Recent Projects
Featured examples that showcase Tweet/Garot’s experience and capabilities at customer locations throughout the United States.
Chippewa Valley Technical College
Tweet Garot has had a longstanding partnership with Chippewa Valley Technical College, which made us a prime candidate to handle this remodel project. Our commitment to maintaining a good relationship with the customer has been crucial, and an open communication line throughout the project was necessary to deliver on their expectations to the fullest.
Tweet Garot operated as the lead contractor on this project and coordinated the schedule and meetings. We used our own resources for pipefitting, refrigeration work, sheet metal fabrication, and plumbing.
Tweet Garot’s scope for this project consisted of eliminating a steam heating system and adding boilers with hot water pumps and piping throughout the building. New AHU with VAV’s and a remote condensing unit were also installed to cool the building.
This job was completed with zero injuries, without any major rework, and was a testament to long-lasting success we have experienced with one of our many repeat customers.
WestRock
The West Point, Virginia mill project was a significant undertaking for Tweet Garot, involving a 23-day outage piping and sheet metal scopes. Brought on board two months prior to the outage, our team faced unique challenges due to the lack of finalized IFC drawings. This required adaptation and quick decision-making as tasks and designs changed frequently. Unlike typical outages where tasks are clearly defined, this project demanded high levels of flexibility and problem-solving. Our crew of 14 pipefitters and welders, along with 3 sheet metal workers, was composed of many familiar faces from previous projects across the U.S., fostering a strong sense of teamwork and collaboration.
Despite the summer heat and long 7-days-a-week, 10-hour workdays, the team successfully installed over 4,000 linear feet of piping systems, including compressed air, white water, warm water, mill water, steam, and condensate systems. Additionally, the sheet metal crew completed complex installations such as the trim system, dust collection, reel drum blower, electric control room HVAC, and exterior siding. At the peak of the project, our crew numbers reached 14 for piping and four for sheet metal, accumulating approximately 7,000 man-hours by the estimated completion.
The project’s primary goal was to enhance workplace safety and implement automation for transporting rolls to their pickup points. These upgrades will be completed by the end of September 2024, aligning with the commissioning of one of the oldest linear board machines still operational in the U.S.
The project was carried out with a commitment to safety, and to date, there have been no recordable safety incidents. The project’s success is a direct result of the team’s dedication, adaptability, and hard work under challenging conditions.
KPS Decommissioning Project Phase 1
Tweet/Garot was chosen as the design/build contractor for the ventilation system in the decommissioning of the Kewaunee Nuclear plant. The project required a 70,000 CFM ventilation system with HEPA filters and a dust collection system.
The space allocated for the equipment was a compact space, posing significant design and installation challenges. Our diverse team of craftsmen tackled these obstacles, fabricating and installing the 10 GA 124″x178″ duct required for the ventilation system.
This project followed a fast-paced schedule with a range of different challenges including poor weather. Our team worked diligently to install this large duct and equipment on time while also keeping safety a top priority for our team and the other trades working around us, resulting in zero injuries on site.
Green Bay East
Tweet/Garot was selected as the plumbing provider for the renovation of Green Bay East High School. The project consisted of three phases, addressing issues for multiple different parts of the building. On top of renovating the systems supporting the school, this project included an addition, making space for an expanded weight/training room.
Phase 1 of the project was focused on replacing the storm drainage system in the basement. The previous system was significantly dated and utilized clay piping, causing flooding issues. This area proved to be a challenge as the space was extremely tight which made moving and working on material difficult.
The second phase shifted focus to the boys and girls locker rooms. Individual shower units were installed for both locker rooms, along with general bathroom renovations. Shutoff valves for specific areas of the school were also installed during this phase. This addressed a serious issue with the old plumbing system. These valves had previously been located in the basement, which was very inconvenient when they needed to be utilized.
Phase 3 included the large addition for the new weight room and general renovations to the outdoor concession stand. Tweet/Garot’s scope consisted of the storm drain system, domestic water, and sanitary for the new addition.
Wisconsin Farmer’s Union Market On River
Tweet/Garot was recently contracted to convert an industrial facility built in the early 1900’s into a multi-use occupancy. The new utilization will house a public market, the Wisconsin Farmer’s Union Office, and residential apartments.
The market is located on the first floor of the building which includes multiple vendors along with restaurant spaces. Market tenants are required to utilize a minimum amount of locally sourced products and ingredients. The second level serves as the corporate headquarters for the facility owners as well as space available for lease. The third floor holds a residential occupancy, with apartments available for lease.
The first and second floors utilize packaged rooftop air handling units as well as a variable air volume (VAV), hydronic reheat system, served by two hot water boilers. The apartments on the third floor are served by fully electric air source heat pumps with electric resistance heating backup.
The age of the existing structure and techniques utilized at the time of its construction served as challenges throughout this renovation. The building is supported by mass timber construction with sub-10 foot beam heights. Minimal vertical clearance throughout levels one and two of the facility forced a complex duct system with multiple vertical shafts to distribute air throughout the facility. Additionally, the facility was built on the remnants of a previous building that had burned down prior to its reconstruction at this site. Several large pieces of the previous structure were still present below to the facility which had to be removed as part of the underground plumbing work. Despite these unique challenges, Tweet/Garot was able to deliver our scope on time and within budget.
Tweet/Garot’s involvement included the building mechanical, plumbing and building automation systems.
Plexus/Alpitronics
Plexus is a company that specializes in electronics manufacturing and product development with over 35 years of experience in design and manufacturing for high-complexity, high-reliability, and harsh environmental products. Alpitronics is an Italian company that specializes in fast-charging technology for electric vehicles. The company has been developing, producing, and distributing fast charging stations since 2017.
Tweet/Garot was contracted for a project consisting of redesigning the companies’ conveyor system and adding pre-manufactured testing pods and “sic stack” modules designed and built by the general contractor. The team handled the HVAC scope including both compressed air and gas piping. Ground mounted RTUs supplied by the owner were installed, along with the incorporation of controls into the Plexus system.
This project was run on a rushed schedule due to early delays, however all the teams involved in the project communicated well, allowing for an efficient and safe work environment. The scope of this project changed slightly due to deviations from the owner’s forecasts, so Tweet/Garot satisfied the current facilities needs and is on call for any further systems the facility may require in the future.
