Surveys You Can Trust

Crouch Engineering uses the latest tools for the collection of GPS based data needed for various maps, charts and plans.

GPS Surveys (GIS Ground Surveys) for PTC Systems and GPS Topographic Surveys and GIS

Crouch Engineering uses GPS receivers, GPS survey equipment, aerial surveys, LIDAR surveys, and other tools for the collection of GPS based data needed for the preparation of maps for planning and engineering purposes including right-of-way maps, location maps for plans, the preparation of track charts, geographical and graphical presentations of data, conceptual plans, GIS maps, etc.   Crouch Engineering utilizes ground surveys and aerial surveys to produce many of its maps, and has access to USGS maps and other existing digital format maps and ArcView Compatible databases.  

Large linear route projects are surveyed using helicopter or other aircraft mounted laser equipment (LIDAR), and the data are reduced to prepare digital terrain models used for railroad track design.

Crouch Engineering, P.C. uses state of the art Global Positioning Satellite (GPS) and Laser Electronic Distance Measuring (EDM) receivers and robotic total station equipment to conduct topographic surveys on the ground that are used for highway/railroad grade crossing projects, grade separations, industrial development projects, track design and construction, hydraulic studies, preparation of railroad style valuation maps, right-of-way encroachment surveys, line changes, resolution of right-of-way issues, property exchanges, construction staking, permanent easements, preparation of maps and plans. Aerial surveys are conducted where the magnitude of the project makes it more cost effective than conventional surveys.

Crouch Engineering, P.C. uses state of the art Global Positioning Satellite (GPS) receivers such as the Topcon GRS-1 to conduct PTC Ground Surveys, and verification surveys for compliance with FRA PTC rules. Crouch dispatches one- or two-man teams as needed to collect GPD data for railroad assets that are documented as part of the PTC data, including, but not limited to switch points, theoretical points of frogs, grade crossings, signal bungalows, signal masts and signals, derails, etc.

Case Study – Crouch Engineering performed GPS location surveys for 25 RailAmerica Railroad properties in order to verify the actual number of track miles of track on each individual short line railroad. Crouch conducted these GIS ground surveys from coast to coast, collecting GPS data for each line. Crouch also developed line maps for each of the railroads. The resulting mileage totals were used to update tax return filings related to the short line tax credits for maintenance work, which were based on miles of track owned and maintained, generating millions of dollars in tax credits over several years.

Norfolk Southern Railway / Amtrak Passenger Project

The Crouch Engineering design team worked closely with Norfolk Southern, the Virginia DRPT, Amtrak, CSX, local agencies, utilities, and regulators to plan, survey, design, permit, bid, manage, and stake out the following projects, which were a part of the overall Norfolk to Petersburg, VA Amtrak project:

- New Amtrak Station Platform and Platform Track; Harbor Park, Norfolk, VA Survey, design, utilities, permitting, bid phase, and staking - 2,000 TF platform track, main line realignment, I-95 Crash Walls, a new 800’ passenger station platform, and platform track.

St. Julian Amtrak Servicing Facility and New Wye Tracks - Norfolk, VA – Planning, survey, design, utilities, permitting, bid phase, and staking wye tracks (8,600 TF), main line realignment, & new Amtrak passenger train servicing facilities and wye to be used for Amtrak passenger trains to turn around

- NSR - CSXT Connection Track – Survey, design, permitting, utilities, bid phase, and staking for a 7,000 TF connection track and CSXT double track.

- New Double Mainline and Auto Ramp Bypass, Petersburg, VA – survey, design, permitting, bid phase, and staking for a new 6,200 TF mainline bypass

- Siding Extension & Highway Realignment, Petersburg, VA – survey, design of track, bridge overpass, and highway realignment, utilities, permitting, bid phase, project management., and construction staking for the 0.5 mi Johnson Rd. Realignment and railroad bridge overpass widening.

- Redesign of Portlock Yard, Chesapeake, VA – planning, survey, design, utilities, permitting, bid phase, and staking for additional storage tracks, a new switching lead, and redesign of other yard tracks to allow passenger trains to move through the yard without interference from yard switching operations.

Redesign of the Norfolk Southern Railroad South Yard

Crouch Engineering performed survey, track, grading, and drainage design, permitting, erosion control plans, coordination with the City of Mobile and ADEM, bid phase, and construction staking for the redesign of South Yard, to increase railcar storage capacity. The existing ADM unloading facility and rail access had to be preserved. Existing yard drainage was poor - drainage improvements were designed for the entire yard. The project also involved relocation of an existing C&S microwave communications tower.

Volkswagen – Bonny Oaks Dr. Underpasses, Yard Expansion, Hickory Valley Road Overpass Replacement and NSR Connection

Crouch Engineering worked with Hamilton County, Enterprise South, the HCRA and Norfolk Southern Railway (NSR) to provide planning, surveying, permitting, design and related services for the redesign and expansion of an existing railroad yard to serve Volkswagen in Chattanooga, TN. As a part of the Volkswagen Project, working with NSR and Hamilton County, Crouch Engineering designed a new connection with NSR, and facilitated a connection with CSXT. In addition, Crouch Engineering designed the replacement of the Bonny Oaks Drive single track overpass with three new through plate girder bridges, accommodating the tracks necessary for the expanded yard and widening of Bonny Oaks Drive as well. Crouch Engineering also designed the replacement of the Hickory Valley Drive Overpass over the Enterprise South Railroad to accommodate heavier highway traffic as well as provide additional track clearance for the railroad.

NERA – SR-24 (US 70), and SR 109 Grade Separation Projects

Crouch Engineering worked with the Nashville and Eastern Railroad Authority and TDOT to plan, survey and design a 3.2 mile long railroad main line realignment. This project eliminated two major railroad/highway grade crossings, providing grade separations at SR 109 and SR 24 (US 70) and improving railroad track geometry for higher speed operation in the area. Crouch performed all

- planning

- topographic surveying and mapping

- environmental permitting

- track and roadbed design

- one minor grade crossing redesign

- bridge design for two new ballast deck concrete/steel bridges at stream crossings (two bridge demolitions)
