The project was in conjunction with the Caltrans/Riverside County <br /> Transportation Commission (RCTC) HOV project on the 91 Freeway. It consisted of installation of <br /> approximately 9,260 linear feet of eight-inch ductile iron pipe,five fire hydrants,eight domestic water services <br /> and other related appurtenances on Vine Street and surrounding streets. This work was completed by Water <br /> Division Field Forces on December 2010. Subsequently, RPU hired Laird Construction thru the Water's <br /> Contractors Panel to pave over the newly constructed pipeline. The paving work was completed in January <br /> 2091. <br /> Due to unexpected challenging field conditions and associated costs including construction management, <br /> inspection, and geotechnicaI testing, the actual cost of pipeline construction was higher than initial estimate <br /> and Board authorized amount. The jack and bore portion of the work took two days longer than anticipated <br /> and a water line originally shown as abandoned on construction plans was in service requiring additional <br /> effort to cut and plug. These changes resulted in additional expenditure of $28,000 of which the <br /> Caltrans/RCTC portion is$9,250. <br /> FISCAL IMPACT: <br /> The capital expenditure for Work Order No. 1024639 which includes all design, construction, paving, and <br /> contract administration is summarized in the following table: <br /> -Description: Approved Budget Project Corn fetion Difference <br /> ❑esi n/Surve /Pothole/CEQA $ 12,000 $ 14,197 $ 2,197 <br /> Construction $192,500 $206,504 $ 14,004 <br /> -Paving $100,000 $ 95,494 $ 4,506 <br /> Contract Admin. $ 10,431 $ 10,131 <br /> -Soil-Paving Testing $ 6,374 $ 6,974 <br /> Total $304,500 $332,800 $�M0s — <br />
