Abstract
The study substantiates the need to improve the existing technology of earthworks in megacities. The use of alternative types of over-ground transport technological machines would change the management and process control algorithm, increase performance efficiency and quality of operations, reduce costs for procedure implementation. Shortcomings of the existing technology of earthworks in the space-limited urban environment are analyzed. An implementation procedure for the existing technology to carry out operations with the use of transport technological machines and auxiliary equipment is presented. The study also substantiates the need for practical application of such alternative type of over-ground transport technological machines as the vacuum excavator during earthworks. A set of transport technological machines for earthworks based on the improved technology with the use of the vacuum excavator was formed; space-limited conditions of megacities were taken into account.
