Pre-engineered Metal Building Collapse in California
(OP)
Is anybody aware of a 160' clearspan pre-engineered metal building which collapsed while being erected in California? Recently.

Is this what you found on the web?
Collapse date: May 3, 2017.
Location: Riverside, CA west of I-215 on Meridian Parkway
I did a quick check of CalOSHA and did not see any citations (that often describe the building type/spans/configuration in detail) but such investigations usually take some time.

Assuming my post above is the project your refer, here is some additional info:
Facility: Existing was 110,000 SF. 2017 expansion was 60,000 SF.
General Contractor: LEDCOR Group for 2017 expansion.
Based upon some photos of the collapse, I figure some 'rough' estimates that the expansion was 1 new interior frame (welded plate girder) and 1 end frame (with wind columns). Frame spacing may be 30-35 ft (?). Orthogonally, about 6 or 7 bays of 25+ foot spans, so that makes a width of somewhere around 150 ft.
No info on who the PEMB manufacturer was.
Here is a Google Earth 3D view of the site from 2017 during foundation works. Scaling, the plate girder span is 152 ft.

That is indeed the building I found. Thanks for the additional information. This site is extremely valuable and useful for all things structural. I will post additional information as I find more out.

You are welcome.
I should have posted my sources, so here they are: Link and Link
Is your interest in this collapse based upon professional curiosity, or some research/other you are undertaking?
Keep us all informed on what you discover.
RE: Pre-engineered Metal Building Collapse in California
Professional curiosity is my main interest. I work for a general contracting firm that primarily puts up pre-engineered metal buildings as well as conventional construction projects. So I am always interested in additional information about why buildings don't work. The building manufacturers are generally pretty tight lipped about why a building had problems, so if you want to learned what caused the problems you have to research the problems very diligently.
Thanks you for the additional information and pictures.
