The consultant's undertaking preparatory work for phases 1 and 2 were not the same as the construction supervision consultant's for all three phases who were also responsible for preparing Phase 3 subprojects. The construction supervision consultant's thus did not have any responsibility for the design of subprojects under phases 1 and 2. This became an issue after the consultant's that had done the preparatory work for phases 1 and 2 had completed their contract and left Viet Nam. Changed site conditions made it impossible for the contractors to follow the approved design, and so delays occurred. To ensure continuity, only one consultant both for supervision and design should have been selected.
