Services
Structural Engineering
Our structural engineering team specializes in designing and evaluating complex systems for commercial, industrial, and infrastructure projects. We provide full lifecycle support from initial assessments to construction phase services, including foundation design, seismic upgrades, and structural steel evaluations. Utilizing advanced BIM technology, we ensure seamless integration of new and existing structures while meeting modern safety and performance standards.
Geotechnical Investigations
We conduct comprehensive subsurface exploration and testing to assess soil properties and geological conditions. Our expertise includes karst remediation, sinkhole stabilization, and foundation design for challenging terrains. By combining field testing with laboratory analysis, we develop tailored ground improvement solutions that ensure long-term structural stability and regulatory compliance for large-scale developments.
Construction Materials Testing
Our certified technicians perform field and laboratory testing of construction materials including concrete, asphalt, and steel. We verify compliance with project specifications through soil compaction testing, rebar inspections, and structural element evaluations. This critical quality assurance process helps maintain safety standards and prevent costly construction delays through real-time data monitoring.
BIM Solutions
We leverage Building Information Modeling (BIM) to enhance design accuracy and interdisciplinary coordination. Our REVIT-based workflow supports 3D visualization, clash detection, and construction sequencing for complex projects. This technology enables clients to optimize design decisions, reduce change orders, and improve facility lifecycle management through data-rich digital representations.
Federal Program Management
We specialize in delivering engineering solutions for federal infrastructure initiatives. Our team meets stringent regulatory requirements through comprehensive planning, documentation, and execution strategies. With proven experience in USACE projects and public works contracts, we ensure compliance with federal standards while maintaining project efficiency and budgetary control for government clients.
