NDP: decoding (construction). Explanation of design and survey, construction and start activities,

Any specialist in the field of construction should know what is the NDP. Decoding of this abbreviation, as well as several others, will be presented below.

Design and survey work

The abbreviation of three letters - PIR - stands for a complex of works on engineering surveys, preparation of projects, development of economic and technical justifications and working documentation, drawing up of estimate documentation for construction (it may be new or involve reconstruction and expansion). Depending on what conditions are stipulated in the contract, these works can be carried out either by the general designer, or by the design customer. Have you thought about what is the NDP? The decoding of the abbreviation is presented in the article. Engineering surveys are conducted to obtain data on the natural conditions of the territory where it is planned to build. The information obtained is an important part of the data for the project. Engineering surveys are carried out by specialized organizations that have licenses. In some cases, structural units and organizations can act as executors, namely, survey departments. You are faced with the concept of "Poland"? The decoding of this abbreviation is presented below.

Depending on the complexity and size of the projected facility, engineering and geological surveys are carried out by one or more organizations. In the second case, one company acts as a general contractor, while the others perform the functions of subcontracting. If we consider all cases, then in most of them the whole amount of work for a particular construction is carried out by one organization. If you are interested in deciphering the design, design, construction, commissioning, it is important to read the information below.

If we talk about the first abbreviation, then during the period of economic reforms, most of the survey organizations in Russia became joint-stock companies. Some were divided into small enterprises. An interesting fact is that many of them have not changed their names, leaving the abbreviation TISIZ, which stands for "trust engineering and construction surveys."

Research tasks

The initial data and the requirements for the results are set in the task, which is issued by the customer or the project organization. According to SNIP 11.02-96, five types of surveys can be distinguished. In addition to these five types, 10 types of works can be attributed to engineering surveys, which are of an auxiliary nature. This includes research of soils, geotechnical control, risk assessment and risks from man-caused and natural processes. This list is not complete.

What is SMR?

SMR and Poland, the decipherment of which will be known to you after reading the article, are related to the field of construction. Construction and installation work involves a set of activities that are carried out on the construction site. As a final result of such works is a ready construction or a building put into operation. Installation work involves a process that consists of several steps, among them - preparation, basic work, auxiliary and transport. At the first stage, the design and estimate documentation is reviewed and reviewed. If it is not available, then the relevant companies are engaged in its development. These documents include agreed, and after approved project, estimates and specifications, as well as an explanatory note. Based on the RMC, the calculation of the cost of materials and all work is carried out, equipment is proposed, the terms of the construction are stipulated.

The second stage of construction and installation works

The next step is organizational and technical training. In the process, a contract is signed, a schedule, financing is specified, and the delivery time of equipment is determined. It is important to take into account the seasonal factor, which causes the works to be performed by the beginning of the period.

Step-by-step construction

The process of construction and installation works involves rough manipulation, namely laying of the trunk, installation of equipment, testing, etc., which can restrain the beginning of subsequent work. The next stage is finishing works, such as mounting sensors, drives and other things. Installation works are carried out completely in accordance with technical acts, technology and norms. Specialists carry out quality control at each stage, make necessary documentation. At the fourth stage, individual tests are carried out, the installed systems are analyzed.

Description of commissioning works

If you are interested in the abbreviation PPR, the decipherment of this abbreviation and its meaning is given below. Commissioning is a whole complex of manipulations, which involves checking, subsequent setting up and final testing of electrical equipment to ensure the mode and parameters that were set by the project. In this case, the expert is guided by the sanitary norms and rules. It is important to observe four stages, the first of which is preparatory, the second is the commissioning work in conjunction with the wiring, while the third is the individual testing of equipment. The final stage involves testing the equipment. If you are thinking about what the NDP is, deciphering the construction of the abbreviation will allow you to understand what works are done when it is necessary to start and set up electrical equipment.

Requirements for NDP

At the second stage, the customer provides power supply in the work area. If necessary, a pre-installation audit is performed. Experts replace defective equipment and supply the missing. At this stage, it is important to eliminate the existing defects, trying to identify them in the production process. Based on the results of the tests, a protocol is drawn up, which is transferred to the customer.

The main stages of the NDP

The procedure for drawing up estimates for the NDP is determined by the provider of services. While the safety requirements for commissioning and electrical installation work are provided by the manager of the latter. If commissioning works are performed on a combined schedule on different functional groups and devices, such manipulations are coordinated with the managers of electrical installation works. The ratio of NDP and SMR should be taken into account by the service provider.

Instead of concluding

When the third stage is carried out, the equipment is serviced by the customer, which ensures the placement of personnel, disassembly and assembly of schemes. At the last stage, the PNR for the interaction of electrical equipment and electrical systems in different modes is performed.

These manipulations involve communication, adjustment and adjustment of the parameters and characteristics of devices, as well as functional groups, to provide specified operating modes. The electrical installation is tested both at idle and under load, and without fail in all possible modes.
