Anyone use beam and block for their first floor? If so I'm looking for help with drain pipes.

[Boyblue]

Did you have to run drain pipes in any of your main living spaces?  How did you enclose the pipes?  How much ceiling height was utilized? Were you still able to get the ceiling height you desired and did it involve adding extra courses?

You need to allow a ~150mm service void (gap from underside of block beam floor to the suspended ceiling system)

 

On that note, you'll need to use a metal suspended ceiling system - metal brackets, hangers, channels, where plaster board is then screwed in to.) are such systems readily available in Bahamas?

 

I really do think you're looking at the completely wrong solution for your build.

We have B+B first floor. Layout has all bathrooms along one side of the house.

 

Pipes from shower trays run in the insulation and screed for the UFH. No plynths needed. Low but not ultra low profile traps needed. (Some ultra low traps don't meet building regs).

 

One down pipe/stack is in a downstairs cupboard, another in the corner of a utility room.

Who what in the where now??!!??

 

@Boyblue, you pay for the hotel and beer and I’ll come out and build it lol.

 

I worked on a cruise liner out in the Caribbean, and sailed around the islands, was amazing. Repairing the open deck cafe roof, with 2 pairs of sunglasses on to stop from going blind with the sunlight 🌞. Was sad to come home….. 🥥 🏝️ 🍻

Why do you say that? I’ve recently specc’d a large dwelling with GF and FF in hollow core concrete precast decks, with a service void below. 
 

If somebody wants a ‘solid’ masonry deck then let them fill their boots  

 

If posi joists aren’t the local (Bahamas)  flavour then nobody will know anything about them.

70 million Brittons can't be wrong, (not to mention India and several African Countries) The more I research the more I like it.  Sort o like the metric system, it just makes sense.  Our good buddies to the north can be wrong every now and then 🙂 

 

In terms of the extras, I get your point. I'd have to over order everything because a short on an item like that bracket could hold production up for days, possibly weeks.

Good info, didn't think about closets and cupboards

LOL, I spend about 10% of my time in the sun, havenbeen on the beach in 40 years even though I drive by it every day. If you lived here you'd grow weary of it as well.  I always tell folks, having sunshine all the time is a blessing, but so is having our seasons.  O course you're welcome if I ever turn this discovery into something.

Yea shipping assembled stuff like that is a nonstarter especially when it's already pricy in its own market.  Glulam has been around or years and the amazing things I see them do with it is impressive, but you’re never going to see that stuff here in everyday construction.  Shucks, Insulation is available but because it’s so bulky, it’s priced beyond standard construction.
