This exchange captures bridge plan details with sufficient information for a contractor to submit a bid and proceed with construction.

The content of this exchange is derived from what is included in the plans for the sample bridge analyzed. Information captured within this exchange includes the following:

The information above must reflect design results, and may or may not also include design parameters such as formulas and patterns used to arrive at the design results. In additional to originating model information, derived information such as quantities and structural results are also included in this exchange, as this information was also included in the originating plans. While such information could be generated by software (in the same way that it could by a human based on the plans), it is included according to the same rationale –convenience, verification, or other requirements.

In addition to originating model information and derived summary information, to assist users in the transition to digital models, it may also be useful to include 2D plan information such that the same format as found in plans may be derived from the underlying information.

The structure of the bid may be defined to reflect varying bid scenarios such as a fixed contract amount, alternates for separate work that may be accepted or rejected independently, combinations of alternates where discounts may be achieved, line items with unit costs provided where the actual quantity may vary within a defined range, line items with quantities provided where the unit costs may vary according to market conditions (e.g. asphalt pricing index), or a combination of all.

Plan information representative of this exchange may be found at the following links for each state DOT agency:
