H IST O R Y O F D E V E L O PM E N T An opportunity to discuss the development of any product must include a bit of history so that having observed where we have been one may have a clearer perspective of where we are and may be going. This discussion will try to capture all of these facets. Construction projects of one type or another date back to times before recorded history. M an’s hands we...

a r t i c l e i n f o A common and extended Petri net simulation framework for virtual construction of earthmoving operations is developed to simulate dynamic changes of workflow and information flow in the earthmoving construction process and illustrate the constraint relationship between various operational equipment and construction restrictions. The proposed framework considers factors that...

The United States construction industry experienced 151 fatalities resulting from workers colliding with objects and equipment in 2009. These fatalities accounted for approximately 18% of the total construction fatalities and 3% of the total workplace fatalities experienced that year. Construction workers and equipment are often required to function at close proximity on construction jobsites. ...

Abstract With recent advancement in software, hardware, and computing technologies, applications of intelligent equipment robots (IER) are growing the construction industry. This chapter aims to review key advantages, use cases barriers adopting IER renovation projects. The evaluates maturity available technologies market discusses concerns for such as unstructured dynamic nature sites limiting...

Video recording of construction operations provides an understandable data that could be used to analyze and improve construction performance. Despite the benefits, manual stopwatch study of previously recorded videos can be laborintensive, may suffer from biases of the observers, and impractical after substantial period of observations. To address these limitations, this paper presents a new v...

With rising road construction and maintenance costs and the lack of productivity improvement, automated road construction and maintenance equipment will provide an attractive alternative for the execution of routine work tasks in the future. This paper reviews the typical tasks applicable to this domain, as well as existing and future automated equipment for task execution. The distinction betw...
