Bridge Planning Layout Tools Horizontal Alignment Tool BGrade Elevation View Plot Tool Bridge Fill Plot Tool Bridge RPW Plot Tool Bridge Planning – integrate gradeline, elevation view, site plan Tools – computer vs. manual – calculations, drafting – many options, modifications

Horizontal Alignment Tool Horizontal Alignment Tool – generate geo-referenced coordinates for spiral/simple curves between 2 tangents Tangents defined by 3 points – export from Global Mapper Enter R, A, STA? Spiral and Simple curve data are calculated and plotted Export file prepared – Global Mapper

Horizontal Alignment Tool Horizontal Alignment Tool – generate geo-referenced coordinates for spiral/simple curves between 2 tangents Excel plot to confirm inputs Shows key geometry data Note Simple vs. spiral – similar alignment, different length

Horizontal Alignment Tool BF76474 – Smoky River near Grande Cache, Hwy 40 : Possible realignment option – R1500, R2000 spirals R2000 – near upper limit for fit Both difficult stream crossing locations, horrendous gradelines (150m high bridge)

Horizontal Alignment Tool BF76474 – Smoky River near Grande Cache, Hwy 40 : Possible realignment option – R600 (110km/hr), R440 (100 km/hr) spirals – existing is R ~ 400m Tangent set to match existing highway with 15 – 20m shift d/s at bridge R600 doesn’t quite fit, big campground impact R440 fits

BGrade Graphically move VPI to match Ground Line

BGrade Data Screen – red values are inputs, blue are calculated STA, EL can be entered or changed from Plot Note – G, K, Overlap, Bridge (EL, G), Cut/Fill

BGrade Detailed Output along vertical curves, EL, G

BGrade Plot multiple gradelines for comparison

Elevation View Plot Paste in XS, GL data Enter basic opening data and typical rock protection data Try range of STA values

Elevation View Plot Base Elevation View plot is automatically updated. Plots GL, headslopes, and rock.

Elevation View Plot Plot can be stretched to mimic natural scale in Excel. Plot can be zoomed in on in Excel.

Bridge Fill Plotting Tool Data Input Screen – requires georeferencing data + some basic fill data

Bridge Fill Plotting Tool Bridge Fill Plot in XY, fill points intersecting natural ground based on DEM.

Bridge Fill Plotting Tool Bridge Fill Plot in Geographic Projection

Bridge Fill Plotting Tool Multiple Bridge Fill Vectors imported into Global Mapper and superimposed on DEM

Bridge Fill Plotting Tool Zoomed In View.
