About this file
This document is a Lightning Inspection Building 119 checklist that details the visual inspection and testing requirements for a lightning protection system. The checklist covers the inspection of roof top components, the ground system, and ground resistance and continuity testing. It includes specific details such as the spacing and placement of air terminals, the interconnection of cables, and the condition of bonding and grounding connections. The document also includes additional notes with detailed ground resistance readings taken at various test points on the system.
The related federal contract opportunity is for the Repair of Lightning Protection Systems, which is being solicited as a Total Small Business Set-Aside with a NAICS code of 238210 and a size standard of $19.0M. The project is expected to be between $25,000.00 and $100,000.00, and Davis-Bacon Wage Rates apply. Payment bonds are required if the bid is greater than $35,000.00, but performance bonds are not required if the bid is less than $150,000.00. The award will be made to the responsible bidder whose bid is most advantageous to the Government, considering only price. Funds are anticipated to be available prior to but not later than midnight 30 Sept 2024. LPS Inspection Reports are attached for reference.

Date: _______11/8/23________ Inspected and Tested By: __MVS (Jesse, Dustin, Lumuli)________ Structure/Building Identification: ________119_________________________ Date Last Known Rainy Day: ____11 days__________ Humidity: ___1%______________________
A. Visual Inspection of Roof Top Components
3923 S. TAVISTOCK PL. || MERIDIAN, ID 83642
Item Descriptions Notes/Correction
1 Visual inspections of the overall system condition.
Appearance (neat, dislodged, broken cables etc.).
One cable frayed on west facing wall.
2 Visually inspect all air terminals. Verify that size and quantity is sufficient per NFPA 780/UL96A requirements.
3 Verify that all air terminals (lightning rods) have been placed at 20’-0” maximum spacing around roof perimeter and/or roof ridges.
4 Verify that perimeter air terminals are within 2’-0” of the outside edge including corners of the structure.
5 Verify that mid-roof air terminals are spaced at maximum spacing of 50’-0” in accordance with NFPA 780.
6 Verify interconnecting mid-roof cables connecting mid-roof air terminals are properly spaced. Further verify 150’-0” maximum length of cross run conductor to the main perimeter or down conductor in accordance with NFPA 780.
7 Verify that copper materials are not mounted or in contact with aluminum materials and vice-versa.
8 Verify that all conductors are fastened horizontally and vertically not more than 3’-0” maximum spacing.
9 Verify inductive metallic bodies located within 6’ 0” of lightning conductor or another bonded metal body shall be interconnected to the lightning conductor system, unless inherently connected.
10 Verify air terminals and bonding connectors are installed on rooftop, fans, ventilators. A/C units etc. in accordance with NFPA 780 UL96A.
11 Remove and clean all cable connections including but not limited to; Bonding plates, lugs, cable to cable connectors etc.
B. Visual Inspection Ground System:
C. Ground Resistance & Continuity Testing:
Item Descriptions Notes/Correction
1 Locate all through roof connection to down runs or to structural steel. Visually inspect for damage and tightness.
2 Verify the quantity of down runs/connection to ground is adequate per NFPA 780 and UL96A based on the size of the structure.
3 If the connection is to steel, verify that connection is made in accordance with NFPA 780 and that the area under connection is clean of all paint, oil, grease etc.
4 Verify that spacing of down conductors at roof level are installed in accordance with NFPA 780 and UL96A (100’ on average).
5 Visually inspect connections to rebar/structural steel etc. for corrosion remove connections clean and reinstall. Replace if necessary.
6 Visually inspect ground rods and cable connections to ground rods. Remove and clean if necessary.
Item Descriptions Notes/Correction
1 Record the device readings for all tested points: See Additional Notes
2 Inspect and document status of surge protection - transient voltage surge suppression (TVSS) systems. Verify TVSS systems are installed in accordance to NEC 70 or other applicable codes or standards.
N/A
Perform ground resistance on lightning protection grounding system.
See Additional Notes
3 Take additional photographic or video documentation of particular areas of the lightning protection system that needs further long term repair that may go beyond the scope of this inspection but needs attention.
