Question

1) why is the difference between an avoidable delay and an unavoidable delay important to a contractor? 2) What is the difference between a calender day and a working day? 3) Why would it be necessary and desirable to perform resource leveling for a construction schedule? 4) In which parts of a schedule should a contractor share the most detail with an owner? 5) As a contractor, what concern would you have regard cost and productivity if an owner directed you to use overtime to catch up on a scehdule?

Answer 1

1. Difference between avoidable and unavoidable delay is important to contractors as the construction management always works in the direction of minimzing the time taken by the activities and hence to reduce the overall completion time of the project so an avoidable delay lags the activity uncertainty.

2. Calendar days are the all normal going 365 days divided into 12 months as per the calender whereas working days are the days in a week/month/year a person is on duty with any organization etc.

3. When performing project planning activities, the manager will attempt to schedule certain tasks simultaneously. When more resources such as machines or people are needed than are available, or perhaps a specific person is needed in both tasks, the tasks will have to be rescheduled concurrently or even sequentially to manage the constraint. Project planning resource leveling is the process of resolving these conflicts. So it makes the balance between the pace of completion of activities and the resources available.

4. Under the pre planning and resource and time of completion estimation schedule.

5. If contractor use overtime to catchup on a schedule the resources required will increase exponentially and the cost saving strategy of the contractor will tend to fail and the project will cost higher and reduced productivity.

As productivity is the optimum balance of time and cost.
