We’re going to be installing a pair of Simpson “Strong Wall” shear wall systems for the first time and was wondering if anyone could offer any tips or caution me on things to look out for. I’ll buy the anchor bolt template to set the bolts, but I was wondering if it’s easier to set these shear walls first, then raise the other walls around it or leave an appropriate space in the framing layout and install the shear walls later.
If I leave a space, what would an acceptable clearance be, 1/8″, 1/4″, none?. I was guessing I’d had to leave some gap to allow for plumbing the wall.
The shear walls will be the Simpson standard SW24X8 for slab-on-grade construction. They will be placed on the ends of a 16′ wall that’s filled with windows and a slider.
Thanks for the help!

Having been around a few contractors who have had problems installing these units I will advise that you get the full installation guide, not just the short version on the label, for the unit you want to use and follow the directions to the letter. No shortcuts, judgement calls or substitution are allowed. The carpenters who have had problems had them because they guessed at or fudged a detail or two. Seemingly minor details can comprise the entire structure. Inspectors, as they should, look at these installations very closely.
That said don't be afraid of these units. Given reasonable care they are not that difficult to install and have pass inspection if you follow the rules. Two points:
If Simpson makes the wall. Use only Simpson's hardware. This is not a place to save nickels on cheaper parts.
Also watch the other trades. I saw one that had to be completely replaced because a plumber installed a hose bib and butchered the framing of the structure. Dire threats or armed guards, in some cases, may be called for.
Edit for grammar.
