Addendum No. 3 – Baker Boulevard Over Mojave River Bridge Replacement

This is an addendum to the solicitation documents for the Baker Boulevard Over Mojave River Bridge Replacement project issued by the San Bernardino County Department of Public Works. Addendum No. 3, dated September 15, 2026, modifies the original contract documents and establishes new bid submission requirements. The project involves replacement of an existing timber bridge with a modern reinforced concrete structure, including roadway approach modifications, utilities relocation, and associated infrastructure work. The addendum revises the bid opening date from 10:00 a.m. on Thursday, September 17, 2026, to 11:00 a.m. on Tuesday, September 22, 2026, with bids submitted electronically via the ePro System and publicly viewable through goto.com. The addendum replaces Proposal Pages P-4 through P-8 with revised pages that incorporate additional bid items and clarifications regarding contractor responsibilities. Notably, the addendum addresses utility conduit work requirements, specifying that the contractor is responsible for installing conduits and couplers in the bridge as shown on plans, and includes new bid line items for tubular handrailing. Bidders must sign and submit the Bidder's Certification acknowledging receipt of Addendum No. 3 with their proposal; proposals lacking the executed certification will not be accepted.

The revised proposal pages introduce 126 line items spanning base bid and alternate bid categories, covering demolition, structural work, roadway construction, traffic control, environmental compliance, and electrical work. Key additions include a Supplemental Work at Force Account line item for unforeseen differing site conditions (200,000 FA at $1.00), Time Related Overhead calculated on a daily basis (355 WDAY), and 6-inch, 2-inch, and 4-inch conduit items (Type 1) with quantities of 2,496 LF, 1,407 LF, and 938 LF respectively. The addendum also establishes bid subtotals for the base bid, Add Alternate 1 (Concrete Barrier Type 85SW), and Add Alternate 2 (Alternate Luminaire). All requirements referenced in Addendum No. 3 must be considered along with existing contract documents during bid preparation. The project is federally funded through Caltrans Federal-Aid Project No. 5954(193) and is subject to prevailing wage determinations, Build America Buy America Act requirements, and other federal and state compliance mandates.

2. PROPOSAL PAGES

a. Delete Proposal Pages P-4 through P-8 and replace with Revised Addendum No. 3 Proposal Pages P-4 through P-8 (Attachment #1).

3. DIVISION X – ELECTRICAL WORK

a. On SP-109, add the following after 87-1.03E(3):

Replace “Reserved” in section 87-1.04 with:

Payment for conduits include full compensation for furnishing and installing the conduit, expansion fittings, sweeps, couplings, pull tape, supports, fittings, bonding and grounding components, corrosion protection, and all other incidentals necessary to complete the work as shown on the plans and specified.

Questions and Answers:

Q: Who performs/pays for utility conduit work should be addressed. The General Plan calls out conduits relocated by others. Sheet 83 calls out conduit by contractor. Utility Relocation Plans call out "Customer to install 6" HDG Conduit in Bridge". The specification requires contractor to arrange relocation. There is not a bid item for the conduit work.

A: Contractor is to install conduits and couplers in the bridge as shown on the plan, see Addendum No. 3 for additional bid items related to this work.

Q: Bid item for Tubular Handrailing is missing.
