ITEM TYPES OVERVIEW

An Item Type is a user defined set of properties used to describe graphical and non-graphical information of an object or element. Item Types are set up and managed by the CTDOT CAD administrators as part of the delivered workspace. Item Types will be attached after placement for elements such as lines and shapes. The workspace has been set up for certain Cells to have Item Types attached upon placement. The properties of an Item Type can be edited by the user in the Properties dialog box along with the other properties of an element. The properties in Item Types can be used to label and report.

CTDOT Item Types are connected to the Department’s Master Bid List that contains pay item numbers, descriptions and units. Users will enter the required pay item description and the item number and pay unit fields will auto-populate. The most up to date Master Bid Item Lists can be found on the Department’s Contract Development Website.

In the image below notice the look up information is grayed out and the user input is not. The greyed-out properties are getting auto-populated by other Item Type property fields or other attributes on the file itself. Some user input fields are actually pick lists and others are strictly manual input.

 HIGHWAY TAB ITEM TOOLS
» PLACEMENT

The Highway tab on the CTDOT workflow will be used to place 2D Linear Elements, Shapes and Cells.  

  

The tools in the Linear and Area pull down menus do not automatically attach Item Types like the Roadway Safety End Treatment Cells. Item Types will be attached after placement by using the Properties toolbox or the Attach Item Tool. Templates have been created for common pay items and can be selected under the General >Template property by browsing to Roadway\PAY ITEMS\...and selecting as needed.

As described above in the Item Types Overview. Users will enter the required pay item description and the bid item number, and the pay unit fields will auto-populate. The Quantity property will pick up the Linear, Count (each), Area, or Volume measurements.

» ITEM TYPE LIBRARIES

Item Types are used for two main purposes, to assign Pay Items and to assign Asset Information to Cells, Shapes and Lines.

Pay Items

The Roadway Pay Items Item Type Library will be used to assign Pay Items.

Item Type:

  • PAY ITEM - HW: Used to assign one pay item to a graphical element

 Roadway Pay Item Properties

 

Pay Item Properties:

  • Item_Description - uses a pull-down menu. By selecting the down arrow in the Property Definition and entering part of an Item Description, a selection pick list will appear. Note: you can enter any word in the description, and it will filter regardless of the order. 
  • Item_Number - uses a look up table and will update based on the selected Item_Description.
  • Unit - uses a look up table and will update based on the selected Item_Description.
  • Volume_cf - will populate if an Item_Description using a volume unit type is active (c.f., c.y., gal, lb., or ton).
  • Material_Density_pcf - the user will need to manually enter the Density in Pounds Per Cubic Foot to calculate lbs and tons.
  • Quantity - uses the following equations with the option of adding a manual amount if necessary.
    • l.f. = LinearElement_Length
    • v.f. = Manually Added Quantity
    • ea.= 1
    • s.f. = EnclosedArea
    • s.y.= EnclosedArea / 9
    • acre= EnclosedArea / 43560
    • c.f. = Volume
    • c.y.= (Volume / 27)
    • gal = (Volume * 7.48051948)
    • lb. = (Volume * Material Density pcf)
    • ton = (Volume * Material Density pcf) / 2000
  • Complete_Quantity_Override - if set to Yes, the desired quantity will only use the Manually_Added_Quantity field and will disregard the graphical look up. If set to No the desired additional Manually_Added_Quantity will be added to the graphical look up. 
  • Manually_Added_Quantity - if no additional quantity is required leave this set to 0, any value added here will be added to the graphical look up in the Quantity field.
  • Notes - Type in as needed.

Asset Information

The following CTDOT assets will be tracked moving forward so all Property fields in the Item Types below should be fully populated and filled out for each item placed in a project.

» REPORT DEFINITIONS

Report Definitions are available through the Reports dialog box. A Report Definition for these 2D roadway items has been defined and can be used to create quantity reports. This Report Definition is a way to extract and present data from a DGN file in tabular format. Reports can be placed as a table as well as exported to Excel workbook or .csv files. A predefined report has been created for use under Roadway called Pay Items.
