HI, the attached 649547a shows a single pipe penetration through a fire rated wall, however we were asked if there is a minimum distance between these pipe penetrations. can you confirm if there is?

Hello Carlos, Engineering Judgement 649547a is for a single penetration. However, if you have a case of multiple penetrations running through one opening, please submit a new Engineering Judgement request through the Hilti Construction Platform. If you have any additional questions about this Engineering Judgement, please email us your questions to cafirestop@hilti.com and we will get back to you through email.
