ACPA Quarter 4 2018

www.acpa.org Quarter 4, 2018 13 Lindsey Street (from 24th Ave. SW to East of Berry Rd.), Norman, OK CONTRACTOR: Sherwood Construction Company OWNER: City of Norman ENGINEERS: Poe & Associates, Inc. and Atkins This important stretch of roadway is lined with res- taurants, businesses and homes, and is also a vital link to the University of Oklahoma. With about 25,000 vehicles (including delivery trucks) using this roadway every day, it’s easy to see why there was a lot of atten- tion on this project. The contractor first established a detour by removing the existing curb, then connecting all the driveways with a 6 in. fiber reinforced concrete pavement on un- treated subbase. To construct the subbase, Sherwood used a modified cement-treated subbase/econocrete subbase, which they developed to allow the use of ready mixed concrete. The contractor moved traffic out to install a new storm sewer system which, at some locations, was an 8 ft. x 7 ft. box that was almost 20 ft. deep to the flowline. The replacement storm sewer extended to two side streets to alleviate flooding in the residential areas north of the corridor. Sherwood then detoured traffic to one side of the grade to construct half the new driveways and the 8 in. jointed plain concrete pavement. The traffic was then moved to the new pavement to allow construction of the other half of the roadway. Slipform paving proved to be challenging. String line was set to get the most productive run of each paving section, typically from intersection to intersection. The contractor would then block out alternating driveways, which were poured by hand. The contractor earned a $400,00 incentive for early completion of the project and now, residents and road- way users have a long-lasting, high quality concrete that will serve this busy corridor for many years to come.

The total cost of the project was $17 million, putting it in South Dakota DOT’s Top 10 by dollar volume for the year. BX Civil & Construction was the prime contractor for the project, which included removing existing pavement, grading, and construction of storm sewer, water main, sanitary sewer, concrete paving (70,000 SY), curb and gutter, and sidewalks. In all, the contractor placed 70,385 SY of concrete with a project length equating to about four lane miles. With nine inter- sections/interchanges, a bridge, and 21 businesses along the route, this six-phase project had many complexities. In addition to the project complexities and accelerated time frame, the project team was also mindful of potential impacts beyond the immediate area. The project involved a major interchange on Interstate 29 and could have made vehicle and pedestrian travel difficult to and from South Dakota State University (SDSU), the state’s largest campus. BX collaborated with SDSU leadership to keep traffic flowing in and around the construction area during peak events. BX-CC was able to successfully complete the project and collect incentives of $411,000, and after the project was com- pleted, the BX-CC employees, subcontractors, and project owners celebrated with a catered barbecue.
