A signigicant logistics and scheduling problem existed for the demolition of these old buildings and the erection of a new one in the middle of an existing plant. Careful construction methods analysis resulted in the innovative solution of using a tower crane to perform the functions needed. A helicopter was used to erect the tower crane as the only feasible method. Total savings by use of this tower crane method over conventional mobile crane methods is estimated to be $100,000 in direct field costs.
