If you are a civil or mechanical engineer, you are likely to be part of a bridge engineering project at some point in your career. It could be a modest project, where you are engaged to design a simple footbridge over a busy highway. Or could be a major project, where you are engaged as part of the team designing a huge bridge across a sea/ocean creek. Either way, you are likely to find the task of designing and building a bridge challenging, yet exciting at the same time. You know that you have to get everything right, if the bridge is to be safe and durable. And that is where you are likely to find yourself considering factors like:
- The load to be borne by the bridge
- The size of gap to be bridged
- The terrain where the bridge is to be set up.
- The (typical) weather conditions at the bridge location.
- The funds available for construction of the bridge.
The later consideration, on availability of funds, deserves special comment. For it is the main determinant of the type of bridge you can afford to design. Let’s take, for instance, an assignment where you are required to build a bridge over a sea creek. You may desire a conventional bridge, that connects smoothly with the road on both sides of the creek. But if the funding available is too limited, you could find yourself having to do a suspended bridge – which is functional, but lacks the smooth connection to the road on both sides of the creek that you’d otherwise have wanted. Remember, financing is usually a key challenge in these sorts of projects. Oftentimes, the financing for engineering projects comes from people’s taxes. Yet people can’t afford to pay too much tax. You always have to keep the average worker, and the state of his finances in mind, while working out how much to tax. Take, for instance, a person working at the US Postal Service. That means he gets his paychecks by visiting the lite blue usps employee login page, and signing in there. Yet you can also be assured that this sort of person is likely to complain bitterly, and feel demoralized, if he logs into the portal at www.liteblue.USPS.gov, only to find that he has been taxed too much. So there are limits to taxation. And this in turn means that public finances for engineering projects are limited. For you as an engineer, it means that you are likely to face constraints in implementing your plans. You therefore will often have to compromise on some things – as long as the safety isn’t affected.
