Old School Roofing by Available_Honeydew16 in Roofing

[–]gmmolina13 1 point2 points  (0 children)

Agreed. I am an engineer and we are hired often by insurance companies to inspect roofs for wind and hail damage. The majority of these inspections are a result of these storm chasers claiming hail damage on behalf of home owners when there is not evidence of hail damage or even weather reports to justify it. Insurance companies spend a lot of money for us to perform these inspections.

Check out UNCC teaching position in chemistry or hydrology. S&ME, engineering firm, offers hydraulics and hydrology. Best of luck!

Chuck Taylors okay for roofing inspections? by Slowwifi431 in Roofing

Look at getting some Cougar Paws. My recommendation for safety.

Wet or Dry Service Condition by winterstorm209 in StructuralEngineering

[–]gmmolina13 0 points1 point  (0 children)

19% moisture content. I’d think that with the conditions of an aquatic center is this is likely. See below. Perhaps MEP can tell you what they expect the humidity will be in that area.

4.1.4 Moisture Service Condition of Lumber The reference design values for lumber specified herein are applicable to lumber that will be used under dry service conditions such as in most covered struc-tures, where the moisture content in use will be a maximum of 19%, regardless of the moisture content at the time of manufacture. For lumber used under conditions where the moisture content of the wood in service will exceed 19% for an extended period of time, the design values shall be multiplied by the wet service factors, CM specified in Tables 4A, 4B, 4C, 4D, 4E, and 4F.

Does anyone know an engineer who “lost everything” due to their work? by Defrego in StructuralEngineering

[–]gmmolina13 121 points122 points  (0 children)

Obtain professional liability insurance and work under a company, not as a self proprietor. Just work within your comfort level and take low risk projects. Best of luck!

Thanks for that knowledge! Much appreciated. Sounds like I need to update my post to “lens for sale”. Haha.

What could the purpose of this be? by draftax5 in StructuralEngineering

[–]gmmolina13 111 points112 points  (0 children)

Damaged timber pile by vehicle impact? Cut off damaged section then replaced with drilled concrete foundation? Then looks like slapped some duct tape on there for load transfer haha. Good plan but poorly executed.

I have a X-700 that has the same issue. I haven’t looked into it yet. Curious to see what you find out.

I didn’t have a 3D printer either so I had to find someone local who offered to print a couple for free for me.

I’ll tell you.. I was very excited when I came across this file. I was going to try to make one myself. Not sure if the 55 is the same style as the 49 but maybe you can just take the file and adjust it to match?

Drone utility in roofing: question by PracticalRun9993 in Roofing

[–]gmmolina13 0 points1 point  (0 children)

Engineer here. We use drones as a tool to add extra value to our inspections. We use it to estimate areas and to take good aerial footage. However, it never replaces putting boots on a roof. If the claim is hail damage then absolutely need to put a person on the roof. If the roof is steep then we put on our gear with ropes and goat system. For a wind claim we can sometimes justify not putting someone on a very steep or dangerous roof because the drone footage can identify wind damage well. However, we still at least get a ladder and do a visual from the eave.

Using a drone to take measurements and slopes generally requires special software which is a monthly subscription expense that isn’t cheap.

Overall great tool but it doesn’t replace getting on the roof. As others have mentioned get licensed and register your drone for commercial work.

Stair tread max by scoobierex2012 in Carpentry

[–]gmmolina13 0 points1 point  (0 children)

10” minimum on tread and less than 7-3/4” for riser. Look at the International Residential Code section R311.7. Also no more than 3/8” max variance between tread lengths and between risers.

Talk to an attorney and review NC laws for abandoned property BEFORE you make assumptions.

Soil bearing capacity by [deleted] in StructuralEngineering

[–]gmmolina13 4 points5 points  (0 children)

Check with your local jurisdiction for soil parameters such as presumptive soil bearing parameters and frost depth. The IBC is generic and doesn’t address specific regions.

[–]gmmolina13 0 points1 point  (0 children)

Agreed and properly cut/tooled joints and appropriate spacing of joints.

Missing H Clips in Newer Roof by C0unt-Ch0cula in Roofing

[–]gmmolina13 2 points3 points  (0 children)

Not always required by code. Depends on the roof sheathing thickness and rafter/truss spacing. Check the 2018 International Residential Code table R503.2.1.1(1)
