I would find the function very helpful and for us in the office it would make it much easier to calculate the offer.

In addition to the fact sheet 51 'Urban Planning Design', there has also been the fact sheet 52 'Open Space Design' for not too long.

In fact, this shouldn't be all that complex when creating a fee calculator, as with all other HOAI services, the fee is calculated using service phases and associated table values (here, however, as an estimated hourly expenditure and not as a fee value).

Hi Inga, that's right. With AHO No. 42, the various services such as master, framework plan, etc. can now be calculated in a differentiated manner.

As far as I know, leaflet No. 51 has been replaced by AHO publication series No. 42 (so-called Green Issue) “Special Services for Area Planning Annex 9 No. 1-5 HOAI 2021 Focus on Urban and Urban Development Planning (Part 2 Section 1 HOAI 2021)”.

ISBN 978-3-8462-1392-6

Does anyone know more about this?

Is AK Baden-Württemberg the author of the leaflet 51? - Is this available royalty-free? Does anyone know that? projo would definitely have to check with the author, as this is obviously not a text of a regulation.

I would find that very helpful!

This calculation aid would also create an additional sales argument for urban planning offices and landscape architecture firms.
