SCOPE OF WORK I. GENERAL The Contractor shall perform an Arc Flash Analysis for the Stratton VA Medical Center (VAMC), Albany NY. SPS area basement building 1. The study shall include the entire electrical system within the area. It shall begin at the incoming utility electrical service in room S-22 in the subbasement and continue through to each branch circuit panelboard, Attached is the 2014 Study for bid purposes. The area has changed somewhat over the last 6 years. The purpose of this study is so that the area s electrical system will be in compliance with VHA Directive 1028 and NFPA 70E (2018) which requires an arc flash analysis every five years. All work shall be accomplished in strict compliance with VHA Directive 1028, NFPA-70E, 2018 Edition (Standard for Electrical Safety in the Workplace), Institute of Electrical and Electronics Engineers (IEEE) Standard 1584-2002 and IEEE 242-2001, Recommended Practice for Protection and Coordination of Industrial and Commercial Power Systems. All survey work will be accomplished on energized equipment unless an outage is required due to specific equipment safety conditions. All requests for outages must be submitted in writing to the COR and approved by the Facility Director and Facility Manager/O&M Manager. VA staff will be able to assist the Contractor in accessing/opening electrical equipment. The Contractor shall conduct an entrance briefing with the Facility Manager/O&M Manager or designees upon arrival at the Stratton VA Medical Center. The Contractor shall use the meeting to introduce him/herself and to discuss the procedures for obtaining the necessary drawings and field information. At the completion of the survey, the Contractor shall conduct a short briefing with the Facility Manager/O&M Manager or designee to discuss any major problems or life threatening issues if any are discovered during the survey. Consulting Engineer shall document the meeting in minutes. All information obtained during site visits or any conditions discovered during subsequent calculations shall be kept in strict confidence. The arc flash analysis will include site visits to the Stratton VA Medical Center by a team from the Contractor. The contractor s team members will consist of experienced, professional staff having extensive knowledge in the field of electrical power and shall include at least one registered professional electrical engineer, whom shall be responsible and in control of all work. The Contractor will be responsible for obtaining all necessary data for these reports from as-built drawings, field investigations, previous area ARC Flash from 2014 and from available VAMC staff (utilizing the staff s knowledge and familiarity of the facility electrical systems). Information for site electrical utilities will also be gained from as-built drawings and contractor s personal inspection of these utilities. Information, including drawings and other documentation, provided to the Contractor, shall be used for reference only and may not be 100% accurate or may not exist. The Contractor shall field verify everything and shall not use any drawings provided for plan or elevation views. The drawings submitted shall be originals and shall be the result of the field check, and shall not be take-offs or tracings, for any drawings or other information provided. The arc flash analysis shall be conducted using SKM Power Tools or equivalent electrical system modeling software. A copy of the software model and data files used to develop the study shall be turned over to the VAMC for the facility s use and modification for future facility work (e.g. creation of updated arc flash hazard warning labels). Baseline Review (BR). Approximately 10-15 days after submitting the 90% documents but before completing the Final Submission documents, the Contractor will coordinate and conduct a Baseline Review meeting with the respective VAMC staff. This meeting may be held telephonically unless the Consulting Engineer determines that an on-site meeting is warranted. At this meeting, the lead Engineer of the Consultant s team shall provide the Users (i.e. O&M Manager, COR) a prioritized overview of the deficiencies found and the potential consequences if such deficiencies are not corrected. In short, the Consulting Engineer should review the findings of the study with VAMC staff and explain the inherent risks and respond to any questions regarding the study. At conclusion of the BR, the Consulting Engineer shall document the meeting in minutes indicating the VAMC has received the study and have been apprised by the AE for associated risks. Copies of these minutes shall be included in the Final Submission documents. The Contractor is responsible for providing records for all meeting minutes and providing them to the VAMC. The meeting minutes shall include every topic discussed as well as a list of attendees. The meeting minutes will be emailed to the VAMC within a week after the meeting. The Contractor shall retain copies of everything submitted. The intent of this requirement is to save time, whereby many questions can be resolved by telephone and to ensure that true copies are available in the event of loss or damage during the reproduction cycle. The Contractor shall correct any errors, omissions or deficiencies in their performance and products without additional cost to the Government. II. QUALIFICATIONS The Protective Device Coordination Study and Arc Flash Hazard analysis shall be conducted under the supervision and approval of a Registered Professional Electrical Engineer skilled in performing and interpreting Arc Flash studies. The Registered Professional Electrical Engineer shall be a full-time employee of the engineering firm. The Registered Professional Electrical Engineer shall have a minimum of three (3) years of experience in performing power system studies. The engineering firm shall demonstrate experience with Arc Flash Hazard Analysis by submitting names of actual arc flash hazard analysis it has performed in the past three years. III. SPECIFIC SCOPE OF WORK One Line Diagrams: The one-line diagrams shall show the schematic wiring of the electrical distribution system for this area. Include all electrical equipment and wiring protected by the over current devices. Also show on the one line diagrams the following specific information: Calculated Short Circuit values at each bus Breaker and fuse ratings Transformer kVA, voltage ratings and wiring connections Voltage at each bus Identification of each bus Conduit material, feeder sizes and lengths Arc Flash Hazard Analysis: The arc flash hazard analysis shall be performed according to the IEEE Std. 1584-2002 equations that are presented in NFPA70E-2018, Annex D. The flash protection boundary and the Incident Energy shall be calculated at all equipment locations. The Arc-Flash Hazard Analysis shall include all significant locations in 240 volt, 208 volt and 110 volt systems fed from transformers equal to or greater than 125 kVA where work could be performed on energized parts. Safe working distances shall be based upon the calculated arc flash boundary considering Incident Energy of 1.2 cal/cm^2. When appropriate, the Short Circuit calculations and the clearing times of the phase overcurrent