Home Improvement Chains Accused of False Advertising Over Lumber Dimensions (consumerist.com)

per unit analyzer writes: According to Consumerist, an attorney has filed a class-action lawsuit charging Home Depot (PDF) and Menards (PDF) with deceptive advertising practices by selling "lumber products that were falsely advertised and labeled as having product dimensions that were not the actual dimensions of the products sold." Now granted, this may be news to the novice DIYer, but overall most folks who are purchasing lumber at home improvement stores know that the so-called trade sizes don't match the actual dimensions of the lumber. Do retailers need to educate naive consumers about every aspect of the items they sell? (Especially industry quirks such as this...) Furthermore, as the article notes, it's hard to see how the plaintiffs have been damaged when these building materials are compatible with the construction of the purchaser's existing buildings. i.e., An "actual" 2x4 would not fit in a wall previously built with standard 2x4s -- selling the something as advertised would actually cause the purchaser more trouble in many cases.

      However, the above poster's claim of a 50 year useful life on new construction actually makes me wonder if "modern" houses (those built since the 1980s or later) actually have a shorter expected lifespan due to the mass production techniques and engineered components which actually might not last, like truss joists, LVLs and some of the chipboard materials.

      OTOH, in the last 15 years building codes have gotten a lot stricter, and require a lot more steel to be used in tying elements of the frame together, foundations are more thoroughly engineered, etc.

      I suspect that houses built in the last decade or so will last a long time. Houses built in the 70s, 80s and 90s, maybe not so much.

      On the gripping hand, it looks like there may be a wave of new construction techniques coming which will dramatically lower building costs, maybe by as much as 80%. That could well mean that the durability of current houses is irrelevant, because it could get to where it's cheaper to tear down and rebuild than to remodel. I'm in the middle of a major remodel project right now, and the cost will easily exceed 30% of new-build cost.

      The main new construction technology I'm thinking of is 3D-printed concrete, whether 3D-printed in place or (perhaps more likely) 3D-printed forms, with most of the panels pre-cast and shipped in. The thing about the application of high-precision 3D printing to concrete forming is that it allows very precise control of shapes which in turn enables great strength without thickness (and hence weight). Your home's roof could be supported with flying buttresses, light but incredibly strong... and mostly dropped from construction because creating such complex shapes is too labor-intensive. Being able to model complex, precisely-engineered structures in CAD systems and then produce them cheaply and with fine tolerances may dramatically change construction.

      And note that the effects of such an approach go far beyond just the basic structure. A lot of the cost of a modern house is in the stuff built after the frame is up: plumbing, ductwork, electrical and finish work. With precise control of concrete casting it should ultimately be possible to include channels for all of that stuff right in the walls. Air ducts -- and maybe even plumbing -- will no longer require any sort of pipes, just channels in the concrete. A great deal of interior finish work could be eliminated as well. Polished concrete walls could potentially require no additional wall finish at all. They could even be "painted" simply by mixing pigment into the concrete before pouring. Even things like toilets and bathtubs could be pre-cast as part of the structure (though I suspect probably wouldn't be, for a variety of reasons I won't elaborate here).

      We may get to where a house can be fully assembled in a day, with a small and mostly automated crew. A design customized to the shape of the land could eliminate most excavation. Then pre-cast and mostly-finished pieces would be delivered, placed by automated cranes and joined with an appropriate sealant. Plumbing and air circulation would all be pre-cast in the walls. The HVAC system can be dropped into a slot cast for it... and dropped in with a crane before the roof or other overhead floors are installed, making installation easier. The same is true of all other appliances. Interior walls and floors could arrive mostly pre-finished. Carpet or other non-concrete flooring, plus light fixtures, cabinets, etc. could all be lowered in before the roof goes on. All that would be left is to install fixtures, cabinets, toilets, etc., pull electrical wiring through the pre-cast conduits, hook it all up and test. And installation of fixtures, etc., would be facilitated by having prepared spots for all of them with threaded holes cast for the bolts to attach them.

