This week I saw it reported that in this decade alone, the Seattle area is set to deliver more new rental apartments than it did in the prior 50 years combined.
And as a result, the sentiment is that new housing supply is finally starting to keep pace with demand and put downward pressure on rents.
Do you remember who was the crane capital of the US a year ago? They may still have that title.
In some of the most desirable neighborhoods of Seattle – where much of the new supply is coming online – rents dropped 6% compared to the prior quarter. At the county level, this last quarter was by far the biggest drop of the decade according to the Seattle Times.
Funny how that works.
It’s also worth noting that the US as a whole is building far more rental apartments than condominiums. Here is a post I wrote in August 2015 which pegged condos as a percentage of overall multifamily construction at around 5.5%. That’s a tiny percentage.
Alexis C. Madrigal recently published a piece about the Salesforce Tower in San Francisco called: The Tower at the Heart of the Tech Boom. At 61 floors and 1,070 feet, it is now the tallest building in San Francisco and the second tallest building west of the Mississippi River after the Wilshire Grand Center in Los Angeles.
Hines and Boston Properties are the developers of the building. Pelli Clarke Pelli is the architect. And Salesforce is the anchor tenant. In April 2014, it was announced that they had leased 714,000 sf on floors 1, 3-30, and 61. (Get that top floor.) So almost half of the building.
Perhaps not surprisingly, Madrigal calls the Salesforce Tower the “the most visible monument to the industry [tech] in the region and the country.” It is a demonstration of the power and reach of Silicon Valley. San Francisco has a new symbol. The TransAmerica Pyramid now feels inadequate.
Though interesting, this is actually not what I want to talk about today. I’d like to talk about what it took to build such a tall building in a seismically active city like San Francisco. Unfortunately, this feels timely given that the sinking Millennium Tower is getting so much attention right now.
The structural engineer for the Salesforce tower is Seattle-based Magnusson Klemencic Associates (MKA). They are a world-renowned structural and civil engineering firm that have been around since the 1920s. Other projects they are currently working on include the third tallest building in Chicago.
The tower’s seismic force-resisting system is made up of reinforced concrete shear walls that surround the central elevator and exit stair core. These walls are 24 to 48 inches thick. Here is a plan taken from
This week (Thursday) was the deadline to submit proposals for Amazon HQ2. About 100 cities across North America are thought to have a bid in.
New York lit up every single landmark in the city with “Amazon orange” in an “embarrassing attempt” to try and win this thing. That’s how bad cities want this.
I already think that Toronto has won an incredible prize with Sidewalk Toronto. Arguably, it may turn out to be more impactful to this city than Amazon HQ2. It’s an opportunity to define the future of, not just this city, but all cities. It’s an opportunity to lead.
At the same time, I continue to believe that there’s no better place for Amazon HQ2 than here in Toronto. Not surprisingly, our bid emphasized the point that I’ve been hammering home on this blog since Amazon first announced the RFP. Toronto’s key competitive advantage: talent.
Below is an excerpt from the submission cover letter. The entire letter emphasizes our ability to grow, attract, and retain top talent.
Thirty-nine percent of the Toronto Region—and 51% of Toronto proper—are born outside of Canada. We welcome more new immigrants each year than New York, LA, and Chicago combined. We speak over 180 languages and dialects. Toronto is heralded as the most multicultural city in the world, and our labour force and economy benefit directly from our diversity and inclusivity. We build doors, not walls. And those doors open to highly-skilled economic immigrants and international students who can easily become permanent residents and citizens.

Okay, enough about Sidewalk Labs and Amazon. Regular scheduled programming will resume on the blog starting tomorrow.

The tower’s foundations have been well documented, or at least frequently mentioned, because of how deep they had to go down. The site has poor soil conditions (fill, sand, San Francisco “old bay clay”, and weak bedrock), and so given the weight of the tower the only option was to go down to bedrock – approximately 250 feet below grade.
The foundation system they ended up going with uses something called Load-Bearing Elements (LBEs). The typical LBE measures 5′ x 10.5′. The entire foundation system uses 42 LBEs and a mat foundation that varies in thickness from 14′ around the core to 5′ around the perimeter. (See image below.) The LBEs were brought down to rock. And in some cases, they went down more than 310 feet below grade.
As a condition of buying the site, the Transbay Joint Powers Authority required proof that any future tall building would not negatively impact the surrounding structures – including the adjacent Transbay Transit Center – and that it would perform under a Maximum Considered Earthquake (MCE) event.
So while the tower itself may be a symbol for the new world, its structural system also achieves many firsts in terms of how to build a supertall in a seismically active region.
Please keep in mind that I am not a structural engineer. I just pretend to be an architect sometimes. If you’re interested in more of the details, check out the post by Ron Klemencic. All of the above information was taken from there.
