First of all, thanks to all the contributors who have provided their invaulable ideas and experience. My one main concern while deleoping the schedule is the resource loadng. The one piece of information I am falling short is the crew size or crew composition. In general , I consider 4 personnel in a team and all my man power calculation are based on this team size only. This looks like a good assumption for the over all project as such but when I break down the activiites, this assumption is not so accurate. Can you please provide me with the crew size for various activiites. I am working as project planning for EPCm projects so my major works.
