    Complex Projects – Overview

     CMGC Delivery Method Introduction –What is CMGC? – Added value from early contractor involvement

     I‐25/Arapahoe CMGC Project – Overview, status, benefits of CMGC delivery

     E‐470 Widening CMGC Project – Overview, status, benefits of CMGC delivery

    Introduction to CMGC

     CMGC – Construction Manager/General Contractor

     Involves a Contractor (or team) in Both the  Design and Construction Phases of a Project

    Introduction to CMGC

  • RMACES 2017 – Merging Talent with Technology to Improve Performance

    CMGC – Delivery Method

     Owner Selection of CMGC Method – Project Delivery Selection Matrix (CDOT)

     Not for Use on Every Project  Unique Projects – Aspects Include:

    –Major risk elements – Schedule, phasing complexity – Need early contractor input to mitigate risk

  • RMACES 2017 – Merging Talent with Technology to Improve Performance

    CMGC – Overview of Process  Contractor Selected Early in Design  Partnership with Owner, Designer  “Project First” Approach for Decisions  Collaboration, Communication, Cooperation  Cost, Schedule, Risk Evaluated with Every 

    Design Decision  Have “Sat at the Table” Throughout Design 

    Gives a Great Understanding of What We’re  Building

  • RMACES 2017 – Merging Talent with Technology to Improve Performance

    CMGC – Contractor’s Role  Early Estimate – Cost Model/Owner Budget  Schedule  Risk Identification and Mitigation  Innovation  Constructability Review  Quantity Reconciliation  Contract Language/Specification Review

    – NOTE: ALL THESE APPLY TO BOTH PRIME AS CMGC  AND SUBCONTRACTORS INVOLVED DURING  PRECONSTRUCTION

  • RMACES 2017 – Merging Talent with Technology to Improve Performance

    CMGC – Added Value

     Reduction of Risk for Owner, Contractor – Build schedule early – Phasing opportunities

     Subcontractor Involvement  Pavement Type Selection  Cost Estimate Approach – Full Understanding 

    of Project Risk, Constraints, Schedule, Phasing  Opportunities for Risk Pool/Risk Items

    I-25 and Arapahoe Road Interchange

  • RMACES 2017 – Merging Talent with Technology to Improve Performance

    Project Overview

     Scope: Reconstructed Existing Interchange  Owner: CDOT  Contract Value: $52MM   Schedule:May 2016 to July 2016  Asphalt Paving by Brannan Sand and Gravel  77,000 Tons of Permanent Asphalt  14,000 Tons of Detour

  • Project Challenges  Traffic and 

    180,000+ Vehicles  per Day

     Tough Access  Difficult Phasing  Significant Grade 

    Changes on  Arapahoe and I‐25

  • Current Status

    CMGC Benefits During Bid  Multiple Plan Reviews as Designed Developed

    – 30%, 60% and 90% Plans  Met with General Contractor to Discuss Phasing 

    and Schedule  Discuss Expected Productivity and Number of 

    Mobilizations  Compared to Bid‐Build Projects  Don’t Know the GC’s Phasing  Minimal Time to Prepare Bid  Low Bid and Not Best Value
