Mr. Mike Tassano I_ City of Pleasanton October 24,2013 mink Page 3 Bid Assistance for Roadway Construction BKF and its subconsultants will be available to attend meetings, review bids and provide ENGINEERS clarifications, addendums and written recommendations during the bid circulation period of the SURVEYORS Roadway Package. BKF requests a budget amount of$5,000 to perform bid assistance for the Roadway Package. PLANNERS 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. The cost of incorporation of the inconspicuous comments that were incorporated in the bid set is excluded from this amendment. Other comments that are more substantial in nature are pending incorporation and require additional work and effort which may have to be issued as a Contract Change Order (CCO) depending on the timing of the resolution. The comments include revisions to the design and specifications to provide a crosswalk across W Lagoon Road, the incorporation of recent electrical work performed in the area, drainage improvements under the bridge, and the use of LED lighting within the traffic signal systems. Additional supplemental field surveys will be required to design these new design features to incorporate areas that were originally outside of the immediate Project limits and changed field conditions due to recent construction. Per the City comments, a new signal plan would be required for the intersection of Bernal Avenue and West Lagoon Road. The signal modification to LED lighting at two intersections along Bernal will require lighting calculations where we assume that an IES file for the LED lights can be provided by the City or manufacturer for use in the lighting calculations. BKF assumes that the lighting calculations will yield that LED replacement light will suffice; however, if this is not the case and additional lighting standards are required, the addition of lighting standards is not included in this proposal and will be considered as extra work. Additionally, this proposal assumes that the proposed drainage improvements at the bridge abutments will not require separate processing by Caltrans Headquarters Structures Department. Should this not be the case, more effort will be required to process the change through Caltrans; this additional effort would be considered as extra work separate from this proposal. Based on previous correspondences, BKF understands that the comment requiring an asphalt overlay along Bernal Avenue will be performed by a separate project and thus is not included in this proposal. All the revisions to the contract documents made after the issuance of the encroachment permit set will require the processing and further review by Caltrans of an encroachment permit rider. 4670 Willow Road, The effort associated with the incorporation of the more substantial comments received after the Suite 250 encroachment permit, preparation of a CCO, and processing for an encroachment permit rider is Pleasanton, CA estimated at $38,000. 94588 ph 925.396.7700 Fax 925.396.7799 www•bkF com
