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?

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

Answer… 105 IAC 13-3-3(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.”

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

Example 1

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?

Example 2…

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?

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

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.

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

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

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.

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.

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.

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.

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.

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.

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.

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

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

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

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

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

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

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

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

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

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.
