ICE Kickoff and Constructability Review October 29-31, 2013
NDOT • FHWA • CH2M HILL Welcome and Introductions
A document that: • Describes the methodology for preparation of the ICE for Project Neon • Presents and defines task deliverables • Will be refined during advancements of WBS, quantities, and cost development phases Independent Cost Estimate (ICE)
“A process that utilizes construction personnel with extensive construction knowledge early in the design stages of projects to ensure that the projects are buildable, while also being cost-effective, biddable, and maintainable.” – The AASHTO Subcommittee on Construction A Structured Team Approach Focused On Function(s) and Thinking Outside The Box Constructability Review
Constructability reviews that take place relatively early after conceptual design have the best potential for providing meaningful benefits without adversely impacting the schedule. Constructability Reviews
Each technical discipline or project participant group should look for opportunities to provide constructability input that will support the key project objectives of: cost and schedule reductions, quality and safety improvements, environmental protection, and risk mitigation.

PURPOSE:To present the Independent Cost Estimate Methodology (ICEM) in the preparation of a reasonably reliable and accurate Independent Cost Estimate (ICE) for the 30% Design. Independent Cost Estimate (ICE) Kickoff – PURPOSE
SCOPE: The report objectives are to… • Identify the methods and processes that will be used to develop the ICE during the 30% Design Level Phase • Identify the source documents and/or methodology that will be used to quantify and price the work, and for scheduling and risk assessment • Specify how estimating assumptions will be documented • Describe production-based and historical unit price elements • Define the approach and methodology with respect to Bid Item Summary Groups (“D-Groups”) and standard NDOT Bid items for the WBS Independent Cost Estimate (ICE) Kickoff –SCOPE
ICE Methodology established to assure ICE is prepared in a consistent and uniform manner, with standardized methods & formatting that facilitate estimate review & reporting. Variability in each development stage and the influence of updates associated with revisions to plans dictates different estimating methods or procedures at a given milestone.

“A process that utilizes construction personnel with extensive construction knowledge early in the design stages of projects to ensure that the projects are buildable, while also being cost-effective, biddable, and maintainable.” – The AASHTO Subcommittee on Construction A Structured Team Approach Focused On Function(s) and Thinking Outside The Box Constructability Reviews - PURPOSE
Assure that the project is sufficiently detailed in the plans and specs to be constructed using standard construction methods, materials, and techniques. • Verify that the plans and specs give the contractor clear guidance and information, enabling the preparation of a competitive, cost-effective bid. • Consider the cost-effectiveness of future maintenance when the project is constructed following the plans and specs. This is NOT a Design Review Constructability Reviews - SCOPE
Constructability Guidelines for Designers describe proven constructability concepts that are valid for all designs in order to improve construction efficiency and avoid pitfalls discovered on previous projects. The Guidelines are intended to be “dynamic” in that each project should provide additional ideas, further refinements, and feedback for consideration on projects that follow. Constructability Reviews - GUIDELINES
Mobilization / Demobilization • Equipment – Placement, Availability … • Phasing / Staging • Maintenance of Traffic (MOT) • Materials – Availability, Procurement, Logistics • Structures Siting Constraints • Lightweight Fill • Drainage / Erosion-Sed Control / Environmental • Long Lead Items – Electrical • Right of Way (ROW) – Acquisition, Improvement • Safety Constructability Reviews - GUIDELINES
Review of Available Information and Schedule • Probable Sequence of Construction and Staging • Construction Contract / Special Requirements • Construction Plan – efforts to aid constructability Constructability Review
Working Groups for Next Segment of Workshop: • Group 1 (Horton & Kamph) – Roadway / ROW / Drainage / Utilities • Group 2 (Platin & Hults) – Structures / Geotech / Retaining Walls / Sound Walls / Risk Analysis • Group 3 (Parimi & Voldman) – Traffic / MOT / Electrical (Lighting / ITS / Signals) Constructability Review
AFTER BREAK…Design Leads to Kick-Off: • Discussion of Discipline Specific Constructability Review Forms – FOCUS on CONSTRUCTABILITY… NOT DESIGN • Identify Additional Construction Concerns • Prioritize Top 3 to 5 Issues • Review 30% Design Estimate • Conduct Team Focus Q&A Constructability Review
