Our Philosophy

Collier Engineering fosters teamwork to create solutions engineered to last.  This means utilizing our diverse and talented pool of professionals to develop solutions that are focused on client goals. We encourage communication and work to maximize outcomes while maintaining budgets and schedules.   

We pride ourselves on successful project delivery, and our team works proactively to minimize challenges and mitigate risk during construction.  This is accomplished by our ability to cross-train design staff with construction inspectors so that our engineers have a real-world understanding on how a design is implemented on-site.  The result is a collaborative studio where we develop designs and plans that can be built efficiently and cost-effectively, ensuring our projects stay on schedule and under budget.

This philosophy extends into the field during construction. Our inspectors are trained to help identify and navigate challenges before they become an issue.  We work closely with the Contractor to help determine resolutions to typical challenges while protecting the owners’ interests.

Throughout our work, we maintain focus on how we best serve our clients. We work hard to cultivate relationships based on professionalism and trust.   We take great pride in developing the infrastructure that supports healthy, vibrant communities.
