System Dynamics Approach for Error and Change Management in Concurrent Design and Construction

<p>The Trysfjord bridge is a concrete balanced cantilever bridge with a main span of 260m, being built at the present time and will, when finished, be among the largest bridges within its type. The bridge is part of the E39 highway under construction between Kristiansand and Mandal in the southern part of Norway. The concurrent design and construction process are being done with parametric analysis and modelling (PAM) as well as building information modelling in x dimensions (4D, 5D, xD, BIMxD).</p><p>This design and building project utilize the underlying power of computers not directly accessible through commercial software, by programming our own adapters and pre-/postprocessing algorithms in Dynamo, Python, and C#. This is creating new connections between the profession of computer programmers and civil engineers. Different layers in the architecture from calculations to modelling is also coupled.</p>

The future of mega infrastructure projects is certain - there will be more risks to manage! The challenge is being met through research and innovation combining current approaches with new. This research adopted a dynamic approach through the combination of Analytical Network Process (ANP) and system dynamics (SD) as an innovative methodology known as SDANP to model complexity in megaprojects design and construction. Wecommunicate how the SDANP model could explore problems caused by Social, Technical, Economic,Environmental and Political (STEEP) risks to construction cost, time and performance and provide insights thatlead to organizational learning. We proceed to exemplify by means of a real-life case project in the City ofEdinburgh and offer suggestions on what front-ended stakeholders could do to improve the management of risks in megaprojects. The results of the application showed that, when compared to traditional risks assessment methods, this SD model with integrated ANP revealed improvements in managing risks according to STEEP risks criteria. The new framework appears to be a superior solution for solving the dynamic complexities of risks during megaproject design and construction. The findings of the study contribute to the project management theoretical development within the field of megaproject management.
