Agenda Introduction Safety Global Alignment of Survey Systems Proof of Concept Conclusion Quality Policy
Safety Positive Effect of Visual Surveys
Safety cont d
Safety - cont d Enhanced Safety Less Personnel Required on Site Faster Data Capturing than Traditional Measurements More Data Captured Resulting in Less Return Trips Hazardous Environments Accessibility of the Area of Interest Process Conditions Reduced Plant Shutdowns
Global Alignment of Survey Systems General Differences between USA and EU Size Brownfield Projects Projects in USA are Generally Larger PDMS, PDS Graphical Interface vs. Data Centric Solution Dimensional Control Different History in Surveying Methods Geographical Access to Site Locations
Global Alignment of Survey Systems - Cont d Global Alignment Multi Office Projects Coherent Work Processes Sharing Resources Reduced Costs Support
Global Alignment of Survey Systems - Cont d Decision Factors in Global Alignment Lessons Learned Hardware LiDAR vs. Phase Technology Software 2D Applications (AutoCAD, MicroStation) 3D Applications (AutoPLANT, PDMS, PDS) Laser Scan Software
Global Alignment of Survey Systems - Cont d Decision Factors in Global Alignment cont d Surveyors Line of Business Hardware, Software Safety Awareness Work Processes The Work Process Should Always Drive the Technology
Proof of Concept Decision Factors to the Project Measuring Cost and Financial Benefits to the Project Time Schedule Location of the Site Visualization of AS-IS Data with New Design Client, Project Team, Construction Team Technology must Meet Client Requirements Safety
Proof of Concept cont d Cost Estimate Example 1 USA Project Site 600 L x 320 W x 100 H, 400 Tie-ins Traditional Survey 2 Trips to the Facility 10 Days in the Field 10 Jacobs Personnel Estimated $110,000 for Jacobs Personnel (Hours and Expenses) Estimated $25,000 for Additional Survey Services Total Cost $135,000 Visual Survey 1 Trip to the Facility 8 Days in the Field 1 Jacobs Personnel 3 Service Provider Personnel 270 Laser Scan Setups Invoiced Amount $85,000 for Visual Survey Services Estimated $10,000 For Jacobs Personnel (Hours and Expenses) Total Cost $95,000 Savings $40,000
Proof of Concept cont d Cost Estimate Example 2 EU Project Site 300mL x 50mW x 20mH, 30 Tie-ins Traditional Survey 3 Trips to the Facility 20 Days in the Field 2 Jacobs Personnel Estimated 28,000 for Jacobs Personnel (Hours and Expenses) Estimated 2,000 for Additional Survey Services Total Cost 30,000 Visual Survey 1 Trip to the Facility 3 Days in the Field 1 Jacobs Personnel 1 Service Provider Personnel 51 Laser Scan Setups Invoiced Amount 22,000 for Visual Survey Services Estimated 2,000 For Jacobs Personnel (Hours and Expenses) Total Cost 24,000 Savings 6,000
Proof of Concept cont d Decision Factors for the Project Cost Savings 20% - 30% Time Savings 20% - 75% Safety Exposure 65% - 75%
Proof of Concept cont d Project Benefits Design More Data Available Earlier Design Decisions Available Information (Drawings, Data Sheets) Construction Visualization of AS-IS situation and New Design Client Design Involvement
Proof of Concept cont d Statements PM and Client 1. AS-IS appeared not to be As Built (240mm difference on the complete plot), this saved high construction costs since pipe bridges and piping would have to be extended in the field. 2. Any additional information required is readily available in the office and no additional traveling is required 3. Laser scanning is much more complete and accurate than measuring by hand. In complex structures (deformed OSBL rack full of piping and cable trays) the scan can be used as design basis for a complete detailed design and no field measurement is required anymore by the steel fabricator.
Proof of Concept cont d Example 1 Coordinate System Check
Proof of Concept cont d Example 1 Coordinate Deviation
Proof of Concept cont d Example 2 Returning Site Visits
Proof of Concept cont d Example 3 Deformed Structures
Proof of Concept cont d 1. Coordinate offset 18,000 Adjustment Piperack, Piping and Cable Trays Lifting Equipment 2. Additional Traveling 9,000 It was Estimated that 6 Additional Site Visits would have been Required. 3. Design and Construction Benefits 15,000 AS-IS Situation Used for Design Decisions Steel Contractor used Visual Survey Shutdown Benefits 400,000 per day
Conclusion Prevent False Expectations Communicate Purpose of Survey within Project Close Communication between Project team, Surveyor and Client Accurate Definition of Areas to be Surveyed Use the Proper Survey Technology & Surveyor Use the Proper Working Method Use the Proper Hardware & Software
