N.B: It is very important to investigate the cost involved in construction. This influences whether or not you are awarded the tender and your overall design. The local authority will not award a tender to a very expensive contractor. So when choosing the type of bridge, keep in mind the cost factor. Research the cost of the bridge: Make a research on the different aspects of the bridge and write down the estimated realistic prices of each of the aspect to be used. a. Materials: Estimated total amount of the materials needed. b. Labour: Mention the labour force that you are going to need and the total amount of money you will need for labour.

When it comes to building bridges, materials can make or break your budget! Concrete, steel, and timber have different price tags, so it’s essential to check with suppliers for the latest costs. For instance, concrete might range from $100 to $150 per cubic yard, while structural steel can cost around $1,000 to $3,000 per ton. Don’t forget to include transport and delivery fees, as these can add surprising costs to your overall materials estimate! Now, let’s dive into labour—this part often gets overlooked but is crucial! You’ll need skilled workers like engineers, laborers, and project managers. Depending on your location, labor rates can vary significantly. For example, licensed contractors might charge anywhere from $30 to $100 per hour. Calculating how many hours each type of worker will need on-site for tasks like construction, supervision, and quality checks will give you a clearer picture of your total labor cost.
