Westech Process Solutions

Engineering and Construction Services


Combine our engineering, construction and maintenance experience to optimize the mechanical design and provide the lowest cost solutions. Our single-source approach facilitates communication, increases quality, reduces costs and improves schedule. Our in-house staff allows us to complete the concept and development, purchase equipment, prepare duct and pipe layout and start fabrication almost simultaneously, thus saving our clients time and money.  Our professional engineers are registered in Pennsylvania, New Jersey and New York.  We are accredited by USGBC LEED program.


When H.T. Lyons is involved in early stages of design, our budgeting assistance and constructability reviews maximize cost and schedule savings.  Our role as a team member with the owner and desginers allows construction to start on fast-track projects prior to the completion of the design documents.


Whether your facility is a chemical plant, power plant, pharmaceutical plant, semi-conductor facility, manufacturing facility or a food and beverage company, H.T. Lyons can assist your needs. We’ve worked in the industrial market since 1973 and our history of safety and success is well documented.  We specialize in industrial processes, high-purity piping and process ventilation. Our industrial maintenance contracts minimize system downtime.

Planning and BIM

Coordination, fabrication and sub-assembly drawings prepared by our in-house planning department enables our construction workforce to work effectively, minimizing changes, meet aggressive schedules, maximize quality, and control costs.

Our fifteen AutoCAD 2017 work stations with Fabrication CADmep, Navisworks and Revit improve coordination and vendor communication. Fabrication data is downloaded from our drafting stations to the automated shop equipment.

H.T. Lyons relies on the Trimble robotic total station for significant layout accuracy of all pertinent construction model data. We also utilize a state-of-the-art, Faro Focus 3D X330 Laser Scanner for our 3D data collection. This Class 1 laser provides us with distance, accuracy, and speed and is completely eye-safe.  After the data is collected, the scans are registered together and a point cloud is generated. The file then becomes available for you to use or we can create your 3D models

Large Utility Systems

H.T Lyons can design and build central utility systems and energy plants with thermal, renewable or co-generated power. Our experienced staff can design, procure, construct,  operate and maintain dozens of chiller plants, boiler plants, combined heat and power, landfill gas generation, fuel cells, micro-turbines, pumping stations, gas compressors, emergency generators and underground piping distribution systems. Our collaborative approach to design and construction has been proven to save between 10 % and 15% in costs and time.


Based on a business model similar to outsourced IT, HR, food service and other facility services, our COMPLEAT Solution allows our clients to focus on their core business. H.T. Lyons provides total mechanical services that include design, construction, operation and maintenance on a performance basis with financing or leasing options.
