Holloway Consulting is a construction damages and labor productivity expert, and we have examined most popular studies including NECA’s periodic studies.

NATIONAL ELECTRICAL CONTRACTORS

LABOR PRODUCTIVITY

1962 MEMBER SURVEY

The National Electrical Contractors Association (“NECA”) has published several studies on construction labor productivity and overtime. In a 1962 survey, members replied to four questions concerning the effects of overtime on a sporadic, short-duration basis and two questions concerning continuous overtime over several successive weeks. This is an extremely small sample considering that NECA has thousands of members. NECA concluded that the observations were close enough to give substantial confidence in the applicability of BLS values to electrical contracting which provided a more complete coverage.

Notwithstanding NECA’s conclusion, it must be reiterated that on one hand the BLS data were collected under very specific conditions in the manufacturing sector and, on the other hand, NECA data were nothing more than a limited survey, i.e., subjective data which cannot be verified. At best, the coincidental similarity of questionable data can be considered a general indicator.

OVERTIME AND PRODUCTIVITY IN ELECTRICAL CONSTRUCTION, NO. 1

In 1969, NECA published, “Overtime and Productivity in Electrical Construction”, a study conducted by the NECA Southeastern Michigan Chapter. Data are from jobs worked during 1964, but the origin of the data and the work environment are unknown. This study showed a decline of productivity over periods of one to four successive weeks, but failed to address weeks thereafter.  Weeks 2, 3 and 4 simply use multipliers of 1.5. 2.0 and 2.5, respectively, of the first week’s data. This raises some serious concerns with respect to the originality and veracity of the data.

OVERTIME AND PRODUCTIVITY IN ELECTRICAL CONSTRUCTION, NO. 2

In 1989, NECA published a second edition of “Overtime and Productivity in Electrical Construction.” The study provides information on low, average and high productivity loss for 5-, 6-, and 7-day work weeks and 9, 10 and 12 hours per day for sixteen successive work weeks, based on data gathered by NECA since 1969 for journeymen electricians. The origin of the data and the nature of the work environment are unknown.

CLOSING

Perhaps NECA prepared these construction labor productivity studies to be used anecdotally by its members. In 2011, a true “labor productivity expert” would or should never base his/her opinions on these studies. Please contact Holloway Consulting at 888-545-0666 to discuss your labor productivity claim.
