requirements. Equipment production-estimating procedures discussed in this manual help quantify equipment productivity. PRODUCTION ESTIMATES Production estimates, production control, and production records are the basis for management decisions. Therefore, it is helpful to have a common method of recording, directing, and reporting production. (ANN) has the potential to improve the equipment productivity estimation model. Keywords: Construction equipment, artificial neural network, productivity estimation Introduction An accurate prediction of the productivity of earth-moving equipment is one of the prerequisites for construction project control and planning. This study. The developed methodology utilizes global positioning system (GPS) and Google Earth to extract the data needed to estimate productivity of the tracked operation. A GPS device is mounted on one of the hauling units to capture the spatial data along hauling roads considered for the project.

earthmoving and heavy equipment industry has always operated in a very competitive environment. For decades, cost- effectiveness and productivity have been. only to predict productivity but also to predict earthmoving machinery effectiveness ratios were also reported . Construction Companies in India have neither. Key Words: Construction equipment, Nominal hourly production, Actual hourly production, Earth-fill dam projects. 1. accurate estimation of earthmoving hourly production These non-productive time elements include. Estimating equipment production rates is both an art and a science. An accurate prediction of the productivity of earthmoving equipment is critical for accurate. equipment common in the South. In addition, published informa- a. tion on productivity rates for equipment used in harvesting southern.
rate and unit cost for production of construction equipment. Analysis is performed on six different earth moving equipments for time span of 15 years. It is shown that production rate has increased % on average per year. The unit price of production has increases % on an average per year. in calculating productivity for a particular piece of equipment or a particular job is a function of the specific work-task being analyzed. To make accurate and meaningful comparisons and conclusions about production, it is best to use standardized terms. • Production rate. The entire expression is a time-related production rate. Earth moving Equipment (Earthmoving Machinery): 1 BULLDOZERS: BULLDOZER Earth moving Equipment. A bulldozer is a tractor unit with a blade attached to its front. and it is effective Earthmoving Machinery •The blade is used to push, shear, cut, and roll material ahead of the tractor. It is. an ideal surface earthmover that performs best at about 3 mph. Equipment Productivity Enter Table and select an average production rate based on a wo r60 min/hk time ofrSelect the. column headed by a LCY bucket payload and the row that represents a min cycle time. From this, the average production is determined to be LCY per min hr. **Equipment production** The Equipment that will be covered on the exam and in this section are; Dozers Graders Scrapers Loaders Excavators Cranes (will .
