Agreed, but the issue remains as under the rules here in Alberta virtually anyone involved, except the officials, is held responsible thus is there a potential for an engineer to be held liable if designing for non-complaint manufacturers ? I suspect we will see litigation arising from some of...

In Alberta where I am, steel building systems are governed by the Alberta Building Code of course which does require an engineers' stamp and the A660-10 certification of the manufacturer. There are lots of manufacturers who ignore the A660-10 certification yet continue to sell their products...

Here's a link to the CWB outline of A660-10 http://www.cwbinfo.org/sites/cwbinfo.org/files/downloads/OPSBooklet_ManufacturersOfSteelFinalOnline.pdf Bob MBC International Pre-engineered Building Systems

My original question was about engineers designing or stamping for a company which does not have the A660-10 certification, which assumes the engineer knows the client - employer does not have it. Why an engineer would not know about A660-10 which has been around for more than a few years is...

Yup, think you're right ! Bob MBC International Pre-engineered Building Systems

The buildings I have seen were mostly Chinese in origin and don't even come close to meeting codes but a lot were also manufactured by local companies who refuse to get the A660-10 certification claiming it's just another cash grab by the certificate issuing authority which is the CWB here in...

The issue is the designing or stamping of structures for manufacturing companies that don't have A660-10 as required by code. It is a requirement both in the NBCC and virtually all provincial codes that all prefabricated steel building manufacturers, including fabric covered buildings, have the...

Is there no identifying name plate anywhere on the building ? Not too many companies left that make these and likely the manufacturer of that building is out of business unless it is western archrib. Bob MBC International Pre-engineered Building Systems

where is it located ? Bob MBC International Pre-engineered Building Systems

Would anyone care to hazard a guess as to what the potential risk might be to an engineer who designs or stamps pre-engineered building systems for manufacturers that are not A660-10 certified as required by the NBCC and all the provinces in Canada ? I ask because we are seeing a lot of fabric...

Hi All: I am looking for a supplier who has a lag screw for driving into wood that also has a thin washer style collar just above the threads with a solid steel shaft above that. Am looking for 1/4" up to 3/4" diamater by 1" up to 6" long. Any manufacturers out there that have these ? Thanks...

Would it not be simpler to use stucco coated cladding ? Lots on the market... Bob MBC International Pre-engineered Building Systems

Can I ask if the geotechs included any geo fabric in their design under the fill ? Is the clay under the fill material what ws there to begin with and if so what sort of composition or is it part of the fill plan and thus "clean" material ? We have seen record rainfalls in western Canada in...

Hi: We do indeed do good work, too bad the economy has bumped everyone and projects the way it has. Like everyone we are only at about 50% capacity with so many jobs evaporating. We warranty our workmanship unconditionally for 1 year and can say we have never had a warranty claim yet. As well...

You're aboslutely right, this is thier design and their building system. One thing I do understand too well is liability and responsibility. That's why I take steps to cover "due diligence" amd document it all. I undertake the erection of their building package stamped by their engineers and...

Thanks for the compliment. I have been at this for 30+ years and have seen a lot of different approaches to building design, some good, some just plain silly... This design does seem able to handle heaving but my concern, even though a small hoist lifting a max 1,000 lbs the potetial for...

I know that the winters are sufficiently cold in that area to drive the frost down very deep so it may be slow coming out in the spring time but coupled with moist soil conditions it is definately going to be a concern. Mind you, I have concerns about the whole foundation - crane system...

Hi: The nature of the site mats is that they are 8' x 40' and 3 layers of 3" thick oak plank fastened together. The mats are tied to each other. No insulation is allowed on site. they just go in flatten the ground surface then lay these mats down and that's it. Bob MBC International...

Hello: I apologize in advance if my description is confusing: I have a customer who wants us to erect a 50' x 325' x 18' arch shaped fabric building for them which has a concrete ballast block foundation system 4' high x 325' on one side (back wall) and each 50' end as the building has to be...
