I can help
Let me read closer
I can help you with the sizing of the lintel, but I can't provide any details for this value.
Just let me know if you're still interested.
Before we get started I’d like to point out that a Professional Engineer’s standard of care typically includes a site visit to assess field conditions and get an overall understanding of the structure. This can obviously not be accomplished through the internet. The information provided here is meant for informational purposes only (general sizing and budgeting) and is based on the information provided by you. The information should be verified by a professional engineer who can visit the site to ensure that potentially important information has not been overlooked or omitted.
yes still interested
Can you tell me a little more about the structure?
What is the length of joists on each side of this wall?
Does it only support that one floor?
What is the height of the block above the opening?
If you let me know this, I can get you an answer quickly.
