Quota of Assembled Concrete Construction Project in Jiangsu Province
Engineering construction mode
1, engineering construction procedure
The sequence to be followed in the whole process of engineering construction:
(1) Decision-making stage-project proposal, site selection opinion, feasibility study report and planning permission for construction land.
(2) Implementation stage-preliminary design, preliminary design and budget approval, construction drawing design, construction project planning permission, construction drawing design, document review, construction bidding and contracting, quality supervision, construction permission and site construction.
(3) Completion stage-completion acceptance, quality supervision report, completion acceptance filing and handover.
3, the meaning of prefabricated buildings
Prefabricated building refers to the building assembled by prefabricated components and parts on site.
Prefabricated building is a systematic project, which integrates prefabricated components and components through system integration to realize the integration of main structure, enclosure structure, equipment pipeline and decoration, mainly including prefabricated concrete building, prefabricated steel structure building and prefabricated wood structure building.
Assembled building engineering should have the basic characteristics of standardized design, factory production, assembled construction, integrated decoration and information management. This is the development direction of prefabricated buildings. At this stage, the key contents of developing prefabricated buildings include:
(1) The main structure is transformed from the application of prefabricated components to the overall assembly of the structure;
(2) Integrated development of decoration and main structure, encouraging assembled decoration;
(3) standardized application and product integration of parts;
(4) The application of information technology in the whole process of design, production, construction and supervision.
Assembled concrete building: it is an assembled building whose main structure is composed of concrete members. Assembled concrete building is a concrete building with cast-in-place main structure. The main structure, enclosure components, internal components and equipment pipelines of the load-bearing wall, column, beam, floor slab, external wall panel, stairs, air conditioning panel, balcony and parapet are prefabricated in the factory and assembled on site, which realizes the transformation of construction mode, improves the engineering quality and efficiency, reduces the labor intensity and reduces the waste discharge of on-site construction.
Assembly rate: the ratio of the number of prefabricated components and parts above 0.000 elevation to the number of similar components and parts in prefabricated buildings. See Su Jianke [2065438+07] No.39 for specific calculation.
Article 8 of the Opinions of the Provincial Government on Accelerating the Development of the Construction Industry and Building a Strong Building Province (Su [2011] No.58) requires: guide construction enterprises to accelerate the process of building industrialization, adopt advanced and applicable technologies, take assembly-type production and assembly-type construction as production methods, and feature design standardization, modularization and construction mechanization.
Engineering construction cost
1. The construction process of prefabricated buildings can be divided into three stages: component manufacturing, transportation and assembly construction, which correspond to manufacturing, transportation and construction respectively. The composition of the overall project cost cannot simply follow the "Provisions on the Division of Construction and Installation Project Cost".
2. As an industrial finished product, the price composition of spare parts should follow the price composition of industrial products. The price of industrial products can be divided into ex-factory price and retail price. Ex-factory price consists of production cost plus profit and tax, in which production cost consists of manufacturing cost and period cost.
5. Main problems in the compilation of valuation quota for assembled concrete projects.
(1) There is no market transaction case, so it is difficult to verify the construction cost and profit.
(2) The degree of industrialization is quite different, which breaks through the boundaries of traditional professional division of labor projects.
(3) The design standardization is not in place, and the cost comparison and analysis are difficult.
(4) The composition of project cost changes, and the price policy needs to be studied.
6. At present, the price system of assembled concrete engineering is constructed.
(1) Time limit for a project-Su Jian Jia Jia [20 16] No.740 shall be implemented.
(2) Assembly engineering cost quota: component production budget quota, component transportation budget quota, on-site installation budget quota, labor, materials, mechanical machine-team price.
(4) Supplementary rules for valuation of quantities.
(5) Building industrialization cost information-compiled and released when conditions are ripe.
7. Principles for compiling the quota system of assembled concrete engineering
(1) Strive to build an independent quota system, not considering it as a supplementary quota. Starting from the current concrete structure system in Jiangsu Province, with the maturity and wide application of other systems, the system coverage of building industrialization quota will gradually expand.
The changes in the construction process brought by the assembled construction method have broken the traditional pattern of dividing the pricing system by specialty; The price composition, management fee and profit calculation method of assembled construction mode have changed; Accounting caliber changes in labor wages, unit price of assembly structure and other related expenses.
(2) Strictly define the scope of application of the quota. When compiling the budget quota of industrial building products, it is necessary to match the corresponding cost quota at the same time, and the standard of applying the quota should be clear, and the assembly engineering quota can only be applied when the assembly degree reaches a certain level.
(3) Actively promote the matching and implementation of technical standards. Connection with existing codes and standards. Strictly implement the relevant national engineering construction standards; Strictly implement the national and provincial standards, specifications and standard atlas requirements related to the modernization of the construction industry.
(4) All kinds of prepaid expenses are gradually put in place.
9, cost quota
Engineering categories of precast concrete construction projects
(1) Independent lifting project of concrete members: refers to the lifting project of concrete members contracted separately. Project contracting includes hoisting, grouting and fixing of concrete members on the construction site.
(2) Assembled concrete construction engineering: refers to civil engineering that meets the standards for assembled concrete construction engineering (Z 1≥30%). However, the steel structure fabrication and installation, pile foundation engineering, foundation pit support, large-scale earthwork, supporting projects and separate decoration projects (including curtain wall projects) in the project contracting content should be listed separately, and the construction project cost quota of Jiangsu Province (20 14) should be implemented.
"Jiangsu province assembly concrete construction project cost quota" and "Jiangsu province construction project cost quota" (20 14) shall be implemented together.
