REQUEST FOR COUNCIL ACTION CITY COUNCIL MEETING DATE: DECEMBER 1, 2015 TITLE: INCREASE SCOPE OF CONTRACT WITH EXCEL PAVING COMPANY FOR RESIDENTIAL STREET REPAIR (PROJECTS 14 -7516 & 15 -7514) (STRATEGIC PLAN NOS. 6, 1B & 1G) C � � CITY MANA R RECOMMENDED ACTION CLERK OF COUNCIL USE ONLY: APPROVED ❑ As Recommended ❑ As Amended ❑ Ordinance on 1" Reading ❑ Ordinance on 2ntl Reading ❑ Implementing Resolution ❑ Set Public Hearing For CONTINUED TO FILE NUMBER Approve an increase of $200,000 to the Excel Paving Company construction contract for the Residential Street Repair Project, Fiscal Years 2013 -2014 and 2014 -2015, to cover additions to the Scope of Work required to mitigate unforeseen conditions in concrete streets. DISCUSSION On May 5, 2015, City Council awarded a contract to Excel Paving Company in the amount of $1,567,511 to construct the Residential Street Repair Project, Fiscal Years 2013 -2014 and 2014- 2015. The Residential Street Repair Program is an ongoing effort to rebuild neighborhoods by identifying high - priority streets using the City's Pavement Management System and scheduling the repairs in the City's Capital Improvement Program (CIP). The roadway pavements identified for repair in the Fiscal Year 2013 -2014 and 2014 -2015 CIPs had deteriorated due to weather, age, and heavy usage (Exhibit 1). The improvements included removal and replacement of failed concrete pavement, asphalt pavement reconstruction, and replacement of damaged concrete curbs, gutters, sidewalks, cross gutters, and curb ramps. Once completed, these project improvements will enhance the ride quality, surface drainage, and appearance of the neighborhoods. During construction of the residential street repairs, several utilities -- including water and natural gas - -were discovered to be too shallow under the concrete streets. While removing the concrete pavement, the shallowest utilities were inadvertently broken, causing the work to stop until the utilities were repaired. In addition, the subgrade on Walnut Street was discovered to be too soft, causing the asphalt pavement to become unstable, which cannot meet the City's quality and durability standards. To minimize the potential for future conflicts with utility mains and other unintended impacts to the pavement, the contractor must change the construction method used for this project, which requires an increase to the Scope of Work. With this additional work, substandard soil conditions under portions of Walnut Street and several other locations in the project area will be restored, ensuring that the project is completed without further interruption. 23A -1
