- installation and assembly of equipment components, if the transport position of the machine implies their dismantling;
- connecting communications (electricity, compressed air, water, etc.) using customer materials (electrical cable, fittings, hoses, etc.);
- setup and commissioning of equipment;
- checking the functionality of the equipment at idle and in operating mode, checking that the performance characteristics comply with the declared ones;
- production of test samples of parts using the functions of the equipment (in some cases it is possible to manufacture parts according to drawings and customer requirements);
- consultation and instruction of customer personnel on issues related to the operation and maintenance of equipment.
What is the difference between commissioning and installation supervision work?
In order to understand this issue, it is necessary to define the concept of commissioning. Unlike installation supervision, it is found in SNiP 3.05.05-84: “Commissioning works include a set of works performed during the preparation and conduct of individual tests and comprehensive testing of equipment.” It follows from this that, apart from the difference in the name, there are no other differences in the general understanding of the wording. With one exception: since the activities carried out as part of the installation supervision work are not regulated, when concluding a contract there is room for creativity, i.e. the ability to determine activities and conditions for their implementation that fully satisfy the customer’s requirements. Why is installation supervision necessary?
High-quality installation supervision work can radically reduce the risk of errors during installation, commissioning and further operation of equipment, identify possible problems even before putting the equipment into operation, which ultimately helps to increase the reliability of equipment operation and, as a result, eliminates equipment downtime. Supervision of installation work carried out by authorized organizations eliminates many organizational and technical difficulties that inevitably arise when installing new equipment unfamiliar to personnel.Who should perform installation supervision work?
When working with customers, most equipment suppliers highly recommend execution of installation supervision works by authorized specialists. An exception may be customers and partners whose specialists are well familiar with the supplied equipment, have been servicing it for a long time, or have undergone special training. It is necessary to take into account that when performing work on its own, the customer assumes all risks associated with both its implementation and further operation of the equipment.How to plan installation supervision work and prepare for it?
There are two options for equipment delivery:- installation supervision work is included in the cost of the equipment;
- installation supervision work is paid for and performed under a separate contract.
- dimensions, weight of equipment;
- method of installation and installation of equipment in place;
- used tool, equipment;
- technical fluids used;
- necessary communications;
- requirements for operating personnel.

Supervised installation work is the installation of equipment directly by the supplier’s managers. The working personnel are provided by the buyer, and the control of the main components is carried out by specialists from the performing company.
What does the supplier guarantee?
The equipment supply company undertakes to provide full support for the ongoing project. Based on the results of the completed activities, the buyer accepts the installations that are already fully prepared for launch into production.
Installation supervision works are activities during which the supplier assumes certain responsibilities. Within his competence:
- conclude a contract for installation supervision;
- resolve organizational issues of installation;
- provide technical preparation of the project and its implementation;
- supervise employees;
- supply all equipment and additional spare parts if necessary;
- if the work is carried out by the supplier’s specialists, his responsibilities include delivery of a fully working installation;
- bring the equipment to the declared capacity;
- complete the installation by drawing up a report on the work done and acceptance of the installation by the customer.
What does the supplier do?
Installation supervision is activities to supervise each individual part of the installation procedure of purchased equipment. Under the supervision of specialists, the customer’s employees perform the entire installation complex. They adjust and adjust the main parameters, adjusting them to the appropriate performance.
Upon completion, the batch of suitable products specified in the contract is delivered. Installation supervision is the optimal choice for installing new technological solutions in existing production. The customer is relieved of routine duties. Often it is not possible to look for relevant specialists, who will no longer be needed by the organization after the commissioning of the facility.
The management of the selling company has the most complete experience in the installation of complex technical products. All operations are perfected to the smallest detail, the staff is ready for unforeseen situations and malfunctions. We have our own developments on the organization of work and the sequence of actions performed.
Equipment setup points
The supplier’s responsibilities include supervision of installation and commissioning, including a full cycle of monitoring the functioning of the assembled installation:
- the compliance of the finished product with documentation and drawings is checked;
- parameters of technological operating modes are adjusted;
- the equipment is turned on for the first time;
- trial testing is carried out in an automatic cycle;
- control and verification of the produced trial batch of finished products is carried out;
- The customer's engineers and workers carry out adjustments under the guidance of the equipment supplier's specialists.
