Antoniou, F; Konstantinidis, D; Aretoulis, G and Xenidis, Y (2018) Preliminary construction cost estimates for motorway underpass bridges. International Journal of Construction Management, 18(4), pp. 321-330. ISSN 1562-3599
Abstract
This paper presents the total cost and cost distribution between activities required for the construction of reinforced concrete underpass bridges. The required material quantities of concrete, reinforcing steel, earthworks (excavation, soil improvement layer and backfilling), waterproofing works, joint formation and drainage system from 34 closed box section and slab frame underpasses from recent highway projects in Greece are statistically processed. Following analysis of this data, preliminary cost estimating formulae for underpass bridges are proposed based on the overpass deck surface area and a new parameter called the theoretical volume. The theoretical volume is a known value even at the preliminary stage of design as it is essentially the dimensions of the local road that must be realigned to underpass the motorway. It is suggested that the use of the proposed formulae will provide decsion-makers with accurate cost estimated of reinforced concrete motorway underpass bridges.

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
