Here’s to Another Fifty Years of Engineering ExcellenceThe entire world around us has been changed by innovative engineering professionals. James A Michener said, “Scientists dream of doing great things. Engineers do them.”

Engineers are the life-blood of any society. From smart buildings and the golden gate bridge to space travel and fast cars, or even the latest tablets, engineers have shaped the way our world works. Innovation is at the heart of what every great engineer does, so finding the balance between solving problems that need to be fixed, and being creative in order to do so is an important part of any engineer’s life. Finding creative solutions to real problems is what engineers do.

The ACEC/MN Engineering Excellence Awards (EEA) program provides a rare opportunity to acknowledge the many creative projects that member firms and engineers have worked on throughout the past five decades. This awards program recognizes the efforts of our members and their clients for their foresight and dedication.

Over the past 50 years, nearly 1,000 projects have been entered into the competition. These projects have ranged from the highly visible (Mall of America, Twins Stadium) to those that the public rarely even sees (wastewater treatment systems, soil stabilizations, environmental cleanups), yet have a dramatic effect on our lives. Every one of these projects--no matter how visible--makes our lives better in some way.

The EEA program has evolved over the years, but its underpinnings have remained the same from the beginning. Projects are solicited by the organization from engineering firms; clients must sign off on the entry to be accepted; a panel of judges made up of representatives of client groups judges the entries; and a banquet is held to honor firms and clients for their achievements. The top award winners on the state level (Grand Awards) are eligible to move on to the ACEC National

Alliant Engineering, Inc. I-35E MnPASS Design-BuildSt. Paul, MN

The $98 million design-build project reconstructed and widened 3.3 miles of three-lane divided highway. It included adding northbound and southbound managed lanes, the full reconstruction of one interchange, and the modification of portions of four other interchanges. The project also included the replacement of nine bridges, wetland mitigation, retaining walls, noise walls and the installation of tolling infrastructure to facilitate the future MnPASS Express Lanes.

Ames Construction was the lead contractor, and Alliant was responsible for all design elements on the project. The Ames/Alliant Team’s schedule limited traffic impacts to a 120 day window during each construction season, which was an average 48 days/season better than the competitors’ proposed schedules. Traffic impacts to the five urban arterials crossing I-35E were also substantially reduced through innovative techniques.

American Engineering Testing, Inc.U.S. Bank StadiumMinneapolis, MN

The U.S. Bank Stadium project exemplifies a collaborative effort from a strong, experienced technical team including American Engineering Testing’s (AET) geotechnical and environmental disciplines working closely with Mortenson, the newly formed Minnesota Sports Facilities Authority (MSFA), and the design team.

AET’s geotechnical engineers analyzed and provided buttress foundation recommendations to support extremely large thrust loads from the single roof truss system and self-retained backfill systems to reduce lateral loads on costly deep retaining walls. AET’s environmental services kept the earthwork on track; increasing the beneficial reuse of available soil and minimizing landfill disposal.

Construction of U.S. Bank Stadium was completed ahead of schedule and will have lasting benefits for the stakeholders, the engineering profession, and community as a whole.

Barr Engineering Co. West River Parkway High-Profile Landslide Repair

Minneapolis, MNIn June 2014, a record storm caused 10,000 square feet of the Mississippi River bluff to fail, burying West River Parkway and exposing hospital infrastructure. The Minneapolis Park & Recreation Board hired Barr to monitor slope and infrastructure stability and then design and observe construction of repairs. Work was complicated by the extremely steep slope, limited access, seepage, weak soils, and stability concerns. Barr integrated soil nails and five retaining walls to design a unified stabilization system and used low-vibration installation techniques to avoid causing additional slides. Completed under budget, the project helped ensure public safety without interrupting hospital operations. The parkway reopened for commuters and cyclists on September 1, just in time for the Twin Cities Marathon.

Short Elliott Hendrickson Inc. I-35W and Highway 96 Interchange - Ramsey County, MinnesotaArden Hills and New Brighton, MN

Economic redevelopment of a 430-acre inactive army ammunition site was a significant driver in advancing reconstruction of the I-35W at Highway 96 interchange in Ramsey County. In collaboration with multiple project partners, and under an extremely aggressive schedule, the County led efforts to evaluate multiple interchange designs that would accommodate a variety of additional users including local and regional travelers, commuters, bicyclists and pedestrians. An innovative diverging diamond interchange (DDI) configuration was selected as the preferred alternative from an operations, safety and mobility perspective.

