This Manual is a working document for concrete reinforcement that can be used to interpret the designer’s instructions in the form of drawings and schedules for communication to the construction site. The information given is essential for both the designer and detailer — and both parties are responsible for ensuring that they are working with correct information, particularly as the designer is likely to be just one component of a wider project team.
The information and guidance is based on Eurocodes and UK practice but considered relevant for use in most parts of the world with only minor adjustment. The purpose of this Manual is to provide a standard reference that can be used by practising designers and datallers, as well as being a valuable teaching aid for more junior engineers. It uses 'Model Details’ (MDs) to illustrate the preferred method of detailing for each type of structural element (Chapter 6).
It is assumed that it is the designer’s responsibility to specify design requirements clearly to the detailer — and the detailer’s responsibility to implement these requirements in a consistent, unambiguous and complete way, for the end user. Certain details have design implications, and this guidance does not attribute a lesser degree of responsibility to the designer. In detailing reinforcement for structural concrete, the impact on the entire project team should be borne in mind; poor detailing can lead to other issues/additional costs at a later stage.
The term 'standard method’ should also be clarified. It is not intended that any one detail should be copied verbatim for all situations, but all the principles should be followed. Details can be prepared with different objectives in mind, e.g. to reduce labour on site by allowing off-site prefabrication of reinforcement into cages, or to utilise the materials most readily available in a particular location — the principles covered in this Manual apply to almost any objective.
The details have been prepared with the following priorities in mind:
• technical correctness and safety
• buildability and speed of construction
• labour and material costs
The previous (third) edition of this Manual (2006-20) introduced detailing rules that conformed to the current version of principal standards at that time, which remains the case for this edition:
BS EN 1992-1-1. Eurocode 2. Design of concrete structures. General rules and rules for buildings
BS EN 1992-1-2. Eurocode 2. Design of concrete structures. General rules. Structural fire design 2
BS EN 1992-2. Eurocode 2. Design of concrete structures. Concrete bridges. Design and detailing rules'3
BS EN 1 992-3. Eurocode 2. Design of concrete structures. Liquid retaining and containing structures 4
It should be noted that UK National Annex values are embedded in the equations and tables. In general, the conventional use of materials covered by European Standards or British Standards is assumed. Where other authoritative documents exist, this Manual refers to them rather than repeating them in full. It refers to generic rather than particular proprietary systems — and any proprietary systems shown are for general illustrative purposes only and are not specifically endorsed.
