guys i have a 20ft load bearing wall in the basement and a 2 storey house - so i have basement on slab, floor 1 and floor 2 and a roof. house is 3550 sq ft.

We need it removed to open up the basement for a kids play area.

Contractor says he can do it with 2 vertical posts and 1 horizontal - 24 ft header beam (6,4x24) - all wood i.e

I am contemplating calling in a Structural Engineer to bless it. What pricing do i need to look for. I live in GA, Atlanta area.

Any suggestions . Also is a metal header beam an option ?

I need to keep costs in check but i also don't want to be foolish.

I can provide pics if needed.

Please share your thoughts.

I would have it engineered.Steel is and options and would take up less ceiling height.
thanks that was quick - what are the approximate price comparisons between steel and wood. How do i go about getting steel quotes, cost, delivery etc etc... seems heavier than wood right ?

thx again.

remove 20 ft load bearing wall.

steel will be more expensive. getting an engineer on this one would be a safe move. :thumbsup: dont know about price. youll know price when you find out what the engineer or architect says.

Without your location it's hard to say.If your in a larger city some of the steel fab shops will have an in house engineer.Depending on the wall thickness of the beam you'll be able to pick up some headroom.They do deliver and yes,they are heavy and will need to be jacked into place.Not a big deal.They will need to weld some mounting brackets on the ends that will be speced by the engineer.

Thanks all .. i know I'm doing the right thing to go with the Engineer.

Is the 20ft opening not out of the ordinary right. ? there is no minimum distance by which i have install vertical posts ?

Also seeing alot of individuals glue 4 pcs of 1-3/4 x 6 x 24 LVL together to form a 7x6x24 LVL .. this will be a bit more work but i can save some money on transportation and logistics.

Wondering if any of you have pros and cons on this approach as well.

thanks.

Pictures are not going to do any good on this one.
Need a real engineer on site specking the material, sizing, and footing design.
No clue what "beam (6,4x24)" is suppose to mean. 4 X 6 X 24?
No way would I be using solid lumber like that as a horizontal beam.

Depending on the load---20 foot could be one free span beam without any posts--or might need one center column--

Your engineer will be able to figure out what is best.

The height of a beam has a lot more to do with the strength of it than the width. Depending on the load above I don't believe this proposal would have sufficient strength to span that distance. When you get engineer to look at it can give you options both ways, either steel or multiple LVL beams. Given that it should be very easy to figure out the most economical approach.

Got the recommendations back from Engineer :

4 x 1 3/4 x 16 x 20 LVL beams and to sipport these colums of 4x4 tubular steel column 1/4 inch thick with 8 in. x 8 in. 1/2 in. steel top plate and bottom plate

FYI. thank you.
