Construction planning

The traditional paradigm for construction planning is based on 10 accepted ground rules. However, inherent in these rules are errors that make the paradigm unusable upon implementation by the construction planners. Although convenient and simple to understand, the accepted ground rules result in plans that are difficult to implement because they do not account for uncertainties. A revised paradigm approach to construction planning is based on four stages: diagnosis, information-gathering, deferring and splitting decisions, and absorbing uncertainty (DIDA). DIDA may be the answer to higher effectiveness and accuracy during implementation due to its inclusion of uncertainty in the planning process. The revised DIDA approach to planning may be more complex and difficult to understand, but it creates plans construction planners feel they can implement. Although academicians find the proposed revision to the accepted paradigm faulty, a survey of construction project planners found it highly usable.
