31 CLARIFICATIONS AS FOLLOWS: Question Answer Pier #4 CIDH has deep cutoff (assumed as part of Frame 1 part of Piles #2 & #3) which is customarily to utilize isolation columns. Why isn't permanent casing specified? Permanent casings are not requied, nor desirable due to potencial scour. Please note the cut-off elevation for Piers 2-4 was revised in Addendum No. 3 Page 6 Book 3, Revised Standards, Section Subcontractor List references the Subcontractor List form. Does this refer to the Bidder s List of Subcontractors form (page 27 of Book 1 Bid Book) or Exhibit 12-B Bidder s List of Subcontractors (page 28 of Book 1 Bid Book)? Addendum #2 will eliminate the Bidder's List of Subcontractors and replace the Exhibit 12-B. Section refers to the revised Exhibit 12-B. Page 6 Book 3, Revised Standards, Section Subcontractor List indicates a new threshold for subcontractors we are to list (only those that will perform work in an amount in excess of ½ of 1 percent of the total bid or $10,000, whichever is greater. Does this apply to both of the forms in #62 above? Addendum #2 will eliminate the Bidder's List of Subcontractors and replace the Exhibit 12-B. Section refers to the revised Exhibit 12-B. Per Page 6 Book 3, Revised Standards, Section Subcontractor List we are to provide subcontractor information such as Public Works Contractor registration number, Percentage of subcontracted work for each bid item listed, etc. Neither of the forms referenced in #62 above provide space for this additional required information. Please specify to which form this information applies, and how we are to incorporate this information into the identified form (or if a new, revised form will be issued by Addendum). Does the city plan to send a revised bid book to planholders based on the changes from Add #1? Section discusses a Prebid Outreach Meeting. Is this another meeting in addition to the Prebid Meeting? If so then please provide details. Addendum #2 will eliminate the Bidder's List of Subcontractors and replace the Exhibit 12-B. Section refers to the revised Exhibit 12-B, which has space for the registration number. No. Bidders should insert the latest bid form that is issued by addendum into the bid book they purchase from the City. Section of the RSS is titled Prebid Outreach Meeting, however it describes the prebid meeting as shown on the Notice to Bidders. No additional meeting is described,nor will be held. 31

32 Please clarify whether this bid is considered Informal or Non-Informal. Ref. Sht. 270 Abutment 1 Elevation, the detail reference B2-8 for the Class 200 Piles is referenced as Alt. X, however, on Sht. 273 Abutment 1 Sect. A-A, the detail is referenced as Alt. Y. Please clarify. Non-informal. Plan sheet 273 has been revised to show Alt "X" and will be included in Addendum #3. Ref. Bid Item 52 Structural Backfill (Bridge) The bid form quantity is 841 cubic yards. However, the sum of the item quantities on Sht. 267 (2nd Street Undercrossing) of 2,405 cy and Sht. 305 (5th Street Bridge) of 690 cy is 3,095 cubic yards. As this is a Final Pay item and not measured, would the Engineer please reconfirm and reconcile the quantity required? The quantities on sheet 267 were transposed. Sht 267 has been corrected and will be included in Addendum 3. Ref. Bid Item 53 Structural Backfill (Retaining Wall) The bid form quantity is 4,048 cubic yards. However, the sum of the item quantities on Sht. 267 (2nd Street Undercrossing) of 250 cy and Sht. 305 (5th Street Bridge) of 1,601 cy is 1,851 cubic yards. As this is a Final Pay item and not measured, would the Engineer please reconfirm and reconcile the quantity required? The quantities on sheet 267 were transposed. Sht 267 has been corrected and will be included in Addendum 3. Ref. Bid Item 48 Structural Excavation (Bridge) The bid form quantity is 7,068 cubic yards. After completing our takeoffs, that quantity seems significantly high. Given the quantity differences noted for Bid Items 52 & 53 and as this is a Final Pay item and not measured, would the Engineer please reconfirm the quantity required? Does the City have any information on the 2 wells that need to be destroyed and the exiting monitoring wells that need to be adjusted? In our search of the provided documents we have not found language that confirms the City of Yuba City will accept generator status of all unknown pre-existing hazardous material and will sign transportation manifests as such in the event that abatement is necessary. Please confirm. Additionally, please confirm that the City of Yuba City will indemnify the Contractor from any loss, cost, expense or fine related to any pre-existing hazardous material. The quantity has been verified and is consistent with non- standard cut slopes required for excavation in the levee prism as shown on sheets 75, 76, 77 and 269. The City does not have as-builts of the wells. The wells must be adjusted to grade per section 76-7 and using materials and construction requirements for new wells per section The City will be considered the generator of the unknown pre-existing hazardous material to the extent the release of the pre-existing hazardous material is not due to the Contractor's negligence or willful misconduct and will sign transportation manifests in the event that abatement is necessary when the City is considered the generator. The City will not indemnify the Contractor from "any loss, cost, expense or fine related to any pre-existing hazardous material." 32