Responsibility for the quality of work lies entirely on the shoulders of the supplier. The customer and his specialists are only performers. Any damage caused by improper assembly will be compensated at the expense of the seller. Faulty elements are replaced before the object is delivered.
Documentation
Before starting work, the site is carried out on site. Fully coordinated actions are prescribed in a contract that suits the customer. It includes all items of work, deadlines, in addition, a preliminary cost is specified. Each project is unique and requires careful preparation of documents by specialists.
Project changes are often required due to unforeseen conditions. Adjustments are made immediately and discussed with the customer. The completion of the work is carried out in accordance with the completed documentation (installation supervision certificate). After its signing, the object is handed over, and the buyer of the equipment and services confirms the quality of the work performed.
Pros of hiring a supplier
Often, at critical sites, inexperienced specialists carry out installation supervision work. The identification of priority tasks is carried out incorrectly. The consequence of this approach is equipment downtime and additional costs to correct the situation.
Experienced customer specialists have already encountered problems of this kind and know how to quickly cope with even the most difficult situation. A guarantee is given for the work done, which additionally insures the customer. After all, when the object is delivered on time, then everything goes according to the planned path of business development. This means that the payback from modernizing the line will correspond to the stated indicators.
Miscalculations can be avoided if you entrust the matter to professionals. Each step of the work will be documented. The delivery of the object will take place according to the stated requirements of the customer. Additional changes are possible during installation in agreement with the supplier’s specialists.
Subsequence
The work performed includes the following actions of the performer. Experienced specialists begin their preparation by inspecting the site. The project is analyzed by engineers and its compliance with real conditions is assessed. Based on the results, measuring instruments and technical means are selected for marking the main equipment installation points.
The requirements of GOSTs and other regulatory documents for the selected installation methods and the means used are compared. The qualifications of the customer’s employees, the availability of permits, tolerances for heights, cranes, and electrical work are checked. If the technical equipment does not meet the requirements, it is considered unsuitable for performing work. If they were provided by the customer, they will be returned or replaced with working equipment.
When all the nuances are agreed upon and documented, the actual installation begins. Only after checking the work by the customer’s employees is permission given to turn on individual components first, and then the entire installation. They strive to fine-tune operating modes, and train process personnel and technical services. The buyer is provided with documentation, applications, a list of spare parts with nomenclature for ordering.

Any enterprise is faced with the need to install new equipment or replace outdated equipment. These can be both main production lines and auxiliary systems, for example, ventilation or water supply. For normal operation of the equipment, installation must be carried out by qualified personnel.
Manufacturers of various lines and systems, as a rule, offer their services for installation, connection, test run of equipment, training of adjusters or other specialists. The entire list of services is specified in the contract. As for air exchange lines, you can order the installation of engineering ventilation systems on the website http://tdhvac.ru/. Installation of equipment is carried out through supervision of installation and commissioning, depending on the wishes of the customer.
What is installation supervision
With this type of work, installation and installation of equipment is carried out by customer specialists or contractors under the organizational and technical guidance and supervision of the supplier. The work is accompanied by remote consultation and on-site visit of a specialist. The equipment is launched and tested by the supplier. The concept of installation supervision is not regulated by any standards.
Commissioning works
This type of work differs from installation supervision in that the installation and commissioning of the equipment is carried out by the supplier. Commissioning works are regulated by SNiP 3.05.05-84. In essence, installation supervision and commissioning work involve performing the same operations by different performers. In both cases, safety regulations must be strictly observed.
Ordering and installation of equipment
When drawing up a contract for the installation of equipment, the specification, quantity and quality of devices, delivery dates, installation work and launch are prescribed. Specialists from both organizations agree on the entire technological scheme, select a location for installation and a plan for the arrangement of equipment. After delivery, the contents are checked. The supplier organization provides the necessary technical documentation for the installation, operation and maintenance of lines, systems or installations. Assembly is carried out strictly in accordance with technical drawings.
Start-up and commissioning of equipment, finishing work
After installation, the equipment is connected to the power supply and pre-started. In accordance with the technical specifications for both individual units and systems as a whole, the necessary operating modes are adjusted. By agreement, the supplier organization trains specialists whose work is related to the operation and maintenance of equipment and prepares working documentation. When all the terms of the contract are met, a certificate of completion of work is drawn up and signed.
Carrying out installation supervision or commissioning work by qualified specialists is the key to uninterrupted operation of the equipment in accordance with technical specifications, as well as a guarantee of timely service in case of problems.
