An integrated framework for sustainable construction processes: understanding and managing the environmental performance of construction operations
The environmental impact from construction activities has largely been underestimated, even though these processes constitute significant economic activity. They account for a substantial amount of Greenhouse Gases (GHGs) and other diesel emissions, such as nitrogen oxide (NOx) and particulate …

The management of construction processes in developing countries : a case study of the Ethiopian Roads Authority
The delivery of construction projects in Ethiopian is accused of non-optimum performance. With this poor performance of the delivery of projects as the instigator, this study set major objectives of exploring the current practices of the management of the construction processes in Ethiopia and …

Precisely Loose: Unraveling the Potential of Particles
… non-normative materials—particles, encompassing construction demolition debris, manufacturing defects, naturally occurring gravels, and locally sourced mineral waste. Ubiquitous yet underutilized, these materials hold potential not only for use, but also for reuse. However, they are often …

Dynamic planning and control methodology for large-scale concurrent construction projects
Concurrent construction has been widely used for modem construction projects, as a method to shorten time-to-market. Concurrent construction, however, requires a careful and systematic approach to its planning and management, since it also has greater potential to impact the construction process …

Robust control of cost impact on fast-tracking building construction projects
… manner. A closer observation of the design and construction process reveals that all of the cost-increasing factors in fast-tracking are directly or indirectly related to non value-adding or corrective changes. These changes are mainly attributed to uncertainty that is rooted in the …

Applications of Genetic Algorithms for Multi-Objective Resource Allocation of Construction Projects Under Certainty
… as the foundation for multi-objective construction process optimization. Based on GA principles, a set of algorithms is developed specifically for construction process analysis and optimization. This set of algorithms is also integrated with simulation techniques to analyze risks and …

Thin shell foundations: Embodied carbon reduction through materially efficient geometry
… gas emissions annually as a result of current construction processes. Therefore, if global warming is to be limited to 1.5ºC above pre-industrial levels, reducing embodied carbon will play a key role and business-as usual construction processes must be reconsidered. This research aims to reduce …

Hydrologic Variations Within Created and Natural Wetlands in Southeastern Virginia
… wetland systems function. In created wetlands, construction processes and materials influence the hydrology and consequently, the potential for successful reestablishment of target vegetation communities. During 2002–2004, the Virginia Department of Transportation constructed large mitigation …

Dynamic Planning and control Methodology : understanding and managing iterative error and change cycles in large-scale concurrent design and construction projects
Construction projects are uncertain and complex in nature. One of the major driving forces that may account for these characteristics is iterative cycles caused by errors and changes. Errors and changes worsen project performance and consequently, cause schedule and cost overruns to be prevalent. …