33 No mutual waiver of consequential damages is currently included in the contract. Will the City please revise contract language to include a waiver of consequential damages? Looking at the irrigation specs, can t find them in the specs Type of, vales (Rainbird, or Hunter), irrigation controller (Rainbird etc,) is it 2-wire, type of sprinkler ( 6,4 or 12 pop-ups), make of gate vales brass or schedule 80, and type of flow sensor The City will not revise contract language to include a waiver of consequential damages clause. The irrigation requirements are described on the irrigation plans and specs. Specific brands are not required. Note 1 on plan sheet 118 states that the sewer line is a force main. The specifications only reference bypassing for the CIPP portion of sewer main work. Will a bypass be required for the relocation of the sewer main shown on UD-1? If so, please provide the flow rate of the existing force main. What type of pump/generator redundancy is required for the bypass system? What specifications should we use for the underground systems? Do the Yuba City standards apply throughout the project? The specifications reference City of Yuba City detail TR5 for the manholes. This detail shows 100% CL2AB backfill at a minimum of 5 around each manhole. Will the City accept a smaller excavation to install the manholes? It seems unnecessary to dig a 14 + diameter hole to install a 4 diameter manhole. The quantity for Remove 4 PVC (Water) appears to be incorrect. Sheet UD-8 shows 485 lf of removal compared to the 122 lf shown on the quantity sheet. Please revise the bid quantity. Bid item 106, replace AC surfacing. Is the furnish of the AC included in this item or should the contractor assume it is included in bid item 107 HMA Type A? Please provide Elevations for bottom of Retaining wall slab for all Retaining walls Please provide stages that Retaining walls 35W, 35E, 54N, 54S and 35S are to be constructed as they are not shown in the stage construction details. The force main shown on UD-1 is the lateral from Riverfront Park restrooms. The City will temporarily close the restrooms while system is relocated. Use City of Yuba City standards unless Caltrans standards are shown or specified. The City can accept a smaller excavation on a case by case basis provided the native material and Contractor's means and methods will assure adequate compaction around the manhole. In no case will the City allow an excavation smaller than the minimum necessary to allow adequate mechanical compaction of the Class 2AB backfill. Bid quantity has been revised to a total of 935 LF and will be included on Addendum 3. Item 107 does not include AC to be used for item 106. Item 106 bid amount should include AC necessary for replacement. For retaining walls shown on the bridge plans, the footing elevations are shown on the foundation plans or the retaining wall layout sheets. For the rockery wall, retaining wall No. 59 the slab elevation is based on FG, see details on Sht 380, Wall Details. For retaining wall 231, the footing elevations are on Sheet 382, General Plan. Sheets SC-2 and SC-6 have been revised to include construction of RWs 35W, 35E, 54N, 54S, & 35S. 33

34 Will the City please provide grading details for the ditch running through the basin to be excavated Will the City please provide grading details for the basin to be excavated as no details or topos are shown in this area. I am bidding the demolition phase of the bridge in yuba. There is quite a bit of planning to do given the river and logistics. Please let me know if the bid date is being planned to get pushed. The as builts for the 5th street bridge show 4 Pacific Bell Utility Ducts, these ducts are labeled as transite. Are we to assume they are asbestos? The asbestos report does not address them. The removal of asbestos transite pipe can additional costs and days to the bridge removal. Ditch flowline elevation at the lined channel shown on sheet C-10. Slope of ditch has been added. 6' Graded Ditch detail was revised in Addendum #3. Section D-D on sheet C-10 has been added for clarification in Addendum #3. There are no current plans to push the bid date out. Yes, the transite pipe is expected to contain asbestos. Include provisions for the pipe during bridge removal in your Asbestos Compliance Plan. In addendum No. 3, a note was added to the specs stating that asbestos is present in the pipe. The as-built drawings show that there are (6) 4 diameter Transite pipes concealed in the existing concrete sidewalk that is the entire length of the 5th Street Bridge. Transite piping usually is Asbestos Containing Material. Have these pipes been tested? I did not see the piping referenced in the report, specifications or bid item list. If this piping contains ACM. This is it going to reflect the demolition schedule. Can more time be added for the abatement prior to the bridge demolition? Are there any live cables inside these pipes? Is the abatement of these pipes included in the engineers estimate? The pipes were not tested, but are assumed to contain asbestos. Time alloted is sufficient for asbestos mitgation and demotition. No addditional time will be added. The cables in the pipe are live now, but the utilities will be relocated to the new bridge before the demo. The abatement of the pipes is included in the bid item Asbestos compliance plan. Book 3, Revised Standard Specifications, page 6, Section Subcontract List, identifies the information to be provided on the subcontractor forms. Addendum #2 included two new forms to address subcontracting information Exhibit 12-B Part 1 and Part 2; however, both of these forms also have a column that requests annual gross receipts and age of firm in years. As this is not information generally included in a bid, please confirm that this information will not be required. Please refer to Title 49, Section of the Code of Federal Regulations. This information is required to be collected. However, the City will allow the annual gross receipts and age of firm in years to be submitted with the DBE information after the bids are opened. RE: Bid Item 152 Is this bid item one of the Retaining Walls 1, 2, 3 or 4?... if so, which one?..need to verify quantities. RE: Bid Item 155 Are these a combination of Retaining Walls 1, 2, 3 or 4?... if so, which ones?..need to verify quantities. Item 152 is for the removal of the masonry retaining wall on the levee at Abutment 11. Item 155 is for the removal of the concrete retaining walls No. 1, 2,3 and 4. 34
