< Back Previous Next < Back American Engineering Testing (St. Paul, MN) Saving limited valuable real estate space Year Completed: 2018 American Engineering Testing, Inc. Headquarters is located in St. Paul, Minnesota. They were retained to investigate Stormwater mitigation installations that had used TDA as a water storage material. They recognized the cost efficiencies of an aggregate that was very low cost, less than $5.00 per compacted cubic yard delivered to their job site. This new aggregate can retain 14 cubic feet of water in each cubic yard of TDA installed. This Sustainable new Aggregate material is specified by ASTM as an ASTM 6270-B material and is made from discarded tires. In 2018, American Engineering decided to increase the parking space capacity at their St. Paul location. They historically had an open pond serving as a stormwater device, so in their new property plan, they decided to convert the green space and open pond into more parking spaces. To continue to meet the stormwater requirements they chose to install an under parking lot infiltration gallery. They also choose TDA as the storage media for their site. Frattalone Companies did the site construction and the TDA Installation under the parking lot. First State Tire/TDA Manufacturing was the supplier of the ASTM 6270- B material. The existing pond with TDA before the stormwater system was put in place and the two separate parking lots became one. Yet another benefit of using TDA is the eco-friendly component of saving thousands of tires from a landfill.

< Back Stearns Bank (Albany, MN) Parking lot water flow problem solved Year Completed: 2019 Previous Next

< Back Previous Next < Back American Engineering Testing (St. Paul, MN) Saving limited valuable real estate space Year Completed: 2018 Stearns Bank N.A. Equipment Finance Division in Albany needed to add parking lot space for employees and visitors. The new space, however, is more than just a place to park vehicles. Underneath the layers of asphalt and Class 5 gravel, around 95,000 shredded and compacted scrap car tires, or tire-derived aggregate (TDA), serve as a filter and drainage system for storm water runoff. “When you add more parking, you add more flat surfaces and you have more water to deal with,” said Shawn Robinson, superintendent with Miller Architects & Builders. Storm water ponds are constructed to mitigate and filter excess water runoff. Holding ponds, however, often require space that could be used by business and home owners for other purposes. “Open water ponds are a mosquito breeding ground,” said Curt Hoffman, TDA specialist with TDA Manufacturing. “They can also be dangerous to kids. Kids like to climb fences.” Miller Architects & Builders out of St. Cloud designed and oversaw the project, while TDA Manufacturing, a division of First State Tire based in Isanti, provided the TDA. Craig Bardson Excavating Inc. of Albany supplied the gravel and did the compacting, while Knife River did the paving. All the water will come off the parking lot and flow into the drainage system underneath. “Not only does the TDA slow water down and deal with the capacity, it treats it, as well,” Robinson said. Hoffman agreed. “The carbon in the rubber and the steel banding in the tires attracts phosphorus, nitrates and other contaminants,” he said. Also, TDA is less expensive than traditional aggregate and it lasts longer. “The TDA provides a capillary break,” he said. “It can withstand freeze-thaw cycles and you don’t have to worry about fissures or cracking.” First State Tire shreds about 2.5 million tires a year, creating 65,000-75,000 cubic yards of aggregate that is applied to various projects, including storm water management, roadway bedding, embankment support, trails, parking lots and other purposes. “TDA has been around for a long time, we’ve been producing it for 30 years,” Hoffman said. “It’s starting to gain popularity through education and workshops. If it’s done right, tires can be environmentally friendly.” As millions of tires are produced and discarded each year, a portion of them will be reused for other purposes, such as aggregate, which in turn preserves resources. It is one step closer to a greener future.

< Back Previous Next < Back American Engineering Testing (St. Paul, MN) Saving limited valuable real estate space Year Completed: 2018 The site of the old Midway Stadium, 1771 Energy Park Dr., St. Paul, is home to one of the largest civil engineering applications of Tire Derived Aggregate (TDA) in Minnesota. Over one million tires, or approximately 20 percent of a year’s worth of discarded tires in Minnesota, are finding new life protecting the Mississippi River from stormwater runoff. Where people once tailgated before the baseball game, business have now set up shop in a 190,000-square-foot commercial and light industrial office warehouse project. Unbeknownst to perhaps all of the tenants and customers, their parking lot is resting on an underground stormwater filtration and storage system made from TDA. The tire shreds’ job is to capture the sediment and store the water for slow absorption back into the area. Developer Asked to Step Up to the Plate with Response Action Plan The Saints baseball team had played here for 22 years. In those days, water ran over the surface to a seven-foot-diameter pipe that dumped water and sediment directly into the Mississippi River. Because the land was once a landfill for the State Fairgrounds, the St. Paul Port Authority required a Response Action Plan to remediate a site that is a potential source of pollution for ground and surface waters. We’re not talking about a small landfill. Today, the 12-day-long Minnesota State Fair is one of the region’s most widely attended tourist activities, drawing about 1.8 million visitors a year. It’s one of the nation’s biggest fairs. The fair is located next to the Midway Stadium site on 320 acres. Extensive cleanup of the site occurred in 2015. At the beginning of 2016, the stormwater management system was installed. LHB Corporation designed the stormwater management system using TDA supplied by First State Tire Recycling, Isanti, MN. A SAFL Baffle, pervious pavers, and approximately 30,000 cubic yards of TDA work together to pre-treat water by removing sediment. The system is designed to infiltrate the runoff volume from a 100-year storm event. LHB Corporation project documents describe the advantages of using TDA as fill for stormwater systems: “The use of TDA as a storage facility for stormwater treatment provides an environmentally safe reuse of tires that would otherwise be discarded as waste.” The project documents explain, “Tire derived aggregate offers a reduced cost alternative to the typical stone aggregate and chamber systems that are commonly used for below grade stormwater storage. In addition to conserving natural resources, TDA can greatly reduce the cost of construction for underground systems.” Monte Niemi, CEO of First State Tire Recycling, says many developers prefer to have their stormwater systems be underground, as it saves valuable real estate space. “The use of tire derived aggregate in civil engineering has its roots in road construction and site foundation stabilization,” Niemi said. “Heavy developments on top of TDA have proven successful due to its unique engineering properties.” Niemi describes the unique properties as lightweight with high shear strength, large void space and good thermal insulation. Tires Aid in Proven Design With the assistance of the Minnesota Pollution Control Agency and others, the St. Paul Port Authority has turned 21 polluted and often abandoned inner-city sites into environmentally friendly business centers. In 2010, the St. Paul Port Authority installed an innovative, state-of-the-art stormwater system that set a precedent in sustainable, or “green,” engineering. Formerly the home of 3M Co. factories, the land now hosts 650,000-700,000 square feet of new buildings. Within the land, engineers connected new, 10-foot diameter metal culverts to the Phalen Storm Water tunnel which was already present. As backfill to surround the metal culverts, 7,725 cubic yards of TDA was installed. The system now eliminates more than 90 percent of the runoff sediment from 163 acres of St. Paul East Side that previously flowed untreated into the Mississippi River. The project won numerous awards, including the ACEC Grand Award and the 2012’s People’s Choice Award in ACEC’s Engineering Excellence Award Competition. About the Contractors The Midway Stadium site involves United Properties, LHB Corporation, R.J. Ryan Construction, and Carl Bolander & Sons Corporation.
