4、mme of work undertaken by CEN to make available a common set of standards for execution of concrete structures. This publication is not to be regarded as a British Standard. It is being issued in the Draft for Development series of publications and is of a provisional nature. It should be applied on
5、 this provisional basis, so that information and experience of its practical application mat be obtained. Comments arising from the use of this Draft for Development are requested so that UK experience can be reported to the European organization responsible for its conversion into a European Standa
6、rd. A review of this publication will be initiated 2 years after its publication by the European organization so that a decision can be taken on its status at the end of its three-year life. The commencement of the review period will be notified by an announcement in Update Standards. According to t
7、he replies received by the end of the review period, the responsible BSI Committee will decide whether to support the conversion into a European Standard, to extend the life of the prestandard or to withdraw it. Comments should be sent in writing to the Secretary of BSI Subcommittee B/525/2, Structu

11、NV 13670-1 January 2000 ICS 91.010.30; 91.080.40 English version Execution of concrete structures - Part 1: Common This European Prestandard (ENV) was approved by CEN on 27 November 1999 as a prospective standard for provisional application. The period of validity of this ENV is limited initially to
12、 three years. After two years the members of CEN will be requested to submit their comments, particularly on the question whether the ENV can be converted into a European Standard. CEN members are required to announce the existence of this ENV in the same way as for an EN and to make the ENV availab
13、le promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the ENV) until the final decision about the possible conversion of the ENV into an EN is reached. CEN members are the national standards bodies of Austria, Belgium,
14、 Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.

24、restandard has been prepared by Technical Committee CEN/TC 104 “Concrete (performance, production, placing and compliance criteria)“, the secretariat of which is held by DIN. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound
25、to announce this European Prestandard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. Because of the close connection between design rules and rules fo
26、r execution, CEN/TC 104/SC 2 has developed this prestandard in conjunction with CEN/TC 250/SC 2. This prestandard supersedes the execution and tolerance clauses in ENV 1992-1 Eurocode 2: Design of concrete structures and the execution rules in prEN 206:1997: Concrete - Performance, production, placi
27、ng and compliance criteria. This prestandard specifies the required level of execution in assembling products such as fresh concrete, reinforcement, precast concrete elements etc. into a structure that achieves the intended level of mechanical resistance and stability. This prestandard has three fun
28、ctions: to transfer the requirements set during design from the designer to the constructor i.e. to be link between design and execution; to give a set of standardized technical requirements for the execution when ordering a concrete structure; to serve as a check list for the designer to ensure tha
29、t he provides the constructor with all relevant technical information for the execution of the structure (see Annex A). Page 5 ENV 13670-1:2000 Introduction (1) This European Prestandard assumes: the availability of a comprehensive design of the structure a project management in charge of the superv
30、ision of the works which will ensure the execution of a conforming structure; a site management which will take charge of the organisation of the works and ensure the correct and safe use of the equipment and machinery, the satisfactory quality of materials, the execution of a conforming structure a
31、nd its safe use up to the delivery of the works. When precast elements are used, the following additional assumptions are made: the availability of a specific design of the precast elements conforming to the relevant standards the availability of a design coordination between precast elements and si
32、te manufactured components. a technical specification of the precast structure with instructions for installation; there is an erection management to direct the erection team. (2) This European Prestandard presupposes that the work is carried out with the necessary skill and adequate equipment and r
33、esources to perform the work in accordance with the requirements of the project specification and the requirements of this European Prestandard. It is assumed that generally accepted rules for good workmanship for the various activities are known and applied. (3) It is assumed that the constructor w
34、ill conform to provisions valid at the construction site with respect to: qualifications for the personnel doing the various activities covered by this prestandard; health and safety aspects of construction. (4) This prestandard assumes that the finished structure after completion is used as intende
35、d in the design and submitted to the planned inspection and maintenance necessary to achieve the intended design life and to detect weaknesses or any unexpected behaviour. 1 Scope (1) This European Prestandard gives common requirements for execution of concrete structures. In particular, this part g
36、ives requirements for structures designed according to ENV 1992 -1 and for the concrete part of composite structures designed according to ENV 1994-1. (2) In the case of civil engineering works, different or additional requirements need to be considered and, if required, given in the project specifi
37、cation. (3) This prestandard permits the project specification to state specific requirements relevant to the particular structure. (4) This prestandard is applicable to temporary as well as permanent concrete structures. (5) Additional or different requirements should be considered and, if required
38、, given in the project specification when using: Lightweight aggregate concrete; other materials (e.g.fibres) or constituent materials; special technologies/innovate designs. (6) Small and simple concrete works and secondary structures of minor importance, defined as such in provisions valid at the
39、construction site, are not within this prestandard. (7) This prestandard does not apply to concrete members used only as equipment for the execution. (8) This prestandard does not cover the specification, production and conformity of concrete. Page 6 ENV 13670-1:2000 (9) This prestandard is not appl
40、icable to the production of precast concrete elements made in accordance with product standards. (10) This prestandard does not cover the requirements for concrete members in special geotechnical works such as pile foundations, ground anchors, slurry walls, etc. (11) This prestandard does not cover
41、safety and health aspects of execution. (12) This prestandard does not state requirements for quality assurance or for qualification of personnel for the various activities. (13) This prestandard does not cover contractual issues or responsibilities for the identified actions. 2 References (1) This
42、European Prestandard incorporates by dated or undated reference, provisions from other publications. These references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications ap
43、ply to this European Prestandard, only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies.
