Let’s look at what determines the cost of a bridge and possible ways to finance it. Would you need to get a small size loan from lenders like Monetti or look for other means of funding?

A Brief Overview 

You should budget a good amount of money for the construction of a basic bridge for personal use. A bridge intended for general pedestrian traffic may cost a lot. It will be about a quarter of a million if valued in dollars.

A larger bridge for a road might potentially cost tens of millions or more, depending on its size and construction materials. The type of materials used, the size of the bridge, and its design all have an impact on construction costs. If a wooden bridge is built at the back or front of your home, it will cost less than concrete and iron. 

So, the cost of building a bridge depends on a number of factors. We’ll discuss the costs associated with building various types of bridges as well as the variables that influence those prices. 

Pedestrian Overpass

In general, pedestrian bridges are designed primarily for foot traffic. Small bridges in parks to enormous boardwalks that can carry a large number of people and structures are all included in the category of pedestrian bridges. Due to the wide range of forms, sizes, and shapes, pedestrian bridge prices are highly variable. This type of bridge that can comfortably hold between 10 and 20 people at once should cost at the very least $250,000 if standard bridge construction materials are used. Viaconto personal loan might not be sufficient for this kind of project since it is designed for small businesses and personal use. A community contribution or grant is recommended for projects that cost this much.

Landscape expenses, labor charges, and permits all add to the cost. For example, land permits can cost a bit but not as much as the amount needed for construction.  

The Type of Material

Take note that the material of choice will greatly impact the bridge’s total cost. Concrete, steel, and wood are the most popular materials used for the construction of bridges. Typically, wood has the lowest initial cost of any material. A bridge made completely of wood will regrettably require ongoing repair. However, it’s economical to build and maintain. In fact, a loan from Vivus can cover the cost.

However, a bridge made from steel may not require repair or reconstruction for a longer period. Steel is sturdy and long-lasting but also heavy and prone to corrosion. A steel bridge may be more difficult to build depending on where it is located since it needs to be built using heavy machinery. Costs go up because it becomes logistically difficult for heavy vehicles to access paths that are farther away. 

Alternative Economical Material 

A bridge can also be constructed using aluminum. Aluminum is sturdy and resistant to corrosion. Although it is less heavy than steel, heavy machinery is still needed. The downside is cracking. After some years,  cracking is a potential risk with aluminum. Shiny aluminum is not often desired for a pedestrian bridge’s aesthetics. 

Another material is polymer reinforced by fiber. It is a strong, lightweight, and low-maintenance material for building the bridge. Although bridges made with this material may be costly, they are the least expensive in the long run because of their extended lifespan. A bridge constructed with polymer has a design life of 100 years before needing repair or replacement.

The Role of Size and Intended Use in Finance 

Construction cost is heavily influenced by the type of material chosen and the quantity required. Mandatory environment is equally important. An understanding of the environmental limits will determine things to be incorporated into the bridge design. You might need to perform a geotechnical analysis or a flood study of the area to fully comprehend what is needed.

Seas and Waters

Regardless of size, the expense of building the bridge over a body of water will affect the design. The cost of constructing a bridge is ultimately determined by the size of the bridge, the material chosen, safety considerations, labor needs, and other connected expenditures. Because they are typically built in space, bridges are highly expensive to build. It is necessary to create anything with better structural safety standards than something that is lying on solid ground with nothing but a structure or solid ground underneath it because it will be suspended over open air, water, and other risks. As a result, the building requires more materials, more engineering, and pricier construction methods.

ARUP has been able to provide structural engineering solutions to various bridge structures by using midas Civil as a structural analysis and design software. One example is the Stonecutters Bridge in Kowloon, Hongkong. The Stonecutters bridge is considered the world’s second longest spanning cable-stayed bridge with a main span of 1,080m. Due to its large span, the bridge was exposed to various dynamic forces including aerodynamic forces. Therefore, complex structural analysis was required for the bridge. In order to perform such analyses, midas Civil was used as a structural software in order to perform various analyses including Construction Stage analysis with time-dependent effects, cable tension optimization, and geometric nonlinear analysis.

ARUP not only provides state-of-the-art bridge engineering solutions to its clients but also aesthetic integrity to its bridge design. One award winning project by ARUP, the Helix Bridge in Singapore, clearly shows how ARUP is able to provide engineering solutions while saving the aesthetic integrity of a structure. The Helix Bridge design was inspired by the double-helix structure of a human DNA. However, at first, the design of the helix structure appeared to be structurally unstable and uncapable of carrying substantial loads. In order to tackle this problem, ARUP used its own engineering software to design a method that could make the Helix bridge structurally safe. In the end, ARUP was able to design a steel tubular truss bridge that kept the design of the helix structure of a human DNA. By doing so, ARUP was able to please all the companies involved in delivering this complicated project.

One of the most iconic bridge TYLI has been involved is the Weirton-Steubenville bridge in Ohio, USA. The Weirton-Steubenville bridge is an asymmetrical cable-stayed bridge with a single inverted Y-tower and I-shaped plate girders. TYLI provided engineering consultancy of the bridge by providing construction stage analysis and cable tension optimization of the bridge structure. Such complex analyses performed using the various features provided in midas Civil software. Furthermore, in addition to the 3D analysis of the bridge structure, detailed analysis for the anchor block was performed.

Jacobs is a company that strongly emphasizes the Industry 4.0 digital revolution and has been applying several new techniques to its projects. One interesting method is their newly implemented Jacobs Intelligent Operations Network (ion) that includes applications that tackle security and site safety, and also provides digitalized solutions for various architectural and engineering platforms. Furthermore, another method was the Intelligent Transport System that was applied to the Queensferry crossing bridge that includes an innovative technology that reduced traffic congestion in the bridge.

Jacobs has been able to provide various engineering solutions to various projects by using the different software MIDAS provides. Recently, Jacobs has been working on the West Gate Tunnel project in Melbourne Australia which include complex elements such as Tub girders. These tub girders have complex geometries but provide high torsional rigidity. Furthermore, tub girders are faster to erect and easier to inspect so engineers for this project decided to choose tub girders as their deck element. Various MIDAS Civil construction stage analysis functions were used to evaluate the different phases of tub girder construction. Furthermore, by using MIDAS Civil design modules, engineers were able to check key design factors, including moment, shear, buckling, and constructability.

HDR is also known for its world-renowned knowledge and expertise in bridge design and engineering. With more than 600 bridge specialists working on various complex and challenging bridges, HDR has provided innovative solutions to its various bridge projects around the world. Moreover, by using the latest technologies such as BIM, structural health monitoring systems, and accelerated bridge construction approach, HDR has been able to achieve its client’s goals.

One engineering technique HDR is very proud of is its advanced Accelerated Bridge Construction (ABC) technique. This technique is used for replacement of bridges that have been damaged or aged over time. HDR focuses on two very popular methods: The first ABC method includes transporting and replacing a bridge with a completely new structure. This method is carried out by building a completely new bridge on temporary piers next to the bridge that must be replaced. When the new bridge is completed, the old bridge is demolished and the new bridge is transported by modular transporters. The second ABC method HDR is famous for is its prefabrication of the replacement structure using modular parts. By doing so, the quality of the new structure will be met and construction time will be greatly reduced.
