The project of the organization of construction and the project of the work of the PIC and PPR

The project of the organization of construction and the Project of production of works are the main documentation on technology and the organization of works on construction of buildings and structures. The construction organization project is being developed in order to ensure the timely commissioning of production facilities and housing and civil facilities with the lowest cost and high quality by increasing the organizational and technological level of construction.

The project of the organization of construction is the basis for the distribution of capital investments and the volume of construction and installation works for the construction period, as well as the justification of the estimated cost of construction. The project for the production of works is being developed in order to determine the most effective methods for carrying out construction and assembly work to reduce their cost and labor intensity, reduce the duration of construction of facilities, increase the use of construction machinery and equipment, and improve the quality of construction and assembly work. Implementation of construction without the Project of the production of works is prohibited.

The project of the organization of construction and the project of production of works should be developed taking into account:

a) the use of progressive forms and methods of organizing planning and management

construction so that the duration of the construction of enterprises, buildings and structures does not exceed the normative;

Directory deadlines are the deadlines set by the investor (may be the government). Regulatory terms are determined by SNiP 1.04.03-85. In this SNiP on the basis of analogs of construction projects, the following data are given by industry, depending on the capacity: I

- total construction period (in months); including:

- preparation period;

- equipment supply (month, from one to another);

- installation of process equipment (total, and from such and such to such and such). In addition, given the reserves by quarter in% of the total cost.

Before determining the time, you should carefully read the technical part. SNIP.

b) ensuring timely preparation of facilities for the development of design capacity;

c) the use of modern technical means of dispatch communication and the introduction of automated control systems for the construction industry;

g) the use of technological processes that provide the required level of quality of construction;

e) complete delivery for the construction of structures, products, semi-finished products and materials per section, level, floor, etc .;

e) the priority of the work of the preparatory period;

g) maximizing the use of the scope of work, combining construction processes with ensuring their continuity and flow through the even use of resources and production capacity;

i) the introduction of integrated mechanization of work with the maximum use of the most productive machines in two shifts or more, as well as the use of small-scale mechanization;

j) the supply of technological equipment in integrated units;

l) limiting the scope of construction of temporary buildings and structures due to the use for the construction of permanent buildings and structures, the use of mobile, container collapsible and inventory buildings, structures and

mechanized installations, typical devices and inventory, as well as reducing the number and storage area at the construction site, through the installation of structures directly from vehicles;

m) of priority construction as part of industrial facilities of permanent residential and medical-prophylactic institutions, for the purpose of their temporary use by builders;

m) compliance with the rules on industrial hygiene, labor protection, safety engineering, as well as the requirements for explosive, explosion and fire safety;

o) the implementation of measures for the protection of nature and the recultivation of agricultural land and forest land disturbed during the construction and installation works.

In the development of the POS and the outage should take into account the climatic features of construction, the requirements of contracts for enterprises created on the basis of complete imported equipment and other local and special conditions.

When developing POS and CPD for the northern regions, it is necessary to take into account: physiographic conditions (a longer cold period with low air temperatures and, therefore, the need to use machines and mechanisms in the "northern" version, permafrost soils, polar day and night, small natural illumination of the territory in winter, territorial disunity of construction and the need for a complete supply of building materials and structures from developed industrial centers, seasonality in the delivery of resources, the need to use specialized modes of transport, the need to increase the costs of household and household equipment to ensure normal living conditions and activities of people, etc.

Also, its features in construction are in the mountainous areas, in the areas of deserts and semi-deserts. All of them must be considered.

The choice of decision options in the development of the PIC and the outage should be made on the basis of feasibility studies. The main indicators used in the economic evaluation of design options are the cost of construction and installation works, determined by production calculations, the cost of fixed production assets and working capital of construction and installation organizations, construction time and labor intensity of construction and installation activities, as determined by the calendar plan.

The determination of the comparative economic efficiency of options is made by comparing the reduced costs.

Ci + E n Ki = 3 ni → min ; where Ci is the cost of construction and installation works for option i.

Ki - capital investments in fixed production assets and investments in working capital of a construction organization in accordance with version 1. En is the normative coefficient of efficiency of capital investments in construction.

This takes into account the economic effect of reducing the duration of construction and speeding up the commissioning of facilities. In the general case, the effect of accelerating the input of a production object E / B is determined by the formula E / B = E / nF (T1-T2) ;

where E / n is the regulatory efficiency ratio for the industry to which the input object belongs.

F - the cost of production assets, early entered into action ;.

T 1 and T2 - Accordingly, the actual and regulatory construction time

In the development of the POS and the outage used standard design documentation for the organization of construction and the production of construction and installation works:

- flow charts and schemes for the production of certain types of work;

- schemes of complex mechanization;

- work process maps

- drawings of mechanized installations, means of small-scale mechanization and inventory devices;

- drawings of inventory buildings and structures for construction sites;

- standards of PIC and CPD, methodical manuals.
