Title
FINAL ACCEPTANCE AND FINAL PAYMENT OF CONTRACT K-1920-5 BY AND BETWEEN THE CITY OF NORMAN, OKLAHOMA, AND RDNJ, L.L.C., D/B/A A-TECH PAVING, FOR THE DAWS-TONHAWA ALLEY DRAINAGE IMPROVEMENT PROJECT.
Body
BACKGROUND: Over the past several years, residents along the alley between Daws Street and Tonhawa Street in the Norman Old Town Addition have experienced flooding and property damage due to stormwater runoff flowing north out of the alley instead of west through the alley (see attached project area map). This portion of the Norman Old Town Addition was part of the original townsite. In 2018, Public Works Stormwater Division began working with Cardinal Engineering to design improvements to the alley to prevent stormwater from leaving the alley and flooding nearby properties. Based on Cardinal’s analysis, in order to adequately address the flooding in this area, it is necessary to regrade and install an inverted crown in this alleyway.
On October 22, 2019, City Council approved Contract K-1920-5 between the City of Norman and RDNJ, LLC “dba” A-Tech Paving for furnishing of all labor and materials for the Daws-Tonhawa Alley Drainage Improvements Project (Org 50599968, Object 46101; project DR0057) for an amount of $69,360.
Construction activities associated with the Daws-Tonhawa Alley Drainage Improvements Project were completed in November 2019.
DISCUSSION: This project was funded in the FYE 2019 Capital Fund. Total project costs for construction activities included demolition of the existing alleyway and installation of a new concrete alleyway. The total actual project cost is $69,212.95.
RECOMMENDATION: Staff recommends acceptance of the Daws-Tonhawa Alley Drainage Improvements Project and authorization of the final payment in the amount of $69,212.95.
