The job site productivity of the power shovel per day (in Example 4-11) is 504 cubic yards, which will be modified by a swell factor of 1.1. The only factors affecting the job site productivity of the dump truck in addition to those affecting the power shovel are 0.80 for equipment idle time and 0.70 for management efficiency.
Yes concrete does have an energy input cost but compared to other building material it performs better and is a safer construction material, A concrete building or bridge does not fail in the same way as steel, concrete will show signs of warning long before failure. Just remember that many early concrete structures last for hundreds of years.
Transporting the concrete mix is defined as the transferring of concrete from the mixing plant to the construction site. The main objective in transporting concrete is to ensure that the water-cement ratio, slump or consistency, air content, and homogeneity are not modified from their intended states.

level of national production in most developing countries, are inﬂuenced by a com-plicated network of factors as shown in Figure 1, below, of which half are outside the control of the farmer. A basic understanding of the inter-relations between factors affecting production is an essential prerequisite for an accurate assessment of production.
Other factors such as the level of skill amongst the workers and work practices and length of workday can affect productivity on construction site. A further research by Proverbs et al. (1999) into construction resource and productivity level for high rise concrete construction was conducted among contractors across France, Germany and UK.
Workability of concrete is measured in terms of the ease of mixing and placing of concrete. Highly workable concrete can easily be mixed, placed and transported. All the materials and processes involved in producing concrete affect the workability of concrete. Factors Affecting the Workability of Concrete
ument, "Productivity in Construction." I hope that it receives the attention it deserves and that every supervisor of construction projects refers to it frequently for guidance. Stephen G. Revay, F.EIC, F.CSCE Past President ( 1989-90) CSCE • PRODUCTIVITY IN CONSTRUCTION
May 09, 2019 · In this guide, we outline each of those factors. Summary – Factors That Affect How Plants Grow. It is often said there are 5 main factors that directly affect plant growth and a plant’s hormones (positively and negatively) – Light (sunlight), temperature, water, humidity and nutrients. But, this is a simplistic view, and in reality there ...

Apr 09, 2019 · Unless and until the adequate plant and machinery are installed, it is impossible to increase productivity compared to other similar organizations of industry. Similarly the maintenance of plant and machinery is also crucial for increasing organizational productivity. Few plant and equipmernt parameters affecting productivity are as follows:
Besides the climatic conditions and temperature, other environmental factors also play a crucial role and can affect the productivity of concrete batching plants. These are, composition of the atmosphere, radiant energy, moisture supply, soil structure, composition of the soil air, biotic factors, soil reaction, supply of nutrients to the soil, or no growth inhibiting substances.
Obviously construction factors are the most controllable and adaptable of all the factors affecting compaction. Although some factors like haul distance/time, HMA production temperature, lift thickness and type/number of rollers may be somewhat predetermined, other factors associated with roller timing, speed, pattern and number of passes can ...
