2. Introduction… What is a drawing of sufficient detail?
What is the purpose of a drawing of sufficient detail?
What are the components of a drawing of sufficient detail?
Why is a drawing of sufficient detail important?
What happens when a utility cannot or will not produce drawings of sufficient detail?

3. What is a drawing of sufficient detail?
Question…
What is a drawing of sufficient detail?

5. Answer…
105 IAC (c)6 states that the work plan shall include the following… “A drawing of sufficient detail and scale to show the proposed location of the facility relocation.”

6. Answer… According to the rule, the answer is… Detailed Scaled
Shows proposed facility relocation
According to the Code, a drawing of sufficient detail is…

7. Example 1

8. Let’s Discuss…
Looking at the rule’s definition, is this drawing a drawing of sufficient detail?
Is this drawing detailed?
Is this drawing to scale?
Does this drawing show what the proposed relocation is?

9. Example 2…

10. Let’s Discuss…
Looking at the rule’s definition, is this drawing a drawing of sufficient detail?
Is this drawing detailed?
Is this drawing to scale?
Does this drawing show what the proposed relocation is?

11. What is the purpose of the drawing?
Question…
What is the purpose of the drawing?

12. Answer…
To enable the utility coordinator and design staff to determine if the proposed facility relocation will resolve all known facility conflicts with the proposed design without causing additional conflicts with other utilities’ facilities or with the project.

13. Let’s Discuss…
Which drawing assists you in achieving the purpose and need for a drawing of sufficient detail?
Why?

14. What are the components of a drawing of sufficient detail?
Question…
What are the components of a drawing of sufficient detail?

15. Drawing of Sufficient Detail
Must use the INDOT Plans
“INDOT PLANS” REFERS TO THE USE OF THE DESIGN PROFILE, ALIGMENT, STATIONS, RIGHT-OF-WAY.
This is the only way that anyone looking at the drawings can see if the relocation plan addresses all of the conflicts.

16. Drawing of Sufficient Detail
How can they be submitted?
May mark up the PDF provided by the Designer
May mark up a hard copy provided by the Designer
May provide a CAD file that uses the Base files as provided by the Designer
May provide a pdf of plans on their title block
This is the only way that anyone looking at the drawings can see if the relocation plan addresses all of the conflicts.

17. Drawing of Sufficient Detail
Uses the project alignment for stations and offsets
Poles, anchors, and guy wires
Fire hydrants
Crossings-station only unless termini are in the right-of-way
Vaults, hand holes, manholes
Bore Pits
Control cabinets, pedestals
This is the only way that anyone looking at the drawings can see if the relocation plan addresses all of the conflicts.

18. Drawing of Sufficient Detail
Provides elevations
For all underground facilities
Maximum elevation at top of facility when under Pavement, structure, ditch
Minimum at bottom of facility between facilities
NOT x’ below grade – which grade?
This is the only way that anyone looking at the drawings can see if the relocation plan addresses all of the conflicts.

19. Drawing of Sufficient Detail
Provides cross sections showing facilities
Distinguishes between:
Proposed facilities
Existing facilities
Retired facilities
Existing facilities to remain
Existing facilities to be removed
Distinguishes between aerial and underground
This is the only way that anyone looking at the drawings can see if the relocation plan addresses all of the conflicts.

20. Drawing of Sufficient Detail
Method of installation
Direct Bury
Bore
Type and size of pipe to be installed
Any critical clearances needed
Notes any areas of concern especially to facilities remaining in place
EX. – holding a pole, holding a pipe, etc.
This is the only way that anyone looking at the drawings can see if the relocation plan addresses all of the conflicts.

21. Drawing of Sufficient Detail
Helpful hints…
Develop a checklist to use while reviewing drawings to ensure minimums are provided
Best Practices list developed by INDOT
This is the only way that anyone looking at the drawings can see if the relocation plan addresses all of the conflicts.

22. Drawing of Sufficient Detail
A Note about “abandoning facilities”
A utility may not abandon their facilities
They may “retire in place”
The may designate a facility as being “temporarily out of service.”
For either of the above designations we should place a red “X” over the facilities

23. Drawing of Sufficient Detail
CAD files versus PDF versus Hard Copy
Some utilities will request CAD files
Ask what platform and version is used
Many consultants will ask for an electronic file transfer agreement – check with your company to determine if this is required.
Some utilities will mark up a pdf
This is okay if they provide the necessary detail
Some utilities request hard copies

24. Why is a drawing of sufficient detail important?
Question…
Why is a drawing of sufficient detail important?

25. Answer…
Must be able to determine WHERE the facility will be as it relates to the proposed design
Must be able to determine if required clearances are met
Must be able to ensure environmental commitments have not been compromised

26. Answer… Must be able to identify potential constructability issues
Must be able to ensure that facilities are within proposed right-of-way
Must be able to verify and/or identify conflicts with other facility relocations

27. Question…
What happens when a utility cannot or will not produce drawings of sufficient detail?

28. Answer…
Some utilities do not have the personnel, expertise, or experience to produce a drawing of sufficient detail
Let the project manager know
Include in the risk report
Meet with a representative on site
Discuss the specific issues related to the need for relocation
Discuss options for relocation
Determine if there is any way to include the relocation in the project

29. Answer…
Some utilities refuse to provide a drawing of sufficient detail
Let the project manager know
Include in the risk report
Meet with a representative on site
Identify why they will not provide a drawing
Review the plans with the utility representative and work together to determine with the best of our ability the station and offset of the facility
Provide minimum elevations if necessary

30. Answer…
Try to gain concurrence from the utility representative when providing the station, offset, and elevation
Contact a supervisor at the utility if cooperation is still not achieved
Document EVERYTHING

31. Note…
The rule does NOT make it clear what a “drawing of sufficient detail” is.
Utilities may have a different perspective or definition.
Utilities have not received training on what is expected.
Work with the utilities to achieve a drawing of sufficient detail.
