Hi, is there a document that can help to prove and determine which part of the pre cast wall panel is cracked and non cracked concrete, we are installing punch windows and strip windows to reinforced pre cast walls, and we wanted to know if its cracked or non cracked. Any document like BBA or anything that can support this.
Hi Ahmed,
Thank you for your question, unfortunately there isn't a specific guideline on cracked/non-cracked nature of pre cast panels.
The best document to look at to help in this would be the guide from the Australian Engineered Fasteners and Anchors Council (AEFAC) technical note. The document can be downloaded from the below link:

Hope this helps,
Kind regards
