3.2 Reasons for escalations 3.2.1 The DPW acknowledged that it faced professional capacity challenges which impacted on how it managed its projects. That notwithstanding, the DPW explained that, once a project has been initiated and changes of scope resulting in escalations are requested by the client department, that department is made aware of the cost implications and has to give the go-ahead to continue with the changes in scope. Feasibility studies were done for each of the three projects. All variation orders were discussed with the DCS. The DPW confirmed that escalation clauses were contained in all contracts exceeding six months, and therefore such clauses were included in all three contracts. The Contract Price Adjustment Provisions (CPAP) allow for contracts to be adjusted in accordance with the Joint Building Contracts Committee's (JBCC) 2000 Principal Building Agreement Edition 4.1 (March 2005).
