Ok, folks - I'm a software engineer and if you think it's "hard to guess at a price for a covered porch" you ought to try to "guess at what I need for software for my business". Let me tell you this - if I ask you a few questions, I can give you a ballpark figure (and trust me - there's a hell of a lot more variables to building software than building a porch - I've done both). Why don't people want to speculate by asking a few questions? Because they are chicken. I stand behind my products and I can give you a "ball park figure" on any piece of software - tailored specifically to your needs - by asking a few questions.
I can also tell you that to build a covered porch out of pressurized wood in East Tennessee with basic building materials (like shingled roof attached to your existing structure) can run anywhere between $10 a square foot up to $40 a square foot - again with basic materials. You start adding costs when you upgrade to a copper roof and polished cement flooring - if you know what I mean.
don't be scared to offer educated suggestions, folks - that is, if you are truly educated. If you aren't how about you just not comment at all?
I "somewhat" agree with you.
However, I've yet to see any software that can have a failure and
result in "catastrophic" results -
(Not "BSOD"s or memory management problems)
Meaning - death or injury.
Yes; I know of, or have seen those results.
Most of us - don't like to make recommendations that may have, some
type of "structural", ramifications.
There are also, possible "legal" issues.
The "OP" should consult their local "Code Enforcement Entity" before they
come here and ask for opinions!
Got a plan??
Gonna pull a permit??
