Summary and Discussion At the April 25, 2013 Rail Committee meeting staff presented a fee proposal from Hatch Mott McDonald (HMM) that outlined the costs associated with doing a 10% design on two grade separation alternatives. Those two grade separation alternatives were: 1) submerging the roadway at Palo Alto’s four at-grade crossings; and 2) depressing the Caltrain corridor in an extended trench from the south end of the downtown Palo Alto Caltrain station to approximately San Antonio Road. At a cost of $2,614,745.60 for HMM to do a 10% design for those two scenarios the Rail Committee, at the recommendation of staff and HMM, requested a fee proposal from HMM to develop conceptual grade separation alternatives instead of doing a 10% design. Since that meeting, HMM has provided the City of Palo Alto with a fee proposal to develop conceptual grade separation alternatives, instead of doing a 10% design, for the same two scenarios mentioned above (submerging the roadway at at-grade crossings and trenching). This fee proposal incorporates comments HMM received at the April 25th meeting and would provide the City with accurate cost ranges and orders of magnitude for the above mentioned scenarios. The impact in this change in scope is a reduction in cost from $2,614,745.60 for the study to $127,550. The study will not be as detailed as the 10% design but will deliver a “relative concept cost estimate for each alternative.” City of Palo Alto Page 2 Currently, $64,688.33 is remaining in a contract with HMM for on-call engineering design services meaning the City Council would have to appropriate an additional $62,861.67 for this work. On Tuesday, May 14, 2013 staff met with HMM to discuss their revised proposal. During this meeting staff requested HMM break-down the $127,550 figure in two ways: 1) how much of that figure is for studying the submersion of the roadway at at-grade crossings and how much is for studying trenching; and 2) after HMM mentioned they could do some of the work in phases how much each phase would cost. The goal of a phased approach would be to allow the Council to decide whether to move forward with a second phase after hearing the results of the first phase. HMM could not provide that information immediately but will have it available to discuss at the May 23, 2013 Rail Committee meeting. Attached is the revised proposal from HMM that outlines how they would develop conceptual grade separation alternatives for Palo Alto, instead of doing a 10% design, for the two scenarios mentioned above (Attachment A). This proposal outlines the anticipated scope of services, study approach, deliverables, fee proposal, and contractual framework to be expected if the City decides to approve this study.

Services to be provided will include the following: • Alternative evaluation and identification of potential project impacts, both permanent and temporary, including such items as - roadways, right of way, traffic, utilities, and the railway corridor. • Development of alternatives to a concept level, to include feasibility study report, concept design exhibits, and order of magnitude project costs for evaluation purposes. • Attend a total of three public meetings (two City Council Rail Committee meetings and one City Council Meeting) to present the alternatives and obtain input. This scope and fee estimate is provided for conceptual grade separation alternatives at the following four locations: • Alma Street/Palo Alto Avenue • Churchill Avenue • Meadow Drive • Charleston Road It is assumed that existing grade separations at University Avenue, Homer Avenue, Oregon Expressway, Embarcadero Road, and existing creeks would be retained in their current configuration. Though reconfiguration of these locations will not specifically be included in the study, any impacts to these facilities associated with any of the conceptual grade separation alternatives will be noted. At each crossing location HMM will investigate potential grade separation methods involving taking the Caltrain corridor under the existing crossing roadway, taking the crossing roadway under Caltrain, or partially raising of one system in conjunction with partially lowering the other system. The proximity of Meadow Road and Charleston Road, and limitations on maximum freight rail grades may necessitate a single solution at this location. 2.0 Study Approach 2.1 Assumptions The predicted level of effort associated with the study and the corresponding fee proposal are based upon a number of primary assumptions as identified below. City of Palo Alto Rail Analysis Study – Scope of Services & Fee Proposal 2 • Caltrain service will be electrified prior to performing the grade separation. Caltrain will remain operational throughout the duration of the construction • Limited freight service will continue to operate on the Caltrain corridor. • Alma Street may be used in part for the construction of shoo-fly tracks. • The following documents will be used as the basis of the study: o Rail design will be based upon published Caltrain Design Criteria and Standards: http://www.caltrain.com/about/doingbusiness/engineering/engineeringstandards.html o The Caltrain Standards will be supplemented by the January 2007 Draft Criteria Manual Electrification Program o Overhead contact system configuration will be per Caltrain General Arrangements: http://www.caltrain.com/about/doingbusiness/engineering/Electrification/OCS_General_Ar rangement.html o Criteria for streets and roadways will be based upon