Hello Abhay,
Nice to see you here. Following is my recommended list to check any schedule:
1- Project Start, Finish and any Contractual Milestone Dates.
2- Project WBS; how it is constructed. For example, there should be separate sections for General Requirements, Engineering (Including Shop Drawings and Materials), Construction, Testing and Handing over.
3- The relationship between the Engineering (Shop drawings approvals / Materials Delivery) and the relevant construction activities.
4- The relationships between the Civil, Finishes, and MEP activities.
5- The Duration of the activities, is it reasonable?
6- The cost loading and cost calculations for the activities.
7- The resource loading and resources calculations for the activities.
8- Total Float for the activities.
9- Open ends and predecessor /successor
10- Used Calendar and project working days / holidays.
11- Run the program on the contractual data date to be sure that all calculations are updated.
So, what could go wrong (common mistakes) :
1- Project Start Data, Finish date, Contractual Milestones does not match the contract.
2- The date of Shop Drawings approval is after the date of starting first relevant activity.
3- The date of materials delivery is after the date of starting first relevant activity.
4- Start the Block Works immediately after the above slab casting without allowing for scaffolding removal duration.
5- Finish the MEP works in the ceiling after the start date of the suspended ceiling.
6- Work on ceiling the floors for the same area at the same time.
7- Start final finishes at early stage of the project.
8- Late start of the testing and commissioning.
9- Having negative or high floats.
10- Budget cost is not matching the contract value cost.
11- Resources chart is not leveled (big variances in the required working hours among weeks/months)
Best Regards,
Hany
