m', WORK PLAN Bit s The BKF Engineers' (BKF) team proposed for the City of Pleasanton's (City) Bernal at Interstate 680 Interchange Project (Project) has been working together on the development and design of highway and roadway projects for over ten years. Through our projects, BKF has built a reputation on its ability to manage, design, process and deliver Caltrans projects for local agencies and stakeholders. BKF has been singled out and specifically selected by clients to manage and deliver projects in urbanized areas involving limited right of way, schedule constraints, and public involvement,. BKF has a track record of producing cost effective designs and delivering buildable projects in these multi - jurisdictional settings. The proposed BKF work plan for the Bernal at Interstate 680 Interchange Project for the development of the Plans, Specifications and Estimate (PS &E) and Environmental Clearance considers all phases of the project from conception through the issuance of an encroachment permit as specified in the RFP. It is BKF's understanding that the City of Pleasanton wishes to improve the interchange of Interstate 680 and Bernal Avenue to add additional capacity at the northbound and southbound on- ramps. Specifically, the project includes the following improvements: • I -680 Northbound On -ramp: Construct capacity improvements for the westbound to northbound right turn lane and widen the northbound on -ramp to accommodate two lanes. • I -680 Southbound On -ramp: Construct dual westbound to southbound left turn lanes and construct 2 receiving lanes on the southbound on -ramp. For the I -680 northbound (NB) on -ramp, the dual right turn lanes into the NB on -ramp will require the widening of the on -ramp to a two lane entrance ramp. This was a proposed mitigation as identified in the Transportation Impact Study for the Pleasanton Gateway Retail /Office Plaza. Per the study, the future cumulative conditions do not degrade the level of service for the I -680 mainline and the Bernal NB on -ramp merge /diverge to unacceptable levels thus indicating that an auxiliary lane would not be required. Although the NB on -ramp volumes will exceed 1500 vehicles per hour (vph), Chapter 500 Traffic Interchanges, Section 504.3 Ramps of the Highway Design Manual identifies the need for a two -lane exit ramp for volumes that exceed 1500 vph as an advisory design standard but does not impose the same requirement for an entrance ramp. There is no mandatory or advisory design standard requiring a two -lane entrance ramp or the addition of an auxiliary lane for volumes exceeding 1500 vph; there is a recommendation but no requirement. Given that the freeway and ramp entrance operations meet acceptable operational levels per the Transportation Impact Study, it is BKF's opinion that the mitigation requirement can be met by increasing the storage of the NB Bernal on -ramp with two lanes at the local street connection which merges to an one -lane entrance ramp as demonstrated in Exhibit A found in Section 5, Supportive Information of this Proposal. Our work plan is therefore structured to provide an encroachment permit through a Permit Engineering Evaluation Report (PEER) and obtain a Categorical Exclusion and a Categorical Exemption for environmental clearance for the I- 680 NB and SB on -ramp improvements which will not include the construction of two -lane on -ramps or auxiliary lanes. A summary of our proposed work plan for the Project follows below. A breakdown of the needed staff resources and work hours to support each task of the work plans has been provided in the Work Hours and Cost Estimate of this Proposal: Task 1 Project Management — Duration 8 -9 months concurrent with other Work Tasks BKF's Principal -in- Charge /Project Manager (Project Manager) will be responsible for managing the project team including the subconsultant team, providing the resources to complete the job, monitoring and updating the Project budget and schedule, implementing a quality assurance /quality control program and communicating regularly with the City, Caltrans, FHWA, jurisdictional agencies and stakeholders. BKF's Project Manager will keep the City informed by close communications on a day -to -day basis and be continually available to City and Caltrans as needed. To maintain the Project schedule, BKF will act as strategic counsel by flagging issues, providing recommended solutions for discussion and implementing the accepted action. On a monthly basis, BKF's Project Manager will review, prepare and submit status on budgets, progress, schedule, performance and document any changes in design scope, cost or schedule. This information will be summarized in a monthly progress reports and updated schedules. BKF will ensure that coordination with the City, Caltrans and other stakeholders is enhanced via regularly
