Abstract
Material management is a key process for the success of a construction project. Typically in a construction project, material accounts for 50-60% of the total project cost. Non-availability of material when required, potentially impact the construction project causing time overrun, cost overrun, and loss of productivity. Due to the complex nature of construction projects, it is difficult to measure the impact of non-availability of materials. It is essential to prioritize materials for procurement based on the impact of their non-availability, especially in the budget constraint situation. However, in practice criticality of materials in procurement has not been considered and also very few studies have been reported in this area. We propose, the total criticality (TC) of material for prioritization of materials for procurement in budget constraint situation and as a measure of the impact of non-availability of materials. The TC of materials has been determined based on material criticality (MC) and activity criticality (AC). The AC has been obtained based on the float available for the activity. The MC has been determined using an integrated ANP-TOPSIS (analytic network process and technique for order preference by similarity to an ideal solution) approach which is a novel approach. This approach is employed with the additional criteria of MC such as environmental implication and volatility in price of materials along with the other reported criteria in literature such as percentage contribution, flexibility, lead time, customer’s specificity, and buyer’s dependence on suppliers. The ANP has been employed for determining weight of the criteria by considering their interdependencies and pairwise comparison as obtained based on a questionnaire survey within a group of experts. Further, TOPSIS has been adopted to determine MC values of materials based on the inputs from a construction project. The reported study will help in timely and budgeted completion of construction projects.

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
