Constructability ReviewPurpose: Improve the total quality of construction
bid package. Leverage the experience and knowledge

Fixing problems caused by the unknown Fixing problems caused by mistakes
What is the Goal??? Prevent Problems
or Fix Problems

(CRT) Budgeted for and Assembled by PM The project complexity will determine

Constructability Reviews Further CRT Engagement
Stage 3 of Design Checklist Item 8.02 and 8.05.
Combine if possible as last Constructability Review
Confirms issues have been addressed through:
Design alterations to avoid conflicts Well coordinated utility relocation plans
Confirms ID of Critical Path Utility Issues
Constructability Review Summary
Well executed review included in process from beginning to letting
Aids in developing: Improved total quality of construction
documents Lower change order costs Less delay/claims Higher quality end product
Potential Benefits to Utilities/INDOT Simpler, cost effective relocations Eliminate need to relocate

Adaptable. Covers most situations.
Uncommon Utility situations may require Unique Special Provision (USP)
USP must be clear and defendable Consult INDOT Utility Section!!!
For added clarity….list relocations first
UC is responsible to be sure the information shown here matches the relocation plans/documents.

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.
