Hierarchy of Obstacles to Application of Design Build Methods in Road Infrastructure Project Procurement : A Delphi Study

Abstract

Currently the procurement of road infrastructure projects in Indonesia is mostly carried out using Design Bid Build (DBB), in which the project planning and construction processes are contracted separately. Although this method is well known in its implementation, the long procurement period often results in the slow procurement of infrastructure projects. As an alternative to the procurement method is the Design Build method. This method is believed providing many advantages compared to traditional methods. However, in practice there are obstacles that can hinder the application of this method. The purpose of this study is to analyze the herarchy of the obstacles to applying the Design Build method and formulate efforts to overcome these obstacles. A two-round paired matrix questionnaire survey using the Delphi technique was distributed to obtain consensus from the stakeholders involved in the infrastructure project procurement process. Subsequently, an Interpretive Structural Model (ISM) analysis is carried out to obtainthe hierarchy and the relationship between the constraints that can hinder the implementation of the Design Build method. Fourteen constraints were identified, which form a six-level framework that needs to be addressed in implementation.

Evaluating quality management of road construction projects: a Delphi study

“…The participants were asked to reconsider and re-evaluate their answers by answering “yes” or “no” to the questions. An agreement measurement approach of “yes” or “no” in the research area of construction was also employed by Dewi (2013). A review of a wide range of Delphi studies revealed that there are different methods for measuring consensus (Sourani and Sohail, 2015).…”

“…Civil construction projects in Indonesia are frequently criticized by the stakeholders because of low-quality results (Mubin and Latief, 2019), such as poor road conditions, which are generally far from satisfactory (Dewi, 2013). Therefore, expectedly, a government program was launched to improve the quality of road projects.…”

“…Currently, the Indonesian road infrastructure is inadequate to sufficiently service the entire country (Dewi, 2013). Therefore, the Indonesian government launched the National Strategic Projects in Infrastructure initiative, aimed at improving national interconnectivity by developing transportation infrastructure networks (Agustiawan, 2020).…”

“…Governments of developing countries such as Indonesia must be aware that the speed of development of road infrastructure should be aligned with its quality. Thus, improving the quality of Indonesian road infrastructure is critical (Dewi, 2013). Global Competitiveness Report 2019 ranks the quality of Indonesian road infrastructure at 60, behind those of Singapore (1), Malaysia (19), and Brunei (32) road infrastructures (Schwab, 2019).…”
