2 Table of changes Change No. Date Scope Amdt Amended to move reference to a national authority to the foreword, and to update referenced standards. Acknowledgement The SABS Standards Division wishes to acknowledge the input of the Joint Structural Division of the South African Institution of Civil Engineering and the Institution of Structural Engineers and the Cement and Concrete Institute in the development of this document. Foreword This South African standard was approved by National Committee SABS TC 59, Construction standards, in accordance with procedures of the SABS Standards Division, in compliance with annex 3 of the WTO/TBT agreement. This document was published in May This document supersedes SANS 2001-CC1:2007 (edition 1). A vertical line in the margin shows where the text has been technically modified by amendment No. 1 This document is referenced in the Regulations of the Construction Industry Development Board Act, 2000 (Act No. 38 of 2000). Reference is made in to the relevant national authority. In South Africa, this means the South African National Accreditation System (SANAS). Amdt 1 SANS 2001 consists of a number of parts in various stages of preparation, under the general title Construction works. Annex A forms an integral part of this document. Annex B is for information only. Introduction The different parts of SANS 2001 each address a specific component of construction works. The prime purpose in the production of these standards is to create a set of standards that are generally applicable to construction works, and which can be readily modified to make them applicable to particular works. The SANS 2001 family of standards provides technical descriptions of the standard of materials and workmanship that will be used in the works that are executed or in the performance of the works when completed (or both). These standards do not make reference to the actions of those responsible for executing the works or the parties to a contract, i.e. to the constraints relating to the manner in which contract work is to be performed. Neither do they deal with the commercial arrangements of such contracts. These standards are suitable for use in any in-house construction work or in all types of engineering and construction works contracts, for example, design by employer, design and build, develop and construct, construction management or management contracts. Standard requirements pertaining to the manner in which works are constructed can be found in the SANS 1921 family of standards.

5 Construction works Part CC1: Concrete works (structural) 1 Scope This part of SANS 2001 covers concrete works related to the structural use of concrete in buildings and structures where the design and supervision of plain, reinforced, prestressed (by means of pretensioning or post-tensioning) and precast concrete are under the direct control of appropriately qualified engineers and technologists. It does not cover the structural use of concrete in piles, harbour and marine works, and underground works in mines. NOTE 1 This part of SANS 2001 is suitable for the construction of concrete work designed in accordance with the requirements of SANS SANS provides guidance on how to specify aspects of concrete works and how to comply with particular requirements. NOTE 2 This part of SANS 2001 may be used as an alternative to SANS 2001-CC2 to construct concrete works designed in accordance with the standard designs contained in national standards, for example, SANS and parts of SANS NOTE 3 Appropriate modifications to this part of SANS 2001 are required to extend the applicability to structures excluded from the scope of this part of SANS Normative references The following referenced documents are indispensable for the application of this document. All normative documents are subject to revision and, since any reference to a normative document is deemed to be a reference to the latest edition of that document, parties to agreements based on this document are encouraged to take steps to ensure the use of the most recent editions of the normative documents indicated below. Information on currently valid national and international standards can be obtained from the SABS Standards Division. ASTM C 156, Standard test method for water loss (from a mortar specimen) through liquid membrane-forming curing compounds for concrete. ASTM C 260, Standard specification for air-entraining admixtures for concrete. ASTM C 309, Standard specification for liquid membrane-forming compounds for curing concrete.
