Bunt, the hazard of this is on pour, the forms are likely to settle. With the 2x4 struts, the only side that could settle is outside so the wall could lean or bow if the braces allow it, especially with taller walls. It's hard to fasten the diagonal foot of braces to keep from pulling out with great force. |

On that particular pour, we used a tongue and groove block. We glued every joint vertically and horizontally. Based on past pours with this block, there was little or no compression in an 8' pour. I can see the compression being an issue though with most interlocking blocks though. I have experienced up to 1/4" comp in a 10' pour with amvic. The only time we seem to have compression with the t&g block is if the footing was out of level and there was lots of shimming done. The blocks themselves have full contact with each other which minimizes compression. That's one of the very few benefits I've found with a t&g block.

True. I suggest just an OSB patch at each hole to hold the ABs.
I wonder where the OP went? |

I use 8' strongbacks if a floor system (between 8'1 and 10') is being installed, Granted every block has some settlement. The blocks I prefer to use have minimal settlement if any (and we've all discussed the various reason for settlement in another thread and ways to avoid it) and if a floor settles an 1/8" over 50-60' I'm okay with that, majority of framers don't get it that close. I find this method faster since it doesn't involve the having to layout perfectly after the bolts are in and lift a heavy LVL up ladders (since most guys use 10' strongbacks they can't be there when doing the floor) only to find your bolt hole off a 1/4", back down the ladder, redrill, back up again, you get the picture.

I leave the ledger to the framers, but just set a laser, hold the ledger, and mark the bolts. (Tell them don't bang on the board! Concrete's not set yet)
Speaking of strongbacks, what kind of bracing do you use C? I really like Giraffe, but the only distributor is a competitor who has not been friendly at all. {cough} Looked at Superior which is nice and light, but they look very cheaply-made, plus I must have tall-wall extensibility. |

Q; I use Nudura braces, carry 8, 10 and 12's, for tall wall (cough) that's not discussion on a public forum (cough, cough)
Got a link for the Giraffe brace?

Reason I asked top or bottom chord bearing. Top chord wood open web trusses usually have a double 2by4 top plate. Hang this truss on a single fir ledger with ICFVL, but then scab a 2by4or 2by6 on the ledger with appropriate nail/screw pattern to assist the truss to bear on 3 inches of "ledger"
Bottom chord bearing wood trusses usually sit in hangers or on walls, and why would you need 3.5 inches of ledger would be my next question.

Bunt, you seem to have a little more experience than you have lead us to believe. Where exactly are you in this industry?

Dave, I am sure I don't have near the experience with icf's as most pro's that frequent this site. I only do 3-5 homes a year. I have a set of 60 paneljack 10' reechcraft bracing as well as a set of 40 liteform braces w/dietrich metal studs, so there are some DIY I get involved with as well. The homes are typically all ICF. I typically draw the plans as well w/chief arch, so I try to incorporate everything I can into the plan that will make things easier, whether it be dimensions, wall transitions, floor support, new products, etc.

Word. It's sometimes preferable to rent so you can determine what works for you, but there are some deals to buy too. |

Quantum, Buntly, Chris...
You guys bring in a good subject lolll The Only part I didn't tackle yet or actually mark off is the bracing. What am I suppose to do for bracing ? loll
I don't wanna rent teh braces ( comes to 16000$ ) for the entire project. but don't wannna be caught with them after... Buy then sale ?
What about Price/quality ratio in this case....
Francis

Hoooey!,....there's probably an infinite number of ways ya could go. Could get some hat brackets and turnbuckles and use lumber. Could buy some liteform braces and dietrich metal studs and then use 2x w/turbuckles for kickers. I bought turnbuckles a few years ago,......think I paid $8/ea. The liteform braces were $18/ea. When all was said and done, I think I had about $30 into each brace. You could also try and work a deal out with your block supplier. Ya could also custom make your own. I custom made some for a pour I did a few years ago (see attached). 16' pour and brace was 16' tall with two different scaffolding locations. Had the braces made at the truss company. Think I had about 600.00 into 45 sets of 16' tall bracing. I will probably never need bracing that tall again, so it was smarter for me to custom make my own for a one shot deal. If I can figure my scanner out,...I'll post some pictures of the liteform setup.
Francis,.......if you want me to email you a plan of how to make your own set of bracing out of angle iron, let me know, I'd post it here, but file size is too large.
http://www.ellisforms.com/managed_files/2393/08_prices.pdf see page 15 for turnbuckles.
Bunt
okay, the fricking file size is too large of the custom brace I made (didn't think 350k was too big)
anybody know how to shrink file size below 100k?

If your rental is 16k, what is the cost to buy? If you can buy, use, then sell and the final cost to you is under 16k, you win.
Expect to get 50-60% return on them when you sell them if they are kept in good working order and not plastered in excessive concrete.
I sold mine before moving to the US (Cost to ship was expensive, bought new when I got here) I actually got dollar for dollar since the cost of bracing skyrocketed back then and I kept them clean
It's amazing, you train the crew when the pour is done to remove the excessive concrete and hose them down, they stay in pretty good shape. |