devices will be retrieved from the Short-Circuit and Coordination Study model. Ground overcurrent relays should not be taken into consideration when determining the clearing time when performing Incident Energy calculations. The short-circuit calculations and the corresponding Incident Energy calculations for multiple system scenarios shall be compared and the greatest Incident Energy must be uniquely reported for each equipment location. Calculations must be performed to represent the maximum and minimum contributions of fault current magnitude for all normal and emergency operating conditions. The minimum calculation will assume that the utility contribution is at a minimum and will assume a minimum motor contribution (all motors off). Conversely, the maximum calculation will assume a maximum contribution from the utility and will assume the maximum amount of motors to be operating. Calculations shall take into consideration the parallel operation of synchronous generators with the electric utility, where applicable. The Incident Energy calculations must consider the accumulation of energy over time when performing arc flash calculations on buses with multiple sources. Iterative calculations must take into account the changing current contributions, as the sources are interrupted or decremented with time. Fault contribution from motors and generators should be decremented as follows: Fault contribution from induction motors should not be considered beyond 3-5 cycles. Fault contribution from synchronous motors and generators should be decayed to match the actual decrement of each as closely as possible (e.g. contributions from permanent magnet generators will typically decay from 10 per unit to 3 per unit after 10 cycles). For each equipment location with a separately enclosed main device (where there is adequate separation between the line side terminals of the main protective device and the work location), calculations for Incident Energy and flash protection boundary shall include both the line and load side of the main breaker. When performing Incident Energy calculations on the line side of a main breaker (as required per above), the line side and load side contributions must be included in the fault calculation. Mis-coordination should be checked amongst all devices within the branch containing the immediate protective device upstream of the calculation location and the calculation should utilize the fastest device to compute the Incident Energy for the corresponding location. Arc Flash calculations shall be based on actual overcurrent protective device clearing time. Maximum clearing time will be capped at 2 seconds based on IEEE Std. 1584-2002 section B.1.2. Where it is not physically possible to move outside of the flash protection boundary in less than 2 seconds during an arc flash event, a maximum clearing time based on the specific location shall be utilized. Arc Flash Labeling: Contractor shall produce and deliver and affix arc flash warning labels to the VAMC in accordance with NFPA 70 (NEC) and NFPA 70E. Labels shall be 4 x 6 (nominal) printed on industrial quality, adhesive backed vinyl. DANGER labels shall have pre-printed headers in red; WARNING labels shall have pre-printed headers in orange. All outdoor labels will be weatherproof and UV resistant. Electrical equipment shall be labeled IAW NFPA 70, Articles 110.16 & 100.21(B) and NFPA70E, Article 130.5 (C). The arc flash hazard analysis to determine the Arc Flash Protection Boundary for each label shall be calculated IAW NFPA 70E Paragraph 130.5 (B). For each device for which a hazardous analysis is conducted, the equipment shall be provided with an arc flash hazard warning label compliant with the requirements of NFPA 70E Art. 130.5(D) containing the following: Nominal system voltage Arc flash boundary At least one of the following: Available incident energy and the corresponding working distance, or the arc flash PPE category in Table 130.7(C)(15)(A)(b) or Table 130.7(C)(15)(B)for the equipment, but not both. Minimum arc rating of clothing Site-specific level of PPE In addition to the requirements of NFPA 70 and 70E, each customized label shall identify the corresponding piece of electrical equipment, by Panelboard or device identifier and Building number. The identification shall be in a manner (nomenclature) understood by VAMC personnel who will be applying the labels to the respective devices. Generic labels do not require equipment and building identifiers. Arc flash labels shall be provided in the following manner and all labels shall be based on recommended overcurrent device settings. For each 15KV, 480V, 208V and 110V panelboard, one arc flash label shall be provided. For each motor control center, one arc flash label shall be provided. For each low voltage switchboard, one arc flash label shall be provided. For each switchgear, one flash label shall be provided. For each medium voltage switches one arc flash label shall be provided. For each machine control panel, one arc flash label shall be provided. For each bus duct plug, one arc flash label shall be provided. Protective Device Coordination Study: Prepare the coordination curves to determine the required settings of protective devices to assure selective coordination. Graphically illustrate (using log paper) that adequate time separation exists between series devices, including the utility company upstream device. Plot the specific Time Current Characteristics (TCC) of each device in the electrical system as follows: Provide TCC curve down to the last branch-circuit panelboard (regardless the protective device is an adjustable or fixed device) in the three-branches of the Essential Electrical System (EES). Provide TCC curve down to the last adjustable device (stop after the first fixed device) in the Normal System but at the minimum two-level curves from each of the building Service Entrance switchgear/switchboard shall be provided. The following specific information shall also be shown on the coordination curves at each level of power distribution system: Device identification (including Manufacturer, Catalog Number, and Device Curve Number and ID) Voltage and current ratio for curves. 3-phase and 1-phase ANSI damage points for each transformer. No-damage, melting, and clearing curves for fuses. Cable damage curves. Transformer inrush points. Maximum Short Circuit cutoff point. Excerpts from one-line diagram reflecting the protective devices modeled on each curve. This excerpt may be inserted onto a corner (typically top right-hand) of the curve print out or may be on the preceding facing page for ease of reference. Provide explanation, analysis, and recommendation to achieve better coordination. The analysis for recommended curve of a device shall be put right after the existing curve in the report for comparison. Develop a table to summarize the settings selected for the protective devices. Include all medium voltage devices in the table, as well as all low voltage devices which require modification, showing the following data: Device identification. Relay CT ratios, tap, time dial, and instantaneous pickup. Circuit breaker sensor rating, long-time, short-time, and instantaneous settings, and time bands. Fuse rating and type.
