Tweet/Garot has over 155,000 square feet of manufacturing facilities including sophisticated and advanced technologies, precision tools, and a safe working environment that allows our skilled Union craft workers to focus on the details. We utilize lean manufacturing tools to standardize many of our fabrication processes, which minimizes wasted time and material, ensures efficient and just-in-time job site delivery, and creates significant savings for our customers.

Tweet/Garot takes the lead in prefabrication in all aspects relating to the installation of HVAC, plumbing process piping systems, and sheet metal equipment. Prior to the start of construction, our project team meets to break down the project by area, identifying vital parts of the systems eligible for prefabrication or modularization. The system’s position within the project construction schedule is then assessed to determine the optimum order of production.

Our project leadership team consists of project managers, field foreman, production manager, and the design team. We measure the quality and productivity of the prefabrication on each project. Each piece is compared to the initial forecast and productivity is measured through an earned value calculation. This assures the project budget remains on track.


Robust training and experience with
a variety of fabrication processes.


Tweet/Garot uses quality materials and processes
to produce high end customized finished products.


Our employees bring a depth of knowledge,
ownership and drive to provide the best customer experiences.


Optimizing efficiency through all phases
of design, fabrication and delivery.

Tweet/Garot is an innovator in manufactured and modular construction. With a focus on creating repeatable units and a highly standardized approach to design and construction regardless of the project type, costs are reduced. Modularizing our construction processes, where possible, allows us to eliminate variables in the construction process. The ability to control the production environment allows for significant improvements to labor productivity, quality, and safety, as well as typically decreasing a project’s duration. By doing so, we are able to keep costs low.

Tweet/Garot has also invested significant time and resources in understanding and producing multi-trade assemblies that allow the efficiencies already identified to occur across an entire project. We are experienced in collaborating with architects and structural engineers for solutions to integration challenges that present themselves early in the project lifecycle. Tweet/Garot has implemented several examples of multi-trade construction, such as zone-valve boxes (plumbing, framing, and drywall), overhead racking (mechanical, plumbing, electrical, and fire protection), and equipment skids (mechanical and electrical) on a number of projects and actively looks for the opportunity to do more during the design phase of a project.

We are committed to providing innovative industry solutions that improve the efficiency of construction through manufactured strategies. We believe there is much to be gained through better alignment of construction techniques and the installation of more complete elements. Modular Construction is a key to piece to increasing onsite productivity and reducing safety risks, which in turn creates a more cost-effective solution for our clients.

Tweet/Garot specializes in the design and manufacturing of process equipment, material handling, and specialty fabrications. We provide both turn-key process lines and stand-alone process equipment. Our ability to execute fast-track projects makes us unique in that we meet the demanding deadlines for our customers’ projects. A dedicated team of design, fabrication, and installation professionals brings more than 60 years of industry experience, serving the needs of our valued customers. Tweet/Garot assists you in the conceptual stages and takes you through the production of the finished product, as well as every step in between.
