| For comprehensive realization in CHINA Petrochemical Corporation, provincial party committee, provincial government about urban shantytown transformation implementation opinion, enhances the minority groups the housing level, and advances the Jilin petrochemical shantytown rebuilding project is the Jilin Petrochemical Mining Area Service department with all one's strength in work on the 11th and 12th Five-Year Plan. During the year of 2006-2008, Jilin petrochemical corporation had been organized to implement successively the rebuilding projects on the Tiebei Community of Jilin Chemical Industrial Company Limited, the Tubei Community, the Tunan Community, the Songjiang District Community and the Tienan Community shantytown. In 2009-2010, we will develop the local dangerous or old one-story house and the Yushugou Community shantytown's rebuilding project one after another.Because the shantytown rebuilding project investment cost is very huge, and must place returns to original home or work the resident completely, uses in the house which sells being limited, causes this project unmet needs to be big. Building cost of projects' control has the very vital significance.Looking over the engineering construction project entire process, building cost of project's control penetration in project construction each stage, but the investment decision stage affects to the entire project construction cost's influence is 75%-95%, design stage's influence is 35%-75%, the construction stage is 5%-35%, completion stage is 0-5% from some pertinent data analysis indicated. Obviously, after the project investment decision determination, the design stage is the control engineering construction cost critical phase. But in the actual work, the design stage building cost of project's active control is often neglected by the people. Therefore, this article obtains from the elaboration design stage building cost of project control's necessity, designs each stage as the object of study, utilization methods and the theory and such as the value engineering, quota design, modular design, elaborated how the shantytown improvement project does carry on the construction cost control in the design stage, thus achieves reduces the project investment the goal. The shantytown rebuilding engineering design stage investment control seeks for the theory and the actual foundation for 2009.The full text divides into five parts:The first part: To the Jilin petrochemical shantytown rebuilding project's background, the characteristic have made the simple introduction, explained the selected topic goal and the significance. The Jilin petrochemical shantytown rebuilding project implement five communities from 2006 to 2008, the project total investment 751,320,000 Yuan, the unmet needs are big. Specially aims at the question which in the present design stage building cost of projects control exists. Pointed out that is imminent in the design stage active control building cost of projects. The research design stage building cost of projects control takes each stage which designs as an object, utilizes a set of effective control procedure and the method, achieves the control engineering construction cost, reduces the project cost the goal. This article hoped that can cause everybody to the item design stage construction cost control value, raises the design stage construction cost control level earnestly, the guarantee design stage construction cost control quality.The second part: On the brief elaboration from the theory angle to the design stage building cost of projects control. First introduced the design main routine, as well as the design preparation, the project design, the preliminary design, the construction drawing design, the design give the low-down with the coordination construct various stages work content. Next narration building cost of projects control concept, and briefing value engineering, quota design, modular design basic principle. The ultimate analysis residential district plan, the total plane layout, the unit composition, the building store height, the layer, the structure type, the material have selected and so on factors to the residence construct building cost of projects influence, had pointed out the design stage control engineering construction cost must study object.The third part: Using the design stage building cost of projects control's principle, how to use the value engineering optimal shantytown rebuilding project design proposal in details. Take the housing design proposal as the value analysis object, is suitable to the housing, safe, carries on the function artistically the definition and the appraisal, the different design proposal its function size is different, the cost is different, extracts the function appraisal coefficient, the cost coefficient, the value coefficient. The function appraisal coefficient score is higher, the showing plan more satisfied function request, the cost coefficient is lower, the value coefficient is bigger is better. Finally it Has chosen the plan that first floor garage 3.3 meter high, the key bed building store height 2.8 meters, the outer wall is finally 370 red brick walls, the 80mm benzene board heat preservation, models the metal window, the settling tube filling pile.Take the identical plan as the example, elaborated to work pieces and so on foundation engineering, principal part, outer wall heat preservation project, water and electricity project has made the project cost improvement the method. We utilize the value engineering management the expert carries on the allocation law, obtains each main work piece function score, extracts the function appraisal coefficient, the use present estimated cost, extracts cost coefficient C, thus extracts the value coefficient V, carries on the analysis after the function coefficient, determination improvement order and improvement direction.Also described in this part has designed various stages quota design, the modular design idea application and the promotion. The implementation quota design must first through to the existence information collection, the reorganization, the analysis, survey the science, the accurate investment estimate. Then, the conceptual phase after the approving investment estimate quota, through the multi-plan's choice quite, causes the investment estimate to further make concrete. And it will stipulate an investment quota minute specialized issuing, carries on the design strictly according to the investment quota which the quota design decomposes. In the construction drawing design stage, strictly carries on the design according to the authorized preliminary design and the preliminary design budgetary estimate, should place in with emphasis the resilience control, the control resilience is after the examination preliminary design resilience, and as the construction drawing design resilience's ceiling, do not break through. The promoted standardization design concrete procedure is in the design standard, the standard select on unify the request. In the identical plot, the different monomer identical area's house designs as far as possible for the unified household, but must promote the new material, the new craft use positively. These made the law not only to reduce the building cost of projects moreover to speed up the design and but also the construction progress greatly.The fourth part: Stands in the management situation, elaborated the institutional means which the control design stage project makes: Establishes the effective drive competitive system, consummates the design to incur the bid system, the reform design takes spends the way, introduces take the Designing department gradually as the main body project primary contractor system; Simultaneously strengthens design management dynamics, consciousness which the enhancement design technique and the economy unify, enlarges to designs with design alteration supervision dynamics, guaranteed that the building cost of projects control the effective implementation, reduces the building cost of projects.At the end of article, take the Tubei Community as the example, has given the affirmation with the actual illustration to the design stage building cost of project control's actual effect. And it analyzes the new question which in 2009 the shantytown rebuilding project will meet.In brief, items of basic construction's construction cost control is a complex systems engineering, not only involves the specialized surface is broad, moreover involves to items of basic construction participation all quarters, including owner, overseeing, Designing department, Construction, government related department etc. All quarters play any role in the construction cost control, how to improve the method of design stage construction cost control, enables it to have the usability, these are the topics which is worth discussing in the future. |
