3 Topsoil, Asphalt, SubCut—One Road with Overlapping Corridors as the Answer? CI3123
Common rural highway design requires the designer to take into account not just the placement of the new road but also all that must be removed, including topsoils, asphalt structures, SubCut (muck), etc. How can we do this? With more than one corridor! Let us think outside the box and see what we can accomplish with multiple corridors overlapping and all working together to get your complex job done. We will calculate removals and placements all at one time using multiple corridors, multiple surfaces, and multiple sample line groups. We will discuss how to account for existing Topsoil, SubCut and proposed Topsoil placement.

4 What are we going to cover today?! Learning Objectives:
Describe SubCut, scarify, topsoil removal and topsoil placement. Create multiple overlapping corridors to show your existing conditions within one section view. We will describe why multiple datum surfaces are required and why they are not possible using a standard corridor. Adjust your Quantity Takeoff Criteria so we can also calculate both removal and placement quantities from these multiple corridors and their multiple surfaces.

6 ADVANCED CLASS This is one of only 5 Advanced Civil 3D classes being offered at AU! So we are going to assume everyone here knows their…….C3D…… You are here because you want to learn something “ADVANCED!”

7 *DISCLAIMER* *The Basics *Intermediates *Advanced
What we will NOT cover in this class! *The Basics *Intermediates What we will cover! *Advanced What we might talk about…. THE “PARADIGM SHIFT” If time permits we will talk about this at the end!

8 What is SubCut? The ugly stuff from 100 years ago located right below your new and very expensive road bed that needs to be removed if you want your road to last for more than 5 years!

9 What is SubCut? (cont’d)
SubCut is the additional material below our Roadbed that needs to be removed to give us more structure stability. SubCut is usually paid for as a separate pay item, since this material can’t be used under the Roadway and must be discarded. There are instances where this SubCut material can be used in ditching and other non-structural fill areas. Sometimes this SubCut material is just scarified and re- compacted by the contractor.

10 Why is this an issue in Civil 3D?
As of today there is no “Magic” calculate “SubCut” button in Civil 3D SubCut requires multiple datum's to be defined within our assembly. This is not possible as of today.

11 What are we trying to solve today?
**QUANTITIES** How much is this going to cost?

12 HOW? 3 - Assemblies 3 - Corridors 3 - Sample Line Groups
Or what I call the 333 plan!

13 Assembly Number one – Existing Conditions
Multiple Assemblies: Assembly Number one – Existing Conditions Subassembly A is the LaneOutsideSuper Subassembly B is the StrippingTopSoil Subassembly C is just a Generic called LinkSlopeToSurface

14 Assembly Number Two – SubCut Condition
Multiple Assemblies: Assembly Number Two – SubCut Condition Subassembly A is the LaneOutsideSuper Subassembly B is the Generic called LinkSlopeToSurface We will change the codes of the daylight point to “Daylight_SubCut” and links to “SubBase”.

15 Assembly Number Three – No-SubCut Condition
Multiple Assemblies: Assembly Number Three – No-SubCut Condition Subassembly A is the LaneOutsideSuper Subassembly B is the ShoulderExtendAll

16 Assembly Number Three (Cont) – No-SubCut Condition
Multiple Assemblies: Assembly Number Three (Cont) – No-SubCut Condition C and D is the Generic LinkSlopeAndVerticalDeflection E is the Generic subassembly called LinkVertical Note the Coding of all three links.

17 Assembly Number Three (Cont) – No-SubCut Condition
Multiple Assemblies: Assembly Number Three (Cont) – No-SubCut Condition Subassemblies F/G are the Generic LinkWidthAndSlope Subassemblies H/I are the Generic called LinkSlopeToSurface Subassemblies J/K are the Generic called LinkOffsetOnSurface, *these are used to label the ROW and any necessary easements **It needs to be noted that all top Links need to be coded “Top” and bottom Links need to be coded “Datum” and the outer Top Link end pt needs to be coded “Daylight,” while the datum outer end pt is coded “Daylight_Datum”

36 FINAL Earthworks: All quantities in one are now included in one material list:

37 Things to remember! Any surface created in Civil 3D can be sampled by a sample group and used for quantities, not just corridor surfaces! There are times when only one Datum line will not be enough! Corridors are just a tool for creating surfaces! Multiple surfaces, multiple corridors and multiple sample line groups are your tools to get your job done! If you really want to shine use conditional subassemblies where possible!

38 The Paradigm Shift! I was notified about this class last week in June
First week in July we had the SHIFT! Subassembly Composer Tool!

39 The Paradigm Shift! Everything in one assembly, in one corridor, in one sample line group! Topsoil Stripping Asphalt Removal SubCut Removal Topsoil Placement ROW and Easement Labels Shapes for everything above!
