It is no secret that estimates for topographic and geodetic work are difficult for non-specialists to understand. And since the respected Customer’s staff does not always include economists familiar with geodetic production, sometimes difficulties arise in determining the actual cost of the planned work.

We decided to make this task easier. Make your own estimate! To do this, download the most suitable template, calculate and indicate the volume of planned work, indicate the categories of complexity, and the estimate is ready!

These templates can be useful in the process of requesting quotes and when conducting competitions by both public and commercial organizations.

In recent years, a rather unsightly phenomenon has become common when potential contractors, in order to get the desired object, drop the price bar to an unacceptable level. Then, after kickbacks and division of advances, they remember with some surprise - after all, there is work to be done! and are looking for subcontractors who are ready to do the impossible for meager money. Such strikebreaking does no one any honor and hurts the quality of the work performed.

To create estimate templates we used:

1. GUIDELINE OF BASIC PRICES FOR ENGINEERING SURVEYS FOR CONSTRUCTION.
ENGINEERING AND GEODESIC SURVEYS
Approved and put into effect by Decree of the State Construction Committee of Russia No. 213 of December 23, 2003.
It quite adequately reflects the real costs of topographic and geodetic work.

2. DIRECTORY OF BASIC PRICES FOR ENGINEERING SURVEYS FOR CONSTRUCTION.
ENGINEERING AND GEODESIC SURVEYS DURING THE CONSTRUCTION AND OPERATION OF BUILDINGS AND STRUCTURES
RECOMMENDED by the State Construction Committee of the Ministry of Regional Development of the Russian Federation by letter dated May 24, 2006 No. SK-1976/02.

Of course, finance is a delicate matter, and the calculations presented here are not the ultimate truth. However, if the price of a potential applicant differs noticeably (by 20-30 percent in any direction) from what we recommend, there is a reason to delve into more detail and consult, for example, with local architectural authorities. This will allow you to avoid unreasonable costs or protect you from poor-quality order execution. An exception may be the case when you do not need to obtain Permits to carry out work, the Conditional System of Coordinates and Elevations will suit you, and based on the topoplan created in this way, projects that require approvals and approvals in the prescribed manner will not be developed. Then you can safely drop the price by 2-3 times and look for a surveyor who is ready, in his free time from his main job, to do unnecessary work for a bare salary, not burdened by the need to purchase instruments and tools, rent an office and maintain accounting, technical maintenance, quality control and pay taxes. It is quite possible that the quality of the work performed by him will be excellent and will satisfy your requirements.

The section will be updated. We are interested in unifying pricing in the industry, and if professionals with their own opinions come here, write! We'll discuss it and perhaps make adjustments.

The issue of saving money is relevant at any time. When we receive a document for payment, we unconditionally believe what is written. But in every bill or estimate that is correctly drawn up at first glance, there may be a “pitfall” or a process, the need for which is very much in question.

Articles from our “Applied Geodesy” series gave you a general idea of ​​the industry and the work performed. You can do some things yourself, but most processes should be left to specialists. It is the issue of reading and checking estimates for geodetic work that will be covered in this article.

Where to start

The basis of any work is the technical specification. It is in it that you and the contractor specify not only the deadlines for completing the work and the responsibilities of the parties, but also indicate additional requirements, which will then be included in the estimate. And here we need to decide - why do we need such work?

You need a project to build a residential building and connect it to city communications. In this case, the work is performed in the state system of coordinates and heights, undergoing a number of necessary approvals. Here you cannot do without a licensed specialist or company, and the contract and estimate will become a supporting document when resolving controversial issues.

You want to do a site layout or alignment for the construction of a light structure. You can do this work yourself by studying the articles in our series, or by inviting a specialist directly, bypassing the bureaucratic red tape. Filming can be carried out in a conventional coordinate system, and the resulting result will meet all legal requirements no worse than official work.

When ordering work, you need to study the pricing in your region. Initial data for drawing up estimates:

• location
• purpose of work
• shooting area
• due date

Let’s take an estimate template as an example and try to figure out what we can save on and what processes we don’t need at all.

1. Collection of data about the topographic basis

Any work begins with getting to know the object. The specialist needs to understand where the survey area is located, which nearest points of the state geodetic network should be used, what is the estimated distance from the enterprise base to the object, and other data. If you have several plots, the estimate should accordingly include the required number of objects. In the case when you have two survey sites, the distance between them is 250 meters, and the estimate says “1 object,” this means that the 250 meters between the sites that you don’t need are included in the cost of the work.

