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 40’ private street giving access from Gubler Ave. You will provide a grading plan and a plan and profile of the site when you are finished.Design Constraints-Min Lot Size is 20,000 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. 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 Radius4. Create the Street per the Clark County USD (with required knuckles and etc.)5. 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
