Our Story
RES (Ruffini Engineering Services) was founded in 2005 with one clear goal: to provide engineering solutions that people can trust. What began as a small, family-run practice has steadily grown into a multi-state firm with offices in Colorado and Florida — yet we’ve held onto the values that shaped us from the start.
Over the years, we’ve supported hundreds of residential, commercial, and industrial projects. From helping homeowners safeguard their foundations to guiding businesses through permitting and designing seawalls or containment systems, our work reflects a wide range of expertise. No matter the scale, we approach each project with the same philosophy: listen first, communicate clearly, and deliver plans that stand the test of time.
What makes us different is our size — and our growth. We’re still a lean team, which means you’ll never feel like just a number. Every client has direct access to licensed engineers who care about the details and the outcome. At the same time, we’re expanding, adding services and locations to serve more communities across Colorado and Florida.
We believe engineering isn’t only about drawings and calculations; it’s about problem-solving, trust, and lasting relationships. That belief continues to guide us as we grow — one project, one partnership, and one community at a time.
Mission & Values
Our Mission
At RES (Ruffini Engineering Services), our mission is to make engineering practical, precise, and trustworthy. Since 2005, we’ve helped homeowners, contractors, and developers turn ideas into safe, buildable, and cost-effective designs. By bridging the gap between concept and construction, we deliver solutions that support our clients’ goals and strengthen the communities we serve.
Our Values
- Community – We are invested in the regions we serve, from Colorado’s Front Range to Florida’s Gulf Coast.
- Integrity – We do what we say, when we say it.
- Excellence – Every plan is reviewed and refined until it meets the highest standards.
- Collaboration – We listen first, communicate clearly, and work as a team with clients and partners.
Our Approach
We combine the personal attention of a small firm with the professionalism and experience of a growing company. That means every client works directly with licensed engineers who care about their project — no red tape, no confusion. As we expand, we remain committed to keeping our service responsive, transparent, and client-focused.
Our Vision
We believe engineering is about more than drawings and permits; it’s about problem-solving, trust, and long-term impact. Our vision is to continue growing while staying true to our roots — providing solutions that are not only safe and cost-effective but also strengthen the communities we call home.
Practical Engineering Solutions
At RES, we believe engineering is more than drawings and calculations — it’s about solving real-world challenges for our clients. Whether it’s a family worried about foundation issues, a developer balancing budgets, or an industrial client navigating regulations, our role is to turn complex problems into clear, buildable solutions.
Keeping Projects Cost-Effective
With material and construction costs climbing, every decision counts. Our team helps clients save money through practical design choices, efficient detailing, and value engineering. By focusing on buildability, we reduce unnecessary material use, prevent costly change orders, and shorten the path to approvals. That means you get solutions that are safe, code-compliant, and designed to make the best use of your investment.
A Partner You Can Trust
As a growing firm, we still offer the personal service of a small practice. You’ll work directly with licensed engineers who take the time to understand your goals and explain your options clearly. From residential additions to seawalls and industrial facilities, we approach each project with the same commitment: practical engineering solutions you can trust.

Locations & Licenses
RES proudly operates from our offices in Lakewood, Colorado and Fort Lauderdale, Florida. These two hubs allow us to serve a wide range of projects across the Rocky Mountain and Gulf Coast regions with local expertise and quick response times.
- Colorado – We design for the unique challenges of Front Range soils, freeze–thaw cycles, and mountain construction. Services include foundations, inspections, grading, drainage, and retaining walls.
- Florida – From coastal conditions to strict recertification requirements, Florida projects demand specialized knowledge. We provide seawall design, stormwater management, drainage solutions, and 30/40-year structural recertifications.
Beyond our two main offices, RES engineers maintain professional licensure in several additional states, enabling us to respond to client needs outside of Colorado and Florida. This broader reach ensures that we can step in to support projects across diverse conditions while maintaining the same commitment to safety, efficiency, and practical design.
