3. We used more expensive anchors, no one compensated us for the difference in price, again because there is an estimate approved in the budget – please be kind enough to fit into it. This is called “replacement without increasing the value of the contract”. Although the increase in the cost of fasteners was about 20%.
Prevention measures.
1. Extremely vigilantly compare not only the estimate with the project, but also the project with the real object.
2. Be sure to correspond and notify the customer in writing about the identified errors and inconsistencies in the design and estimate documentation, draw up acts for all, including commission inspection acts. In the future, this can help not only to make changes to the project documentation correctly, but also to justify the change in the cost of work.
3. Carefully read the contract, sometimes it provides for the possibility of an increase in the cost of work or materials upon bilateral agreement with the customer, but as a rule, such an increase is limited to an amount up to 10 or 15 % of the total contract value.
Profit can be lost even where you do not expect it at all.
Example:
We had one object where, among other things, we had to make porches or canopies over the entrances to the building. We had an estimate, which included the amount of metal needed for the installation of the porches in tons, and the project did not contain a word about how these porches should look, no diagrams or sketches. If I'm not mistaken, the estimate was about 300 kg. metal without specifying its type, dimensions, profile and thickness. In the estimate, this metal was listed as processed metal, that is, as finished metal products, which immediately increases their cost, probably twice as much as the cost of pure metal. Complete lack of clarity on how to do the job…
The technical supervision explained how to be something like this: “Do it normally, so that it is reliable and beautiful enough, but without frills …”
We looked at how this is usually done at other objects, figured out what metal would be needed, its thickness, sketched out how it would all look like, figured out that snow could fall on the visors from the roof … It seems everything turned out fine on paper. We bought metal, welded spatial frames, racks, assembled everything, painted it. We are waiting for acceptance by the construction supervisor .
