Click2Houston is now reporting that the garage at Elgin and Milam streets behind the 24 Hour Fitness at 3201 Louisiana St. “sustained heavy structural damage” after 3 cars parked inside caught on fire this morning. The confusing sounds of popping tires had some bystanders running for cover as flames were blazing, a reader tells Swamplot; with the fire out now, police are on site, along with 3 fire marshal Priuses now parked along Milam.
Framing of the new “Jewel Box” on-garage drive-up pad site Galleria add-on has begun. A reader sends in this view from above, showing how the building has been perched onto the next-to-top level of the Blue Garage, which underlies the mall’s parking-lot approach from Westheimer. Westheimer runs from left to right at the top of the photo.

COMMENT OF THE DAY: HOW ABOUT A NEIGHBORHOOD PARKING POOL? 
“If businesses want to lessen their on-site parking requirements (once you get inside the Loop, they ALL do), my vote is that we should let them pool parking. Organizations could be set up that are similar to a MUDs but that build and maintain central parking garages instead of utilities. Businesses in the GD (Garage District) have their parking requirements taken care of by the central parking garage — they just need to confirm that there’s capacity through a letter of availability. This would allow for the car-less density that we’re after Inside the Loop; it would make it a lot easier to develop there, but it would also prevent parking from being a problem.” [ZAW, commenting on Coltivare’s Patio Wrap Draws Attention from the City] Illustration: Lulu
Occasional downtown parker Monica Savino notes the recent traffic signal now operating outside the north exit of the Hobby Center parking garage facing Rusk St. just west of Bagby (pictured above and at left), and wonders how other midblock parking garages with difficult exits might be able to get in on this kind of automated car-stopping action: “I’m sure it’ll be very helpful for that mass exodus after an event but was wondering about a couple things. How does a parking garage get its own traffic signal? Also, who funds this infrastructure? Is this a private initiative or a CoH move? I imagine that there are several other downtown parking garages that would like a signal of their own especially if the City’s providing them.”

Remember the fire back in March at those apartments under construction on West Dallas next to the cemetery that destroyed the whole complex except for the parking garage? No big deal if you don’t, because you’d need to adjust your memory anyway. A reader notes to Swamplot that the surviving parking garage is now being demolished as well, months after the singed stick-frame structures around it at JLB Parters’ would-have-been Axis Apartments were carted away. So now you can remember the fire so bad they had to tear the whole thing down — though it took them a while to give up on the garage.
Earlier this month, Houston First showed off renderings of the office building it’s planning to build for itself and 3 other Houston-boosting organizations (top), headlined by the Greater Houston Partnership, one block north of and linking to the George R. Brown Convention Center. (A massive attached 1,900-car parking garage would share the skybridge to the George R. Brown and fit between the building and the Hwy. 59 overpass.) Yesterday, the operator of the city’s performing arts and convention facilities pulled out an additional pic (above), highlighting another aspect of its plan, and showing how the same building would look with a 15-story add-on perched on top of it. The rendering of the tower portion by WHR Architects, the same firm that’s designing the office building and parking garage, is meant to be “conceptual”; Houston First announced it will begin taking proposals for the hotel from developers, who might choose a different design team.
The 10-story office building announced earlier this week for a site across the street from the George R. Brown Convention Center won’t just house the Greater Houston Partnership, for which the project is being named; it’ll also be home to a swell crowd of quasi-governmental city-boosting organizations, whose members will gladly walk you out onto the 2-story 2,000-sq.-ft. upper terrace at the corner of Rusk and Avenida de las Americas, slap you on the back, and point out all the new buildings and visitors and conventions swarming around Discovery Green.
If it isn’t too late in the afternoon (the deck faces west), a city scout needing a little convincing or glad-handling will have an eye-opening view of Houston to behold: A slice of Houston’s central, quasi-public park with its suggestively undeveloped surface parking lots and the rest of downtown beyond, bookended by the city’s 2 remaining non-acronymed sports facilities, Minute Maid Park and the Toyota Center. Kinda stepping in front of the center portion of that view will be the new Marriott Marquis currently under construction along the combined Walker and McKinney streets on Discovery Green’s eastern flank, but the hotel’s tower portion will be shifted a bit to leave room for a park overlook. In a nod to the marketing world’s recent fashion of mildly gritty cité-vérité, the new office building’s deck won’t be air-conditioned, but the nearby towers should generate a fair amount of breeze, and its height should put it safely above Houston’s 8-story mosquito line.
COMMENT OF THE DAY: A STRUCTURAL ENGINEER EXPLAINS PARKING GARAGE COLLAPSES 
“. . . Structural design is generally done by computing an anticipated load (how much will the stuff in the building weigh?), multiplying that by a safety factor, and then designing a structure with enough strength to support that “factored†load. Modern building codes also estimate the anticipated strength as less than it actually is too (for errors in materials/construction). Structures generally end up with at least 3 times as much strength as they need. That said, parking structures typically have the lowest factor of safety built into their design. They fail much more often than other building types because a) they’re so cheaply constructed, b) the loading is so much lighter than other types of structures that factoring doesn’t increase the loading by as many tons, and c) failure rarely results in loss of life.
