PROJECT 2

AIM:

The aim of this project is to create,

• Alignments from the given Topo file
• Surface from the Triangles file
• Profiles for the alignment
• Pipe networks
• Corridor
• Plan Sheets
• Plan-Profile sheets
• Quantity take off
• Summary sheets

INTRODUCTION:

In this project, we are going to start creating surfaces from the given Triangles file and create Alignment from the Topo file. A profile for the alignment is then created. Further, we create assemblies for corridor modelling. A pipe network is also created for the alignment. Moning on, a quantity take off is performed. Finally, a sheet set manager containing the Key sheets, Plan sheets, Plan profile sheet and Summary sheet is created and published as PDF

Procedure:

• Open up the Triangles.dwg file

• Go to Drawing settings and check whether the drawing is in appropriate coordinate system

• Create a surface named EG(Proj2)

• Under surface EG(Proj2), Drawing objects – Add

• Window select the objects

• Delete the unwanted lines in the surface to get a perfect surface

• Export the surface to LandXML file

• Create a new file with template Company XYZ- Survey template

• Save it as ‘ GDTMRD01.dwg’

• Set working folder as Proj2- DS1

• Associate project with the current drawing and create data shortcuts of the surface so that it can be used any time

• Open up a new drawing with Company XYZ template and save it as ALGNRD01.dwg

• Then Associate Project to the current drawing

• Bring in the surface

• Follow TOPORD01.dwg for creating alignment file
• Now go to Alignment – Alignment creation tools

• Draw fixed tangent lines and connect them using appropriate free curves

• The road is a 24’ proposed width road. So it is 12’ on both sides from the centreline of the road
• Click on offset alignment and enter the incremental offset on the left and right as 12’. Also change the alignment style if required

• Add Data Shortcuts of the Alignment

• Create a new geometry file by name DSGNRD01.dwg

• Create reference of the alignment

• Use fillet command at the beginning and end of the road

• Take offset of 40’ on either sides for the riderway line

• Refer to the project scope for turnouts and draw polylines extending from the riderway where turnouts are given

• Break the 12’ offset line. Fillet the PL and 12’ offset line

• Join the polylines and make it a single object for hatching

• Using hatch command click on select to select the boundary

• Create a new sheet set from a example sheet set

• Create a sheet set by name ‘Proj2_Sheetset’ from the example sheet set

• Create a new template file from the COMPANY-XYZ.dwtfile and name it as ‘Plan Sheets.dwt’
• Open any previous dwg files and open the design centre by pressing Ctrl + 2. Bring in the Company Sheet 50 Scale layout
• Adjust the Page Set up to 11 * 17 and rename it as ‘ Single Plan 50 Scale’
• Create a single viewport and change its type as ‘Plan’, order as ‘1’

• Create a new layout called Dual Plan 50 Scale with 2 viewports in it

• Create a new file with template Company.dwt and rename it to CLIPRD01.dwg
• Create reference of the Proj 2 Alignment.

• Right click View Frames and select Create View Frames

• Create Data Shortcuts of the View Frame

• Open a new dwg by name PLANRD01. Dwg with the template Company XYZ .dwt

• Bring in the alignment and view frames

• Add to the existing sheet set
• Rename and renumber the sheets

• To add additional sheets to the current sheet set. Open KEYSRD01.dwg and select all layouts. Import Layout as Sheets

• Arrange in order. Rename and Renumber

• Add Alignment Labels

• In the Superelevation calcs.xlsx , enter the radius, PC, PT of the curves and Superelevation rates by seeing the label

• Now enter the similar way for the remaining curves
• Ensure that the zero cross slope station in (Level crown) for curve 2 has to greater than or equal to the zero cross slope station out for curve 1 to get enough tangent for curve transition. If its lesser, pull the curve up or down to get sufficient tangent distance for smooth transition
• Now lets check the same for curves 1 and 2

• Now we can infer that we have a smooth transition to curve 2 from curve 1
• Select the alignment , go to Superelevation and select calculate/edit superelevation
• Edit the values in the superelevation calculator from the excel sheet

• Go to Profile – Create Surface Profile for creating profile for the alignment

• Click on Draw in Profile View

• The profile view grids can also be frozen by using Layer Freeze
• Go to Line command-Transparent-Station Elevation

• From the excel sheet, check where the normal crown ends/ the curve begins and draw a line in that particular station

• Go to curve- free vertical curve (parabola)
• Now draw the parabola by selecting 2 entities and giving a minimum K value
  • For crest curve, K = 61
  • For sag curve, K = 80

• Now create a new file called ‘MODLRD01.DWG’

• Bring in the surface EG(proj2)

• Also bring in the alignment and profile

• Select a appropriate layer and draw a rectangle for assemblies
• Now place a piece of text ‘Assemblies’ by using MText command

