Lackland AFB is home to the 433rd Airlift Wing, the 149th Fighter Wing, Boeing’s San Antonio Maintenance Center and serves as a key training airfield for AETC aircraft based at nearby Randolph AFB. The project involved the design and replacement of the failing and non-standard threshold light system at each runway end and an electrical distribution transformer serving vital navigation aids. Although a design-build project, a comprehensive approach was taken in meeting the project objectives. As a result, a number of non-standard and hazardous conditions were identified on the airfield and additional airfield improvements were made which added no additional cost to the project. An assessment of the airfield lighting system has been conducted to identify future SR&M projects to continue on a program to enhance airfield safety and sustainability. This assessment will serve as an Asset Management tool for programming future projects when funding opportunities arise or the base mission dictates.
