ABSTRACT:
A method for replacing a defective column that supports a service station canopy involves the use of several cranes. A pair of cranes supports the canopy while the defective column is being removed and the new column is being installed. A second crane assists in lifting the defective column clear of its foundation and in controlling it as it is lowered from its supporting position. The portion of the roof of the canopy surrounding the upper end of the defective column is cut away and a portion of the base of the service station concrete floor surrounding the lower end is removed to allow the defective column to be disconnected from the canopy frame and foundation, respectively. The defective column can then be removed and replaced while the pair of cranes supports the canopy. Once the new column is in place and re-connected to the foundation and frame, the base can be filled with concrete and the roof repaired.
