1. 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

2. 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

3. 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

4. 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)

5. 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

6. BGrade
Graphically move VPI to match Ground Line

7. 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

8. BGrade
Detailed Output along vertical curves, EL, G

9. BGrade
Plot multiple gradelines for comparison

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

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

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

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

28. RPW Bridge Fill Plotting Tool
Comparison between GB and standard headslope.
GB flexible enough to mimic almost any shape
Note : less rock at ends where headslope slope gets flatter
