LEVEL I - schedules

Carmen,
at the FEED Stage build the EPC Schedule around the critical path items (unless Project is Shutdown related).
This is generally the major equipment definition, purcahse order, delivery, installation, commission.

Critical path could be
FEED Study (FEL 2) say 6 months, then say 2 months to decide to go for a FEL 3 which means PO for Major Items say 3 months into FEL 3, say 30 months delivery, 9 months to install and 6 months to commission.

If this doesn’t give the right end date then invite ideas around early long lead orders etc.

Don’t forget to do a planning session so that project team buys in to the schedule and a schedule risk analysis intercativ ewith th estimate.

PETER,

Thanks for your answer.

I BUILT my schedule based on critical LLI. The worst case was 14 months delivery after placing PO. Based on actual information of LLI delivery, I built the construction schedule starting with Equipment setting which was attached to delivery with FF relation + lag.

Fully agree with YOU with regard to cross check the schedule with Estimating. Getting the preliminary Direct Field manhours and with total construction duration, I can have a rough IDEA about how the MANPOWER should be.
