Supported Cone Roof Installation

Fabricate & Install New Supported Cone Roof

The screening estimates are based upon the following assumptions:

  • Tank is clean, gas and lead free and ready for hot work
  • Good access exists to tank for equipment and materials
  • Doorsheet is a minimum of 8’ high x 8’-6” wide.
  • No hours are included for a dedicated fire/safety watch.
  • Tank does not require jacking and leveling
  • Integrity of old structure and roof plate is good enough to allow demolition
  • All design, fabrication and construction in accordance with the latest edition of API 653 & 650
  • Existing tank shell is within API-650 dimensional tolerances as far as level, plumbness, peaking, banding and buckles.
  • Slope of the existing bottom does not exceed 1” in 10’ (either cone up or cone down).
