Introduction • Operations involved in Construction of any Project Excavation Digging of large quantities of earth Moving them to distances which are sometimes fairly long Placement Compacting Leveling Dozing Grading Hauling • Operations involved in Construction of any Project Excavation Digging of large quantities of earth Moving them to distances which are sometimes fairly long Placement Compacting Leveling Dozing Grading Hauling 2 February 2019 COTM 4202 2
  3. 3.  Construction projects require heavy equipment to execute many of the activities.  In the case of huge construction projects; proper use of the appropriate equipment contributes to economy, quality, safety, speed and timely completion of a project.  We use heavy equipments for construction of highway projects, irrigation, buildings, power projects etc.  15-30% of total project cost is accounted towards equipment and machinery. • Evolution of Construction Equipment Introduction  Construction projects require heavy equipment to execute many of the activities.  In the case of huge construction projects; proper use of the appropriate equipment contributes to economy, quality, safety, speed and timely completion of a project.  We use heavy equipments for construction of highway projects, irrigation, buildings, power projects etc.  15-30% of total project cost is accounted towards equipment and machinery. 2 February 2019 3 COTM 4202
  4. 4. Introduction • Role of Heavy Construction Equipment • As technology transferred construction equipment is designed specifically to perform certain operations • Construction activities require different types, sizes, and groupings of equipment for:  earth moving,  excavating, and  lifting. • The development of heavy construction equipment occurred in the last two centuries • Role of Heavy Construction Equipment • As technology transferred construction equipment is designed specifically to perform certain operations • Construction activities require different types, sizes, and groupings of equipment for:  earth moving,  excavating, and  lifting. • The development of heavy construction equipment occurred in the last two centuries 2 February 2019 4 COTM 4202
