NECA Releases Updated Manual of Labor Units

Nov 02, 2015

New Manual of Labor Units Now Available in the NECA Store 

An estimate is only as good as the information it’s based on, and the NECA Manual of Labor Units (MLU) is the estimating resource of choice for electrical contractors since 1923. The 2015-2016 edition of the Manual of Labor Units is now available in multiple forms for purchase. 

The MLU provides an experience-based reference for estimating the electrical construction labor required to install typical electrical and communications systems. It is an invaluable resource to NECA members when estimating projects. 

“NECA is the leader of the electrical industry, and the Manual of Labor Units is a primary example of that,” said Jim Peterson of Berwick Electric Co. “It's developed by NECA contractors and continuously updated to keep employers abreast of new technology and products. The electrical industry is evolving more rapidly than ever before, and accurate estimates are the foundation of a successful business. The MLU is a reliable resource for our estimating team and a tool that we use every day. For anyone just starting their business or those with years of experience, the MLU is a must-have.”

Each revision cycle, a team of estimating experts chosen from NECA members across the country review the manual and update existing items and add new ones where appropriate. This year, changes and additions were made to the labor units throughout the manual, but the most significant change was in how these units are selected. The Labor Factor Score Sheet, which determines which column of labor units should be selected based on the installation conditions, was revised to recognize a larger range in the conditions that may affect installation.

NECA’s labor units include:

  • normal material handling;
  • drawing study, measurement and layout;
  • material installation;
  • and normal non-productive labor.

All electrical construction requires more than one level of supervision, and the magnitude of supervision depends on the complexity, type, and size of each project. Because each project is unique, it is the opinion of most electrical contractors that the labor for supervision is best estimated as a separate cost item and that no part of the supervision labor be included in the material installation labor units. 

Ordering the MLU

The Manual of Labor Units (MLU) is available as a hardcopy book, CD, digital download, and as a companion subscription to TRA-SER in NECA’s Store, www.necastore.com.
