  1. Use of 3D Visual Technologies for Major Powerplant RehabilitationFebruary 2014

  2. Rehabilitation of 120 MW Powerplant Scope Seismic Retrofit of Building Replacement of three, 40 MW Generating Units Replacement of all Mechanical and Electrical Systems Rehabilitation of Tunnels Regrading Abutment Slope/Road Relocation Intake Gates/Draft Tube Gate Addition Architectural Upgrades and Finishes

  3. 3D Visual Technologies as Design Tools Challenges • Old Facility with Poor Construction Documentation • Confined and Cramped Powerhouse • Operating Powerplant During Construction - Phased Construction 3D Visual Design Aids • 3D Survey • High Definition Survey (Laser Scan) of Powerhouse • TruView – Overlay 3D Point Cloud on Panoramic photo - identify points/ measure distances. • 3D Design • REVIT – 3D Design and Building Information Modeling (BIM) for Powerhouse M&E Design • Navisworks - Clash Detection • Civil 3D • Autodesk 360 – Cloud Rendering

  4. 3D Survey Technologies – HDS Benefits • Precision Measurements (± 6 mm) • Full 3D Point Cloud - All Areas • Measurements at your Fingertips- Fewer Visits to Site • Verification with As Builts - Overlay on Theoretical Model to Identify Discrepancies High Definition Survey (HDS) - Laser Scan Triad Associates (Kirkland, WA) – 4 Man Crew Full Survey - 5 Days 290 Setups - Inside and Outside Cost $130,000 Deliverable- 3D Point Cloud with Leica TruView 3D Model Generation -$80,000

  5. 3D Survey Technologies - HDS Powerhouse Point Cloud Fly-Through

  6. 3D Survey Technologies - HDS TruView –Measuring Tool

  7. 3D Survey Technologies - HDS TRUSS IN REVIT MODEL POINTCLOUD

  8. 3D Survey Technologies – Underwater HDS A Model M210UW UnderwaterLaser Scanner www.newtonlabs.com • Underwater laser scanner technology by Newton Labs captures as-built measurements with sub-millimeter precision, as well as being able to quantify cracks, rust, wear, fissures, corrosion, weld deterioration, pitting and other deformities. • Similar in use to air laser scanners, the Newton Underwater Laser Scanner is tuned for the aquatic environment and produces a dense point cloud easily converted into a CAD model using industry standard software.

  9. 3D Design Technologies Parametric Modeling Entire Project in a single model (Views, Schedules, Sheets, …) Worksharing and Collaboration Minimal inconsistencies in views Fully annotatable, understand real world units Intelligent objects vs. plain line work Consistent, well-coordinated Design Object oriented, no layer management from user side Typical Nuisance CADD Issues are handled automatically Easy visualization, what you see what you get Project data embedded into the model Clash detection Visualization Phased Construction Extract & sort data in a form of database query (such as QTO, schedules, sheet index, …) Job estimated as conventional design 3D Design plus training of 4 staff members - met budget Future benefits – model available for Contractor use / Plant management AUTODESK REVIT (BIM) - 3D Design Tool Features & Capabilities Differences vs. Conventional CAD software Benefits over Conventional Workflow Use of Features to Aid in Project Cost vs. Traditional
