The additional 48 cubic yards of concrete placed was performed by the contractor on a time and material basis , as provided in the standard specifica- tions . In reviewing the estimated quantities for miscellaneous concrete, curb and gutter, sidewalks and handicap ramps, it was determined that the estimated quantities in the Bid Schedule did not accurately reflect the amount of work shown on the plans. The quantity of concrete required for the 460 lineal feet of curb and gutter was estimated per the standard plans , with an 18-inch wide gutter. However, the actual width of the existing gutter on Arrowhead Avenue was 30 inches . The estimated bid calculations for the placement of 20 handicap ramps on Arrowhead Avenue was incorrect, since it appears that the estimate did not include the replacement of the existing concrete apron. Also, there were additional areas of sidewalk that needed to be replaced, that had not been indicated on the plans. This resulted in a total of 138 cubic yards of concrete actually placed in lieu of the 72 cubic yards estimated in the contract documents . The work involved in placing the extra 48 cubic yards was performed on a time and material basis, as provided in Section 4- 103, "changes" in the State of California Standard Specifica- tions. The total estimated project cost included an amount of $106 ,587 for contingencies, which can be used to finance the additional cost for this change order. Federal-Aid Surface Transportation Funds (STP) have been approved to finance approximately 88% of the total project cost, including any required extra work. Caltrans oversees Federal-Aid funded projects to insure compliance with all applicable federal requirements. Their representative has reviewed this extra work, and determined that it is eligible for Federal-Aid funds . Since the contractor is entitled, by terms of the contract, to be compensated for any extra work required in the construction of the project, we recommend that Change Order No. 2 be approved. 1-19-94 5-0264 CONTRACT CHANGE ORDER NO. 2 REV NO.
