The Trees and the Forest of New Towers - The New York Times
By Stephen Wallis
Nov. 20, 2019

Mass timber refers to prefabricated structural wood components that can be used to construct buildings — even large-scale buildings — faster, with less waste and eventually with less money........Mass timber refers to a variety of different types of engineered wood components, the most common being cross-laminated timber (known as CLT) and nail-laminated timber (or NLT), in which multiple layers of wood planks, stacked at 90 degrees, are glued or nailed together under pressure to form structural panels. So-called glulams, which are made in a similar fashion and have been around for more than a century, are typically used for long elements like beams and columns.........building with mass timber can ameliorate climate change because it produces less in greenhouse gas emissions than construction with concrete and steel. And wood has the benefit of storing the carbon dioxide trees absorb during their growth, keeping it out of the atmosphere indefinitely.....While cutting down trees to make buildings may not sound environmentally sensitive, mass timber supporters argue that wood could be harvested from sustainably managed forests...At the end of last year, the International Building Code was changed to allow wood buildings of up to 270 feet tall, or the equivalent of about 18 stories, from 85 feet....People want to live and work in these kinds of buildings — they have a sense of connection to the material,”......what we’ve seen from fabricators and builders is that there’s a 35 percent drop in construction time for mass-timber buildings, which means the carrying costs are less.”....

Log Cabins? No, These Wooden Buildings Are High-Rises
Jan. 1, 2019 | The New York Times | By C. J. Hughes.

"But proponents scored a huge win last month when the International Code Council, an influential advisory group in Washington, concluded that some wooden buildings could climb as high as 18 stories, more than twice the current permissible height, without compromising safety."....."In addition to their green benefits, he said, wood buildings perform well in earthquakes because of their lighter weight and flexibility.".....Proponents of wood must still overcome a longstanding bias. In the 1800s, fires were a scourge, prompting restrictions on wood. But steel is not infallible and can buckle in extreme heat, ....“But we’ve gotten comfortable using steel and concrete products, so the question’s been, ‘Why would we change?’” ....Still, wood is not what it used to be. The decline in old-growth forests means developers can no longer count on huge single trunks to support floors. Instead, they rely on mass timber, an engineered product made of layers of spruce or fir pressed together in a way that is similar to plywood but with a more elegant look......Wood remains expensive, but the assembly-line aspect of mass-timber production, in which factories make large panels, then assemble them on-site, saves time and labor costs......

How to build a better future: high-tech Jenga at the Soane Museum
December 21, 2018 | Financial Times | Simon Ings.

Suspended from four wires, this digitally controlled cable robot is building something out of hand-size wooden blocks. It’s a slow beast. Hours must pass before its construction becomes recognisable: a dome, of the sort that John Soane produced for the Bank of England and Dulwich Picture Gallery.

Polibot does not look like a game changer. But according to Arthur Mamou-Mani, whose architectural practice built it, Polibot’s children are going to change the world.......in the early 2000s, computer-generated design was a fairly dry topic. Patrik Schumacher, principal of Zaha Hadid Architects, dubbed it “parametricism”, reflecting the way programmes evolve forms according to a set of parameters........Through experiments in robotics, Mamou-Mani’s practice is out to develop new ways of building that will make architecture, engineering and construction merge into single field. The point is not what Polibot is, but what it could become. It’s not just a pick-and-place machine. It’s the early prototype of a universal builder.....There have been many experiments in the large-scale 3D printing of buildings. But the kinds of industrial robot arms that are usually employed for this work are far too cumbersome and delicate to wheel on to a building site....Gigantic robot arms will never spew out skyscrapers at a single sweep, Mamou-Mani says, for the simple reason that it would make construction less, not more efficient....construction is mostly about bringing big chunks of stuff together,” he says. “Currently, concrete is still the material of choice for the construction industry, but we’re slowly switching to timber, and this will be a massive revolution, because once you start working with timber, you’re no longer casting anything on site. You’re thinking entirely in terms of prefabrication and assembly.”Mamou-Mani dreams of building simple towers from elements (“prefabricated properly, by robotic arms, like cars”) assembled on site by gigantic Polibots....Mamou-Mani explains his vision of buildings that can expand and contract, depending on the economy....Why do we think that permanence is necessary?” Elsewhere in the show, the wall text proclaims that “the best cities are the ones that don’t leave ruins”....All great advances in industrial culture are prefigured by model-making.

Finding New Life (and Profit) in Doomed Trees - NYTimes.com
Aug. 7, 2010 | NYT | By LAWRENCE W. CHEEK. Seth Meyer and
John Wells harvest local urban trees doomed by development, disease or
storm damage, and turn them into custom furniture, each piece a distinct
botanical narrative. Their business, started 4 yrs. ago, bears all the
markers that would seem to point toward collapse and extinction in a
recessionary economy: founded on idealism and emotion & riddled with
huge and unavoidable inefficiencies. And it tenders a high-end product
that asks buyers to take risks and have faith. Yet the company, Meyer
Wells, has thrived. It’s been profitable from the start with rev.
growing annually; $850 K last yr. and tracking to top $1 M this yr.
There are now 9 employees, and the furniture commissions have blown well
beyond suburban kitchens to high-visibility clients (e.g. Starbucks,
the Univ. of Washington). ...Green bus. fail for the same reasons others
do: racing too far ahead of the mkt. or failing to control costs.

Wealthy Investors Discover Timberland - WSJ.com
MAY 1, 2010 |WSJ| By JEFF OPDYKE.

*********************************************************************
https://www.landthink.com/timberland-is-for-small-investors-as-well-as-large/
*********************************************************************
The timber business as an asset class makes sense only for ultrawealthy, ultralong-term
investors.Timber isn't lumber, the commodity that trades as relatively
short-term futures contracts. Timberland is the farm from which lumber
ultimately comes, and is a long-term holding.Think decades.Timberland
investing works best at scale = a difficult investment for people of
lesser means.Small plots lack the muscle to generate meaningful income,
since only a fraction of the trees are culled at any one time.The avg.
timber tract is = 400 acres in the Southeast, the US 's wood basket.At
roughly $2k/acre, that's an $800k ante just to play.

Wealthy individual investors typically put their money in timber
investment-management organizations, or TIMOs, which cater largely to
institutions, but which often accept individuals investing a minimum of
between $1 million to $5 million. Some TIMOs do allow individuals to
pool money into a single account to meet the minimum.
