Products such as correspondence lifts, chutes, and pneumatic tube systems, as well as other items specified in this subdivision, may require trained installers. The general contractor might not have any choice as to who will perform the installation or when it will be performed. Long lead times are often required for these products, making early decisions in scheduling necessary.

Many products in Division 14 will require some type of support or blocking for installation not included with the item itself. Examples are supports for tube systems, attachment points for lifts, and footings for hoists or cranes. Be sure to account for these supports.

When estimating any vertical conveying system, make sure all openings for doors, dumbwaiter access panels, etc., are fire-rated per the applicable code. In case of a fire emergency, their shaftways will otherwise act as a conduit for smoke and heat.

Make sure that either the conveying system estimate, the electrical estimate, or mechanical estimate include the tie-in to the rest of the electrical and control systems. This is another item that people often assume someone else has covered.
