The basis of engineering preparation of territories should be:

1. Concept of implementation of the investment project and stages of its development.
2. Rules included in the Urban Planning Code of Ukraine.
3. Building norms and rules (SNiPy).

Any construction begins with engineering preparation of the territory:

• construction of roads
• laying of water pipes and drainage (sewage)
• laying cable networks
• gas pipelines
• treatment plant
• water intakes
• water treatment stations and pumping stations
• etc.

That is why the correct organization and technologies of carrying out these and other works related to preparatory works are so important.

It should be noted that both from an organizational and technical point of view, the engineering preparation of territories for development has always been considered and is considered the most difficult and time-consuming process.

The fact is that the engineering preparation of territories — especially in the case of complex development of districts of quarters for the future construction of objects — requires particularly clear, coordinated in time and space actions of all participants of such work. After all, engineering networks are closely technologically interconnected.

Even more important is a well-thought-out plan of action in the engineering preparation of large areas, unfortunately, it should be noted that in many cases there is no such consistency.

• Territory planning project (which must have an engineering component)
• Collection of raw data and development of the engineering training project
• Construction and development of "main" infrastructure facilities
• Construction of main engineering communications

• Engineering preparation of building blocks
• Intra-quarter engineering training
• Bringing engineering networks to specific objects

Even with perfect compliance with all stages of the problem, there are numerous contractors whose coordination practically does not occur, although it would be logical to entrust such coordination to the General Designer.

The main inconsistency arises at the level of Designing engineering preparation of territories, because some of them are occupied only by cable networks, others by water pipes, others by gas, etc. There are very few qualified companies on the market of design organizations that are ready to organize and coordinate the entire complex of project works on engineering preparation of the territory, taking into account the phasing of the implementation of the customer's investment project.

The lack of experience in the implementation of infrastructure projects leads to the adoption of non-rational decisions (acceptable from the point of view of SNiP, etc.), which can limit the possibilities of development and expansion of engineering capacities or significantly increase operating costs, etc.

Failure to properly connect project solutions and actions of individual customers and their contractors during the connection of networks to individual construction sites lead to a significant increase in the price of construction and installation works and disruption of deadlines.

To eliminate these inconsistencies, a single general designer for engineering preparation of the territory should be determined, taking into account the experience of implementing such projects.

Even bigger problems arise during the so-called renovation of already built-up areas, in particular, there it is necessary to reconstruct all engineering communications in a comprehensive and coordinated manner without disrupting the functionality of the main trunk networks.

• 1st stage. Analysis of European experience.
• 2nd stage. Collection and analysis of raw data.
• 3rd stage. A detailed engineering and technical review of the options, separately for each system for each element (object) of the scheme with a detailed review of the main technical factors affecting the main and operational costs. Discrete techno-economic comparison of options. Modeling according to variants of system schemes.
• 4th stage. General scheme of engineering training. Based on the materials of the considered options, matrix models of the considered options are made. Matrix analysis will allow finding optimal balance ratios of costs and results of production and economic activity. Optimization of the schemes obtained at the previous stages of the feasibility study development.

• 5th stage. Final modeling. Modeling of variants of the general scheme of engineering training on the basis of optimal solutions obtained at the previous stages of feasibility study development.
  Modeling and mathematical analysis of the entire system.
• 6th stage. Development of variants of the general system of monitoring, accounting and management of systems.
• 7th stage. Results of technical and economic comparison. Conclusions.

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.
