Overview
DACCO SCI, INC. is a Columbia, Maryland-based corrosion engineering and materials technology enterprise founded in 1988 by Dr. Chester M. Dacres. For over 37 years, it has bridged laboratory research and field implementation, delivering cathodic protection design, nondestructive testing, electrochemical analysis, and forensic failure investigation for critical infrastructure across water utilities, rail transit, and marine sectors. Its proprietary in-situ EIS corrosion sensors extend lab-grade electrochemical impedance spectroscopy to real-world field conditions.

Services
Corrosion Engineering
Assessment, evaluation, prevention, and management of corrosion in materials and structures to maintain safety, uninterrupted service, and economic efficiency.
Field Services
Nondestructive and non-disruptive physical field testing to evaluate infrastructure and identify materials without interrupting operations.
Laboratory Services
Electrochemical and analytical laboratory testing to evaluate corrosion behavior, predict material performance, and analyze degradation.
Materials Technology
Testing, evaluation, and selection of materials using metallurgical studies, coating evaluations, and environmentally induced degradation analyses.
Forensic Engineering and Failure Analysis
Laboratory and field investigation of structural failures and material degradation to find root causes and suggest repairs.
Nondestructive Testing
Non-disruptive inspection techniques to evaluate physical infrastructure and identify buried materials.
Asset Management and GIS
Development and management of custom databases and GIS systems to organize corrosion data and assist client maintenance schedules.

Projects
Internal Inspection Services
Water Supply
Located pipeline appurtenances, prepared lay schedules, measured wall and lining thickness, and performed weld inspections on water utility infrastructure.
View project sourceCathodic Protection Engineering Services
Water Supply
Designed cathodic protection systems to protect infrastructure from accelerated degradation in corrosive environments; also performed soil and water sampling to characterize environmental corrosivity.
View project sourceWater Main Forensic Engineering
Water Supply
Mapped wall thickness of a steel pipeline crossing beneath roadway bridges, tested compressive strength of adjacent concrete, and provided visual observations of related components.
View project sourceMetro Tunnel Stray Current Investigation
Rail
Investigated stray current activity inside metro tunnels, identified sources, and provided recommendations for minimizing stray current along with a monitoring program.
View project sourceThird Rail Metallurgical Failure Analysis
Rail
Performed metallurgical analysis of failed third-rail components; findings justified future material selections and changes to installation procedures.
View project sourceBulkhead Corrosion Condition Assessment
Marine
Condition assessments of existing steel sheet pile bulkhead structures at waterfront areas including test station evaluations, ultrasonic thickness testing, stray current testing, and structure-to-cell potentials.
View project sourcePier Rehabilitation Weld Inspection
Marine
Provided weld inspection via visual observation and magnetic particle testing for a pier rehabilitation project, plus quality control for steel member coating.
