• type of reconstruction and scope of future works;
  
• purpose, design features and building material;
  
• necessary consumables (building and decoration);
  
• the need for the use of special machinery and equipment, the level of qualification of construction workers.

When calculating the costs of reconstruction according to the HESN-2001 collections, coefficients that increase the norms of labor costs and the use of special construction equipment are usually applied. This refers to the preparation of estimates for the implementation of the entire complex of works on the reconstruction of objects of any purpose.

If the reconstruction involves the dismantling of structures and the demolition of some buildings, part of the obtained materials or products can be used a second time. In such cases, local estimated calculations tentatively include return amounts that reduce the amount of funding, but are added to calculations for completed works.

The cost of returned materials is calculated based on basic prices in individual rates and other standards.

The cost of transporting such materials and structures to the place of further storage and bringing them to the condition necessary for use is borne by the customer.

Knowing all the necessary intricacies of the application of standards and estimates when calculating estimates for reconstruction will help determine its future cost, monitor the performance of contractors and rationally use own funds.

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.
