be held responsible for bidding errors made or the failure to adequately inspect the job site for existing conditions, dimensions and grades or existing utilities. The contractor is responsible for verifying all utilities. After excavation and prior to pipe demolition, install, and backfill grades will be recorded on a drawing and photo documentation will be provided of the layout. The drawing and photographs will be provided to the COR. If there are concerns that arise during construction that indicate an issue with new sewer line check valve the contractor shall elevate the issue to the COR immediately.

E. The VAMC Project COR shall govern all work done during project duration. Prior to any work commencing in the area the contractor shall notify the COR and shall pre-coordinate work with the COR. All outages require COR approval prior to contractor proceeding with the work. In the event that sanitary service will be temporarily unavailable one- week notice is required for facility occupant notification and coordination. Contractor shall not backfill excavation after install of check valve is completed until COR has given full clearance and verification and approval. Disputes shall be promptly referred to the Contracting Officer, (CO). The contractor will immediately correct any work in which the Project COR deems unacceptable or not in accordance with plans and/or specifications.

2.2 Special Considerations and Code Requirements

A. As required by OSHA 29 CFR 1926.651(b)(1), the estimated location of utility installations, such as sewer, telephone, fuel, electric, water lines, or any other underground installations that reasonably may be expected to be encountered during excavation work, shall be determined prior to opening an excavation.

1. All underground utilities in the work area must be positively identified, at Contractor’s own expense, by a private utility locating service. Prior to digging, the Contractor shall submit proof that the underground utilities have been marked and shall obtain approval to dig from the Resident Engineer. Before commencing or engaging in any excavation or demolition or removal of existing structures, the Contractor shall provide notice of the location and date of the planned excavation or demolition to the one-call notification system serving the Medical Center. Such notice shall be served in accordance with Code Rule 53 of the State of New York. When the exact location, dimensions, etc. cannot be verbalized, the Contractor shall pre-mark the work area to adequately identify the work site. The planned dig site will be outlined/marked in white prior to locating the utilities. Use of the American Public Works Association Uniform Color Code is required for the marking of the proposed excavation and located utilities. Digging will not commence until all known utilities are marked. Utility markings will be maintained.

2. Whenever contract work involves chipping, saw cutting, or core drilling through concrete, bituminous asphalt or other impervious surfaces, the existing utility location must be coordinated with station utility departments in addition to location and depth verification by a third party, independent, private locating company. The third party, independent, private locating company shall locate utility depth by use of Ground Penetrating Radar (GPR), X-ray, borescope, or ultrasound prior to the start of demolition and construction. Outages to isolate utility systems must be used in circumstances where utilities are unable to be positively identified. The use of historical drawings does not alleviate the Contractor from meeting this requirement.

3. Excavations will be hand dug or excavated by other similar safe and acceptable means as excavation operations approach within 3 to 5 feet of identified underground utilities. Exploratory bar or other detection equipment will be utilized as necessary to further identify the location of underground utilities.

a. The Contractor must physically verify underground utility locations by hand digging using wood or fiberglass handled tools when any adjacent construction work is expected to come within 3 feet of the underground system. Digging within 2 feet of a known utility must not be performed by means of mechanical equipment; hand digging shall be used. If construction is parallel to an existing utility, the utility shall be exposed by hand digging every 100 feet if parallel within 5 feet of the excavation.

B. The construction project must, at a minimum, be in accordance with all applicable codes including Veterans Affairs standards which can be found at https://www.cfm.va.gov/til/. This will include, but not be limited to: Department of Veterans Affairs Design Manuals, VA Publications, and Construction Standards, National Fire Protection Code (NFPA), Life Safety Code, Underwriters Laboratory (UL), International Building Code IBC, National Electric Code (NEC), the VA Information Security Handbook 6500.6, Occupational Health and Safety (OSHA), NYSCR 56 and Environmental Protection Agency (EPA) requirements. All work will be completed by certified individuals. VA Handbook 0730/4 and the Physical Security Design Manual for VA Mission Critical Facilities.

2.3 Submittals

The contractor shall provide submittals for all items outlined in the specification. The contractor shall not proceed with any on-site work until the completion of the submittal process or approval to proceed from the CO and COR without completion of the submittal process. Not less than 14 calendar days shall be planned for COR review of each submittal. Re-submittals shall be provided as required by the COR, and shall be treated as a new, separate submittal.

2.4 Points of Contract

At the time of award, contractor will provide the names and phone numbers of key personnel who will be the points of contact for Engineering for all issues.

2.5 Period of Performance

The period of performance for this contract is Forty-Five (45) Calendar Days from NTP.
