Steel Buildings in Europe

Part 7: Model Construction Specification 7 - 30 Areas of supports that require protection against rust staining shall be identified and appropriate protection provided. Compensation for settlement of supports is acceptable, unless otherwise specified in the contract documents. This shall be done by grouting or packing between steelwork and support. The compensation will generally be placed beneath the bearing. Shims and other supporting devices used as temporary supports under base plates shall be placed in accordance with the requirements of § 8.3, 8.5.1, 9.5.4 and 9.6.5.3 of EN 1090-2. Grouting, sealing and anchoring shall be set in accordance with their specification and the requirements of § 5.8, 9.5.5 and 9.5.6 of EN 1090-2. Components that are individually assembled or erected at the site shall be allocated an erection mark, in accordance with the requirements of § 6.2 and 9.6.2 of EN 1090-2. Handling and storage on site shall comply with the requirements of § 6.3 and 9.6.3 of EN 1090-2. Any site trial erection shall be performed in accordance with the requirements of Clauses 6.10 and 9.6.10 of EN 1090-2. The erection of the steelwork shall be carried out in conformity with the erection method statement and in such a way as to ensure stability at all times. Foundation bolts shall not be used to secure unguyed columns against overturning unless they have been checked for this design situation. Throughout the erection of the structure, the steelwork shall be made safe against temporary erection loads, including those due to erection equipment or its operation and against the effects of wind loads on the unfinished structure. At least one third of the permanent bolts in each connection should be installed before that connection can be considered to contribute to stability of the part completed structure. All temporary bracing and temporary restraints shall be left in position until erection is sufficiently advanced to allow its safe removal. All connections for temporary components provided for erection purposes shall be made in accordance with the requirements of EN 1090-2 and in such a way that they do not weaken the permanent structure or impair its serviceability. If backing bars and draw cleats are used to support the structure during welding, it shall be ensured that they are sufficiently strong and that their retaining welds are appropriate for the erection load conditions. If the erection procedure involves rolling or otherwise moving the structure, or part of the structure, into its final position after assembly, provision shall be
