Abstract
Environmental pollution is considered to be one of the main concerns in the construction industry. Environmental pollution has become a major challenge to construction projects due to the huge amount of pollution caused by construction projects. There are different types of environmental impact indicators, such as the greenhouse gas (GHG) footprint, eutrophication potential (EP), acidification potential (AP), human health (HH) particulate, ozone depletion, and smog. Each of these environmental impact indicators can be linked to different phases of the construction projects. The overall environmental impact indicators can be divided into direct, indirect, and operational emissions. This paper presents a Building Information Modeling (BIM)-based methodology for the assessment of environmental impacts in road construction projects. The model takes into account the overall life cycle of the road construction project, which is divided into: manufacturing phase, transportation phase, construction phase, maintenance phase, operational phase, recycling phase, and deconstruction phase. A case study is presented to demonstrate the applicability of the proposed model. The proposed model solves a major problem for road construction project teams who want to assess the environmental impact indicators associated with their project prior to the start of the execution of their projects.
Highlights
Infrastructure construction projects in general and road construction projects are associated with a huge amount of emissions that vary from the start of project execution until the demolition stage [1]
A three-dimensional Building Information Modeling (BIM) module was developed that is capable of computing time, life cycle cost, overall environmental impacts, and primary energy associated with road construction processes, using Revit 2015 software, the Athena Impact Estimator, and Copert software version4
The results obtained from the model demonstrated that the environmental impact indicators have negative consequences for both the environment and individuals
Summary
Infrastructure construction projects in general and road construction projects are associated with a huge amount of emissions that vary from the start of project execution until the demolition stage [1]. This pollution can affect human health and the economic balance in a very severe matter [2]. Primary energy can be divided into renewable and non-renewable energy Use of these natural resources during the construction, operation, and maintenance stages of the project is associated with environmental impact indicators. Umer et al [7] developed a sustainability assessment hierarchal model for roadway projects under uncertainties using a green-based index approach to evaluate how well the project meets sustainability objectives in order to illustrate how well the roadway project is meeting its sustainability objectives
