• The direction perpendicular to the intersection;
• Minimum length and depth of laying pipes;

• The most favorable soil conditions;
• The banks and the bottom of the river are not eroded in the place of reclamation.

• Engineering inventions.
• Reconnaissance of the crossing construction area, selection of the route will be created in kind.
• Development and approval of POC and PPR.

• Clarification of the minimum and maximum water levels in the reservoir, the duration of their standing, as well as the width of the mirror at these levels.
• Conducts control measurements of depths according to the design.

Crossing - crossing through ravines, roads (road and railway, including subway lines and tram tracks) and city passages is carried out according to a special project, the methods of laying pipeline crossings through natural and artificial obstacles are determined by the project.

The laying of underground pipelines under roads should be carried out under constant surveying and geodetic control of compliance with the planned and height positions of casings and pipelines.

Passages of water pipes under railways and highways are made in cases (shells).

The transition ensures the safety of traffic during pipeline laying works, protection of the ground surface and road surface from erosion during an accident, and protection of the pipeline from damage under the influence of external loads.

When crossing electrified railways, protection against stray currents must be provided.

The transition project is subject to coordination with local authorities of the Ministry of Communications and the Ministries of Highways and Road Transport.

Company "Gutman Construction" specialists are ready to help at all stages of decision-making, both at the stage of considering the concept and choosing a place (creation) of the duiker or transition device, as well as at the stage of preparing technical tasks for design and necessary searches.

The experience of our specialists allows us to solve the most difficult engineering tasks in the optimal time frame and offer the customer a competitive price for design and research works.

The main difficulties and mistakes
with independent design:

1. Lack of an agreed project of the Sanitary Protection Zone (SZZ)
2. Lack of metering devices and objective (calculated) data on the required productivity.
3. Lack of title deeds to the land.
4. Inaccuracies in the preparation of the Terms of Reference: all the necessary studies were not taken into account, the documents listed above were not taken into account.
5. The justification of the price was performed incorrectly, on the basis of commercial proposals of non-specialized organizations, without taking into account the fulfillment of the requirements of technical conditions, the need for inspection of buildings and structures, etc.
6. Surveys, research, and design are performed by different companies, which causes delays and additional work.

 Decisions from
Company "Gutman Construction":

• We will analyze the existing situation, prepare the Terms of Reference for the SZZ project. If necessary, we will execute the project of SZZ and agree on it.
• We will collect all the necessary data, make calculations and submit it to the customer for consideration. If necessary, we will temporarily install metering devices.
• We will help in the preparation of documentation, if necessary, we will include it in the TOR for design.
• We will analyze the existing situation and prepare the correct technical task.
• We will prepare an estimate for design and exploration works and surveys, based on basic price guides.
• We have considerable experience and qualifications for the organization of a full range of design and search works. Company "Gutman Construction" has SRO permits for both design and exploration work. We are guaranteed to provide a positive conclusion of the examination and support during SMR.
