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
