The measure of the rate at which work is performed is called productivity. It is a ratio of production output to what is required to produce it. The measure of productivity is defined as a total output per one unit of a total input. In construction, the output is usually expressed in
A mine measures cycle times to determine equipment performance and operator efficiency. Those statistics also serve as a measure of efficiency of the entire operation. Unusually high readings in certain segments can highlight problems. By measuring cycle times, benchmarks can be established, allowing a quick check that all is well.
Sep 10, 2014 Construction Civil Works Productivity Rates. Date September 10, 2014. Construction Productivity Rates are very important to both Site Engineers, and Planning Engineers. It could be used to monitor the labor performance, or to estimate the manpower required for a project for planning and monitoring purposes or for cost estimations.
Jan 25, 2019 The production cycle is the amount of time that the producer requires to create a production unit. Fictional Computers requires six minutes to produce a complete hard drive, so the production cycle for hard drives is six minutes. The maximum production rate is the production rate of a manufacturing process with no defects and no downtime. With a production cycle of six minutes,

Earth excavation and grading can be a fascinating part of a construction project. The powerful heavy equipment, used to best advantage by a skilled operator, is a joy to behold. The scope of the excavation job varies from digging footings for a small building to moving millions of cubic yards of earth.
Construction Contingency A standardized markup applied to the construction cost of a project that accounts for uncertainties in quantities, unit costs, and minor risk events that typically take place during construction. Refer to the . Plans Preparation Manual, Section 800.03, for guidance on estimating construction contingency.
In 2017, over 400,000 excavation accidents were reported in North America, and the pressing need for safer, less invasive equipment could no longer be ignored. By using vacuum excavation techniques, the risks involved in exposing or digging around utilities were nullified with a non-mechanical, non-destructive alternative, and there were two ...

planned production for a length of time falls under Unplanned Downtime. The possibilities of such events are equipment failuresbreakdowns, quality problems, material shortages, and most importantly, changeover time. Changeover time is the time wasted in between shifts i.e. a form of downtime that can be reduced. The remaining time is called Actual