Multiple challenges were overcome throughout design and construction including public acceptance, ADA accommodations and regional trail connections, zero right-of-way acquisition and the need to maintain full access along Highway 96 during construction. Significant agency coordination, public outreach and creative construction staging were critical factors in the success of the project.

SRF Consulting Group, Inc. Old Cedar Avenue Bridge RehabilitationBloomington, MN

Built in 1920, the Old Cedar Truss Bridge is a historic five-span, 865-foot-long, steel truss bridge crossing over Long Meadow Lake in Bloomington, Minnesota. Originally constructed as a vehicular bridge, it was converted to a bicycle/pedestrian facility in 1993, but closed in 2002 due to significant deterioration. The project goals included restoring pedestrian/bicycle connectivity to the regional trail system, meeting the Secretary of Interior’s standards for rehabilitation, and meeting structural loading and safety standards while minimizing future maintenance costs. To meet these goals and address challenges with access through the National Wildlife Refuge, SRF worked closely with stakeholders throughout design and construction. The rehabilitation work included steel truss repairs, substructure repair and reconstruction, deck and railing replacement, and repainting. Rehabilitation was complete September 2016.

HNTB Corporation The Historic Franklin Avenue Bridge RehabilitationMinneapolis, MN

The historic Franklin Avenue Bridge, built in 1923 and first rehabilitated in 1970, is a 1050-foot-long, five span, open-spandrel, concrete deck arch structure crossing the Mississippi River in Minneapolis, Minnesota. Advanced degradation warranted extensive concrete repair and full deck and spandrel cap beam replacement. The project applied Accelerated Bridge Construction techniques including Prefabricated Bridge Elements and Systems consisting of 43 precast spandrel cap beams, 350 deck panels, and 163 ornamental rail

panels to replace the bridge deck and spandrel cap beams under full closure between May 8, 2016, and September 1, 2016. Deck panels were connected with Ultra High Performance Concrete and overlaid with Premixed Polymer Concrete wearing course. These innovative techniques extended the life of the bridge and limited closure to just 116 days.

Stanley Consultants, Inc. Lake Delhi Dam

Lake Delhi, IA

When Lake Delhi Dam failed in 2010 the small Iowa community was devastated to lose the region’s major source of recreation and income. They rallied to rebuild, privately raising $1.7 million and taxing themselves for a $6 million restoration bond. The six years between the failure and completion of the new dam included four years of inspection, permitting, funding, public awareness, legislation and design. To meet modern criteria a labyrinth spillway replaced the failed earthen dam. The unique shape triples its capacity to pass water compared to a conventional spillway. Essentially unknown in the Midwest, the $13 million dam is the first of its kind in Iowa. The dam was recently put to the test by the lake’s fifth largest recorded flood. It performed flawlessly.

Stantec The Central Park Fountain and Ice Skating Loop

Maple Grove, MN

This former gravel mine in Maple Grove represented a unique opportunity to develop a destination community park. When it was time to design and build Central Park, Stantec served as the ice and aquatics consultant, designing two key recreational features – the ice skating loop and the aquatic fountain. Our team provided engineering services for the skating loop, the refrigeration plant, and the containment curbs and railings. Stantec also designed the aquatic fountain, piping, and equipment room. The 810-foot-long meandering ice skating loop, which accommodates up to 525 skaters, is the first of its kind in Minnesota and provides year round recreation. The 2,100-square-foot interactive fountain uses 67 multi-colored, LED lighted ground spray jets and unlimited programming capabilities to provide an impressive light and water show.

WSB & Associates, Inc. Elm Creek Dam

Champlin, MN

The Elm Creek Dam is a historical structure located in the City of Champlin that was originally built in 1880 and reconstructed in 1936. This dam was in need of replacement because the structure itself was deteriorating and the dam had inadequate capacity to accommodate the necessary flows to prevent upstream flooding.

The engineering challenge related to this project resulted from competing goals of historic preservation, upstream flood prevention, and addressing the varied interests of the regulatory agencies. The innovative engineering approach led by WSB resulted in a dam that achieved the goals of the regulatory agencies, improved flood protection and the ecology in the area, enhanced motorist and pedestrian safety, and created a community amenity.

Bloomington Local Road WayfindingBloomington, MN

Bloomington identified the need for an intelligent wayfinding system to manage traffic in its growing South Loop District. The Local Road Wayfinding project installed dynamic message signs and cameras on City streets. The complex design included a significant stakeholder coordination process and integration of the design with two related wayfinding systems. Alliant provided the City with professional services for design and construction.

