  1. MGIS CAPSTONE PROPOSAL Mitigating “Costs” for Early Concept Development CROSS-COUNTRY Pipeline Route Selection Advisor: Dr. Todd Bacastow By: Geoff Price June 22, 2009

  2. Overview • Problem Statement • Old Way, New Way • Route Influences • Least-Cost Path • Model Builder • Inserting Real Cost • Research • Q & A

  3. Problem • Select alignment alternatives for optimal cross-country pipeline construction that meet project requirements. • Summarize alignment alternatives to facilitate real dollar cost estimation for early concept development (+/- 50%) B Where? & A How Much?

  4. Old Problem, Old Solution The Manual Method • Small Scale Paper Maps (USGS, DOE, State Regulatory Dept, etc…) • Hand Delineation • Terrain Evaluation from Aerial Photographs

  5. Old Problem, New Solution The GIS Method • Digital Maps • Spatial Database (retrieval & storage) • Data Manipulation • Data Conversion • Raster Analysis (Map Algebra, LCP, etc.) Used properly, GIS methods are faster, more efficient, more comprehensive, and less expensive than traditional methods.

  6. Route Influences

  7. What is Least-Cost Path? LEAST-COST PATH COST SURFACE LEAST-COST SURFACE (VECTOR) Land Cover LEAST-COST PATH COST SURFACE COST SURFACE LEAST-COST Surface (VECTOR) + = Land Cover Terrain-Slope

  8. Cost-Weighted Surface Influence LEAST-COST/WEIGHTED * .60 = Land Cover + = * .40 = Terrain-Slope

  9. LCP & Model Builder LEAST COST PATH

  10. LCP Results

  11. Cost Estimate Spread Sheet Inserting Dollar Costs GIS Cost Estimating Manual

  12. Cost Estimating Manual GF • Productivity Factors • General Economy • Project Supervision • Labor Conditions • Equipment • Weather • Terrain Factor • Terrain-Slope • Geology Factor • Rock Type

  13. Cost Estimating Manual cont… Summarize Construction Activities

  14. Research • What are pipeline route selection rules of thumb? (i.e., Engineering, Biophysical, & Socioeconomic). • Is there a favorable standard to apply relative “costs” to individual layers? (i.e.., 1,2,3,4 -OR- 1,3,6,9 -OR- other). • Identify a process for determining costs & weights. (i.e., Delphi Method, Analytical Hierarchy Process, etc…) • Identify benchmark candidate(s) for calibrating LCP and inserting real cost. • Using Cost Estimating Manual For Pipelines to quantify labor/equipment estimates and develop a +/-50% cost estimate for route alternatives.

  15. Research Time Line Aug/Sept
