- WORK STATEMENTAssessment of Manhole #1DOE, Germantown, MD Type of Service. The contractor is required to provide engineering, estimating, assessment, and inspection services for investigating, studying, evaluating, and reporting on the condition of electrical manhole number one and its associated power and other cable distribution conditions at DOE Germantown. Additionally, the contractor is to assure that all energized power wiring in the manhole is de-energized prior to the assessment and that temporary wiring to maintain power during the assessment is installed. Work Plan. The contractor shall prepare and submit a work plan tailored to the specific project being administered. The work plan shall be submitted within (7) calendar days after the receipt of award notification, and shall contain, at a minimum, the following: 1) Description of known characteristics and objectives of the project2) Milestone schedule3) Description of work to be performed4) Estimate of labor-hours to be expended5) Safety plan, including a Dept. of Energy confined space entry permit Progress Report and Records. Keep accurate and detailed written records of the progress of the project. Maintain frequent contact with all parties involved with the project and submit weekly written progress report. Meetings. 1) Schedule and chair meetings as required to discuss procedures, progress, problems, scheduling, and other necessary matters.2) Take minutes of each meeting and provide copies to all attendees within 3 working days. Temporary Wiring and Other Electrician Services. 1) Remove two hundred and forty (240) feet of four (4) abandoned 110 copper conductors that are located in the existing 4-inch conduit from Load Center # 4 to the Manhole. See attached site plan. Temporary Wiring and Other Electrician Services (continued). 2) Provide temporary wiring in the Radio Building (see attached site plan) to maintain power in the building during the assessment of the manhole. This will involve lockout/tag out of two (2) existing 480 V 150 Amp feeders, one (1) in the Boiler House (see attached site plan) and one (1) in Load Center # 4 that serves load in this building. Install 480 V 150 Amp temporary wiring from the existing primary disconnect for DTT-RA-2 to the existing primary disconnect for DTT-RA-1. The room in the Radio Building where the two transformers (DTT-RA-1 and DTT-RA-2) are both located is ten feet (10') X fifteen feet (15').3) Make all the necessary connections to serve DTT-RA-1 from the existing primary feeder to DTT-RA-2. Once Manhole assessment is completed, contractor will remove all temporary wiring and restore all services back to their original condition. Contractor shall maintain proper phasing of conductors during each stage. Maximum outage time for the Radio Building is two (2) hours total. General Services. Investigate and report on the general conditions of the manhole, the condition of electrical distribution systems associated with the manhole, and the condition of the fiber optic cable distribution associated with the manhole. General Conditions of the Manhole. 1) De-energize all power cables. Apply applicable lockout/tag out requirements.2) Check for dangerous gases using a properly calibrated test meter before entering any confined space.3) Inspect cable for sharp bends, physical damage, excessive tension, oil leaks, pits, cable movement, soft spots, cracked jackets, damaged fireproofing, poor ground connections, deteriorated and corroded or weakened cable supports.4) Inspect for cable wear at entrance point and at supports.5) Inspect manhole for spalled concrete, proper ventilation and excessive moisture.6) Check condition of manhole floor drainage and sump pit.7) Check that pulling eyes are located opposite of raceways.8) Check that that manhole cover is stamped clearly thereon with the word ?Electric?.9) Inspect potheads for oil or compound leakage and for cracked/chipped porcelain.10) Examine the manhole and cable grounding system to ensure its integrity.11) If cathodic protection has been installed, evaluate its condition. Power System 1) Check that at each splice and termination point, all shields, ground conductor, etc., are bonded to a ground rod.2) Check that all cables are identified, at the point of entry into the manhole with legible tags. Tags should indicate circuit origin, phase, and destination when terminating at splices. Cables that pass through the manhole should have tags with circuit origin and destination information. In addition, at locations where phase indication is required, indication shall be by the use of color-coded electrical tape.3) Check that driven ground rod has a maximum resistance of 25 ohms. Check that ground rod is cad-welded to the grounding conductor and is connected to a fully closed loop of grounding conductor that is used to bond all splices and non-current carrying electrical equipment in the manhole. Check that grounding connections to racks are made with listed connectors suitable for the purpose. Check that the loop of grounding conductors is between 12 inches and 24 inches above the floor of the manhole and is securely attached to the wall.4) Check that cable in the manhole is properly insulated, on suitable racks, and properly secured.5) Check that cable is properly fireproofed.6) Check that the length of any cable in the manhole is not less than the circumference of the interior of the manhole. For a length of cable that splices or terminates within the manhole, the minimum length of one manhole circumference shall be determined from the point where the cable enters, or exits, the manhole to the splice or termination.7) Check that abandoned cables have been physically removed from the manhole.8) Check that combination power and communication manholes are avoided if possible and that fiber cable is installed in the underground power conduit system if three or more spare power conduits are available between two manholes. Fiber Optic Cable 1) Check that bending radius does not exceed thirteen inches.2) Check that the number of ninety degree turns on a pull does not exceed four.3) Check that 150 feet of cable is coiled at the transition, termination points, and every 1500 feet.4) Note for repair all nicks and cuts in the cable.5) Confirm that the fiber cables in Manhole # 1 are constructed entirely of non-conducting, all dielectric materials for installation around high voltage lines. Fiber Optic Cable (continued) 6) Although fiber cable is made entirely of non-conducting materials, under certain conditions it is still capable of having induced or static charges on its surface. A static surface charge can be dangerous if touched bare handed. To insure the safety of field operations personnel, check that all fiber cable installed in the manhole is grounded. Fiber cable is more susceptible to crushing than regular conductors, so proper grounding techniques should be verified.7) Check that the fiber cable is protected from underground electrical conductor arc and burn, which may include wrapping with fire retardant tape and fire resistant cloth bags for extra cable coils.8) Check that fiber cable, coils, and splices are kept in the bottom of the manhole so as to be out of the way of the electrical conductors and equipment.9) Check that manholes containing fiber are marked externally and permanently adjacent to the manhole. Compliance with Codes and Standards. All studies, analyses, and recommendations must comply with the latest issues of constructions codes and standards. Such codes shall include, but not be limited to NFPA and National Electrical Code. Investigative Report. Projects requiring an investigative report shall be thoroughly investigated at the site. The site investigations shall be accomplished by the professional disciplines trained in the area of the related work. Field investigations shall include a thorough check of all conditions and locations of the area affected by the proposed work. All available information relative to existing conditions, will be made available to the investigator, who shall research, reproduce, evaluate and verify such information as necessary to perform the work as stated herein. All site visits shall be coordinated with the COR at least 48 hours in advance of the expected visit. Itemized implementation cost estimates for all recommendations shall be included with the report.
