Building 23R Room G03:

This space is considered a satellite electrical room with internal heat gain (see requirements in Table 1 above).

Transformer heat dissipation to be estimated at a rate of 3% of the anticipated actual peak demand. Rated nameplate capacity shall not be used for equipment heat gain.

Mechanical cooling

Provide a dedicated mechanical cooling unit refrigerant direct expansion (DX) as he cooling medium. Cooling shall be available on demand.

o With the 0.4% design day weather data, mechanical cooling will need to be provided during peak conditions to maintain the space temperature.

Provide minimum outdoor air in mechanical cooling mode.

Avoid installing mechanical cooling units within the electrical room to prevent possible damage due to water leakage and/or overflow of condensate drain pans.

Provide a thermostatically controlled heating system only if the space heat gain cannot offset the design heat load.

o The current equipment heat gain dissipated to the room is larger than the design heat load, so a heating mode will not be required.

Provide a DDC sensor to monitor the space temperature and initiate local and remote alarms in the event space temperature exceeds 95°F. Provide a DDC sensor for monitoring and alarm with local control loop. Coordinate with Johnson Controls to tie monitoring and alarm into existing Metasys system.

Direct Expansion Requirements:

Equipment selection shall comply with the minimum Energy Efficient Ration outlined in the latest version of ASHRAE Standard 90.1.

Refrigerant piping layout shall be reviewed and approved by the equipment manufacturer. Filter-driers are required, if they are not installed at the factory, they shall be field installed.

Select two compressors in parallel, where feasible, in place of a single compressor to facilitate part load operation and provide partial redundancy. With two compressors serving a single DX coil, provide intertwined coil circuiting to facilitate refrigerant flow through the entire coil even with one compressor in operation.

Chlorofluorocarbon (CFC)-based refrigerants shall not be used in new construction or equipment. Utilize refrigerant types that have an ozone depletion potential (ODP) of zero

(ex. R-134a, R-410a, R-407c, etc.)

With outside air temperatures exceeding maximum space temperatures during peak summer heat, the initial plan to use exhaust fans will not work during the whole year; mechanical cooling will need to be installed and operated during the peak summer hours.

Louvers or transfer diffusers will need to be installed to meet the air change requirements.

At the 95% submission, Building 2 Rooms BD108 and BD106A were removed from scope.

1.1.5 SYSTEM SELECTION – MEP (ELECTRICAL)

This project shall upgrade the existing electrical infrastructure and equipment to comply with VA electrical systems requirements. The design will comply with applicable VA design guides.

The VA has provided recommended actions for each item as indicated in the SOW; further general requirements for each item have been provided in the SOW.

UTILITY COMPANY CORRESPONDENCE:

A/E was provided with utility peak demand power load information. The demand will be used to determine a seasonal adjustment factor to 30-day metered loads – providing more accurate load study results.

LOCATION AND SIZE OF:

Each building and floor were analyzed and verified for the existing conditions and the required improvements for each of the following items as they fall in the SOW:

Electrical equipment

Electric closets

Electrical distribution equipment

EXISTING EMERGENCY GENERATOR SYSTEM CAPACITY:

The existing emergency generators system has been analyzed and determined to have sufficient capacity for the existing load.

POWER SYSTEM FINDINGS, RECOMMENDATIONS, AND SOLUTIONS:

The power software used to conduct the following calculation and analysis is PTW SKM.

VOLTAGE DROP AND DEMAND CALCULATIONS:

Voltage drops and power demand calculations were conducted using 80% load demand, and the results were analyzed and compared against NEC, IEEE, and VA Design Manual. This information will be used to size electrical distribution equipment including, but not limited to, cables/conductors, raceways, and panelboards. Based on the analysis, high voltage drop values were observed at multiple locations. The high voltage drops values observed are due to the modeling approach used to model the system and run the voltage drop and demand calculations. The approach used assumes all the panels are operating at 80% capacity. This approach is the worst-case scenario and will rarely be observed within the system.

