Platform Worksheet

Please submit the following worksheet for your platform project. Please note that a sketch or drawing of the platform is required.
  • Geographical Information

    CITY, STATE and NEAREST LARGE CITY are important because location may control code to be used for design.

    Platforms sheltered or inside other structures (INDOORS) will not require wind or snow loads. This answer may be apparent from specifications or drawings, but not so apparent from a telephone request for quote.

    Platforms outdoors and ABOVE GROUND (like on buildings) will have larger gust factors for wind conditions.

    Platforms in OPEN AND FLAT TERRAIN support HIGHER wind loads and LOWER snow loads. Platforms can be designed for worst case, but may be conservative and unnecessarily uneconomical.

    (Extending 1/2 mile or more from site in any Quadrant)
  • Design Conditions and Loads

    Building codes may vary by locality. The IBC (International Building Code) is becoming the standard, however, other applicable building codes may be BOCA, SBC, ANSI (now ASCE-7) or a local (city or state) building code. All design information can be easily obtained except local building code information.

    WIND LOAD is usually given in MPH (miles per hour).

    SEISMIC DESIGN CATEGORY is to be designated. If unknown, design will default to ASCE-7.

    SNOW LOAD is given in PSF (pounds per square foot). Local conditions may govern in mountain regions, the west coast through the Rocky Mountain states and the East coast, North of Massachusetts.

    LIVE LOAD is usually given in PSF (pounds per square foot). Typical design values for platforms are:

    • ACCESS PLATFORM (1-3 people - limited use) — 50 PSF
    • OPERATING PLATFORM (1-3 people - constant) — 75 PSF
    • WORK PLATFORM (men with tools, portable equipment) — 100 PSF

    DEFLECTION CRITERIA is typically:

    • Specified as 1/4" for the grating with 100 PSF LIVE LOAD (NOT necessarily the PLATFORM DESIGN LIVE LOAD)
    • Specified as L/180 to L/360 for structural members (span in inches divided by 180 to 360, respectively)

    CONCENTRATED LOADS are ADDITIONAL TO LIVE LOAD and may be permanent equipment, barrels or drums of chemicals, pallets of materials, boxes, etc. Obtain these LOADS in LBS. and possibly an area over which they act (i.e. pallets 4'x4' weighing 4,000 lbs. ea.)

  • Enter “n/a” if not available.
  • Enter “n/a” if not available.
  • (PSF) Local Conditions May Control
    Enter “n/a” if not available.
  • (PSF) Deflections Criteria
    Enter “n/a” if not available.
  • (Barrels, Pallets, Equipment, Etc.)
    Enter “n/a” if not available.
  • (PSF) Deflections Criteria
    Enter “n/a” if not available.
  • Service and Quoting Requirements

    CORROSIVES AND TEMPERATURE may dictate EXTREN® requirements. EXTREN® SERIES may be specified. STANDARD COLOR or OTHER color is needed. HARDWARE will be bolts for structurals, grating clips and bolts, etc. SPECIFY as necessary.

  • (see Corrosion Guide for reference)
  • (°F for Ambient)

  • Additional Notes and File Attachments

    A SKETCH OR DRAWING OF THE PLATFORM IS REQUIRED. Information to Show: Plan view of platform (Width, Length, Etc.); Height above floor and/or grade; Handrails shown in plans as obstructions/interferences; Location of concentrated loads; Type of grating (if known), Etc.
