Randall Airport – Runway Safety Area Improvements / Earth Retaining Wall

DESIGN »

Location: Orange County, New York
Client: Randall Airport
Completion Date: 2011

TSPE designed a standard Runway Safety Area (RSA) at Randall Airport. The safety area was nonconforming due to the transverse grade and the restrictions imposed by the property line and Interstate 84. A standard RSA was required to meet FAA standards, provide a surface from which the airport equipment would be able to maintain (i.e., mow), and allow for inspection of the airport perimeter road.

TSPE designed an earth-filled retaining wall (1:1) and minor drainage improvements. An area was excavated (4,300 CY) and a geogrid was specified to wrap layers of soil to stabilize the slope. Proper compaction and wrapping techniques were essential to the slope’s stability. The project included local permitting and construction documents used for public bidding.

TSPE also provided construction inspection for a runway safety area project which constructed an earth-filled retaining wall (1:1) to provide drainage improvements. A geogrid was used to wrap layers of soil to stabilize the slope. Proper compaction and wrapping techniques were essential to the slope’s stability. The project resulted in 4,300 CY of excavation and improved the safety of the airfield.

Morristown Municipal Airport – Taxiway A and B Reconstruction

DESIGN »

Location: Morristown, New Jersey
Client: Morristown Municipal Airport
Completion Date: 2007

 TSPE designed a full-depth reconstruction of Taxiway A (north of Runway 13-31) and Taxiway B (west of Taxiway A). The total pavement areas included Taxiway A (4,320 ft x 60 ft), Taxiway B (2,935 ft x 60 ft), Taxiway K (170 ft x 25 ft), Taxiway C (170 ft x 60 ft) and Taxiways F, G and H (each 330 ft x 60 ft).

The design parameters included reducing the taxiway widths from 60 to 50 feet and incorporating Group III aircraft geometric requirements. The reduction of the pavement widths required the relocation of the existing edge lighting systems and the airfield signs. All electrical replacements were base-mounted lights with cables in conduit. TSPE also completed the design of all drainage improvements within the project area, prepared a Soil Conservation District Permit Application, and coordinated the NJDEP Multi-Use Individual Permit Application and associated Wetland Permits through the use of subconsultants.

TSPE provided construction inspection services for the full-depth repair of Taxiway A (north of Runway 13-31) and Taxiway B (west of Taxiway A). The total pavement areas included Taxiway A (4,320 ft x 60 ft), Taxiway B (2,935 ft x 60 ft), Taxiway K (170 ft x 25 ft), Taxiway C (170 ft x 60 ft) and Taxiways F, G and H (each 330 ft x 60 ft). The project included drainage improvements, an edge lighting system, airfield signs, working in and around wetlands, removal of contaminated soils and extensive phasing to keep the airfield operational.

Dutchess County Airport: EMAS Pad and Bed Design

DESIGN »

Location: Dutchess County, New York
Client: Dutchess County Airport
Completion Date: 2004

The EMAS pad was designed by TSPE with the EMAS bed (250 feet long and 120 feet wide) designed by ESCO. The EMAS provided the needed runway safety area improvements on the roll-out end of Runway 6. A highway crossing the standard RSA and the need to maintain the available runway length, of 5,000 feet, left an Engineered Materials Arresting System as the best possible improvement for this precision instrument runway used by nearly all of the jet aircraft operating at the airport. TSPE oversaw the EMAS installation site preparation including relocating a natural gas line, modifying the drainage, and constructing the asphalt pad. ESCO provided on-sight supervision of the EMAS block layout and placement.

The joint efforts of TSPE, ESCO and an experienced contractor made the project a success. The installation used tried and proven methods and meticulous design specifications to make a difficult project proceed smoothly, on time, and under budget.