      Once the advance of storage technology slowed down enough that there wasn't a factor of two gain every year or so, we started to see counts that weren't powers of two. Designers would squeeze a little more out of the tech by cramming in a few extra sectors, tracks, or both. It really all went out the window once we got variable density recording: magnetic media that store more bits on the outer tracks and fewer bits on the inner ones, keeping the bit density per unit of volume fairly constant.

Later versions changed the bit clock in the controller instead, which was faster and more reliable but less fun to listen to.)

For example, a phone with 3GB RAM (actually 3 GiB) probably has three RAM chips inside, each of which holds 1GB. It might instead have one 2GB chip and one 1GB chip.) But SSDs use flash memory and it wears out over time; each memory cell can only have data written to it a limited number of times. SSDs have to do things to spread out the writes over the entire drive, and also usually have some degree of overprovisioning to allow for bits to fail. (In other words, some of the memory is deliberately set aside when you buy the drive so it can be used to replace areas of the SSD that fail, just like the modern hard drive does.) The flash memory chips inside the SSD are usually in sizes based on powers of two, but the amount of space that the user sees is somewhat smaller.

      The timber industry (or home repair? Who??) decades ago redefined the size.

      Nope.

      The 2x4s in your house are rough-cut. A jointer and plane were not used to shape the wood into a flat and straight board.

      It was standard practice when your house was built to not do so, because that jointer and plane removed a variable amount of wood depending on how twisted and cupped the raw 2x4 was. So a 2x4 that started out pretty straight could end up 1.9x3.8. And one that was much more warped could end up 1.25x3.5.

      Since trees were cheap and plentiful, and wood was commonly used for fuel, they just didn't use the warped wood for construction.

      As wood stopped being commonly used for fuel and trees became more valuable, throwing away the warped boards became a bad idea. Instead, the industry decided to start straightening the warped/cupped boards using the above-mentioned jointers and planes. But they still needed consistent sizing for construction, so they cut 1/4 inch off each face to deal with cupping and warping in most boards. That yielded a 1.5"x3.5" piece of wood.

      "One-and-a-half by three-and-a-half" is pretty awkward to say compared to "two by four", so tradespeople still called the finished wood "two by four" because that was close enough - it's not like those 2x4s in your house are all exactly 2" by 4" - they weren't that accurate cutting wood, and the wood will have shrunk in the intervening decades.

      Meanwhile, construction techniques advanced such that the 1.5x3.5 wood could be used in places where they used to use 2x4 (primarily from abandoning balloon framing).

And the sizes were set many, many years ago, when manufacturing costs were cheap, and stuff was made to last several lifetimes. In short, the wall of the pipe was a hell of a lot thicker then. Even today, you get multiple schedules of pipe, from 40 (which today is sorta standard for quality work) to 80 or even higher - the higher the number, the thicker the wall, the more pressure it can hold. But the outside diameter has to be the same on all sizes. (Copper pipe, of course, has a thinner wall than steel or plastic, and thus has "types" - M, L or K - instead of "schedules", but the principle is the same.

That means it had too much moisture content to be used right away, it almost certainly twisted significantly along its length, and was pretty far from rectangular in its cross section. But that cross section was at least two inches by four inches.

    So lumber wasn't sold ready to use. What you did was you stacked it in your barn for a few months to dry out, then if you needed an accurate shape you'd run the board through a jointer-planer to produce smooth, precise, parallel surfaces. Both these operations reduce the dimensions of the finished lumber.

    By the early 20th century lumber mills started doing all this work for you so you could buy a 2x4 board and use it the same day. Far from cheating the customer as you claim, they're actually adding value by curing it and milling it down to a standard shape. Since 1924 the standard has been that 2 inches rough-hewn is always planed down to 1.5 inches; 4 to 3.5; 8 to 7.25, 10 to 9.25 and 12 to 11.25. But if you went to the lumber mill with a tape measure, you'd see that the 1.5 x 3.5 finished boards indeed start their life as 2 x 4 inch rough boards.

