Green Bay Packers Visting Locker Room – Rooftop Addition
Tweet Garot was once again selected to be the HVAC and controls contractor for an addition to the rooftop unit servicing the guest locker room at Lambeau Field. The Packers value the craftsmanship and consistency in the work we have performed with them for the past 20+ years, leading to our continued collaboration on this project.
Tweet Garot was tasked with moving equipment off the existing roof of the facility and relocating it to the newly constructed portion of the roof. The equipment consisted of four large exhaust fans, one roof hood, one in-take hood, and three condensing units. This made up a majority of the team’s scope, as all interior work involved common finishes and made for a smooth, fast-paced completion of the project
ACC was utilized throughout this project’s delivery, and proved to be an effective method keep all the project’s information in one place throughout the duration of the project. This allowed the team to not only meet this project’s fast-paced schedule while also avoiding any workplace injuries.
Menasha Public Library
The Menasha Public Library is undergoing a significant renovation. This 30,000-square-foot space now includes a variety of public-use areas, such as a kitchen designed for educational purposes, a state-of-the-art makerspace featuring a laser engraver and residential water jet, a new children’s section, and three dedicated focus rooms.
Tweet Garot was responsible for the plumbing and HVAC upgrades. The plumbing improvements included the installation of 14 new sinks and urinals, as well as the relocation of water fountains. HVAC upgrades involved the addition of two new boilers, hot water and chilled water pumps, a new chiller to replace the old cooling tower, and a new air handling unit (AHU) with nine additional Variable Air Volume (VAV) boxes to accommodate the expanded spaces.
This project ran on a fast-paced schedule and existing document did not properly reflect the building’s current systems, making for a significant hurdle for the team to overcome. Luckily, substantial pre-fabrication along with proactive communication amongst the team onsite allowed for a timely completion of the project with no injuries.
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.
