City says you need an engineer
Your municipality requires a stamped plan set before they'll issue a permit, and you don't know where to start. Big firms often aren't built for small projects.
You need a licensed engineer who can navigate municipal review, cut through permitting red tape, and turn your project into a plan set built for approval.

Hammerstone Civil Engineering was founded on a simple idea: homeowners, small contractors, and local businesses deserve access to a real, licensed engineer — not a large corporate firm that treats smaller projects as an afterthought.
HCE combines specialized traffic engineering experience, municipal-review perspective, and field construction inspection experience to help identify issues before they become review comments.
Your plans won't just be prepared for a stamp — they'll be developed with the municipal review process in mind. That means a practical focus on clear drawings, code and ordinance requirements, and fewer avoidable revision cycles.
When you hire Hammerstone, you're dealing directly with the engineer who signs the plans.
Serving private clients across the greater Lehigh Valley, subject to professional conflict-of-interest limitations.
Professional ethics note: Hammerstone Civil Engineering does not accept private projects located within the municipality of the principal engineer's current public employment. If you're unsure whether your project falls within this boundary, contact us and we'll let you know.
Send the basics and we'll follow up with questions about scope, timeline, and what information is needed to evaluate your project.
