What is the difference in cost of building a bridge vs a tunnel?

there's not going to be lot of difference. Both require an extreme amount of engineering depending on each situation. SO what guy up there said also applies. The biggest contributing factors for price are going to be\n1. Existing conditions \n2. Accessibility\n3. Design

Obviously this depends on the costs for your contractor in your area and labor.   Materials will vary in price as well. A good place to research that would be at a place such as Home Depot (for your materials)   Once you cost them out, you can shop for lower prices.   Permits also need to be costed in as well as cost for blue prints, septic systems or sewer; whether or not the lot has electric to the boundries or if you have to put in it; etc. Take your time and research it before you settle on a contractor.  There are so many ways to go; stick built, pre manufactured, kit (for log cabins) design simple or complex; single story or townhouse.  I did a lot of research on the internet and was never bored.  Learned a lot.  Have fun.

I hate too say, but that one is a tough to answer. To actually build them, probably around $50 but the rest depends on the spokes and hoops you get.

It depends they are between 50k and 120k.\n\nBut my uncle is a civil engineer he have his own business and he makes around 17 millions in a year.He have 12 engineers working for him.He have a master degree in structural engineering.I'm studying electrical engineering.GOOD LUCK!!!

The canal is more efficient, and actually makes monet now.\n\nThe economy has also grown, although there is much debate as to whether or not the loss of US bases has reduced this growth somewhat.

I would just focus on one or the other.  Civil engineering and architechure are actualy very diffrent.  Civil (structural) engineers design the structure of the building they use alot of math and physics to determine if a structure will be able to hold the loads placed upon it.  Architects on the other hand design the layout of the building.  \n\nI think your best option would be to earn a bachelors degree in what you are most interested in and then after you have a better feel of what you will do choose what field you want to get your masters degree in.  Who knows what you will want to do then.

Hello the costs range from anywhere between $134 per sq. feet to about $225 per sq. ft. for regular construction.  All higher end accessories and amenities will cost higher.

Think about the distances involved.  The supports for the tunnel would be impossible.  Also......even if it was possible....remember that once the tunnel is out of the atmosphere it would be bombarded by meterorites, space debris, etc.

Depends on the size of the factory, and what it's doing.  I'd have to imagine there would be a HUGE variance in cost among different factories.

West Point has a pretty amazing program for building bridges. You can find it by searching for west point bridge program.\nIts free, and fun!.\nIt helps you estimatr where the bridge will break, why it broke, what you should do to fix it, and how much your bridge will cost. It is very in-depth and I recomend it for anyone doing a bridge project.\nI hope this helps you.

From what I have found, the Mid Bay Bridge cost $81 million to complete. It took only 25 months to complete; 5 months ahead of schedule, and opened to traffic on June 26,1993. The bridge cost $44 per sq foot. It was selected as the top bridge project of 1993 by the FDOT(Florida Department of Transportation).

It'll cost more.  Fortunately, there are a lot of websites that let you calculate the difference.  Below is one site I found.  You put in your current salary, your starting city and destination city.  You get back what you'd need to earn to have the same spending power in the destination city.

I have an idea for you. Go to the site I provided for the source. It's a truss bridge with an arch. The best of both worlds. The most important thing is the arch. That is where all of the strength comes from in a bridge. I hope that helps.

I'd say the triangle; that is why most bridges are built with a "Triangle Truss." It makes the bridge more stable.

You might read about how the new Woodrow Wilson Draw Bridge was fabricated in a steel assembly plant before being shipped to Alexandria, VA for installation. It was the biggest drawbridge project of it's kind to date.\n\nhttp://www.wilsonbridge.com/

There definitely is no simple answer to this question, because a hydro electric power plant is not a small project. Like any big project, its costs would depend on the scale, the cost of materials, the design etc.

1a.  Since blasting is going to create instability in the surrounding material for a greater distance, digging will produce the more stable tunnel.  Assume you are depending upon the natural surroundings to support the shaft and not introducing artificial shoring.\n\n2a.  Technically since work is defined as the amount of force required to move a mass through a distance, both will be performing the same amount of work.  Benefit will be gained by the conveyor system which can essentially move material 100% of the time if it can be loaded continuously.  To achieved the same with cranes and trucks, there would have to be enough cranes so that a full load was constantly moving up the shaft.\n\n3.2.  Not sure what a "gigantil fisility" is let alone if one can be constructed of "concreat".  Also the debris being removed from the shaft may not be suitable component of "concreat".  Best option would be to sell it or give it away.  Probably some big holes around that could be filled in.\n\nConstructing a gigantic facility out of concrete might even be an option if you had enough Portland cement and the shaft debris was a suitable aggregate.
