IS OUR NEWSLETTER SO INFLUENTIAL?

Who would have thought that our bite-size structural news e-blasts have such a powerful impact? I’m sure you remember the story I wrote about my “pet project” — how dangerous the soft story buildings are in Los Angeles and that the city of San Francisco has enacted an ordinance to upgrade about 2,000 such buildings. I had discussions with many of my readers, who responded to my article, agreeing with me about the necessity of similar action by our own city council. One of the architects, Mr. Doug Breidenbach, AIA, with whom I’ve been doing business for a few decades, has an inside track to city councilman Mr. Karo Torossian and his office. Recently he spent considerable time meeting and discussing the necessity of similar actions with Mr. Torossian.

Here comes the break-thru. Another Los Angeles city council man, Mr. Tom LaBonge, who is also concerned with the situation, has just requested, by a motion, that the city council consider instructing the Department of Building and Safety of Los Angeles to provide an inventory of thousands of these so-called soft-story buildings. An inventory is the necessary first step of identifying and cataloging these buildings to see what impact these would have on the safety of the citizens of Los Angeles, particularly the people living in them. Just a reminder, during the 1994 earthquake 16 people died just in the Northridge Meadows apartment alone. That’s only one building! And it was all due to this soft story style building.

One thing that must be considered is the economic hardship on landlords to retrofit these buildings, and how these costs can be mitigated by ways of tax incentives, federal grants or having the costs of this construction be passed onto the tenants living in those buildings.

Very interesting development, our office will follow up and report on this topic as it develops.

H/3 – A CAUTIONARY TALE

We are very much into real estate frenzy, as you know. In the last 8-12 months we’ve heard many stories about bidding wars, properties sold over the asking price, etc. Some people, afraid that they might lose out on yet another dream home, aren’t doing the necessary background checks for the property they want to buy, or actually end up buying. Usually home inspectors bring up the obvious problems with a house, but the costly and most important structural issues can remain undisclosed. I want to bring up a very common situation our office faced several times recently, so it appears to be “trending”, as they say.

Building laws for hillside properties have changed drastically since the 1994 Northridge earthquake. Our office was involved in over 400 home structural inspections and helped the local Building and Safety departments to craft new “Hillside Ordinances” to avoid the most common hillside construction problems. There are several related new building laws, but I think the most important is the H/3 rule. This rule requires the foundation of a new construction, or remodeling of an old one, on a hillside to be of a minimum depth, without consideration of the underlying soil characteristic, based on the height of the existing slope only. Without going into the technical details, foundations on hillsides, without exception, have to be on deep piles – sometimes 40, 50 or even 60 feet deep.

Recently our office faced the unpleasant task of explaining to a few new home owners that their proposed addition on their recently purchased hillside property would be much more expensive than they thought at the time of the purchase of the property, because of this H/3 rule.

My advice is to consult a soil engineer, or structural engineering company, or have an approved, recent soil report included in the contingencies of the purchase.

Test Loading of Elisabeth Bridge, Budapest, Hungary in 1964

Source: erdekesvilag.hu

“I remember in my younger years, before I became an engineer that a bridge was built over the Danube in Budapest. It was a suspension bridge and slowly but surely the pieces came together hanging from the suspension cables and the bridge was finished. Before it was given to the public for use, a test loading had to be done. One by one trucks fully loaded with sand, buses, street cars and all kind of heavy equipment rolled on to the bridge. The sight was awesome. The bridge was deflecting, stretching, bending to the limit. But the sight what I’ll never forget was this. The chief design engineer of the bridge was under the bridge alone, moored in a tiny dinghy on the water, showing the whole world that his is putting his life on the line for his design. Now that’s what I call responsibility. It started with the first known building law, Hammurabi’s law about 5,000 years ago which stated: “If a building collapses and the owner’s son dies, the builder’s son must be put to death”. Serious stuff…”

HERE I GO AGAIN!

If you’ve been reading my newsletters for a while, you know my pet peeve – soft story buildings. For Los Angeles, all the neighboring cities and for all of the state of California it would be so much safer by retrofitting these buildings. The issue is, as always, cost and incentives.

Last month, I participated in a think-tank meeting for seismic related issues in the Los Angeles area. Among other things — like geology, seismic preparedness, seismic faults, etc. — the soft story issue came up as one of the most pressing items for structural engineers recently. One of the panelists was Lucy Jones from USGS, who was recently hired or “loaned” to the city of Los Angeles to help the city put together a list of under reinforced concrete high-rise and “soft story” buildings. You could see her on TV rather frequently answering questions about the recent La Brea earthquake. She is known as the Earthquake Lady.

There were suggestions for mandatory upgrades by new city, county or even state ordinances, state bonds to finance construction — because actually this is more of a state, than city problem — tax incentives for landlords, etc. All of these have been discussed before, but one suggestion stood out and it wasn’t mine. Dog gone it!

For departments of public health, health inspectors go to restaurants and grade them for cleanness and other health related issues. The restaurants get an A, B or C and those placards have to be posted at the entry of the restaurants with big blue letters. Restaurant owners were so much against it at the beginning, fearing a loss of customers. Today it is a normal thing to check out a restaurant’s grade. I know that I wouldn’t eat in a restaurant with a C rating. The bottom line is that restaurants really got much cleaner since this system came into law.

Why not to do a similar action for apartment buildings? Apartment owners and landlords are already paying a yearly fee for inspectors to check out the apartments for health and other issues. It would be simple: make landlords post a sign issued by the local Building and Safety inspectors on the front elevation of the building indicating that this building is a dangerous place to live in. This would be a tremendous incentive for landlords to upgrade their buildings in fear of losing tenants.

No mandatory upgrade, no political issues, no deadlines, it would be voluntary only.

Problem solved, and in a few years the majority of soft story buildings would be fixed.

The biggest questions is, of course, why didn’t I think of that?!


What do you think? I’d love to hear your thoughts on this.