Load recordings were placed at SUB 1, SUB 2, AND SUB 3 transformers. The results show that the transformers loading remain within the capacity of the transformer.

The harmonic readings are adequate for all three transformers.

SHORT-CIRCUIT CALCULATIONS:

Short-circuit calculations were conducted using utility information provided by AEP.

Equipment that was found to have an inadequate AIC rating will be replaced as part of the scope of the work discussed below.

ARC FLASH CALCULATIONS:

Arc Flash calculations were conducted using utility information provided by AEP.

Locations that have an incident energy above 40 Cal/cm2 will be provided with an additional label showing a safe working distance that will provide a lower incident energy value.

LIFE CYCLE ANALYSIS FOR ELECTRICAL SYSTEMS:

All existing electrical equipment that requires a life cycle analysis were evaluated. It was determined that if the existing equipment is past its time of use or shows signs of possible future failure due to wear and tear, the equipment will be replaced per the obsolete phasing plan. The scope of work shown below will contain further details for panels that will be repaired.

LIST OF SPECIALTY AREAS:

No specialty areas are included in the subject project currently.

DESIGN:

All existing panelboards proposed to be replaced were load monitored to determine the peak demand. The load monitoring was performed for 30 days per NEC 220.87 requirements.

Where grounding deficiencies were observed, revision will be made to comply with VA standards and NEC.

Testing of 16 existing electrical oil transformers was conducted to determine if they meet current VA TIL and code requirements.

Testing and documenting all ground electrode locations and evaluating conditions.

ELECTRICAL SCOPE OF WORK:

Obsolete NEHB Panels:

The NEHB panelboard is obsolete. EH and EHB circuit breakers used in the NEHB panelboards are no longer available. If the protective devices fail for these types of panelboards, replacements are no longer available. Appendix B displays the list of obsolete NEHB panelboards that need to be replaced. The panels enclosures will remain. The panel inserts and internal components including circuit breakers, busbar, dead front, and cover will be replaced with a NEHB retrofit. The retrofit will eliminate the faulty dead front. It will also enable the panel to accept circuit breakers that are currently manufactured by Square D. The use of a retrofit insert will also reduce the downtime that would otherwise be required if the entire panel were to be replaced. The contractor shall return the removed NEHB circuit breakers to the VA to be used as spare until all the NEHB panels are replaced.

The contractor shall coordinate with Graybar for interior assemblies. The contact information is the following:

BLDG 12 (Bid Alternate): SOW states “Addition electrical panel capacity is needed”:

Davenergy performed a load study for the following panels PPN-1A, PPN-2A, and

12_MDP.

o It was determined that PPN-1A has sufficient space and capacity to add additional loads. PPN-1A connected load is at 27%. No additional work required.

o It was determined that PPN-2A has sufficient space and capacity to add additional loads. PPN-2A is connected load at 29%. No additional work required.

o It was determined, 12_MDP has sufficient capacity to add additional loads but does not have sufficient space within the panel to add additional circuits.

BLDG 17-Panel 3_INCINERATOR:

Panel 3_INCINERATOR is missing the dead front cover, exposing its energized conductors and busbar.

Replace panel with new panel of the same size, rating and circuit count.

BLDG 25

Panel 25_LPN-GA, classified as a NEHB type panel, is being replaced due to its obsolescence. It will be upgraded to a new 42-circuit panel.

SWITCHGEAR SUB 1 - Circuit Breaker 52F-3A:

Spare circuit Breaker 52F-3A will need to be tested and repaired if needed to be in working operation for future use.

BLDG 2 – BD106AS – Electrical Equipment Relocation

The equipment marked as future (F) will be installed at a future date and is not within the scope of work for this project.

Overloaded panels for replacement (Bid Alternate):

The panels identified in Appendix C will need to be replaced and upsized since they have either reached or exceeded their load capacity. This poses a hazard and affected panels will need to be replaced and upsized. The replacement of these panels will be conducted in a future project.

