It~~ Mn / () , cl>i OF SAN BERNARlOIo - REQUOT FOR COUNCIL AeJlON STAFF REPORT Plan No. 7106, for construction of the storm drain, directs the installation of 463 lineal feet of 72-inch reinforced concrete pipe, between Citrus Street and Mirada Avenue, and 101 lineal feet of reinforced concrete open channel, from Mirada Avenue, south to the north line of Patton Hospital. Contract Change Order No. One would substitute 72" pipe in lieu of the concrete open channel, from Mirada Avenue, extending south- erly 61 lineal feet, The Contractor would also construct a re- quired transition structure under Mirada Avenue and a headwall at the discharge end of the proposed pipe. Total estimated project cost, based upon the actual low bid price, contains an amount of $39,047.40 for contingencies, The installa- tion of pipe at this time would result in cost savings by elimina- ting the necessity to remove and replace the channel with buried pipe as part of the future Master Storm Drain Plans. Also, the underground pipe would avoid further disruption to adjoining residents. The cost for Change Order No. One is estimated at $15,543.20, for an increase in the contract price from $239,952,60 to $255,495,80. We recommend that Contract Change Order No. One be approved. 6-14-87 75-0264 eject: Plan No. STORM DRAIN BETWEEN CIT~~,STREET AND MIRADA AVENUE ' '. - .~" ".' 7106 o Date: June 16, 1987 Ffle No. 4.425 ,:) ENGINEERING DIVISION DEPARTMENT OF PUBlIC WORKS CITY OF SAN BERNARDINO.
