- Upgrade Lightning Protection System Synopsis Solicitation Number: W912JB-18-B-5002 Restrictions: Small Business Title: Upgrade Lightning Protection System Location: Selfridge Air National Guard Base, MI 48045 (Macomb County) Issue Date: Tentatively 25 May 2018 Pre Proposal Conference and Site Visit: Tentatively 12 June 2018 10:00am Closing Date: Tentatively 25 June 2018 2:00pm Award Date: Tentatively 20 July 2018 UPGRADE LIGHTNING PROTECTION SYSTEM - The Selfridge Air National Guard Base has a need for repairs for the building lightning protection system. The scope of work for this construction project provides for, but is not limited to: 1) Building 05 (Hanger Building): a. Existing Lightning Protection System (LPS): No LPS exists for this building. However, an existing antenna mounted on the roof in addition, the existing gas meter has conductors that terminate to their own ground rod. b. LPS Deficiencies and Government Required Corrective Action: Since the roof has a span of over 40 feet and the slope is 1/4 or greater, this roof is defined as pitched (in lieu of flat or gently sloped). Therefore, an LPS system shall be based on a pitched roof as prescribed in NFPA 780, which includes, but are not limited to the following protection: air terminal shall be within 2 feet of each roof top ridge edge, air terminals along roof top ridge with 20 feet maximum spacing. Propose route down conductors from each top ridge edge down to bottom ridge edge and down the façade of the building to a grounding rod for each down conductor such that ground rods are at diagonal ends of the building, and an air terminal shall be added to the roof exhaust fan. Since this roof has multiple/intermediate ridges, additional protection will be required (i.e. additional down conductors and ground rods). Since this building does not exceed 60 feet in height, an exterior ground ring is not required. Refer to Drawing for existing and proposed LPS layout. This LPS as well as the antenna and gas meter grounding shall be bonded back to the building main ground bar inside the Main Distribution Panel(s) of this building. 2) Building 09 ASR (Airport Surveillance Radar): a. Existing Lightning Protection System (LPS): No LPS exists for this building. However, an existing antenna mounted on the roof and the existing gas meter has conductors that terminate to their own ground rod. b. LPS Deficiencies and Government Required Corrective Action: Since the roof has a span of over 40 feet and the slope is 1/4 or greater, this roof is defined as pitched (in lieu of flat or gently sloped). Therefore, an LPS system shall be based on a pitched roof as prescribed in NFPA 780, which includes, but are not limited to the following protection: air terminal shall be within 2 feet of each roof top ridge edge, air terminals along roof top ridge with 20 feet maximum spacing. Propose route down conductors from each top ridge edge down to bottom ridge edge and down the façade of the building to a grounding rod for each down conductor such that ground rods are at diagonal ends of the building, and an air terminal shall be added to the roof exhaust fan. Since this roof has multiple/intermediate ridges, additional protection will be required (i.e. additional down conductors and ground rods). Since this building does not exceed 60 feet in height, an exterior ground ring is not required. Refer to Drawing for existing and proposed LPS layout. This LPS as well as the antenna and gas meter grounding shall be bonded back to the building main ground bar inside the Main Distribution Panel(s) of this building. 3) Building 12 Aircraft Shelters (Sunshades): a. Existing Lightning Protection System (LPS): LPS exists for this building, which consists of one air terminal at the center of each of the twelve pitched roofs. For each air terminal, the down conductor was routed along the roof and bonded to the top of the structural steel. A ground rod was located at each outside structural beam. A grounding electrode conductor was bonded to this ground rod and to the bottom of the structural beam. Approximately 6" of the ground rod are exposed and the remaining portion of ground rod has been embedded in the concrete pavement. b. LPS Deficiencies and Government Required Corrective Action: Since the roof has a span of over 40 feet and the slope is 1/4 or greater, this roof is defined as pitched (in lieu of flat or gently sloped). Therefore, an LPS system shall be based on a pitched roof as prescribed in NFPA 780, which include but are not limited to the following protection. Air terminal shall be within 2 feet of each roof top ridge edge, air terminals along roof top ridge with 20 feet maximum spacing, route down conductors from each top ridge edge and bond to the outside edge of structural steel. The ground rods and at each outside structural beam and its bonding electrode conductor shall remain. A couple of the ground rods (over time) have moved up to where less of the rod is embedded in the concrete pavement. These rods need to be driven in the ground, via hammer, such that 6" of the ground rod is exposed. The existing air terminal at each sunshade was observed and is believed to be an ESE (Early Streamer Emission) type in lieu of a conventional type air terminal. This ESE type air terminal is not recognized by NFPA 780 and is not a UL 96 listed lightning protection component. Refer to UFC 3-675-01, Chapter 1-5, and Key Codes, Standards, and Chapter 3-1, paragraph 2, which states, "If lightning protection is required, provide a lightning protection system (LPS) in accordance with NFPA 780 criteria using components manufactured in accordance with UL 96. Provide a UL Lightning Protection Inspection Certificate for the facility certified to NFPA780, unless the design and inspection are otherwise identified to comply with a different standard for a specific facility." Therefore, since conventional in lieu of ESE air terminals are recognized by NFPA 780 and are UL 96 listed components, the existing air terminal shall be removed from each of the twelve sunshades and new conventional air terminals shall be added. Since this building does not exceed 60 feet in height, an exterior ground ring is not required. Refer to Drawing for existing and proposed LPS layout. 