Flexible Design Build Method, Applicable for Delivery of Large Industrial Projects in Complex Environmental Situations: Case of Projects in Oil Industry of Iran under Sanctions

Uncertainties and risks underpinning environmental complexities have undermined lots of assumptions and delivery methods of large industrial projects and have lessened their efficiency and effectiveness. In the literature، selecting proper project delivery method in complex situations still lacks attention، and existing relevant studies have been also conducted based on “the first order of project management”، in which the degree and extent of uncertainties and environmental complexities are considered normal and prevalent. Based on the recent scientific and managerial paradigms such as “the second order of project management”، it is necessary to fulfil required revisions in existing models and solutions، utilizing a novel comprehension and vision to the environment. The main aim of this article is proposing an appropriate method for industrial projects delivery which are planned and conducted in environmental complex situations (and especially high uncertainties as subsequent of situations). This study shows that usual Design and Build method (EPC/TK) – with maximum transferring of risks to contractor – does not satisfy executing large industrial projects، and it should be improved through correction of basics and application of innovative tools and techniques. Flexibility Increasing، sharing risk among parties، supporting problem solving approach، etc. in delivery method form the basis and ground.
