CPM SCHEDULES PRESENTATION FOR PRIME CONTRACTORS AND SUBCONTRACTORS
CPM IS. . . . . • DETAIL PLANNING OF ENTIRE PROJECT • SEPARATE FROM JOB-SITE DAY TO DAY SCHDEULING • USED FOR REPORTING AND ANALYZING JOB-SITE SCHEDULING EFFORS • A CONTRACT REQUIREMENT
ORIGINAL CPM. . . . • BEST INITIAL PLAN FOR THE PROJECT • FORCES DETAIL PLANNING AND THOUGHT • ESTABLISHES EARLY WARNING SYSTEM FOR DELAY (MILESTONES) • FULLY SYNCRONIZED TO THE PROJECT • HAS ONE CRITICAL PATH
Initial Input Dos and Don’ts • Do provide information on the forms and in the level of detail required by the contract and Lead Contractor. • Do break the work down into all phases if the project is phased. • Do provide Submit, Approve, and Fab & Deliver activities for all materials and equipment that is not “off the shelf”. • Do provide as a Level 1 minimum, Activity Name, Duration in workdays, and graphic to indicate sequence. • Do provide as Level 2 Man-hour and Cost loading of each activity. • Do ask questions if you need to. • Don’t assume that the Lead Contractor will do this for you. • Don’t subrogate your scheduling privilege to someone else, you may live to regret it. • Don’t ‘pad’ the duration days; you don’t really want to wind up on the Critical Path unless it is true.
Architects and Owners • On Multi-prime state contracts encourage the primes to comply with the Lead Contractors instructions for initial input and updating. Your Lead Contractor is charged with the task. Failure to enforce this may result in paying damages on the project. • Enforce the contract as it relates to each Prime Contractor’s, input, review, signing, and updating. This will work to protect the owner from delay damages. • Negotiate time for change orders when they happen and not at the end of the project.
CPM UPDATING • REQUIRED TO CAUSE CPM TO MIRROR (SYNCRONIZE) TO THE ACTUAL PROJECT • UPDATES RELY UPON ACCURATE INFORMATION • UPDATE INFORMATION COMES FROM FIELD PERSONEL • OFTEN REQUIRES MORE THAN ONE PASS
CPM Updating Dos and Don’ts • Do read the printed instructions on how to prepare for and perform your update. • Do provide the starts and finish dates for completed activities, and start date and remaining duration on started but incomplete activities. • Don’t assume that just because an activity is complete that you do not have to report it’s start and finish date. • Do use the provided form and complete it properly. • Don’t try to provide projected start or finish dates, the software will do that. • Do call and ask for help if you need it. • Do relate all remaining durations to the set data date.
Completed Started but not done !
