MRWA Submission - Sewer

Description

Instruction for setting up a project for a MRWA submission (Sewer).

Requirements

Xchange MRWA module

Project Attributes

Create a new project using the MRWA template for the authority you are submitting to, then add the following project attributes.

Project Attribute	Description
Municipality	Select from a list of municipality names prior to amalgamation.
File Management System	Type the File Management System identifier. Type a 10 character project reference number without special characters. The last six digits will be used to name the generated files.
Project Number	Type the project number. The text will be used in the header of the sewer asc file. This reference number can include special characters.
Stage Number	Type the stage number. The two digit number will be used to name the generated files.
Sewer Pipe Construction Date	Pick the date that the sewer pipe was constructed. This date will be used if a constructed date is not input for the pipe section.
Access Point Construction Date	Pick the date that the access chamber was constructed. This date will be used if a constructed date is not input for the access chamber.

Objects

The MRWA export uses objects on pre-defined layers to generate MRWA asc and dxf files.
Place objects on to the required layer and input the attributes predefined for the layer.

MRWA Object	Geometry	Layer	Notes
Sewer Pipe	Line or arc	Pipe-Sewer	Each pipe section (between access chambers) must be a separate line. The AutoCAD layer that the pipe is exported to in the dxf file is determined by the diameter of the sewer pipe and the line type. On export, the project attribute 'Sewer Pipe Construction Date' is used to create the 'Construction Date' attribute if it has not already been added for the pipe. A change in direction in the pipe indicates a horizontal bend. Snap change of grade points onto the pipe and then insert the points vertex into the line. The point must display the COG point symbol (See Change of Grade below.). You can run the 'Sewer Material Abbreviations' query to insert 'Material Abbreviation' and 'Packing Abbreviation' attributes based on the attribute values for 'Material' and 'Packing'.
Access Chamber	Point with the correct plan symbol for the type of access chamber.	Access Point	Access points must share a vertex with the end of the pipe. Run the 'Sewer Set Symbol' query provided with the MRWA template to automatically apply plan symbols for commonly used attributes and to view the symbol sizes that will display in the dxf file. The AutoCAD block name that is exported to the dxf file is determined by the size of the pipe and the points plan symbol. On export the project attribute 'Access Point Construction Date' is used to create the 'Construction Date' attribute if it has not already been added for the pipe.
Sewer Branch	Line	Branch	One end of the line must touch the sewer pipe. Use the modify Snap Vertex tool to place the start of the branch on the line representing the sewer. The height of the vertex at the end of the branch is the invert level. The branch is exported to the AutoCAD layer 49_4AA. On export the branch length is copied to the Branch Length attribute for the end of branch.
Spur Branch	Line	Branch	One end of the line must touch the branch leading to the sewer pipe. The branch is exported to the AutoCAD layer 54_216A.
End of Branch	Point with SEWPT plan symbol	Branch	The point must share a vertex with the end of branch. The branch plan symbol is exported as a block to the AutoCAD layer 49_4A. The Branch Length and Surface Level attributes are automatically created and populated when the project is first exported.
Surface Point	Point	Surface	The point must have the same easting and northing coordinates as the end of branch but not share a vertex. The height of the point is the natural surface level. The branch is exported to the AutoCAD layer 54_216A. On export the surface level is copied to the Surface Level attribute for the End of Branch.

Annotations

Annotation for objects are exported to the dxf file only.
Place text on the layer specified in the tables below, alternatively you can place all text directly on the required dxf layers as specified in the Melbourne Water Survey Manual.

Some annotations can be created automatically using a predefined text rule and just need to be moved and rotated to the correct location. Other annotations must be created manually on the specified layer using text styles, symbols or blocks.
Prior to annotating, run the following queries:

Sewer Set Symbol - Update the plan symbols for points based on the points 'Shape' or 'Type' attribute. Resize the symbols to the size they will display in the dxf file. This will help you place text.
Sewer Material Abbreviation - Automatically insert a value for the pipes 'Material Abbreviation' and 'Packing Abbreviation' attributes based on the value input for the 'Material' and 'Packing' attribute. The material abbreviation is used for flow text.

Flow

Line

Select lines on the Pipe-Sewer layer then use the text rule group 'Flow Text' or 'Flow Text Reverse' to create the material, size, joint packing and grade text.

Note:

For a multi-segmented line create separate grade text using the 'Flow Grade (Segment)' grade text style.
The AutoCAD layer that the flow text is exported to is determined by the diameter of the sewer pipe that the flow text is linked to and the text style used for the text.
The Flow Material text style uses the pipes 'Material Abbreviation' attribute. Ensure you have inserted the attribute value or run the query 'Sewer Material Abbreviations'.
The Flow Joint Packing style uses the pipes 'Packing Abbreviation' attribute. Ensure you have inserted the attribute value or run the query 'Sewer Material Abbreviations'.
The Flow Grade text style will display the appropriate decimal places for the computed grade value.

Notes

Annotations and objects not required for the generation of the asc data file can be placed directly on the AutoCAD layer.
The use of field codes to automatically place objects on the correct layer will assist you in this process.
Use layer groups to manage all layers related to a sewer submission.
MRWA blocks required for the sewer submissions are represented as symbols in the project and converted to blocks on export, with the following exceptions:
- Flow Arrows - Follow the instructions to create the flow arrow with the associated attribute values.
- Sewer Offset - This block is exploded on export
Default plan symbols and colours are specified for the layers.
Specify the AutoCAD prototype file 'MRWAPrototype.dxf' when you export to MRWA to ensure symbols are exported as blocks with the correct size.
Run the 'Sewer Set Symbol' query provided with the MRWA template prior to positioning annotation to automatically apply plan symbols for commonly used attributes and to view the symbol sizes that will display in the dxf file.
Run the 'Sewer Material Abbreviations' query provided with the MRWA template to automatically insert a value for the pipes material abbreviations attribute based on the value input for the material attribute. The material abbreviations are used for flow text.
Import property boundaries to create offset and tie text.
