Public Works
PROJECT: Creation of “Base sheets” With All Existing Topographical Features (Natural & Man-Made) And Utilities.

Scope of Work: This project needs the creation of “base sheets”. Essentially a base sheet is a P&P sheet with all existing topographical features (natural & man-made) and utilities shown in both plan & profile views. The topography at the project site has been mostly raw land and there were few existing underground utilities or above ground entities that constrained design.

The Client send comprehensive survey data of the project area (often in an urban environment) and we exhibit the given survey data on plan sets.

Given below is a brief overview of the project:

  • The Client sends to us an ASCII file that should be rendered to a DWG file format using LDD. The points in the DWG file format are coded (“FV” for fire valve, “TC” for top of curb, “GL” for gutter line, “DW” for drive way, etc.)
  • WE creates a plan view “picture” of what the actual conditions look like on the ground by connecting the points in LDD and creating a map which also shows plan views of underground utilities.
  • WE then creates profiles of paving and utilities, based on the point data that was used to create the plan view.

Input:

  • ASCII file with survey data
  • Point description files that will need to convert the ASCII files to a DWG file format.
  • A video drive-by of the project site to further help understand what the project site actually looks like.
  • Measure-down notes made by survey crews by opening manholes to get flowlines, pipe diameter, and the direction of pipe run, for both sanitary and storm sewers.
  • A sample set of plan and profile sheets with the existing entities shown to illustrate to what the final product should look like.
  • The CAD standards of the client, instructing about the graphical elements in the drawing (layers, font sizes, line weight etc.)

Project Steps:

  • Study of the area from video file
  • Study of point description file to understand all line items
  • Creation of base file from ASCII data (survey data and point descriptions),  using the video file to understand the terrain as and when required
  • Redlining of base file
  • Creating profiles for existing features:
  • Creating natural ground (left, right & center) using existing surface
  • Creating existing pavement gutter (left, right) using survey data.
  • Creating existing storm and sanitary sewers using measure downs
  • Creating existing water lines using existing record drawing
  • Creating plan and profile sheets for existing features
  • Redlining the existing features plan and profile sheets
  • Studying preliminary design (proposed water line)
  • Placing proposed water line in the base file
  • Placing proposed water line profile in profile sheet
  • Creating proposed plan and profile sheets
  • Redlining proposed plan and profile sheets

Output:

  • Cover sheet
  • Index sheet
  • Base file or over all file
  • Individual plan and profile sheets

Software Used:

  • Autodesk Civil 3d
  • AutoCAD
