Installation supervision

Supervised installation work - work to control the quality of installation work, adjustment and commissioning of the Goods in accordance with the working documentation, taking into account the requirements of manufacturers, technical conditions or instructions for the operation of the Goods;

When performing installation supervision works, JSC Novamash performs the following works:

• control over compliance with design decisions;
• development of schedules for construction and installation and / or installation works;
• control over compliance with the deadlines and quality of installation work, the requirements of regulatory documents;
• checking the availability of documents certifying the quality of structures, products, materials used in construction (passports, certificates, laboratory test results, etc.);
• control over the elimination of identified defects by the installation organization;
• intermediate acceptance of the critical units of the Goods together with the representatives of the Buyer;
• registration of documentation for conservation or temporary suspension of installation work;
• phased delivery of projects for further installation work;
• other types of work necessary to ensure the achievement of the goals of installation supervision.

The end of the installation supervision work is the proper installation of the Goods or the Project in accordance with the design documentation.

Commissioning works

Commissioning works - works that must be performed after the completion of installation or construction and installation works, including checking, adjusting and testing the Goods in order to ensure the parameters and modes specified by the technical documentation. The purpose of commissioning is to prepare the Goods for operation with the parameters specified in the Annexes to the Agreement.

When carrying out commissioning works, JSC Novamash undertakes to perform the following:

• develop (on the basis of the design and operational documentation of manufacturers) the Program of individual and complex testing of the Goods and the Detailed schedule & nbsp; and a project for the production of commissioning, including incl. and safety measures;
• transfer the comments to the Buyer (if any) & nbsp; on the project, identified in the process of developing the Program of individual and complex testing of the Goods, the Detailed schedule and the project for the production of commissioning;
• prepare a fleet of measuring equipment, test equipment and fixtures;
• carry out commissioning works combined with electrical installation works, with voltage supply according to a temporary scheme in accordance with the current safety regulations, with full readiness of construction and installation works;
• perform a check of the installed electrical equipment with voltage supply from test circuits to individual devices and functional groups;
• prior to the start of individual tests, transfer to the Buyer in one copy the protocols for testing electrical equipment with increased voltage, grounding and protection settings, as well as make changes to one copy of the circuit diagrams of power supply facilities that are switched on under voltage;
• if necessary after agreement with the Buyer  perform a preliminary check and adjustment of individual electrical equipment devices, functional groups and control systems outside the installation area in order to reduce the time for putting the Goods into operation;
• perform individual tests of the Goods;
• adjust the parameters and characteristics of the Goods, & nbsp; testing of control, protection and signaling circuits, as well as electrical equipment on  idling to prepare for individual testing of process equipment;
• ensure the deployment of operational personnel, assembly and disassembly of electrical circuits, as well as carry out technical supervision of the state of electrical and technological equipment;
• after completion of individual testing of the Equipment, perform individual testing of process equipment;
• after carrying out individual tests of the Goods, transfer to the Buyer the executive documentation, incl. protocols for testing electrical equipment with increased voltage, checking grounding and grounding devices, as well as executive schematic & nbsp; technological and electrical circuits necessary for the operation of the Goods;
• after completion of work, issue together with the Buyer an act of technical readiness of the Goods for comprehensive testing;
• carry out a comprehensive testing of the Equipment according to the approved Program;
• perform work on setting up the interaction of technological and electrical circuits and systems in various modes, which include:
  1. providing interconnections, adjusting and setting the characteristics and parameters of individual devices and functional groups of the installation in order to provide it with the specified operating modes;
  2. testing the unit in full scheme at idle and under load in all modes of operation in order to prepare for a comprehensive testing of process equipment;
• carry out other types of work necessary to ensure & nbsp; achievement of the goals of commissioning.

Commissioning works are considered completed after receipt on the Goods & nbsp; the technical parameters and modes provided for by the project that ensure a stable technological process.