4) Building 15 Shop, Jet Engine Maintenance Repair: a. Existing Lightning Protection System (LPS): A very limited LPS exists for this building, which consists of an air terminal, one for each of the two flues/vents, with a conductor routed down the façade of the building and terminated to a ground rod. An existing antenna tower and the existing gas meter have conductors that terminate to their own ground rod. b. LPS Deficiencies and Government Required Corrective Action: The LPS system shall be based on a flat roof as prescribed in NFPA 780, which include but are not limited to the following protection: air terminal shall be within 2 feet of each corner for the upper and lower roofs. Air terminals shall be along the perimeter of the upper and both lower roofs 20 feet apart, the down conductors and associated ground rod for the two existing flues/vents shall be removed, and down conductors shall be routed on the diagonal end of the building. Since this building does not exceed 60 feet in height, an exterior ground ring is not required. Refer to Drawing for existing and proposed LPS layout. This This LPS as well as the antenna and gas meter grounding shall be bonded back to the building main ground bar inside the Main Distribution Panel(s) of this building. 5) Building 24 Shop A/SE Storage Facility: a. Existing Lightning Protection System (LPS) A very limited LPS exists for this building which consists of an air terminal, one for each of the two flues/vents, with a conductor routed down the façade of the building and terminated to a ground rod.

Existing Lightning Protection System (LPS) Since the roof has a span of over 40 feet and the slope is less than 1/4, this roof is defined as gently sloped (in lieu of pitched). Therefore, the existing LPS system is evaluated based this roof type as prescribed in NFPA 780. Gently sloped and flat roofs have identical requirements. The existing LPS consists of the following: air terminals are locate within 2 feet of the upper and lower roof corners, air terminals are evenly spaced along the upper and lower roof perimeter, air terminals are evenly spaced along the midpoint of the upper and lower roofs, an air terminals is mounted exhaust fan and flue, for large exhaust fans two air terminals were used with one tying back to the LPS and the other to a ground rod penetrating the roof (that seems reasonable to assume it is connected to building steel), access ladders to both roof areas are bonded to the LPS. b. LPS Deficiencies and Government Required Corrective Action: Since this building exceeds 60 feet in height, an exterior ground ring is required. For the large exhaust fans, one of the air terminals that conductors route to a ground rod that penetrates the roof shall be removed. This conductor shall be tied back to the existing LPS. Refer to Drawing for existing and proposed LPS layout. This LPS shall be bonded back to the building main ground bar inside the Main Distribution Panel(s) of this building. 8) Building 105 Hazardous Material Pharmacy Operations Building: a.

Since this building does not exceed 60 feet in height, an exterior ground ring is not required. Refer to Drawing for existing and proposed LPS layout. This LPS shall be bonded back to the building main ground bar inside the Main Distribution Panel(s) of this building. 9) Building 117 Maintenance Shop Building: a. Existing Lightning Protection System (LPS) No LPS exists for this building. However, an existing antenna mounted on the roof and the existing gas meter has conductors that terminate to their own ground rod b. LPS Deficiencies and Government Required Corrective Action: Since the roof has a span of over 40 feet and the slope is 1/4 or greater, this roof is defined as pitched (in lieu of flat or gently sloped). Therefore, an LPS system shall be based on a pitched roof as prescribed in NFPA 780 which include but are not limited to the following protection: air terminal shall be within 2 feet of each roof top ridge edge, air terminals along roof top ridge with 20 feet maximum spacing, propose route down conductors from each top ridge edge down to bottom ridge edge and down the façade of the building to a grounding rod for each down conductor such that ground rods are at diagonal ends of the building, and an air terminal shall be added to the roof exhaust fan. Since this roof has multiple/intermediate ridges, additional protection will be required (i.e. additional down conductors and ground rods). Since this building does not exceed 60 feet in height, an exterior ground ring is not required. Refer to Drawing for existing and proposed LPS layout. This LPS as well as the antenna and gas meter grounding shall be bonded back to the building main ground bar inside the Main Distribution Panel(s) of this building. 10) Building 128 ASR (Airport Surveillance Radar) Building: a.

