    Description

    Amendment 0002: Amendment 0002 We had a few questions so we are sharing the answers below. All other terms, conditions, and times remain the same. BIDS ARE DUE JULY 17,2025 AT 2:00CT.

    One question, I noticed the highlighted area regarding delegated design on pdf page 2. Does this mean that minor design details can be delegated to the contractor? The delegated design would be for the pre-fabricated bridges. Those are the only elements that are not ¿designed¿ since they will be built by a manufacturer.



    Can the diaphragms be bolted instead of welded to the girders? Yes they can.



    Does the diaphragm connection bracket need to be on both sides of the diaphragm in addition to each end of the diaphragm? Yes



    Do the bearing plates need to be welded to the girders? Yes they do.



    Do the hardware, girders, bearing plates, diaphragms, nailer angle need to be coated in any way? It would be best if they were to minimize corrosion over time. They can be galvanization (zinc coated), epoxy coated, or powder coated



    Do we need to include the steel angle nailer bracket if so please provide the spacing? The nailers are spaced a maximum of 5¿ oc along the length of the bridge. They can be less than 5¿ to allow for them to be evenly spaced along the length.



    Would these minor design alterations fall within that delegated design? Or should we maintain no deviation from the design we have now? Typically, not. It would be best to maintain no deviation from the plans
