John Glenn International Airport

JOHN GLENN COLUMBUS INTERNATIONAL AIRPORT

2 The Columbus Regional Airport Authority (CRAA) selected CHAExhibit from their list of Runway 10L-18R Relocation prequalified consultants to prepare documentation to define the scope of work and RPZ Shift to provide budgetary program cost estimates for services required to relocate Runway 10L-28R to the north a minimum of 50 feet. The separation distance between Runway 10L‐28R to parallel Taxiway ‘E’ at John Glenn Columbus International Airport (CMH) is 350 feet. The standard separation distance based on FAA design criteria is 400 feet. Therefore, the CRAA has an approved modification to FAA standards (MOS) for this condition. As part of the MOS documentation an alternative to relocate Runway 10L‐28R to the north a minimum of 50 feet was required.

The analysis consisted of planning and design engineering for land acquisition, demolition, pavements, drainage modifications, airfield lighting modifications, and navigational aid modifications required to relocate Runway 10L-28R 50 feet to the north. The effort used documents provided by CRAA (airport layout plan, property maps, record drawings for Net Jets Corporate Hangars, record drawings for Runway 10L‐28R rehabilitation and record drawings for associated taxiways and connectors). The preliminary scope of work for this alternative included the following major components: ALP update, EA/EIS, land acquisition, design engineering, and construction. The major construction items identified are:

•• Runway 10L‐28R, and Taxiway ‘F’ relocations (pavements, lighting, signing, and marking) •• Exit and entrance taxiway relocations and adjustments (pavement, lighting, signing, and marking) •• Storm water management (detention, inlet and pipe modifications, including north ditch relocation/additional piping) •• Navaid relocations (localizers, glide slopes, approach lighting, RVR, and PAPI’s) •• RPZ land acquisition •• RPZ land use compliance – excluding road relocations The CRAA used the scope and estimate provided for this alternative to support the renewal of the Modification to Standards for runway to parallel taxiway separation distance.

Crossover Taxiway

John Glenn International Airport CHA was responsible for design of the taxiway and bridge structures, utility relocations, cost estimating, safety and phasing coordination, and construction administration, inspection, and testing at Port (John Glenn) Columbus International Airport (CMH). This project included the construction of a new connector taxiway (1,900 ft x 75 ft) between CMH’s two runways. The new taxiway crosses the airport’s new primary entrance road, (relocated International Gateway). The relocated International Gateway includes seven vehicular traffic lanes and two light rail transit tracks. The taxiway bridge structure spans 185.5 ft and is 217 ft wide. The bridge was designed to accommodate large, heavy aircraft. The taxiway eases aircraft congestion on the east side of the airfield and also provides the needed runway access for the proposed new Midfield Terminal project. Also included in this project were two roadway bridges. One bridge (188.5 ft span and 74 ft wide) accommodates the new airfield perimeter road and a new parking lot access ramp. The second roadway bridge (187 ft span and 29.5 ft wide) is used for the terminal circulation. The project was phased over several years and was coordinated with the new International Gateway/Stelzer Road interchange and the new Midfield Terminal development. Lessons Learned: •• Validate design criteria with airport planning efforts at the start of a major project •• During construction, confirmation was required of construction layout with design drawings particularly for major work items •• Aesthetics in engineering have an important role in highly visible public projects

The navaids development included: •• Upgrade of an existing military GRN-29 ILS to civilian Category II status with new ALSF-2/SSALR, RVRs, control cable network, touchdown zone lighting, Runway 05R, and airfield vault improvements •• Upgrade of an existing military GRN-27 ILS to civilian Category I status including the installation of an outer marker locator, and MALSR approach lighting (Runway 23L) •• Installation of in-pavement touchdown zone and centerline lighting •• Part 77 obstruction survey and analysis, consultation with FAA, Air Force, and equipment manufacturers •• Approach procedure analysis was used to avoid noise sensitive areas Coordination during construction provided safe operations could be maintained throughout the program — particularly during the touchdown zone and approach lighting phase.

Pavement Management Program Rickenbacker International Airport

A comprehensive pavement management study was conducted at the Rickenbacker International Airport in an effort to evaluate existing pavements at various locations on the airfield. The findings of the report served as a guideline for implementing a Pavement Management Program over the next fifteen years. The primary objective of the study was to evaluate the functional and structural pavement condition of the existing airfield facilities, and to develop and prioritize rehabilitation strategies. The report presented the findings of the investigative efforts and offered rehabilitation/maintenance recommendations based on pavement design and cost analysis for each pavement facility. The first phase of the study consisted of non-destructive testing (NDT) and a pavement condition survey. Pavement coring and materials analyses were performed to confirm or deny the presence of durability cracking distresses in the concrete pavements. Based upon the results of these pavement studies, the rehabilitation/maintenance priorities of the airfield pavements were analyzed in terms of their functional conditions, structural conditions, and remaining lives. Short-term versus long-term rehabilitation alternatives were evaluated to determine the most cost-effective approach for rehabilitating the pavement of each facility. A 15-year plan was prepared for scheduling pavement rehabilitation or reconstruction of the various airfield facilities at the Rickenbacker International Airport. #

Runway 4-22 Rehabilitation Bolton Field Airport This project involved the rehabilitation of the airport’s 5,200 ft by 100 ft runway, the installation of 20 airfield guidance signs, and the relocation of the localizer antenna and shelter. The rehabilitation consisted of pulverizing, shaping, and compacting the existing 4” of asphalt in place and the construction of a new 4-inch P-401 asphalt surface over the recycled subbase. The rehabilitation was coordinated with the 300 ft runway extension. The project required the runway rehabilitation work to be constructed during a fasttrack time period of 10 consecutive calendar days. The parallel taxiway was utilized as a temporary runway for Group B-II (or smaller) aircraft. CHA was responsible for the surveying, geotechnical investigation, preliminary and final design, plans and specifications, bidding assistance and construction services.
