As a rule, those who use ready-made estimate documentation in their work notice such things, but those who draw it up do not notice. It is very bad when such moments are clarified already in the process of execution of the contract, when it remains only to state the fact of budget cuts.

It is quite easy to detect errors in estimates if they are small – on 3-5 sheets, and it is almost impossible to immediately notice them if the estimate exceeds 50, 100 or 500 pages.

However, there are benefits to be gained from this situation as well. Since funds have already been allocated for construction work, especially if the object is budgetary, the Customer can go to a meeting and spend the saved funds on other work that is necessary or on the purchase of any equipment with its installation, within the freed amount of within the framework of the contract already concluded with you, if it does not contain any prohibitions on this. As a rule, the amount of changes under government contracts cannot exceed 10% of the estimated cost.

The second group of mistakes is when they forget to accidentally add some types of work to the estimate. Sometimes such errors violate the technological sequence of work as a whole, which can also lead to losses.

Examples:

We had a facility where work was to be done to strengthen the wall by installing buttresses. Their technological sequence was as follows: earthworks (clearing the work site from the ground, digging pits with an excavator and manually to a depth of 2.5 m), laying footings, installing metal frames and formwork, pouring them with concrete, backfilling pits, compacting soil. So, in the estimate, the very initial earthworks in the amount of approximately 300 cubic meters were completely absent .

You must mount any equipment in the building. But the dimensions of this equipment exceed any maximum openings in the walls; accordingly, it may be physically impossible to bring this equipment inside without temporarily dismantling sections of the walls to increase the openings in them. Not every designer or estimator can foresee such things. Therefore, inspect the place of work before performing work or concluding a contract.

The worst thing is when you have already appointed people, hired equipment and started work, and only then found out everything, because the customer, especially if it is a state customer, may simply not have extra money that he can allocate to complete the data works and all attempts to humanly resolve this issue may lead nowhere . Sue him or incur losses, but do the work, or terminate the contract – this decision is up to you.

In any case, remember that all hidden work must be recorded in acts, and if you completed work today that was not included in the estimate, just so as not to stop all construction or some part of it, then the absence of acts of hidden work, protocols for considering these commission issues, etc. will complicate your situation if you decide to prove your case in court or in any other way to resolve this issue.

There are also other situations. I was once asked to mount a turnkey door. I mounted and forgot about this business until the customer called me and asked “Where are the slopes?”. In his opinion, slopes were included in the concept of “turnkey”, but in my opinion , if they were not mentioned in principle, they were not in the “turnkey”, but there was only a door, its delivery and installation. Speak every little thing, and better reflect in the contracts.

In order to avoid misunderstandings, so that both the contractor and the customer clearly understand what is included in the cost of work and what is not – i.e. whether materials are included in the cost of work, when drawing up an estimate, it is necessary to accurately describe the materials used and their quantity. If you received an estimate for consideration, deal with this issue paramountly.

So, there are two types of estimated or contractual prices:

1. Prices without the cost of materials;

2. Prices including the cost of materials.

Most often, prices that include the cost of materials are used in state estimates, these are the so-called FER (federal) or TER (territorial) unit prices. They facilitate the accounting of expenses of budgetary organizations, budget planning, and are also adjusted for inflation, etc.

Let's compare two types of rates:

Prices without the cost of materials:

FER15-01-090-03 (approved by the Order of the Ministry of Construction of Russia dated December 30, 2016 No. 1039 / pr ) – “Arrangement of ventilated facades with porcelain tile cladding: with a heat-insulating layer”.

FER11-01-027-02 – “Installation of cement mortar coatings from ceramic tiles for multi-color floors”.

Prices including the cost of materials:

FER15-04-012-02 – "Painting of facades from scaffolding with surface preparation: organosilicon".
