You may have already guessed that the standard answer is: “It depends.” That’s because there are so many factors and variables involved in the process, making it challenging to forecast an accurate timeline.
For example, pedestrian bridges come in at least four different types: arch, beam, suspension, and truss. Plus, there are various materials and features that determine the bridge’s overall cost and the amount of time it will take to complete the project.
Breaking down the project into its typical stages makes it possible to develop a timeline that provides a general idea of how long it will take (but keep in mind that your time of completion could differ):
Stage 1: The Design and Planning Process
Pedestrian bridges allow people to cross over a space or a body of water. Designing and planning are critical to the success and safety of the project, so it’s best not to rush through it. As you meet with the bridge construction company, here are some of the initial considerations that should be discussed:
- Decide how wide the bridge must be – who will use the bridge? Walkers, runners, cyclists, ATVs? Maybe 4 feet is sufficient, but you might decide that 8 feet is more appropriate.
- Determine the site conditions: Is the terrain flat, or are there elevation changes?
- Get a geotechnical report: A geotechnical analysis will help to determine if you need deep foundations. Knowing the surrounding soil conditions makes it easier to design the footing.
- Develop an abutment plan: The abutment plan can be as simple as transitioning from the ground to the bridge. However, if the bridge is crossing water, deeper foundations might be needed.
Allow 6 to 8 weeks for this first step.
Stage 2: Order the Bridge and Wait for Design Drawings
After ordering your pedestrian bridge, you should receive a set of drawings.
Allow 2 to 4 weeks for the design team to create these drawings.
Stage 3: Review and Approve the Drawings
After you review the drawings, you will need to obtain permits. The permitting process could involve coordinating with several agencies with permits from each of them.
Allow another 2 to 4 weeks, depending on the number of agencies involved.
Stage 4: The Contractor Installs the Abutments while the Company Manufactures the Bridge
Allow 8 to 14 weeks for this part of the project, although more complex bridges could take longer.
Stage 5: The Contractor Delivers the Bridge and Completes the Installation
The last step involves unloading the truck, bolting any splices, and setting the bridge in place. Smaller bridges could take as little as a day or two, while complex structures could take several days.
Allow 2 to 4 days to complete the final step.
