(a)
- (1) Arkansas Department of Transportation initiated modifications to the DBA after proposal submission should generally be limited to areas which the requirements included in the RFP cannot be easily addressed or known by the design-builder during proposal preparation.
- (2) A situation may occur when the preliminary design, provided by the department in the RFP, conflicts with existing conditions or some other circumstance that is identified during construction, which is at no fault of the design-builder.
- (3) When such a situation occurs during the project, a modification to the DBA should be in order.
- (4) The procedures for authorizing, administering, and executing such modifications should be similar to those required by the department during construction in a DB-B project.
(b)
- (1) Due to the fast-paced nature of D-B projects, increased attention to contract changes is important to maintain the project schedule and mitigate costly delay claims.
- (2) On large-scale or complex projects, the department should consider the establishment of a change review board.
- (3) Although highly project dependent, the frequency of board meetings would be anticipated to occur monthly during the first half of the implementation phase, and then shift to bimonthly or on-call basis thereafter as final design would be complete, many foundation elements would be in place, and the anticipated number of changes due to field discoveries would decrease.
- (4) The board should consist of department personnel with sufficient experience and stature, with experience diverse enough to allow the board to review all facets of the change order and the confidence to reject or approve the change order for the department.
- (c) A common example would be the discovery of additional, previously unknown utilities that must be removed or relocated by the design-builder when the work would be included on the critical path of the design-builder.
- (d) In addition, recommended best practice is to maintain a change log for all changes, tracking them from identification of potential changes/first written notice to their resolution (rejection, withdrawal, or resolution in the form of an executed change order).
