Why Design-Build?1 ) Cost and Schedule
a) A Design Build project is less expensive overall than a Design-Bid-Build project.
b) The Contractor and Designer will work together to reduce costs by efficiently phasing the project and assuring that production is considered in each major component of the design.
c) The public receives the completed project much earlier.
d) Project Cost is also reduced since escalation and finance costs are lower for a project built sooner rather than later.
Why Design-Build?
2 ) Quality
a) We believe that higher levels of quality control and assurance is achieved on these type projects.
Why Design-Build?
3 ) Innovationa) More flexible because of a single responsibility for
design, construction and operations.
b) The Owner stands to gain new ideas that not only save $’s on specific projects but that can be utilized on other projects going forward.
c) The Owner should be careful to not hinder innovation by being too prescriptive.
Enhanced ConstructabilityThe Design Build process allows the Contractor the opportunity to be involved in concurrent “over‐the‐shoulder” reviews of the Designer’s efforts. This allows the Design Build Team to put forth a cost‐effective and customized project design that allows for “ means and methods” that match the Contractors past experiences, abilities, strengths and available resources.

The Contractor’s PerspectiveAdvantages of Design-Build for Kokosing
• Open venue to apply our innovation • Allows us to direct the design to our strengths• Direct access to Designer to resolve field issues
– RFI’s – 2 to 3 day turnaround
• Design Build works on any size project.• Larger, more complex projects, is where we find the
Design Build process really pays off.
Contractor’s PerspectivePre‐Bid Efforts
• Tremendous Bidding Effort Involved Up‐Front.– Coordination with Designer – Define Roles & Responsibilities.
– Ensure Common Understanding of Project Scope as Written.
– Develop, Enhance and Reach Agreement on Design Concepts.
– Technical Proposal Development/Writing.
– Detailed Pre‐Bid Schedule. Proposed dates become contractual.
– Bidding from a Very Limited set of Drawings.
Contractor’s PerspectiveNew Experience for our Employees
• Upfront staffing more intense – Commit personnel long before construction
begins for design review and optimization
• Additional staffing needs– Plan review during design– Budget control– Subcontractor coordination– Design task force meetings
Contractor’s PerspectiveOther Considerations
Subcontractors and Suppliers. Must bid off of partial plans also.
Heavily Involved in plan development.
Proper upfront staffing and planning is essential.
• Understand that 100% Project Drawings are typically not complete until well into construction.
• Open & Honest Communication. – Creates a partnering atmosphere– Expedites issues resolution– Design Build = 100’s of Meetings
• Clearly written scope is essential to a successful project for all Parties.
• Accurate and detailed Geotechnical and Environmental data needed pre‐bid.
