If a baseline schedule has been revised several times and cannot be used to monitor the project is it useless?
Leading on from our recent article from the esteemed Dr. Apirath Prateapusanond, Managing Director of Quantum PPP Consulting and Regional Director of Tungsten Capital Thailand, she has set out to answer a key question submitted to her team about extension of time claims.
The question of revisions and the role of a baseline schedule is a good one. The baseline schedule is fundamental to good project management, but it is an ideal in many cases – or, as the name suggests, a ‘baseline’. Here Apirath gives a brief explanation of how to manage that as the project continues:
The baseline schedule, or planning schedule, should not be considered a static document; it will be updated to reflect the changing conditions of the project.
The baseline schedule is an initial planning document that is based on the conditions at the beginning of construction. After that, it must be updated with the actual start date and finish date, and with the percentage completion every week. In addition, durations and sequences of remaining works can also be updated according to the present situation.
For example, materials selected may be unique and therefore take a long time to procure. The contractor should adjust and extend the durations required for procurement of materials, accordingly, including an explanation for the reasons for the schedule update.
Since construction is dynamic, it’s common for many incidents or problems to occur. Therefore, a good schedule should also be dynamic and adjusted to suit the changing conditions throughout the project period.
We suggest that good construction management updates the scheduling documents and adjust them for the remaining works on a weekly basis.
We recommend using the QConZol document management service, introduced to the industry by Dr. Apirath Prateapusanond, Managing Director of Quantum PPP Consulting Co., Ltd. in Thailand. The system should be used by all parties in the construction project, including owners, consultants, design consultants, contractors and manufacturers, in order to reduce costs, increase accuracy, avoid unnecessary construction delays and to maintain a good relationship amongst all parties in the construction project.
