### Scale Factor in Tower

My company(Consultant) transferred me to a new project a 4 TOWERS consisting of 34 floors andĀ linked in pairs from the top. The piles and shoring system works were carried out by 95%. When reviewing the Control Points of the project, I found that they used the Scale Factor in the implementation.Note that* Dimensions of the building are 100 * 100 meters.* Tolerance is 7 cm in pile.Ā Ā  the question - Is it possible to complete the building with a Scale Factor?- Or any one have another solution?See More

"First of all, you don't need a scale factor in a building stake out because the architectural dimensions are as they are. If they used a gps in coordinating the controls , then a scale factor of 1-0.99 can be used in correcting distances, butā¦"
