Airport Projects

Group Delta Consultants personnel have performed design-level geotechnical investigations and construction-phase services during major redevelopment and expansion of most local southern California airports including Los Angeles World Airport (LAX) in Los Angeles; John Wayne Airport in Orange County; Long Beach Airport; Burbank-Glendale-Pasadena Airport; Ontario International Airport; San Diego International. These projects included concrete taxiways, runways, terminal aprons, multi-storied parking structures, elevated and depressed roadways, arterial street and freeway improvements, pavement repair, and retaining walls.

Terminal Retrofit, Burbank Airport

Terminal retrofit at Burbank Airport (BUR)

Group Delta Consultants provided on-call materials testing and inspection services of concrete, masonry steel and fireproofing for the security retrofit completed for the terminal at the Burbank-Glendale-Pasadena Airport. We provided City of Los Angeles Certified Deputy Inspectors and ICBO Certified Inspectors. Our responsibilities also included the location of utilities for all excavating and new construction related to the retrofit. All laboratory testing was performed at our AASHTO, accredited laboratory.

American Eagle Ramp, LAX

Americal Eagle Ramp repair at LAX

A water line broke beneath a 12-inch thick concrete pavement at the American Eagle Ramp at LAX running for several hours flooding the ramp and developing voids under the pavement. Rather than remove and replace the pavement as recommended by another firm, Group Delta Consultants recommended treating the area with a fluid cement grout injected under pressure. Grout holes were spaced on about 12-foot centers (essentially at the center of pavement panels). In some areas, grouting was attempted in panels immediately adjacent to the treatment area or attempts were made to regrout selected panels inside the treatment area to confirm the success of the program.

Our innovative solution saved the client over a million dollars over the other firm's recommendation to remove and replace all pavement.

John Wayne Airport, Orange County

John Wayne Airport Orange County (SNA)

Group Delta Consultants personnel performed design-level geotechnical investigations and construction-phase services during a major redevelopment and expansion of John Wayne Airport in Orange County, California. This major project included concrete taxiways, runways, terminal aprons, two new multi-storied parking structures, elevated and depressed roadways, arterial street and freeway improvements, and retaining walls. Also included was the construction of various underground utilities such as storm drains, water, sewer, and electrical lines, fire hydrant laterals, manifold lines, jet fuel lines, and oil and water separator tanks.

Our construction-phase services included observation and testing during the overlay of existing pavements including runways, various taxiways, north and south blast pad, new wearing surface, and maintenance roads. These pavements were constructed as asphalt pavement concrete designed to FAA standards for Boeing 767 Aircraft. Specific tasks included testing and observation during grading, utility trench backfill, placement and compaction of select fill, and subgrade and base course preparation. Additional construction phase services included inspection during the driving of over 5,000 pre-cast, pre-stressed, square concrete piles for construction of the parking structures and elevated roadways. GDC also performed extensive in-house geotechnical laboratory testing on hundreds of samples collected during construction. These analyses included compaction, California Bearing Ratio (CBR), gradation, and sand equivalent testing in accordance with FAA, ASTM, and Caltrans requirements.


Ontario International Airport

Ontario International Airport (ONT)

Group Delta Consultants completed a geotechnical investigation for this roadway re-alignment project at Ontario International Airport. The existing Airport Drive was widened from Cucamonga Channel to Grove Avenue to accommodate three lanes of traffic in each direction. This included widening of approximately 40 to 60 feet south to parking facilities between Cucamonga Channel and Vineyard Avenue; widening approximately 50 feet north between Vineyard and Grove Avenue; replacing two 90 degree turns located at approximately 1,500 feet east of Grove Avenue with reverse curves including a bridge located at approximately 170 feet south of the existing bridge over the West Cucamonga Channel. The project also included reconstructing a channel wall for the new service ramp, retaining walls and a new storm drain.

Lindberg Field, San Diego

Paving at night at Lindberg Field San Diego (SAN)

At the Lindberg Field in San Diego, Group Delta Consultants performed a detailed evaluation of the existing airfield pavements and provided recommendations for areas of failed pavements. Included was repair or replacement of failed panels along Taxiway B. The pavement consisted of 15 in. of PCC overlying 7 in. of cement-treated base underlain by hydraulic fill soils. Two methods of repair or replacement included partial depth small repairs of the existing PCC pavement and construction of a new PCC pavement. Cement stabilization of the subgrade was performed at the Lindberg Field.
