Minnehaha County Structure Replacement
Minnehaha County, SD
Two existing structures at a drainage crossing along County Highway 126 in Minnehaha County, just northwest of Crooks, were considered structurally deficient and functionally obsolete. Banner utilized its experience, expertise, and capabilities to provide complete design and construction-related services including feasibility studies, planning, design, construction contract administration, and construction observation for a replacement structure. Several bridge options were evaluated during design for functionality and cost, ultimately selecting a box culvert as the best alternative.

Brookings County Highway 77 Structure Replacement and Approach Grading
Brookings County, SD
At the southern end of Co. Hwy. 77 in Brookings County are two bridges: one crossing the main channel of the Big Sioux River, and another smaller overflow structure. Both structures (with portions built in 1925 and reconstructed in 1940) needed replacement. Brookings County applied for replacement grants through the SDDOT BIG program for both structures in December 2016. The smaller overflow structure (89’-6” Three-Span Continuous Concrete Bridge) was awarded a replacement grant in that round of funding. To keep the main crossing bridge (246’-0” Four-Span Prestressed Girder Bridge) on the same schedule as the overflow structure, a “Bid Ready” BIG application was submitted the following December, and the project was awarded a grant. The pair of bridges were let for bidding in the fall of 2018 with construction planned for the 2019 season. The construction completion date was later revised to the fall of 2020 after prolonged flooding and high water prevented work during the 2019 construction season. The smaller overflow structure is complete, and construction on the larger structure is underway.

Daktronics Skywalk
Brookings, SD
The Daktronics skywalk is an enclosed exterior walkway connecting two buildings at the Daktronics headquarters campus in Brookings. The skywalk extends from the northeast corner of Building 6 to the southwest corner of Building 2 at the top floor of both buildings. The interior of the walkway is 9' wide by 9' tall, approximately 180' in length. The structure consists of two separate prefabricated steel pedestrian bridges with 72' main spans and cantilevered ends. There are three precast concrete columns supporting the walkway. The finish of the precast column closely matches that of the existing buildings. The structure is enclosed on the sides and underside with 2.5" insulated metal wall panels with finishes that complement existing buildings. The floor is cast-in-place concrete on metal form deck. The roof is acoustical metal deck with insulation and a 90 mil EPDM membrane.
Early in the design and planning process, it was determined that utilizing shop-fabricated pedestrian bridges would be the simplest method to span between the two buildings. Due to the lead time for a prefabricated bridge structure, a design-build process was adopted and the contractor was brought on board so that the critical elements could be procured to maintain the desired schedule for completion.
Accommodations were made to allow for the installation of one of Daktronics display systems on the southeast exterior face of the walkway at a later date.

Brookings County Structure Replacement
Brookings County, SD
Two existing structures on County Highway 7 (north of Bruce, SD) had reached the end of their serviceable life and required replacement. Banner’s team performed the initial site surveys and hydraulic analyses to determine replacement structure types and sizes. After the replacement structure types and sizes were selected, Banner performed the final design of the replacement structures and preparation of the construction plans, including approach grading and guardrail.

Flair Fountains
Various, USA
Water features add a strong focal point or calming presence to a businesses, green spaces, and most any public gathering area. Banner has provided structural support services to Flair Fountains, located in Minneapolis, MN, for the structural design of several fountains throughout the Midwest. From the base of the "Legacy Ship" fountain located just outside the new Vikings Stadium to the stately fountain located on the green space of the University of St. Thomas, these fountains convey the aesthetic of the spaces they occupy. Banner is excited to have been a part of these outstanding projects!
