Abstract:
ABSTRACT The special nature that characterizes construction projects in Iraq,
the multiplicity of its stages from the idea stage to the end of the delivery
stage, and the weakness in the application of risk management makes it
vulnerable to many risks that have a unique impact on its basic
objectives. The identification and management of risks in construction
projects is an important approach to reduce their impact and increase the
chances of success of the construction projects
The research aims to identify the most important risk factors facing
construction projects in Iraq, provide a tool based on the integration
between risk management and BIM technology to manage the risks that
effect the duration of construction projects, and help the project manager
to understand the impact of risk management and taking measures for
controlling the risks in construction projects.
In order to achieve the research objectives, the literature and
previous studies related to the topics of risk management and BIM
technology were reviewed and selects one of the Iraqi projects as a case
study for applying the idea of the research. After that, the researcher
identifies and assesses the risks that face the construction projects by
using qualitative and quantitative techniques represented by the
VIII
questionnaire, personal interviews, probability and impact matrix, Monte
Carlo simulation. Finally conducting the integration between risk
management and BIM through using tools provided by the BIM
technique (Autodesk Revit 2020, Navis work manage2020) that helps for
achieving the research objectives
The study diagnosed 48 risk factors that represent the most
common risks in construction projects in Iraq, and reached a predictive
model for risks by adopting two scenarios for the likelihood of risk
occurrence and its impact on construction projects. From the approved
scenarios comparison, the probabilistic percentage for completing the
project was 109% of the planned percentage of project completion, and
for the pessimistic scenario the probabilistic percentage of project
completion was 334% and 774% for (case 1) and (case 2), respectively.
The integration between risk management and BIM technology is a
simulation of a 4D building model that visuals the effect of risks on
project progress and shows the delayed activities and allows the
comparison between the planned and actual project progress in a visual
format.
