9.4.1
When the scope of work and responsibilities of the fabricator and the erector are changed from those previously established in the contract documents, an appropriate modification of the contract price shall be made. In computing the contract price adjustment, the fabricator and the erector shall consider the quantity of work that is added or deleted, the modifications in the character of the work, and the timeliness of the change with respect to the status of material ordering, detailing, fabrication, and erection operations.
Commentary
The fabrication and erection of structural steel is a dynamic process. Typically, material is being acquired at the same time that the approval documents are being prepared. Additionally, the fabrication shop will normally fabricate pieces in the order that the structural steel is being shipped and erected.
Items that are revised or placed on hold generally upset these relationships and can be very disruptive to the digital modeling/detailing, fabricating, and erecting processes. The provisions in Sections 3.6, 4.4.2, and 9.3 are intended to minimize these disruptions so as to allow work to continue. Accordingly, it is required in this Code that the reviewer of requests for contract price adjustments recognize this and allow compensation to the fabricator and the erector for these inefficiencies and for the materials that are purchased and the detailing, fabrication, and erection that has been performed, when affected by the change.
9.4.2
Requests for contract price adjustments shall be presented by the fabricator and/or the erector in a timely manner and shall be accompanied by a description of the change that is sufficient to permit evaluation and timely approval by the owner.
9.4.3
Price-per-pound and price-per-item contracts shall provide for additions or deletions to the quantity, type, and character of work that are made prior to the time the contract documents are released for construction. When changes are made that affect the quantity, type, or character of work after the contract documents are released for construction, the contract price shall be equitably adjusted.
