roof. However, installation requires minor structural modifications, as well as modifications to wiring conduit and fire sprinkler piping. Due to budget concerns, each of the new roof access designs were also bid as additive items. Again, because of the lower-than-expected bids, staff's recommendation includes awarding both bid additive items 2 and 3. The library will remain open to the public during construction, excluding a three-week closure period for the replacement of the clerestory windows. Although the contractor is required to schedule activities to limit noise and install barriers to control dust, it should be expected (due to the nature of the work) that there is the potential to impact library patrons' enjoyment of the facility. Activities identified as having the potential to create significant impacts on the public will be completed during the three-week closure or prior to the regular hours of library operations to the degree that is possible. Also, while the library will remain open, at times portions of the interior of the library will be closed to keep the public safe. When an area is closed, the contractor is required to focus work on the area so that it can be reopened as quickly as possible. Outside the library, a fence will be installed around the perimeter of the building to create a working area and a barrier between the public and any potential falling debris. The library front door will have a tunnel (or similar cover) to provide safe access for the public and staff when entering the building. All emergency egress doors will remain available, but all normal library ingress/egress will be through the front door. The specifications allow the contractor to use the vacant lot to the west of the library for construction staging so the library parking lot will remain available to the public. To expedite the project, the contract allows for construction working hours Monday through Friday, 8 a.m. to 7 p.m., and Saturday, 9 a.m. to 5 p.m. Ultimately, it is the contractor's responsibility to manage their workday length and schedule, so it is unknown whether the low bidder intends to use the extended work hours. Engineering staff will work closely with library staff after the schedule is developed by the contractor to limit inconveniences. The project is expected to begin in July and continue through November, although the start of the project is highly dependent on the availability of building materials. Throughout the design process, care was taken to ensure the materials specified were readily available. However, other City projects have suffered schedule impacts due to delays attributed to manufacturing and shipping. Because of this, it is not possible to know the exact time the three-week library closure will occur, but every effort will be made to work with the contractor to track the window materials and provide as much notice as possible. Bids Sealed bids for this project were opened on June 1, 2022. The bid package stated that an award would be made based on the low bid received and that the City reserves the right to also award any or all of the three additive bid items regardless of how it impacts the total project cost (the order of the bids). The table below shows each contractor's base bid; since staff is recommending the award of all three additive bid items, the table also shows the total cost of the project including each bidder's three additive bid item amounts. While it would not have affected the basis of the award even if it did, the table Page 3 of 4
