Dumpster Considerations For Large Construction Jobs
You have a lot of information that needs to be considered for a roll off dumpster rental when you have a large construction or a large demolition project. You need to know what types of materials, the volume of debris, the project’s duration, the availability of dumpsters and more. Proper planning in advance can reduce the price of a roll off dumpster rental service by up to 20% or more on large projects.
Compare Apples to Apples
Sometimes you can save quite a bit of money on a dumpster rental when you compare two different companies with two different size dumpsters. For example, you have a large restaurant demolition job and one rental company can supply you with 3 dumpsters that hold 40 yards each. They will be swapped out when they are full and the total cost is $1,500. Another dumpster rental company can only supply you with 20 yard dumpsters. From this company you would need 6 to hold the same volume as the first company. If 6 dumpsters cost $300 each then your cost is $1,800. In this example, if you go with the first dumpster rental company you have a savings of 20% on your rental price.
Get The Biggest Dumpster Possible
The prices for dumpster rentals do not increase in the same amount for each size larger. For example, if a 10 yard dumpster rents for $304 and a 40 yard dumpster rents for $488, the price does not go up incrementally with the size. The 40 yard dumpster isn’t four times as much as the 10 yard dumpster in price. This fact makes it more cost effective to rent the larger dumpster that is available to you for a large construction or demolition job. You may be able to rent one larger dumpster to save you from renting a second or third one and you can save several hundred dollars in doing it in this manner.
How to Estimate the Amount of Debris
If you are wondering how to estimate the amount of debris on a demolition project, you can figure this out with a formula that is used by FEMA. To find the cubic yards of debris on a building you multiply the length times the width times the height times 0.33/27or L x W x H x 0.33 /27= cubic yards of debris. For a home, you multiply the length times the width times the number of stories times 0.20 times the vegetative cover multiplier to get the cubic yards of debris. The vegetative cover multiplier is yard waste. The formula for a house demolition is expressed as L x W x S x 0.20 x VCM = cubic yards of debris.
Another rule of thumb to estimate your amount of debris is that one ton of construction and demolition debris equals approximately 2 cubic yards.
Once you have this estimate, it makes it much easier to determine what size of roll off dumpster you will need for a specific job. Some dumpster rental companies offer 40 and 50 yard containers for large jobs. If you are making clean loads of only one type of debris that is heavy, such a shingles or concrete, then you may not need a 40 yard dumpster. Some rental companies require you to use smaller containers for heavy materials.
Key Items to Consider When Renting a Roll Off Dumpster
The proper planning can help you to come up with a strategy for dumpster rentals so you can maintain a smooth workflow at your construction site. Sound debris removal strategy is very beneficial in other ways to you and not only in the total price.
You can improve worksite efficiency with a good schedule. When you plan your schedule, consider your dumpster delivery, pickups and swap outs so that you reduce or eliminate delays on the job. Be clear with the dumpster rental company as to your disposal needs and schedule and if they can’t meet your needs, then you should shop around for another rental company.
When you have a dumpster on site and you can dispose of the debris immediately instead of piling it up, you can maintain a much safer work environment for everyone. According to OSHA, the fatal injury rate in the construction industry is higher than the national average of all occupations. So as a contractor, you need to make maintaining a safe and clean job site a top priority.
You need to estimate the number of total dumpsters that you need to complete your large construction or demolition job. You should also plan on either container swap outs or live loading is a part of your debris removal plan. Make sure you verify all the details with the dumpster rental company before you book with them. You need to make sure they can accommodate live loading if that is something you need and make sure they have the equipment to deliver multiple dumpsters all at once or during the day as you need them.
Planning in advance for dumpster rentals on large jobs can save you a lot of headaches. Knowing the amount of debris, its weight and how you plan for it to be disposed of in advance will help you to have a smooth operating construction site that is safe for all of the employees.
