Have another small project. This one is a small construction office at a manufacturing plant, it will be permanent. The office will be basically a mini home (16"x34"). The floor system is typically 2"x10" supported by (2) 3 ply 2"x8" that run lengthwise with the floor joists cantilevering 24" on...
Have a question about a hot tub on a balcony. Have a client who wants a two car garage with a two bedroom apt above. The garage ceiling is to be 12'. They want a balcony off the main bedroom and then place their 6 person hot tub on that balcony (12'x12'). What things should the client be warned...
From my understanding unbalanced snow loads are to be considered when designing trusses for single family residential homes (ASCE7-10 Section 7.6). I work with a home manufacturer who designs their trusses as monoslope trusses. On site, when the modules are put together the monoslope trusses...
Not sure if this is the proper forum for this question but here goes
I believe in the US a window that meets all these criteria:
-The window measures more than nine square feet
-It has a bottom edge that’s under 18″ from the floor
-It has a top edge that’s more than three feet above the...
I have a question about the 2015 IRC on joist spans.
Table R502.3.1(2) (residential living areas LL-40psf, DL-10psf, L/delta = 360) states that for a 2"x10" @ 16" SPF #2 the max span is 15'-5". But I have an engineered calc sheet (Woodworks Sizer 11 USA) that shows the max span is 15'. The calc...
Hello all,
I've noticed more and more that designers are specing reinforcement for concrete foundation walls. In this case I am talking about standard construction, nothing fancy. I am talking about single story or two story homes that are typically rectangular in shape, about 28'x 48'. No...
Hello All,
Been working on a few projects (two story manufactured housing in Canada). Due to the way the homes are put together onsite the main floor modules have 2"x6" ceiling joists. These joists only support the gypsum ceiling. The joists are fastened to a sill beam and rest on the top of...
Have a situation where a deck floor (with roof) is supported by a 3 ply 2"x10" beam (floor and roof loads). The floor joists bear on the top of the beam and the bottom of the beam isn't laterally supported. The beam doesn't pass without lateral support on the bottom edge (tension). If there is...
Hello all
I have a question about minihomes, specifically the way the floor joists cantilever over the support beams on either side of the home. We have a group of homes going to northern Labrador where there is a heavy snow load. These are standard minihome designs that are shipped throughout...
I see someone asked a question about Woodsizer a couple threads ago. An engineer we work with also uses Woodsizer and has calced a few beams for us. I noticed a note on the calc sheets about the load on a tributary width is increased 125%. Here is the actual wording "Beam is a continuous support...
This is more of a curiosity thing than anything else.
When you compare the 2015 IRC and the Canadian NBC 2015 span tables a 2"x10" floor joist @ 16" OC spans 15'-5" (IRC) but only 13'-8" (4.17m) in the Canadian tables.
While I know the calculation process is different in Canada as compared to...
I have a question about temporary construction loads in Canada.
I am working on a manufactured house project. The house is basically in two rectangular boxes that will be craned onto the foundation on site. The house is under 48' long and I'm told the home will be craned by two straps (each...
I have a client (single family residential) who is asking for a foundation that is a standard ICF 8' wall supporting about 1/3 of the house footprint (they want utilities/mechanicals and storage here). the ret of the house they want slab on grade (they want the floor finish to be polished...
This is a Canadian question (NBC2015). I have seen floor dead loads of 10psf used for years. Now I've been told that we are to use 15psf for floor dead loads. I can't find anything in the code, except for in the user guide for wood foundations where 11psf floor dead load is used, of course I may...
Good Day Everyone,
I have a client who sets minihomes here in eastern Canada. They have been using an ABS pier pad to support the CMU piers. They have a chart of the maximum load capacity of the pads depending on the unconfined soil compressive strength. This chart is an American chart and...
Hello all,
I have a software and code question. I am working with a company that provides manufactured housing to the US market. They use a software package that references the IBC 2018, NDS 2018 and the ASCE 7-16.
Since we build single family homes our third party inspector has requested that...
Not sure which forum this should be in (maybe someone here could direct me if there is a better forum) but here goes anyway.
In the USA any window within 18" of the floor is required to be tempered.
Is there a similar requirement in Canada?
I've looked at the Canadian National Building Code...
I have a friend who wants to add a frost wall under an existing addition to an 120 year old home. The couple had purchased the home within the past year. The main home was built on a mortared stone foundation forming a crawl space under the home. At some point a small addition was added...
I had a discussion with a manufactured housing company on how they deal with their built-up beam calcs. Their typical home has a rectangular footprint and has a built up beam down the center supporting floor joists...pretty standard. This beam is continuous over several spans, again, pretty...
Hello All,
I am working on a project that is a little unusual. It is a small commercial/residential building (30'x70') that will go onto an existing foundation (10" thick concrete walls, 8' high). The foundation was poured a few years ago by another contractor then the project was abandoned. I...
