pouring new curb and gutter. The negotiated cost for this work is $50 per linear foot, which is about $9 per foot more than the original bid price for curb and gutter removal and replacement. Staff believes this is a reasonable cost considering the additional work involved. This work results in a project cost increase of $26,700. It was also discovered during construction that a catch basin needed to be reconstructed by hand using block and mortar instead of using a prefabricated concrete catch basin as specified in the plans. This was due to the existing elevations and geometry of the storm sewer pipes. This additional work results in an increased project cost of $1,800 ($4,000 for the 48" hand built catch basin minus $2,200 for the prefabricated catch basin that will no longer be paid for through the contract). It is also worth noting that during construction it was discovered that five areas of Sunwood Drive were constructed with less than 2-inches of bituminous pavement. Therefore, approximately 1'/2" of the existing aggregate base was removed in each area and approximately 1'/2" of base bituminous pavement was placed on top of the remaining compacted aggregate base to provide a minimum of 3'/2" of bituminous pavement along these segments of Sunwood Drive. The additional pavement tonnage required to complete this work is proposed to be paid using the existing bituminous pavement pay item, which the contractor approves of. The extra work addressed within Change Order #1 results in a total project cost increase of $28,500, though the total cost of the Change Order equals $30,700. Notification: No notifications are required for this case. Observations/Alternatives: Observations: These additional project costs will not impact the proposed assessments for the three benefiting properties. Alternatives: Alternative #1 — Motion to adopt Resolution #16-09-173 approving Change Order #1 for 2016 Mill and Overlay Improvements; Improvement Project 16-00 Division B. Alternative #2 — Motion to deny adoption of Resolution #16-09-173 at this time. Funding Source: Additional funding associated with Change Order #1, which totals $30,700, is proposed to be paid from the Street Overlay Bonds that were secured for this project in the amount of $300,000. Total project cost, including Change Order #1 and 14% indirect costs covering administrative, engineering, finance and legal fees, is estimated at $232,783.68 which is significantly less than the amount bonded for this project. Recommendation: Staff recommends approving Alternative #1. Action: Motion to adopt Resolution #16-09-173 approving Change Order #1 for 2016 Mill and Overlay Improvements; Improvement Project 16-00 Division B.
