You could use the factor of safety in the North American Cold Formed Steel Specification. Page 101

I'm looking at an old flat roof framed with glulam and rough sawn lumber. The client wants to add an HVAC unit to it. It's sagging and ponding intermittently between glulams. The roof doesn't have drains or scuppers. Has anyone tried to reverse the sag to eliminate the ponding or should...

Check the data sheet to see the maximum depth of the repair sika recommends. Some grouts are too exothermic and will swell while curing, then shrink when they cool down. You can add a bit of aggregate to cool it down.

Look up at a cell tower. Most of the antennas are held the strucutre with ubolts and clip angles.

It should be the total area, you can split the rebar over both faces.

I have worked with thin stone veneer. I came across this handbook. https://www.indianalimestonecompany.com/technical-data/ili-handbook-and-technical-notes/ I have another book "Stone Cladding Engineering" by Rui de Sousa Camposinhos that has a modern approach in line with Eurocode. Try...

I had a situation where the contractor backfilled a lube pit prior to the floor going on over the pit. The contractor provided wood shoring that was completely outclassed. The wall bowed in a couple inches and the masonry overhung the exterior support wall. Looking back, I should have put the...

Do you have a link for that? Lots of these European based fasteners are coming into our market. It's driven by cross lam. I recently used a 45-degree washer to screw the top flange of a steel beam to the underside of an existing top plate. It saved me adding a nailer to the top of the beam. The...

Check My-ti-con. They're in Canada and sell to the USA as well. They have design guides and testing information for their products. I think all of these fasteners are from Europe.

I was at a seminar where some new wood fastener techniques were being explained. Its possible to reinforce wood with screws when loaded perpendicular to the grain. Link to My-ti-con Paper

I've run into this a few times on retaining walls and on guards at slab edges. A better practice is to use a flush plate with embeds. You can weld to it later. A side mounted plate for retaining walls is also good.

Aluminum design is such a bear at times. In Canada,they just last week added a CSA standard for aluminum design to follow that includes screws . I have tried to put together a proper spreadsheet on previous jobs but the situation becomes so specific that I can't reuse it.

As a common courtesy you should call the architect and mention your involvement. You should be objective with the other professional. You don't know if there are other lateral resisting systems added during construction that aren't shown on the drawings. I think it's one of the most basic...

First guy in the ground and last to get the information. Draw a picture of the loading scenario assumptions and stick it right next to your stamp.

I've been asked a few times for help with this sort of thing. It needs to be checked against all the environmental loads that it's subjected to. Use judgement for deflection, maybe use the limits of signage. You can check the structure for the loading of a person climbing it. That might be...

Draw a picture of the cross section and show the couple. The friction factor is a tough call sometimes. I've seen dents left by Ubolts installed as antenna mounts.

I work in Canada. I have to purchase the electronic certificate from a not-for-profit in Quebec. It costs me $180 per year. The certificate pings my licencing board anytime a digital stamp is validated by opening a drawing. Its been two years since I used a wet stamp. I submit all my drawings...

This appears to be similar to the Cat S60 smart phone. The cat phone is $700 USD and runs a more modern version of android. It also has software to stitch the thermal image to an optical image. I have a thermal camera from Seek Thermal. It's handy for locating the structure behind finishes. One...

I really sympathize with your situation; I always feel my liability looming around like a dark cloud. You're liable for your comments and participation in your friends problem. A good lawyer could pin it to you. I doubt your friend would do that even if they are currently mad. It's a crumby part...
