    This project is baddass. ConstructionPorn for sure. Well organized project site. Nice pictures nate. If I may ask, are those a few office windows staged ontop of the shed (PM office maybe) to the right?

    http://en.wikipedia.org/wiki/The_Spirit_of_Houston Google image search spirit of houston statue. Kind of amusing statue, that never got built.

    Construction companies aren't going to easily divulge that information to their competition for private ventures like this. Labor rates, Material costs, and productivity rates vary between companies, and the last thing you'd want is for your competitor to undercut you in an open bid. That beings said, while you may not be able to find specific cost estimates for skyscrapers going up now. You might be able to find some on older and perhaps more famous structures around the world.

    Very impressed with the aluminum framing and construction.

    agreed. Looks like they also installed little sunshades over the windows. I'm glad, it gives the building a little more 'texture'

    For what its worth, the law ( states that you must file with the FAA if your structure meets one of the following: 14 CFR Part 77.9 states that any person/organization who intends to sponsor any of the following construction or alterations must notify the Administrator of the FAA: any construction or alteration exceeding 200 ft above ground levelany construction or alteration:within 20,000 ft of a public use or military airport which exceeds a 100:1 surface from any point on the runway of each airport with its longest runway more than 3,200 ftwithin 10,000 ft of a public use or military airport which exceeds a 50:1 surface from any point on the runway of each airport with its longest runway no more than 3,200 ftwithin 5,000 ft of a public use heliport which exceeds a 25:1 surfaceany highway, railroad or other traverse way whose prescribed adjusted height would exceed the above noted standardswhen requested by the FAAany construction or alteration located on a public use airport or heliport regardless of height or location.Source https://oeaaa.faa.gov/oeaaa/external/portal.jsp Obstruction Evaluation / Airport Airspace Analysis (OE/AAA) 200 ft. above ground level is pretty much every mid level and major skyscraper in Houston Proper. I think the so-called "defacto" height restrictions by the FAA some are proposing here appears to me to be more of an urban legend. Especially if the structure is in downtown... surrounded by several 800 foot plus skyscrapers. I think you'd have more truth to the argument if Hobby was closer to downtown. But theres a lot of cities with airports, closer to their respective downtowns and they don't have issues with large structures going up. Midway airport is 10.2 miles from Downtown Chicago. Hobby airport is 11.2. La Gaurdia Airport is 8.1 miles from Manhattan (more specifically central park). Logan Airport is 4 miles from downtown Boston. The list goes on... The reason supertall skyscrapers dont get built in Houston, I'd opine, probably has more to do with the economics of the region than with a small(er) international airpot 12 miles away.

    Windows need to have Chevron Hatching with a chevron shaped crown at the top. It would be like inception. Chevron within a Chevron within a Chevron.

    Careful guys and girls, we've got an internet tough guy here.

    The design changes rumor puzzles me. Thats an expensive-ass change order for a 'Redesign' of a 4-5 story building. Call me skeptical of that rumor. I'm wondering if they had QA problems or material problems on their concrete.

    From 610, the updtown/Gallery skyline looks very dense. From the air, not so much. Love that view though.

    Theyre waiting on the next forest to grow so they can cut it down: Need more lumber
  12. Purdueenginerd
    ah okay. Thanks.
  13. Purdueenginerd
    How long has that wood framing been exposed to the elements?
  14. Purdueenginerd
    Those are some pretty good renderings.

    I noticed they had replaced some of the diagonal bracing with new steel the other day. Must have been damaged or corroded.
  16. Purdueenginerd
    ah, that makes more sense Cloud! Thanks.

    Ross Perot!? I didnt realize he was still around. Great Photos Howard & Nate

    I like brick for highrises more, in my opinion. It looks better than the glass over the course of decades.
  19. Purdueenginerd
    You COULD get away with it, with some strengthening. If its a simply balcony the requirements arent that much, but if its a gathering space for large groups of people, then yes. The requirements are high.

    That guy is lucky to be alive. Falls are one of the most common sources of fatalities at the construction workplace. OSHA regulations call for the requirement of Fall protection if the worker is at 6 ft (in construction) elevation above the local walking surface. At 15-20 ft, the distribution of fatal falls is quite high. Some light reading for those bored: https://www.osha.gov/dep/fatcat/fy13_federal-state_summaries.pdf https://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=STANDARDS&p_id=10757 http://www.cdc.gov/niosh/docs/2000-116/pdfs/2000-116b.pdf

    Luminare brings up an excellent point. This project doesnt have as large laydown yard for material as some of the other projects in Downtown. This affects the ordering and storage of materials needed for construction, which can make scheduling and project management more cumbersome and tedious. Also, the joke earlier about the truck probably does have some credence. I know if I was engineer of record for this project, and a truck hit my structure like it did, I'd hire a 3rd party engineer to perform an evaluation of the 'damaged' area before proceeding.

    I apologize nate, I didnt see the purdue signal earlier in the week. ASTM D1143 Static Load testing of Piles. We happen to have the ASTM Standard in our library and read over it (its a slow friday). But I found a digital copy for you online, if you'd like to peruse if youre bored. http://www.powerliftfoundation.com/wordpress/wp-content/uploads/2014/08/ASTM-D1143.pdf (PDF warning) Basically its a Geotechnical Engineering test for Piles. Pretty cool catch on the photograph!

    You can scale it using the fall barricades if you're bored. Those are probably 2x4s (which have dimensions of 1.5x3.5) and theyre probably around 3-4 feet tall.

    Theyre finally putting up windows on the side facing 45 & Downtown.
