Firm: Barr Engineering Company
Project: Dam Removal and Fish Passage Creation
Location: Spearfish,SD

The site of the former Savoy Dam,constructed in 1917,is a favorite access point to Spearfish Creek,which has a trout population of approximately 3,500 fish per mile and is a popular attraction in South Dakota’s BlackHills. Barr worked with South Dakota Game, Fish, and Parks to replace the existing dam with a natural-looking structure that would allow fish passage to portions of the creek inaccessible to upstream fish passage since

Firm: Bonestroo
Project: Dam Removal and Fish Passage Creation
Location: Cottage Grove,MN

VISSIM,a new traffic analysis software program, was used to help the design team build a visual simulation model that demonstrated the full operation of the proposed project, which,since its completion last October, has kept traffic in thea rea moving smoothly for the first time in more than a decade.

Firm: Earth Tech,Inc.
Project: Water Treatment Plant Improvements
Location: Hutchinson,MN

To address both source water ammonia and copper corrosion, Earth Tech staff pilot-tested membrane-softening for hardness reduction using a filter element with the ability to reject ammonia at the lowest possible osmotic pressure.To address ammonia removal on the side-stream process, biologically active filtration was pilot-tested for iron, manganese and ammonia removal.

Firm: Ericksen, Roed & Associates, Inc.
Project:  Cobalt Condominiums
Location: Minneapolis,MN

The trusses on alternate floors span between the columns located only at the exterior, with spacing that allows corridors and other passages, greatly increasing flexibility in space planning on all levels,including parking.The truss system’s large bays of precast modular structural members expedited the structure’s erection,and provided an early enclosed shell,which expedited occupancy.Erection directly from truck beds eliminated lay-down space,and met the City’s requirement that streets remain open to public traffic.The ER-POST™ system was the most economical option, and provided many other benefits,including quick installation.

Firm: Stanley Consultants
Project: Saving St.Anne’s
Location: Grand Forks,MN

The U.S.Army Corps of Engineers (USACE) asked Stanley Consultants to develop a plan to save St.Anne’s. The firm recommended constructing a floodwall around the outside of the building, disguised as a porch. To meet the requirements of the local Historical Commission,the floodwall could not touch the building’s exterior, however in order to make it look like a porch,it needed to hug the varied exterior contours, wrapping around every corner and mimicking the building’s architectural features.

Project: Midtown Greenway Bridge
Location: Minneapolis, MN

The first of its kind in Minnesota, the bridge design is a graceful and striking engineering solution to a set of complex physical constraints.In Architecture Minnesota,Phillip Koski, (AIA) described it: “Composed of an impossibly slender slab of concrete tied together with a spider web of cables to a tilted mast of tapered steel,the Greenway Bridge at first seems a willful, yet artful, extravagance.”
