Award Winning Projects
The Downtown East Development exemplifies an innovative effort from a strong, experienced technical team including American Engineering Testing, Inc. (AET) and Erickson Roed and Associates (ERA). The team worked closely with project stakeholders, including their client Ryan Companies US, Inc., to complete the 12.5-acre development in downtown Minneapolis. The project brought a much-needed green space to the downtown area alongside wide development connecting central downtown with the new U.S. Bank Stadium, the Mill District and Elliot Park neighborhood. The innovative techniques developed and implemented by AET and ERA related to urban fill identification and reuse, floor levelness and drilled pier shafts contributed to the timely completion of the project. These practices will have an impact on building design and site development into the future.
Southeast Wadena Street & Utility Improvements
Bolton & Menk, Inc.
The southeast portion of Wadena was experiencing poor infrastructure conditions and inadequate traffic capacity. Bolton & Menk prepared extensive preliminary survey and evaluated existing sanitary sewer, watermain, storm sewer, and transportation infrastructure for condition and capacity to meet future demands. Approximately 16,000 feet of sanitary sewer, 16,000 feet of watermain, and 5,000 feet of storm sewer was reconstructed in addition to stormwater treatment basin construction and 35 blocks of residential and commercial street reconstruction. The project included redesignation of CSAH 50 and CR 103 as state aid. Successful funding applications resulted in grants and a low interest loan to help the city improve its current and future traffic flow throughout the southeast area and enhance municipal utility system operation and performance.
The second extradosed bridge in the country represents a feat of engineering and political will. The largest bridge project in Minnesota history, the St. Croix River Crossing traverses a federally-protected waterway, requiring Presidential authorization to design and construct. As a result, the project included significant environmental considerations, such as visual quality elements that allow the bridge to blend into the environment, strict drainage requirements and enhanced best practices during construction. The HDR team’s process decreased the bridge’s structural complexities during construction, including approach structure geometry and eliminating two towers from the main span. The new bridge removes traffic from the historic lift bridge, reduces congestion in scenic Stillwater, provides faster access to jobs in the Twin Cities and has spurred economic development in western Wisconsin.
United Methodist Church of the Resurrection
HGA Architects and Engineers
The Church of the Resurrection in Leawood, Kansas, expanded their existing worship and mission-based facility with a 140,000-square-foot building that successfully balances the contradiction of an intimate, individually scaled sanctuary that seats 3,500 people. The innovative solutions, driven by the complex elliptical building geometry, include the layout and manipulation of an elliptical grid system, the development of a practical lateral wind load application to a non-rectilinear shape, the use of new analytical modeling techniques to mitigate balcony vibration and assure occupant comfort, and the integrated design and detailing of structure within an art form. The Church plans to use this new facility as a tool through which they will reach future generations, change lives, and transform the community.
Roosevelt Bridge Rehabilitation
The historic Roosevelt Bridge in the City of Austin is a two-span, barrel-arch structure. The bridge is significant for its unusual combination of concrete arches with a masonry substructure. Its aesthetics reflect the skills, artistry, and trade methods involved with the project during construction in 1933 and 1934. Recognizing its historic importance, Mower County, assisted by LHB and Mead and Hunt, the Engineers of Record and Historians respectively, sought for a complete rehabilitation of the bridge.
The limestone heavily faced the elements for eighty years. To maintain structural integrity, over 80% of the railing stones and over 50% of the headwall and arch stones were replaced. Assuring the replacement stones matched the historic stones in composition, craftsmanship, and pattern, was essential to the project.
Sperry Communication Tower
Short Elliot Hendrickson Inc.
The Sperry Communication Tower, by its planned design, represents a new landmark for the City of Eagan. The new 178-ft. tower focuses on carrier use objectives including technician access, and for the City a reduction of maintenance costs and allowance for revenue generation, while making a highly visual and unique statement on the City’s landscape. The lighting component features 112-4ft. linear LED fixtures and six flood luminaires that wash each concealment panel and level with static or variable color. SEH worked directly with stakeholders over the course of two years to develop an implementation strategy for the design, specifications and final construction, which also included redevelopment of tenant underground utilities. The communications tower allows for immediate capacity for six telecommunication tenants, and expansion to seven.
Lake Dehli Dam
Stanley Consultants, Inc.
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.
Central Park Fountain and Ice Skating Loop
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.
Douglas Trail Substation
When Epic Systems Corporation approached the City of Rochester, Minnesota, to request a substation on an aggressive deadline, Rochester Public Utilities (RPU) collaborated with Ulteig to strategize a solution. The Douglas Trail Substation was to be built on a small triangle of land surrounded by a highway, the new Epic Systems data center, and the Douglas State Trail.
To allay community concerns, Ulteig’s plan utilized a low-profile substation design and a screening wall adorned with a decorative finish. Ulteig utilized photographs from the site to develop a 3D computer model of the substation based on preliminary design. The City of Rochester shared renderings of that model in community meetings to address resident concerns. RPU applauded Ulteig for exceeding expectations and for its valuable contributions to onsite construction.
