necessary repairs. Mark Thomas has started the 35 percent design and is on schedule to complete the design and cost estimates which will be presented to City Council in late summer 2023, along with cost estimates, and a staff recommendation for how to proceed with the repairs. Consulting Services Material testing was completed on the project in accordance with the City's Quality Assurance Plan. The City's on-call consultant, BSK Associates, was on-site at the request of City staff to collect the hot mix asphalt material for laboratory testing and to test the density of the new layer of asphalt concrete to ensure it was properly compacted. The total cost of these services was $19,669. To prevent damage from construction equipment to the trees adjacent to the streets on which work occurred, tree trimming/pruning was needed. The City's on-call tree service contractor, West Coast Arborists, Inc., provided this service for $15,960. Change Orders The following contract change orders (CCO) resulted in a net increase of$195,616 to the construction contract: 1. Change Order No. 1 for $3,839 was for the installation of a temporary parking lot for the Phase 1 opening of the Bernal Community Farm Master Gardener's lots. Ground asphalt concrete, which was generated from the City's ongoing roadway paving project, was utilized to save costs while the contractor was in the same work area. This work was authorized and paid for under the existing contract with O'Grady Paving. Staff recommends that $3,839 be transferred from the Design Phase 1 of the Bernal Community Farm Project, CIP No. 20772, to the Annual Street Resurfacing and Preventative Maintenance Project, CIP No. 22503, to cover the expenses associated with CIP No. 20772. 2. Change Order No. 2 for $12,304 was for extra work performed for a pavement repair on West Las Positas Boulevard east of Tassajara Creek. Two lanes of traffic in the westbound direction were closed to traffic due to pavement settlement. The settlement repair was in urgent need of fixing and beyond the capability of the City's maintenance crew. 3. Change Order No. 3 for $13,100 was for weekend premium charges to labor and the asphalt plant as requested by the City to perform paving operations on a Saturday. Per the project's specifications, the work on Stoneridge Mall Road, between Stoneridge Drive and Genomics Place, was to be performed Monday through Friday from 6 a.m. to 3 p.m. It was determined at the time of the work that the weekend was the best option to perform paving operations in the area to lessen the impact on traffic and residents. 4. Change Order No. 4 for ($1,247) reflected the adjustment to the material cost of oil for the decrease in the cost based on the Oil Price Index.
