Featured examples that showcase Tweet/Garot’s experience and capabilities at customer locations throughout the United States.
Tweet/Garot was chosen for the plumbing scope of this project as a result of a successful and longstanding relationship with Hoffman Construction. Clintonville is a small community, so this was a high-profile project for the area.
Special craftsmanship was required from Local Union 400 plumbers. The union workers were faced with building construction of interior masonry walls, which required a precise rough-in for final fixtures to align and look pleasing.
SUR Insulation and Ostrenga where subcontracted on this project to lead the plumbing excavation and insulation. All scrap material was recycled so it could be repurposed for future projects.
This project wasn’t without challenges; a tight schedule and working within an occupied school meant scheduling worksite days and times to prevent disruptions for students and staff.
Tweet/Garot was successful in providing a great end product for the students and staff in the community. Click the links below to see the 3D models of this project:
Tissue Converting Line, Oregon
This project included a demolition of an existing converting line and replaced with a new, modern technology converting line. Many mechanical systems were installed to modify for the retrofit:
- Building Ventilation
- Dust Collection
- Trim Collection
- Cabinet Cooling
- Potable Water
- Mill Water
- Compressed Air
- Process Drains
Tweet/Garot was chosen to be on the construction team based on our expertise with paper converting mechanical projects. Like many of our paper mill projects, this particular location was in a remote area. Tweet/Garot has proven to travel well, successfully complete mill projects with minimal down time and remain competitive throughout the country.
Green Bay Correctional Institution
Tweet/Garot was chosen as the mechanical contractor to remodel 592 jail cells in the Green Bay Correctional Institution as we had the resources to cover the scope of project specifications. Our work included mechanical and plumbing upgrades to the facility.
GBCI was first opened in 1898 and most of the buildings were built by prisoners. 16” walls were constructed on each side of the mechanical chase. We cored approximately 5,300 holes throughout these larger thick walls to provide all new waste and water piping to the new combination units. Accurate measurements and layout where crucial for laying holes for coring.
592 cells were remodeled with new stainless steel combination units which included both a combined toilet and sink. The new units are equipped with wireless communications and water control devices. Each unit can be remotely monitored, and have its water shut down from the main computer in the security room. All new riser piping was prefabbed and installed onsite to meet the 16-cell turnover every three weeks.
Some challenges of this project came with the prisoners in close proximity to the work sites. All workers on site always needed an escort and tools had to be kept far away from the work area to guarantee prisoners couldn’t get their hands on them. Regular material checks were required to keep track of all materials. Nevertheless, some of our biggest challenges that Tweet/Garot has experienced during a job to date didn’t stop this project from being completed on time.
Hospital Sisters Health System (HSHS) Prevea Ambulatory Surgery Center
Tweet/Garot Mechanical was chosen to be the plumbing contractor for this newly built 35,000 square foot surgery center. The customer chose Tweet/Garot for our ability to execute the scope of work required for the project specifications.
This was a large medical gas job which included medical vacuum, medical air, oxygen, nitrous oxide, and instrument air. NFPA 99 medical gas certified installers were required for installation and code certifications.
All in-wall plumbing rough-ins included in this project were prefabricated for quick and predetermined installation requirements which, allowed for maintaining the scheduled completion date. This project was constructed amid the COVID-19 pandemic and all employees onsite where required to wear masks and comply with HSHS vaccination requirements.
All construction waste was separated between recyclable waste and non-recycled waste material.
Challenges of this project included supply chain disruptions on several materials including medical gas and LV wiring, undelivered parts, and additional time and resources required to add drawing details. Despite these challenges, there were no reworks and the job was closed out well.
Aurora Sheboygan Memorial Medical Center
This project was a replacement hospital located in Kohler WI, approximately 417,000 sq. ft. and comprised of a CUP, D&T, Bed Tower, and MOB. The HVAC Scope of Work included Pipe Fitters, Sheet Metal, Energy Controls, HVAC Insulation, TAB and Fuel Oil Tank and underground piping.
Total Station was used for location of hanger points and the “One Model” was used for construction. Virtual Construction loaded the various trade information into the One Model for field coordination. Medical Gas Piping was installed by certified craftsmen and pre-fabrication practices were used in the shop shipping materials to the jobsite. The scale of this project required every hand on deck.
Hilti racks designed and installed to accommodate multiple trades, PODS of the patient tower restroom, patient headwalls for medical gas and electrical were all innovative technologies utilized in this project.
Schedule and budget were some challenges faced due to this extremely large project, but manpower was the biggest. There were several large projects going on in our area and we relied heavily on non-Tweet/Garot employees to perform. Our Tweet/Garot supervision was key to the completion.
Tweet/Garot’s scope of work for the project included pipe fitting, process piping for the breadcrumbs area using Morris pipes and clamps systems. Some welding required special craftsmanship, good layout knowledge and scheduling lead to a fast project completion.
We worked with the general contractor to schedule the work in each area due to the fast-paced schedule and the mass amount of different trade work that needed to get done. It was imperative that work was scheduled out to avoid trade stacking. Though the piping system was a very streamlined and simple system to put together, the hangers themselves required a specific design to be a food grade hanger as to not capture/collect any dust or bread crumb particles that could build up over time. Before we mobilized, we fabricated all hangers for the project in our shop. We then batched and labeled the hangers in a specific format so they corresponded to the markings that were made on each drawing. This way, when they arrived at the site, the foreman was able to pull the exact hanger needed for crews for the day, and they only had to make one cut on the rod. This was able to save us a significant amount of time in the field that would have been needed to measure, cut and fabricate these custom hangers.
