1 ATCs in DB: Minnesota DOT’s Perspective Peter Davich MnDOT Design-Build Program Manager 1

2 MnDOT: ATC Statistics DB Projects with ATCs: 22 since 2002 Total ATCs Submitted: 570 Total ATCs Approved: 352 (62%) Total ATCs Approved Without Conditions: 80 (14%) ATC Utilization Rate (Incorporated into Tech Proposal): 94% ATC Categories with the Highest Success Rates: Geotechnical – 79% Grading – 74% Materials/Walls – 71% ATC Categories with the Lowest Success Rates: Paving – 46% (MnDOT now disallows some paving ATCs) Geometrics – 49% Electrical – 50% 2

5 MnDOT: ATC Cost Statistics* ATC Cost Savings over the Life of MnDOT’s DB Program: $45.0 million Cost Savings of all Approved ATCs (including unsuccessful teams): $107.4 million Individual ATCs with Largest Cost Savings: Hastings ATC#2 “Tied Arch Alternate” $4,600, /494 ATC#4 “Move Ramp G”$3,000,000 TH 212 ATC#1 “TH 212 Profile Grade Change$2,300,000 Recent Project Total ATC Cost Savings: I94 Reconstruction$1,555,000 I-35E MnPASS$3,375,000 TH 169/494 Interchange$6,545,000 *Note: Cost savings are as estimated by DB Teams 5

6 MnDOT: Two-Stage One-on-One Meetings Offer meetings ~3 weeks into procurement “Dead on Arrival” or “Entertainable” Bring appropriate personnel -Keep meetings small, 5-on-5? -Maintain confidentiality No : note-taking coaching (but should point out risk areas) ‘stealing’ ideas (even for some mistakes) clarifications, unless ATC-related discussion of scoring 6

7 MnDOT: ATC Process Continued # of ATCs limited (5-25) Identify appropriate reviewers, read details carefully and write conditions carefully Management reviews: protect DOT interests and promote innovation Respond within 7-10 days 7

8 MnDOT: Pre-Approved Elements (PAE) Can be thought of as a required ATC – Designed to mitigate risk for both parties – “Approved” vs “Equal or Better” – Back-and-forth discussion (“coaching”) is allowed…and necessary. MnDOT Applications – Hastings Bridge: Redundancy, Scour, Fixity, Analysis Method – TH 610: Pavement Design 8

9 MnDOT Resources Instructions to Proposers template (ATC Process): – General Design-Build Information (Laws, Project Info, Etc) – Forms/Other: – – Form 2.4a for Confidentiality Template – Form 4.9a for ATC Log, 4.9b for ATC Approval Template 9
