Pregenzer, L J; Seppanen, P J; Kunz, J C and Paulson, B C (1999) Value-added assessment of construction plans. Journal of Construction Engineering and Management, 125(4), pp. 242-248. ISSN 0733-9364
Abstract
In the purchase of a constructed facility, the buyer values those components that are in place when the user occupies the building. A task of placing or assembling such a component is therefore 'value-adding' (VA). This paper presents a method to classify construction tasks as VA, contributory, or ineffective to assess the valued-added by individual activities, as well as the aggregate value-added effectiveness of the construction plan. Current approaches to evaluate construction operations are based on limited examples rather than general rules. The proposed method presents a list of nine rules that are applicable to various construction trades. This paper provides for the value-added classification rules, specifies how to decompose activities for value-added analysis, and presents an illustrative test case. The proposed method can be used to assess the overall planned effectiveness of a detailed construction plan or the actual effectiveness of a construction operation. A case study of masonry wall construction indicates that the method requires significant understanding of the evaluated operation and task precedence relationships to classify activities properly. The use of this method for construction plan assessment enables a contractor to identify and potentially eliminate or reduce non-VA tasks, as well as predict the value-added effectiveness of a plan.

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
