1, unit price method of preparation of construction budget:
(1) collect a variety of preparation based on information. Including construction drawings, construction organization design or construction program, the current construction and installation project budget quota, fee standards.
(2) familiar with the construction drawings and quotas.
(3) Calculate the amount of work. Calculation of the quantity of work is the most important and tedious part of the whole budget process, which not only affects the timeliness of budgeting, but more importantly, the accuracy of the budget cost.
(4) apply the unit price of the budget rate, the direct cost of the unit work. Apply unit price need to pay attention to the following points:
1) the name of the amount of sub-projects, specifications, units of measurement must be consistent with the budget quota or unit valuation table.
②When not exactly in line with, must be adjusted or converted according to the instructions on the fixed unit price.
③ When the difference is very far, must be prepared to supplement the unit valuation table or supplemental quotas.
(5) preparation of labor and material analysis table. Calculate and summarize the number of labor and materials required for each sub-part of the project, add up the number of various types of labor and materials required for the unit of work.
(6) Calculate other costs and summarize the cost. Calculate the measures, overhead, profit and taxes; in accordance with the provisions of the materials, labor, machinery bench budget price adjustment; and summarize the unit cost of the project.
(7) Review.
(8) Preparation of instructions and completion of the cover sheet.
2, the application of physical method of preparing the construction budget
First of all, according to the construction drawings were calculated separately the amount of sub-projects, and then apply the corresponding budget labor, materials, machinery, the fixed amount of work, and then multiplied by the location of the project at the time of the actual unit price of labor, materials, machinery, work.
Seeking out the unit of labor, materials and construction machinery costs, and summarize the sum, and then the direct cost of the project, and then according to the provisions of the other costs, after the summary of the unit of the project can be derived from the budget cost of the construction drawings.
Physical method of preparation of construction budget in the main formula is:
Unit project budget direct engineering cost = [∑ (volume of work × labor budget quota amount × local unit price of work days at that time) + ∑ (volume of work × material budget quota amount × local material budget unit price at that time) + ∑ (volume of work × construction machinery shift budget quota amount × local machinery shift unit price at that time)]]

I, investment estimation
Investment estimation refers to the project proposal and feasibility stage, by the construction unit or its commissioned consulting organization according to the project proposal, estimation index and similar projects of the relevant information on the proposed project to pre-estimate the investment required and determine the process. Investment estimation is the main basis for decision-making, financing and cost control.
Two, the design estimate
Design estimate is an important part of the design documents, is under the control of the investment estimate by the design unit according to the preliminary design (or technical design) drawings and descriptions of the proposed budget quota (or proposed budget indicators) cost standards, equipment, materials, budget prices and other information compiled to determine the construction of the project from the preparatory stage of the project to the delivery of the full cost of the document.
In a nutshell, the design estimate is based on the design requirements of the project cost approximation.
Design estimate is the project investment ceiling. Estimates according to the preparation of the order and scope of the size can be divided into unit project estimates, comprehensive estimates of individual projects and construction projects at three levels.
Unit project estimate is to determine the construction cost of each unit of the document, is the basis for the preparation of a comprehensive estimate of a single project, is an integral part of the comprehensive estimate of a single project.
(1) unit project estimates can be divided into two categories according to the nature of its engineering construction estimates, equipment and its installation project estimates.
(2) single project estimates. Comprehensive estimates for a single project is to determine the construction costs of a single project documents, is a single project by the unit project estimates are summarized and compiled, is a component of the total construction project estimates.
(3) the general estimate of the construction project. Construction project is to determine the total budget estimate for the entire construction project from preparation to completion and acceptance of all the costs of the document, is a comprehensive estimate of the single project, the construction of other cost estimates, reserve costs and interest on loans during the construction period summarized into.
