Any specialist in the field of construction should know what the NDP is. The decoding of this abbreviation, as well as several others, will be presented below.
Design and survey work
The three-letter abbreviation - PIR - refers to a set of works on engineering surveys, project preparation, development of economic and technical justifications and working documentation, preparation of budget documentation for construction (it may be new or involve reconstruction, as well as expansion). Depending on what conditions are specified in the contract, these works can be carried out either by the general designer, or by the customer of the design. Have you thought about what the NDP is? The abbreviation is presented in the article. Engineering surveys are conducted to obtain data on the natural conditions of the territory where construction is supposed to be carried out. The information received is an important part of the data for the project. Engineering surveys are carried out by specialized organizations that are licensed. In some cases, structural units and organizations, namely, survey departments, can play the role of performers. Have you come across the concept of "NDP"? The interpretation of this abbreviation is presented below.
Depending on the complexity and size of the projected object, geotechnical surveys are carried out by one or several organizations. In the second case, one company acts as a general contractor, while the rest serve as subcontracts. If we consider all cases, then in most of them the entire scope of work for a particular construction is carried out by one organization. If you are interested in decoding PIR, construction, installation, and commissioning, it is important to read the information presented below.
If we talk about the first abbreviation, then during the period of economic reform, 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 Survey."
Survey Tasks
The initial data and requirements for the results are set in the task, which is issued by the customer or design organization. According to SNiP 11.02-96, five types of surveys can be distinguished. In addition to these five types, 10 types of works that are auxiliary in nature can be attributed to engineering surveys. These include soil research, geotechnical control, risk and hazard assessment from technological and natural processes. This list is not complete.
What is SMR?
Construction and installation work and commissioning, the decoding of which will be known to you after reading the article, belong to the field of construction. Construction and installation work involves a set of activities that are carried out at the construction site. The final result of such work is the finished construction or the 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, there is a study and consideration of design estimates. If it is absent, then the corresponding companies are engaged in its development. These documents include the approved, and after the approved draft, estimates and specifications, as well as an explanatory note. Based on construction and installation works, the cost of materials and all work is calculated, equipment is offered, and the terms for the implementation of construction are specified.
The second stage of construction works
The next step is organizational and technical preparation. In the process of this, an agreement is signed, a schedule is agreed upon, financing, and delivery times for equipment are determined. At the same time, it is important to take into account the seasonal factor, which determines the completion of work by the beginning of the period.
Phase of construction and installation work
The process of construction and installation work itself involves rough manipulations, namely laying the trunk, installing equipment, testing and so on, which can delay the start of subsequent work. The next stage is finishing work, such as: installation of sensors, actuators and other things. Installation work is carried out in full accordance with technical acts, technology and standards. Specialists carry out quality control at each stage, draw up the necessary documentation. At the fourth stage, individual tests are carried out, installed systems are analyzed.
Description of commissioning
If you are interested in the abbreviation NDP, the decryption of this abbreviation and its meaning is given below. Commissioning is a whole range of manipulations, which involves checking, subsequent adjustment and final testing of electrical equipment to ensure the mode and parameters that were set by the project. In this case, the specialist is guided by sanitary norms and rules. It is important to observe four stages, the first of which is preparatory, the second is carried out commissioning in conjunction with the electrical installation, while the third is an individual test of equipment. The final stage involves the testing of equipment. If you are thinking about what the NDP is, decoding in the construction of the abbreviation will allow you to understand what work is done when you need to start and commission electrical equipment.
Requirements for the NDP
At the second stage, the customer provides electricity in the territory of the work. If necessary, a pre-installation audit is carried out. Specialists replace defective equipment and supply the missing. At this stage, it is important to eliminate existing defects, trying to identify them in the production process. Based on the test results, a protocol is compiled and transmitted to the customer.
The main stages of the NDP
The procedure for preparing estimates for the NDP is determined by the service provider. Whereas safety requirements during commissioning and electrical installation work are provided by the head of the latter. If commissioning is carried out according to a combined schedule on different functional groups and devices, such manipulations are coordinated with the managers of electrical work. The ratio of NDP and construction and installation work must be taken into account by the service provider.
Instead of a conclusion
When the third stage is carried out, equipment maintenance is carried out by the customer, ensuring the placement of personnel, disassembly and assembly of circuits. At the last stage, a panorama of the interaction of electrical equipment and electrical systems in different modes is performed.
These manipulations involve the provision of communication, configuration and adjustment of parameters and characteristics of devices, as well as functional groups to ensure specified operating modes. The electrical installation is tested both at idle and under load, and without fail in all possible modes.
