1) New wooden bookshelves are bowing and detaching from the strut underneath which is then attached to the wall. The shelves need to be strong enough to hold wine racks with wine, academic books and especially art exhibition catalogues - heavy books.
There are 8 short shelves, one of which has already broken with the weight of the art books; and 2 long shelves (2.5m). All need reinforcing.
2) Remove 2 shelves of approx 55cm long from the wall; reduce the length by approx 3-4cm (to be confirmed); reattach to the wall with reinforcements.
3) Make and paint a 3rd shelf approx 114cm (L) x 25 - 30 cm (W); attach to wall with reinforcements.
Please confirm earliest dates you could do this work, especially Part 1.
