As the Mechanical Contractor on design assist projects, Nash offers a full complement of pre-construction services during the design phase. Proper utilization of these contractor related activities assures the client that their facility will be constructed in the most economical and efficient manner. Major activities are cost estimates, scheduling, and constructibility reviews. These tasks all require a detailed analysis of component parts of the design and serve to identify potential long lead purchases which must be handled early in the construction phase.



We continue to employ engineers within our full service consulting, design, fabrication, installation, and inspection mechanical contracting services.


Modern buildings require modern standards of expertise in heating, ventilation, and air conditioning. Our management team are members of the American Society of Heating, Refrigerating and Air Conditioning Engineers.

Quality Control

Construction is a complex science, and our Project Teams believe that you deserve the highest quality project.


We understand the risks of poor performance and construction defects and as a result have developed a strict process of ensuring our delivery of a quality product. Through our integrated design and planning, we decide on functional performance and material specifications while allowing for the intelligent flexibility that original designs demand throughout the life-cycle management of our clients’ unique projects.

Every project team at William R. Nash is equipped with top of the line tools, best practice techniques, and above all, the training that is required to maximize our quality control and eliminate problems in the planning stages. Through a hands on approach we ensure that all projects adhere to every regulation and pass each inspection. Great Project Management is more than making sure the job gets done—it’s also making sure that the job is completed correctly the first time.


I have had the pleasure of working closely with W.R. Nash for the past 10 years. Their attention to detail and dedication to providing our clients a finished mechanical product is extraordinary. The hands-on commitment of their onsite management team is second to none...a top notch group of guys that are both knowledgeable and experienced in all aspects of the mechanical industry.
