Type of Standards


This International Standard can be used as an alternative to the development of a National Concrete Bridge Design and Construction Code, or equivalent document in countries where no national design codes are available by themselves, or as an alternative to the National Concrete Bridge Design and Construction Code in countries where specifically considered and accepted by the national standards body or other appropriate regulatory organization, and applies to the planning, design and construction of structural concrete bridges to be used in new bridges of restricted span length, height of piers, and type.
The purpose of these guidelines is to provide sufficient information to perform the design of the structural concrete bridge that complies with the limitations established in 6.1. The rules of design as set forth in this International Standard are simplifications of more elaborate requirements.
Although the guidelines contained in this International Standard were drawn to produce, when properly employed, a structural concrete structure with an appropriate margin of safety, these guidelines are not a replacement for sound and experienced engineering. In order for the resulting structure designed employing these guidelines to attain the intended margin of safety, this International Standard must be used as a whole and alternative procedures should be employed only when explicitly permitted by the guidelines. The minimum dimensioning guides as prescribed in this International Standard replace, in most cases, more elaborate
procedures such as those prescribed in the National Code, and the possible economic impact is compensated for by the simplicity of the procedures prescribed here.
The professional performing the structural design under these guidelines should meet the legal requirements for structural designers in the country of adoption and have training and a minimum appropriate knowledge of structural mechanics, statics, strength of materials, structural analysis, and reinforced concrete design and construction.
Designs and details for new bridges should address structural integrity by considering the following:
– the use of continuity and redundancy to provide one or more alternate paths;
– structural members and bearing seat widths that are resistant to damage or instability;

The Botswana Bureau of Standards (BOBS) understands the importance of impartiality and confidentiality in carrying out its management system certification activities. BOBS management is committed to gaining and maintaining the reputation, credibility and ultimately, confidence of its stakeholders in rendering its certification services. Additionally, BOBS strives to continuously manage foreseen potential conflicts of duty and interest and ensures objectivity of its activities under the management system certification. To achieve the above, BOBS shall identify, analyse, record and manage potential conflict of duty and interest to ensure that certification services are not provided within relationships that have been identified to pose an unacceptable threat to impartiality. An Impartiality Committee shall periodically review activities of the certification function to verify commitment to credibility and fairness. The Committee shall further assist in the development of policies relating to impartiality of providing certification activities. BOBS is committed to maintaining in strict confidence all information accessed while rendering the certification services and shall ensure that such information is not divulged to third parties without the Client’s written consent unless if required by law.
Demand Quality

When things don't work as they should, it often means that standards are absent.
