Structural Engineering

Structural engineering means more than just calculations—it’s about creating safe, efficient, and practical solutions that align with your project’s unique requirements. With deep technical expertise and a collaborative approach, Jon works directly with you to assess existing structures, design new systems, and ensure compliance with codes and safety standards. Whether you’re planning a renovation, addition, or new build, you’ll receive thoughtful, customized engineering that supports your vision—without overcomplication.

Architectural Drawings

Clear, accurate architectural drawings lay the foundation for any successful project. Jon produces detailed plans that align design intent with structural integrity—bridging the gap between concept and construction. These drawings ensure everyone, from contractors to inspectors, is on the same page, reducing delays and miscommunication. Whether you’re working with a designer or starting from scratch, Trailmark helps you move confidently from idea to execution.
