The importance of pre-project planning in the construction industry and its potential impact on project success has long been acknowledged by industry experts. Most experienced contributors in the project lifecycle understand the importance of early planning pre-project planning particularly in Hospital projects which involves lot of critical services during execution the planning plays a crucial role in sequencing and interlinking of the activities. Inadequate planning results in lot of reworking and since there are lot of services involved in hospital projects any issue during execution in one activity affects the entire set of subsequent activities which ultimately results in cost escalation and time delay which is very critical for hospital projects. Data for one hospital project is collected and the PDRI scoring is worked out for key activities. A detailed comparative of estimated and actual quantities and cost is worked out and the comparative for the planned & actual project schedule is also done. The reason for the cost escalation and time delay was analysed. Based on the findings the model which can be used during pre project planning to avoid the cost and time escalation is analysed. Building Information Modelling (BIM) which is dynamic & beneficial tool to be used for such critical projects is studied and the benefits of using this during pre project planning is analysed. Using BIM in pre project planning stage will help in reducing cost and time delay which occurs in projects particularly in hospital projects. This will also help in execution phase of the projects.
