DESIGNDetermining Factors
DESIGN: Determining Factors
SOIL
• Geotechnical Report• Boring Logs/Plans• Blow Counts• Water Table Depth• Soil Type• Soil Resistency/Aggressiveness
or Corrosion Loss Rate
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
DESIGNDeveloping Custom Designs
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
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
DESIGN: Developing Custom Designs
PROPRIETARY DESIGN METHODDrawings
• CAD Drawings• All designs are reviewed and
approved by an independent engineering firm
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
FABRICATIONEngineering Foundations
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
FABRICATION: Engineering Foundations
FINISHING
• If necessary foundations are hot dip galvanized or epoxy coated to exact specifications that are predetermined by our design system
INSTALLATIONMethod and Process
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
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
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
