Lotting

Lotting

With lots you can group assemblies for transporting to site. Lottingprocess of creating lots and adding assemblies to them

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.

Tip:

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 concretecast unit type where the concrete is formed, poured, and cured in its final position

, 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.

Create a lot

Create lots to group assemblies for transporting to a site.

  1. On the Manage tab, click Lotting.
  2. Click Properties... to display the Lot Properties dialog box.
  3. Enter a name in the box at the bottom of the dialog box.
  4. Enter a lot numbernumerical value that indicates a lot

    in the Number box.
  5. Enter the maximum weight of the lot in the Max weight box. The units depend on the settings in File menu > Settings > Options > Units and decimals .
  6. Click Add.

    Tekla Structures creates an empty lot with the defined properties.

Add parts to a lot

After you have created the needed lots, you must select each part of the model and assign them to a lot until the total load weight of the lot reaches the specified target.

  1. On the Manage tab, click Lotting.
  2. Select an existing lot from the list.

    Tekla Structures highlights the parts included in the lot. The total weight of the lot and the number of assemblies it contains are displayed under Applied values.

  3. Hold down Shift and select the parts that you want to add to the lot.
  4. Click Apply selected.

    The weight and the number of added parts are displayed under Current values. Tekla Structures displays a warning message if the weight limit of the lot is exceeded.

  5. Click OK to close the dialog box.

    When you re-open the dialog box, the Applied values include the weight and the number of parts you added.

Warning:

Parts can belong only to one lot at a time. If you add parts that are already in an another lot, the parts will be removed from that lot.

Remove parts from a lot

  1. On the Manage tab, click Lotting.
  2. Select an existing lot from the list.

    Tekla Structures highlights the parts included in the lot.

  3. Hold down Ctrl and select the parts that you want to remove from the lot.

    If you want to remove all the parts from the lot, click somewhere in the model without holding down Ctrl.

    Tekla Structures deselects the parts.

  4. Click Apply selected.
  5. Click OK to close the dialog box.

Delete a lot

  1. On the Manage tab, click Lotting.
  2. Click Properties....
  3. Select an existing lot from the list.
  4. Click Delete.
