For construction debris and waste, typical dumpster sizes are 10 cubic yard, 15CY, 20CY, 30CY, and 40CY. These ‘Roll-Off’ dumpsters are delivered off the back of a large truck and are made of aluminum or steel. One would be well advised not to unload a dumpster on grass or asphalt pavement as dumpsters are quite large and heavy, and will damage most surfaces as they are loaded and unloaded off the truck.
Dumpster rental companies typically charge the contractor by the ‘Pull’ which is when it removes the dumpster from the construction site. Dumpster use on a construction site is often a contentious issue. Often times the General Contractor is required by the owner to provide dumpsters for the project, but has also passed dumpster usage requirements on to its subcontractors. Dumpsters fill up very quickly, and sometimes by one trade depending on the type of work occurring at the time. This can aggravate other trades who go to use the dumpster and find it full.
There are commonly tonnage charges associated with certain types of construction waste and demolished material. Demolished concrete and asphalt for example are typically only loaded a portion of the way up the dumpster fill line as on-road and axle weight limits should not be exceeded. Also tonnage overage charges can add up considerably, not to mention overfilling can sometimes lead to the dumpster rental company being unable to load the dumpster and take it away, which typically leads to a timely and costly situation to fix.