The project provides real-time benefits by efficiently directing visitors to available parking and away from congested roadways. The system reduces fuel consumption and improves air quality by reducing the need for vehicles to circulate for available parking. The system was completed in October 2015, and provides the City with a tool to assist visitors to their destinations while balancing traffic on area roadways.

American Engineering Testing, Inc. & Anderson Companies Hamline Station Apartments

St. Paul, MNHamline Station is a great example of people, passion and partnerships coming together to address significant community and economic issues. Project for Pride in Living (PPL) promoted economic development, sustainability, and community livability by remediating environmental contamination on this long-blighted property and created large-scale affordable housing along the Green Line Light Rail Corridor in the Midway neighborhood of St. Paul, Minnesota.

Hamline Station was designed to provide affordable housing options, minimize emissions, increase energy and water efficiency, and promote public transportation.

Over the course of the project, over 14,000 tons of contaminated soils were encountered and dealt with. PPL collaborated closely with Anderson Companies and American Engineering Testing to ensure the project achieved its budget, schedule, and sustainability goals.

Bolton & Menk, Inc. Belle Plaine Overpass

Belle Plaine, MN

Belle Plaine is a rapidly expanding city split by a major highway, and was in need of safe connectivity to accommodate its growing population. Safety concerns had led to the closing of six crossing points, leaving one interchange as the only route for local residents to cross the highway.

An additional full interchange, estimated to cost over $12 million, was fiscally impractical. Bolton & Menk, Inc. worked collaboratively with multiple government entities to put together a plan that allowed the City of Belle Plaine to build a “right-sized” and locally funded overpass for the cost of $5 million.

The community has quickly adapted to the new, convenient traffic pattern, and the City is experiencing new economic development as a result of the improved accessibility.

Bolton & Menk, Inc. Trunk Highway 25 Downtown Corridor ImprovementsBuffalo, MN

The City of Buffalo and Bolton & Menk collaborated to create better, safer access to a more vibrant, pedestrian-friendly downtown through the Trunk Highway 25 Downtown Corridor Improvement project. Trunk Highway 25 carries over 13,000 vehicles per day, was plagued with many crashes, and underserved pedestrians.

Bolton & Menk addressed issues through a complete reconstruction. Key elements included a roundabout, narrower traffic lanes to accommodate a continuous two-way left turn lane, and two traffic signals. Utility design took into account historic buildings, access to businesses, and utilities moved from under the roadway.

Settlers Parkway, a new roadway and roundabout on the south side, connects Trunk Highways 25 and 55, providing critical connection between the regional roadways from the south, reducing congestion on Trunk Highway 25 through downtown.

Bolton & Menk, Inc. Trunk Highway 61 / Main Street ReconstructionRed Wing, MN

The City of Red Wing, Bolton & Menk, and MnDOT worked together to accomplish a successful street reconstruction project through the heart of Red Wing. Trunk Highway 61/Main Street provides crucial access to the community’s residential, commercial, and regional destinations; serving vehicles, trucks, bikes, and pedestrians.

MnDOT was planning a pavement preservation project. Bolton & Menk was hired for funding assistance to achieve the City’s goals for a complete reconstruction. The team worked to understand the City’s needs and desires, then developed reconstruction concepts that achieved those goals. Elements were added to enhance competitiveness and benefits provided by the project, including utility replacement, roadway corridor reconstruction, enhanced multimodal travel, and streetscaping elements. The project received the largest amount of CIMS funding available throughout the state.

Bolton & Menk, Inc. Sleepy Eye Lake Trail Project Phase 2Sleepy Eye, MN

The City of Sleepy Eye and Bolton & Menk worked to complete the final 1,800-foot stretch of a three-mile trail loop around Sleepy Eye Lake and provide a safe alternative to the TH 4 shoulder for pedestrian and bicycle traffic.

An innovative plan was implemented using a ring and grid system, allowing for easy maintenance and grass regrowth while withholding the weight of snow plows for snow removal. The ecofriendly design reduces the amount of road salt into the lake.

The project required filling one acre of the lake. Extensive coordination with the U.S. Army Corps of Engineers, DNR, and the Local Government Unit was key. The project met the City’s many goals and is now a vibrant lake trail for outdoor enthusiasts to enjoy.

Waconia Fountain Park Stormwater Management ImprovementsWaconia, MN

Waconia’s Fountain Park featured an aging storm water pond susceptible to flooding and not designed to provide adequate water quality treatment for the 60-acre urban watershed it drains. As a result, excess pollutant loading was being discharged into Lake Waconia, a popular and valuable community asset.

Bolton & Menk, Inc. presented a number of options for flood mitigation and improved storm water management, including sump manholes with baffles, pond outlet control structure, bioretention areas, tree grates, iron enhanced sand filter, and permeable pavement.

