Borges, W F and Mário, P D C (2017) Five project-duration control methods in time units: Case study of a linearly distributed planned value. Journal of Construction Engineering and Management, 143(6): 05017002, ISSN 0733-9364
Abstract
Changes in projects often affect planned performance. Earned value management (EVM) is a performance measurement methodology to control costs and scheduling by evaluating project progress using monetary values. Complementary methods to control project duration in time units were developed. This study contributes to project management by showing how to control costs, schedules, and time variances, given changes in quantity, resource costs, and productivity to identify the responsibilities of a contractor and owner for variations in time and cost. This study addresses the main methods for controlling project time variance in time units, as obtained through an extended literature review, and utilizes these methods by applying data from a real-life project. The findings indicated that in the case of a linear distribution of planned values, four of the five methods yielded identical values for the time variance to date and one of the methods depends more on the number of parallel activities in progress or completed.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
