Thank you for the advice! The links were useful.

Also by any chance does anyone know the difference and significance of the FAA's taxiway design group (TDG) and airplane design group (ADG) and which one should be used for proper runway/taxiway/taxi lane dimensions? The terms can be found in the main FAA airport engineering manual (5300-13A) but I am not sure if I should be using ADG of TDG. Thanks.

Hello, I would assume a lot of people have seen my previous posts about me trying to design an airport. I am currently doing well but starting to design the terminal. I know what basic concept and shape it needs to be, but I am having trouble with the dimensions- I know the building needs to be large enough to process a certain amount of passengers but also not too big. I do not know how to make the building with proper dimensions. The terminal which I am designing has one large building with piers that connect to the gates. The main problem is that I cannot predict peak demand or seasonal demand, as well as hourly demand or forecasts since I do not have computer simulation software (I'm in high school). However, I have limited information regarding passenger demand. The airport in its first phase is to handle 5,000,000 passengers. I also found some useful information on the FAA website: (Rules of thumb) (1) Either peak hour enplaned or deplaned passengers may be assumed to represent approximately 60 to 70 percent of the total peak hour passengers. (2) Peak month passengers may be approximated as 10 percent of the annual passengers. (3) Average day-peak month aircraft operations may be estimated as 1.05 times the average daily activity for the year. Can I use this information to design the basic dimensions of each part of the terminal to be suitable and spacious enough, or should I go by estimates (which would more than likely be inaccurate)? How do I decide the dimensions? Any and all suggestions welcome. Thanks.

I actually decided to use the proposed on land site and base my airport off of the proposed site, but thank you for the suggestion!

I will definitely consider a larger distance- there are many open undeveloped areas outside the city. Thank you for all the help.

I have been trying to find a marine depth map- is there a specific threshold that makes it too deep to build? Is there anywhere where I can find that sort of information? Both lakes I see north of Chennai (one is called Pulicat lake) I think are too far north from the city center. Also, I think another realistic factor would be to connect the new airport directly to the metro that the government is currently trying so hard to build. I was thinking near the northern tip of city limits (the farthest point of the metro) assuming that land disputes would be settled (or is that too stretching it too far?).

I think I have to go with a runway parallel to the existing airport's one because the old airport definitely cannot be discarded; it currently going through a huge modernization project which would mean it is unrealistic to simply discard it. Even if the new runway juts out into the ocean I am assuming it would only increase the cost and not pose any other major issues as far as I am concerned.

I am definitely thinking Chennai because I have been there multiple times and I think the personal experience would definitely help with the project. I am not doing the skyscraper; this idea is much better. Do you mean parallel to the existing airport's main runway or just parallel to the shore? The thing with parallel direction is that the existing airport's main runway is 07/25, meaning that if a new airport were to be built on the shore parallel to the existing one then the runway would jut out in to the ocean. If built parallel to the shore, it may pose problems for the existing airport's approach path because even for aircraft coming in from the west they must fly past the airport, turn around, and land from an eastern direction. I am not sure if there is an easy way to rework the existing flight path to accommodate the new airport if it is built parallel to the shore, or if it should just be built parallel to the main runway of the existing airport. As far as I know, I do not think there is a well known study for an airport in the ocean. Thank you for the help.

In recent years the explosive growth of cities such as Mumbai and Chennai in India has lead to proposals for new airports to alleviate the stress and congestion at existing ones. Chennai airport, for example, currently handles somewhere near 14 million passengers and will be saturated within a few years; it already faces numerous physical restrictions such as well as government regulations that prevent it from expanding properly. A new airport is definitely needed and building it on land would mean it would be far from the city center, and past examples (e.g. Montreal Mirabel) show that airports that are far away and lacking connections to the city center can easily become huge infrastructural failures. An airport could be built out at sea, which is a realistic solution due to the lack of free land on already expensive and densely populated shore. An offshore airport built would need to initially be capable of handling maybe 5 million passengers with an eventual need for expansion. Therefore, I am thinking of designing an airport as a science project. I am currently in high school, so I obviously do not have the resources to make a complete design. I understand these things are done by engineering teams who have done extensive research and preparation to even propose a design. That being said, whatever I end up coming up with will be somewhat general, addressing a limited amount of problems. I know an airport out at sea not only needs to be designed to efficiently handle passenger traffic but also be environmentally safe and structurally stable. It need to be reasonably self sustaining because of its location. I know that there are numerous other things that can be problematic for an engineering team faced with such a huge task, but unfortunately I do not think I am capable of addressing those problems because I do not have the knowledge. I am really interested in doing this project for whatever it is worth, but I am not sure if having something too broad will defeat the purpose of it. That being said, I think that there are two ways I can take this: 1. I can focus in on a specific problem that pertains to building a new airport (maybe what type of features it would need to conserve energy and water) That would also mean that I would be purely focused on how this building would need to efficiently use power and water rather than ho w many runways and what type of facilities it would need to handle passengers. 2. Go with a broad design that tries to address all or most problems in a vague manner (designing an airport and explaining possible features it would need to endure the conditions off shore), and not addressing some problems such as the stability of the seabed and protection from natural disasters This design would also be derived from existing off shore airports (e.g. Kansai or Nagasaki) Any suggestions ideas or guidance would be very helpful. Thank you in advance.