However, an existing antenna tower mounted at grade and the existing gas meter has conductors that terminate to their own ground rod. The existing tower is approximately 20'-4" away from the SW corner of the building. The existing tower's base is square and each side measures 32 inches and is 73 feet high with a platform at 53 feet high. There are two air terminals at the top of the tower at diagonal ends of the base. In addition, the gate near this building has been grounded and there is a ground test well near the NW corner of the building which seems to give evidence that a ground ring exists for this building and/or the tower. b. LPS Deficiencies and Government Required Corrective Action: Since the roof has a span of over 40 feet and the slope is 1/4 or greater, this roof is defined as pitched in lieu of flat or gently sloped. Therefore, an LPS system shall be based on this pitched roof as prescribed in NFPA 780 which include but are not limited to the following protection: air terminal shall be within 2 feet of each roof top ridge edge, air terminals along roof top ridge with 20 feet maximum spacing, and route down conductors from each top ridge edge down to bottom ridge edge and down the façade of the building to a grounding rod for each down conductor such that ground rods are at diagonal ends of the building. Since this roof has multiple intermediate ridges, additional protection will be required (i.e. additional down conductors and ground rods).

Please note that it is acceptable, since the exhaust fans are mounted at the roof's ridges that, these air terminals can serve as both ridge and mechanical unit protection. In addition, the existing gas meter and service entrance equipment have conductors that terminate to their own ground rod. b. LPS Deficiencies and Government Required Corrective Action: Some of the exhaust fans not mounted on the roof's ridge fall within the zone of protection (i.e. rolling sphere method) and require air terminals. An additional down conductor is required near the mechanical units that shall come down the façade of the building and terminate to a ground rod. Since this building does not exceed 60 feet in height, an exterior ground ring is not required. Refer to Drawing for existing and proposed LPS layout. This LPS shall be bonded back to the building main ground bar inside the Main Distribution Panel(s) of this building. 12) Building 154 Engineering Shop Building: a.

This LPS shall be bonded back to the building main ground bar inside the Main Distribution Panel(s) of this building. 14) Building 303 Wing Headquarters Building: a. Existing Lightning Protection System (LPS) No LPS exists for this building. However, an existing antenna tower and the existing gas meter have conductors that terminate to their own ground rod. b. LPS Deficiencies and Government Required Corrective Action: Since the roof has a span of over 40 feet and the slope is 1/4 or greater, this roof is defined as pitched in lieu of flat or gently sloped. Therefore, an LPS system shall be based on a pitched roof as prescribed in NFPA 780 which include but are not limited to the following protection: air terminal shall be within 2 feet of each roof top ridge edge, air terminals along roof top ridge with 20 feet maximum spacing, route down conductors from each top ridge edge down to bottom ridge edge and down the façade of the building to a grounding rod for each down conductor such that ground rods are at diagonal ends of the building, and an air terminal shall be added to each dormer if it is outside the zone of protection. Field dimensions of a typical dormer could not be measured but will need to be verified. Since this roof has multiple intermediate ridges, additional protection will be required (i.e. additional down conductors and ground rods). Since this building does not exceed 60 feet in height, an exterior ground ring is not required. Refer to Drawing for existing and proposed LPS layout. This LPS as well as the antenna tower and gas meter grounding shall be bonded back to the building main ground bar inside the Main Distribution Panel(s) of this building. 15) Building 560 RAPCON Building (Flight Radar Communication): a. Existing Lightning Protection System (LPS) For roof on the west end, there is only one air terminal on the west edge of the roof's ridge that is tied back to building steel and no visible down conductor was observed. For the roof on the east end, air terminals were observed at ends of each roof ridge and few intermediate air terminals were spaced between the roof's ridges. No down conductors were observed for the east roof. Since areas inside the building were not accessible and the ceiling had acoustical tile in lieu of being exposed, it seems reasonable to assume that these air terminals were bonded to building steel. The airfield tower roof has six air terminals, one at each building edge. The airfield tower roof is in the shape of a hexagon. The two vent pipes, roof hatch, guard rail at this roof, and the guard rail on the level just below are also bonded to this system. Since no down conductors were observed, it seems reasonable to assume that these air terminals were bonded to building steel. The existing generator and the existing gas meter have conductors that terminate to their own ground rod. b. LPS Deficiencies