Recent Projects
Featured examples that showcase Tweet/Garot’s experience and capabilities at customer locations throughout the United States.

Rexford-Longfellow Elementary School
Clintonville had undertaken an expansion project for their high school, allowing the revamped facility to be shared with middle schoolers. The former middle school underwent a complete renovation alongside of the high school, transforming it into the brand-new elementary school for the school district.
Before the transformation could be fully realized, the facility required essential upgrades, including comprehensive classroom renovations and the installation of an air conditioning system, as the building had previously been lacking this crucial feature. Tweet/Garot, who had already been involved in the high school renovation, was awarded the contract for the HVAC portion of the project in order to complete this task.
A range of major equipment, including six rooftop units, two air handlers, eight exhaust fans, and an exterior air-cooled chiller, among others, was installed to ensure optimal air conditioning throughout the facility.
This project was not without its challenges. Integrating the HVAC system with the existing mechanical systems posed a considerable obstacle. In addition, the project had a stringent timeline, and unforeseen equipment delays added to the pressure of meeting the customer’s schedule. Nonetheless, the dedicated team at Tweet/Garot demonstrated remarkable adaptability, successfully overcoming these hurdles, to meet the customer’s timeline and deliver an HVAC system that met the customer’s expectations.

Orthopedic Associates of Wausau & Wausau Surgery Center
The 61,000 square foot building was constructed for a joint venture between Orthopedic Associates of Wausau and Wausau Surgery Center. The building was set to consist of medical offices, clinical space, and an ambulatory surgery center. Tweet/Garot was contracted for the HVAC scope of the project due to a previous successful job with the general contractor.
This project saw two new foremen be successful on their first large job, great cooperation between Tweet/Garot and our subcontractors, and fantastic pre-fabrication from our Wisconsin Rapids Manufacturing Facility. Still, challenges were faced on the project that required the Tweet/Garot team to be flexible. A need for increased sheet metal manpower proved to be challenging in a market with labor shortages. Initial drawings required modifications to be made onsite in order to ensure all tradeswork was able to be installed in the given spaces.
Despite the challenges faced, this project was able to be completed in a timely matter and to the customer’s satisfaction. In addition, there were no injuries, a testament to good leadership and Tweet/Garot’s safety practices.

Team Winnebagoland Detail Center
Tweet/Garot was contracted to join the new construction project for Team Winnebagoland Detail Center in Oshkosh, Wisconsin. We were brought on to handle the HVAC scope of the project. Insulation and Balancing services were subcontracted and proved to be very helpful for this everchanging project.
Multiple challenges were encountered, but overcome successfully. Flexibility and adaptability enabled the project team to adjust plans according to changes in ownership decisions, equipment delays, labor schedules, and unfamiliar equipment, ensuring smooth progress. Our subcontractors proved to be very helpful when it came to dealing with these challenges.
Despite the many roadblocks, the project was completed within the ownership’s timeline, demonstrating the project team’s resilience and dedication. This project provided valuable insights into effective communication, adaptability, and training. Future projects will benefit from enhanced equipment operation clarity, comprehensive training, and improved coordination among stakeholders.

BCO Holdings
BCO Holdings/Horizon Square, a commercial real estate development, will house BayCare Clinic’s orthopedic, sports medicine, podiatry, and physical therapy services. Ernest Health’s Green Bay Rehabilitation Hospital will occupy multiple floors, providing specialized rehabilitation services to patients recovering from disabilities caused by injuries, illness, or medical conditions. Aurora and other future tenants were to occupy spaces on the fourth floor. In addition, the facility will have a Caribou Coffee cafe and a CrossFit gym. Tweet/Garot was hired to provide sheet metal and pipe fitting work to install multiple roof-mounted air handling units, among other things, in the building.
The facility required a complex HVAC system to accommodate the needs of the various specialized medical and wellness services to be located in the building. Tweet/Garot’s expertise in sheet metal and pipe fitting was essential to ensure the successful installation of the multiple roof-mounted air handling units with split DX cooling condensing units, a dual-fuel hot water boiler plant, electric humidifiers, several mini-split system AC units for electrical and data room cooling, packaged rooftop units for some of the tenant spaces, as well as a kitchen ventilation system. The team also ensured that the system met all regulatory requirements related to air quality and ventilation.

Siding Conversion Dust Collection, Upper Michigan
Tweet/Garot’s long history of dust collection work made us a top candidate for this project, which played a deciding factor in our participation. Our vast fabrication abilities and multiple fabrication shops allowed us to perform the work in the schedule allowed. We provided the sheet metal and piping labor primarily through the Michigan Upper Peninsula Unions with our leadership coming from Wisconsin. We are working side by side with operators, carpenters and mill rights.
Our expertise in dust collection and using correct practices in installation layout is critical. The ability of Tweet/Garot manufacturing facilities to weld heavy gauge ductwork, structural (hangers), and plate for stacks is also unique to the success of this project. The layout programs and fabrication process used in the Wrightstown, WI facility was critical in the coordination of timing the fabrication of the six separate dust collection systems on schedule. The whole nature of this project is to properly control excess dust throughout the process and contain it. The waste product is also reinjected and reused to maximize the use of the forest products. The filters are designed to maximize air quality.
The primary project challenges were meeting schedules and coordinating with the other contractors. Tweet/Garot provided on site project management for the duration of the project to coordinate with Miron management. Schedules were regularly changing to account for material delay issues and lead to day-to-day adjustments. In the end, both our project manager and superintendents were critical to achieve proper communication and coming up with solutions to unforeseen issues, to keep our team on schedule.

DTE – Matsches Dairy Farm
Tweet/Garot was awarded the Renewable Natural Gas project located on the property of Matsches Dairy Farm in Birnamwood, WI. With the completion of multiple other RNG projects around the Northeast portions of Wisconsin, this project fit well within the limits of Tweet/Garot’s capabilities.
This RNG project consisted of setting a large amount of equipment skids in which were placed around (2) new aboveground digesters. Both underground connection piping to the existing farm along with all of the associated aboveground piping to complete the necessary ties to each piece of equipment was performed by Tweet/Garot personally. A few unique piping systems installed included the following:
- Raw Manure
- Digestate
- Oxygen
- Biogas
- Tail Gas
- Nitrogen
Equipment setting was a large portion of the project which consisted of multiple critical crane picks based on the sheer size and weights of the items and their proposed locations on site. A list of equipment installed includes the following:
- Ferric Hydroxide Dosing System
- Boiler Skid (Prefabricated Building)
- Biogas Storage Membrane with Air Blowers
- Biogas Aftercoolers
- Vacuum Pump Enclosure
Approximately ½ mile or 2,000 linear feet of underground pipe was installed and about the same in above ground pipe for the project. In total, close to 1 mile of pipe, or 5000 linear feet, was installed over 11,170 manhours.
Challenging weather conditions along with shifting project schedules with equipment delivery dates being pushed out caused us to adapt our plan almost daily. Prefabrication of the large bore pipe and structural supports helped bring the project to a successful on time project completion allowing the owner to successfully start their renewable natural gas extraction from Matsches Farm.
