Regulations for electronic construction accounting
The regulations for the electronic construction accounting (REB) describe the calculation methods and methods for exchanging data for quantity determination.
Quantitative bases are determined as mathematically correct (payment reasons for invoices) determinations that justify payment. Source of supply is the homepage of the BAST (Federal Highway Research Institute).
The publisher for the well-known REB 23.003 is the Federal Ministry of Transport and Digital Infrastructure (BMVI). Until 2013 it was the Federal Ministry of Transport, Building and Urban Development (BMVBS).
There are GAEB process descriptions for the Joint Committee Electronics in Building , which are assigned to the Federal Office for Building and Regional Planning (BBR).
The following GAEB / REB process descriptions are available:

REB-VB 23.003
The REB procedure description 23.003 has also been introduced and known on the market since 1979 under the term “general construction accounting”. In addition to the description of the structure of the exchange file DA11 , the accounting procedures and calculation methods are described.
The formula collection of REB-VB 23.003 consists of 25 or 26 (edition 2009) different formulas. The best known of the REB-VB 23.003 formula is the "Formula 91" - also known as the "Free Formula". With it, a mathematical approach such as B.
- "4 * (3.45 + 2.34 + 4.12) * 2.45 * 0.365 ="
be turned off. The formula 91 can extend over a maximum of 6 or 20 lines (each with 38 characters). An equal sign is required after the values .
Another well-known formula is the formula 04 (or 4) for a rectangle or a cuboid. Formula 04 is also an example of the formulas that can be used to calculate areas and volumes. Depending on the number of input values, an area (formula 04 with 2 values) or a volume (formula 04 with 3 values) is calculated.
Further development: In summer 2009 the REB 23.003 edition 2009 was presented. Requirements from the market have been updated in the existing REB 23.003 (harmonization). The VB bears the name “General Quantity Calculation” REB-VB 23.003 Edition 2009. The ordinal number has been adapted to the requirements of GAEB 90. GAEB DA XML 3.2 was released in October 2013. The X31 is included in this GAEB regulation. This means that quantity take-offs from REB 23.003 can be exchanged. The advantages u. a .: Long ordinal numbers are allowed (not just 9 digits, but up to 14 digits) and the exchange file is a modern XML file. In addition, catalog information on the quantities can be exchanged.
