In addition to the Scope of Services outlined above, The Consultant shall also complete the following Scope of Services as part of Contract Change Order No. 1:
Task 2: Research Existing Conditions, Surveys
The Project's Surveyor identified three (3) alley segments that were PRIVATE and such realization required to replace the three (3) private alley segments with alley segments that were located within Corona's Public right-of-Way, as to meet the Clean California Grant stipulations, and that their cumulative length was similar; hence, a survey of the new replacements alley segments was necessary to design the proposed alley improvements. To ensure compliance with the grant scope of service additional topographic and boundary survey were obtained for the new alley which is 477-ft long and spans from Eighth Street to Sixth Street and between Harris Street and Buena Vista Avenue (refer to Figure 1 for Alley Locations Map).
Task 3: Final Engineering and Preparation of Construction Contract Documents:
Caltrans approved the alleys replacement, and therefore the design for the proposed alleys improvements was necessary (this cost was deduced from a proportionality represented by the new alley segments' length in relation to the Original Project Fee Schedule).This change resulted in additional grading design of the two alley segments, updating 2D/3D base map files, plan and profile sheets, solar lighting sheets, construction notes, labeling, and curve/line tables. In addition, the plan sheets that included the alley segments that were removed also had to be updated to reflect the new changes.
