About Us

When designing building system solutions, the engineers at EwingCole take pride in providing clients with the best in engineering leadership, problem solving, and cost effective results. EwingCole nurtures a collaborative relationship between architect and engineer so the building systems become an integral part of the building design. We offer our clients truly integrated architectural/engineering design solutions that result in high quality design and optimum building performance.

Our engineering services include all of the disciplines necessary for a well-coordinated and integrated building design; Mechanical/HVAC, Plumbing, Electrical, Structural, Fire Protection, Process, and Instrumentation & Controls.



At EwingCole, we believe that today’s HVAC building system design must take into account the critical need for energy efficiency, reliability, and flexibility while improving indoor air quality and occupant comfort. Our in-house energy modeling capabilities provide us the tools to effectively analyze first costs, as well as operating costs, to allow the owner to make informed decisions that will benefit their facility for the long term.

In addition to our in-depth experience in the design of HVAC systems for a wide variety of new facility types, we also specialize in Central Utility Plant Design, Utility Infrastructure Master Planning, Existing Facility Conditions Assessments, and Sustainable Design.



Plumbing Engineering at EwingCole includes the design of many different systems due to our project diversity. Engineering system design, code and engineering analysis required for these projects included the following:

Drainage systems for sanitary sewerage, special wastes and storm drainage, including neutralizing treatment for special wastes and pretreatment for storm reclamation.

Piping distribution systems for a variety of liquid and gaseous services including water systems for domestic, industrial, purified and animal water systems, medical and laboratory gas systems, fuel gas systems, and cryogenic liquid distribution systems.

LEED design water conservation and water reuse including storm, RO reject and ground water reclamation systems.

The design for all of these systems requires the selection of appropriate piping, pumps and storage tanks to be compatible with the service usage as well as economical, code compliant and energy efficient.



Our approach is to utilize our in-house expertise to advocate and design innovative, energy efficient power and lighting systems in collaboration with the design team and client.

We are committed to applying our collective technical knowledge/experience in all aspects of electrical system building design, including medium and low voltage power distribution, emergency power generation and distribution, renewable energy, power quality, energy management and controls, for all facility types and market segments within EwingCole’s portfolio.



Our structural engineers work closely with our architectural designers to bring structure to their vision.  We design building structures to balance competing interests of safety, economy, performance, human comfort, constructability, serviceability and visual elegance.  As a result of EwingCole’s diverse portfolio, we have broad experience with various structural systems and their application to new construction and renovation projects.


Fire Protection/Code Consulting

EwingCole maintains a group of licensed Fire Protection Engineers dedicated to engineering life safety systems, offering code consulting services to both in-house designers and our clients, with an eye toward full integration of the built environment. As a national practice with many high-profile projects around the country and in a wide variety of industries, our Fire Protection Engineers have a successful history of negotiating solutions with owners, code officials, insurers and other stakeholders.

Our staff is particularly adept at resolving challenges employing the full breadth of available tools from hand calculations through computational fluid dynamics fire models and 4Dimensional egress models.


Process Engineering

Process Engineering is the heart of design for manufacturing projects. Our Process and Automation Engineers are capable of addressing the broadest range of industrial process, from chemical to pharmaceutical plans. Our SME’s have extensive experience in Biologics, Single-Use, Oral Solid Dosage, Semi-Solids, Aseptic and Medical Devices manufacturing.

We start each project by gaining a thorough understanding of the customer’s needs by developing user requirements upon which to base a sound design, from concept to detailed engineering, to construction administration support and procurement activities.

The design of critical utilities, material handling and related support systems go hand-in-hand with the design of the manufacturing process. Our strengths lay in our integrated AE approach to design, from 3-dimensional piping design to automation and controls. Facility and infrastructure design is developed upon the process design to establish the facility flows, manufacturing areas, warehouse, laboratory and support spaces requirements.

Safety is of paramount concern and built-in to the design of the process and facility as part of our design approach. Our experts have conducted many formal Process Hazards Analyses (PHA), participating both as SME’s and Facilitators. The results and recommendations from these analyses are used to further develop and refine our Internal Quality Protocols.
