BACKGROUND The project consists of the removal and replacement of curb and gutter (to improve stormwater drainage), and the removal and replacement of damaged sidewalks that are potential trip hazards. Pedestrian access ramps that are damaged, missing, or significantly out of compliance with current ADA standards are also included in the project. The proposed concrete work is carefully coordinated to occur before the Annual Street Resurfacing Project scheduled for construction this summer. Street resurfacing, by law, triggers the requirement to address any ADA deficiencies, which this project does in preparation for the street paving work. See Attachment 2 for the general project locations of the planned work. DISCUSSION The Annual Curb and Gutter Replacements for Street Resurfacing Project, CIP No. 23509, consists of removing and replacing approximately 3,200 square feet of sidewalk, 425 linear feet of curb and gutter, 49 new pedestrian ramps (including 7 oversize ramps), and improvements to 38 existing pedestrian ramps to bring them into ADA compliance. Several sections of curb and gutter, sidewalk, as well as several ADA ramps, are impacted by the roots of existing trees. After the concrete is removed in these locations the City's on-call consultant, West Coast Arborists, Inc. (WCA), will be used to assess whether root pruning is feasible or whether the root pruning necessary is so extensive that it would compromise the tree. WCA will present its recommendation to City staff, then perform the pruning or removal as directed by staff. The goal will be to keep the trees, with removal as a last resort. Sometimes removal is unavoidable; for example, when it is determined that the pruning of roots to reinstall the concrete will compromise the stability of the tree. If a tree must be removed, depending on the location, another tree may be planted. During the implementation of the project, and depending on the encountered soil conditions, one of the City's on-call geotechnical firms may be utilized for soil/materials testing to ensure that improvements are constructed on a stable sub-base. Bids Sealed bids for this project were opened on February 28, 2023. A total of nine bids were received, ranging from $495,848 to $979,875, compared with the Engineer's Estimate of $670,255. Attachment 3 is a spreadsheet showing the unit costs and total bid of each bidder. The lowest bid was received from Villalobos & Associates, Inc., of Campbell, California, in the amount of$495,848 which is approximately 35 percent lower than the Engineer's Estimate. Staff had concerns that the low bid is so much lower than the Engineer's Estimate, particularly given that the next four bids are relatively close and compare much more favorably with the Engineer's Estimate. However, staff has discussed the bid with the low bidder who expressed confidence its bid is responsible and that it can perform the project for its bid amount. All other bid documents were found to be in order and past work performed by Villalobos & Associates, Inc., was verified to be satisfactory. Staff recommends award of the construction contract to Villalobos & Associates, Inc. Page 2of3
