With lots you can group assemblies for transporting to site. Lotting means that you evaluate specific model parts with respect to the number of units that can be carried by a transfer vehicle.
For example, you can calculate how many concrete truck deliveries are needed to pour the footings or slabs for a specific portion of the model. With this information, it is easier to determine area requirements and create an erection schedule.
When you define lots, you must take into account the load-carrying capacity of the vehicle, because a lot cannot exceed the maximum total load capacity. You can calculate truck load sizes based on material weights and model quantities. For most model parts, the weight is based on the size, length, and material of the part.
To view the properties of a part, double-click the part, or click Inquire object and select the part.
You can use lotting in conjunction with the Sequencer tool. For example, you can load each part of the model onto a specific truck based on the erection sequence of the part.
The basic lotting process is the same for steel and concrete parts. However, if you are using cast-in-place concrete, remember that the concrete is transported in a volumetric container (for example, in a ten-cubic-yard truck). In that case, you must calculate the weight-carrying capacity of the concrete vehicle before defining the number of lots.
