Entering the new century, the residential development and construction with China characteristics is facing a new revolution. Advocating the brand positioning concept of people-oriented and harmony between man and nature, the requirements from planning and design, architectural design, apartment design and building materials adoption to function and quality are getting higher and higher. As a real estate development enterprise, the first requirement is short construction period and good investment benefit. In view of these situations of real estate projects, we must implement effective cost control in the whole process of project investment, tap the potential from the aspects of organization, technology, economy, contract and information, reduce the cost and improve the investment benefit and social benefit. In this paper, some opinions on the project cost control in the design stage, bidding stage, construction stage and completion settlement stage, which have great influence on the project cost, are discussed, which will play a role in attracting jade.

First, the design stage of cost control

The design stage is the key and emphasis of real estate project cost control. Although the proportion of design fees in the whole process of construction projects is small, generally only accounting for 1.5%-2% of the construction cost, the impact on the project cost can reach more than 75%. It can be seen that the quality of design directly affects the amount of project cost and the length of construction period, and directly determines the amount of manpower, material resources and financial resources invested. Reasonable and scientific design can reduce the project cost by 10%. However, in engineering design, many designers pay more attention to technology than economy, and raise the safety factor or design standard at will without paying much attention to economic rationality, which fundamentally affects the effective control of engineering cost. For example, the elevator shaft corridor on each floor of a high-rise residential building is only 10 meters away, and there is no fire zone in the middle, so three fire boxes are set up. According to the requirements of the fire protection code, as long as two water guns reach any part of the room at the same time, this design is unreasonable and leads to certain waste. Obviously, the economic indicators of the project have not been paid enough attention. Therefore, the impact of the design stage on the project investment is extremely important, especially the impact of the initial expansion design stage on the project economy is 70%-95%. In fact, after the initial capacity expansion design is approved, the existing technical problems and cost problems are difficult to solve, so we must pay attention to the initial capacity expansion design to avoid it.

1. Conduct design bidding and select the best design unit.

Actively promote the design bidding method combining architectural scheme with economic scheme, try to put the main body of the project and supporting enclosure and greening together for bidding, take multiple tenders, and organize relevant experts to conduct comprehensive evaluation. This can not only optimize the design unit, but also promote designers to innovate in the overall layout of the project and the use function of architectural modeling, and make efforts to reduce the project cost.

2. Conduct quota design to effectively control costs.

Actively carry out quota design and improve the economic responsibility system for design. Designers should be familiar with the budget quota, cost quota and budget price of building materials, then control the preliminary design and budget estimate according to the project investment estimate, and then control the construction drawing design and budget estimate with the preliminary design budget estimate. Therefore, under the premise of ensuring the function and technical indicators, each major must formulate a win-win strategy, rationally decompose and use the investment quota, and integrate the construction drawing design with the construction drawing budget. Organically combine technology with economy. Strictly control design changes to ensure that the investment limit is not easily exceeded. The project cost management personnel of real estate development enterprises should actively cooperate with the design department to provide reliable basic engineering data in time.

At present, the design is not fine and the depth is not enough. This is an uncertain factor that increases the project cost. Due to frequent design changes, the project cost is difficult to control. According to the requirements of development experience and investment estimation, it is necessary to effectively determine the design limit (cost, three-material consumption index, etc.). ) and establish a reward and punishment assessment incentive mechanism. For which major or plate breaks through the cost index, it is necessary to analyze the reasons. To solve this problem, it is necessary to modify the design, overcome the tendency of attaching importance to drawing only, and change "drawing calculation" into "drawing calculation". The technical indexes of similar construction projects should be used for scientific analysis, comparison and optimization design to reduce the project cost.