Failed Equipment Evaluation Report:

The panels identified in Appendix D will need to be replaced and upsized because they are underrated. The calculated available fault current or voltage levels are above the rated capacity of the protective devices and panel. This poses a hazard and will need to be replaced with equipment that is properly rated.

Lightning and Grounding Test:

The grounding test conducted by EPS shows acceptable resistance values per VA and NEC requirements. See Appendix E for results. The lightning results provided by EPS show resistance values above the desired range. High resistance can indicate a poor connection or damaged connection, which can lead to the generation of heat and potentially cause a fire or electrical shock hazard.

Replace the existing lightning protection to comply with the latest NEC, NFPA 780, and VA Electrical Design manual requirements.

Substation Transformer SUB 1, SUB 2 (Bid Alternate), and SUB 3 (Bid Alternate) :

A/E proposes to replace SUB 1, SUB 2 (Bid Alternate), and SUB 3 (Bid Alternate).

Load recordings were installed on each of the transformers to determine the existing loading capacity. Based on the load recordings, the transformers are still operating within the recommended capacity, therefore, the transformers will be replacing similar rating as the existing transformers. In addition to the oil transformer replacement, an oil containment berm will be installed for each of the transformers. The transformer shall be biobased FR3 fluid.

The contractor shall dispose of existing oil-filled transformers as required by the

AHJ.

Protective Device Coordination settings:

The power system study found coordination deficiencies that will need to be corrected. The contractor will adjust the protective device settings based on the power system study results. See Appendix G for proposed coordination adjustments.

Prior to modifying the settings, the existing settings are required to be documented on sheet E-802. Each breaker requiring setting adjustments has an “As Found” and “As Left” row. The contractor is required fill out the “As Found” and “As Left” settings.

Figure 1: Snip From Coordiantion Table on E-802.

Power Meters (Bid Alternate):

Power meters will be installed for optimal ongoing energy efficiency studies. The power meters will be SEL or equal and will communicate with COPA-DATA. The power meters and COPA-DATA will provide real-time and historical data.

1.1.6 SYSTEM SELECTION – FIRE ALARM

Design shall be in accordance with the latest editions of the NFPA 101 Life Safety Code, VA Fire Protection Design Manual, and the International Building Code (IBC). Where life safety systems are impacted during construction, the design shall address interim life safety measures to be implemented as part of the construction documents. Any new fire alarm devices required shall be specified to match the existing installed base to provide conformity and modularity.

The new main fire alarm system will be required to be installed and coordinated with VA project 581-19-105. A detailed survey will be required to verify if the existing sub-panels and devices can properly work within the new system.

The existing fire alarm system in place at the Huntington West Virginia Campus is an Edwards brand system. The current fire panel models are all EST-3 panels. The AE will design an upgrade from these EST-3 panels to EST-4 panels, which are the newest panels offered by Edwards.

A total of 19 panels and 4 annunciators have been identified throughout the campus. Those panels and annunciators are located in the following buildings,1, 1A, 1S-26, 1W, 2, 3-34, 4, 5, 6, 7-28, 8, 12, 23-23R, 1A-ANN, 1-ANN, 23M-ANN, 20, 9, 21-ANN, and 3. The fireworks management software resides on a PC located in Building 3 and connected to panel 19. As part of this upgrade, the Fireworks software will be upgraded to the latest version and will reside on a new UL listed PC. The VA may wish to relocate this PC since building 3 (the boiler plant) has been slated for demolition in the future. The new system to be installed is to have a phone notification feature and annunciator to notify VA staff. Until that point the fireworks annunciator needs to operate and be monitored from Building 3.

There are some components that are integral to the EST-3 panels that can be repurposed and utilized in the new EST-4 panels. The AE will not identify those components in the drawings due to the Contractor needing to determine at the time of removal whether they are in good working order or not. AE will note on the drawings that any and all useable components be repurposed.

