Neal Robertson, P.E.

Practicing engineering since 1993, I am a licensed professional engineer in 37 states.  After 16 years working for corporate engineering firms, I started this company in order to focus on quality of work over quantity.  My goal is to offer structural engineering services with a personal touch.  Whether structural inspections, design of stairs and railings, or acting as engineer of record for an entire project, you can expect timely service focusing on customer value and comprehensive engineering solutions.

Structural Inspections

When you need to know if the work was done correctly or if you have a problem, we offer structural evaluations for both commercial and residential projects.

Special Inspections and Construction Observations

The international building code requires objective, competent, and independent inspections for a long list of critical construction elements. We can assist with determining which inspections are required for your particular project and provide you with impartial, timely and competent inspection services.