The cost of work is influenced by a coefficient that takes into account the density of the soil into which the point will be attached:

• light soil without coating
• asphalt, medium hard soil
• concrete covering

2. Production and laying of geodetic signs

When laying a theodolite traverse, competent specialists secure survey points (SS) and work points. It is likely that after the survey is completed, you will need to perform a number of other works on the site, namely, setting out boundaries or as-built survey of communications. To do this, the contractor will again have to lay a theodolite traverse, which will undoubtedly be reflected in the final cost of the work.

So if you have this item in the initial estimate, and after a couple of months it is included in the estimate again, hand the contractor a shovel and offer to find the items for which you have already paid money. The shelf life of wooden stakes is 3 months, and metal tubes or dowels - until the metal is destroyed. As you understand, if the destruction of the items was your fault, they will be bookmarked again, but at your expense.

3. Creating a shooting justification

To survey the territory, the contractor needs to lay a theodolite traverse or use the capabilities of satellite geodesy. And at this stage you need to be very careful, especially in the case of GPS. Unobtrusively ask the performer how old is his instrument this year? If the company owns a modern GPS that allows you to receive the coordinates of points in real time, everything is great. If the instrument is 10 years old, and the survey area is built up and surrounded by tall trees, measurement errors are possible, which can appear at the most inopportune moment after the work has been completed.

The number of starting points according to the regulatory documents from which the survey justification will be created must be at least 3, two GPS points are allowed, one initial, the second - control, but if there are more or less of them in the estimate, it is worth asking the designer a question.

If your site is surrounded by tall buildings, it makes sense to use the methods of “classical” geodesy - ask the contractor to work with an electronic total station from polygonometry points.

Let's look at the most typical cases using examples:

a) “Hanging” theodolite traverse.

The most unreliable method of shooting, in which it is difficult to control the obtained values. Here “PP 1 and 2” are the starting points of polygonometry, “vis.1” is the hanging point, the lines show the measurement directions. It is allowed to lay no more than two such points. If the contractor has included in the estimate the survey of two starting points, ask if he is going to work from a move that is literally “hanging in the air”?

b) Closed theodolite traverse.

As can be seen from the schematic diagram, in this case the contractor controls the obtained values, which allows him to be confident in the quality of the work performed. Another option for a move with control involves the use of four points with known coordinates:

As you understand, ideally the performer should use at least two starting points, and preferably three or four. If the estimate states otherwise, there may be cheating or incompetence of the contractor.

4. Creation/updating of engineering topographic plans

These two processes are interrelated, but you only have to pay for one of them.

Creation is shooting a territory from scratch. Suitable for new properties, i.e. those that have been significantly rebuilt, or that were filmed ten years ago. In general, topographic survey is relevant for a year. During this time, changes could have occurred, for which it would be enough to update the engineering topographic plans. The contractor is provided with the original topographic survey from a year ago, onto which he applies the difference in measurements using an instrumental method. If you provided the material, or the contractor has it, and the estimate includes “creation of engineering topographic plans,” it makes sense to suggest that the contractor simply update the existing survey. Accordingly, the price for this type of work will be much lower.

The cost of work is affected by the congestion of the area. The simplest option is an undeveloped plot outside the populated area. From two points determined by GPS observations, all the work can be done. A built-up area implies an increase in the number of filming points, and an industrial site is generally an object of increased danger. Constantly moving machines and mechanisms do not contribute to fruitful work; it is possible to destroy survey points and create obstacles for measurements.

5. Plan-height reference of points

The principle applies here: “the more we rent, the better,” but up to a certain point. The standards determine the number of points per survey area plus places that fall out of the overall picture. This indicator cannot be predicted, but you should know that for an undeveloped area, 8 survey points per square of 50x50 meters plus places where the relief changes are sufficient. Usually this serves as a place to “adjust” the estimated cost of work to the needs of the customer, but in any case, it is necessary to know the standards.

6. As-built survey of utilities

This term refers to filming already laid networks. If this indicator was already included in the initial cost of the work, there is no need to order a topographic survey separately to commission the facility.

Here it is necessary to note a number of points that affect the cost of work. Ideally, all communications should have a binding passport, copies of which are deposited with the architectural authority, the customer, and remain with the contractor. In practice, it is not possible to figure out where the communication passes without drilling control holes in the ground, called “holes”.

