SDT Consulting provides environmental documentation and compliance support to transportation and infrastructure project teams.

We work with engineering firms, environmental consultants, and project managers who are balancing complex schedules, regulatory requirements, and multi-agency coordination — often under federal funding constraints. When documentation workloads spike or compliance tasks begin to slow progress, we step in to keep projects moving.

Our role is practical and execution-focused. We support teams by:

• Drafting and QA/QC’ing environmental documentation

• Preparing permitting narratives and regulatory coordination materials

• Organizing submittals and tracking agency comments

• Strengthening documentation before it reaches review

We understand how quickly misalignment can disrupt a schedule. Clear, organized, agency-ready documentation reduces rework, shortens review cycles, and protects project momentum.

SDT Consulting supports projects across Virginia, Maryland, and Washington, DC, with experience navigating federally funded work and multi-jurisdictional coordination. We integrate into existing teams quickly, provide reliable support during peak workloads, and operate without adding unnecessary overhead.

No layers. No overcomplication.
Just steady, detail-driven support when it matters most.
