5.5.72 Contractor Hours

2007 SMRP Page 1 of 2 DRAFT Rev 1

Prepared by: Bruce Hawkins Date: February 7, 2007

A. Definition:Contractor Hours is the percentage of contractor labor out of the total quantity of labor used to

maintain assets.

B. Objectives:This metric allows one to determine whether the permanent maintenance workforce is

appropriately sized and staffed for the maintenance workload. Top performers typically use

some complement of contractors for specialty crafts and/or skills, for peak or abnormal

workloads (such as outages/turnarounds/shutdowns) and for the use of specialty tools/resources

(e.g., cranes, vibration measurements, etc.).

C. Formula:Contractor Manpower (%) = Contractor Labor Hours x 100

Total Maintenance Labor Hours

D. Component DefinitionsContractor Labor Hours Hours used by contractors performing

maintenance on the site. Include all hours for

routine service work as well as those used on

outages/shutdowns/turnarounds. Include

contractor hours used for capital expenditures

directly related to end-of-life machinery

replacement (this is necessary so that excessive

replacement vs. proper maintenance is not

masked). Do not include contractor hours used

for capital expenditures for plant expansions or

improvements.

Total Maintenance Labor Hours Total hours includes all in-house maintenance

(including maintenance performed by operators,

e.g., TPM) and contractor labor hours for the

period. Include labor hours for normal operating

times as well as outages/shutdowns/turnarounds.Include labor hours for capital expenditures

directly related to end-of-life machinery

replacement (this is necessary so that excessive

replacement vs. proper maintenance is not

masked). Do not include labor hours used forcapital expenditures for plant expansions or

improvements.

E. Qualification:

1) Time Basis : Monthly, but can be measured weekly or annually as well.2) Indicator type : Lagging3) Useful for developing trends in overall labor usage requirements4) Typically used by corporate managers, plant managers, maintenance managers, human

resources managers, vice presidents to compare different sites.

F. Example Calculation:Following are the categories of maintenance labor used last month at the site:

Plant Maintenance Craft Labor 821 hours

Contractors used for roofing repairs 240 hours

Labor applied to a chiller compressor service contract 13 hours

Contractor used to clean the cooling tower basin 200 hours

Contract thermography scan 16 hours

Total maintenance labor hours used 1290 hours

Contractor labor hours used 469 hours

Contractor Hours = 469 hours = 36.4%

1290 hours
