Featured examples that showcase Tweet/Garot’s experience and capabilities at customer locations throughout the United States.
DTE – Matsches Dairy Farm
Tweet/Garot was awarded the Renewable Natural Gas project located on the property of Matsches Dairy Farm in Birnamwood, WI. With the completion of multiple other RNG projects around the Northeast portions of Wisconsin, this project fit well within the limits of Tweet/Garot’s capabilities.
This RNG project consisted of setting a large amount of equipment skids in which were placed around (2) new aboveground digesters. Both underground connection piping to the existing farm along with all of the associated aboveground piping to complete the necessary ties to each piece of equipment was performed by Tweet/Garot personally. A few unique piping systems installed included the following:
- Raw Manure
- Tail Gas
Equipment setting was a large portion of the project which consisted of multiple critical crane picks based on the sheer size and weights of the items and their proposed locations on site. A list of equipment installed includes the following:
- Ferric Hydroxide Dosing System
- Boiler Skid (Prefabricated Building)
- Biogas Storage Membrane with Air Blowers
- Biogas Aftercoolers
- Vacuum Pump Enclosure
Approximately ½ mile or 2,000 linear feet of underground pipe was installed and about the same in above ground pipe for the project. In total, close to 1 mile of pipe, or 5000 linear feet, was installed over 11,170 manhours.
Challenging weather conditions along with shifting project schedules with equipment delivery dates being pushed out caused us to adapt our plan almost daily. Prefabrication of the large bore pipe and structural supports helped bring the project to a successful on time project completion allowing the owner to successfully start their renewable natural gas extraction from Matsches Farm.
Paper Converting Project
The paper converting site’s vision was upgrading and adding converting lines to maximize paper towel and toilet paper output. The owner came to our team of experts at Tweet/Garot along with three additional industry partners, in the conceptual phase of the projects to help put together a price based on best practices from previous projects.
The team was handpicked because of our successes together to complete projects on time, which can be a challenge for large mills like this when located in remote areas with limited workforce. Tweet/Garot was able to keep our core group of traveling workers, who have completed similar projects previously, and roll them into the project. This was a key factor in ensuring this project’s success for the owner’s needs.
This site added converting lines for two separate products: paper towel and toilet paper. Each of these projects included demolition of the old mechanical utilities as well as installation of:
- Building Ventilation
- Dust Collection
- Trim Collection
- Cabinet Cooling
- Potable Water
- Mill Water
- Compressed Air
- Process Drains
Between these scopes of work, Tweet/Garot was onsite for approximately 10 months.
Hy-Vee is an Iowa based chain of supermarkets with locations in the Midwestern and Southern United States. Currently there are more than 280 locations in Iowa, Illinois, Kansas, Minnesota, Missouri, Nebraska, South Dakota, and Wisconsin.
In late 2021, Hy-Vee expressed interest in a recently vacated building located in Ashwaubenon, Wisconsin. On November 8, 2022, this nearly 125,000 square foot store opened. It is the fourth location in Wisconsin and is the largest in the chain by square foot.
Tweet/Garot was subcontracted under Boldt Construction to handle the plumbing and HVAC scopes of work. Over the course of construction, the building was completely gutted and remodeled. Crews from different trades worked closely with each other to coordinate activities to ensure the expected completion date was met. With manpower and supply chain issues, this was no easy task, but Tweet/Garot was able to deliver.
Key components of our work:
- 19 new roof top units were installed to handle the heating and cooling needs of the building.
- 11 kitchen hoods, 14 exhaust fans, and 4 make-up air units were installed for proper exhaust and ventilation of new kitchen equipment to prepare items in the new food court.
In total, Tweet/Garot worked 12,225 hours with zero injuries on this beautiful project.
Ashwaubenon residents, as well as visitors, now have a new and modern option for their grocery, dining and pharmacy needs for years to come.
Menzner Hardwoods is a leader in the hardwood industry, from moldings and accents to surfaced boards and stair parts.
Tweet/Garot was chosen for this dust collection rebuild project because of a continued customer relationship, along with our ability to meet the customers’ requirements. One critical requirement included installation during minimal down time for production as well as utilizing the existing dust collection unit.
As many fittings as possible were prefabricated and the majority of the dust collection ducting was installed during production hours. This, paired with the fast-paced schedule, made for a challenging project. Tweet/Garot, however, was able to meet the customer’s requirements and complete a smooth project close-out.
Zero injuries occurred throughout this project.
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.
