Precast concrete—concrete which is placed, as plastic concrete, in a location other than in its final location as part of the permanent structure. Any limitations on the magnitude and locations of stacked materials and minimum concrete strength to be achieved prior to the stacking of materials.

The engineer shall certify that the following has occurred: Readings shall be taken along the length of the walls at not more than 5 m centres. Bearing area—effective area over which a force is transferred to a supporting structural system. This term includes the forms on which the concrete is poured, the supports which withstand the loads imposed by the forms and the concrete, the bracing which may be added to ensure stability, and the footings. Limitations on the use of the permanent structure for the restraint of formwork.

If the angular dimensions checked under Item c above comply with the specified tolerances, check the profile for compliance with the tolerances specified in accordance with Clause 3. The requirements of this Section apply in addition to the instructions given in the formwork documentation see Sections 2, 3, and 4. The results of the test, which shall cover the following where relevant: For unidentified materials, the additional requirements of Clause 4.

Soffit formwork—formwork to the undersides of slabs, beams and the like. The test results may be used as the basis of acceptance of all components or assemblies in the cnocrete from which the prototype test units were formwori. Some guidance in respect to these loads may be obtained from BS Element—portion of the permanent structure delineated by formed concrete faces, construction joints and the completed concrete surfaces, which is poured in one continuous operation.

Details of and information on the effect of the post-tensioning procedures on the formwork and any special procedures to be adopted in the stripping of formwork. Foundation—soil, subsoil or rock, whether built up or natural, upon which the permanent structure or the formwork is supported.

SIA Specify If Applicable—these are mandatory where the particular feature is included in the project documentation. See Note to Clause 5. It was approved on behalf of the Council of Standards Australia on 18 January and published on 5 April The value ax prestress or post-tensioning strain hog and shortening is influenced by variation in material properties in a similar way to that of other permanent load effects see AS A Commentary has been added flr Table 3.

Where the shape of a precast unit is such that there is conflict between the abovementioned Clauses and those indicated in Item b below, Item b shall take precedence. When standard beam or cylinder tests are used to determine stripping times, test specimens shall be cured under conditions which are not more favourable than the most unfavourable conditions for the portions of the concrete which the test specimens represent.

No part of this wor k may be rep roduced or c opied in an y form or by any means, electronic or mechanical, including photocopying, without the written permission of the publisher. It is possible that there will be small sections of the 1: Movement of the forms after the initial setting flrmwork the concrete shall be prevented.

Where the eccentricity can apply in more than one direction, the test load s shall be applied with the eccentricity in the least favourable direction for the formwork component or assembly being tested. Second editi on To be acceptable the surface of the completed work shall show a consistent surface texture within the acceptable variation of the surface treatment in which the test panel is included.

Warp tolerance shall be expressed as the maximum acceptable distance of any point on a surface from a plane containing any three corners of the surface or points on the perimeter of the unit.

It provides information on the loading to be considered in the design of cpncrete formwork assembly see Clause 4. Attention is drawn to Clause 3.

Design by testing is considered separately, the requirements being set out in Appendix A. Thank you for interesting in our services.

Tolerances in angular dimensions Tolerances in angular dimensions cover squareness or trueness to any specified angle see Figure 3. Formwork Guide Best practices for safe and effective formwork in construction. They reflect the latest scientific and industry experience.

May—indicates a practice which complies with the requirements of this Standard. The details set out in Formwkrk 3. Reshores—adjustable supports placed to give support to the permanent cor after the formwork to the soffits in the area has been removed. This Standard was issued in draft form for comment as DR In the absence of site recording, local temperatures are usually available from the Australian Bureau of Meteorology.

Where the lowest set of supports is seated on a suspended floor structure the minimum loads on the formwork shall be not less than 2. Permissible stress procedures, in accordance with the appropriate material structural design code and Clause 4.

Unless specified otherwise, the plumb of columns shall be checked at two positions as follows: In some cases the maximum eccentricity may not occur under maximum load. This term includes undisturbed supports, backprops and reshores. Method of provision for field adjustment of the forms prior to and during placement of the concrete. Photographic charts for the assessment of colour and surface finish are provided in the appendices. The objective of this Standard is to set out requirements for the design, fabrication, erection and stripping of formwork as well as evaluation of the formed concrete surface.

Requirements for propping of any composite construction. For structures or components other than proprietary items, the load carrying capacity is obtained from the appropriate material design Standard. Test panel—a concrete element constructed, prior to the commencement of the permanent structure, as an example of materials and quality of work.

In some cases backpropping gives no advantage. Where strain movement of the concrete is possible, deviations shall be measured prior to removal of any forms or supports or application of prestress or post-tensioning. This Standard has limited applications for unformed concrete surfaces e.
