The activity duration is governed by the lowest production rate = 20 days. This is an unbalanced crew where the loader is not working with full capacity; the production rate of this crew could be adjusted by increasing the number of trucks to 4 of 5 trucks. Then, for a balanced mix of resources, use 1 loader, 1 excavator and 4-trucks.
The scheduling process in the design phase involves three key activities: (1) A production rate is calculated for individual work items, (2) the production rates from these work items are consolidated and lead–lag relationships are developed among them, and (3) a final schedule is developed using the Gantt chart or critical path method (CPM).
Production Rate: In manufacturing, the number of goods that can be produced during a given period of time. Alternatively, the amount of time it takes to produce one unit of a good. In construction ...
Construction equipment production rates are considered an influential factor in construction projects' success as 30–40% of construction cost overruns are attributed to insufficient equipment ...

construction production rate information for estimating project timelines. Minor production rate updates for 2024 were conducted via analysis of survey data from the Districts. TxDOT will review and update these rates, as appropriate, by March every two years. The following assumptions were made in the development of these rates.
The computation of the actual production of construction equipment is complex. But through idealization, approximation and in general simplification, one can arrive at an optimum result. Q ... Rate of hourly production P = (3600* Q *f * k * f1 *η )/Tc = (3600 * 1.14 * 0.8 * 0.9 * 0.81 * 0.83) / 19sec

Laws and principles of mechanics determine the capability and performance of construction equipment in completing each of the field operations. The driving power created by the power train of a machine must overcome the retarding forces at the desired speed and production rate for each type of operation.
2. Construction Equipment Productivity • Equipment productivity generally refers to the time during which the machine is in operation performing productive work. The more efficiently the workers can complete their tasks, the higher the production level is. • Poor equipment productivity is a leading contributor to many problems that …
A well-trained operator, working under suitable conditions, utilizing a modern, properly-equipped machine provides a machine-operator team capable of giving maximum production.