and Government Required Corrective Action: Since the roof on the east and west end have a span of over 40 feet and the slope is 1/4 or greater this roof is defined as pitched in lieu of flat or gently sloped. Therefore, an LPS system shall be based on this pitched roof as prescribed in NFPA 780 which include but are not limited to the following protection: air terminals on the west roof shall be added approximately 20 feet across the ridge of this roof, a few air terminals shall be added on the west roof to adequately cover the ridge of this roof. Since this air field tower exceeds 60 feet in height, an exterior ground ring is required. The absence of ground test wells was observed. Refer to Drawing for existing and proposed LPS layout. This LPS as well as the generator and gas meter grounding shall be bonded to the building main ground bar inside the Main Switchboard Panel. 16) Building 561: a. Existing Lightning Protection System (LPS) This building has an existing LPS that consists of the following: air terminals are installed within 2 feet of each corner of the pitched roof, air terminals are evenly spaced along the pitched roof's ridge, and at each of the four corners of the building down conductors are routed down the façade of this building; conductors are protected by PVC conduit from midway of the building to a ground rod. Near the top of the down conductor, the conductor was tapped and bonds to building steel. The absence of test wells was observed. b.

LPS Deficiencies and Government Required Corrective Action: Please note that for roof top mechanical units, air terminals shall be 2 feet maximum from a corner or edge and shall be 20 feet maximum between air terminals. Since the exhaust fans are over 48 inches in diameter, 3 or 4 air terminals are required. The cooling tower has 1 or 2 air terminals, but 4 air terminals are required. Since the condensing units are over 48 inches in length, 2 air terminals are required. A few air terminals are missing at the corners of the flat roof. Additional mid-roof air terminals may be required to ensure the roof's zone of protection but would need further investigation if re-designed. Since this building does not exceed 60 feet in height, an exterior ground ring is not required. Refer to Drawing for existing and proposed LPS layout.

Existing Lightning Protection System This building has an existing LPS that consists of the following: air terminals are installed within 2 feet of each corner of the multiple flat roofs, air terminals are evenly spaced along the flat roof perimeter and roof ridges, and down conductors are located at the midpoint on the east and west sides that route protected by PVC conduit down the façade of the building and terminate to a ground rod. b. LPS Deficiencies and Government Required Corrective Action: The mid-roof air roof terminals exceed 20 feet maximum spacing. Therefore, either the air terminals (lower than 24 inches) need to be added and/or re-spaced or air terminals (24 inches or higher) need to be replaced in the same location. Since this building does not exceed 60 feet in height, an exterior ground ring is not required. Refer to Drawing for existing and proposed LPS layout. This LPS shall be bonded to the building main ground bar inside the Main Switchboard Panel, Which is surface mounted to the east face of this building, the absence of the existing LPS tied to the main panel ground bar was observed. 29) Building 898 Administration and Trailer Maintenance: a. Existing Lightning Protection System This building has an existing LPS that consists of the following: air terminals are installed within 2 feet of each corner of the multiple pitched roofs, air terminals are evenly spaced along the ridge of each roof, air terminals are evenly spaced east and west ends of each curved canopy, ground test wells are located at the south side and NW area of the building, and the absence of down conductors was observed which seems reasonable that the LPS was tied back to building steel. In addition, the existing gas meter has a conductor that terminates to a ground rod. b. LPS Deficiencies and Government Required Corrective Action: Since this building does not exceed 60 feet in height, an exterior ground ring is not required. There are no known deficiencies, refer to Drawing for existing LPS layout. 30) Building 899 Storage Igloo Building: a. Existing Lightning Protection System This building has an existing LPS that consists of the following: air terminals are installed on the earth covered ridge; two air terminals are installed on concrete piers on top and at the front of this building; an air terminal is installed for each of the two exhaust fans at the back of the building, and a down conductor for each of these exhaust fans routes down its concrete pier support and disappears into the earth. It seems reasonable that these air terminals are tied back to building steel. b. LPS Deficiencies and Government Required Corrective Action: One of the air terminals on the exhaust fans are not pointing straight up due to rim of the exhaust fan is bent. Our recommendation is to re-mount this air terminal to the top of the exhaust fan. Based on distance of the earth covered ridge, about two more air terminals need to be added to the ridge of the building. Since this building is covered with earth on three of its four sides, further investigation (i.e. existing as-build drawings) may be needed for air terminal placement. Refer to Drawing for existing and proposed LPS layout. This LPS shall be bonded to the building main ground bar inside the Main Switchboard Panel. 