Term Project for UNLV Civil 3D class Spring 2009.You have been hired to design a 4 ac subdivision. Your client wants 9 lots on the property. You must provide a 60’ public street giving access from Gubler Ave with 5 ft sidewalks on both sides. You will provide a grading plan and a plan and profile of the site when you are finished.Design Constraints-Min Lot Size is 17,000 ft2-Min Frontage 50 ft- Max slope for street is 6%- Min slope for street is 0.5%- Max Grade Change without Vertical Curve 1% in 100ft- Vertical Curve from AASHTO Curve Tables- Max Slope for grading is 2:1- Finish Floor Pad to be 1.5’ above the crown of the street.- Dead End street require a Cul-de-sac- Knuckles may be requiredTasksTask 1: Points1. Download “Survey_Horizontal” and “Survey_Vertical” Drawings2. Open “AutoCAD Civil 3D (Imperial) NCS Extended.dwt”, save as Task 13. X-Reference “Survey_Horizontal” and “Survey_Vertical” Drawings as attachments.4. Bind > Insert “Survey_Vertical” to the drawing. After inserting the drawing explode [X] it once.5. Points>Utilities>Convert Land Desktop Points. Put the points in a new points group called “Existing Points”, uncheck keep layers box.6. Points>Edit Points>Datum. Set Datum to 1300 ft.7. SaveTask 2: Surfaces1. Open “Task 1” drawing and save as “Task 2”2. In Toolspace Prospector tab right click on surfaces>create surface.a. Name- “Existing Surface” b. Style- “Contours 1’ and 5’ (Background)”3. Under the “Surfaces” tree Right Click on Point Groups and add “Existing Points”.4. Click then Right Click on an SRF-FLT breakline>Select Similar. In the Prospector tab under the “Existing Surface” tree right click on breaklines and click add. a. Description-“SRF-FLT”5. On C-TINN-BNDY layer draw a closed polyline [pl] around the site near the edges of the points. Click on the polyline and in the prospector tab under “Existing Surface” tree Right Click on Boundaries and click add.a. Name-Boundaryb. Outerc. Nondestructive6. Freeze the “V-NODE”, “SRF-FLT” and “C-TINN-BNDY” layers.7. Set up Data References a. In the Toolspace window in the Prospector tab set view to “Master View”b. Right Click on Data Shortcuts [] tree>Set Working Folderi. Pick your project folder with all of your drawings in it.c. Right Click on Data Shortcuts[] tree>New Data Shortcut Folderi. Name “Data Shortcuts”ii. Put it in your working folderd. Click OK e. NOTE: These folders may need to be reset as you work on the project.8. Right Click on Data Shortcuts[] tree>Create Data Shortcut, Check “Existing Surface” to create a data shortcut to the surface and click OK.9. SaveTask 3: Drafting1. Open “Survey_Horizontal” drawing and save as “Task 3”.2. Draw proposed right-of-way lines for interior street according to standardsa. Use Clark County (CC) standardsb. Make a rough estimate of how many lots you will need and approximatelywhere the propertylines should be. Leave room for your road to fit in between lots. Straight portions of the road should be 60 wide and cul-de-sacs and knuckles will be a little wider.c. When drawing your road it is always best to determine where your centerline will be first, and then build out.d. Line [L], Circle [C], Polyline [PL], Polyline Edit [PE], Trim [TR], Extend [EX], Fillet [F], Offset [O], Move [M], Copy [CO].e. Label all widths and radiuses using dimensionsf. Put property lines on “PL” Layer and centerlines on “CL” Layer.g. Turn all centerlines, Gubler Ave., Heyer St. and [your name] St., into polylines, Polyline Edit [PE], Join lines also using Join [J].h. SaveTask 4: Parcels1. Open “AutoCAD Civil 3D (Imperial) NCS Extended.dwt”, save as Task 4.2. X-Reference “Task 3” Drawings as attachments, Relative File Path.3. Parcels>Create Parcels by Objects. Press [X] to select from Xref. Select the property lines.a. Create a new site called “Site”b. Parcel Style “Property”c. Area Label Style “Name Square Foot & Acres”d. Add segment Labelsi. Bearing over Distanceii. Delta over Length and Radius4. Parcels>Create Parcels by LayoutYou will usually use the 4th and 5th buttons when creating parcels. Notice you can change the settings using the double arrow key under the red x.5. Be sure all lines and curves are labeled. Put labels that are not legible into a table.6. SaveTask 5: Alignments1. Open “AutoCAD Civil 3D (Imperial) NCS Extended.dwt”, save as Task 5.2. X-Reference “Task 3” Drawings as attachments, Relative File Path.3. Create alignments for Gubler Ave., Heyer St. and [your name] St. (new onsite street). a. Name – “[name] ST.” or “GUBLER AVE” etca. Starting Station – 10+00.00 (Start at the intersection of another street)b. Site – nonec. Style – “Proposed”d. Alignment label set – “Major Minor and Geometry Points”4. Alignment>Create Alignment by layoutOr Alignment>Create an alignment from polylines> in this drawing or in an X-Ref or 5. Create a data shortcut for your new alignments. (see Task 2 for help on data shortcuts)6. SaveTask 6: Profiles1. Open “AutoCAD Civil 3D (Imperial) NCS Extended.dwt”, save as Task 6.2. X-Reference “Task 3” Drawings as attachments, Relative File Path.3. In Prospector tab under Data Shortcut tree, right click and reference the Street Alignments and the Existing Surface.4. Create profiles of Gubler and [name] Street from the following steps5. Profiles>Profile from Surface, Select Algnment and Existing Surfacea. Name - “[name] ST Existing” or “GUBLER AVE Existing”b. Style – “Existing Ground Profile”c. Label Set – None6. Click “Add” then click “Draw in Profile view”a. Name – “[name] ST” or “GUBLER AVE”b. Style – “Profile View”c. Band Set – “EG-FG Elevations and Stations”i. After you create your profiles make the existing surface and the proposed surface Profile 1 and Profile 2 respectively.7. Profiles>Profile from Layout – Create a profile in the profile view showing what you propose for the street. Do this for GUBLER AVE and [name] STa. This profile should follow the existing profile closely, however there is no need for inverts closer than 100 ft apart. Be sure to install vertical curves where necessary. Remember your proposed elevations must match where streets intersect.b. Slopes at intersections are as followsi. Gubler and Heyer 2.0% down to the Westii. Gubler and Palo Verde 0.5% up to the Eastiii. [name] St
