Customer Question
Help! A main beam...

Help! A main beam, that was installed a foot too short and had an extension added, has just sank half an inch in our new build home. Not just the extension (which supposedly followed the 1/3 2/3 rule & had simpson supports in place among the manufactured wood extension), but the entire beam! The builder's fix was to lift the beam with a jack and put a single 3/8" OSB shim under one end. If the beam sank (not to mention the entire corner of the room above sagged down), doesn't that imply that there is an issue that goes beyond just the corner? AND won't an OSB shim possibly slowly compress over years and the house will follow? SHould have been steel, and probably should have remounted some other fasteners, yes? Also, all the stucco and drywall was already on- ALL of that is compromised already with drift- cracking and crumbling, especially because the first time they tried to jack it up, the jack slipped and the whole upstairs shook! Should we run, not walk, from closing on this house? I foresee years of issues that go well beyond the typical settling of a new house... Thank you for any advice!!!

Tutor's Assistant: OK. Is there anything else important you think the Structural Engineer should know?

When the beam was first put in, the framers took (4) 2"x6"s, hammered them together into a box and nailed it to the end of the beam as if that seemed structurally sound to them. ONLY AFTER we pointed it out did the builder engineer a fix. They said it would have been caught on inspection, but I doubt it since the framers were already covering the ends with ply-board. It all would have been covered for inspection.

Hi!
Customer reply replied 11 months ago
Here is fine. A phone call will require me to take notes so this is easier. How are you?
Customer reply replied 11 months ago
I am already losing $13,000 to a shoddy builder, should I chalk this up as just another loss? I do not wish to pay even more for a phone call. You guys emailed me that there is an answer....... anybody there? hello? Most stressful year of our lives. Please don't add to my list of regrets.

How was the extension of the been added to the beam? And how long ago was it done?

this was what they had just discovered when I showed up last Wednesday- then they started cutting everything open. Did not consult with engineer befor just ***** *****fting & shimming the beam... did it all on the fly...
Structural Engineer: StructuralEng, Consultant replied 11 months ago
I'm looking through all the documents that you posted now, so give me some time to look through them. For the very first one that you posted where it's attaching the short beam to the cripple wall, can you take a picture of this condition in your basement for me or describe where the support exists exactly?

Customer reply replied 11 months ago
No basement. The beam is the one in the photo between the garage and corner of second story cantilever. Once you see all pics it should be clear
Structural Engineer: StructuralEng, Consultant replied 11 months ago
Thank you for the pictures. Do you have a picture of the actual splice condition? And is the deflection of the beam directly under where this splice was made?

Structural Engineer: StructuralEng, Consultant replied 11 months ago
In the very last picture, am I looking at the sheathing on the beam extension at the top of the opening in the picture?

Customer reply replied 11 months ago
they lifted the beam, placed a 3/8" OSB shim between it and the garage frame. And we're adding trusses under the flooring in the bedroom to try & plane out the sag. A framer called out to do repair showed me how even after the shim was in place, the entire garage ceiling was angled towards the drop all along the beam.

Not "we're", but they "were"
Customer reply replied 11 months ago
Basically- would you pay $340k for this house- knowing that there will likely be years of aftermath? And who knows what else is done poorly (not necessarily illegal, but shoddy work all the same)? We foresee having to rip apart floors, ceilings and walls in the future to address the fallout from all this movement. We were at finish work- all the stucco & drywall on & getting ready to carpet & tile... We think wise move is to walk away if they won't do an engineering study on it.

I know all of his pictures makes sense with you taking them and knowing exactly what you're looking at.

PS- moving forward, I am not counting on 'legal' advice and won't be sharing your responses with anyone- this is to help us feel better about walking away from $13k of our hard earned money, because this house may actually end up costing us exponentially more if we allow close of escrow!

J. Flowers and I live in San Antonio Texas. I am selling my
I am selling my house and it is a pier and beam house that had new piers and beams installed in 2011. When the inspection took place the foundation was fine but the report showed the interior floor 4 inches out of level. They said 3 inches was the limit. I had a construction company come out and as it turns out the dining room on the far side of the house is 3 inches out of level too high. Leveling the dining room would make the entire area within an inch or so. The buyers agent sent out a foundation company whos brilliant solution was to jack up the rest of the house to match the dining room. I brought in a construction company that gave me a proposal to remove the flooring and sub floor in the dining room, lower the floor joists to level, replace the sub floor and floor and then trim out. Once this is done the area would be well within the tolerance. Your thoughts? … read more
