PARKER, CITY MANAGER FROM: DOUGLAS S. STACK, DIRECTOR OF PUBLIC WORKS/CITY ENGINEER SUBJECT: AUTHORIZE A CONTRACT CHANGE ORDER WITH SUKUT CONSTRUCTION, LLC FOR RELATED GRADING AND THE PLACEMENT OF SOIL STOCKPILES (SURCHARGE) FOR THE TWO BRIDGE APPROACHES REQUIRED FOR THE FUTURE TUSTIN RANCH ROAD PEDESTRIAN BRIDGE (CIP NO. 70243) AT MOFFETT DRIVE SUMMARY Staff is recommending that the City Council authorize a contract change order to Sukut Construction, LLC (Sukut), currently constructing the Moffett Drive (CIP No. 70230) and Legacy Road (CIP No. 70231) Extensions, for grading of the eastern pedestrian bridge pad and the soil stockpiles (surcharge) placement for both bridge approaches adjacent to Moffett Drive for the future Tustin Ranch Road Pedestrian Bridge (CIP No. 70243). RECOMMENDATION It is recommended that the City Council: 1. Authorize a contract change order in the amount not to exceed $150,000 with Sukut Construction for the work necessary to complete the eastern pedestrian bridge pad grading and the surcharge stockpiles for both pedestrian bridge approaches based upon bid pricing for similar work under contract and mobilized for the Moffett Drive and Legacy Road extensions; and 2. Appropriate $150,000 utilizing budgeted MCAS Tustin Legacy Backbone Fee Program (Fund 187) funds as programmed in the adopted FY 2018/19 Capital Improvement Program for the Tustin Ranch Road Pedestrian Bridge (CIP No. 70243). FISCAL IMPACT Sufficient funds for this work and design in the amount of $1,400,000 have been budgeted in the FY 2018/19 Capital Improvement Program for the Tustin Ranch Road Pedestrian Bridge (CIP No, 70243) utilizing the MCAS Tustin Backbone Fee Program Fund (Fund 187). CORRELATION TO THE STRATEGIC PLAN The construction of the Tustin Ranch Road Pedestrian Bridge contributes to the fulfillment of the City's Strategic Plan Goal A: Economic and Neighborhood Development. Specifically, the project implementation of Strategy 1, which among other items, is to develop critical phases of Tustin Legacy. DISCUSSION AND BACKGROUND On August 25, 2015 the City of Tustin and Tustin Unified School District (TUSD) entered into a Site Conveyance Agreement for the eventual construction of the Legacy Magnet School. The Authorize Contract Change Order July 3, 2018 Page 2 school is currently anticipated to open in the Fall, 2020. Concept plans are underway to have the Tustin Ranch Road Pedestrian Bridge completed in conjunction with the school opening if so desired. Placing surcharge on the bridge pads will allow settlement of the underlying soils to occur, which is anticipated to take anywhere from six to ten months. This is a similar procedure that was previously used for the Tustin Ranch Road vehicular bridge over Edinger Avenue. On September 20, 2016, Sukut was awarded the construction contract for the mass grade of the school property (CIP 70234) and the surrounding streets and city property including the western pedestrian bridge pad. Pursuant to the requirements of the Site Conveyance Agreement, an as - graded certification and as -graded geotechnical report for the 40 -acre site were transmitted to TUSD on May 1, 2017. On October 18, 2016 the First Amendment to the TUSD Site Conveyance Agreement was entered into by the parties which stipulated among other things that the Moffett Drive and Legacy Road extensions would be constructed including all utility connections and to provide construction access for TUSD by August 31, 2018 or such other time as agreed to by the parties. In response to that amendment, on September 19, 2017 Sukut was awarded the construction of the Moffett Drive (CIP No. 70230) and Legacy Road (CIP No. 70231) Extension Roadway Construction Project which is currently underway. The Moffett Drive work from east of the proposed Legacy Road to Park Avenue is now at a point where utilities have been installed and concrete curb & gutter and asphalt street work are imminent. Prior to these street improvements commencing, monies can be saved by grading the eastern bridge pad and surcharging both pads for the Tustin Ranch Road Pedestrian Bridge now before the streets are further completed. This will also allow ample time for the settlement of these pads to occur prior to actual bridge construction. DouJa- Stack, P.E.