    If you think about it, a lumber mill that cheated its customers on dimension would go out of business fast. You'd lay out your project, figure out how many boards you'd need, and not only would you come up short, nothing would fit as expected. The whole point of milling the softwood lumber to a standardized dimension is that you could plan out your material requirements exactly and then buy exactly what you need, when you need it.

Every time I come across this I want to scream.

    Because back in the 1910s it was still common practice to buy and use rough lumber. If a 2x4 were reasonably straight you wouldn't bother milling it down to size, you'd just cut it to length. But if you were to look at the subfloor (that was before plywood) you'd find that the width and thickness of the boards is about a half inch less than nominal.

    There isn't strictly speaking any reason you have to used finished lumber for everything, but because of economies of scale there is no longer any economic advantage to using rough lumber. The carpenter who built your garage probably picked over the 2x4s at the lumber yard. Milling all the boards down from their nominal dimensions makes that job easier, and reduces the reject rate so everyone wins.

    Lumber dimensions

    Lumber's nominal dimensions are larger than the actual standard dimensions of finished lumber. Historically, the nominal dimensions were the size of the green (not dried), rough (unfinished) boards that eventually became smaller finished lumber through drying and planing (to smooth the wood). Today, the standards specify the final finished dimensions and the mill cuts the logs to whatever size it needs to achieve those final dimensions. Typically, that rough cut is smaller than the nominal dimensions because modern technology makes it possible and it uses the logs more efficiently. For example, a "2×4" board historically started out as a green, rough board actually 2 by 4 inches (51 mm × 102 mm). After drying and planing, it would be smaller, by a nonstandard amount. Today, a "2×4" board starts out as something smaller than 2 inches by 4 inches and not specified by standards, and after drying and planing is reliably 1 12 by 3 12 inches (38 mm × 89 mm).

    I had a few small building projects and assumed - based on the name - that a 2x4 was indeed 2"x4". My little project came up a bit short when the supporting boards weren't as expected, and that's when I learned the difference between rough and finished wood. That said, I know the difference *NOW*, but it is still somewhat along the lines of mebibytes VS megabytes etc (or X-inch "class" TV's) where it could be confusing to a non-professional or first-timer.

    So there is the question of whether the difference is still necessary, but to be honest I *also* wouldn't be surprised to see that some stores might cut lumber down a few fractions of an inch more these days in order to get more boards out of a log. I haven't seen anything that says an exact number that it a board should be under 2x4" so what's to keep them from having shaved a bit more here and there to cut costs?

  64. Reason for Standard Units by Roger+W+Moore · · Score: 1

    How the fuck is this "cheating" anyone?

    Units have legal definitions to prevent vendors from redefining their own units as they please. This was what happened back in medieval times and is why we have standard units now. It might be easy to remember that the cross-sections - but not lengths (how inconsistent is that!) - use non-standard definitions in construction but suppose petrol stations started doing that for litres? or electrical utilities redefined the kWh? or estate agents redefined the square metre etc. We would rapidly get back to where we were in medieval times with nobody really knowing how much of anything they were buying because everyone has their own definition of each unit.

    Just because only the construction industry do this and it is easy to remember is not a valid excuse. What they are doing is illegal under the trading standards of many countries and it's about time someone called them on it.

  65. Define "accepted standard" by Roger+W+Moore · · Score: 1

    Such a reaction just shows ignorance of an accepted standard

    The problem with this is how do you define an accepted standard? If you found that a petrol station only gave you 0.9 litres of petrol everytime you bought what the pump said was a litre you would feel cheated even if the station told you that this was their accepted standard, indeed even if every petrol station started doing this suddenly you would still feel cheated because it is not the standard unit that you accept.

    This is why, since medieval times, we have had laws that define the accepted standards for units. You are not free to redefine the length of a metre as you see fit you are required to follow the standard set out in the law. The reasons for these laws are extremely sensible and there is absolutely no valid reason for the construction industry not to follow them.
