Services

Water Engineering

Supplying, treating, and distributing potable water involves navigating regulatory standards, conducting capital improvement planning, and optimizing water chemistry. Experienced engineers, operators, and chemists collaborate to support municipal clients in securing funding and delivering safe drinking water.

Wastewater Engineering

Protecting local aquatic resources requires a deep understanding of environmental regulations and wastewater process design. Specialized teams design collection, conveyance, and treatment systems that balance ecological responsibility with long-term operational feasibility.

Water Resources

Managing stormwater runoff and protecting local watersheds requires close coordination with county water resource districts, municipalities, and state agencies. Dedicated hydrology and hydraulics experts design resilient drainage and flood control infrastructure.

Transportation Engineering

Designing urban and rural roadways demands compliance with complex federal, state, and local standards. The practice plans and executes highway improvements, multi-use recreational trail networks, and advanced traffic control systems.

Municipal Engineering

Providing public entities with efficient infrastructure solutions involves careful listening and balancing current needs with long-term maintenance and operational costs. Collaborative teams deliver end-to-end support for local streets, utilities, and GIS mapping.

Electrical Engineering

Delivering safe, reliable power distribution systems requires close coordination with utilities, facility owners, and contractors. Specialized engineers design low- and medium-voltage power networks, control systems, and safety infrastructures for diverse commercial and public facilities.

Environmental Engineering

Navigating complex local, state, and federal permitting processes is essential for the timely delivery of infrastructure projects. Field specialists perform aquatic resource delineations, biological assessments, and compliance monitoring.

Land Surveying

Providing precise spatial data is critical for property, design, and construction planning. Experienced survey crews utilize modern technologies to deliver subdivision platting, easement mapping, and construction staking.

Funding Assistance

Securing funding packages makes major public capital improvements economically viable. Dedicated funding specialists identify, apply for, and administer diverse state and federal grant and loan programs.
