The number of changes implemented on the project is considered to be standard. There were some adjustments to the project scope, mainly related to civil works to accommodate approximately USD $125 million in Procuring Authority-directed changes, and no extensions of time were granted. The Procuring Authority financed (or partnered with other agencies to finance) these changes implemented to accommodate and improve the expanding roadway network in and around the project. These were considered to be typical changes to a large project developed over several years.

The Procuring Authority set up a major project office that assisted in the process of managing changes (see following sections for more information on the major project office) and to reach resolution among the parties on an expedited schedule that was much faster than typical Procuring Authority scope change approval timeframes for routine projects. The major project office meant that the Procuring Authority had staff dedicated to reacting quickly to change management.
