Indiana Design Manual IDM 104-1.03 (3) Utility Coordinator
#58. Prepare a Gantt chart for all utility relocation work that reflects the start time, finish time and duration for each independent section of the utility facility relocation work. Ensure the chart has information regarding the geographical direction (east to west) the utilities are operating.

When should we do Schedules? Schedules now need completed at
3 points in time: Preliminary Stage:At/During PFC Meeting, to estimate how long
Relocations will take….could affect Letting Prior to Work Plan Approved StageTo be sure there is proper summation of Utilities’
Relocations….could affect Contractor Start Date Construction StageBased on actual progress made by each Relocating
Utility….could lead to Contractor “delay” claim

Types of Schedules INDOT now requires a visual
Schedule, such as “Gantt Project” http://www.ganttproject.biz/ Free, public domain software
You may use other programs: MS Project Schedule Excel spreadsheet Others acceptable (key is visual) Keep them as simple and practical as
possible

Gantt Charts Remember these from College?
Various types of Schedules Bar Charts (low complexity) CPM (high complexity) Gantt Charts (mid-level complexity)

Gantt Charts Advantages
Multiple work elements/tasks Tracks “Start” and “Finish” Dates Shows Durations Obvious interconnection/Relationships Visual easy to understand/interpret

Utility Schedule So why is INDOT requiring it?
To determine IF construction can be: Done without conflicts with Utilities Done simultaneous with Relocations
To avoid overlaps: Between Utilities’ Schedules vs. Contractor’s Between various Utilities’ Relocation Schedules
To help: Utilities be aware and coordinate amongst Identify “under-builds” on Aerial Electric lines Facilitate preceding activities, even Pre-
construction (acquire R/W, stake R/W, clear Trees, etc.)

Utility Schedule So what inputs are needed?
Preconstruction schedules of each Utility Relocation schedules of each Utility R/W Clear and R/W Staked Dates Direction each Utility plans to proceed Target Date Contractor wants Utilities
