Hi All, Maybe my google FU isn't what it used to be, but I can't seem to find any real information regarding an old PEMB I'm working on. This is a true PEMB off the shelf type item. From what I can tell it's from Inland Ryerson Building Systems (potentially also called Inryco). My frames are...

Do any of you wonderful sources of information have some super ballpark type costs for heavy timber construction and/or CLT. Situation: Multi-story office building located central Canada. No layouts yet, still trying to choose systems. If you even have some numbers from a local project we can...

House Moving Failure I'm surprised we don't see this more often. I've watched that show Massive Moves a lot, the guys doing the moving are just a bunch of cowboys typically.

Hey all, Anyone have any info on 18" TJI joists from the mid 90s? Anything you've got would be muchly appreciated by a colleague of mine.

Hey All, (Likely Josh) I've created a reinforced w-column using RisaSection, it calculated all the properties correctly (from what my quick hand check suggest). We are adding plates to the flanges to keep the shape symmetrical. I've also successfully imported said section into R3D including...

RISA does not do concrete wall design to CSA correct? If I'm reading the release notes accurately, it only designs walls for ACI.

Hey all, One of the guys in the office here went to site and measured up some existing steel deck. It has similar material thickness and flute widths and flute spacing to standard 1 1/2" deep steel deck however it is only 5/8" deep. Does anyone here have some info on anything like that? If it...

Gents, Seems like a basic question but I'm going to ask none-the-less. I've got a current situation where a set of granite stairs is supported by steel framework. The steel is about 4 years old and is already showing significant surface corrosion. Generally this steel is enclosed in an...

Hey all, I performed a bit of googling but couldn't find what I'm after. I've got an existing warehouse from the mid '80's that has 4" coldstream wall panels on the exterior. Anyone have a weight on these panels? They're some form of pre-cast insulated panel. I could just call them 4"...

A couple of us in the office are having a debate regarding shoring and I'm looking for more opinions. Back story, there's a ton of shoring going in at a WWTP to facilitate expansion. The existing buildings (let's call grade elev. 100') are on driven piles with average t/o pile cap at elev...

Hey All, CISC has asked our firm (and many other I'm assuming) to send them some suggestions for research. They will provide grants to students who choose to research CISC's approved topics. Since some of you have not received this request I am putting the question out for you to have your...

Hey everyone. I have this steel roof truss comprised of double angles for all members with a 10' bay spacing for the bottom chord and verticals at the intermediate 5' marks for the top chords. This truss was designed and constructed in the late 60's under Canadian design standards. I've...

Hello everyone, I have a new job on my desk to analyze an existing fall restraint system to see if it has the capacity to support more load, they want to be able to use it as an equipment hoist at the same time. The existing drawings call off a Spanco 600 track for the trolley to install in...

Josh, Any chances RISA is looking into expanding their training sessions into Canada? Is there anything at those training sessions I couldn't learn from webinars and practice? Thanks, P.S. settle a debate for me at the office. How is the name RISA intended to be pronounced. I was originally...

Hey all, I've got a couple of sizeable rooftop units going on a fairly large building. By the numbers I need to account for build-up but that causes failure of the entire system basically (deck, joists, beams and columns). If I only need to account for unit weights then the beams and columns...

Hey all, We've been contacted by a potential client that uses circular cages with steel plate surrounding it as shoring for hydro vac services. These cages are approximately 5 feet in diameter and are constructed in 40" tall segments. These segments are then connected together to form whatever...

Good Morning All, Got a question for all of you. Why are all fasteners into treated lumber required to be galvanized or stainless besides the moisture aspect? Do the chemicals used to treat the lumber cause problems for standard nails/screws? I've never had a need to know why I've just always...

Hey guys, Just got a request from a supervisor to get some reading materials on designing dome housing. I'm looking for some guidance from anyone that has done these on some places to start and detailing to pay close attention to. We haven't had the meeting with the client yet so the actual...
