Sec. 973.210  Indian lands bridge management system (BMS).

    In addition to the requirements provided in Sec. 973.204, the BMS 
must meet the following requirements:
    (a) The BIA shall have a nationwide BMS for the federally and 
tribally owned IRR bridges that are funded under the FLHP and required 
to be inventoried and inspected under 23 CFR 650, subpart C, National 
Bridge Inspection Standards (NBIS).
    (b) Where a tribe collects data for the tribe's BMS, the tribe shall 
provide the data to the BIA to be used in the nationwide BMS.
    (c) The nationwide and tribal BMSs may be based on the concepts 
described in the AASHTO's ``Guidelines for Bridge Management Systems.''

    \2\ ``Guidelines for Bridge Management Systems,'' AASHTO, 1993, is 
available for inspection as prescribed at 49 CFR part 7. It is also 
available from the American Association of State Highway and 
Transportation Officials (AASHTO), Publication Order Dept., P.O. Box

---------------------------------------------------------------------------

    (d) A BMS shall be designed to fit the BIA's or tribe's goals, 
policies, criteria, and needs using the following components, as a 
minimum, as a basic framework for a BMS:
    (1) A database and an ongoing program for the collection and 
maintenance of the inventory, inspection, cost, and supplemental data 
needed to support the BMS. The minimum BMS database shall include:
    (i) The inventory data described by the NBIS (23 CFR part 650, 
subpart C);
    (ii) Data characterizing the severity and extent of deterioration of 
bridge components;
    (iii) Data for estimating the cost of improvement actions;
    (iv) Traffic information including volumes and vehicle 
classification (as appropriate); and
    (v) A history of conditions and actions taken on each bridge, 
excluding minor or incidental maintenance.
    (2) A systematic procedure for applying network level analytical 
procedures that are capable of analyzing data for all bridges in the 
inventory or any subset. The minimum analyses shall include:
    (i) A prediction of performance and estimate of the remaining 
service life of structural and other key elements of each bridge, both 
with and without intervening actions; and
    (ii) A recommendation for optimal allocation of limited funds by 
developing a prioritized list of candidate projects over a predefined 
planning horizon (both short and long term).
    (e) The BMS may include the capability to perform an investment 
analysis (as appropriate, considering size of structure, traffic volume, 
and structural condition). The investment analysis may include the 
ability to:
    (1) Identify alternative strategies to improve bridge condition, 
safety and serviceability;
    (2) Estimate the costs of any strategies ranging from maintenance of 
individual elements to full bridge replacement;
    (3) Determine maintenance, repair, and rehabilitation strategies for 
bridge elements using life cycle cost analysis or a comparable 
procedure; and
    (4) Perform short and long term budget forecasting.
    (f) For any bridge in the inventory or subset thereof, BMS reporting 
requirements shall include, but are not limited to, percentage of non-
deficient bridges.
