QUESTIONS AND ANSWERS

August 24, 2026

Subject: Project No. 1007091 Embarcadero West Rail Safety Project – Phase 1 (OVR/Market and Oak)

To: All Prospective Bidders

These questions and answers are provided for the convenience of all bidders. Nothing in this Questions and Answers document modifies the bid or proposal solicitation documents (plans, specifications, RFP, RFQ, etc.) for the above-referenced project. All changes to the bid or proposal solicitation documents (plans, specifications, RFP, RFQ, etc.) for the above-referenced project shall be made through written Addenda.

Question 1: The Grading plans (Sheets GD101-104 & 201-213) do not provide any existing topo information. The only place we have found any is in some of the construction details.

This is not sufficient. Please provide existing topo information for the entire project.

Answer 1: Existing contours are shown as dashed lines but printed very light. Addendum plans darkened the contours and provided existing contour labels.

Question 2: On the demo plans, Sheets D207 & D208 indicate Hazardous materials are present

(Demo Keynote 67). Hazardous materials are not indicated on Sheets D101 or D102.

Is this correct?

Answer 2: Hazardous Material may be present within the limits of the DTSC contaminated site on Port of Oakland property. Contractor should refer to the C7. 1007091_PavementDesign, C6. 1007091_HazMaterial, Project Plans and Project Specifications for details and approximate limits.

Question 3: There are two bid items designated as allowance items (Item 25 – Dewatering, Item

194 – Expedite Landscape Soil Testing Service), however no value is provided. What are the allowance values for these items?

Answer 3: Item 25 allowance could be approximately 0.35% of the project cost, Item 194 could be approximately 0.031% of the project cost.

Question 4: For the purposes of obtaining Rail Road Insurance, please provide the following information for UPRR ML 1, UPRR ML 2, Track 065, Track 100, Track 169 and Track 713:

• Number of Passenger trains per day and speeds for each line

• Number of Freight trains per day and speeds for each line

• Owner of each line

Project No. 1007091 Page 14

Answer 4: Passenger train count and Freight train count information along with track ownership information is available from the Federal Railroad Administration (FRA) here:

https://safetydata.fra.dot.gov/OfficeofSafety/PublicSite/Crossing/Crossing.aspx by downloading the FRA inventory for the crossings by inputting the crossing number. The Crossing number may be obtained using the FRA GIS portal here:

https://experience.arcgis.com/experience/b6c12fd0a4774f38a303e3d034775854/

Question 5: The Roadway Section between and against the Railroad Crossing Panels appears to be a unique plug section but no detail is shown. Please clarify the section to be used at the Railroad Crossing Panels for Roadway.

Answer 5: Railroad crossing panels will be constructed by UPRR. 2ft plug adjacent to panels are the limits of pavement reconstruction UPRR will be responsible for.

Question 6: Under what bid item is the Blended Transition for Curb and Gutter shown on Plan

Page CD105 paid?

Answer 6: Bid Item 62 "Curb Ramp Blended Transition"

Question 7: According to the railroad's safety standard, all contractor personnel must be trained in accordance with all regulatory and Union Pacific safety requirements prior to performing work. Please clarify how long the training session will take.

Answer 7: Contractor advised to contact UPRR for length of training.

Question 8: Confirm all landscape works can be installed in one phase & at the last stage/phase before the project's completion. Otherwise, please advise.

Project No. 1007091 Page 15

Answer 14: 24” depth for mainline pipe, 18” for lateral pipe.

Question 15: Please clarify the method of installation for sleeves located under existing paving or crossing existing streets. Is installation to be performed by open trench with saw cutting or by boring? If open trench with saw-cutting is required, please specify the applicable installation detail and the required backfill materials for bidding purposes.

Answer 15: Irrigation crossings will be backfilled with native material, compaction to 95%. Replace paving with a 1’ HMA Plug if not within a full-depth reconstruction area.

Question 16: Referring to Section 801-7, Measurement and Payment, none of the landscape bid items appear to include the irrigation gate valve and remote control wire. Please clarify which bid item is intended to cover the costs associated with furnishing and installing the irrigation gate valve and remote control wire.

Answer 16: Items are included in bid items 184 and 185.

Question 17: Pursuant to Resolution No. 90814 C.M.S., adopted by the Oakland City Council on

July15, 2025, the Local/Small Local Business Enterprise Program (L/SLBE) requirements donot apply to pedestrian right-of-way construction, including construction of curb ramps, sidewalks, curbs and gutters, and other ancillary work necessary for pedestrian right-of-way construction. Please clarify which bid items on the bid schedule apply to Resolution No. 90814, No. 90996, and No. 90996 C.M.S? On past projects, the City has marked the bid form with "x" for bid items related to ROW construction.

