3. Session Outline (only 90 Min ;-) • 1:00pm - Introduction • 1:10pm – Project Setup Review • 1:20pm - Preliminary Grading using Points and Featurelines • 1:30pm - Building the Street Corridor Model • 2:00pm - Creating the 3Line Plan n Profile Sheet • 2:20pm - Bonus Discussion Points • Lot Grading and Earthworks Strategy using Street Models • Importing Pipe Networks • Design Team Workload Distribution • 2:30pm - Information Links and Tools

4. Project Dataset Review • Minimum Requirements • Existing Ground Surface model • Site Alignments representing street centerlines • Road Section details • Optional project level objects include • Curb and Gutter Alignments (Knuckles, Cul-de-sacs, Valley Gutters) • Right of Way Alignments (Knuckles, Cul-de-sacs) • Retention Basin or Storm Water Pond Surfaces • Completed Street Design Surfaces • Pre-Set Standards • Drawing Template (DWT) with Custom Object and Label Styles • Standard Road Section Assemblies Drawing • Standard Plan and Profile Sheet

5. Data Shortcut Model Overview OG Surface Site Earthworks Lot Grading and FG Surface Street B Surface Pond Basins and Surfaces Street A Corridor and Street A Surface FG Centerline Profile and Profile Views Alignments Pipe Networks Plan n Profile Sheet Base Layout

6. Why use a Street Corridor? Lot Grading and FG Surface • A single base model drawing that contains: • Link to Centerline Profile Design • Link to other Street Model surfaces • Workspace for Curb and Gutter designs • Street Corridor vs Site Corridor Model • Smaller drawings • Simplified corridor parameters list • Low Risk of Corruption – “Diversified” portfolio • Isolated editing environment for multiple project team members Street B Surface Street C Surface Street A Corridor and Street A Surface FG Centerline Design Profile (Street A) Profile View Base Showing 3 Line Profiles Curb and Gutter Surface Profiles from Corridor (Street A)

7. 7 Steps to Building the Detailed Street Corridor include: • Street, Crown & Gutter Alignments • Preliminary Point Grading • Crown & Gutter Profiles and Featurelines (Warps) • Baseline and Region Parameters • Corridor Surface • Data Shortcuts • Plan n Profile Referencing and Production
