“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.”
