• Accelerated project completion.
PROS OF DESIGN BUILD
• Generally, final cost less than initial cost estimate.
• Benefit of having facility available to public.
• Positive public perception.
• Reduced timeline for Right of Way acquisition.
CONS OF DESIGN BUILD
• Increased condemnation perception.
• R/W acquired and cleared in accordance with Uniform Relocation Assistance and Real Property Policies Act of 1970, as amended, and state R/W procedures.
FHWA Requirements
• R/W certification must be submitted to and approved by FHWA prior to work commencing on individual tracts or entire project.
FHWA Requirements
• Request for R/W services must be included in request for proposals.• Design/Builder must submit written acquisition and relocation procedures to STD for approval; should contain appraisal, acquisition, and relocation strategy.
Role of SCDOT
• Develop a concise RFP.
• Provide an on-sight R/W Project Manager as single point of contact with authority to approve all settlements and provide tract certification.• Provide constant oversight to insure all federal guidelines are adhered to.
Lessons Learned
• Assign Project Manager and authorize to approve just compensation, appraisals, relocation, administrative adjustments, etc.
• Establish “critical path” for construction and stage R/W and relocation accordingly.
• Identify new methods to handle R/W issues; i.e., purchase of improved property without appraisal including establishment of total benefits to landowner, use of auction company for disposal of 14 homes (less than 3 years old).
