MGIS CAPSTONE PROPOSAL CROSS-COUNTRY PIPELINE ROUTE SELECTION Mitigating “Costs” for Early Concept Development By: Geoff Price June 22, 2009 Advisor: Dr. Todd Bacastow

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

Problem 3 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%) A ? Where & uch? M w o H B

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

Old Problem, New Solution 5 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.

Route Influences 6 Engineering/Cost Socioeconomic Biophysical

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

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

LCP & Model Builder 9 LEAST COST PATH

Research 14 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.