• Go to Home- Assembly- Create Assembly

• To bring in the name of the Assembly ,use MText command ,right click – Insert field-Objects

• To start creating sub assemblies,
  • Click on the sub assembly Lane Superelevation AOR and go to Properties

• Make the following changes in the properties

• Add shoulder to the lanes by using subassembly ‘ Link Width and Slope’

• Now add the Target Not Found subassembly by using Conditionals- Conditional Horizontal Target

• Then add Conditional Cut or Fill Subassembly

• Repeat the same for Fill also

• Use subassembly Generic - Link Slope to Surface-Properties

• For the fill side, Daylight first and then create Ditch

• Mirror the subassemblies for the left lane

• For creating corridors, go to Home-Corridor-Corridor

• Select the object and right click-Object Viewer

• Create alignment on the drive way side. To create intersections, connected alignment has to be created at first

• Select the first and second alignment to be connected and select a location to place the alignment
• Then create surface profile for the alignment DRIVEWAY1

• Build the corridor for the driveway
• Copy the sub assembly created and paste it below
• Name the subassembly as Drive
• Delete everything except daylight

• Repeat the same for other Driveway too

• Open up the PDPLRD01.dwg
• Bring in the Proj 2 alignment by creating reference
• Draw a pond using line command and arc command
• Join all the segments

• Go to Prospector- Points- Create Points
• Add points along the pond and add elevation as 148
• Go to surface POND- Definition – Point Groups – All Points

• Create a surface for corridor by just right clicking and corridor properties- Surfaces

• Create data shortcuts of the corridor and corridor surface created

• Now create a new file called ‘DRPRD01.dwg’ with reference of the template ‘ Company XYZ.dwt’
• In the DRPRD01.dwg, check the pipes and structures. Add new part size if needed. This could be opened from Settings- Pipe Networks- Parts List-Storm Sewer-Edit

• Home – Pipe Network- Pipe network creation tools

• Start creating Pipe Network

• You can also Add Labels from the Annotate- Add Labels- Pipe Network

• For creating the alignment and profile from the Network part, Home- Alignment-Create Alignment from Network part

• Create the grading group and pond surface in a pond file.
  Under prospector tab, Sites – New, enter the name as POND
• Under the POND sites- Grading group – New

• Inorder to create feature lines, go to Home – Feature lines-Create Feature lines

• To create the grading, Home – Grading – Grading creation tools

• Open Plan Profile Sheets .dwt and in the dual plan 50 scale change the properties as Plan and Profile respectively

• Create a new file called PLPRRD01.dwg
• Bring in the surfaces, alignments,driveways, pipe networks

• XRef the DSGNRD01.dwg file

• Create view frames for plan profile view

• Start creating sheets

• Create a RDXSRD01.dwg and bring in the alignments, surfaces and pipe networks

• To create sample lines,

• Open the SECTION.dwt file given in C11 assignment folder and use it as template for creating cross section sheets

• To create sheets for cross sections, go to Output-Create Section Sheets

• Rename and renumber accordingly

• Create a QTDSRD01.dwg and bring in the alignments,surfaces and pipe networks
• Analyze- QTO manager- Open Pay item – Florida. Browse to the .xml files under Agency folder
• Assign various pay items

The following pay items are needed:

1. Clearing and grubbing
2. Stabilization zone
3. OBG
4. Turnouts
5. Desilting pipe
6. Concrete driveways
7. Pavement
8. SOD
9. Guardrails

• For calculating volumes, bring in the top and sub base surfaces from MODLRD01.dwg to QTDSRD01.dwg

• Open ‘ Summary of Earthwork’ excel sheet
• Enter the cut ( excavation) and fill (embankment) values. If the subsoil is not suitable for construction, it has to be excavated and filled in with a proper material. So 15% is added for excavation and same amount to be used for embankment
• Add pay items to pipe network also
• Once all the payitems are assigned, it is now time to perform the takeoff
• Analyze -> Takeoff
• Select Detailed and click on Compute
• Save the Detailed Area, Count and Linear . xsl files

• Now go to File explorer and change the file extensions to .csv
• Observe that the Area quantities are without any precision/decimals
• So go to Toolspace -> Settings -> Quantity Takeoff->right click -> Edit Feature settings
• Now go to Area and change the precision as 3
• Fill in the summary excel sheets by referring to Detailed Area, Count and Volume
• Perform Summary take off from QTO

• Fill in the Summary Quantity excel sheet
• Also arrive at the Project estimate and prepare the Bid form

• Press Ctrl + 4 and open the Sheet set manager
• Import Layout as Sheet and update the existing sheet set

• Right click on the sheet set and select Publish- Publish dialog box to create PDF
