Crouch Engineering provides a full slate of geotechnical and structural engineering services for track, bridge, structural and transportation projects.

Geotechnical Studies and Design

Geotechnical Design, Shoring Design and Plan Review, Foundations, and Retaining Wall Design

Crouch Engineering’s performs geotechnical evaluations, studies and designs for many types of civil and railway engineering projects, including slope stabilization; retaining wall design; bridge and building foundation design; and soil studies for grading projects.

Crouch routinely provides geotechnical investigations and geotechnical design for railroads, and governmental agencies. Recent geotechnical work includes geotechnical testing and foundation design for the Doc Newell Road Bridge over Norfolk Southern in Grove, KY; soil investigation for the CSX – NS connection track at Petersburg, VA; pile foundation design and shoring design for the construction of the Johnson Road bridge over NS in Petersburg, VA; a concrete retaining wall for Hamilton County, TN, protecting the NSR – Enterprise South Connection Track; and, the 3.1 mile long Goshen, IN siding extension project.

Our geotechnical engineers are responsible for coordinating construction management services, and conduct geotechnical investigations and perform geotechnical design; performing construction management and engineering, for Class 1 and short line railway track and bridge projects, and civil site projects throughout the country.

Crouch Engineering provides in-house geotechnical engineering services for track, bridge, structural and transportation projects, including shallow and deep foundation design, drilled pier design, micropile design, cantilevered and anchored retaining structures design, slope remediation and mitigation, ground improvement strategies, geotechnical finite element modeling (FEM) and limit equilibrium slope stability modeling.

Crouch Engineering routinely performs design calculations for earth pressures, settlement, slope stability, lateral support, retaining walls, shoring systems, grout underpinning systems, sheet pile retaining systems, drilled piers, driven and drilled pile systems, reaction block anchored walls, tieback anchor walls, and associated structural components.

Crouch Engineering’s Geotechnical services also include providing field engineering, construction engineering, and QA/QC engineering during construction of bridge, railway, civil, and geotechnical projects, and direction of periodic and full-time construction management personnel, depending on the individual project Scope of Work.

The Crouch Team has extensive experience in the design of gabion retaining wall design; steel reinforced concrete wall design; tunnel liners and rehabilitation; pile and lagging retaining walls; and, steel reinforced concrete crash walls for bridge pier protection.

Our Project Engineers are typically responsible for project management, specialty design, geotechnical studies and field engineering for government, industrial, private, commercial, highway, and railroad clients. They also manage start up projects, route planning projects, feasibility studies, and performs study and design for a variety of projects.

Crash Wall Design

Where additional tracks are added under highway overpasses, Crouch Engineering routinely designs crashwalls for existing structures or bridge piers incorporating crashwalls for new bridge structures over railroads.  Crouch Engineering follows AREMA guidelines and coordinates designs with state DOT’s.

 

Geotechnical Studies and Design Projects by Crouch Engineering

Toyota – Southeast - Railroad Siding/Capacity Expansion

The Project consisted of designing a new 3,500 track foot siding to serve Toyota-Southeast in Commerce, Georgia. Construction required an Aquatic Resources Alteration Permit (ARAP), gabion wall design and environmental permitting.

TDOT – SR 22

Crouch Engineering performed plan review, retaining wall design, shoring plan review and construction observation for a 177 foot long state highway bridge over the Railroad. Crouch Engineering worked closely with TDOT to develop a roadbed slope stabilization design to prevent slope erosion and settlement, and maintain railroad ditch flow. Plan review began in 2009, construction was completed in 2013.

Lhoist North America Railroad Tunnel Rehabilitation

Crouch Engineering worked with Lhoist North America (formerly Franklin Industrial Minerals) to assess the conditions of the railroad’s 900 foot long tunnel east of Westel, TN, and developed a methodology and plans for tunnel rehabilitation. The western portion of the tunnel was stable; however, the eastern portion had soil overburden, and the tunnel itself was constructed of timber sets. Groundwater infiltration and soil failures had been an ongoing maintenance problem for the railroad. Crouch evaluated several options for remediation and rehabilitation, including opening cutting, a metal arch replacement and the use of pre-cast replacement sections. The final method selected was a concrete liner, utilizing post-grouting. Crouch Engineering developed plans and specifications for the concrete liner project.

Norfolk Southern Railway Railroad Siding Extension

Crouch Engineering was given 30 days to design a siding extension at Tasker, DE. The project was constrained by limiting the construction for the new roadbed to the very narrow, existing railroad right-of-way. In order to provide the proper roadbed section, and remain within the ROW, Crouch designed a series of Gabion Basket retaining walls to stabilize the roadbed side slopes. Crouch performed all associated geotechnical work for this project, as well as the track and roadbed design.

Timber Trestle Replacements

Crouch Engineering performed all geotechnical investigations and foundation design work for the replacement of two BNSF timber pile trestles with a new ballast deck steel pile trestles in Lubbock, TX. Crouch set up and monitored drilling and testing, and developed bridge designs based on the geotechnical studies.

Retaining Wall Design

Crouch Engineering was responsible for geotechnical evaluation and design of a 400 foot long cantilevered, steel reinforced concrete retaining wall and culvert outlet in Jamestown, North Carolina. The project was necessary for the addition of a second main line track, and was constrained by limiting the construction for the new roadbed to the existing railroad right-of-way.

In order to provide the proper roadbed section, and remain within the ROW, Crouch designed a cantilevered concrete retaining wall to stabilize the roadbed side slopes. Crouch performed all associated geotechnical work as well as the surveying, foundation and wall design for this project.

Retaining Wall Design – Poe (Petersburg Autoramp Double Main Line Bypass)

Crouch Engineering was responsible for geotechnical evaluation and design of a steel pile / concrete lagging retaining wall at Poe (Petersburg, VA). The wall was used to retain enough railroad roadbed to construct two new main line tracks, while eliminating impacts to adjacent wetlands. Crouch performed all associated geotechnical work as well as the surveying, foundation and wall design for this project. Using this design, the project schedule was accelerated, and wetland impacts eliminated for this section.

Noah Reid Road Retaining Wall / Slope Stabilization Project

Crouch Engineering worked with Hamilton County and the Hamilton County Railroad Authority (HCRA) to provide planning, surveying, geotechnical study, investigation, evaluation and design and construction observation services for the design of a concrete retaining wall east of Noah Reid Road, along the Enterprise South Rail Line. The railroad cut slope had exhibited signs of unraveling and imminent failure. With homes located upslope of the railroad, a quick design and construction project was required.

Crouch designed a steel reinforced concrete retaining wall that mitigated the slope failure and potential damage to adjacent homes, while protecting the integrity of the railroad track and roadbed.
