Featured examples that showcase Tweet/Garot’s experience and capabilities at customer locations throughout the United States.
Door County Medical Clinic – Whole Hospital Water Softener & PRV Upgrade
Door County Medical Clinic is an integrated medial center providing a wide range of specialties in the Door and Kewaunee communities.
The medical facility was experiencing issues with city water, including low pressure as well as very hard water. Their existing softener system was limited to only treating the hot water system. Tweet/Garot engineers and the project foreman, with his extensive site experience, talked through solutions to offer. We partnered with a local water softener provider and through collaboration with Tweet/Garot engineers, a solution was provided for whole hospital water softening for domestic cold and an upgraded domestic hot water system. Our water softener partner and Tweet/Garot’s engineering group also reconfigured a design solution to the domestic water pressure issue from the city with a new PRV system and bypass.
Plumbing and HVAC trades worked together due to the extensive stainless-steel piping required. Tweet/Garot’s fabrication shop utilized shop-controlled prefabrication for bolt up and assembly in the field, eliminating hot work or onsite fabrication.
Zero injuries occurred throughout this project.
Heartland Farms is a producer of potatoes for mostly chip manufacturers. Tweet/Garot was responsible to supply and install equipment for transferring and handling of whole potatoes from harvest warehouses to trucks for shipping to manufacturers. Load capacities range from 120,000-500,000 lbs./min.
Scopes of work include:
- Telescopic truck loading conveyor structure and system: 4-systems between Hancock and Bancroft
- Live bottom bins for mix and blend: 3-multi bin systems between Hancock and Bancroft.
- Transfer and incline conveyors: 100 plus conveyors
- Scale conveyors: 4-conveyors between Hancock and Bancroft
- Distribution and divert conveyors: 3-multi bin systems between Hancock and Bancroft
- Dewatering conveyors
- Flume fabrication and install: Including diverts
- Access platforms, stairs, ladders, crossovers and runways
- Equipment structures and supports
- Engineering, design and CAD support Including thru-put and load clarification
- Material and component selection assistance
Tweet/Garot designed and installed equipment rigging and setting of multiple systems for cleaning and sorting including:
- Flooding rock and debris systems
- Drum washers, brush washers, and dewatering felt roll conveyors
Despite the large scale process Tweet/Garot was faced with on this project, the job was completed in a timely manner and exceeded the customer’s satisfaction standards.
Clintonville High School/Middle School
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.
