The estimate – one of the main documents on which the quality of repair work depends. Contractors who in that case receive full carte blanche over financing of the project most often are engaged in preparation of the estimate. For the customer it is important to know that in the estimate there are no additions and excess cost items. And it is possible to find confidence in it only if to develop the estimate independently.
Preparation of the estimate for the person far from specifics of building and construction works, has to begin with definition of task. First of all it is necessary to understand, it is necessary to carry out repair of what – rooms in general, separate rooms, the local site.
Depending on task, repair can be referred to capital or cosmetic. Major repair demands introduction in engineering stuffing of the building therefore it will be difficult to make the estimate in such large-scale area of work. It is the simplest to prepare independently estimates on renovation.
Inventory
Independent development of the estimate and studying specifics of repair process often lead to understanding that some works can be performed safely independently, some building materials can be not bought, and to use already available, and part of tools already is available.
Therefore it is necessary to carry out audit of the available building materials and stock most of which often dead cargo settles on balconies, in storerooms and garages. Listing the available equipment, it is important to make in parallel the list of necessary materials and tools which should be bought.
Seeing the available reserves and all profiles of work, it is necessary to define – what front of work to entrust experts and what can be executed by own efforts. All articles of the estimate on which implementation the involvement of contractors will be required should be included in monitoring of the prices in the market. It is necessary to lean on average and maximum rate on category. It is necessary to exclude suspiciously cheap offers of contract organizations from monitoring at once. Most likely, they perform work substandardly or in their price list there are holes which will only reduce objectivity of the made estimate.
Cost of building materials
The next stage – carrying out monitoring of the prices of necessary stoymateriala. It is necessary to study offers of construction hypermarkets, online stores and private suppliers. Discount campaigns should be taken into account only if the term of their action coincides with approximate date of purchase.
Material consumption is calculated from amount of works and indicator of the normal consumption rate specified on material packing. At any building and construction works it is necessary to provide stock in the amount of 15% for each of types of the used construction material. The surplus which remains after repair is useful for small seal, need for which can appear already in use.
Force majeure
Even the most detailed construction estimate finally goes beyond the designated financial threshold in plus or in minus. It is connected with instability of the prices of construction materials, the equipment and services. It is important to provide such force majeurs. For this purpose total amount just should be increased by 1.5.
