Many studies have been conducted on the contributions of the construction industry to greenhouse gas (GHG) emissions. However, these studies focused on the embodied GHG emissions of buildings and were restricted by limited system boundaries due to a lack of detailed on and off-site process data, especially data for assembly and miscellaneous works as well as construction related human activities. This study therefore analyzed GHG emissions during the construction phase of a case study building on the basis of an extended system boundary in the context of China by utilizing detailed onsite process data. The results show that indirect emissions accounted for 97% of all GHG emissions. On-site electricity use and building materials production were the two greatest contributors to direct and indirect emissions respectively. Recombining the construction activities revealed that construction related human activities generated significant GHG emissions (385 tCO2e), which have been ignored in previous research. The findings also reveal that although some materials used during the construction process are negligible in terms of weight, such as polyamide safety nets and aluminum (<0.1%), they have a considerable impact on GHG emissions (2-3%).

“…Son et al [5] presented their achievements for the period of 1990 to 2005. Horizontal alignment [6][7][8][9][10][11] and environmental consideration [12][13][14][15][16][17] are other aspects of this subject. During the recent decade, some researchers have developed models in rock waste dump management, aiming to reduce the cost associated with waste rock haulage from the pit toward proposed destinations [18][19][20].…”

Today, during the life of an open pit mine, million tons of materials, including waste and ore, are displaced by truck fleets. In the case of a shallow ore deposit, which is located up to 300 meters to the ground surface, depending on preliminary equipment size and capacity, it will take three to five years to remove overburden and waste rocks to expose the ore body. In that period, the main waste dump site will be used as a disposal of waste dump. Apart from considering the characteristics of the waste dump location such as geological and geotechnical properties, the major factors influencing the hauling process are topography, hauling length and construction cost of the haul road. Truck transportation cost depending on the circumstances comprises 45 to 60% of the cost of mining of one tonne ore. Thus, well site selection of waste dump in coordination with the main haul road path confidently leads to a significant saving of economic resources. In this research, while identifying the effective factors in selecting the waste dump sites, a linear mathematical model is developed to find a suitable site for waste dump disposal considering minimizing haul road construction cost.

The framework was applied to 23 typical highway construction projects in the Republic of Korea [ 2 ]. The project also studied the GHG emissions from onsite equipment usage during road construction, and summarized the eight major GHG-producing activities during the construction [ 3 , 4 ].…”

In China, the construction of asphalt pavement has a significant impact on the environment, and energy use and greenhouse gas (GHG) emissions from asphalt pavement construction have been receiving increasing attention in recent years. At present, there is no universal criterion for the evaluation of GHG emissions in asphalt pavement construction. This paper proposes to define the system boundaries for GHG emissions from asphalt pavement by using a process-based life cycle assessment method. A method for evaluating GHG emissions from asphalt pavement construction is suggested. The paper reports a case study of GHG emissions from a typical asphalt pavement construction project in China. The results show that the greenhouse gas emissions from the mixture mixing phase are the highest, and account for about 54% of the total amount. The second highest GHG emission phase is the production of raw materials. For GHG emissions of cement stabilized base/subbase, the production of raw materials emits the most, about 98%. The GHG emission for cement production alone is about 92%. The results indicate that any measures to reduce GHG emissions from asphalt pavement construction should be focused on the raw materials manufacturing stage. If the raw materials production phase is excluded, the measures to reduce GHG emissions should be aimed at the mixture mixing phase.
