An autonomous system for generating and interpreting point clouds of a rail corridor along a survey path while moving on a railroad corridor assessment platform. The system includes two rear-facing LiDAR sensors configured to scan along scan planes that intersect but not at all points and wherein neither scan plane intersects a main body of any rail car adjoined to a rear end of the railroad corridor assessment platform. The system also includes a plurality of high-resolution cameras for gathering image data from a rail corridor. The LiDAR sensors and the high-resolution cameras are housed in autonomously controlled and temperature controlled protective enclosures.

An autonomous railway track assessment apparatus includes: a railway track assessment platform including a boxcar including an enclosed space formed therein; one or more power sources located on the boxcar; a controller; a first sensor assembly in electronic communication with the controller oriented to capture data from the railway track; an air handling system located on the rail car, the air handling system including an air blower and a heater/chiller; a set of air ducts in fluid communication with the air handling system and the first sensor assembly for supplying heated or cooled blown air from the air from the handling system to the first sensor assembly. Data from the railway track is autonomously collected by the first sensor assembly controlled by the controller and such data is stored on the data storage device.
A wind turbine foundation and method for making a wind turbine foundation. The wind turbine foundation preferably includes a core member including a substantially cylindrically- shaped main body, a first outer flange extending out from the main body along an upper section of the core member, and a second outer flange extending out from the main body along a lower section of the core member, and a plurality of radial girders connected to the first outer flange and the second outer flange and radiating out from the core member.
A system and method for inspecting a railway track. The system preferably includes: a processor; at least one sensor oriented to capture data of the railway track; a data storage device in electronic communication with the processor; and computer executable instructions stored on a computer readable storage medium in communication with the processor operable to: determine an elevation of a surface of a rail head of a rail located on the railway track based on a distance to the rail head from the at least one sensor, determine an elevation of a surface of a crosstie of the railway track based on a distance to a top surface of the crosstie from the at least one sensor, estimate a total rail height and underlying rail support, and calculate a crosstie wear value based on the determined rail head surface elevation, crosstie surface elevation, and estimated total rail height and underlying rail support.

VERTICAL MANHOLE APPARATUS AND METHOD FOR PROVIDING ACCESS TO LEACHATE COLLECTION PIPES IN A LANDFILL
A vertical manhole apparatus for use in a waste facility to provide access to one or more leachate collection pipe access points. The vertical manhole is stabilized using stabilizing features extending out from a vertical pipe of the vertical manhole apparatus. The vertical pipe is formed by a plurality of pipe segments, and the stabilizing features include deadman anchors connected to first ends of cables. The apparatus further comprises a tension control system connected to the second ends of the cables, wherein the tension control system controls the tension of the cables by increasing or decreasing the tension between the tension control system and deadman anchors.

METHOD OF CHEMICAL TREATMENT OF SOILS CONTAINING NITROAROMATIC COMPOUNDS
A method for remediating hazardous materials susceptible to nucleophillic attack is disclosed wherein sodium hydroxide is applied to a treatment zone in situ for raising the pH of the treatment zone to at least about 12.5 so that alkaline hydrolysis effectively breaks down the hazardous substance by replacing a leaving group with a nucleophile. The method is well suited for in situ use in the vadose zone to treat contaminated soil and groundwater.
