Term Project for UNLV Civil 3D class Spring 2008.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 requiredTasks1. Insert the file from the Surveyor into a new drawinga. Convert Land Desktop points to Civil 3D pointsi. Put the points in a new points group called “Existing Points”ii. Set the Benchmark datum for the points to 1300 ft2. Create the Existing Surface from the points and breaklines givena. Name- “Existing Surface”b. Style- “Contours 1’ and 5’ (Background)”c. Breaklines are on the “SRF-FLT” layer,d. Create a logical Surface Boundary around the sitei. Non-destructive outer boundary3. Create the Street per the Clark County USD (with required knuckles and etc.)4. Define the Parcel Boundaries and Subdividea. Create a new site named “Site”i. Site – “Site”ii. Parcel Style - “Property”iii. Parcel Labels – “Name Square Foot & Acres”iv. Add segment Labels1. Bearing over Distance2. Delta over Length and Radiusb. Subdivide the Parceli. Site “Site”ii. Parcel Style “Property”iii. Area Label Style “Name Square Foot & Acres”iv. Add segment Labels1. Bearing over Distance2. Delta over Length and Radius5. Create your street alignments (Gubler and Private)a. Name – “PRIVATE ST.” or “GUBLER AVE”b. Starting Station – 10+00.00 (Start at the intersection of another street)c. Site – noned. Style – “Proposed”e. Alignment label set – “Major Minor and Geometry Points”6. Create Street Profiles (Gubler and Private)a. Profile Viewi. Name – “PRIVATE ST” or “GUBLER AVE”ii. Style – “Profile View”iii. Band Set – “EG-FG Elevations and Stations”1. After you create your profiles make the existing surface and the proposed surface Profile 1 and Profile 2 respectively.b. Profile from Surface – Create a profile of Private Street showing the existing surface.i. Name - “PRIVATE ST Existing” or “GUBLER AVE Existing”ii. Style – “Existing Ground Profile”iii. Label Set - Nonec. Profile from Layout – Create a profile in the profile view showing what you propose for the street. This profile should follow the existing profile closely. Be sure to install vertical curves where necessary.i. Name – “PRIVATE ST Proposed” or “GUBLER AVE Proposed”ii. Style – “Design Profile”iii. Label Set – “Complete Label Set”7. Create a Corridora. Create Assembly i. Name –“Gubler Ave”, “Private St.”, Private St. Cul-de-sac” etc.ii. Assembly Style – “Basic”iii. Code Set Style – “All Codes”iv. Create assemblies for the roads with the following basic criteriaNote: At places like knuckles, cul-de-sacs and intersections other assemblies, profiles and alignments may be needed.b. Create Corridor with its own surfacei. Style – “Basic”ii. Corridor Surface1. Style – “Contours 1’ and 5’ (Design)”2.
