Mr. Mike Tassano � March 25,March 25,2014 ®® Page 3 BK F SHPO Submittal and Approval During the design development phase of the Project, Caltrans indicated that the I-680/Berual ENGINEERS Avenue Interchange was within an area that had been identified as archaeologically sensitive. SURVEYORS This created significant amount of work and effort associated with obtaining Caltrans and regulatory approval for any construction within the area. In order to obtain concurrence on the PLANNERS proposed work required by the Project, a Historic Resources Compliance Report outlining a testing and monitoring program had to be prepared and submitted to Caltrans and the State Historic Preservation Office(SHPO). The report required site visits, conducting initial surveys, modifying design to minimize excavation within the culturally sensitive area and creating exhibits of Project features and depths of excavation. The document was reviewed by Caltrans and comments incorporated prior to submission and approval by SHPO. This effort totaled $8,800. It was hoped to absorb this extra work effort into the existing design budget but it appears that the work associated with the landscaping and gateway elements may also expand due to the work associated with working within the archaeological area Any additional SHPO coordination necessary due to discoveries during the testing program is excluded from this scope of work Caltrans Rider for Additional Work Scope After obtaining Caltrans approval on the Project plans and specifications, the City provided BKF with comments on July 18,2013 and September 18,2013.Given the late receipt of the comments; the more inconspicuous comments, which comprised the majority of the comments, were incorporated to ensure competitive pricing would be received during bids with the understanding that the revisions would have to be subsequently submitted to Caltrans for approval as a rider to the Caltrans encroachment permit. Although it is BKF's hope to absorb this extra work, the timing of the comments required additional effort with Caltrans and revisions to the design that could otherwise have been incorporated into earlier submittals. Due to the timing of the amendment and necessary council approval,the budget for this effort was deferred from contract amendment#4 to contract Amendment#5. This cost of this extra work is $7,500. Additional more significant comnients.as were outlined in Amendment#4 were incorporated and were also included in the bid set. These comments were included in the bid set but were not included in the Caltrans Encroachment permit set and will need to be processed through Caltrans for a permit rider. Due to the timing of the amendment and necessary council approval, the budget for this effort was deferred from contract amendment#4 to contract Amendment#5. The cost of this extra work is$20,000. Caltrans is currently in the process of designing improvements to NB I-680 and has identified potential revisions to the drainage design that will allow for the coordination between the City and Caltrans projects. Two drainage configurations (dated 12/26/13& 2/8/14)were submitted to BKF for review,and one was implemented into the City PS&E requiring changes to the plans and estiniates. The cost of this extra work is $2,500. The City performed a review of the bid set and issued comments dated February 24,2014. These 4670 O® !2014 comments required additional effort due to a new specifications boilerplate, lane configuration ®250 revisions to EB Banal between West Lagoon Road and the 1-680 SB Off-ramp, traffic signal m phasing revisions at the Bernal/I-680 SB off-ramp, revisions to LED of illuminated signs, 94588 revisions in overlay limits, and minor revisions to traffic handling, construction area signs, and on 925.396.7700 ®925.396.7799 1 E13 micuu.
