It is OK to add email addresses here.

Does all of this information agree with all of the other construction documents???•Plans, Special Provisions, Utility Agreements, Relocation Plans, etc.

IT SHOULD IF UC DID THEIR JOB!

BAD WORDS

Are these dates and durations accurately reflected in Gantt Chart? Have you, as UC, followed up regularly with Utility to confirm?

Construction (Post Letting) We made the letting We have a low bidder The contract is awarded Utility Coordination is OVER! It’s construction’s problem

now….

Wrong!

Construction (Post Letting) Utility Coordination will take

place until the relocations are complete! Pre-construction Conference

Generally first time all parties meet Field Staff Contractors Designers Utilities Others

All have different responsibilities UC will be proactive in making sure Utilities

engage!!!

Construction (Post Letting) Utility Coordination

All jobs have some form of progress meetings Utility Coordinator should attend until a point where

coordination efforts are no longer needed. If proactively communicating with utilities and field

staff: Coordinator is not there to learn what is going on but should be educating others as to what is current, what is coming, and what is complete!

Construction (Post Letting) Typical Project

Survey Clearing right-of-way Contract documents contain information

regarding status of utilities and how relocation work relates to Survey and Clearing R/W

It benefits everyone (INDOT, Contractors, Utilities, Public) to work together to progress the work to complete projects on time and on budget.

Construction (Post Letting) Shop Drawings

Example: Mechanically Stabilized Earth (MSE) Retaining Walls.

Vendor Systems vary. What is shown in the plans is typically

less than what is submitted in Shop Drawings.

Lengths and Elevations of Leveling Pads vary slightly from plans. Can effect Underground Utilities.

Mislocation Scenario:

PE/S calls you and says they found a water service line that is 15’ away from where it was shown on the plans and is in conflict with a new curb inlet. Contractor moved on to other pipe and structure work but said he needs to complete this within a week to stay on schedule. Water company has had other relocation work and is non-reimbursable.

What are our options? What do we do? (Open Discussion)

Mis-relocation Same Kind of Scenario:

PE/S calls you and says a water service line was relocated 15’ away from where it was shown on the approved relocation plans and is in conflict with a new curb inlet. Contractor moved on to other pipe and structure work but said he needs to complete this within a week to stay on schedule. Water company has had other relocation work and is reimbursable.

What are our options? What do we do? (Open Discussion)

Mis-Coordination (Uh Oh) Scenario:

PE/S calls you and says a water service line was relocated to the line and elevation on the approved relocation plans but is was cut when the contractor excavated the new ditch.

This WILL be a thing of the past. Very typical example of past problems. This is why drawings of significant detail

and constructability reviews are so important.
