A comprehensive review of this publication has been offered by Mr. Charles Choyce.  This review and discussion can be seen at this link.

MCAA [Mechanical Contractors Association of America, Inc.] is, of course, an advocacy organization.  Managers should keep the obvious in mind when applying the MCAA tools.  Never-the-less, these tools are professional, widely distributed, well accepted and valuable.  The application is not limited to just mechanical construction.  The methodology and techniques have widespread applicability.  Mr. Choyce indicates that the electrical contractors [NECA] and sheet metal contractors [SMACNA] organizations have endorsed this publication.  The applications are even more widespread.

M&M has used MCAA products, including this publication, for many years.  This use included applications as engineering and construction contractor (mechanical and electrical), owner organizations (contract project manager) and in consultant assignments dealing with claims, disputes and litigation.  In the right situation, this and other MCAA tools can be very helpful in framing, evaluating and resolving changed situations, particularly in larger and more complex projects.

Project professionals should approach the issue of project management with consideration for labor/labour productivity and with all other factors in an integrated manner.  Labor productivity must be integrated with other related aspects of program and project execution planning or forensic analysis.  In planning for these practices, consideration must be given to progress planning, labor/labour crew requirements, progress impacts and professional forecasts.  The managerial approach should include methods and Key Performance Indicators (KPI’s) that provide the feedback needed to detect and identify variances from the Project Management Plan baseline.  The MCAA publication can be useful in the planning and contracting process.
