  1. GANTT CHARTS & SCHEDULES Chris Hammond, P.E. Transportation Department Manager, United Consulting December 18, 2013

  2. 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.

  3. 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 Stage To be sure there is proper summation of Utilities’ Relocations….could affect Contractor Start Date • Construction Stage Based on actual progress made by each Relocating Utility….could lead to Contractor “delay” claim

  4. 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

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

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

  7. 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.)

  8. 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 moved • Engineer’s MOT Schedule • Engineer’s Phasing/Sequencing of CX • Contractor’s overall Scehdule
