BACKGROUND The project consists of removal and replacement of curb and gutter (to improve stormwater drainage), and 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 prior to 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. 22509, consists of removing and replacing approximately 3,600 square feet of sidewalk, 1,350 linear feet of curb and gutter, 60 new pedestrian ramps (including 1 oversize ramp), and improvements to 53 existing pedestrian ramps to bring them into ADA compliance. Several sections of curb and gutter, 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 their 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 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 23, 2022. A total of nine bids were received, ranging from $589,502 to $932,880, compared with the Engineer's Estimate of $625,000 (see Attachment 3). The lowest responsible bid was received from Rosas Brothers Construction of Oakland, California, in the amount of $589,502 which is approximately six percent lower than the Engineer's Estimate. All other bid documents were found to be in order and past work performed by Rosas Brothers Construction was verified to be satisfactory. Staff recommends award of the construction contract to Rosas Brothers Construction. Budget A total of $750,000 was budgeted for this work in the Annual Curb and Gutter Replacements for Street Resurfacing Project, CIP No. 22509, in the FY 2021/22 Capital Improvement Program. The anticipated total expenditure for this project is $693,406, Page 2 of 3
