The design phase of project cost control
Engineering design of construction projects is to conduct a comprehensive planning and specific intent to describe the process of implementation is the soul of the construction, dealing with technology and the critical link in economic relations, is to determine and control the key stages of project cost.
1, optimized design, the effective control of project cost.
Design quality and to try whether the state, functions are used to meet requirements related to construction projects only a one-time investment to meet the application requirements, not only construction projects related to the number of one-time investment, and after completion of delivery of the impact of the economic benefits of the project. Foreign experts pointed out that although the design of the project costs represent a small proportion of total investment, less than 1%, but its impact on the level of project cost 75 %. It is clear that the project design stage to do a good job of cost control is cost effective control of the key, re-construction, light design concept must be overcome to control the cost of the project design should start. Therefore, the construction units and design units in the review of the design, attention should be paid to design optimization, the use of various indicators of the overall plan of the factory, industrial building design analysis of space compared to the design of these two aspects of the project cost, not only have a significant impact, and after the construction and operation of the production, management has a significant impact. In the choice of process technology options, from the reality of our country in order to improve investment returns for the premise of a positive and safe use of advanced technology programs and mature new technologies and new techniques. In general, the advanced technology program of high labor productivity, product quality, but large investments required, therefore, has to carry out economic analysis, according to China's national conditions and the economic strength of enterprises, to determine the application of advanced, economical, practical technology program. In industrial construction projects, investment in equipment construction investment accounting for about 40% - 50 %, In the device design and modeling process should be standardized as far as possible, and serialization of generic production equipment, as far as possible based on domestic and imported equipment for the need to pay attention to and processes should be adapted and with the equipment, do not repeat the introduction.
2, the implementation of limits on the design of the project
Cost control process, used in the design limit of the design process. The so-called limit is in accordance with the approved design of the study can estimate the investment in the preliminary design of the control, in accordance with the approved budget for the preliminary design of the total control of the technical design and design of facilities, at the same time to achieve certification of professions in the premise of the use of functional according to the allocation of investment limit for control design, and strictly control unreasonable changes, permits will not be a total investment of a breakthrough. Decomposition process is the investment and is an effective way to limit the design and the main method, which is on the stage of the design and validation of the investment volume of the first decomposition process to the various professions, and then break down into various units and the way Division-way, pass decomposition levels, limits on investment to achieve the control and management, but also at the same time on the design specifications, design standards, process the number of indicators and over all aspects of budget control. The preliminary design stage should be in accordance with the approved feasibility study stage to estimate the investment limit of the design, control of non-super investment budget estimate, mainly on the way it is and equipment, materials control. To this end, the preliminary design phase of the design process limits the amount should be able to study the design stage of the validation process and equipment, material criteria, studies can be difficult to set a stage more Way traffic, be guided by the design and universal design, or similar kind of way-way volume. Quota at the preliminary design, the various professional designers cost way to enhance the awareness, in strict accordance with the decomposition of the limit design and control of the investment process permits the use of volume and function under design, seeks to process cost and process control in the limit. In order to encourage, to process cost and process control in the limit. In order to encourage the designer to do a good job in the design of choice to fight the introduction of the design of the mechanism, it is the design of the tender, designers struggle to enhance awareness and increase a sense of crisis and urgency of a sense of overcoming and Du selected than the one-sidedness and limitations, and Transcendentalism.
