Intersection of Runways 10-28 &15-33L at BWI Airport

Location: Anne Arundel County, Maryland Client: Maryland Aviation Administration

JMT provided program management services to the Maryland Aviation Administration to craft a comprehensive program that addressed the federally stipulated runway safety area compliance mandate.

The Maryland Aviation Administration (MAA) selected JMT to provide comprehensive program management services for the $350M BWI Thurgood Marshall Airport Runway Safety Area (RSA), Pavement Management and Standards Compliance Program. The RSA portion of this program is required for compliance with the Federal Runway Safety Area Compliance Mandate that stipulates all commercial airport runways must meet FAA standards for Runway Safety Area (RSA) dimension, grading, and frangibility by the end of 2015.

In order for BWI Thurgood Marshall Airport to adhere to the Federal RSA compliance mandate, JMT assisted MAA in crafting a comprehensive program that not only addressed the airport's RSA deficiencies but simultaneously addressed required pavement rehabilitations and non-standard airfield conditions.

Through this program, all airfield needs could be simultaneously and efficiently addressed in a short period of time, while minimizing traveler disruption by maximizing the scope of work accomplished during any given runway or taxiway closure.

JMT's approach to the project started with a review of the applicable studies performed and understanding that sweeping airfield improvements could not be implemented unilaterally, JMT assisted MAA by preparing and conducting a series of briefings with all stakeholders including the FAA, regulatory agencies, airlines and MAA operations staff that were intended to present possible component projects and construction project phasing scenarios to facilitate a broad consensus on a preferred project approach.

Having achieved the necessary consensus on the overall program, the first project undertaken was the pavement rehabilitation and standards compliance improvements to the intersection of Runways 15R-33L and 10-28. This once-in-a-generation project was complex even by airfield design standards. With both runways scheduled to undergo geometric modifications in future years -- Runway 15R-33L shortened and offset by three feet and Runway 10-28 narrowed -- existing and future geometry needed to be accounted for in the design and all new runway lighting infrastructure had to be installed.

To achieve the project goals, coordination with the airlines serving BWI was continuous, with JMT coordinating the modeling of airfield activity and delay in support of MAA Planning staff and presenting the findings to representatives of the airlines and FAA.

To facilitate efficient construction, JMT assisted MAA in demonstrating to the stakeholders the benefits of expanding preparatory overnight runway work hours from the airport's standard three-hour window to a seven-hour window, and the need to use Runway 4-22, a 6000 foot non-instrumented and seldom-used runway, to maintain operations and help facilitate the longer overnight working windows. The eventual success of the intersection project hinged on all parties agreeing to this plan of action and adjusting their operations accordingly.

Even with the expanded night time work hours, a long duration, one-time intersection closure was necessary to accomplish the pavement resurfacing and re-profiling work. To address this need, JMT assisted MAA in achieving stakeholder consensus on a 54-hour period of continuous closure of both runways. The closure was scheduled almost a year in advance of the closure for September 2011 with an alternate period the following week to allow the airlines to adjust flight schedules and plan for repositioning aircraft. As a result of these efforts, the project was delivered at a savings of approximately 50% when compared to the traditional methods of construction for runway intersections.
