2 A. Pre-Proposal Conference Attendee Sign-in Sheet See Attachment A for the attendee sign-in sheet for the mandatory Pre-Proposal Conference and site walk held on December 15, B. Response to Questions submitted as of December 16, 2015 Q1: Specifications appear to have the MEP as design build subcontractors. Is WETA ok with us hiring MEP engineers and then having a subcontractor perform the work? Or are you specifically wanting these trades to be D/B subs? A1: Yes, it is acceptable to have separate MEP engineers complete the design and then hire a subcontractor to perform the work. Q2: When you say Mechanical for major participants is this just mechanical? Or Plumbing and Fire Sprinklers as well? A2: The term Major Participant has been revised by this Addendum No. 1 to apply only to Subcontractors with a proposed subcontract value greater than 15% of the anticipated Contract value. See Section D of this Addendum No. 1 for more details. Q3: You are asking for us to include information for Major subcontractors prior to pricing in our technical proposal. Is there was any possibility to submit on two subs or delete this requirement in its entirety for some of the trades such as Landscaping, glazing, Mechanical, cladding, soil mixing? A3: No, this requirement shall remain as stated in the RFP. Please note, the term Major Participant has been revised by this Addendum No. 1. Q4: What is the overall project completion target date? A4: See Section 5.2 Final Completion of Document Design Build Agreement Form. Q5: Can you describe WETA s emergency mandate and WETA s operational status during an event? A5: WETA is authorized to coordinate maritime emergency response for water transportation operations in the Bay Area using public transit ferries. Emergency water transportation operations are defined as emergency movement of survivors as well as movement of first responders and disaster service workers to support incident response. In an incident that disrupts normal regional transportation systems, WETA serves both as an authority that coordinates emergency response activities for water transportation services in the Bay Area and also as a transit agency that provides emergency water transportation resources. The Central Bay Operations and Maintenance Facility will have an emergency operations center with the appropriate set up and communication systems, including satellite phones, interoperable radios, multiple workstations etc. There is a more detailed description of WETA s emergency response mandate on the WETA website. Q6: Could you describe essential service requirements for the Facility/Project? A6: The Project is required to meet Essential Facility requirements per the California Building Code (CBC) as stated in Section Summary of Work. The Essential Facility requirements for this project, including seismic design categories and importance factors, are further noted in Design Criteria notes on Preliminary Drawings BS101 and SS101 for the Building and Site structures. Q7: Who will be issuing building permits for the project (who is the landowner)? A7: The City of Alameda is the landowner and local land-use jurisdiction that will be issuing permits for the project, including Building and Infrastructure Improvement Plan Permits as described in Section , paragraph 1.4.D. Q8: Can you talk a bit more about the design build requirements? Will there be any review of system components? There are some requirements that are very tightly laid out and others that are very open. CENTRAL BAY OPERATIONS AND MAINTENANCE FACILITY Addendum No Page 2 of 8

3 A8: In general, the Bridging Documents represent roughly 60% completion of project design by the Owner s Architects and Engineers. As set forth in Division 1 and elsewhere in the Contract Documents, the Design-Builder will be required to prepare 75%, 95%, and 100% Final Design submittals for review by the Owner for compliance with the Project Design Criteria set forth in the Bridging Documents. Q9: Will WETA release the CAD files and MS word files of the technical specifications to the successful Offeror? A9: Upon execution by the Design-Builder of a waiver agreement in the form provided by the Owner, Owner will provide Preliminary Design Drawings and Technical Specifications utilizing electronic media (i.e. CDROM or Flash Disk Drive) for use by Design-Builder where documents are available in electronic media. Q10: What is the DBE goal for this contract? How will DBEs be evaluated in the proposals? A10: There is no specific DBE goal for this contract. WETA has an overall triennial DBE goal and this contract is included in the calculation for the overall goal. An active outreach effort to obtain DBE and SBE participation is contractually required in this solicitation and is one of the items required for the proposal to be considered responsive. Q11: Is there a separate engineer s estimate for the marine portion of the work? A11: The RFP documents include an engineer s estimate for completion of the entire project (see Document Instructions to Offerors, Section 1.C). Q12: What is the overall DBE goal for WETA and where are you in the goal period? A12: WETA has an overall triennial goal of 1.36% which is based on an analysis performed in the spring of 2013 of the federally funded contracts that WETA expected to let during the period FFY WETA is required to meet the triennial goal for each year of the three year period. WETA is in the last year of the current triennial goal. Staff will be preparing an analysis this spring for submission to FTA this summer for the next triennial period covering FFY Q13: You mentioned that the ACOE permit is still outstanding, when do you expect to receive the permit? A13: WETA expects to have a final ACOE permit for the project secured by spring Q14: RFP Reference: Team Qualifications, Experience, , 18 References, , Environmental Awareness, , Safety Plan. The RFP requirements listed above require Offerors to collect and submit with its proposal information for all Major Participants [as defined in the RFP significant subcontractors include glazing, exterior metal panel cladding, fuel system supplier, float supplier, soil mixing (ground improvements), soldier pile wall bulkhead, mechanical, electrical and lighting systems, marine construction, and landscaping]. Is it WETA s intent to evaluate and score an Offerors technical proposal based on the information contained for all of these rated factors to include significant subcontractors? This appears to be overly cumbersome to the evaluation scoring process as we anticipate the following potential submissions will be included with our proposal based on these requirements. It will also be very challenging to meet the page restriction requirements, where applicable, to comply with the requirements. Factor A Technical Approach 15 points No concerns noted. Factor B Team Qualifications 20 points Key Personnel Resumes (no page limit): Potentially 30 or more resumes to be evaluated for Offeror and Major Participants/Significant Subcontractors. Factor C Experience/References/Financial Capacity 10 points CENTRAL BAY OPERATIONS AND MAINTENANCE FACILITY Addendum No Page 3 of 8

