Mobile LiDAR Survey of I-55 from Weber Rd. To Willow Springs Rd. – Phase III Survey Support
ASE provided verification of horizontal & vertical control, and an initial survey of existing conditions prior to construction of entire corridor using Mobile LiDAR. After construction was finished ASE performed a Mobile LiDAR Survey of the As-Built roadway through the entire corridor. Deliverables from Scan Van surveys was a fully registered non-classified point cloud delivered at first in .PTS files then .LAS files and spherical imagery files for use in TopoDOT.
IDOT ADA Surveys for Governors Highway & Sauk Trail in Richton Park
ASE performed topographic surveys and ADA compliant elevation surveys at intersection quadrants along Governers Highway and Sauk Trail in Richton Park. Using our 3D Mobile LiDAR scan van, ASE was able to scan the corridor to pick up topographic features including sewers, culverts, discharge pipes, catch basins, inlets, drainage structures, fire hydrants, manholes, handholes, traffic signals, wells, guardrails, retaining walls, large and/or overhead signs, railroad tracks, pavement, curbs, and other manmade improvements. ASE also located and detailed utility structures, and conducted an elevation survey.
Bridge Survey and Roadway Level Topographic Survey for Union Pacific Railroad CREATE – WA1
ASE provided bridge survey and roadway level topographic survey of crossroad structures. er. ASE also provided a track level bridge deck survey at 15 bridges. Mobile LiDAR and supplemental survey of Travel Level were conducted per UPRR Scope of Services for Traditional Ground Services. For the Mobile LiDAR, ASE stationed at 100 foot intervals and marked on outside rail. ASE measured existing surfaces and features within the project limits using 3D Mobile LiDAR Scanning. Low wire location and elevation of Com ED overhead lines within the UPRR ROW was also included. ASE supplemented the Mobile LiDAR with conventional survey in non-LiDAR areas.
Predesign Survey for Improvement of South Shore and Jackson Park Golf Courses
ASE performed a predesign survey, which used the Mobile LiDAR system deployed on an ATV to complement both static LiDAR and conventional survey methods. Initially, an Aerial LiDAR campaign was proposed in conjunction with the Mobile LiDAR effort, but because of the ability to mount the Mobile LiDAR system on an ATV, the aerial survey was not performed.
Various Topographic Surveys for Cook County
ASE performed Professional Topographic Services for Cook County’s Transportation and Highways Department. ASE also provided Subsurface Utility Engineering and Land Acquisition Services upon request. ASE provided topographic surveys along various roadway sections on a Task Order basis including stream surveys, ground topography, cross-sections, section line, quarter-section line, and centerline alignment, as required, drainage inverts, and right-of-way monumentation. Also ASE performed property surveys as required for parcel descriptions and valuations, utility locates, follow-up (pick-up) surveys as needed, and appropriate Quality Control measures for all submitted work. ASE also performed land surveys, highway surveys, premise plats, descriptions, monument records and all investigation and documentation required for property procurement and to prepare preliminary and final right-of-way plans.
O’Hare Airport – Mobile LiDAR Runway Survey
As a part of their Pavement Management Services, ASE used our proprietary Scan Van featuring our mobile scanner to survey client specified runways. Scan data was evaluated for condition rating including a crack analysis and inventory.
