How to read an estimate, so as not to burn. 10 points to be checked

The algorithm checks the estimate for the construction of a country house

Often in order to texts the exchange we see roughly the text of the "Attach to estimate its response." Do you know how to read or burn estimate of the money at the end of construction?

We decided to hold a small educational program on counting costs to discover the pitfalls before you inflate the value of the work several times.

Alexey Bogatyrev, Artist exchanges Forumhouse, helped us to make this checklist.

So, 10 points to be checked in their estimates.

1. The uneven distribution of payment of work performed.

The aim of such a method is used to obtain the full profit from the object to the first stages of work.

For example, the estimates for the construction of the house indicated that 80% of the cost of the work takes the foundation, 15% - a box and 5% - the roof. An unscrupulous contractor can perform under the contract the first phase, to receive 80%, consider whether him to carry out the second stage or not and notify the customer to terminate the contract under any pretext.

Too, but to a lesser extent also applies to the distribution of the cost of materials. Thus, it is necessary to assess the proportionality assessment stages and certain types of work in the estimate.

2. False information regarding the cost and terms of the lease of machinery and equipment.

Especially important for building owners of private houses and cottages.

For example, in terms of volume: in the budget for the development of the excavation for the foundation of an excavator rental period is indicated in three shifts, despite the fact that in this situation, only one shift. The second example in terms of the performance of special equipment: the estimates indicate the price of the concrete pump with characteristics supply 36 meters, given that in this case, concrete is applied with the characteristics of feed 16 meters.

It is necessary to check the estimated data with the characteristics and performance standards of special equipment for your facility.

3. The lack of precision in the estimates of parameters of building materials.

For example, the contract may be stated that for the cladding house shall be established simulation class timber not less than AB, humidity up to 12% in a precisely defined quantity of a certain value. At that time, as an imitation of timber is different from the 16 to 35-mm. standard thickness. Found imitation lumber produced TU, up to 14 mm. Moreover, the thinner that in this case, building material, the worse its performance. The cost of simulating beam thicknesses significantly different.

The customer need, matching estimates require the most complete description of the delivered building material.

4. The lack of technology in the estimate required materials.

For example, the customer, to provide the most competitive deals can make an estimate for the construction of a frame house, excluding vapor barrier materials. Since the cost of quality vapor barrier materials is significant, the customer receives a supposedly more favorable cost proposal.

In the best case, the customer in the process of work will explain the possibility of work with or without a vapor barrier and offer to purchase it. In the worst case - to perform the work without the use of vapor barrier materials.

It is necessary to check for the technologically required materials in the estimate.

5. A general indication of the estimate / contract that supplies paid for by the customer, possibly indicating only their specifications.

Consumables - these are the things that will come into disrepair, they will be expended or disposed of after closure of the object (LBM wheels, for the screwdriver bits, drills, brushes, rollers, lubricants for chain saws or compactors etc.).

Organize the control over the expenditure and the preservation of such items is not easy even to construction companies. A private developer to control your contractor even harder. At best supplies will break down uncontrollably and lost. In the worst - they will steal or provide forged checks. Amount for supplies on a large object can be obtained very significant.

Establishments should be required to estimate a fixed amount of consumables.

6. The absence of quantitative estimates describing the operation cycles.

For example, the mass dyeing technology involves painting surfaces in two layers. Counting in the budget painting in one layer, or indicating the number of paint layers, the contractor gives the customer a better cost proposal. However, when the customer sees the result and it does not suit him, the contractor offers to perform one more painting cycle for an additional cost.

This item also includes additional material costs. It is necessary to check the estimates for work involving cyclical.

7. The absence in the budget process required technologically.

For example, the performance of plaster works, measured at the estimate in an understandable and acceptable to the customer's cost, can not be included priming. Thus, in the best case, the contractor will put the customer account for additional work not specified in the contract / estimate. In the worst case, plastering is carried out without prior priming.

The estimate should be all kinds of work. Or mark (in our example - with "priming").

Must be considered in the study estimates all technological milestones.

8. Incorrect specification of the amount of work in the estimate.

For example, a contractor by examining job customer for painting walls and ceilings, determines the estimate total paintable 110 m² indicating unit prices per m² at real volume 220 m². The contractor thus obtains competitive advantage through dumping costs. However, in the process of execution of works, area obmeryaetsya upon the customer and extra expense is exposed, based on the unit price (m²).

Customer must check volumes in the process of drawing up technical specifications and check the estimated volume of the real.

9. In the absence of estimates of associated activities.

Directly construction work is accompanied by a series of works (unloading, transfer materials and m. P.).

For example, when laying the paving stones on the blind area around the house, the customer can get an invoice for extra work Materials on the transfer, provided that the paving stones in this case will be discharged, as a rule, in one place.

In the study of the estimates should be required to work on unloading were opened in the estimate, for example, as a percentage of the cost of building materials.

10. Wrong number of building materials in the cost estimate.

Two variants of deception of the customer:

The first example: the estimates indicate an inflated number of building materials. In this case building materials can as nedopostavit, receiving the difference as profit, and put in full and take in the course of work on another building project.

The second example: the estimates indicate an underestimated number of building materials. This case is dangerous for customers seeking the best value. The customer selects a contractor, focusing on attractively low cost. During the work it turns out that building materials are not enough. The customer has to pay for the purchase and delivery of building materials in addition. It is necessary to check the estimated amount of building materials with the real object.