Hi everyone, Sorry for the lack of details that I have provided. At this point I am just throwing ideas around; I am yet to draw a sketch or set boundaries although I will be very soon. The project's primary purpose is to create an appealing design and include features that portray the concept as sustainable and green. This includes trying to address the problem of thermal autonomy, as well as trying to achieve independence from the electricity grid and water grid. That being said, it is more of a fantasy rather than a realistic simulation since I obviously do not have the resources/insight to make it the latter. To calculate energy requirements, I am assuming I would use the occupancy of the building along with average usage per person right? And for the climate control, would I have to find the volume of the air in the building and calculate the amount of energy needed to heat it? I think it is doable to design a building and write a paper the four-five weeks I have to complete this project. Is there anything I should be adding that would enhance the project other than what was suggested? Thank you so much for the information; it really helped clear up some doubts.

In the near future, I will be using a computer program (either Autocad or another good architectural software, likely the former) to design a very basic layout for a skyscraper for a project. In order to do this, I need to decide level of detail I would need. I am currently a high school student doing this for a science project, and I will be honest and say I do not have much experience designing buildings other than an introductory architecture course. Can I get away with a blueprint with dimensions or should I aim to design a full 3D model? Secondly, I need to decide dimensions. I am aiming for this to be a sustainable office building skyscraper that incorporates wind and solar power. I realize it would need to be slightly larger to accommodate these extra things. Is there anything that makes an architect/designer decide on a specific height/width/length or is it simply whatever they want to make it after considering structural stability and location? Any ideas/suggestions welcome. Thank you in advance.

I understand I do have a lack of specificity and details and I apologize, but I am still in the initial brainstorming stage. I appreciate the ideas and suggestions very much. Thank you for the help. I will take everything into consideration. Overall, is this idea too impractical or sophisticated considering I am at a high school level? I think most problems can be worked out without making the idea too quixotic. Thanks again.

I was considering a floating city, but I feel that there are already many designs out there and mine would not be very unique. Therefore, I think I am set with designing a building on land. Even if the skyscraper was similar design wise to the Bahrain World Trade Center, would it be unstable? Also, since I am also considering incorporating solar and nuclear power, I have a few ideas. Recently, transparent solar panels have been developed that could be used as windows, and possibly these could be used for power. The nuclear power, if needed, would come from a reactor contained underground, deep enough so a failure would not jeopardize the whole structure. I will also brainstorm some stuff for a shorter building; thank you for the idea. For the project itself, I am planning to write a paper and use Autocad to design the building. Is there anything else I can do to enhance the project? Thank you so much for your help.

So I was considering an idea that I may turn into a science project. So the push for sustainable urban development is not uncommon nowadays, and I was wondering about the feasibility of building a skyscraper completely off of the water and electricity grid. It would be self sustaining: greywater recycling, desalination, power generation by means of wind and solar energy, maybe nuclear. By having energy generation on site, the power loss is reduced since energy is not being transported a long distance. Having the building off the water grid may conserve water but also reduces stress on the water grid. I do not want to get too specific on here just quite yet, but I was wondering if its a good idea to a design a plan for the building as a science project. I'm in high school, so I am not looking to write a scientific paper here. Any suggestions/ideas welcome. Thanks! If I misplaced this post on the forum, sorry! I am new here.
