Revision to Baseline with constraints

Assuming the project has not yet started:

Option #2: Take a copy of the baseline, change the start date as per latest info, and schedule. This will give you new end date.

Option #1:

1) Take a copy of the Option#2 programme, and add a must finish by constraint to then end date(s) as per original contract baseline. Schedule.

2) Filter on total float less than 0. These are all the activities you need to bring forward by adding manhours.

3) Decide which of these activities it would be most efficient to increase manhours on, and do so. reduce the duration accordingly. and schedule the programme.

4) Repeat steps 2 and 3 until you have no activities with total float less than zero.

5) remove the must finish by constraint(s).

6) Add up all the increases in manhours you made under step 3 and report.

Please note sometimes it is impossible to retain the original end dates no matter how many manhours you add. Increased manhours will not reduce durations for procurement delivery or concrete curing, for example. And there are only so many electricians that can work in a single room.

Hi Syed

To take Gary's advice one step further - increase in the daily hours worked creates a drop in production so that anything over 10 hours a day will create at least a 20% production loss.

Longer hours = reduced production.

Dear Mike & Gary thanks for response.

This schedule has 9 areas, progress of each areas roll-up MC of that area. Now due to delay consultant require revised baseline (new baseline) based on new dates this is 7d/w. However, chances are end dates will not be moved so best process should be load more manpower depending on access available? Change the end dates and retain original budgeted manpower.

Agree with Mike but we can load more manpower if client agrees to pay to accelerate the works per new access dates.

I will give try to Gary's suggestion.

More suggestion and approach will be appreciated.

Thanks again.
