  1. not important until the RFIs start coming in LMAO - engineer
  2. if they are going to include a bridge for the BRT at least add a couple of lanes for car traffic, that train track always has stalled/waiting trains that disrupt traffic in the East End
  3. cheap...but just like anything ethnic nowadays....gentrification LULZ
  4. Dora the Explorer? and you want us to take you seriously? come on dawgg
  5. id recommend reading the book Houston Electric by Steven M Baron.....awesome info on Houston's old electric streetcar system
  6. engineer here, these comments help me understand how architects think....completely different from us lol
  7. We don't need a 50k stadium, yet. Just need to win consistently to bring the fans back.
  8. depending on the TxDot District, most design work is done by consultants....some, like Houston District, design some of their stuff "in-house"......Tunnels cost A LOT more than bridges (especially here with the soil type) and there's barely enough infrastructure money as it is...there's all sorts of infrastructure underground (storm sewers, water lines, wastewater lines, ets)...there's a reason you have to call 311 before digging....LULZ
  9. bridge girders/foundations are probably going to be designed for truck loads, not rail loads...gonna need some serious retrofit/$$$ after....unless someone can design a really, really lightweight train/tram
  10. i knew i had it seen it before in the standards, i need to do more low speed bridges...found a TxDot rail standard for an aesthetically pleasing rail https://ftp.dot.state.tx.us/pub/txdot-info/cmd/cserve/standard/bridge/rlstd021-20.pdf
  11. I'm sure the required hydraulic opening of the original bridge design (open area under bridge) is much, much lower than what is calculated now (newer rainfall data, more construction upstream of the bayou/more stormwater runoff). https://www.projectbrays.org/all-segments/segment-1/about-telephone-bridge/ https://bridgehunter.com/tx/harris/bh50785/ This bridge is from 1931!! Great service life. I like the old school rails on the bridge tho, i wish we constructed more similar rails in TX. We cant because of the traffic rating required at high speeds.
  12. Yes, in bridge design, the bridge engineer doesn't change the road profile (difficult to change in urban areas), so the deeper beam will create less area under the bridge for the water to flow. More area was added (thicker bridge) to impede water flow than was removed by taking out a couple of bents. However, less bents is also good because it prevents debris from being trapped at the columns and impeding water flow. It takes just a couple of iterations to get it right. Also a lot of the new bridges are being built with recently updated rain/hydraulic data.
  13. Here in Texas, the "row of columns" are called bents, in some other places in the country/world, they're called piers. The first and last bents of a bridge are called abutments. The number of bents is determined by superstructure type (CIP slab, slab beams, box beams, concrete i-girders or steel girders) and hydraulics of the stream. The bigger the beam, => the longer the span, => the less number of bents, => the deeper the bridge, => the less space under the bridge for water to flow. The water flow through a bridge is calculated by hydraulic engineers who determine whether the bridge needs to be raised or extended to accommodate the water flow.
