Construction Manager at RiskProject Overview and Performance Jenica Keller, PE Assistant Chief of Project Management NDOT
Procurement Strategy • Solicitation: RFP and Interview • Evaluation & Selection process: • Qualification based • Best Value (qualification + Fee)
ICE 2 CMAR Process • ICE 3 • OPCC 2 • OPCC 3 • ICE 1 GMP Partnering • OPCC 1
NDOT Experience • 4 projects • Diverging Diamond Interchange, pavement, structural and tunnel rehabilitation, ITS and bike path • $1.5M to $31M • Others under consideration
Moana Lane • Location and Scope • I-580 at Moana in Reno • Construct DDI • $7M Improved Efficiency & Safety … Same Footprint
Moana Lane • Why CMAR? • Adjacent local agency project • High traffic volumes • Subgrade issues
Stateline to Stateline Bikeway • Location and Scope • US-50 near South Lake Tahoe • Construct multi-use path • $1.5M
Stateline to Stateline Bikeway • Why CMAR? • Environmentally sensitive area • Intense multi-agency coordination • Very short construction season during peak tourist activity
Carlin Tunnels • Location and Scope • I-80 at Carlin • Rehabilitate pavement, structures, tunnels and lighting • $31M
Carlin Tunnels • Why CMAR? • State of the art LED Tunnel Lighting • Environmentally sensitive area • Unknown bridge deck conditions • Tight working conditions • Availability of labor/housing
Kingsbury Grade • Location and Scope • SR-207 near South Lake Tahoe • Rehab pavement and drainage • $15-18M .
Kingsbury Grade • Why CMAR? • Environmentally sensitive • Very short construction season during peak tourist activity • MOT and schedule • Utilities • Groundwater • Stakeholders
How are we doing? • Innovation • Budget • Schedule • Risk
Program Performance - Innovation • Multiple GMPs: • Early procurement of materials • More scope for same budget • Aggressive construction schedule/sequence • More efficient methods
Program Performance - Budget • Average preconstruction cost relative to bid • 1.8% CMAR • 1.5% ICE • Average difference in bid • -2.8% CMAR/ICE • 1.6% CMAR/Engineer • Average savings from innovation • 11.7%
Program Performance – Schedule • Contractor’s input improved the schedule by identifying multiple shifts, increased production rates, etc. This resulted in reducing overall construction duration.
Program Performance – Risk • Risks identified and mitigated during design • CMAR owns quantity risk • Average risk reserve budget relative to bid • 2.5% CMAR • 3-5% for DBB • Trend shows risk reserves are adequate with budget remaining (NDOT retains) at closeout • Budget related change orders = 0
What lessons have we learned? • Program • Procurement • Construction
Lessons Learned - Program • Designate an executive level champion • Learn from others • Ensure industry support • Form an internal program team • Evaluate each step along the way and adjust • Known, fair and followed!
Lessons Learned - Procurement • Communicate project goals, evaluation criteria • Past CMAR experience wasn’t required • Consider a pre-proposal meeting • Evaluation and Selection: multi-disciplinary team; E&S plan; orientation/training • Allow industry/FHWA to observe • Offer debrief meetings
Lessons Learned - Construction • Earlier communication and coordination leads to higher quality • Overrun/Underrun Risk • Easy to implement: not a significant culture change and minimal process changes required
Conclusion • CMAR has been successful • NDOT will continue to use CMAR
