TABLE OF CONTENTS Hewlett Packard HP41 CV computation provides an estimate of the weekly expense of a "manpower spread" for pipeline construction in a given year
R. D. Green, Energy Center Fellow, University of Pennsylvania
Pipeline construction payroll expenses can be estimated in a rule of thumb computation that indexes 1982 survey data to any year of interest when an inflation figure is provided (software is provided in the appendix, p. 591).
An estimate of the weekly payroll expense of a "manpower spread" for pipeline construction in a given year is obtained as follows (Tabel 1):
where: P j = Number of employees in category j
E j = Compensation expense per employee in category j
i = Rate of inflation
y = Year for the construction estimate
The present value (PV) of a stream of payroll expenses is found as follows:
| Category *(j) | Position | Weekly compensation **(E j) |
|---|---|---|
| I | Welding crew foreman | 1,750 |
| II | Welding crew welders | 1,670 |
| Pipe crew foreman | ||
| Pipe crew stringer bead welder | ||
| Pipe crew hot pass welders | ||
| Tie in welders | ||
| III | Field office & overhead heavy duty mechanics | 1,250 |
| IV | Bending foreman | 1,200 |
| Bending engineer | ||
| V | Field office & overhead fuel truck driver | 1,175 |
| Field office & overhead grease truck driver | ||
| VI | R.O.W. & fencing dozer operator | 1,125 |
| R.O.W. grading foreman | ||
| R.O.W. grading dozer operators | ||
| Ditching (earth) foreman |
