Effect of the organization and methods of earth and rock excavation work on the time and economic effectiveness of the construction of the Irtysh-Karaganda canal

Conclusions

Investigation, organization, and introduction of the brigade method of earth-rock excavation work by heavy excavators with payment for a finished stretch during construction of the Irtysh-Karaganda canal gave the following results:

• 1. An increase in the sense of responsibility of the workers for the work entrusted to them and a mobilization of their creative initiative in solving construction problems; increase in labor productivity of the workers and output of the excavators by fourfold; improvement in the quality of the work performed and of the skill of the machine operators; marked reduction in the construction time; considerable decrease in uncompleted construction.

• 2. Still another national economic experiment was checked in practice — the expediency and need for converting hydraulic construction to stagewise accounting with the client for work accomplished. Practice showed that this method of hydraulic construction, as in construction in general, is progressive and has a number of advantages in comparison with accounting on the basis of flat rates.

• 3. The most vital and effective system promoting the maximum intensification of construction is that system in which the material interest in the most rapid completion of structures extends primarily to the immediate doers — the workers - and the system of paying the workers corresponds to the system of the client's accounting with the contractor for work performed.

• 4. It is possible and expedient to place the canal in operation as its individual stretches are completed.

• 5. The brigade method can be introduced at any construction project, it should be the main method of performing earth-rock excavation work in hydraulic construction and also on the construction of industrial and transportation projects with large volumes and intensity of earth-rock excavation.