Answer 17: City will not mark items as exempt on the bid schedule as the overall L/SLBE requirement for this project was determined through an analysis factoring in the exemptions.

Question 18: Is it acceptable for contractors to list certified SLBE vendors or subcontractors for a scope of work unrelated to the NAICS code under which they are certified and still obtain L/SLBE participation credit? For example, a contractor lists a (Construction Supply Vendor) to purchase electrical materials through, to meet SLBE project requirements. The Construction Supply Vendor is a "Building materials dealer (NAICS code 444190)" and "Other construction material merchant wholesaler (NAICS code 423390)", not an electrical distributor, apparatus, equipment, wiring supplies and related equipment merchant wholesaler (NAICS code 423610). Since the Construction Supply Vendor is not a certified SLBE listed electrical distributor per NAICS code, is it acceptable for contractors to use them or any other non-electrical supplier as a "pass-through" solely to purchase electrical materials to meet L/SLBE project requirements?

Answer 18: L/SLBE credit only applies when the certified firm performs a commercially useful function in the NAICS code it’s certified in. Using a firm as a pass through wouldn’t qualify for L/SLBE credit.

Question 19: Please confirm that the City will provide and pay for all required compaction testing and concrete cylinders? The contractor will only need to coordinate with the owner supplied consultant.

Answer 19: Contractor will coordinate with Construction Management team. Testing and concrete strength requirements are outlined in the contract documents.

Question 20: Will the City hire a 3rd party CM to manage this contract? Or will City staff manage the project as they have done in the past? If the City plans to hire a CM, please provide the name of the CM firm.

Project No. 1007091 Page 16

Answer 20: The City intends to hire a 3rd party CM to support the City in managing the contract. A firm has not yet been selected at this time.

Question 21: Section 2-9.5 of the Special Provisions states, “The Contractor shall survey all storm and sewer structures within the project limits…” and that this work is to be paid under a bid item per Each. There is no bid item included in the bid schedule for this work.

Does this need to be completed, and if so, will a bid item be added to compensate contractor for this work?

Answer 21: Specification Section removed. Storm and Sewer manhole survey is not a contract bid item.

Question 22: Section 5-11 explicitly states that water valve boxes and covers are to be supplied by

EBMUD at no cost. Section 5-10 states that water meter boxes are also to be supplied by EBMUD, but it is unclear if those are at no cost as well. Please clarify.

Answer 22: For Section 5-10: All water meter work on this project, whether new or relocated, will be performed by EBMUD, including furnishing and installing meter boxes and covers.

This work is at no cost to the Contractor. The Contractor shall provide access and keep meter locations clear in advance of EBMUD's work.

Question 23: Bid Item 20 is to Relocate an Unidentified Utility. Spec section 5-15 provides very minimal information except that is to have 12” vertical separation from the storm drain. Not knowing what this utility is and what materials and work are going to be needed (shoring, bypass systems, dewatering, etc), should this item be an allowance with a value determined by the City for bid purposes?

Answer 23: Bid Item 20 refers to an existing telecommunications security line owned by the Port of Oakland and shall be bid as a telecommunications facility. The contractor will be required to execute an NDA with the Port of Oakland prior to performing work on this facility. Costs for obtaining the NDA and complying with any Port coordination shall be included in the price paid for Bid Item 20.

Question 24: Will City of Oakland permits be issued to contractor at no cost? If not what are the anticipated costs for City of Oakland Permits?

Answer 24: Contractor will need to pull no-fee permits from City of Oakland Department of

Transportation permit counter for the work. However, permits issued by agencies and entities other than the City of Oakland will be the responsibility of the contractor.

Permit fees should be included in mobilization costs.

Question 25: Will Port of Oakland permits be issued to contractor at no cost? If not, what are the anticipated costs or will the City reimburse contractor for cost of permits via change order?

Answer 25: Permit fees should be included in mobilization costs.

Question 26: Spec section 203-3.1.2 States that Crack Seal shall be paid by the Lump Sum. Please confirm that there is no crack seal to be completed on the project.

Answer 26: Specification Section removed. No Crack Seal is identified in the project plans.

Question 27: Spec Section 207-3 calls for Lined RCP. There is none called out on the plans nor shown in the details. Is the RCP required to be lined?

Answer 27: Specification Section removed. No Lined RCP is identified in the project plans.

