Building taller buildings: in wood, not reinforced concrete

An article in today’s local media reports that British Columbia’s Premier Gordon Campbell is proposing changes to the province’s building code to allow wood-frame construction for buildings taller than 4 floors.

Going higher … using wood

A plan by the province to raise the minimum height for wood-framed apartment buildings to encourage more use of the province’s timber is receiving strong support from builders.

Premier Gordon Campbell told mayors attending a Whistler convention he wants to support the province’s forest industry by allowing the construction of wood-framed condominiums above the current four-storey limit.

Housing Minister Rich Coleman told the Canadian Home Builders’ Association he wants to see wood-framed building up to six storeys high. Coleman said the necessary building code changes could be accomplished through regulatory change and could be in place by September.

B.C. is already pushing the limit under the National Building Code by going as high a four-storeys in wood, said architect Richard Kadulski, but going higher, is doable, he said. [Article here.]

Sean Holman of Public Eye Online asks, “So where did the Campbell administration get the inspiration for this plan?” And answers as follows:

Well, back in February, International Forest Products Ltd. vice president Ric Slaco attended a Campbell administration climate action meeting. And, at the meeting, Mr. Slaco delivered a PowerPoint presentation [*] urging the government to promote British Columbia wood products by making “BC’s Building Code and procurement policies wood-centric” and expanding the province’s wood first policy to private buildings. This, as part of an effort to increase wood product use in construction for both environmentally and economic reasons. Fancy that! [Article here.] [* note: the presentation links to a 30-page PDF, worth clicking through on.]

Hotly debated already are safety issues (fire, seismic issues) and feasibility of building “that high” using wood. But for those willing to brave a bit of German, here’s a link (via Architekturvideo.de) to a company in Berlin (E3 and Kaden + Klingbeil) that’s building the first 7-story building in wood in that city. It’s causing a stir there, too, because people just assume that stone is what endures, concrete is a decent second place, and wood just doesn’t rate — it rots. But if you watch the video, you’ll be convinced that it’s entirely possible. I have to admit that their construction techniques are spectacular, almost over-engineered, and I have no idea whether BC’s builders will be held to quite that sort of standard. If the buildings are to last, however, maybe BC builders and architects should check out the Kaden +Klingbeil video and pick up a few tricks.

Note that current building codes in Berlin allow for wood construction up to 5 stories, so this project (E3) is breaking that barrier.  Note also that it has to meet very stringent fire code regulations: if you watch the video, you’ll see that basically all the wood (except for some ceiling panels) is covered up with thick slabs of fire-blocking material, which is why the building doesn’t look like it’s made of wood.  The architect also talks about how energy efficient the building is, as well as the building method.  There’s a lot of carbon off-setting in this construction material (which is what the BC PDF emphasizes, too).  In addition, the architect mentions that this building took only one third of the time to build as opposed to concrete construction.  In other words, you can get people into housing faster using wood.

• Do tourists miss ‘Toronto the Good’? - Posted Toronto - Annotated

  While some people say that “gritty” = “edgy” (and therefore “cool”), there’s an undeniable line that gets crossed at some point, and then gritty isn’t edgy anymore, it’s just shabby & run-down & dirty. It seems that too many North American cities are on their way to that, primarily because of problems brought on by aging infrastructure as well as social infrastructural neglect. I’m reminded of my oldest sister’s visit to Victoria a couple of years ago. She lives in the heart of Tokyo, and her observations of Victoria were that it’s dirty — which would no doubt come as a shock to Victorians, because we think our little city is so …well, green and tidy. But then she didn’t mean its air (compared to Tokyo), which is clean to breathe.  She meant the litter on its streets, and obvious signs of infrastructural decay (roads in disrepair, for example), and other obvious signs of social decay (panhandlers, open drug use), which suggest a neglected social infrastructure. Maybe things have gone downhill in Tokyo since her remarks, but they have also gone further downhill here.

  This article in the National Post (by Barry Hertz) should be read in conjunction with some of the other commentaries appearing on infrastructure, whether on Richard Florida’s blog, or on the CEOs for Cities blog, or even on Doc Searls’s blog (see his recent piece, Handbasket weaving on the Berkman blog, or his infrastructure-related pieces in Linux Journal).

  I think the basic message is that this is not a question of “style” or edginess or cool or whatever, and it’s not even a question of tourists.  It’s instead a question of underfunded infrastructure, which is crumbling around our ears, and the resulting shabbiness is a symptom of that bigger problem. Underfunded cities and underfunded infrastructure has long term deleterious economic impacts.  The tourists staying away (or not staying as long) is just the tip of an economic iceberg.

• Digital Urban: Welcome to MapTube from CASA: A Place to Put Maps

  “The main principle of MapTube is that shared maps can be overlayed to compare data visually. For example, to see a map of the London Underground overlayed on top of a map of population you simply go to the search page and enter the keywords “tube” and “population”. Then click on the two relevant maps to add them.”

  This has potential for some really fine-grained mapping, specific to local place.