One solution to the problem is to use a locator. This device structurally consists of two parts: a generator, which is connected to the required cable core or pipe, and a receiver, which picks up the generated signal under the thickness of the earth.

At this stage of work, there is no need to save money - the communication link passport does not always reflect the real situation. Do not forget that damage to the main pipe entails various types of liability, so you should not trust materials from previous years’ filming. Order instrumental monitoring of underground networks so that you can be sure that you will not leave an entire neighborhood without water or gas.

7. Office work

This tricky term means processing the received values. Plans of the area, underground and above-ground structures are drawn up, profiles are drawn and a catalog of coordinates is generated. It makes sense to pay attention to the end result - what do you get in your hands? The result of the work should be a topoplan on a scale of 1:500 with the drawing of utility networks. If you need an electronic version of a document, ask what program it was created in. The fact is that standard operating system image editors do not always understand the format of data produced by specialized software used in geodesy.

8. Other costs

Everything that is not included in the estimate will be displayed in this section. The main indicator is transportation costs, travel allowances for performers and the complexity factor of the work. The further the enterprise base is from the work site, the higher the overhead costs will be.

The main nuance is buried in this place - who to entrust the shooting to, local specialists or invited “stars”. There can be one criterion - recommendations, personal communication and knowledge gained after reading our article. Where cheaper is not always better, especially when it comes to geodesy issues. You rarely order this kind of work, so it’s worth paying attention to the estimate that they ask you to sign.

If an organization is ready to survey 20 hectares per day with a theodolite, using two points of polygonometry, it is clearly not worth ordering work from such people. Work processes that you do not need indicate an increase in estimates, or even fraud. So remember: forewarned is forearmed.

Question:
What is the procedure for paying for executive and geodetic surveys carried out during the production process and final executive surveys upon commissioning of the facility?
Answer:
In accordance with TKP 45-1.03-26-2006 “Geodetic work in construction. Rules of implementation”, approved by order of the Ministry of Construction and Architecture dated 03.03.2006 No. 60 “In the process of erecting all building structures, when laying utility networks, geodetic control of the accuracy of their geometric parameters must be carried out” (subclause 4.27). According to subclause 4.28 “Geodetic control of the accuracy of geometric parameters provides:
geodetic (instrumental) verification of the dimensions, shape, planned and altitude position of elements, structures and parts of buildings, utility networks and communications for compliance with the requirements of design documentation at the stages of their installation and temporary fastening;
executive geodetic survey of the planned, high-rise and relative to the vertical positions of elements, structures and parts of buildings, permanently fixed upon completion of installation (installation, laying), as well as the actual position of above-ground and underground utility networks and communications.”
At the same time, according to subclause 4.39 “Creation of an internal alignment network of buildings, detailed alignment work, geodetic work during the construction process, geodetic control of the accuracy of the geometric parameters of the building and production
geodetic executive surveys are the responsibility of the contractor (subcontractor).”
All the above works, i.e. geodetic control and executive geodetic surveys are an integral part of production quality control of work performed and the organization’s expenses for these works are covered by the contractor’s overhead costs.
Resolution of the Ministry of Construction and Architecture dated January 16, 2008 No. 1 approved the norms of overhead costs and planned savings for construction and installation organizations performing construction and other special installation work by contract.
In the structure of overhead costs, in section B “Costs for organizing work on construction sites” there is an article “Costs for geodetic work carried out during the production of work”.
The above expenses are included in this item. According to subclause 4.38 of the above TCP, “...Performing final as-built surveys after completion of construction is the responsibility of the customer (investor) and is carried out according to separately developed working documentation.”
Also, according to subclause 11.4.7 “Control geodetic survey of underground utility networks is carried out by the customer (developer) carrying out technical supervision of construction, or, if he does not have specialists, by the forces of another specialized organization.”
(RSTC letter No. 07-2275 dated September 21, 2010)
This is old.
And here is what is stated in the MAiS resolution of December 23, 2011 No. 59
3.6. Expenses for geodetic work carried out during construction and installation work (with the exception of executive survey of utility networks when preparing the object for delivery, paid from the funds provided for these purposes in the consolidated estimate of the cost of construction). This article takes into account the costs of remuneration (with contributions to the social protection fund) of workers engaged in geodetic work, the cost of materials, depreciation, depreciation, costs of all types of repairs and movement of geodetic equipment, tools and instruments, transportation and other expenses for geodetic work, including acceptance of the geodetic basis from design and survey organizations.
