STATEMENT OF WORK

PROJECT TITLE: REPAIR AIRFIELD PAVEMENT PADS Phase 2

PROJECT # KELL 90-5421A;

WORK ORDER # 44797;

LOCATION: Joint Base San Antonio Lackland’s Kelly Runway

1.0 PROJECT SCOPE

1.1 BACKGROUND

JBSA-Lackland’s Kelly Airfield (Figure 1) has only one runway. Major expansion of the airfield was conducted during the early 1940s. In the mid-1950s, Runway 15- 33 was constructed and the airfield was expanded to its present-day configuration. In some cases, World War II-era or earlier pavements were overlaid with additional concrete to achieve final thicknesses and elevations. Since the 1950s, airfield pavements have been removed and replaced, overlaid, or repaired. Substantial repairs to the runway keel sections occurred in the late 1980s. Apparently, airfield construction records were not transferred to Lackland AFB when the real property was transferred in 2001. Runway 15-33 will go through a name change in 2015 of 2016 to Runway 16-34. JBSA-Lackland’s 15/33 runway is an 11,550 foot long runway with 12 taxiways and 4 aprons and 2 arm/disarm pads. It is open 24 hours a day 7 days per week. All Kelly Airfield closures shall be negotiated prior to award of this contract.

Figure 1: Project Location JBSA-Lackland’s Kelly Airfield

1.1.1 Work site existing conditions: JBSA-Lackland’s Kelly Airfield: has a variety of slab sizes. The slabs to be repaired are of varying size, location, age and condition. See Core Map located in Appendix F. The soil is very expansive clay and due to the amount of rain we have been having this year (2015), we have learned that on occasion once the slabs are removed the void fills with water. Also, when it rains the void holds water and does not drain even after days of sitting. Contractor may have to pump rainwater from excavated areas and let the void sit for several days in order for base rock compaction to be achieved.
