Part II: 16 Great Projects from Affinis’s 16 YearsPosted on Wednesday, April 19th, 2017 by Peggy Amor

To commemorate our 16th anniversary, we’re sharing a project for each of the years we’ve been in business. Last week, we featured some from our first eight years. Today, you’ll find examples of our work from 2009 to 2016 below.
I-470 View High Drive to Douglas & Route 50 Interchange, Missouri Department of Transportation
This was a collaborative project that included private, city, and state cooperation to accelerate the schedule for the improvements to this critical interchange. The city and developer of a large shopping center created a Transportation Development District (TDD) to fund the city’s share of the improvements. The State of Missouri acquired Economic Development Funds for their portion of the project and administered the design contract and bidding. This project included coordination with numerous cities, including Kansas City and Raytown.
The existing interchange is a standard cloverleaf within 1.5 miles of four diamond interchanges. With this tight spacing, there are numerous weaving overlaps, as vehicles try to enter and exit the highways in the same space. The interchange currently serves over 100,000 vehicles per day.
CARS Program, Prairie Village, Kansas
In past years, Affinis has provided both design and full-time construction observation on CARS programs for Prairie Village. The work involves the rehabilitation of collector and arterial streets. Our current scope of services is for design.
The methods of rehabilitation include mill and overlay; curb and sidewalk repair; adding sidewalk; ADA ramps; and concrete paving at major intersections. The improvements are constructed with city and CARS funding, which are administered by Johnson County. As with any project, responding to residents is crucial. As part of the Citizen Inquiry Tracking Program, we respond to residents’ complaints and concerns within 48 hours.
Here is an example of a CARS project we did in 2012.
Switzer District Athletic Complex, Blue Valley School District
Switzer District Athletic Complex (SwiDAC) is often referred to as the crown jewel of Blue Valley School District (BVSD). The complex is home to four of the Blue Valley High Schools’ football and soccer teams.
The shared facility was showing signs of deterioration with severe erosion in sloped green spaces and along the edge of the concrete bleachers. Affinis engineers prepared a report and construction cost estimates for a variety of solutions to repair eroded slopes and eliminate future erosion. The solutions also addressed needed maintenance to the existing structures. The report helped BVSD budget and allocate funds to construct the recommended solution. The overall construction budget for the SwiDAC improvements was $1.1 million. BVSD retained Affinis to perform the design, prepare construction documents, and assist with construction services.
The design included the addition of 15-foot tall, segmental ‘big block’ walls adjacent to the bleachers to help flatten slopes and eliminate erosion. The walls also helped create an open area that can be used during sporting events for lawn seating. Concrete pads were constructed between the bleachers and track to provide new, portable seating for students. On the upper concourse of the bleachers, ADA accessible patio areas with picnic tables were added to give spectators a place to eat and view the events. New landscaping was placed and irrigated. The improvements included new handrail and fencing as well to secure the complex and provide a safe venue for users.
On-Call Stormwater, Olathe, Kansas
The City of Olathe selected Affinis for a multi-year, on-call stormwater services contract. The anticipated scope of work included surveying, drainage design, design of stormwater management facilities, fluvial geomorphology, dam and spillway structural analysis, geotechnical investigation, and hydraulic and hydrologic analysis. We have completed six task orders as part of our partnership. Common elements of our assignments include topographic surveying, existing system condition assessment, hydraulic and hydrologic modeling and analysis, floodplain mapping, permitting, alternative analysis, and preliminary engineering studies (PESs).
