That a test report has been prepared in accordance with this Standard. Any other relevant information such as signs of distress prior to failure. NA Not Applicable—these are matters which are not applicable to the particular class.

Requirements for the minimum number of levels of supports relative to the type of formwork, timing and sequence of its use, the anticipated time between construction of subsequent floors and the expected ambient temperature for multistorey structures.
Face steps Readings shall be at mm intervals for the full length of the concrwte step. Products which have become commercially available since the publication of CIRIA Report in should be investigated to determine whether they should be classified as retarders. Prop— a structural member loaded in compression. Alternatively, the load modification factor based on the weighted average as determined in Clause 4. This Standard incorporates Amendment No.
FORMWORK – THE CODE STATUS
Formwork—the surface, supports and framing used to define the shape of concrete until it is self-supporting. It also sets out the requirements for the fabrication, erection, inspection and stripping of formwork. To maintain their currency, all Standards are periodically reviewed, and new editions are published.
Between editions, amendments may be issued. This Section does not apply to unformed concrete surfaces, or to the faces of concrete elements constructed from permanent formwork. This section covers the provision of this information.
For formwork members other than primary members the global load factor shall be taken as 1. Vibration The formwork shall be designed and constructed to have sufficient stiffness, mass, or both, to avoid any detrimental effect of vibration on its structural capacity, tolerances, surface finish and safety. Fprmwork part of this work may be reproduced or copied in any form or by any means, electronic or mechanical, including photocopying, without the written permission of the publisher.
Wind loads may be assumed not to act during Stage II except in the unusual situation where the combination of dead, live and wind loads could be more critical than in Stages I or Formworkk.
Second editi on 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. Tonal scale—the graded set of grey tones provided in this Standard, or prepared by the project designer when special concrete is used, for evaluation of the colour of the concrete surface.
Preparation of the foundation, such as filling and compaction and drainage. Although no limitation is placed on the sample size, attention is drawn to the sampling factor k s see Table A1 which reduces as the sample size increases.
Surface treatment—the removal of a specified depth of the concrete of the permanent surface by a nominated mechanical means such as sand blasting or jack picking. Where these early concrete strengths are not achieved, the times given shall be increased by a factor of 1. The relevant deviations shall be calculated separately from those defined in ab and c above.
CP23 Formwork Full description. Regulatory authority— a body having statutory powers to control the design and erection of the formwork. For tension members see Clause 4. Limit state separate desired state no failure from undesired state failure. The objective of this Standard is to provide formwork architects; engineers; builders and construction contractors; and formwork designers, suppliers and contractors with requirements for the documentation, fabrication, erection and stripping of formwork, as well as for the assessment and evaluation of completed surface quality and repairs.

The following are represented on Committee BD In the absence of such specified minimum times, Table 5. Strength The formwork assembly and its component members shall withstand the effects of all appropriate load combinations.
It was approved on behalf of the Council of Standards Australia on 18 January and published on 5 April Undisturbed support—compression member which, as part of a soffit formwork, remains undisturbed in place until the permanent structure is strong enough to support itself even though the forms have been removed earlier. Details of and information on the effect of cocrete post-tensioning procedures on the formwork and any special procedures to be adopted in the stripping of formwork.
Formwork – Standards Australia
Where a tonal scale is used the tonal range of the accepted foormwork panel shall be recorded as set out in Clause 5. 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. Where indicators are installed, they shall be monitored to facilitate the detection of concree settlement or distortion during concreting. NA indicates not applicable.
There shall be NO stacked materials on any of the floors. The service load divided by the slab self weight shall be greater than 1. Permanent structure—the structure for which the formwork is required.
If backpropping is to be cocrete, the number of levels of the supports in the Table shall be increased by one. Please help us to share our service with your friends.
