Agenda
The municipality of Maple Ridge proposed a re-construction of 240 Street, south of McClure Dr. to 109 Ave. and intersection (240 St & 109 Ave.) with drainage improvements.
Project Information
Input
• Survey Points
• Location information from Google Earth
Proces
s
• Civil 3D software to design Roadways
Output
• Plan and Profile View
• Cross Section View
• Cost of Project

project
Data Collection
Import Survey Data and Create Existing Ground Surface:◦ The First Number is a Point
Number,◦ Second Number has 7
digits indicating Northing Coordinates
◦ Third Number has 6 digits indicating Easting Coordinates
◦ Fourth Number indicates Elevation of that point
◦ Fifth Number indicates Point Description
Survey Points
The PNEZD file format is
separated by commas
Point Management in C3D(Using Description Key Set)
After using Pre-defined Description Key Set
Existing Surface
• Existing surface (Contour)
Break lines provide a more accurate existing surface
Give more precise cut/fill volume calculations to allow for more accurate estimations
Break Lines

An X-ref is an ‘external reference' to another AutoCAD drawing file. One file can reference many other files and display them as if they were one. These are used in larger projects for many reasons:
1. They keep the file sizes down2. They allow many users to work on individual
components of a project3. Every time an X-ref is loaded, it is the most
recent version of the drawing4. X-ref's can be updated, added, or unattached
from the main drawing at any time5. You can X-ref drawings that they themselves X-
ref other drawings (nesting)6. (At the end of Process we will be creating
numbers of XREF and use them for Printout)
X-Reference Files
Horizontal Alignment.Vertical Profile or FG ProfileCross sections
Geometric design of roads
•Curve•Spiral•Tangent
Horizontal Alignment is the first
element in roadway design –
created on the
elevation Zero (0).
Horizontal Alignment (Properties of Components)
Profile(EG & FG Profile)
• Existing Ground Profile is a longitudinal cross section along a horizontal alignment passing through a surface.
• FG Profile is the proposed ground profile – through which vehicle will move.
For this Project, two Assemblies were created:
• ‘Assembly-1’Curb gutter, Side walks & Slopes on both sides
• ‘Assembly 2’Right side – curb & gutter, side walk and slopesLeft side- Shoulder and slopes
Assemblies
Assembly -1
Assembly – 2
Intersections are created in order to provide a smooth turn for all vehicles. We used a 15 m radius to allow trucks to turn safely.
Intersections
A corridor is the roadway 3D model that results from the combination of a horizontal and vertical alignment, a surface, and an assembly.
Corridors
Cross SectionsA cross section is a vertical plane taken right angles to Center line of Roadway showing the various control line showing the various elements that make up the roads.
Quantities Takeoff(Earthwork for Roadway)
Cut Volume: 3,565.60 cum
Fill Volume: 25,289.60 CumNet (Fill) Volume: 21,724.00 Cum
Output-1: Estimated Cost
$6,692,900
Output -2: Plan & Profile View
Output -3: Cross-Sections
Summary
I would like to express my deepest appreciation to all those who provided me the possibility to complete this project. A special gratitude I give to Mr Mahmutjan Nur for teaching C3D Methodology and guiding me through the project. I also like to thank Mr. Ziauddin Mohammed for building the base of Civil 3D by his passionate teaching.
Last but not least, many thanks go to all stuff members of Metro College and my fellow students for their kind feedback and help.
Acknowledgement
After completing the Project, I learn few things to became a successful Civil Designer
Always double check the work Never skip any issue Taking responsibility Prepare in advance
Personal Takeoff:
Thank you!(Questions or Comments)
