    Right now we have over 1000 apartment units on the drawing board or under construction in downtown. There are currently just under 3000 total living units in downtown Houston. My guess is that a 33 percent increase in people living there will be followed by a small retail boom. Hopefully the housing construction continues and more people move into downtown

    That's awful. Safety lesson: the construction industry had 775 fatalities in 2012. 280 of those were fall related. Always 100 percent tie off when working at unprotected elevations of greater than 6 feet. 45 percent of falls under 20 feet are fatal. And even at 6 to 10 ft the rate is 11 percent fatal. Falls account for the 3rd highest workplace fatality rate --- behind homicide and roadway accidents. I shared this article with my companies safety team. We had an hour long safety stand down at our construction sites to discuss the importance of 100 percent tie off.

    Nice size residential building. My apologies if this has been answered, how many apartment units are they planning for the site? /edit: nevermind- 289 units listed on the PDF

    So many blue glass high rises! Architects need to diversify their photoshop painting skills!

    Looks like a well lit strip club to me

    Hey! Shopping is pretty exciting for some people... especially on Black Friday

    I was going to go into a long an elaborate post: but wikipedia will pretty much cover what you need to know http://en.wikipedia.org/wiki/Tunnel#Construction

    I have several friends who are employees of exxon. All in their 20s. Their reactions range from "moo" To "I dont like it" Anecdotal evidence considering all of them live in Midtown or downtown....

    I think using the HAIF population is not a statistically representative body of people. All of us here are interested in Houston's architecture. The impact of a suburban campus versus a downtown, skyline changing highrise are of course going to warrent more discussion towards the latter. That being said, I still prefer the Chevron plan.

    Chevron's Revenue is 241 billion dollars per year. Net Income: 26 billion dollars per year. This building, is cheeeeeeap!

    Project Bluish Glass tower number 250! C'mon architects, pick a different color in photoshop!

    Look at post number 151. Thats your form work. The truss elements are only 3-4 feet tall (hard to tell because of the fish eye lenses). You can also tell from the picture theyre not (completely) assembled for the entire floor. As to how they work: Components are assembled together before hand to form a gang form. A gang form is typically defined as a group of unit forms tied together and lifted by crane to the proper spot. They probably have a crew assembling the gang forms on the ground, or offsite. Crane lifts into the correct spot, Concrete pour occurs after rebar placement, and after sufficient curing (not drying) then the components are broken down again, staged, and flown (slang for lifting with crane) down to the ground where the process is repeated. They probably have enough formwork for more than 1 floor, so while things are being staged to take down to the next floor, they probably have the gang forms for the next floor ready to go. Here's a video on how they do it for wall construction: Keep in mind, the dissembling process for wall construction may be different than slab construction. Now, I dont know their formwork system or civil design. So what i'm saying is a bit speculative on my part. Please keep that in mind.

    Modular formwork (premade formwork). Yep that'll speed things up.

    Just a correction guys. The FAA doesnt have any power to shut down a project. What happens is the FAA will look a proposal and indicate if that will force them to alter approach and departing vectors to stay within FAA guidelines. If a new building will alter pathways for the airport; it can affect commerce out of that airport in a detrimental way. Normally; at this point Governments will step in and say, "yo-change this building design". The building developer doesnt have to listen to the FAA; they may however listen to the government.

    That building would be pretty baller if it was the tallest in the city. It would look great from every angle around downtown... IMO.
  18. Purdueenginerd
    Where'd you get this rendering?
  19. Purdueenginerd
  20. Purdueenginerd
    Woo. Looks taller than the 1600 Smith Street High Rise (continental airlines building). If rendering is correct, that puts it more than 730 feet.

    Reminds me of the Westin Hotel in Downtown Memphis, TN

    Very nice. In my opinion, an upgrade over its current appearance--- which I'm not a huge fan of. My question is, is this an architects weekend project that were seeing or is there substance to possible renovations?

    Honestly, If you look at the actual skyscraper component the dimensions of each slab look like around 120 x 75. or 9000 sq foot slab. (http://wulfe.com/Realister/Manager/Property/Skyhouse%20Houston/PDF/Skyhouse.pdf) As context, I work in industrial construction---which is vastly different than commercial construction, so if anyone wants to chime in and correct me... by all means do it. My closest experience was on a coker turnaround (http://en.wikipedia.org/wiki/Delayed_coker) where we replaced the entire coker head deck. That was 6000 sq feet. We had to demolish with jackhammers the existing head deck, assemble quite complicated formwork, Place rebar for a 750 PSF two foot thick slab (For comparison, a residential slab would be around 50-100 psf and be in the thickness range of 6'' to 1'), and pour concrete. We did it in about 5-12 hour shifts. ---Including the demo and debris removal. The whole thing depends on manpower though. For my aforementioned project I think we had 75 men scoped for that project (including management and logistics support). Is skyhouse work crews working around the clock? How large and experienced is their crew? Is the financier willing to pay the OT associated with round the clock work? Archfan brings up a good point though, I really dont know if the company building is just a GC or if theyre using their own labor. Good point. Disclaimer: All of this is speculative and intended for conversation only

    They could put retail on the first floor and have the garage behind it. Thats what skyhouse is doing with their north retail area. However, I'm being merely speculative.
  25. Purdueenginerd
    I'm "guessing" part of the reason its going up so fast is because they've built it-- 6 times? Hey, cost effective I guess.
