Hey what's up guys Alex with Bay Cities Construction here - We're at our job in
beautiful Harbor City (Los Angeles)
and we're working on our soft store retrofit here want to
kind of walk you through what we've gotten done so far
[musical intro]
so let's look up here real quick we've peeled up all of the diaphragm framing
you know we put a new beam in here we're gonna change the camera angle so you can see it
but basically this is all part of the retrofit process the installation of
plywood shear on the outside of the building right it's gonna create lateral
strength this way in this way check this out look at these big beams we put in
here so this is all new this new strap ties everything in this is all the way
to here we're gonna put in two rows of 2 foot long Simpson StronG-Walls so that's
the backing for the simpson strong walls they're gonna be here was a pallet verax
gonna get together move and we're use that plywood over there that's all
structural-1 plywood so we're gonna go over to this other side and I'll show
you what's happening in the other side of the building
in this section here we're doing some more diaphragm framing and basically
it's quite a bit it's about 40 feet about 40 feet of diaphragm framing and
again we're just putting plywood here this is going to help create here
resistance or earthquake let's show you what's happening inside the garage can
you get this out of your way this is our scaffolding so back here I wanted to
show you all buildings are soft two ways they're soft this way we're gonna put a
moment frame over there and it's softened this way in order to deal with
this lateral resistance we're putting in a piece of sheer wall so basically this
is about five feet it's a little bit bigger than the specs it's a spec down
to five feet we they're about six feet cuz we got a better connection here so
we got a big four by eight this is gonna be all shear wall tied in up there and
then bolt it down with a big 24 inch deep bolt
so you can see it's it's pretty significant hold on one second don't go
every retrofit requires a hardware and we have no lack of it here this is a
all-thread rod bad boy goes there this is actually gonna get embedded concrete
it's nice sturdy and it creates tension the Simpson hood goes like that
this goes on here on your wall just anchors down to the ground now you're
ready for rock and roll 8:35 this is absolutely required in software
retrofitting
hey let's go to this side the building follow me okay now we're in this head
ability that's a credit didn't it it's kind of a big building
so this part we're doing the same thing as we're doing on the opposite part
we're peeling the stack and exposing it so we can put diaphragm training so this
whole area here is going to be covered with plywood and we're gonna put a set
of beams like we did on the other side right up here we're gonna put it in yet
this is what it looks like now if you have a building it's similar this you're
gonna have is a two by twelves 60-month Center the entire length of the building
and yet basically at the end of the buildings to create shear resistance
this way the moment frame is going to cover us this way but we need shear
resistance this way so these beams right here basically going to tie this to
business to the new Simpson strong walk forward but here that's going to go into
the and when we come back and we cut the
concrete it's gonna be a lot of fun this whole area here is going to be cut we're
gonna connect the the foundation of that post with this post with a new wall
right here together it's not gonna be soft anymore it's gonna be retrofitted
so that's how we do a retrofit this building is gonna have a moment frame so
we're gonna show you where that's gonna go but we haven't peeled back the stucco
so there's nothing to see yet we're extremely excited to use the Simpson
special moment frame and yes it is special we're going to put out since the
special motor frame on the other side of the building that's gonna give us our
lateral resistance this way so the strong walls that are going over there
gives us our resistance this way I'm gonna make the building stick that way
so really except to show you what that's going to look like it's gonna be cool
we'll make sure we shoot some footage when we cut the concrete and jackhammer
the the slabs down that's my favorite part I love jackhammer
we got a brand new Bosch saw and we are gonna cut this bad boy down we're gonna
cut a big old trench all to the wall and for the moment friend we
get to cut tool it's gonna get l-shaped cut
so stay tuned that's our update for our Lomita Harbor City project and stay
tuned make sure you subscribe and hey if you have any questions about your
building getting it retrofitted get my off this is a call my name is Alex at
Bay city's construction I'll see you on the field remember you don't need a
contractor you need a team of pros
