Featured examples that showcase Tweet/Garot’s experience and capabilities at customer locations throughout the United States.
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.
This is a 97,500 sq.ft. bed tower addition for MyMichigan Health Systems located in Alpena, MI. Tweet/Garot was brought on board as the design-assist partner after the original project came in over budget. We worked with the construction manager and the owner to get the scope of the work defined back into MyMichigan Health’s budget.
The three-floor addition consisted of operating rooms, a sterile processing department, prep/recovery rooms, labor/delivery rooms, isolation rooms, and standard patient rooms.
Some challenges from this project were the fast-paced schedule which included substantial pre-fabrication work. Despite these challenges, we were able to deliver a final product that left our customer satisfied.
Sheet metal, Pipefitting and Service Technicians were involved on this project. This project included the replacement of major HVAC Equipment including RTU’s, Boilers, and Chillers. Modification of existing HVAC systems, equipment stands and openings were modified to accommodate new equipment. This required special craftsmanship. Duct cleaning of the existing systems was also part of this project in an effort to provide clean air to the casino patrons. Tweet/Garot installed Bipolar Ionization on new and existing equipment and added additional filtration for cigarette smoke.
Utilization of newly developed technology such as Bipolar Ionization added filtration to eliminate pathogens and bacteria. Tweet/Garot also replaced existing boilers with high energy efficient boilers for overall energy savings.
Challenges faced during this project included a short completion schedule. The funding for this project came with a firm deadline for work to be completed, basically use it or loss it. Due to past experiences, the customer knew that Tweet/Garot could complete this project on time.
Delayed project deliveries shortened the allotted installation time. In addition, boilers needed to be installed before cooler months which further tightened our project schedule.
Despite COVID-19 challenges on the jobsite, the field crew had zero reported injuries.
Gundlach Champion, Clean Air Services, S & T Electric, Automated Logic Controls and complete Cover for insulation were all on the project team. COVID-19 relief funds were used to finance this renovation.
