Services and the development of additional sections not included in the basic design package for gas facilities at the enterprise. At this stage, the environmental protection section is developed, geodetic and geological surveys are conducted, and the “Emergency Response and Mitigation Plan for High-Risk Facilities” (ERMP) is prepared.

Preparation of project documentation. This includes the technical specifications for the LPG project, civil defense engineering measures, an early emergency detection and warning system, the preparation and registration of a declaration for a high-risk facility, an environmental impact assessment (not required if an EIA is available), and, following the project review, the development of design documentation for the “Working Design” stage, etc.

Approval of project documentation. This includes uploading the project to the “Unified State Electronic System for the Construction Sector” portal, reviewing the project, and submitting the project documentation to the client.

Obtaining a permit to begin construction, as well as a certificate of completion. This stage includes the preparation and formalization of technical documentation—the technical design documentation (TDD)—supervision of the construction site by the design organization, and certification of the tank(s) at an expert center.

Obtaining permits for the operation of facilities and other components of the LPG gas supply system. At this stage, the safety data sheet for the potentially hazardous facility is registered with the Insurance Documentation Fund, and a Certificate for a Potentially Hazardous Facility is obtained; the identification of the potentially hazardous facility is approved by the State Labor Service and entered into the registry; and other actions are carried out related to the final stage of designing gas installations for the enterprise (briefly outlined in the list on the gas supply design page).

The final step involves training staff on occupational safety rules in accordance with NPAOP 0.00-1.76-15, “Safety Rules for Gas Supply Systems,” with the client paying the expert organization directly for this service.