@TL: You mentioned that there was a loud creek and then it failed? Any guess how long that creak lasted? 5 seconds, 3 minutes, an hour? I ask because concrete structures like this (ESPECIALLY pre-stressed concrete structures) are designed so that IF they fail, the rebar in them is the last thing to go, which will stretch and stretch and stretch gradually so that people have a chance to GTFO. The alternative is what’s called a brittle failure, where there’s just one loud pop and then bam; no warning at all.
. . . Engineers always talk about this stuff in terms of ‘strain’ and ‘yield.’ Strain is how much a material can deform (stretch or compress). When the strain gets too much, the structure ‘yields’ or permanently deforms. For a concrete structure, deform === collapse. The last thing to go before a concrete structure collapses is the reinforcing steel, which has a maximum strain of about 0.02 (2%) before yielding. That means if the clear span (beam-to-beam distance) is 30 feet, you can have a sag of 30 ft / 2 * 0.02 = 3.6 inches before it actually damages the structure. Parking garage widths are typically 64 feet, which can have ~7.5 inches of sag in the middle.” [Ornlu, commenting on A Top-Down View of Last Night’s Parking Garage Collapse at One Riverway] Illustration: Lulu
A Swamplot reader writes in with a report on the aftermath of last night’s collapse of a top-story section of the very long parking garage for the One Riverway office building north of the Galleria, on S. Post Oak just south of Riverway Dr. No one was hurt in the accident, which occurred before 8 pm, but abc13 reports that vehicles were still exiting the structure at that time. S. Post Oak Ln. is now closed to traffic while officials determine if the concrete structure is safe, and workers are already mourning the lost parking spaces.
“The doors do actually open on that floor and the elevator is functional,” insists the Swamplot reader who sent us these photos of the elevator landing on the fifth floor of the attached parking garage for the Decorative Center Houston at 5120 Woodway Dr. north of the Galleria. Yes, getting in and out would likely be a little difficult for those wider of girth or packages. But if you do end up stuck, you can always go down to a lower floor, switch cars, and come back up where there’s a little more space to maneuver:
Here’s a view of the Wedge International parking garage at 777 Clay St. from across Polk St. taken yesterday. It’s not particularly notable — until you realize what’s no longer visible. For years, while a surface parking lot stood on the lot in the foreground, this was the scene of Houston’s most spectacular grid of auto headlights and taillights — changing daily, and screened from their cliff-like views at each level only by low, light-looking barriers of steel cables. (A closeup side view of the scene from last week, with a few levels already partially masked by new chain-link fencing, is shown at right.)
COMMENT OF THE DAY: A DEALCHASER’S GUIDE TO MONTHLY GARAGE PARKING DOWNTOWN “Do we need more parking downtown? Um, yes. Corporations have bought up many garages and left nothing for everyone else.
I work in the Wells Fargo building, where an unreserved spot costs $400/mo. I had a spot in the Travis Place garage for $150, but Kinder Morgan or El Paso bought all the spots. I got a spot at 919 Milam for $190-ish, and some tenant bought all those spots. Then I got a spot above Pappas BBQ at 1100 Smith, but they kicked out a bunch of parkers (including me) to open up spaces for new tenants at 1100 Louisiana. I tried to get a spot in the Theater District garages, but they have a wait list a mile long. So now I’ve moved to Two Shell, which is $215/mo. Renovations are about to begin there, so I’ll either get the boot again or it will become prohibitively expensive. (Again, all of these prices are for plain-jane unreserved spots. And I can’t take the bus because I am in and out of the car all day.)
So, yes . . . We need more non-corporate parking downtown.” [Montrosian, commenting on Downtown’s New Highrise for Cars Is Going Up!] Photo of Wedge International Tower parking garage: Swamplot inbox
Construction has begun on the 16-story, 1,600-car parking-only highrise at 1311 Louisiana St. When complete, it’ll cover the northeast half of the block surrounded by Polk, Milam, Louisiana, and Clay, and provide layers of automotive insulation for the cars up against the ropes (and more recently installed chain-link fence) on the adjacent Wedge International parking garage. In the meantime, Wedge parkers will have a decent view of the construction activity below.
It appears that Gensler has submitted for review by the city planning commission this rendering of a 1,600-space, 16-story parking garage. Maps included in the agenda for the October 3 commission meeting show that the garage would stand Downtown at 1311 Louisiana, now a surface lot, and share the block bound by Louisiana, Polk, Milam, and Clay with the 12-story garage for the WEDGE International Tower.
IN PRAISE OF CARNEGIE VANGUARD’S MIXED-USE PARKING GARAGE 
What does HISD have to show for that $805 million approved in 2007 for new school construction and renovation? MaryScott Hagle reviews the results at Lockhart, Herod, and Peck elementaries and gives props to RdlR Architects for the design of Carnegie Vanguard High School at 1501 Taft — though she seems most taken with the parking garage, which was, she writes, “originally planned for one story that grew to two when the City of Houston offered to pitch in, in exchange for community access to the school’s ball fields on the weekends. . . . Furthermore, the garage itself is dual-purpose: when the academic day is over and the students who park on the garage roof go home, the Carnegie tennis team takes over for practice.” [OffCite] Photo: HISD
