a. Change Mechanism Types

1) Change Directive

a) DEN directed change/scope changes that are necessary for safety or operations – scope addition is not optional. DEN provides a budget via CD, and the contractor responds via CDR with costs (either actual or negotiated). Once the CDR is approved, a change order may be issued for the difference between the CD and the CDR.

2) Change Notice

a) When to use: DEN directed changes/scope for which the contractor can propose costs to do the work. A CN does not mean the work will take place; project impacts, including cost and schedule, must be negotiated and agreed upon before the work takes place. Once the change notice is negotiated, a change order may be issued.

3) Contractor Change Request

a) Adverse or changed conditions encountered by the contractor that were not the result of DEN direction; RFI responses that differ from spec that may result in additional cost or schedule. Once the CCR is approved, a change order may be created.

b. Non-Standard Contract Changes

1) Suspension

a) Suspensions should be recorded through a change notice. The contractor may respond with any associated costs.

2) Termination

a) Terminations should be recorded through a change notice. The contractor may respond with any associated costs.

DESIGN CONTRACT NO. 202265738

3) Minor Contract Language Change

a) Changes to contract language should be recorded through a change notice. In addition to the normal Unifier approval process, Airport Legal Services (ALS) should also review and approve of changes in the contract. Common situations where this may occur:

(1) Project Milestone Changes

(2) Submittal Requirements

(3) Insurance Requirements

(4) Other

(5) Other

4) Specification Change

a) Changes to spec should be recorded through an RFI if possible. If not, then a CN may be issued for spec changes. In addition to the normal Unifier approval process, the spec owner/SME should review and approve of the change.

5) Major Contract Language Change

a) Major Contract Language Changes require the involvement of Airport

Legal Services (ALS) and may require additional approval, up to and including City Council. Situations where this may be necessary would include

(1) Removal of special conditions, exhibits, or attachments to the contract

(2) Increase in contract capacity over a designated value

(3) Any other contract change that has not been covered by this section.

c. Change orders

1) Change Directives, Change Notices and Contractor Change Requests will be executed and incorporated into a contract via a Change order only.
