Cash needed to create construction products represent the cost of construction.To calculate this cost developed special documents - construction cost, which is calculated estimated value.Estimate documentation detail reveals all construction costs.Based on this contract is a contract.
Preparation of construction budgets passed, we can say, in 3 stages:
- Making local estimates.
- Drawing object estimates.
- Consolidated estimate calculation of construction cost.
local estimates - is the original cost estimate document, which provides estimates of costs for specific types of work.On the basis of this type of document, as a result, generated summary estimate.To compile this business paper, so-called Thera (territorial unit prices) and the estimated ratios (enlarged), which allow you to accurately calculate all the construction in a particular region.
local estimates can be made using two different methods: a resource and basic-index.Applying resource method, the construction cost is calculated at current prices.In the base-cost calculation of the index approach is due to the specially developed indexes created to recalculate the estimated value of the basic current prices.Each year the index changed, so the cost is calculated as accurately as possible.
Object estimate consists of local budgets, grouped in the following operations and costs:
• construction works;
• mounting;
• Equipment, furniture and fixtures;
• other works.
calculation object estimate is made by adding the local current or basic prices and amounts for the whole object.For its calculation using aggregated standards and parameters of analog objects in terms of value.Contract prices on the object formed on the basis of this type of documentation.
Consolidated budget calculation is a document laying down the estimated cost of construction for all the objects included in the project.On the basis of its decision to finance the construction.
Consolidated budget calculation determines the effectiveness of the considered project design.When calculating the cost of housing and civil and industrial construction is divided into chapters, after which, beginning with the eighth, given the calculation of totals.In him all the object of making estimates grouped on the same work.
Also be aware that the summary estimate must be drawn up for the construction of a whole, regardless of the number of participating contractors.Attached is an explanatory note with all the information on the building where it will be held, regulations adopted for the documentation, the expected profit.
Compilation of all these documents can be carried out both on paper (hand-written), as well as in electronic form (in Excel or special software products).For example, estimates or GrandSmeta Wizard - quite a decent solution.
Estimate documentation shall be made in the prescribed manner, no matter how the building - under the contract or the economic means.
