Bs8666 Shape Codes

Shape Code 99
All other shapes To be calculated See Note 2.Where standard shapes cannot be used.No other shape code number, form of designation or abbreviation shall be used in scheduling. A dimensioned sketch shall be drawn over the dimension columns A to E. Every dimension shall be specified and the dimension that is to allow for permissible deviations shall be indicated in parenthesis, otherwise the fabricator is free to choose which dimension shall allow for tolerance.Shape Code 32A +B +C +(D) -1.5r -3dNeither A nor (D) shall be less thanP in Table 2.
The dimensions in parentheses are the free dimensions. If a shape given in this table is required but a different dimension is to allow for the possible deviations, the shape shall be drawn out and given the shape code 99 and the free dimension shall be indicated in parentheses.The length of straight between two bends shall be at least 4d, see Figure 6. Figure 4, Figure 5 and Figure 6 should be used in the interpretation of ending dimensions.
The length equations for shape codes 14, 15, 25, 26, 27, 28, 29, 34, 35, 36 and 46 are approximate and where the bend angle is greater than 45, the length should be calculated more accurately allowing for the difference between the specified overall dimensions and the true length measured along the central axis of the bar. When the bending angles approach 90, it is preferable to specify shape code 99 with a fully dimensioned sketch.
Stock lengths are available in a limited numer of lengths (e.g. 6m, 12m). Dimension A for shape code 01 should be regarded as indicative and used for the purpose of calculating total length. Actual delivery lengths should be by agreement with supplier.
Would anyone know where I can download a bending schedule template for BS8666-2005? I need one which would allow for editing of company logo, project details etc. and would also display Page numbers (1 of 5).
For the second part of your question about "shape code image generator": this website has all shape codes with all details and required data according to BS 8666 and BS 4466 so it will be very useful to you:
If you need to schedule setting up. I presented a class at Autodesk University a few years back. Take a look at the class and there are a few downloads of the files I used. Everything is setup in there.
Something to bear in mind. You can use the of the box reinforced detailing tools to good effect if you set Revit up. Yes it may take a little bit longer but you have full control of have things work and look. Not saying that you cant do this in SOFiSTiK or others to that matter.
Unfortunately my employer doesn't want to purchase any extra rebar software since we already have CADS-RC for AutoCAD. I'm setting up the office standard for Revit and would like to utilise all aspects of it. The poster above was very helpful in giving me a template for bending schedules. All that's left to be done now is customising the rebar tags and finding a way to 'tick and tag' bars which overlap, which I don't believe Revit does.
I work for a semi-state company and the procurement department requires you to show the work for which any new software is needed. Very narrow criteria. It took around 3 years to convince them to purchase CADS-RC. I'm really surprised they purchased Revit at all.
In January 2021, the British standard used to describe the scheduling, bending, and cutting of reinforcement bar was updated. The previous standard was BS8666:2005 and this forms the basis for the standard shape codes that ship with Revit. There are quite a few significant changes which affect how the total length of bars are calculated as well as some additional shape codes and updates to the bending schedule. Below you can see the new shapes added to the standard.
Here at Symetri we have created a full library of rebar shape families along with formulae that comply with the new updated standard. Additionally, we have added extra parameters to enable the scheduling of weights and control over shape codes.
This template comes free of charge when you book onto our scheduled 1-day RC detailing course or when you buy a licence of Naviate Accelerate or Structure. As a special promotion, we are currently offering this one-day course for 150 per person. Click the link to find out more about our 1-day course and book!
