52nd Engineering Excellence Grand Award Winning Projects

Westminster Presbyterian Church Historical Renovation & Expansion
AKF Group LLC

Built in 1896, Westminster Presbyterian Church’s increasing program demands required a 55,000 SF expansion and extensive renovations. AKF provided MEP/FP conditions assessment and design, energy modeling, architectural code consulting, and commissioning. All new systems were seamlessly integrated with existing infrastructure while maintaining the church's original gothic architecture. Westminster’s mission to demonstrate environmental leadership inspired AKF’s rainwater harvest system. With it, Westminster became the first building in Minneapolis to use stormwater for flushing toilets. AKF also realized Westminster’s goal for an acoustically superior performance space. Not only were all challenges overcome, but the project was completed by the church’s Christmas 2017 deadline. Everything was accomplished on a tight urban site with little staging area and the church remaining operational seven days a week throughout project duration.

TH 169 Nine Mile Creek Design-Build
Alliant Engineering, inc.

The $60 million Trunk Highway 169 Nine Mile Creek Design-Build project replaced an aging bridge across the Nine Mile Creek Basin in Hopkins and Edina, Minnesota. The bridge was demolished and replaced with a causeway through the floodplain. The causeway is constructed on an innovative ground improvement system which integrates controlled modulus columns with a load transfer platform to bear the weight of the infrastructure over the deep organic soils.

Ames Construction was the lead contractor and Alliant was responsible for all design elements. The causeway opened to traffic in Fall 2017, one year after award and over one month ahead of schedule. Soon an elevated trail could meander through the scenic area and cross under TH 169 near the creek itself.

 

Trunk Highway 210 Design-Build
Barr Engineering Co.

In June 2012, over 10 inches of rain fell in 24 hours in northeastern Minnesota, causing over 70 slope failures along 3.5 miles of Trunk Highway 210. For its $22.8 million highway reconstruction project, the Minnesota Department of Transportation selected the design-build team of Barr Engineering Co., Veit & Company, and SRF Consulting. Barr identified innovative, cost-efficient design methods to repair 74 slope failures. Our stabilization solutions blend with the natural surroundings and help protect fish and wildlife habitat. Barr also developed a remote real-time monitoring system, which continues to verify the integrity of the highway and surrounding slopes, and a cultural-resource-protection plan to minimize disturbance of the historic Grand Portage Trail during construction. The highway reopened in October 2017.

The Promenade of Wayzata
LHB, Inc.

The Promenade of Wayzata redevelopment project transformed the blighted 14-acre Wayzata Bay Center mall into a vibrant, green mixed-use community of six city blocks.  Extensive pedestrian-friendly sidewalks, gathering spaces on green roofs, and a variety of landscaped spaces offer an inviting destination for all.

Anchoring the east end of Downtown Wayzata near the shores of beautiful Lake Minnetonka, this project’s cutting-edge stormwater management system went to dramatic efforts to reduce runoff quantity and improve runoff quality for downstream water bodies, including the lake, Minnehaha Creek, and the Mississippi River.

Constructed over a former wetland, the site’s organic soils, shallow groundwater, and other significant site constraints required creative engineering to support the buildings and infrastructure needed for the owner’s programming and for an economically viable project.

Minneapolis Armory Renovation
Mattson Macdonald Young, Inc.

The Minneapolis Armory has served many purposes in its 82-year history.  Built for the National Guard, it has been a venue for the Minneapolis Lakers, concerts, and a parking structure.  To return the site to a social arena, the Armory was renovated by Swervo Development.

The renovation included the addition of a new floor above two existing parking levels, two balconies along each side of the venue, and over two dozen wall openings to connect previously isolated areas.

Mattson Macdonald Young was the Structural Engineer of Record for the renovation.  Following a thorough structural assessment, work included:

  • Reinforcement of existing concrete frames supporting a new floor, mezzanines, and openings
  • Design of steel-framed floor and balconies
  • Reinforcement of existing 200’ steel roof trusses to support upper mezzanines and entertainment rigging

Nine Mile Creek Regional Trail
Short Elliott Hendrickson Inc.

The 6.1 mile Nine Mile Creek Regional Trail (9MCRT) segment in Edina fills a critical gap of the overall 15.3 mile trail. This portion of the trail presented a number of design and construction challenges. It is adjacent to private/commercial properties, runs through Nine Mile Creek wetlands, woodlands and floodplains, and crosses other significant developed infrastructure including MnDOT trunk highways 62/100. Creative design was required to incorporate the trail over wetlands and near developed areas. Unique features of the completed trail include timber boardwalks near Nine Mile Creek, a tunnel under 70th Street, and pedestrian bridges over the trunk highways. The success of the project was also the result of significant agency coordination and communication. The 9MCRT now provides unique recreational opportunities to its users.

 

St. Anthony Parkway Bridge over BNSF Northtown Yard
Short Eliott Hendrickson Inc. & Parsons Corporation

The City of Minneapolis needed to replace a historic 85-year-old bridge that was non-redundant and in deteriorating condition over a busy railyard. An innovative approach was required to replace this bridge without disrupting the active railyard below. Through coordination with the railroad, the team used an incremental launching process and a unique launching system to assemble a 305 ft. steel truss bridge span off-site and slide it into place over the tracks. This was done in four-hour construction windows to keep the mainline tracks active. Features of the replacement bridge include an innovative, one-of-a-kind main span truss with internal redundancy measures. The end result is a new bridge that has innovative technical elements while preserving the legacy of one of the City’s most historic neighborhoods.

Zumbro River Restoration
Stantec

In 2010, flood water breached Lake Shady Dam on the Zumbro River, severely damaging the dam and downstream bridge. Stantec worked with Olmsted County and Oronoco, planning to repair the bridge, remove the dam, restore the upstream reaches of the Zumbro River, and create a Park Master Plan in the lakebed. Project goals included restoration of the river’s ecological health and natural beauty while creating new recreational opportunities for users. Stantec prepared an Environmental Assessment Worksheet and Preliminary Engineering Report that included, hydrologic/hydraulic analysis, dam removal and construction of a rock arch rapids, river restoration, wetland impacts, and recreational trails. Stantec completed final design and worked closely with MnDNR and the contractor to construct the project within tight budget constraints and a difficult physical environment.
