Re: Berkeley Balcony Collapse

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Fellow engineers,

        Please excuse my interference here.

Has anyone considered the option of requiring ALL cantilevered balconys to be fully exposed from the underside? This would allow all structural components to be inspected continuously. After all, all structural materials, except exotic ones like stainless steel, will eventually corrode given the right exposure and enough time.

Regards,

Daryl

On a related note. I asked what you guys spec for exterior plywood decks and got 2 responses.
APA:
"This email is being sent to you in response to your inquiry regarding the need for pressure preservative treated plywood in outdoor decking for pedestrian and vehicle parking structures. As noted in the attached documents if the plywood is protected from moisture preservatives are not required. However, should the moisture protection fail the use of pressure preservative treated plywood will protect the structure from decay."
Well Duh.

and Andrew's suggestion of Marine Grade ply--better quality core but not decay resistant.

Anybody else have something?

Shocking that a developer thinks hang steel is an unnecessary expense
