The Bridge Project Development Manual : Review processes for bridge plans
Provisional Bridge Layout Verification (PBLR) and permitting is necessary for all bridge designs, regardless of the financing method, before detailed work is carried out. As a rule, the verification shall take two weeks from the date of submission. In the following, the layout is checked: The Field Operations Section of the Design Division checks the layout for street elements, such as
PM of the #VDOTVOSMA Bridge Division logs that the layout has been sent if further issues arise during planning. #STRJTKMTThe Federal Highway Administration (FHWA) demands the verification and acceptance of the provisional bridge design when supervising. JJEPPRUO In the case of a railway, the layout (Railway Exhibition A of the Railway Contract) is sent to the railway operator for verification and permit.
When the bridge is scheduled for Category 6 financing, check that it is suitable for one of the four support programmes mentioned in Section 2 of this book. The Bridge Division projectmanagers check during the concluding Bridge Cost Information (BCI) verification whether all planning and financing questions raised during the initial Bridge Layout verification have been solved so that the bridge can be leased.
When the bridge is not suitable for the promotion class or is not approved by the building authorities, the bridge cannot be rented for building. When there is a structural issue that requires a bridge remodel, the property may need to be withdrawn from the lease if there is insufficient urgency to resolve structural problems.
Prevent the risk to rental data by solving any open questions at the provisional layout check rather than during the PS&E phase.

In the case of railway flyovers or subways, please send the provisional bridge layout to the bridge department and the railway exhibition goods A to the railway safety department (RRD-RSS).

Bridge Division is submitting to FHWA Texas Division for review all provisional designs for all bridgework, key engineering and large water way construction works for which FHWA has overseen them.
Please ask the design department for a complete listing of these products. The FHWA Texas Division and the FHWA Headquarters Office of Bridge Technology have approved provisional documentation for all other bridge construction works, such as the following, for exceptional bridge and structure projects: RRD-RSS's Railway Safety Division is the single point of reference and the main responsible for all issues related to arrangements with railway undertakings.
You will be in charge of the submission of all items required for the implementation of the various kinds of railway arrangements, as well as the drawing of Annex A for work.
