The Authority initiated this study in partnership with Joint Base San Antonio (JBSA), Operations Support Squadron (OSS), the 502nd Civil Engineering Squadron (CES) and the Air Force Civil Engineer Center (AFCEC) to determine a long‐term solution to eliminate extended runway closures at SKF. This study has been partitioned into two parts. Part I evaluates the existing pavements and endeavors to answer two questions: 1.) Does the pavement require full reconstruction or can future M&R‐type projects address the pavement needs, and 2.) At what point in the future is it required. Part II endeavors to explore and conceive optional courses of action (COA) for construction activities on Runway 16‐34. CHA Consulting, Inc. (CHA) has been retained by the Authority to evaluate, strategize, and recommend opinions of existing pavement condition, address the prominent questions, and recommend construction sequencing strategies which promote minimization, or altogether eliminate, extended runway closures. In March 2017, Part I of this study was presented with general recommendation to pursue full reconstruction of the inner 75’ of roughly 9,000’ of runway. This inner section, referred to as the keel section, exhibits an average pavement condition index (PCI) of 51 based on a 2012 PCI Study provided by AFCEC. AFCEC in conjunction with the 502nd CES has programmed an update to the 2012 PCI Study for some time during the 2017 calendar year. This update is considered critical as it relates to understanding the impacts (good or bad) of the 2016 M&R project. As an aviation industry standard, PCI values below 65 for a runway (60 for a taxiway) typically points to an invasive rehabilitation, but often times full reconstruction. However, AFCEC uses a slightly different scale to determine the level of M&R as well as reconstruction. A PCI value between 50 and 70, according to AFCEC, means continued major M&R (i.e. isolated panel replacement, joint sealant replacement, spall repair, etc. for concrete pavements); whereas, pavements with a PCI below 50 will then be looked at closer to determine the severity of the pavement distresses and the timeline for which reconstruction may occur. PCI values alone do not always make a definitive direction of a pavement project. Funding and available annual allocations, whether military or civilian sourced, can often times mold the definition of a pavement project. In this case, because the USAF owns and operates the flying facilities at SKF, pavement repair and/or reconstruction would most likely be funded through the United States Department of Defense (DoD) through its military construction (MILCON) program. No different than the Federal Aviation Administration (FAA), while PCI values can justify a project’s eligibility for funding, it also must outrank other facilities in the system for priority. As such, in July 2017, AFCEC and the 502nd CES notified the Authority that the 2017 PCI Study has revealed a significant increase in PCI values for Runway 16‐34, rising from 51 to 64 on average. While Part I of this study recommends reconstruction of the keel section, the USAF intends to continue its major M&R program for Runway 16‐34. The next project is programmed for design in fiscal year (FY) 2019, with construction planned for FY2021. 1 of 32 Alternative Landing Surface Analysis Part I ‐ Final Report September 2017 REPORT A. INTRODUCTION Kelly Field is a joint use (military/civilian) airfield located on the southwest side of San Antonio at the former Kelly Air Force Base (AFB) site. The United States Air Force (USAF) owns and operates the runway, taxiways, Air Traffic Control Tower (ATCT), Aircraft Rescue and Fire Fighting (ARFF) facility, navigational aids, instrument approaches, and associated systems (the Flying Facilities). It manages the jointly used Flying Facilities through its 502nd Operations Support Squadron (OSS). Military use of Kelly Field includes the USAF hosting flight operations of two tenant commands, the Air Force Reserve’s 433d Airlift Wing, operating the C‐5 Galaxy, and the Texas Air National Guard’s 149th Fighter Wing, operating the F‐16 Falcon. Civilian use of Kelly Field is provided by the Port Authority of San Antonio who has a Joint Use Agreement (JUA) with the USAF for the public civilian use of the Flying Facilities, and who owns adjacent land and facilities dedicated to civilian aviation use. The Port Authority of San Antonio (Authority) is a Texas defense base development authority charged with managing the conversion of portions of the former Kelly AFB to civilian use, while promoting economic health through the attraction and preservation of industry and associated jobs. The 1,900 acres of Kelly AFB property that was transferred to the Authority is now known as Port San Antonio (PSA) which is directly adjacent to the portion retained by the USAF and is officially known as Kelly Field Annex (KFA). Of those 1,900 acres, approximately 640 acres are dedicated to aviation use. The Authority owns and operates exclusive‐use ramp, hangars, and facilities occupied by civil operators; leaseback ramp, hangars, and facilities occupied by the USAF; a public‐use ramp; a fuel farm; connector taxiways; and a variety of buildings and hangars currently marketed to the civil aviation community. Collectively, the Flying Facilities and the PSA land dedicated to aviation use represent the airport referred to as Kelly Field. The three letter airport identifier for Kelly Field is SKF. As a public civil aviation use airport, the Federal Aviation Administration (FAA) has added SKF to its National Plan of Integrated Airport Systems (NPIAS), and the Texas Department of Transportation Aviation Division (TxDOT) has also included SKF in its Texas Aviation System Plan (TASP). These inclusions validate SKF’s role as part of a state and national network of airports serving civil aviation needs. B. PROJECT BACKGROUND SKF has a single runway (Runway 16‐34, formerly named Runway 15‐33) that has been in place since 1955. The pavement condition of some of the older concrete sections is deteriorating and may need significant reconstruction or repairs in the foreseeable future. The Authority is concerned of the hardship to its customers should significant runway closures be required for pavement maintenance, repairs and/or reconstruction. It is recognized that long runway closure periods would likewise cause hardships to the military by requiring deployment of its commands. Page 2 of 32 Alternative Landing Surface Analysis Part I ‐ Final Report September 2017 CHA Consulting, Inc. (CHA) has been retained by the Authority to evaluate the existing runway and parallel taxiway pavements (Taxiway A), to determine likely future rehabilitative measures that will be required, and to provide recommendations on how best to mitigate runway closure times for accomplishing the work. CHA is supported by two (2) local consulting firms: Pape‐Dawson Engineers and Arias Geoprofessionals. Collectively, this team is referred to as ‘CHA’ in this report. CHA has been coordinating its efforts closely with the Authority, and the USAF including OSS, the 502nd Civil Engineering Squadron (CES) and the Air Force Civil Engineer Center (AFCEC). There are two parts to this study. This Part I Report evaluates the existing pavements, determines the areas
