According to the Society of Construction Law (), disruption is “a disturbance, hindrance or interruption to a Contractor’s normal working methods, resulting in lower efficiency. Disruption claims relate to a loss of productivity in the execution of particular activities. In a recent Construction Briefings article by Kathleen Harmon, the author breaks down loss of productivity claims based upon a claim of acceleration to overcome excusable delays, or a claim for cumulative impact of an owner’s changes project.

Factors Affecting Construction Labor Productivity 6 6. Factors Affecting Labor Productivity There are many factors that affect the productivity of labor in construction. These are generally set forth in publications or manuals made available through associations like the Mechanical Contractors Association of America (MCAA) and other organizations. Abstract: The calculation of lost labor productivity is controversial because of the widespread skepticism of those owners (or even general contractors) against whom such claims are asserted, as well as triers-of-fact, who may come to view the methodologies employed to calculate both the extent and value of the asserted damages as questionable, speculative, and illusory.
For instance, in a construction job-site where the ready-mixed concrete of m 3 is poured in 5 days, labor productivity is day per m 3. However, in terms of numerical comparisons, a more convenient way of calculating labor productivity rates in the construction industry is the opposite of this definition. It is a difficult and challenging task to quantify lost labor productivity in construction claims. Project-specific studies, such as the measured mile analysis, for calculating loss of productivity are generally more preferred than project comparison studies, industry studies, and cost-based methods.