31) Building 1408 are JRIC (Joint Reserve Intelligence Center) Detroit Building: a. Existing Lightning Protection System This building has an existing LPS that consists of the following: air terminals are installed within 2 feet of each corner of the two flat roofs, air terminals are evenly spaced along the perimeter of each roof, both access ladders from grade to lower roof and from lower to upper roof are grounded to the LPS, the antenna on the rear of the building is bonded to the LPS, air terminals exist on the rooftop air handling unit as well its piping support structure; each roof drain is bonded to the LPS, and there are two down lead conductors protected in PVC conduit for its entire length that are located on the east and SE sides of the building that seem to terminate at a ground rod. The absence of air terminals was observed for condensing units and an exhaust fan but seem to fall under the zone of protection of the existing air handling unit and upper roof respectively. In addition, the existing gas meter has a conductor that terminates to a ground rod. b. LPS Deficiencies and Government Required Corrective Action: Each air terminal has a rounded top which seems to reduce the effectiveness of protection. We recommend removing these rounded tops if possible. If removing each top is not possible, we recommend replacing these air terminals in kind. One of the air terminals on the SE corner does not point straight up and needs to be adjusted and/or re-supported. Roof drains do not require protection but can be left in place. Refer to Drawing for existing and proposed LPS layout. This LPS shall be bonded to the building main ground bar inside the Main Switchboard Panel. 32) Building 1416 Army Aviation Support Facility #2 Building: a. Existing Lightning Protection System This building has an existing LPS by Guardian Equipment Company that consists of the following: air terminals are installed within 2 feet of each corner of the multiple flat roofs, air terminals are evenly spaced along each flat roof perimeter, air terminals are evenly spaced on mid-roof at the high roof, few of the mechanical equipment have air terminals, the lower roofs have conductors between and are bonded to each air terminal and were bonded to building steel; the high roof the absence of conductors were observed and seems reasonable that each air terminal or group of air terminals are bonded to building steel; each access ladder were bonded to the LPS, and building mounted antennas were bonded to the LPS. In addition, an existing antenna mounted at grade has conductors that terminate to a ground rod. b. LPS Deficiencies and Government Required Corrective Action: The majority of mechanical equipment and flues that fall under the zone of protection requires air terminals. Some conductor connections are disconnected or frayed and need to be repaired. A conductor is disconnected to a floor drain and should be removed. Since this building exceeds 60 feet in height, an exterior ground ring is required. The absence of ground test wells was observed. Refer to Drawing for existing and proposed LPS layout. This LPS shall be bonded to the building main ground bar inside the Main Switchboard Panel. 33) Building 1417 ASR (Airport Surveillance Radar) Building: a. Existing Lightning Protection System No LPS exists for this building b. LPS Deficiencies and Government Required Corrective Action: Since the roof has a span of 40 feet or less and the slope is 1/8 or greater, this roof is defined as pitched in lieu of flat or gently sloped. Therefore, an LPS system shall be based on this pitched roof as prescribed in NFPA 780 which include but are not limited to the following protection: air terminal shall be within 2 feet of each roof top ridge edge and route down conductors from each top ridge edge down to bottom ridge edge and down the façade of the building to a grounding rod for each down conductor such that ground rods are at diagonal ends of the building. Since this building does not exceed 60 feet in height, an exterior ground ring is not required. Refer to Drawing for existing and proposed LPS layout. This LPS shall be bonded to the building main ground bar inside the Main Switchboard Panel. 34) Building 1422 (Hanger Maintenance Building): a. Existing Lightning Protection System This building has an existing LPS by Guardian Equipment Company consisting of the following: air terminals are installed within 2 feet of each corner of the two gently sloping roofs, air terminals are evenly spaced along the perimeter of each roof, the access ladders from lower roofs to upper roofs are grounded to the LPS, the access hatch was bonded to the LPS, the multiple antennas mounted to the side of the upper roof are bonded to the LPS, air terminals are installed at each exhaust fan, all of the mechanical units have some air terminals installed, and the LPS is connected to building steel at multiple locations. In addition, the existing gas meter has a conductor that terminates to a ground rod. b. LPS Deficiencies and Government Required Corrective Action: Since many of the mechanical units (i.e. RV units) are over 48 inches wide, they would require four in lieu of one or two air terminals. Refer to Drawing for existing and proposed LPS layout. This LPS shall be bonded to the building main ground bar inside the Main Switchboard Panel. 