“1.1 This code of practice covers recommendations for provisions to achieve and maintain cover over reinforcement in insitu reinforced concrete members that are subject to normal construction loads. Where appropriate, the basic principles can also be applied to precast concrete or proprietary systems. 1.2 The provisions in this code of practice apply to all types of reinforcement that comply with BOS 148 and BOS 149. 1.3 Other important areas such as clear and unambiguous detailing, the need for considering buildability, tolerances in formwork and reinforcement, have not been covered in this standard since they are covered in other standards and reports (see Bibliography). Good standards of workmanship and supervision have also been considered to be outside the scope of this code of practice. 1.4 Abnormal loads such as those exerted by construction plant, storage of materials and heavy reinforcement cages, can overload reinforcement cover devices (RCDs) and chairs at the spacings recommended in this recommended practice. Under abnormal load conditions, adequate support is achieved by using heavy category line RCDs at spacings that depend on the exact size and nature of the load.”

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.
