What Makes RDH Unique?

Where We Specialize

Codes, building systems, and MEP design principles are complex and ever-evolving. Our decades of experience will help us to create an efficient and cost-effective solution for your project. But we don't stop at providing competent engineers. We go beyond to make sure that every client interaction is one that leads to repeat customers, by providing effective communication, education, and guidance to you throughout the process. Our LEED, Living Future, and WELL Accredited Professionals can create synergies within the design to help you achieve certification with these sustainable and healthy building standards.

Decision Making Made Easy

Over the years, we've had opportunities to work with architects, real estate developers, contractors, and government agencies. With each client, we work to set up a personalized portfolio of documents to meet their specific needs. RDH engineers have the tool set, software, and expertise to help you make an informed decision and meet your deadlines, be it in the form of building construction documents and specifications, to return on investment and energy analysis reports.

Founder: Ricky Dean Hiatt  PE, CEM, LEED AP

RDH is a boutique engineering firm first brought to life by Ricky Dean Hiatt. After graduating from the University of Nebraska Lincoln with a mechanical engineering degree, Ricky worked as a design engineer absorbing knowledge from the more experienced engineers. With suitable experience under his belt, an opportunity arose to work a project as an independent contractor. He knew how to engineer the system and how to show it on construction documents, but didn't have the supplies or technical drafting skills needed to complete the job. Regardless, he accepted the job and purchased a computer and hired a drafter and began his journey into business ownership. Years later, Ricky is the owner of a growing MEP engineering firm focused on creating an enjoyable work-life balance that cultivates reliable, sustainable, and economical engineering designs.

Plumbing and Fire Protection Engineering

RDH's mechanical engineering design experience includes Heating, Ventilation, and Air Conditioning (HVAC) in various climatic conditions. Our experience, knowledge base, and innovation help RDH from being a commodity service. We consider and analyze the most applicable systems for the project, from parabolic solar hot water heaters and thermal ice storage to the simple split system furnace we will make sure the HVAC system is the right fit for the project.

Our electrical engineering design background includes the design of power distribution for both medium and low voltage, site/campus power distribution, life safety systems, standby backup power for short and long durations, prime power generation with peak load reduction and cogeneration provisions, uninterruptible power supply systems, lighting control systems, and fire alarm systems.

Plumbing and fire protection experience includes sanitary waste and vent, process waste and chemical drainage systems, storm drainage and detention, domestic water, landscape irrigation, fuel gas and propane storage tank installations, gasoline/fuel oil storage and dispensing, and rough-in drawings for equipment installations, automatic sprinkler, deluge and pre action systems, clean agent suppression systems, and electric and diesel fire pumps.

Sustainable Design

Energy, impossible to see and always changing. Understanding how it's used in the built environment is critical for many applications such as energy purchase agreements, government incentives, and far more. We can thoroughly explain the energy behaviors of your building and the equipment associated for whatever your needs may be.

There are many factors that apply to the development of construction documents. Years of lessons learned has crafted the art of conveying information to the contractors. Our experience and a combination of thoughtfully drafted documents, responsive engineers, and several site visits will ensure your project will run smoothly from concept to occupied.

RDH is at its core a company that strives to promote the design of buildings that are healthy for the occupants and the environment. Our engineers integrate sustainable design principles in all areas of design. For projects seeking to showcase their commitment to going green through LEED, Living Future, or WELL Building Certifications, our accredited professionals and engineers can help make sure that journey is as smooth as possible.

We take pride in our work and the relationships we establish.

Large projects means large engineering firms, right? Wrong. RDH is comprised of a team of mechanical engineers that is the same as those found in large engineering firms. The difference that RDH has to offer is the flexibility of having top management on every single project and empowering the entire team to be in a leadership position. What we don't have is the top-heavy management whose salary increases the baseline engineering fee without the involvement in the project.
