Presented by Junha Jeon
Civil 3D Roadway Project
-Kanaka Creek, Maple Ridge
British Columbia, CANADA-
Apply NAD83 Coordinate system zone numbers
NAD83 : North American Datum 1983 (Easting/Northing)
WGS84 : World Global System of 1984 (Longitude/Latitude)
In CANADA /USA – NAD83 coordinate system is used.
Type-in :Kanaka creek bc
Zone 10 U
How do we find UTM NAD83 datum zone number for the Project
MTM : Modified Transverse MercatorUTM : Universal Transverse Mercator

[Information] Surface Style : Border Only OK
Only surface border and points with description *DI* (Ditch) will remains.
Create a new layer for break-lines called ‘V-NODE-BRKL’ as per NCS.(NCS stands for National CAD Standards)
Use 2D Object snap (Node), Start to draw 3D Polyline and join DI points.This is the first Break line created in the drawing.
Repeat the procedure to create other break lines for various point groupsone by one.
*di*- ditch, *dw*- drive way, *ep*- edge of pavement, *er*- existing road,*sw*- side walk, *tb*- top of bank, *td*- top of ditch, *to*- slope toes,*walk*- walk way, *wall*- wall
Change scale to 1:200 or 1:250 to see points more clearly.Type REA(REGENALL) in command line after including next break point.

Create Feature Lines
EG Surface included with Feature lines will be more accurate than Break lines to EG surface.A Feature line is a special type of line that grading commands recognize and use as footprint.1

Connect all *gas* points using 2D PL command & Osnap (Node). Use scale 1:500 to see points clearly on drawing.
Repeat to create 2D Polylines for rest of utilities.

Horizontal AlignmentThe Horizontal Alignment is the first DESIGN ELEMENT.
• Horizontal Alignment is the centerline of a roadway passing through certain points in a specific direction and having a certain length
• Transitional Curves (Spirals)- they help in smooth transitioning between a tangent and a curve ( or between a curve and a tangent)
• The elevation of a horizontal alignment is zero (0)
[Components]
• Tangent : fixed length, specific direction, start and end points
• Curve : fixed radius, specific curve length, start and end points
• Spiral : variable radius, fixed length, start and end points
[Horizontal Alignment]
Create Existing Ground Profile
• Existing Ground Profile is a longitudinal cross section along a horizontal alignment passing through a surface (existing ground)
• REQUIREMENTS:• EG Surface• Horizontal alignment passing through the surface
Create Finished Ground Profile• It is the proposed ground profile.• It is the designed vertical alignment created in a vertical plane so as to provide a comfortable ride
along the centerline of a roadway.”• Two Parabolic Curves (no radius - constant rate of change of slope) are in a FG Ground Profile:
• Crest Curve and Sag Curve
Create Kanaka-Assembly-1 : Curb & Gutter, Side walks & Slopes on both sides.
Create Assembly
Right side – Curb & Gutter, Side walk and Slopes Left side- Shoulder and Slopes.
[Kanaka-Assembly-Half-way]
Create Kanaka-Corridor-1 Standard style and Kanaka-Corridor-2(Split Region) for Assembly Half-way.
Create Corridor
• It is a graphical representation of all design elements used in road/highway design
• The previously created assemblies are applied to the corridor in order to obtain accurate cut an fill volumes
• Finally intersections are created also to obtain cut and fill volumes
Create IntersectionIntersections are created in order to provide a smooth transition for all vehicles. We used a minimum of 15 m to allow for trucks.
To get Enough Survey Data – Extend Surface for this Project.
Extend Surface coverage area
Cross Section
Cross sections are the sections created perpendicular to the direction of a roadway. They have to be created at regular intervals on tangents, curves and spirals.