A site survey by the current Contractor servicing the fire alarm system at the VA indicates that all existing power circuits and tie cables between panels, buildings and annunciators are also in good working condition and will not need to be replaced. Patch cables whether fiber or copper will be replaced at the time of the upgrade of the panel. A new umbilical cable or terminal cabinet will need to be installed that can be relocated to the new Boiler Plant to be constructed.

The Contractor will dispose of all unused components, panels, batteries, power supplies, doors and other parts that are removed, in a proper and environmentally friendly manner in accordance with VA Master Specification 01 74 19.

Post upgrade of each individual panel, the panel will be 100% tested by the installing contractor and in compliance with all applicable NFPA codes and requirements. The VA will be notified prior to any testing being scheduled in order for the VA to assign a staff member to witness the testing if desired. The local fire department will also be notified of the project prior to the start and will be invited to be present during the testing phase.

In scope for this project is also the addition or replacement of individual fire alarm signaling devices, such as but not limited to Smoke detectors, heat detectors, strobes and manual pull stations. These device replacements will occur only in buildings 17, and Trailers 2 and 3. Any device(s) that do not result in a positive test result will be replaced at the time of testing. The existing devices in building 17 are known to not be addressable devices and will be disposed of after replacement.

The following design parameters will apply:

National Fire Protection Agency (NFPA) OSHA Standards National Electric Code

1.1.7 SYSTEM SELECTION – MEP (PLUMBING)

Building 51 will require an eyewash station to be demolished and a new combination sink / eyewash station to be added to the room. Piping to be routed to existing lines. The existing hose bib will be relocated to the new sink location.

Transformer pads adjacent to Building 26 require an oil/water separator to be installed for each of the two pads, for a total of two oil/water separators. Separator locations shall be coordinated with onsite VA staff and will be installed per manufacturer’s instructions.

Separators will be located inside of the fenced area. The drain line running from the separator will terminate outside of fenced area along the hillside adjacent to Building 26.

1.1.8 SYSTEM SELECTION – STRUCTURAL

This design does not require any structural work.

1.1.9 SYSTEM SELECTION – LIFE SAFETY AND FIRE PROTECTION

At this point in the design the existing sprinkler locations have been reviewed to confirm if they exist within a code defined Working Space or Dedicated Electrical Space. Based on info gathered onsite, there do not appear to be conflicts within the area / scope of work. Other areas of concern have been identified and a letter provided to the VA.

1.1.10 PHYSICAL SECURITY

Physical Security Requirements from PSRDM for Electrical Rooms have been incorporated and defined as the design progressed.

1.1.11 OWNER SUPPLIED SYSTEMS

No owner-supplied systems will be required.

1.1.12 PHASING

The contractor shall provide a detailed plan for replacing the electrical panels and should be categorized by building and floor. The plan should also include a detailed scope of work that outlines the specific areas where new electrical panels will be installed; including the locations where temporary panels will be required, locations where panels are to be installed adjacent to the existing panels, and the steps necessary to ensure a smooth transition of loads from the old electrical panel to the new electrical panel.

It is crucial that the contractor considers any safety concerns that may arise during installation. This includes ensuring that all necessary safety measures are taken to prevent any electrical hazards, disruption to hospital service, or accidents from occurring.

The contractor is required to conduct a thorough site survey to identify any potential issues that may have an impact on the installation process. This could include issues related to access to electrical panels, existing wiring, disruption to hospital service, or other elements that may impact the installation.

Executive Summary

This document reports the findings and recommendations of a lightning protection system inspection conducted at the Hershel ”Woody” Williams VA Medical Center. The inspection revealed that the current system does not comply with the NFPA 780 and NEC standards, and has several issues that compromise its performance and safety. The main issues are:

� Inadequate test points for the system connection to the grounding system

� Improper termination of the down cable at the structural steel, plumbing, and electrical conduit

� Lack of previous testing data to assess the condition of the connection points.

� Missing or damaged lightning protection system components.