City of Palo Alto Municipal Code, City Standards, planning requirements and Caltrans standards: http://www.amlegal.com/nxt/gateway.dll/California/paloalto_ca/paloaltomunicipalcode?f= templates$fn=default.htm$3.0$vid=amlegal:paloalto_ca http://www.cityofpaloalto.org/news/displaynews.asp?NewsID=1834&TargetID=145 http://www.dot.ca.gov/hq/esc/techpubs/ o California Public Utilities Commission (CPUC) General Orders: http://www.cpuc.ca.gov/PUC/documents/go.htm • Base mapping, right of way boundaries and existing utilities mapping information will be made available by the City. • Existing geotechnical data and engineering recommendations reports for existing grade separation projects, and other relevant building, utility, other projects or study information adjacent to the existing Caltrain alignment will be made available by the City. • Requirements for maintenance of traffic and ultimate traffic lane configurations will be as provided by or as agreed with the City. • Property valuations for identified right of way takes or temporary impacts for the various options will be provided by the City. • Coordination with rail regulatory agencies such as, but not limited to —California Public Utilities Commission, The Federal Railroad Administration, and the Federal Transit Agency, is not necessary at this conceptual stage. • Public Meetings would be facilitated by the City and attended by the PM and key project staff. City of Palo Alto Rail Analysis Study – Scope of Services & Fee Proposal 3 2.2 Study Team & Scope The study scope of services requires input from a multidisciplinary design team involving civil/rail, structural, and estimating services. The proposed level of effort for project management and each of the engineering disciplines is described below. Project Manger HMM will provide a project manager (PM) to oversee and coordinate the study effort. The PM will be experienced in planning, design and construction of rail and civil infrastructure and will oversee and direct the work of the study. The PM will have overall responsibility for HMM’s performance relative to schedule, budget, and quality of the deliverable products. The PM will be the principal point of contact between the City and HMM, and will attend meetings with the City and its Rail Committee. Engineering Staff Each discipline engineer will be responsible for the development of aspects of deliverables relative to their discipline – be it sections of study reports, development of exhibits, or provision of take-off quantities in support of cost estimating. Civil/Rail Engineer The civil/rail engineer will be responsible for identifying impacts to rail operations and capacity for each of the alternatives and for establishing concept level temporary requirements involving single tracking and/or shoo-fly construction, and permanent requirements for the rail configuration for each of the alternatives. The civil engineer will be responsible for establishing the extent of any impacts associated with right of way, utilities and streets and roadways for each of the alternatives. The civil engineer will develop conceptual level construction sequencing for options involving grade separations and, in conjunction with the structural engineer, will develop a series of sketches which support the feasibility of the construction sequence. Structural Engineer The Structural Engineer will develop structural conceptual level configurations for each of the grade separation alternatives for both temporary and permanent construction. Cost Estimator The cost estimator will be responsible for the preparation of the cost estimate, including the estimate basis, assumptions, and appropriate levels of contingency and accuracy. The estimator will work with the engineers to prepare appropriate costs for significant items based upon ongoing or recently bid City of Palo Alto Rail Analysis Study – Scope of Services & Fee Proposal 4 similar work. The cost estimates for each alternative will be used for relative alternative comparison only. The cost estimates for each of the options will form an Appendix to the study report. Estimating support will be required to identify appropriate pricing for any necessary right of way acquisition for temporary or permanent purposes. Quality Assurance/Quality Control In keeping with HMMs commitment to Quality HMM deliverables will be peer reviewed by Senior Personnel for technical accuracy and to ensure compliance with quality HMM’s Integrated Management Systems. 2.3 Study Approach Our approach to the delivery of the study upon Notice to Proceed is as follows: • Meet with City staff to gather existing available information, discuss apparent constraints, and review initial concepts and preferred solutions. • Prepare initial draft of alternative concepts with ‘felt pen’ type Exhibits. • Meet with City staff to agree upon which alternatives are to be developed in study and to what level they will be developed. • Prepare concept level exhibits for each alternative and initial cost estimates • Meet with City Council Rail Committee and City staff to discuss initial findings, concepts, and gather input. • Prepare Final Concept Exhibits. • Meet with City Council Rail Committee and City staff to finalize study and design exhibits. • Update Concept Exhibits and prepare • Attend City Council presentation to provide status and gather input • Compile Concept Exhibits and estimates, prepare Final Feasibility Study with summary text documenting the process, and forward final deliverables to City.
