Construction Practices

Most contractors using slipforming do not own their own slipform­ing equipment. A general contractor who finds it feasible to use slipforming has three options:

1. To design, build, and operate the slipform complex. This requires the assistance of expert consultants who will help at every step of the project.

2. To subcontract the work to a subcontractor who special­izes in slipform.

3. To buy or rent the forming system completely designed and fabricated, ready to be erected at the site to be oper­ated by the contractor’s own forces. The cost of renting slipform equipment is based on the linear feet (or meters) of a slide, the capacity and the quality of the equipment. Jacks and jacking rods are used on a rental basis but forms aren’t normally available for rental.
