ABSTRACT

The total project duration and anticipated engineering and process design staffing can now be easily approximated.

Given:

From:

Then:

So:

And:

So:

And:

Construction Hours Engineering Hours

Approximate TIC or Equipment count

Construction duration from Fig. 5.1 Peak construction staff

Total duration is 7 + 0.8

Engineering lead time is 9 - 7

But 2 months is less than minimum

Total duration is 7 + 3

Engineering hours used during lead period are 350/0 of 28,000

80,000 28,000

7 months 100 workers

9 months

2 months

10 months

9800 hr

Equivalent to: 9800 + 3 mo. 3300 + 160 hr/rno. 21 x 1.6

Also: Phase 1 hours 28,000 x 0.12

3300 hr/rno. 21 persons avg. 34 persons peak

Assuming:

Then:

5-6 process engineers can be made available

Phase 1 duration approx. 4 months
