OUR JOURNEY
Richard Catlin & Associates was Incorporated in North Carolina. The firm was the first environmental remediation professional consulting firm in the state.
1985
Founding of CATLIN
The firm was booming with innovation, with the team creating and constructing advanced remedial systems from the pulse air sparge to the air stripper and establishing CATLIN as a trusted resource for environmental solutions. In 1993, the firm was selected for its first NAVFAC consulting contract for UST assessment and remediation at MCB Camp Lejeune and MCAS Cherry Point.
1990s
Early Projects and
Expansion
As the years continued, CATLIN diversified its service portfolio to encompass geotechnical and civil engineering solutions to accompany its environmental capabilities. In 1997, upon receiving its first NCDOT contract for Subsurface Investigation of Roadway Projects, a rebranding ensued, culminating in the establishment of CATLIN Engineers and Scientists—a name that has since epitomized our commitment to multifaceted excellence.
1997
The Rebrand
In 2000, CATLIN established its own in-house geotechnical soil laboratory. Earning its AASHTO accreditation and analyzing thousands of samples throughout the years, the lab became a core asset to the firm.

Naval Industrial Reserve Ordnance Plant (NIROP) Fridley, MN Superfund Site
NAVFAC MIDLANT continues to work with EPA and Minnesota Pollution Control Agency (MPCA) at the Naval Industrial Reserve Ordnance Plant (NIROP) in Fridley, Minnesota, for the cleanup of chlorinated solvents, including trichloroethylene (TCE), tetrachloroethylene (PCE) and trichloroethane (TCA).
Client: Naval Facilities Engineering Systems Command Mid-Atlantic (NAVFAC MIDLANT)
Location: Fridley, Minnesota
Year Completed: 2024
A Groundwater Treatment Facility (GWTF) consisting of nine (9) extraction wells, an equalizer tank, air stripping units, and an effluent sump is utilized to treat the groundwater at the site. The effluent water is discharged to the Mississippi River. The GWTF was updated in 2021, and CATLIN helped with startup testing and evaluations.
In 2021, CATLIN was contracted to update the O&M Manual, provide O&M technical support to the on-site contractor, provide project management and support on all sampling activities, and prepare Annual Monitoring Reports (AMRs). CATLIN prepared a Sampling Analysis Plan (SAP) for monitoring requirements associated with a replacement groundwater treatment system and site-wide groundwater sampling at the site.
Provided within the SAP are guidelines for this project's systematic data collection and sample analysis. Following the Uniform Federal Policy for Quality Assurance Project Plan (UFP -QAPP) and the DoD Policy and Guidelines for Acquisitions Involving Environmental Sampling or Testing, the SAP includes worksheets that detail various aspects of the environmental investigation process and establishes protocols to allow for comparability and defensibility of sampling and analytical data.
CATLIN received the Federal Facility Excellence in Site Reuse Award for this project in 2022, in recognition of the firm’s role in the remediation and redevelopment of the NIROP site into Northern Stacks Industrial Park. As noted on the award, this redeveloped site is a community asset that houses multiple businesses, providing green space and generating job and tax revenue.

U.S. 17 Hampstead Bypass Project
Client: North Carolina Department of Transportation (NCDOT)
Location: New Hanover and Pender Counties, North Carolina
Year Completed: 2022
CATLIN, contracted by Stantec, completed an extensive subsurface investigation and provided geotechnical recommendations for the 14-mile U.S. 17 Hampstead Bypass project, a major $429M NCDOT roadway development. This project, comprising segments R-3300A and R-3300B, required CATLIN to
perform detailed soil testing, 186 SPT borings (3,632 feet), 349 CPT soundings (6,364 feet), and over 600 hand-auger borings along proposed roadway alignments.
CATLIN heavily utilized its amphibious drilling capabilities for this contract. The challenging conditions of “bottomless” and heavily wooded swamps, along with numerous river and creek crossings, required specialized drilling equipment. Borings were accurately surveyed using GPS with sub-meter and sub-centimeter precision. CATLIN also conducted geotechnical laboratory testing at its NCDOT-certified lab in Wilmington. Testing included grain size analysis, Atterberg limits, hydrometer tests, moisture content, and Wash 200 under modified AASHTO guidelines.
This was our first experience with CATLIN, and they essentially hit it out of the park on a project that was extremely challenging both in terms of design deadlines and the nature of the project location which included wood and dense ground cover, environmentally sensitive areas, high water tables, etc. There were also sections which required geotechnical work along US 17 highway. This company consistently has the can-do attitude and delivers on or ahead of schedule. They also easily met Stantec’s safety requirements for our certified subconsultant program. They are extremely responsive and willing to assist in all matters with all work being accomplished professionally. We plan to use them on future projects to the greatest extent possible.

Outdoor Infantry Immersion Trainer at MCB Camp Lejeune
CATLIN was contracted to provide comprehensive project and task order management, design, and construction plans for the Outdoor Infantry Immersion Trainer (IIT) aboard Marine Corps Base (MCB) Camp Lejeune.
Client: NAVFAC MIDLANT
Location: MCB Camp Lejeune, North Carolina
Year Completed: 2017
This project's goal was to create a training environment for small-unit rehearsal training, squad leader decision-making, and Pre-deployment Training Program Phase III.
The IIT features urban structures designed to replicate a geo-specific village, integrated with direction fire training systems, virtual simulation, and video instrumentation for after-action review. The project included the design and construction of 83 unique village structures, a modular After Action Review (AAR) building equipped with furniture, fixtures, and equipment, courtyard walls, site development, exterior lighting, gravel roads, a parking lot, a stormwater management system, site electrical and telecommunications infrastructure, and other miscellaneous appurtenances to meet the ITT’s design objectives.
CATLIN provided a full suite of civil engineering services, including design, permitting, subsurface geotechnical investigations and recommendations, and construction phase services such as submittal reviews, responses to requests for information (RFIs), record drawing preparation, and final state certifications. Design work was completed in December 2017, and the project was awarded for construction in July 2019 with a $26M budget. Following design completion, CATLIN continued to provide Post-Construction Administration Services (PCAS), including shop drawing review, RFI responses, and construction site visits.
The project’s sedimentation and erosion control plan covered 10 acres. Temporary construction entrances were designed for the access drives connecting the mock village to F-3 Range Road and the internal road to the adjacent mobile MOUT (Military Operations in Urban Terrain) site.

Project Site
The design included silt fences to protect off-site areas from disturbance during construction, temporary rock pipe inlet protection, and permanent outlet protection. Additionally, temporary check dams were installed in new swales to reduce flow velocity. Landscaping will feature seeding and mulching, with swales sodded for stabilization.
To streamline the design process, CATLIN utilized 3D models during design meetings with all project stakeholders. These models were a highly effective tool for visualizing the large and complex project, aiding in communication and decision-making across teams.
