Add or Modify a Roadway Maintenance and Rehabilitation Schedule Record

This dialog is launched when the "Edit Record" button is clicked for a "Rehabilitation Schedule" record in the Add/Modify Roadway Assembly dialog.

This form allows users to easily add, modify and navigate through the list of "Rehabilitation Schedule" records.

Note:
Each "Rehabilitation Activity Type" parent record must have a unique combination of "Year After Initial Completion" and "Activity Type". Failure to ensure this unique pairing will cause record navigation to always go to the first of the pairs in the list.

Activity Timing:

Year After Initial Construction:: Enter the number of years after the initial construction that the activity is scheduled.
Sequence:: This is the sequential order in which the activities are scheduled and is not generated automatically, the user must enter it manually. It is only used for sorting purposes.
Expected Lifespan:: Enter the expected lifespan, in years, that the activity is scheduled to last before replacement or repair. This is used to prorate the effects of any activities whose expected lifespans extend beyond the overall project lifespan.

Activity Details:

Activity Type:: Choose the Activity Type, this will determine which equipment is used for the activity and specify the list of choices available in the Specific Activity column.
Specific Activity:: Choose the specific activity in the maintenance and rehabilitation schedule.
Description:: Enter a user defined description or name for the activity.
Total Cost:: The user can enter the total projected or current (not Net Present Value) cost for the current rehabilitation activity. It is the intent that these costs will be exported to an LCC tool where discount rates etc. will be applied.

Affected Road Element:

Paved Shoulders:: Choose this if the activity is to be applied to the paved shoulders. This and Lanes are mutually exclusive, if one is selected, the other will be unselected.
Lanes:: Choose this if the activity is to be applied to the lanes. This and Paved Shoulders are mutually exclusive, if one is selected, the other will be unselected.

% of Road Element Affected by Activity:

% Surface Area:: The percentage of the roadway's surface area that is to be affected by the activity. This and % Length are mutually exclusive, if one is selected, the other will be unselected.
% Length:: The percentage of the roadway's length that is to be affected by the activity. This and % Surface Area are mutually exclusive, if one is selected, the other will be unselected.
Quantity:: A value, calculated automatically, depending on the the roadway design, and whether the paved shoulders or lanes is chosen, and the percentage of either surface area or length. You cannot edit this value.
Unit:: The unit of measure for the activity depending on whether you have entered a percentage of surface area (m2) or length (m).

Material:

Material is Removed:: Choose if the activity involves the removal of material from the job site (i.e., to a reclammation stockpile location). This and "Material is Added" are mutually exclusive, if one is selected, the other will be unselected.
Material is Added:: Choose if the activity involves the addition of material that is transported to the job site. This and "Material is Removed" are mutually exclusive, if one is selected, the other will be unselected.
Material Type:: Choose Material Type to specify the list of choices in the Material column.
Material:: Choose the material type for the current activity in this column.
Thickness:: Enter the thickness of the current activity (removal or addtion of material), in millimeters, in this column.
Width:: The width is automatically calculated according the the roadway design and the % Surface Area or % Length value. If % Length is chosen (e.g. for a Crack Rout and Seal activity), the width calculated will be a default width for the routing operation. You can edit the width if you want, and this is the value that will be used to calculate the volume of material used for each activity.
Quantity:: The quantity is calculated automatically according to the roadway design, thickness and width values, and is not editable by the user
Unit:: The quantity unit is determined automatically and is not editable by the user.
Mass:: This column shows the mass, in tonnes, of the material chosen for the current element and is not editable by the user.

Buttons:

Help Button:: Click the "Help" button to open the Help pop-up window.
OK Button: Click the "OK" button to accept and save the current Rehabilitation Schedule record and close this dialog.
