Delay Analysis Methods for Construction Projects: Mathematical Modelling

Delay is quite common in construction project. A variety of factors contribute to the delay of project completion in the complex interdependencies of a number of tasks. Hence determining the contractual responsibility of delay is the most likely source of dispute in construction projects. Methods used for forensic investigation of delay are called as ‘delay analysis methods’. Although authoritative societies such as SCL (Society of Construction Law) and AACEI (Association for the Advancement of Cost Engineering International) have published guidance for implementing delay analysis methods, those are explained by a natural language, i.e. English, not by a formal language. On the other hand, process control of construction projects heavily relies on CPM programming based on the network modelling technique of which concept is described in a formal manner. The ambiguity of methods due to the lack of guidance on delay analysis methods described in a formal language may allow delay analysts to implement in different ways. Utilizing the mathematics as a formal language to explain delay analysis methods should contribute to reduce the degree of ambiguity of delay analysis methods and hence the possibility of dispute occurrence. This paper aims to formalising delay analysis methods commonly applied in practice employing the mathematical language.
