Why Dumpster Dimensions Matter When Selecting a Rental

When planning out a construction job, waste disposal can often be treated as an afterthought. We believe it’s important to reverse that approach by focusing on the waste needs of a project at the early stages of project planning.

Otherwise, waiting until the last minute to decide how to dispose of bulky waste can create a host of problems, including safety issues, wasted time, and compliance concerns. These problems can be avoided altogether with some extra planning, including renting roll-off dumpsters for the job site.

To maximize your dumpster rental, it’s important to know the dumpster dimensions of the dumpsters you need for the site. Taking this step will ensure that all of the waste fits in the dumpster space, preventing additional work trying to clean up the waste overflow.

Let’s take a closer look at the different commercial dumpsters available for rent so that you can select the most suitable units for your next project.

Dumpster Dimensions: Why Does Size Matter?

There’s nothing worse than being on track to complete a project and then finding out you don’t have the appropriate resources to manage all of the waste generated at the job site.

Maintaining visibility into the amount of waste accumulated at the job site can help you plan projects that run smoothly from start to finish.

Knowing how much waste each type of dumpster can hold will help you plan for (a) the right-size dumpster and (b) the appropriate number of dumpsters for the job. Finding the sweet spot will help you save time and money.

There is another key consideration when making a rental determination: the availability of space at the job site.

Placement Limitations

Spatial limitations are a crucial factor to consider before selecting your roll-off dumpster. This is another reason why we recommend incorporating waste plans into the early stages of a construction project so that you know where you can physically place dumpsters at the job site to manage waste.

Making waste plans an afterthought could limit your ability to rent the full number of dumpsters you need for the job. Or, trying to cram dumpsters into tight spaces could interfere with the work being completed, creating safety hazards.

Fortunately, all of this can be avoided with a bit of consideration before the project begins. Let’s take a deep dive into the dimensions of roll-off dumpsters from Gainsborough Waste that you need for the job.