35) Building 1515 Department of Homeland Security Operational Integration Center: a. Existing Lightning Protection System This building has an existing LPS that consists of the following: air terminals are installed within 2 feet of each corner of the two flat roofs, air terminals are evenly spaced along each flat roof perimeter, the majority of mechanical units have adequate air terminal protection, antennas on the roof were connected to the LPS, and down conductors protected by PVC conduits were routed down the back façade of the building to a ground rod. In addition, a tower at grade near the building and the existing gas meter had conductors terminating to a ground rod b. LPS Deficiencies and Government Required Corrective Action: The cooling tower should have four air terminals in lieu of one such that each air terminal is no more than 2 feet from the edge of the equipment. Refer to Drawing for existing and proposed LPS layout. This LPS shall be bonded to the building main ground bar inside the Main Switchboard Panel. 36) Building 1572 Warehouse Supply & Equipment BSE Building: a. Existing Lightning Protection System: The LPS for this building consists of two air terminals mounted on the upper roof that route to a down conductor to a ground rod. These air terminals do not point up and the conductor between these air terminals is not supported properly b. LPS Deficiencies and Government Required Corrective Action: The LPS system shall be based on this flat roof as prescribed in NFPA 780 which include but are not limited to the following protection: air terminal shall be within 2 feet of each upper and lower roof corner, an intermediate air terminal shall be proved for each side of the upper roof, for the upper roof only route one down conductor from roof top down to the façade of the building to a grounding rod, and the existing down conductor at the diagonal end of the building can be reused. Two of the existing air terminals can be reused but shall be re-mounted to point up and the conductor between these air terminals needs to be re-supported. Since this building does not exceed 60 feet in height, an exterior ground ring is not required. Refer to Drawing for existing and proposed LPS layout. This LPS shall be bonded to the building main ground bar inside the Main Switchboard Panel. 37) Building 3570 ASR (Airport Surveillance Radar) Building: a. Existing Lightning Protection System This building has an existing LPS by Thompson Lightning Protection, Inc. that consists of the following: a ground bar that ties into the main ground bar inside the building located on the back of the building bonds to large metallic straps with isolation bars and two cable entry ports, an exterior transformer is bonded to ground, internal building ground bars penetrate the wall of the building and appear to bond the LPS; and a ground test well is located between the building and the radar tower and it seems reasonable to assume that there is an existing ground loop for this building. In addition, the radar tower and all associated metallic components and air terminals are bonded to the LPS. The supporting generator enclosure has a ground test well next to it that is bonded to its exterior building conduits and to the service entrance ground. Refer to Appendix A for existing and proposed LPS layout. This LPS should be tied together back to the building main ground bar which is assumed to be inside the Main Panel of this building. b. LPS Deficiencies and Government Required Corrective Action: Air terminals are missing from the roof of the building due the rolling sphere method from the radar tower to this building. Air terminals shall be 2 feet from each corner. LPS shall be bonded to the building main ground bar inside the Main Switchboard Panel. 38) Building 3572 / 3573 ASR (Airport Surveillance Radar): a. Existing Lightning Protection System This building has an existing LPS that consists of the following: air terminals are installed within 2 feet of each corner of the pitched roof, a mid-roof air terminal is located on the pitched roof, down conductors are routed down the façade of the building to ground rods, two future cable ports at the back of the building are bonded and conductors are routed down the façade of the building to what is reasonable to assume a ground rod. In addition, for the tower next to the building the down conductors are routed down the tower and are coiled at both ends for future connection since the radar tower is not completely constructed. LPS Deficiencies and Government Required Corrective Action: This building is not fully constructed. The radar tower will need air terminals at the top and shall bond to all metallic components (i.e. stairs). Once the electrical service is installed at tower, LPS and other grounding systems (i.e. generator) can be bonded together at the service entrance. Refer to Drawing for existing and proposed LPS layout. This LPS shall be bonded to the building main ground bar inside the Main Switchboard Panel.
