Parsons and the City of Cleveland won the 2003 American Road & Transportation Builders Association Globe Award for environmental excellence. This award is given for projects that demonstrate excellence in environmental protection, mitigation, and enhancement through the planning, design, and construction of U.S. transportation infrastructure projects.
The entire EIS planning process for the new runway
was completed within 29 months, far shorter than the more typical 10 years,
using the FAA’s Expedited Airport System Enhancement (EASE) initiative.
A total of 3.8 million cubic yards of earth will be moved during the Abram Creek relocation project. |
Cleveland Hopkins International Airport is surrounded—by the Rocky River Reservation Park and gorge to the south and west, Highway I-480 and State Route 17 to the north, NASA Glen Research Center to the west, and State Route 237 and Ford Motor Engine and Assembly Plant to the east—and therefore cannot expand its territory. However, in 1997, Cleveland Airport realized it had to increase capacity to meet 21st century travel demands. Most important, the airport needed a new parallel runway sufficiently separated from other runways to facilitate electronically aided simultaneous takeoff and landing operations. Parsons entered into a joint venture partnership called the Program Management Team (PMT) as the lead partner in March 1998 to assist in managing the design and construction of New Runway 6L-24R. Over 20 projects were identified to overcome the many obstacles facing the construction of this new runway in an existing area. The entire project is scheduled for completion in December 2004, with the possibility of a two-year extension. During its first 29 months, the project focused on airport planning, environmental studies and permits, fund-raising, and detailed cost and schedule analysis. Many property issues had to be resolved to make the new runway and its surrounding safety zones work with neighboring land uses. In fact, it required an act of Congress to acquire the additional property needed for easements from NASA, local business owners, local homeowners, the City of Brookpark, and Cleveland Metroparks. Extremely sensitive environmental issues arose because most of the operating airport property discharges into several nearby streams or into the Rocky River. With help from northeast Ohio’s Congressional delegation and Ohio Governor Robert Taft’s office, the Department of Port Control (DPC) and PMT secured a waiver of the Clean Water Act water quality certification from the Ohio EPA and obtained U.S. Army Corps of Engineers authorization to construct the new runway while observing extremely rigorous and precedent-setting environmental controls. In exchange, the city agreed to preserve or restore 30,000 feet of streams and over 300 acres of wetlands in and around Cleveland. The EPA’s and the Corps’ strict criteria required $26 million in onsite environmental protection and cleanup work and $31 million to remediate local wetlands and streams. No other airport project has ever had to meet criteria this strict. DPC and the Parsons-led JV integrated complex financial packaging with funding sources from federal, state, local, and user communities involving a federally backed $149 million letter of intent, the largest issued at the time, general aviation revenue bonds, passenger facility charges, airline-supported rates and charges, Transportation Review Advisory Council funds, and several other sources. Although the City of Cleveland controlled all funding throughout the program, no city tax dollars were used on the new runway or its related projects.
In May of 2001, final designs for several projects were completed and construction began. The runway was constructed in two stages to meet urgent airline capacity requirements. Stage I, the 7,000-foot northern section, required purchasing businesses north of State Route 17 as well as relocating a major restaurant and the four-lane SR 17 and associated utilities to make room for the new runway’s additional safety area. This stage consisted of:
This project included moving a 677,000-cubic-yard soil stockpile and relocating all utilities to the western side of the airfield. For comparison, this 40-inch-thick runway section used enough materials in its construction to pave a two-lane road 4 inches deep from Cleveland to Columbus, 145 miles away. The new runway’s second stage proved even more complex because three huge projects had to be completed before construction could start. First, Abram Creek, a major feeder to the Rocky River, had cut an 80-foot-deep gorge across the entire airfield and through the runway’s path. PMT had to relocate the creek through four parallel 120-inch-diameter concrete reinforced pipes under the airfield, thus allowing the ravine to be filled and runway construction to proceed.
Three massive concrete structures were also required. The first, an inlet structure, routes the creek’s water uniformly into the four parallel pipes. The second, at the center point of the 3,800-foot run, is the first hydraulic drop structure, where the water drops 18 feet and enters the second section of the culvert system. The third structure is the outlet drop, where water leaves the culvert system, drops another 18 feet, and re-enters the original creek bed. The entire drop structure runs under 40 feet of structural fill material used to bring the airfield up to the finished subgrade for the new runway. Two onsite sources supplied the fill required to accomplish this massive task: an existing 1.5 million cubic yards of soil stockpiled from previous projects and excavation of a new 2.5-million cubic yard detention basin between the runways at the south end of the airfield.
The problem of Abram Creek solved, the Parsons-led JV turned to the second project. NASA Glen Research Center had several active and mothballed facilities directly in the new runway's proposed path. In addition, several facilities were in the blast zone of one of the critical relocated facilities and required relocation to another area of the NASA complex. One such facility was the Rocket Engine Test Facility (RETF), which was built in the 1950s and had been mothballed. The RETF had the added complication of being listed on the National Register of Historic Places. Parts from this facility were carefully salvaged for display in various museums, including the Smithsonian. In addition, a new video and model were created to preserve the facility for historic record. All these projects at the NASA center, totaling $107 million in design and construction, were necessary to obtain property transfer for airport runway use.
The third major operation required to complete the new runway involved reconfiguring and closing three solid waste landfills, again on the NASA property. These landfills were created during rocket testing in the 1950s. Parsons environmental experts conducted extensive sampling on NASA property in the summer of 2002. The landfill design is complete, and the permit process is under way. These same environmental experts are planning, obtaining and maintaining permit documentation, and supervising the landfill projects.
The new runway’s second stage is under construction. While electrical work continues through the winter, paving is suspended until this April. Both pavement and electrical work will be completed by July 15, 2004, so that the runway threshold can be relocated to its final position and the runway can be opened in its final 9,000-foot configuration on August 5. The new runway is classified category III (CAT III), which allows pilots to use it in very low visibility. The FAA is installing the navigational instrumentation, which is to be commissioned by November 25. At that point, the new runway will be fully commissioned as a CAT III runway. Additional instrumentation is also being installed that will allow simultaneous offset instrument approach (SOIA) landing and ground control, thus completing the full capacity increase needed by operations. SOIA instrumentation uses a state-of-the-art radar precision runway monitoring system, of which fewer than 12 are currently in use in the country. In addition, a surface movement guidance control system is being installed to enable surface traffic to navigate to and from the terminal in low visibility. Finally, a state-of-the-art computerized control and monitoring system will upgrade existing and new runway lighting control. All of this work is scheduled to be completed and in operation by February of 2005. One of the new runway’s primary design goals was to eliminate aircraft crossing incursions with the existing crosswind Runway 10-28. The 9,000-foot new runway completely eliminates any crossing of runway pavements, thus improving operational safety at the airport.
The parallel Runway 6R-24L still crosses the crosswind runway. One of the new projects in the approved future airport layout plan is a design to extend the existing parallel runway to the south, thus eliminating the only remaining pavement incursion. Parsons and the other PMT members are working hard to extend the contract to include the design and construction management of this new project, which should be completed by 2006.
