Earthwork, an essential activity in most construction projects, consumes large quantities of fossil fuel and produces substantial air pollution with adverse environmental impacts. To achieve more sustainable processes, novel methodologies to evaluate improve the performance earthwork operations are required. This study quantifies real-world emissions consumption equipment within project China. ...

As a continuation of the authors’ research presented in previous years (ISARC), these authors focus on the processing aspect of the 3D terrain models acquired from heterogeneous 3D scan sources. This includes a revision of the authors’ ICP-based merging algorithm to achieve better accuracy in the ever-changing shape of an earthwork site with acceptable penalty in speed, and the introduction of ...

Dust generated in earthwork construction activities can seriously affect the air quality at a site and have adverse effects on health of workers. To accurately quantitively analyze distribution characteristics dust effect prevention measures during under normal with control measures, multiple collection points one meteorological parameter point were placed site. From half an hour before to afte...

Abstract Research in 1970 vaulted Becán to prominence on the landscape of great Maya centers. Mapping, excavation, and ceramic stratigraphy revealed that its enigmatic earthwork, first recorded archaeologically 1934, was a fortification built at end Preclassic period. Large-scale warfare thus unexpectedly turned out have very deep roots lowlands. The site's wider implications remained obscure, ...

Since the Fourth Industrial Revolution, existing manpower-centric manufacture has been shifting towards technology and data-centric production in all areas of society. The construction sector is also facing a new paradigm called smart with clear purpose improving productivity securing safety by applying site management using information communications (ICT). This study aims to develop framework...

The earthwork volume must be calculated as accurately possible for economical construction and cost savings. In particular, when calculating the areas volumes of irregular curved terrains such mountains, reservoirs, lakes, coasts, vertical assumptions boundary equation rationally systematically established. This study focuses on calculation technology using UAV (unmanned aerial vehicle). can us...
