Question Wall curvature (between wall & floor) as required by GMP

Happy New Year Everyone!

It seems that am back again, starting fresh again, hope all of you are not yet 'bored' to entertain my 'green' questions.

I'm new to GMP & civil engineer. I learnt that in building wall in compliant to GMP, it can't be 90 degree bent, instead it have to have a certain curvature for easy cleaning.

I googled (but it seems like am not entering the right keyword), but couldn't find 'wall curvature requirement in compliant to GMP'. I want to know what is the required radius for the curvature.

Any advice is highly appreciated. Thank you very much in advance.

Re: Wall curvature (between wall & floor) as required by GMP

The sharp 90 degrees joint between the wall and floor collect and retain dust and could possibly trap bacteria or others. Any radius/smooth curve that could practically be constructed will do. Also note that a porous wall or floor is also a no-no.
Thank You to harry for your informative Post and/or Attachment!

Re: Wall curvature (between wall & floor) as required by GMP

There is no specific cove standard to my knowledge. As Harry mentioned it it to prevent the build up of dirt in the corners so what ever you feel is suitable.

Re: Wall curvature (between wall & floor) as required by GMP

We are also constructing a new "clean" room. From everything that I have been told, the cGMP question is not what are the angles of the floor to wall but how do you show that the environmental conditions (viable and non-viable) meet the requirements of your product. I have yet to have an inspector ask about the angle of the floor to wall, they have asked to see objective evidence that the room meets product requirements and it is under control (monitoring). With that said, there are initial minimal room requirements if you are claiming a Certified Classification.

Re: Wall curvature (between wall & floor) as required by GMP

I know, I posted the question & I found the answer :

According to NZCP 6 Ed 1992 under section Design, Construction and Layout of Floors, the minimum radius of 25 mm in acceptable although other minimum radii may better suit the proposed building.

Re: Wall curvature (between wall & floor) as required by GMP

Thanks for the update, I was not aware that this specification existed. It certainly makes for a good future reference.
