Impact of Change Orders

• Total Dollar Amount of Contracts
• 2006 1,066,157,841.28
• 2007 1,499,430,990.85
• Total Amount of Change Orders
• 2006 Contracts
• 62,487,872.07 (and still growing)
• 2007 Contracts
• 86,939,772.99 (and still growing)

Change Orders Due to Plan Omissions

• 2006 Plan Omission Change Orders to Date
• 13,773,254.15
• 22 of change orders due to plan omissions
• 2007 Plan Omission Change Orders to Date
• 10,066,748.90

  Orders on 2006 2007 Contracts)
• 1 Spent in Design
• SAVES 10 in Construction

Bottom-line

• By Spending 14,942,764 more in the Design Phase
  for the 2006 2007 Contracts, the Cabinet could
  possibly have saved

An Evaluation of Constructability Reviews

• Where we started
• KTC Report Constructability Issues on KYTC
  Projects
• KYTC HD-204 ADMINISTRATIVE PROCEDURESFinal
  Design
• KYTC HD-209 ADMINISTRATIVE PROCEDURESDesign
  Participation in Construction Phase

PROJECT
21
An Evaluation of Constructability Reviews

• Where we started continued
• Constructability Review on all projects with
  plans
• 2 phases
• CR 1Before ROW plans are finalized
• CR 2End of Final Design
• Use the Lessons Learned Database in all phases
• Multidisciplinary teams (construction, traffic,
  operations, geotechnical, and others)
• Consistent in all districts
• Post-Construction Review
• Discussion and learning from project issues

PROJECT
22
An Evaluation of Constructability Reviews

• Where we started continued
• Lessons Learned Database
• Managed by the Value Engineering Section Head in
  Highway Design
• Populated through constructability and
  post-construction review meeting minutes and
  change order reviews by design

PROJECT
23
An Evaluation of Constructability Reviews

• Where we are
• Constructability Reviews are not done on all
  projects
• Lessons Learned Database is not getting populated
  or used as intendedUPDATE UNDERWAY
• Forming multidisciplinary teams is difficult
• There is not consistency throughout the districts
• Design is not being included in the review of
  change orders

PROJECT
24
An Evaluation of Constructability Reviews

• Barriers Perceived Problems
• Cooperation and correspondence is not developing
  as intended
• Staffing and time shortages
• Losing knowledge through retirements/turnover
• Guidance not kept up-to-date
• Lessons Learned Databasedifficult to use and
  forgotten

PROJECT
25
An Evaluation of Constructability Reviews

• What we (Construction) can do to help
• No doubt that multi-disciplinary teams provide a
  benefit to the Design and Construction process,
  we need to participate
• We need to build communication lines with design
• We need to involve design in the change order
  process
• We need to respond when called upon
• We need to include the process in our Guidance
  Manual and present it at the RE Meeting

PROJECT
26
An Evaluation of Constructability Reviews

• Some recommendations to reflect on
• KTC report
• Use retirees in reviews
• District Champions for Constructability Reviews?
• Update guidance for uniform district practices
• Division of Construction
• Short reviews for projects that do not warrant a
  full Constructability Review
• 4-hour review onsite at plan completion

PROJECT
27
An Evaluation of Constructability Reviews

• What is working well
• Post-Construction Reviews
• A great learning experience for all
• Fosters communication that needs to spill over
  into other aspects coordination between
  Construction and Design

PROJECT
28
An Evaluation of Constructability Reviews

• What we need most of all
• COMMUNICATION
• A Collaboration of Design Construction
• Doing it Right the First Time!
