About this file
This is a technical test results and drawings document containing lightning protection system measurements and inspections conducted at Fort Leavenworth, Kansas during March and April 2022. The document presents detailed resistance measurements (in milli-ohms) for air terminals across 13 buildings, along with architectural drawings and test result tables. Inspections were performed on Buildings 52, 102, 132, 286, 314, 336, 399, 466, 467, 472, 474, 1156, and 1157 at various Fort Leavenworth addresses including Sherman Avenue, Meade Avenue, Chief Joseph Loop, Sedgwick Avenue, Thomas Avenue, Sheridan Drive, and Harrison Drive. The measurements document the condition of existing lightning protection systems, identifying issues such as loose air terminals, loose clamps, missing fasteners, open-circuited terminals (marked as "OPEN" in tables), and absent terminals (marked as "NO AT"). Notable findings include several terminals with high resistance values exceeding acceptable thresholds, such as Building 52 terminal 71 at 72.100 milli-ohms and Building 286 terminal 5 at 30.410 milli-ohms, indicating potential deficiencies in grounding continuity.
The inspection work was conducted across two site visits due to inclement weather during the initial March 28-April 1, 2022 trip, with follow-up measurements completed April 25-26, 2022. Each building section includes comprehensive drawings showing the locations of air terminals, ground rods, downs, thru-roof connections, and cable routing, supplemented by resistance measurement tables correlating terminal numbers to recorded values. This technical documentation serves as baseline data for the Army's lightning protection system installation, inspection, testing, and repair solicitation W91QF4-26-B-A013, with a scheduled site visit for perspective bidders on August 25, 2026, at 10:00 AM CST at Fort Leavenworth to review these systems and discuss required remediation work.

INTRODUCTION
1 Introduction
• Many loose air terminals, loose clamps, and missing fasteners were observed. Some terminals provided resistance measurements and some were open circuited. Open circuited terminals are marked as such in the measurement tables.
• Every attempt was made at maintaining due diligence.
• Fort Leavenworth was visited to make measurements: from Monday, March 28th, 2022 through Friday, April 1, 2022, and on Monday, April 25 and Tuesday, April 26, 2022.
• We experienced inclement weather throughout most of the initial trip.
• On the second trip, our staff had to deploy tractor cones to keep cars from blocking the area(s) where the boom lift needed to operate.
INTRODUCTION
Nomenclature:
• Numeric value “0.343”, etc. = meter reading, in units of milli-ohms.
• “NO AT” = No air terminal present at the indicated location.
• “OPEN” = open circuit, no measured continuity.
