33 >> Presentation Overview Program History Data Collection Reporting Sufficiency Rating 5/26/2016 Bridge Inspection Reports
34 >> Sufficiency Rating Definition: Calculated value used to indicate sufficiency of a bridge to remain in service. Broken down into 4 sections: Structural Adequacy & Safety (55%) Serviceability and Functional Obsolescence (30%) Essentiality for Public Use (15%) Special Reductions (13%) 5/26/2016 Bridge Inspection Reports
35 >> Sufficiency Rating How this affects Funding? Technical Ranking System for HBP Priority Points = (SRF + TBF + LDF + UBF) x 0.5 x BNM x FCM SRF makes up 50 out of 105 possible points Less than 80% = Eligible for Rehabilitation Less than 50% = Eligible for Replacement 5/26/2016 Bridge Inspection Reports
36 >> Sufficiency Rating Values that go into SR Structural Adequacy & Safety Serviceability & Functional Obsolescence Essentiality for Public Use Special Reductions 5/26/2016 Bridge Inspection Reports
37 >> Sufficiency Rating Structural Adequacy & Safety (55%) Superstructure (59) Deductions start at NBI = 5 or less Substructure (60) Deductions start at NBI = 5 or less Culvert (62) - If Applicable Deductions start at NBI = 5 or less Inventory Rating (66) Deductions of loads less than 32.4 tons 5/26/2016 Bridge Inspection Reports
38 >> Sufficiency Rating Serviceability and Functional Obsolescence (30%) # of lanes on and under (28) Average Daily Traffic (29) Approach Roadway Width (32) Bridge Roadway width (51) Vertical Clearance Over (53) Deck Condition (58) Structure Condition (67) Deck Geometry (68) Vertical Under Clearance (69) Waterway (71) Approach Roadway (72) Defense Highway (100) 5/26/2016 Bridge Inspection Reports
