DAL Hydrant System for New Terminal Building
The 2006 Love Field Modernization Program, the largest construction project at DAL since the 1950s, prepared the airport to begin non-stop service throughout the United States.
The complex $519 million Love Field Modernization Program included terminal demolition and renovation; demolition of taxiways, taxi lanes and apron pavements to prepare for new pavement; improvements to utilities and drainage; and construction of a new hydrant fuel system.
Argus was retained for design and construction support services for the $11.6 million fuel hydrant system to support a new terminal building with 20 aircraft gate positions, all with the full complement of ground support systems including hydrant fueling.
To make way for the construction, three existing concourses were demolished along with nearly 70,000 feet of Jet-A and Avgas piping.
In a multi-phased implementation program, the new hydrant system included a looped piping system to maximize system flow rate capacity and mitigate system surge pressures. Isolation vaults are strategically located to facilitate a zoned Emergency Fuel Shut-Off (EFSO) system, periodic leak detection monitoring and testing and required maintenance while limiting the number of gates to be taken out of service. To supply this new hydrant system, more than 2,200 feet of new fuel transmission piping were installed using directional drilling techniques.
Approximately 1100 feet of dual 10" fuel transmission line was installed beneath two active runways and associated taxiways using directional drilling techniques. Almost 70,000 feet of former fuel lines were removed or abandoned as part of the phased construction program. Argus also prepared environmental planning documents that addressed procedures for contaminated soil and groundwater that were encountered during construction.
