Design, survey and commissioning work: what is it, why is it necessary and who performs

Krympress reports:

During the construction, reconstruction and operation of facilities-from residential buildings to industrial complexes-two of the most important stages are of key importance: design and survey work (PIR) and commissioning (PRD). These services underlie the security, functionality and efficiency of any object. We will analyze in more detail what includes these types of work Enreg.orgwhen they are required, who are executed and how to choose a reliable contractor.

What are design and survey work

Composition and tasks Pir

Design and survey work is a set of engineering, geodetic, geological, environmental and design measures aimed at preparing design documentation and justification of the construction (or reconstruction) of the facility. Include:

Engineering surveys:

• geodetic (shooting, leveling, determination of the coordinates of the site);
• geological (analysis of soils, aquifers);
• environmental (environmental impact assessment);
• Hydrometeorological and other studies.

Design:

• development of the architectural and constructive part of the project;
• project of engineering networks (power supply, water supply, sewage, ventilation);
• development of estimated documentation;
• Coordination of a project with supervisory authorities.

When design and survey work are needed

Feast is a mandatory stage for:

• new construction of any capital facilities;
• reconstruction, modernization or re -profiling of buildings and structures;
• technical re -equipment of production sites;
• development of plans for improvement or integrated development of the territory;
• Overhaul, if it affects the supporting structures or engineering networks.

What is launching work

The essence and stages of PNR

Launching work is a set of actions performed after the completion of the construction or installation of equipment aimed at putting an object or system into operation. Their task is to ensure the correct and safe operation of all engineering systems.

PNR composition:

1. Checking the compliance of installation to the project.
2. Primary launch of equipment.
3. Setting up operating modes and automatic control systems.
4. Fixation of functioning parameters.
5. Testing and commissioning.
6. Training of customer personnel to work with equipment.

Where start -up work is required

• When commissioning new facilities: residential buildings, business centers, production sites.
• In the reconstruction and modernization of engineering systems.
• When installing or replacing engineering and technological equipment: boilers, pumping stations, ventilation installations, machines, automated lines.
• As part of the safety verification before launch.

Who performs a feast and PNR

PIR specializing companies

Design and survey work is carried out by design organizations that have allowed the SRO (self-regulatory organizations), the staff of specialized specialists and the corresponding technical equipment. Such companies can be highly specialized (for example, only designing internal engineering systems) or provide a turnkey complex services.

The team should have:

• architects;
• Design engineers (OVIK, EOM, VK, SS, etc.);
• Geodesists;
• Ecologists and geologists;
• Estimated specialists.

Contractors of the PNR

Launching work, as a rule, perform:

• construction and installation organizations allowed for such types of work;
• Specialized adjustable enterprises;
• Manufacturers or suppliers of equipment that include PNR in the delivery kit.

PNR performers must have:

• qualified engineering and technical composition;
• experience with specific systems and equipment;
• licenses and tolerances (in some cases — Rostekhnadzor, FSB, Ministry of Industry and Trade, etc.);
• the possibility of testing and drawing up protocols.

How to choose a reliable artist

Criteria for choosing a contractor for a feast

When choosing a company to carry out design and survey work, pay attention to:

• Nnalities of the SRO tolerate — without it, the design of capital construction facilities is illegal.
• Experience and portfolio — the more implemented objects, the higher the examination.
• A comprehensive approach — the presence of all specialists in the state or close cooperation with trusted subcontractors.
• Technical equipment — the availability of modern software (AutoCAD, Revit, Civil 3D, etc.), geodetic devices.
• Reputation — reviews, recommendations, open cases.

How to evaluate the reliability of the Contractor of the PNR

Key factors:

• Specialization and experience in the right industry — for example, not every company that has established ventilation in the office will cope with systems in chemical production.
• Warranties and afternoon escort — it is important that the contractor is ready to eliminate identified problems and help maintaining systems.
• The presence of your own laboratory or access to accredited laboratories for testing.
• Consent to the official submission of work with the execution of acts of the PNP and the provision of all technical documentation.

Pir and PNR as part of the life cycle of an object

Design, survey and commissioning work accompany the object on different stages of his life cycle:

• Construction TEMA → Order PIR for obtaining permission.
• Construction/reconstruction → Attracting designers and refiners.
• Installation of equipment → Order of PNR for its correct setting.
• Operation → Repeated PNR when replacing nodes or accidents, as well as during modernization.

Errors when ignoring the Pir and PNR

• Construction without geology can lead to a subsidence of the foundation.
• Errors in the design of engineering networks — to system accidents and non -working communications.
• The absence of PNR is the reason for the failure of the equipment, violations of safety standards.
• The lack of official delivery of the NCC is the inability to put the object into operation.

According to experts, design, survey and commissioning is the basis of high-quality construction and reliable operation of facilities. They allow you to avoid expensive errors, to ensure the safety and legality of the project. The order of such services requires an attentive approach to the choice of the contractor: from the allowance of SRO and experience to readiness to accompany the object at all stages. With competent implementation, the PIR and the PNR become the key to successful commissioning of any building or structure.
