DESALINATION

If the project scope borderline is not sealed tight during the bidding phase, the scope creep is unavoidable and natural. The most frequent causes of the scope creep are poorly defined documentation scope and technical queries for additional information from the contractor.
They may double the planned engineering work-hours especially in CI&E.
Despite being aware of this problem criticality, practically all the EPC contractors engaged in the desalination and water treatment projects have no effective mechanism for the scope change control.
Growing share in the EPC contractor’s portfolio of the EPS contracts (S - supervision) not including the construction phase – major revenue source for contractors – makes this problem even more critical. The EPS project risk failure becomes extremely high when the client is represented by big engineering consultant having very sophisticated systems of the documents processing and control. High costs of plugging into such systems are not taken into account by EPS contractors at the bidding phase.
Current approach to the scope change management is focused on the process of initiating and recording the scope change requests; the scope change detection and quantification are left unattended.
CP shifts the focus to the last two points by enforcing FEED (front-end engineering and design) & Front End Management (FEM) and thus sealing the scope tight before the project awarding. As FEM includes the project schedule, the scope change detection becomes trivial – anything not included in the schedule is the scope creep. Project Schedule analyzing tools allow its easy quantification in terms of time, resources, budget, risk, and rework.
Activity rollback is the process of restoring the project schedule to a previously defined state or status typically to recover from an error. Most common errors relate to typical solutions and pre-packaged equipment pieces having high level of the designer confidence. These errors are mismatch between the subcontractor products or systems, late alignment of the process with the client requirements (language ambiguity, unawareness of the national laws and standards), and late discovery of the better products on the market.
