7 Product Concept AASHTOWare Design and Rating Engines Specifications AASHTOWare Bridge Database (Oracle or SQL Server) ASD LFD 7 LRFR 3D Analysis Analysis 3D Curved Analysis LRFD Line Girder Analysis 3 rd -Party Engine BRASS Import Import Utilities BARS Import BAR7 Import

8 Product Concept Bridge Design and Bridge Rating share much of the same user interface Model data is preserved in the same database Modeling, analysis and reporting processes are independent of each other Design with Bridge Design Load rate with Bridge Rating using the same model 8

9 Design Use Cases Interactive design review and specification checking 9

10 Design Use Cases Preliminary and final design review 10

11 Design Use Cases Comparison validation Enter a bridge once and Compare designs between different engines Compare designs between different versions of the LRFD specifications Compare between 3D and Line Girder analyses 11

12 Rating Use Cases Load rating common bridge types 12

13 Rating Use Cases Support permit routing using the Application Program Interface 3 4 Billerica Bedford Middlesex Turnpike Carlisle North Road Springs Road 225 Carlisle Road Pine Hill Road Old Billerica Road Bedford 62 Street Burlington Road Page Road Concord Road The Great Road 62 Brooksbie Road Shawsheen Road Page Road 62 Hartwell Road South Road Summer Street Grove Street 3 Burlington Mall Burlington 128 Concord Hartwell Avenue Lexington Bedford Road Lincoln

14 Rating Use Cases Load rating based on inspection results 14

15 Rating Use Cases Comparison validation Enter a bridge once and Compare ratings between different engines Compare ratings between different rating methods (ASR, LFR and LRFR) Compare ratings between different versions of the MBE specifications Compare between 3D and girder-line analysis 15
