In traffic, trying to make that flight at LAX? Wishing there was a better way?
The Leighton Solution.
Leighton provided geotechnical and hazardous materials evaluation for the alternatives analysis and for a future environmental document.
We prepared a preliminary geotechnical report evaluating the geologic-seismic hazards impacting the project and provided recommendations for tunneling, aerial structures, underground and aerial stations, and earthwork. Leighton also prepared a tunnel feasibility report for an alternative that traverses under the airport runways.
Our work on this project included two main components: a geotechnical assessment evaluating geotechnical/subsurface/seismic impacts and a Phase I Preliminary Environmental Site Assessment (Phase I PESA) evaluating hazardous materials impacts.
The completed Phase I ESA report identified 14 high priority sites with petroleum/fuels/oils and VOC impacts to soil and groundwater.