The recommendation is to replace the current system with a new one that follows the best practices and codes for lightning protection. This would be more cost effective and safer than repairing the existing system, which would require extensive labor and materials, and would not guarantee that all potential issues will be addressed. Replacing the system would ensure that the system is up to date and reliable, and it would reduce the risk of damage to the buildings and equipment, as well as injury to the occupants.

1 Narrative

This design narrative provides a lightning and grounding findings and recommendations for the project ”Upgrade Electrical Infrastructure” located in Huntington West Virginia. The project involved performing a lightning and ground system evaluation. The VA electrical design manual, NEC, and NFPA 780 codes used to perform the site evaluation and provide recommendations to correct any deficiencies. The following list shows the prevailing deficiencies found throughout Hershel ”Woody” Williams VA Medical Center.

� Lack of test or Connection point on each of concrete-encased electrode to enable periodic maintenance and testing of the grounding and lightning protection.

� Test report show lightning protection resistance above NFPA 780 requirement.

� Lightning protection cable not fastened to roof.

� Lightning protection not connected to metal roof equipment.

� Lightning rod missing.

� Down conductor disconnected from roof conductor protection.

� Grounding down conductor should terminate at the ground and connect to the grounding electrode system, but in multiple locations, the grounding down conductor terminate at structural steel, plumbing and in some cases electrical conduit.

� There is lack of ground system test or connections points on each of concrete-encased electrode locations that prevent the equipment to be periodically maintained and tested.

� There is a lack of routine maintenance and testing that prevent the Lightning protection to be evaluated and analyze to determine the rate at which the lightning protection is derating.

� Building 4 does not have lightning protection and is outside the overall zone of protection from an adjacent building.

� Building 9 does not have lightning protection and is outside the overall zone of protection from an adjacent building.

� Building 28 does not have lightning protection and is outside the overall zone of protection from an adjacent building.

� Building T3 does not have lightning protection and is outside the overall zone of protection from an adjacent building.

� Building T4 does not have lightning protection and is outside the overall zone of protection from an adjacent building.

� Building T5 does not have lightning protection and is outside the overall zone of protection from an adjacent building.

These issues were found in multiple locations throughout the site building roofs. The issues discussed in further detail below are prevalent through out the entire site and or not limited to the location identified.

The lightning protection system should comply with the VA Electrical Design Manuel, NFPA 780 and NEC standards, but the current system does not meet these requirements. Therefore, we recommend replacing the system with a new system that follows the best practices and codes for lightning protection.

Replacing the system would be a much more cost effective rout as it would require far less long term cost for the station. It would also be safer than attempting to repair the existing system. Repairing the existing system would require far more intrusive study, require extensive labor, and materials; however it would not guarantee that all potential issues will be addressed. The lightning and grounding protection connection points are encased in concrete. To further inspect these connections points, excavations would be need to expose the system and perform further testing. Replacing the system would ensure that the system is up to

3 of 19 Hershel ”Woody” Williams VA Medical Center date and reliable, and it would reduce the risk of damage to the buildings and equipment, as well as injury to the occupants.

The following are common issues found throughout the site and were found to impede the lightning protection from performing optimally.

2 Test Report

The following reports show that test results for the lightning and grounding protections. The ground results show adequate values at the test points, however the locations where the lightning protection and grounding electrical system connect is unknown as there is no test or connection point provided on each of the concrete-encased electrode.

The lightning protection at locations 2, 3, 9, 10, and 14 show undesired values. The current lightning protection equipment does not have test point where the system connects to the grounding system, therefor, it would require excavating to expose the connection points and determine the condition of the down cable and ground system connection. There is also locations where the down cable terminate at the structural steel, plumbing, and electrical conduit. The down conductor should be isolated from the electrical grounding system and only connect at one location. This allowing the lightning current a direct path to ground without causing any damage to the electrical equipment and personal. Since there is no previous testing data, we are not able to asses the rate of deterioration the connections points that are adequate but may potentially be failing.
