L FAVAVA APPENDIX A SCOPE OF ADDITIONAL SERVICES South Main Street to Lafayette Connector Our Design Agreement was originally based upon our proposal dated August 9, 2010, with the Agreement executed on August 23, 2010. Since that time the Agreement has been supplemented on three times. It was modified two times to add (1) R/W acquisition services and (2) relocation agent services. The third supplemental increase (Submitted on October 12, 2011) covered the change in design from the construction of the first project of 3- Phases into one project with revised and additional alignments and traffic signals replacing the initially planned roundabout. At the time of the third Supplemental, increased design fees were projected to carry the project through Construction Contract letting and begin construction. However additional design and coordination tasks have been requested that are beyond the vision available at that time. It is noteworthy to mention that the existing agreement in -place at the time of the first planned contract letting on May 29, 2012 would have substantially covered our increased design costs. However a prudent decision made at that time (to delay the contract letting and construction until 2013) by the City and its design team was instrumental in saving user costs and most likely construction change orders due to wintering the project. This delay resulted in several additional survey, design and coordination tasks including plan revisions to accommodate R/W acquisition changes, additional street lighting, and a separate demolition project. The following items are requested as effort not envisioned in our October 2011 Supplemental Request: Additional Survev Items • Additional field survey. • Field layout of the proposed design to facilitate plan interpretation • Preparation of additional easements and parcel plat revisions. • Supplemental title information requests. Additional Design Tasks • Design and plans for decorative City street lighting. • Analysis, design and plans for an additional detention pond and outlet control structure to serve the Caroline Properties (Gates) development. • Water line extension added on East Barbie Street. • Two additional plan revisions for the Carl Kay Parcel. • Traffic analysis and multiple drive revisions for Lock Joint Tube. • Design of a construction access driveway for Heraeus Kulzer. • Quotation project and documents for a separate demolition contract of three parcels. • Additional survey and design work for West Chippewa (south side). • 2 n Letting and Construction Documents • Wendy's drive revision September, 2012 Page 1 Project File No. 9022.14
