26、ies concerning the accuracy of measurement methods on building sites. Part 2 will deal with measuring stations and targets and part 3 will deal with setting-out drawings. 1 Scope This part of ISO 4463 deals with the progressive stages of setting-out work in building construction, i.e. acquisition of

27、 information, establishing the primary system, setting-out the secondary system, vertical transfer of points in the secondary system to other levels, and setting-out the position points and the establishment and transfer of levels (bench marks). In addition it gives values of permitted deviations an

28、d guidance on independent check measurements (quality control) using instruments and methods currently in common use at each stage of the setting-out process. 2 Field of application This part of ISO 4463 applies to common types of building construction. Special operations such as setting-out of prec

29、ision machinery or the legal location of the building, as specified for example in planning laws or local regulations, are not covered by this part of ISO 4463 since all recommendations are subject to statutory legislation in a particular country. 3 References ISO 1803-1, Building construction Toler

36、.1 The process of setting-out on any building site may be described as the determination and establishment of a well-defined system of lines, distances and planes to provide a suitable network for the determination of the accurate position and level of buildings and building elements. This Internati

37、onal Standard is concerned with the complete range of setting-out on building sites and thus adopts a three-stage order of reference systems which are commonly required for large and complex building projects. As shown in Figure 1, the order of establishment and connection of reference systems is as

38、 follows: a) Primary system, which is connected to the official control system 3)and normally covers the whole site and to which subsequent measurements on that site are related (see clause 14); b) Secondary system, which serves as the main reference system or grid for the erection of a particular b

39、uilding or group of buildings and associated works (see clause 15); c) Position points, which mark the location of individual elements, for instance columns and walls (see clause 16). 5.2 The choice of the number and type of reference systems required for a particular building project will be depend

40、ent on the size, complexity, and configuration of the site, the shape, size and position of each building, the amount of space available, the proposed methods of construction and the erection sequence. In practice, therefore, the previously established reference system from which the secondary setti

41、ng-out system can be established may be either an existing co-ordinate system which covers the particular site, that is an official control system; or a network of measuring points specially established for the building project, that is a primary system; or corner points or other important points re

42、lating to a particular building established for example by the local authority (see Figure 7); or in the case of an extension of a building or infilling between existing buildings, reference lines established by extending one or more secondary lines, for example lines parallel to the column centre-l

43、ines. 3) An official control system can be the national, municipal or other agreed higher order coordinate system.ISO4463-1:1989 (E) BSI 07-1999 3 NOTESome of the primary, secondary and position points are shown. Primary points are marked and measured in. Secondary and position points are set out an

Planning and organization of setting-out 6 Acquisition of information Detailed information is required on the size and shape of the site, planning regulations

45、, existing services, adjacent structures above and below ground, and the existing survey network. Some of this information is often available from the statutory authorities (local authority). A site survey to confirm and update the above information should be carried out. Such information will enabl

46、e the designer to relate the position of the proposed building and ancillary work to the survey system around the site and also facilitate the contractors reconnaissance for the setting-out work. 7 Planning the setting-out 7.1 Reconnaissance A reconnaissance of the site and planning of the setting-o

47、ut are essential. Based on the site survey drawing relating the building and ancillary work, a suitable reference system should be selected and established. The system selected will depend on the shape and size of the site and the position of any existing buildings or obstructions; the position of t

48、he proposed building and ancillary work; the sequence of excavation and construction. The chosen reference system should be such that redundant observations are possible and that the measuring points can be referred to during construction. The positions of the main ground stations should be chosen a

49、nd protected such that they are at minimum risk to damage or movement and unobstructed lines of sight can be maintained. Elevated permanent targets on existing buildings could serve this purpose but may be more difficult to use than protected stations on the ground. Primary and secondary benchmarks should be positioned such that change points are kept to a minimum and sight lengths do not exceed 40m. The type of instruments and the method of setting-out should be selected to meet the specifi
