estimation of the conceptual costs in construction projects can be regarded as an important issue in feasibility studies. this estimation has a major impact on the success of construction projects. indeed, this estimation supports the required information that can be employed in cost management and budgeting of these projects. the purpose of this paper is to introduce an intelligent model to im...

this paper presents a prediction model based on a new neuro-fuzzy algorithm for estimating time in construction projects. the output of the proposed prediction model, which is employed based on a locally linear neuro-fuzzy (llnf) model, is useful for assessing a project status at different time horizons. being trained by a locally linear model tree (lolimot) learning algorithm, the model is int...

Construction industry is highly risk prone, with complex and dynamic project environments creating an atmosphere of high uncertainty and risk. The industry is vulnerable to various technical, sociopolitical and business risks. The track record to cope with these risks has not been very good in construction industry. As a result, the people working in the industry bear various failures, such as,...

This paper addresses the need to “know why” we build by looking first at the systemic nature, and complexity, that informs the construction industry’s current paradigm. An objective of this paper is to present how the construction industry’s reigning paradigm is driven by an entrenched and obfuscating manufacturingindustrial-engineering mindset. This obfuscation is not abnormal. According to Ku...

15 16 DIVERCITY is a large EU funded project in the area of construction IT undertaken by a European 17 consortium of researchers and practitioners from the construction industry. It is the acronym for 18 Distributed Virtual Workspace for enhancing Communication within the Construction Industry and 19 the prototype that presents the mechanism to smoothly and collaboratively conduct the construc...

recently, offshore and ocean engineering have been dealing with novel materials that play a significant role in reducing the weight of structures used in the ship construction industry. 5xxx series of aluminum alloys are of the novel alloys are suitable for construction of ship hulls and the topside structures of offshore platforms. within different 5xxx aluminum alloys, aa5083 is of great impo...

In this paper, supply policy and procurement of shared resources in some kinds of concurrent construction projects are investigated. This could be oriented to the problems of holding construction companies who involve in different projects concurrently and they have to supply limited resources to several projects as well as prevent delays to any project. Limits on transportation vehicles and st...
