  1. DIAGRAM Basic Foundation Design

  2. Basic • Foundation Design • Central Pipe Column

  3. Basic • Foundation Design • Central Pipe Column • Tapered EndThe tip is tapered to ease the installation of the foundation into soil

  4. Basic • Foundation Design • Central Pipe Column • Tapered EndThe tip is tapered to ease the installation of the foundation into soil • FinsTwo – four steel fins are welded on the sides of the pipe

  5. Basic • Foundation Design • Central Pipe Column • Tapered EndThe tip is tapered to ease the installation of the foundation into soil • FinsTwo – four steel fins are welded on the sides of the pipe • Top PlateTo mount a structure to the foundation

  6. DESIGN Determining Factors

  7. DESIGN: Determining Factors • SOIL • Geotechnical Report • Boring Logs/Plans • Blow Counts • Water Table Depth • Soil Type • Soil Resistency/Aggressiveness or Corrosion Loss Rate

  8. DESIGN: Determining Factors • LOAD / FORCE • The maximum load of the structure • Maximum Overturning Moment • Moment of Fatigue • Maximum Horizontal Shear • Maximum Lateral Deflection, Rotation • Others: Maximum Torsional Moment, Up Force, Down Force

  9. DESIGN Developing Custom Designs

  10. DESIGN: Developing Custom Designs • PROPRIETARY DESIGN METHODProprietary software and code • Developed by engineers to consider all of the design’s determining factors • Geotechnical capacity is based on the Broms (1964) method • Structural capacity is based on the latest AASHTO specification

  11. DESIGN: Developing Custom Designs • PROPRIETARY DESIGN METHODProprietary software and code • A separate deflection analysis is provided using COM624 (1993) program • Calculates the required amount of sacrificial steel • Calculates the corrosion loss rate appropriate for the site soil and water conditions

  12. DESIGN: Developing Custom Designs • PROPRIETARY DESIGN METHODDrawings • CAD Drawings • All designs are reviewed and approved by an independent engineering firm

  13. DESIGN: Developing Custom Designs • PROPRIETARY DESIGN METHODCoatings • Our system considers the soil conditions and anticipated life of the foundation to determine if galvanization or any other type of special coating is necessary

  14. FABRICATION Engineering Foundations

  15. FABRICATION: Engineering Foundations • SOLID STEEL FABRICATION • Our foundations are fabricated to AISC specifications from various grades of solid steel • Steel thickness, grade, and pipe diameter are predetermined by our proprietary design method

  16. FABRICATION: Engineering Foundations • FINISHING • If necessary foundations are hot dip galvanized or epoxy coated to exact specifications that are predetermined by our design system

  17. INSTALLATION Method and Process

  18. INSTALLATION: Determining Method • METHOD • Numerous proprietary installation methods utilizing various forms of hydraulic equipment • Our proprietary design method analyzes the soil type, location, and size of the foundation to determine which of our proprietary installation methods will be most effective

  19. INSTALLATION: Determining Method • DELIVERY AND MOBILIZATION • Foundations are delivered to the job site ready to install • Metal Foundations shows up onsite with all necessary equipment and manpower to install the foundations

  20. INSTALLATION: Determining Method • PROCESS • Small hole is drilled • Insert Foundation • Hydraulic insertion using a pre-determined method • Any displaced soil is used for backfill • Attach structure
