Steel Buildings in Europe

Part 7: Model Construction Specification 7 - 34  The material shall be poured under a suitable head so that the space is completely filled.  Tamping and ramming against properly fixed supports shall be used if specified and/or recommended by the grout manufacturer.  Vent holes shall be provided as necessary. Immediately before grouting, the space under the steel base plate shall be free from liquids, ice, debris and contaminants. If treatment of steelwork, bearings and concrete surfaces is required before grouting, it shall be specified in the contract documents. Care shall be taken that the external profile of grouting allows water to be drained away from structural steel components. If there is a danger of water or corrosive liquid becoming entrapped during service, the grout around base plates shall not be surcharged such that it rises above the lowest surface of the base plate and the geometry of the concrete grout shall form an angle from the base plate. If no grouting is needed, and the edges of the base plate are to be sealed, the method shall be specified. Anchoring devices in concrete parts of the structure or adjacent structures shall be set in accordance with their specification. Suitable measures shall be taken to avoid damage to concrete in order to achieve the necessary anchoring resistance. Foundations shall be adequately designed by a qualified foundation engineer to support the building reactions and other loads which may be imposed by the building use. The design shall be based on the specific soil conditions of the building site. 13.2 Interface to neighbouring constructions The mutual influence of neighbouring constructions for wind or snow actions must be carefully considered. Design wind and snow loads may vary considerably regarding the site and the construction environment, hence, precise indications shall be given, in the contract documents, concerning the surrounding constructions.
