Pedestrian bridges certainly aren’t one-size-fits-all. No two sites are the same, budgets and upkeep requirements differ, and aesthetic preferences play a big role too. But what about actual construction? As we’ve said before, there’s more than one way to build a pedestrian bridge. That’s why we offer multiple options for building your bridge.
Does the DIY construction approach appeal to you or your organization? Whether you are looking for a challenge, want to economize wherever possible, or a little of both, Axcess can help. Here, we’ll address some common questions DIY bridge builders have.
1. Can I Really Do it Myself?
For bridges with spans of about 40 feet or less, it’s definitely possible to do installation yourself. And, of course, it helps if you have an internal crew of employees and/or willing volunteers and at least some experience with tools and construction.
For a span length between about 40 to 60 feet, it helps to have some assistance from one of our experienced field reps. And spans over 60 feet are usually best left to a professional contractor.
Axcess has options for each of these:
- Design only, with a customized bridge design that’s easiest for a novice to install themselves
- Design and assist, which includes design work plus a qualified field rep to guide your crew
- Design and build, which is a turnkey package including design, assembly, and installation by the Axcess team
2. Why Does the Span Matter?
Generally speaking, the longer the distance a bridge spans, the greater the loads become, and the heavier and more complex the supporting members and components get. And as the design becomes more complex, even preassembled bridges will have larger pieces to unload and maneuver, require more work to connect sections, and generally be more challenging to install.
Bridges that accommodate smaller spans, such as beam bridges or culverts, are generally easier for the DIY installer or a first-timer. Truss and suspension (or cable-stayed bridges) are examples of complex bridge structures that are often used for longer spans, and are more unwieldy to install easily, especially if you don’t specialize in this type of construction.
3. Are My Options Limited if I Install it Myself?
Some types of bridges are easier than others for non-experts to work with successfully – after all, you want to avoid getting part way through construction only to realize you’re in over your head. That’s why an important bridge design consideration is selecting the bridge type and materials that are geared toward novice or non-expert installers. Beam bridges, culverts, and boardwalks are all good candidates for DIY construction and installation.
But just because the design is relatively easy to install doesn’t mean it is lacking in functionality and visual appeal! We always take the time to understand your priorities for the project, including aesthetics and ongoing maintenance (or lack thereof), so your finished bridge meets expectations and requirements.
4. Do Site Conditions Have an Impact?
We do an evaluation first to assess any concerns about flooding, erosion, soil conditions, or other siting matters like existing trees/vegetation, adequate access, etc. We can often provide suggestions for accommodating these; however, if conditions are truly prohibitive or complex, it may be more appropriate to have the work done by a contractor.
5. What Equipment Do I Need?
We do our best to create designs and prefabricated pedestrian bridge components that can be hand-carried or put in place with minimal heavy equipment. Some items that will be helpful for bridge installation include:
- Bobcat or small excavator for moving earth and construction materials.
- Wheelbarrow or mini mixer for preparing concrete for abutments
- Hand tools like shovels, drills, and trowels
Much of the specialized equipment needed is small and can be rented if you don’t have it on hand already. And because the components are quick to install, rental periods are usually short.
Our pre-assembled, modular bridge designs are also advantageous because there is some equipment you probably will not need. This includes a backhoe, loader, and other large earthmoving equipment, cranes, powered post-hole diggers, and large quantities of lumber and tools for building framing for complicated poured concrete components.
6. How Long is it Going to Take?
Installation time depends on a few things: your experience level, any site prep (e.g. clearing vegetation), the size of the bridge, and material choice. For example, while a smaller bridge can be installed quickly, the project may take longer if there are fallen timbers or rocks to clear, or an existing structure to demolish and remove. As a rule of thumb, we suggest planning a full week of construction from start to finish.
It’s also possible to run into unexpected construction challenges despite having the best design. We offer the experienced field rep option to help navigate these challenges while still allowing you to gain the experience and skills by doing the majority of the work with your internal crew.
7. What Happens if We Change our Minds?
We understand that sometimes changes happen. The final goal is always a beautiful and functional bridge, and we promise to help you reach it. So, if at some point in the project you determine that the DIY route is not for you after all, simply get in touch with us. Keep in mind the original timeframe for your bridge project because it may need to be extended in order for us to schedule a crew. Pricing will also be affected.
No matter what route you choose for your pedestrian bridge project, when you work with Axcess, you can count on a well-planned design and expert guidance that is informed by our construction experience. Please contact us to learn more!
