So I know that house inspectors only look at surface things. In the UK it seems like structural stuff are checked by professionals before a house sale. In Canada what are they called?
In buying older houses, I would want to evaluate how much I will expect to spend on things like well, septic, roof. But I also want evaluation on if this is a money pit with foundation, structural, or water issues that can't be fixed.
Like @Captcha_Code, I've tried calling structural engineering firms that seemed confused or give $5000 just to take a look estimates. What are they called in Canada and if possible can you provide examples of a firm in any Canadian area so I know what to look for in Atlantic Canada? Searching for geotechnical professionals bring up major infrastructure type of firms.

Share your fav environmentally-friendly building tech!
We've all heard about solar PV panels, but that's not the be-all and end-all of technologies which could make buildings more efficient and less harmful to their environments. May I ask what else...
We've all heard about solar PV panels, but that's not the be-all and end-all of technologies which could make buildings more efficient and less harmful to their environments. May I ask what else have folks got up their sleeves?
Dimensions of environmental friendliness
All good technical discussions start with a host of term definitions and context statements, so I'll attempt to start this one off on strong footing! I figure that anything which checks one or more of these checkboxes (reasoning included) works, but please feel free to colour outside of the lines -- this is just a kicking off point. Note that anti-ticking a checkbox is fine; everything has trade-offs, and sometimes paired solutions can negate each others' downsides. Magnitude is always a factor, too, since this field is rarely black and white.
(no need to bring receipts, mind; I'm sure we can keep this light hearted so as to avoid digging into comparative EPD critiques :3)
- Low embodied carbon (the kgCO2e emitted per a cradle-to-grave analysis (EPD, often) of a product),
- Low operational resource consumption (anything which works as well as an inefficient equivalent, but uses less energy/consumables -- LED vs. incandescent bulbs, heat pumps vs. nat gas furnaces, insulation vs. no insulation, etc.),
- Includes water conservation, too!
- Durability over design life (per the Canadian Wood Council (they're ... a little biased), the median service life of buildings is <90 years, so adjust amortization periods accordingly),
- Includes things like wildlife-urban interface-safe materials, as well as clay bricks and whatnot.
- Sustainability (if we can't do it for more than a century, let alone a few decades, it's probably not worth the sunk costs),
- Low environmental toxicity (no point trying to save the environment if it's all a toxic swamp afterwards),
- Supportive of local ecology (built environments tend to be biodiversity deserts -- cobblestone boulevards, brick walk ups, and tin roofs are hostile everything but pigeons and rats. Think native planting, green retaining walls, planted pavers, etc.).
(full disclosure: I'm probably going to borrow several of these at some point, so this is a half-discussion, half-I'm-outsourcing-my-research post 😅 hopefully that's acceptable ...)

What kind of contractor do I call to evaluate another contractor's work?
I'm going to try to make a very long story short, but we had a large structural retaining wall replaced. The driveway sits on top of the retaining wall. It is about 7 feet tall at the highest end...
I'm going to try to make a very long story short, but we had a large structural retaining wall replaced. The driveway sits on top of the retaining wall. It is about 7 feet tall at the highest end and tapers down over about 30 feet.
We selected a contractor who was at the higher end of the price range but not like the highest highest. It's not like we cheaped out. But we are SO not happy with the work. There are sagging "deadman" posts, there are a ton of shims forced into it to make it lean the correct direction, and it is visibly not dug out enough.
We have tried to work with the contractor but he keeps cheaping out and "jerry rigging" it further to fix the defects. At this point, we are thinking small claims court. We want an expert to come out and tell us if it is structurally sound and document the defects.
I thought maybe a general home inspector could just inspect a part of it, but we contacted three and they said they only do whole structure inspections, like the whole house. And even if the retaining wall was included they would not really look much further than making sure it's not rotten. I tried a structural engineer but the two I contacted almost seemed confused at what I was asking. One just told me they don't do things like that and the other one I'm pretty sure just wanted me to go away and said $10k.
What kind of speciality can tell me if this thing is going to collapse or not? I feel like this is important information if we sue the previous contractor. Any help would be appreciated.
