How to Prepare a Foundation with Helical Piers for a FLOOD ZONE 

Absolutely beautiful.

I am also interested in how they get the water main and sanitary lines up to the building.

They’re installing breakaway skirting around perimeter which should trap warmer air than outside. Between the skirting, wrap the sewer and water main in 2” closed cell foam or Armaflex and that should be sufficient given that climate. In colder climates you’d wrap lines in heating cables with automated thermister. I highly doubt that is necessary in this coastal setting that likely never sees sub-zero temps.

I asked the same almost a week ago, no response. My guess is they do not respond to comments on channel. In many cases frp is not used due to cost, sometimes supply and many times its lack of knowledge/familiarity. For cost, yes it’s typically 15-20% higher than coated steel. When factoring in labor to inspect & re-touch all coated steel damaged during installation, as required by structural engineers, the material cost is roughly equal; often cheaper on very large sites such as subject. In terms of supply, it’s not just ordering the lengths on site, it’s spec’ing the bends which must be done at factory during fabrication. Where I am in high Rockies, we have supplier down in Denver 90 minutes away with typical lead times of under 2 weeks. Working off structural drawings, all materials can be ordered within required lead times w/o issue. Can same be done to this job site? While frp rebar has been around for decades, there remains a lack of knowledge. Many builders and engineers prefer to stick with what’s familiar. Even within frp space, they lack application knowledge between gfrp, cfrp and bfrp. When, where and how to use each. In this case gfrp or bfrp would have been more suitable than the coated steel at comparable cost delivering superior long term service.

My parents want to invest a seaside property in China and the property needs to be rebuilt due to severe sea side corrosion ( it is literally 1m above sea level; the first floor is partially submerged once a year due to high tide between August and September). So I did extensive research on the topic and conclude that 316/317 stainless steel is better option than FRP for house; however, this drastic material change of material used in the building requires special permit to be built because it may break code: SS has superior elongation, fatigue, creep performance but the tensile strength is about 200MPa (CW carbon steel 300MPa-450MPa). And here comes the major obstacle: the city is not far away from a couple very active seismic zones; consequently the lower tensile strength may break the city's building code but in fact due to its superior fatigue/elongation, it can take way stronger earthquake and it is potentially repairable compared to carbon steel) 2205 could be a very good candidate if I can't get city to agree on using 316/317 but it is nearly 4-5 times more expensive than carbon steel where 316/317 is about double: 2205 can easily outlast anything in the market since that it has combined the strength and corrosion performance of carbon steel and 316. The problem with 2205 is more to do with welding: in China, I may get a shipyard/chemical reactor producer to do the weld. The rationale for choosing steel or stainless steel rather than FRP for building is that: underwater structures around the world right now are built using 2205 SS for its ability to form oxygen-free oxidation layer; and the bridges are built 316LN/316LVM/317SS in the air column section since there are plenty air to form the oxidation layer. 2205 is better for the splash zone but 316SS is generally sufficient for residential building. Besides, there are always fire and creep concern on FRP; and don't forget the FRP are heterogeneous material so a proper load design and onsite-installation could be an issue. China has banned the use of epoxy coated rebar in civil engineering due to premature crevice/pitting failure from imperfect coating since early 2000.

On top of this, I should say I see most buildings in my city back in China are built with concrete with "waterproofing" additives especially for the ones right beside the sea right now.

Ffs dude, get a life🤦‍♂️

Well Jesus endorsed someone putting oil worth a years wages on his feet, so the likelihood is that if living in the house was in his father's will, then he would have done it. However, I don't see how any of that is relevant to house building.

I showed this video to Jesus; he said he doesn't like the climate there, but if it were built in a warmer area of the country, he might move the family there if his wife liked the house and there was enough room for his 2 kids and his mother-in-law.

Lol. Sea levels rise as climate changes. The earth is not a static environment.

@@Freerunx3 how much have the seas risen?

@@jaker1160 3.3mm per year since at least 1993 which is 3.6in in les than three decades

@@jaker1160 Does everything need to be spoon fed to you? Ffs just read a scientific journal, you might gain whole new perspective on life and the world in which we live.
