Earthwork projects involve moving specific amounts of earth from a discrete set of source locations to a discrete set of destinations. Constructors use different methods and equipment to move earth depending primarily on haul distance and equipment availability. Successful earthwork projects involve successively refined cycles of construction plan(More)
It is argued that the two principal components of simulating earthmoving operations are modeling and providing input data. The knowledge and proficiency in modeling has been substantially improved through general purpose simulation systems such as CYCLONE and STROBOSCOPE. However, the inability to provide statistically reliable input data to the models is(More)
The global positioning system (GPS) makes use of extremely accurate measures of the time to determine position. The times required for electronic signals to travel at the speed of light from at least four orbiting satellites to a receiver on earth is measured precisely and used to calculate the distances from the satellites to the receiver. The calculated(More)

(ABSTRACT) Simulation modeling and visualization can substantially help in designing complex construction operations and in making optimal decisions where traditional methods prove ineffective or are unfeasible. However, there has been limited use of simulation in planning construction operations due to the unavailability of appropriate visual communication(More)
Construction operations can be categorized as either routine and repetitive or unique and complex. The means of developing an understanding of operations in each category differs. An understanding of routine and repetitive operations is best developed through analysis of field operations. Unique and complex operations by their very nature have not been(More)