The City elected to implement all of the recommendations simultaneously. Through creative value engineering, the flooding problem was solved and a blighted, contaminated pond site in the heart of Waconia was transformed into an attractive community gathering place.

Bolton & Menk, Inc. Water Treatment Backwash Reclamation Project

Mankato, MNThe City of Mankato and Bolton & Menk, Inc. identified a significant source of water that could be reclaimed for drinking water. The backwashing process required to keep ultrafilter membranes clean at their major water plant was producing 450,000 gallons per day that could be returned to the drinking water supply. Additionally, this relatively clean water discharged to the sanitary sewer added unnecessary flow at the wastewater facility. A solution was engineered that converted backwash holding tanks to reclaim tanks, avoiding the need to discharge to the sanitary sewer. The amount of water saved is equivalent to the daily use of 5,000 people. The cost and sustainability benefits of this project are more than enough to justify and offset the $1 million cost.

Braun Intertec Corporation Trunk Highway 53 Temporary Rock Causeway

Virginia, MNDuring construction of Trunk Highway 53, Braun Intertec designed a temporary causeway to provide a stable platform for pier construction and steel erection. The design varied up to 110’ in depth, with 5’ exposed above the water line and also addressed many complexities, such as varied surface loading of construction equipment and shoring towers, as well as strength changes resulting from rock at lower elevations crushing from the weight of the rock above.

Since the construction was performed by push and plunge methods, the slope angles of the rock below the water surface were surveyed using sonar to determine where re-design would be required. The top of the platform used geogrid to increase bearing pressures and provide a stable working surface, allowing construction to begin.

Houston Engineering, Inc. Grand Marais Creek Channel Restoration

East Grand Forks, MN

The Grand Marais Creek Restoration project addressed a challenge that began around the same time as the first world war. A cutoff ditch had been constructed that led to significant problems along Grand Marais. By restoring the natural six-mile outlet, the Red Lake Watershed District and its partners restored aquatic habitat, wetlands, and native prairie; reduced the average annual 700-ton sediment loading that the cutoff ditch deposited into the Red River; provided drainage for agricultural land; and constructed unique structures over the channel out of repurposed railroad cars. All this was accomplished by coordinating with private landowners; local government unites; and local, state, and federal entities.

Clark Engineering Biogas LeeuwardenLeeuwarden, the Netherlands

The Dairy Campus of Wageningen University is the world’s top-ranked agricultural research university. Its waste-to-energy plant converted manure into biogas using traditional anaerobic digesters. The traditional system failed to yield adequate biogas and became obsolete.

Clark Engineering and Evergreen Energy developed a new patented bio-catalytic conversion system and patent-pending waste-to-energy conversion technology to retrofit the plant. These new technologies produce at least 50% more useable biogas than any other technologies in the world.

This digester of the future allows high-efficiency conversion of organics into clean energy. The plant produces 60% more biogas at lower cost compared to the original system. It produces electricity for 1,700 residences and heats 700 more. In five hours, it generates enough energy for an entire household for one year.

Southwest Reconnection Project - Carver County, MinnesotaChanhassen and Shakopee, MN

The fundamental goal of the project was to resolve costly seasonal road and river crossing closures of the Highway 101 Minnesota River Bridge that connects Carver County to Scott County through a lower cost, high benefit improvement. Minimizing traffic conflicts and improving operations along Highway 61 was also important for vehicles and non-motorized users alike.

The solution involved constructing a new, 4,200 ft. long bridge across the floodplain to raise the roadway out of the 100-year flood elevation, and reconstructing the Highway 101 and Highway 61 “Y” intersection as a roundabout in place of three signalized intersections. One of the primary challenges involved maintaining traffic throughout construction with limited river crossing options. Other complexities included incorporating a multiuse trail connecting to regional trails, deep muck excavation, and a unique archeological discovery.

The St. Anthony Stormwater Treatment and Research System project was developed through a collaborative effort involving the Cities of St. Anthony Village and Minneapolis as well as Hennepin County and the Mississippi Watershed Management Organization. The project was initiated to improve the quality of stormwater runoff from approximately 600 acres of fully-developed urban land. The complex and innovative design includes two confined treatment chambers. The primary treatment chamber includes an aluminum swirl chamber and flow controls. The secondary treatment chamber allows for the testing of emerging technologies in order to determine their effectiveness. One project goal was to inform and educate the public regarding stormwater best management practices. This was accomplished through website posts (including an educational video), press releases, and an onsite construction camera.
