world's busiest cargo airport was
awarded to ACPA member, Lane
Construction Corp. Kimley-Horn &
Associates was the design
consultant. Allen & Hoshall
handled construction
management.
The new runway, 18R-36L, was
built to handle heavy, wide body
aircraft including the Airbus A-380.
There is no other project with the
same magnitude and scope that
has been done in such a short
time, according to MSCAA.
The Memphis International Airport has three
north-south runways and one east-west
runway, all capable of handling heavy, widebody
aircraft.
The project had a broad scope and was very complicated. The entire runway, utilities,
and drainage were demolished. The project consisted of going down as deep as 30
feet in six different places to install the new storm water drainage system, water lines,
and sewer.
Proper subgrade preparation was necessary due to Memphis' predominantly clay and
silt soil. All the excavated material was mixed with three percent Code L lime to dry it,
and placed in stockpiles to be used as the project progressed.
A typical runway section contains six inches of soil cement, eight inches of cement
treated base, four inches of open graded asphalt, and 19 inches of concrete. The
pavement is thicker than normal because Memphis needs to handle heavier aircraft
than most airports because of Federal Express hub operations.
Before shutting down Runway 18R-36L for reconstruction, MSCAA spent the previous
year reconstructing an adjacent taxiway and turning it into a temporary runway. All
involved parties credit the extensive two-year planning process for the success and
speedy completion of the project.
MSCAA made sure that the consultants, owner, contractor, and inspectors were all
housed in the same complex at the airport. Everyone had immediate access to all
team members. The goal was that any problem or issue must be resolved (or on the
path to resolution) during the same eight-hour shift, which would save an immense
amount of time.
"We went back to basics. We did it the old fashioned way - check, check, and recheck.
We made decisions on site, and the contractor was always our teammate, never an
adversary. The teamwork and partnering played a tremendous role in the success of
the project," said Joe Polk, MSCAA manager of construction administration.
The runway reconstruction project at
Memphis International Airport project
was completed 30 days ahead of
schedule, giving The Lane Construction
Corp. a $2.5-million incentive.
The contractors MSCAA had initially
consulted said it would take seven
days a week, working around the
clock, to complete the project within
the nine-month time frame. Lane
Construction, however, worked one
12-hour shift per day after they
finished the demolition.
"We are very pleased with the
performance of the contractors,
designers, and suppliers. The project
exceeds our expectations in quality,
performance standards, and time to
construct," said MSCAA president Larry
Cox.
Concrete Pavement Provides
Environmentally Sound Deicing Facility
Project wins ACPA 2002 pavement award
In November of 2000, the Pennsylvania Department of Environmental Protection
ordered the construction of an environmentally sound deicing facility at the Pittsburgh
International Airport in Pittsburgh, PA.
The facility was expected to accommodate widebody aircraft in time for the 2001-2002
winter season.
The project involved installing more than 71,000 square yards of 16-inch-thick
concrete pavement with a high-density polyethylene liner under the entire area.
The American Concrete Pavement Association named the project a 2002
Excellence in Concrete Pavement Awards winner in the Commercial Service
& Military Airports category.
The project was awarded to Hi-Way Paving, Inc./Trumbull Corp. Joint Venture who
used a GOMACO SP-2600 paver and PS-2600 belt placer-spreader to pave alternating
lanes of pavement. A Rex Model S batch plant was located on a paved parking lot
within ½ mile of the construction site.
A 2,400-lineal-foot network of drains was installed in deep trenches to catch the
deicing fluid and move it through 4,600 feet of pipeline as large as 66 inches in
diameter on its way to a 1.4-million-gallon holding tank.
Given the time constraints and the added congestion that the construction caused the
airport (which had 423,000 aircraft landings the previous year), many phases of the
construction were conducted concurrently-adding to the high risk of the project.
Nonetheless, the project was turned over to the airport for the deicing season.
