BACKGROUND This annual project consisted of the removal and replacement of 487 linear feet of curb and gutter, removal, and replacement of 3,186 square feet of sidewalk, installation of 49 ADA pedestrian ramps as is required by law when resurfacing a street, and modification of 38 existing ADA pedestrian ramps significantly out of compliance with current standards as is required by law before resurfacing. The project was designed in-house and advertised for a competitive bid. The City Council awarded a contract for $495,848 to the low bidder, Villalobos & Associates, Inc., on March 21, 2023, and authorized the Director of Engineering to approve change orders up to the project contingency amount of $74,377 for additional work deemed necessary during construction. Villalobos & Associates, Inc. began work in May 2023. DISCUSSION Budget Four change orders totaling $60,752, including a balancing change order, were issued during construction. The work modified by change orders included: c Change Order No. 1 involved work at 625 Del Sol Avenue: Removed and disposed of a 10-inch tree and ground the stump for $750. The existing tree root lifted the sidewalk and required removal to replace the sidewalk. City Staff will plant a replacement tree. o Change Order No. 2 involved work at two locations: ■ Touriga Drive and Blanc Court: Removed and replaced drainage inlet grate and set to new grade for $1,000. ■ Del Sol Avenue and Bevilacqua Court: Over-excavated approximately 900 square feet with a minimum of 18 inches below finished grade to address unstable soils for installation of new ADA ramps and concrete valley gutter for $4,000. o Change Order No. 3 involved work at 200 Old Bernal Avenue: Removed and replaced approximately 1,570 square feet of lifted and broken sidewalk, which created potential tripping hazards, for $29,830. c Change Order No. 4 involved removing and replacing 824 square feet of sidewalk and 183 linear feet of curb and gutter at various locations including 4875 Hillcrest Way, 4811 Golden Road, 4823 Golden Road, 4835 Golden Road, 5017 Golden Road, and 1664 Orchard Way, for $25,172. c Balancing Change Order: Added 12 square feet of sod replacement and 10 linear feet of curb and gutter; credits for 14 square feet of sidewalk, 319 square feet of temporary asphalt concrete, and two unmodified ADA ramps (that were removed from the work by staff) totaled $5,534. The total sum of curb and gutter, sidewalk, and sod work outlined in the balancing change order resulted from minor changes to the limits of removal and replacement throughout the project identified as "necessary" in the field compared to the plans. The temporary asphalt concrete was completed as a part of the 2023 Streets Preventative Maintenance Project, CIP No. 23570. Page 2 of 3