Project No. 1007091 Page 17

Question 28: Demo plans indicate several areas as, “Remove Train Track Panel Area (By UPRR).”

Spec section 300-2.9 for Roadway Ex says rail, ties, other track materials (OTM) are included. Please confirm that all demo of UPRR Panels, track, ties and OTM are to be completed by others and are not included in Roadway Ex.

Answer 28: Existing track material will be removed by UPRR as indicated in the plans.

Question 29: Spec Section 301-2 – Untreated Base has two measure and payment sections. The first stating that compensation shall be paid for “other bid items of work involved, and no other compensation will be allowed thereof.” The second states that, “The price paid per cubic yard of crushed aggregate base shall included…” Assume this means base under concrete improvements is to be paid in associated items and by the cubic yard for base under the asphalt roadway. Please clarify.

Answer 29: Untreated base under concrete work shall be paid for by that bid item and no further compensation will be allowed. Untreated base under roadway sections of hot mix asphalt will be paid by CY.

Question 30: Spec Section 303-5.1.1.6m regarding Parking Kiosk Pay Stations state, “Contractor shall purchase and deliver to the City Maintenance Service Yard the kiosk pay stations as shown on the plans.” Please confirm that this is not to a part of the Project.

Answer 30: Specification Section removed. City to provide Parking Kiosk and installation.

Question 31: Spec Section 303-5.9e states, “Unclassified Excavation for Concrete Work shall occur only at locations shown on the plans or where the Engineer determines the sub-base material to be unstable. Unclassified Excavation shall be measured for payment by the cubic yard.” There is no Unclassified Excavation bid item. Will this work be paid as Roadway Excavation, or will the City be adding a unclassified excavation item?

Answer 31: No unclassified excavation is identified on the plans. All excavation associated with construction will be paid by roadway excavation and roadway excavation (hazardous materials).

Question 32: Will the City consider postponing the bid date and extending the pre-bid question period?

Answer 32: The City does not intend to postpone the bid date or extend the pre-bid question period due to funding deadlines.

Question 33: Section 5-6.3 states that the contractor is to pay the charges for water meter relocation. What are the charges, how many are to be relocated, and which bid item is this work paid under?

Answer 33: Water meter relocations are performed by EBMUD. Per Sections 5-6.3 and 5-14, the Contractor makes arrangements with EBMUD and pays EBMUD's relocation charges directly. Section 5-14 has been revised by addendum to include the EBMUD water meter charge table and to identify the quantity of meters to be relocated. Locations are shown on the utility plan sheets. Full compensation for the EBMUD relocation charges is included in the contract unit price paid for Reconstruct Water Connection (Service). No separate payment will be made.

Question 34: Sections 5-6.5,5-6.6,5-6.7,5-6.9,5-6.10,5-6.11 all outline required days of notice to be provided to the corresponding utility owners to schedule their adjustment work.

Specs state that the contractor is only allowed 5 days from start of concrete demo to

Project No. 1007091 Page 18 pour back per location. How many days (of these 5 days) will be required for the utility owners to perform their adjustment work?

Answer 34: The notice periods identified in Sections 5-6.5, 5-6.6, 5-6.7, 5-6.9, 5-6.10, and 5-6.11 are advance scheduling notification requirements to the respective utility owner. They are not durations of on-site work and are not counted against the 5 day limitation between concrete demolition and pour back. Addendum No. 1 revises Section 5-6.1 to identify the on-site duration the Contractor shall allow for utility owner adjustment and relocation work at each affected location, and to clarify that the 5 day pour back limitation does not apply at locations where utility owner work is required.

Question 35: Section 6-1.12 references no base repair or paving work during school days within two blocks of the following schools. No schools are listed. Please confirm that there are no schools within the project limits that will require this weekend or holiday work.

Answer 41: Confirmed galvanized.

Question 42: Please confirm that leakage testing, pipeline cleaning, and CCTV acceptance will only be required for the new work being installed in BI#74 &75, and NOT any of the adjoining existing storm system.

Answer 42: For installed work only.

Question 43: For BI#24 – railroad flagging, please change this to an allowance item. Since the City is reimbursing the Contractor for the actual cost of said flagging, a lump sum bid amount is not appropriate for this work.

Answer 43: Contractors shall determine lump sum costs of UPRR railroad flagging based on contractor schedule, work to be performed with in 25 ft of active rail, and contractor

Project No. 1007091 Page 19 means and methods. Progress payments to Lump sum item will be approved based on rail flagging invoicing submitted by the contractors on a monthly basis up to lump sum amount.