4 Experience (8 pages max): Potentially 45 or more total projects listed (min 3, max 5 for Offeror, min 2 for each major participant, up to 14 significant subcontractors listed in requirements. References (no page limit): Potentially 25 references or more for Offeror and Major Participants. Factor D Environmental Awareness/Safety 5 points Environmental Awareness (3 pages max) RFP states to list any environmental citations received or other history for Offeror Major Participants and equity members of Offeror. As written, this potentially requires citation history to be collected from up to 17 or more Major Participants. Please confirm reach back period for citation history are required to be listed, and is environmental citation history included in the 3-page count. It states it should be 1 page or less. Safety Plan (2 pages max): RFP states to include copies of OSHA form 300A for the last 5 years for Offeror and Major Participants. This could potentially require up to 17 or more major participants to include 5 years of OSHA 300A logs. Does WETA want to see OSHA 300a records for all major participants including those listed as significant subcontractors as outlined in Team Qualifications. A14: WETA s goal is to assess the qualifications of the Offeror s subcontractors, in addition to the Offeror s qualifications as part of the evaluation process for each Technical Proposal received. The term Major Participant has been revised by this Addendum No. 1 to apply only to Subcontractors with a proposed subcontract value greater than 15% of the anticipated Contract value in order to streamline the proposal preparation process. See Section D of this Addendum No. 1 for more details. WETA has deleted the page limit for the Environmental Awareness section of Technical Proposals. The reach back period for citation history is 10 years. See Section D of this Addendum No. 1 for more details. Required Safety Plan submittals shall be provided for the Offeror, Major Participants and equity members of the Offeror. Major Participants shall include subcontractors with a proposed subcontract value greater than 15% of the anticipated Contract value, as set forth by this Addendum No. 1. Q15: RFP Reference: , 18. The RFP requires Reference Forms be sent to the POCs of the Offeror s and Major Participant s past clients. In the event that we have a past performance evaluation on file, and such evaluation is substantially the same as Document Reference Form (i.e. evaluation factors include quality, cost, effectiveness of management, safety) will WETA accept these existing evaluations in lieu of Reference Form B? Existing evaluations would include the POCs current contact information so as to allow the WETA to contact the POC to verify the evaluation. A15: Yes, provided that previous performance evaluations are substantially similar in form to WETA s Reference Form and were completed within the past two (2) years from the release date of this RFP. See Section D of this Addendum No. 1 for more details. Q16: RFP Reference: : DBE/SBE form documents DBE/SBE Subcontractor/Supplier Report-Document DBE/SBE Subcontractor/Supplier Selection Process Document SBE Affidavit of Size Document Would WETA allow Offerors to submit the DBE/SBE paperwork in the Price Proposal, rather than the Technical Proposal? Since the technical proposal is submitted first, it is assumed that Contractors will continue to work on their price proposal after the technical submittal has been submitted. For example a Contractor will not be able to answer columns 9 and 10 on form , page 2, until their price proposal is completed just prior to submittal. Additionally many smaller subcontractors may still be submitting sub-quotes to General Contractors for consideration. This will allow more time for DBE/SBE subcontractors to be incorporated into the project. CENTRAL BAY OPERATIONS AND MAINTENANCE FACILITY Addendum No Page 4 of 8

5 A16: Offeror shall submit the required DBE/SBE forms and shall provide the information requested to answer columns 9 and 10 on Document to the extent that information is available upon submittal of Technical Proposals to WETA. WETA may require that revised and complete DBE/SBE forms be submitted with Price Proposals. Q17: Does WETA prefer to have a single entity propose on the Alameda terminal or would you rather have a joint-venture that separates land & water work? A17: WETA does not have a preference for team structure as it pertains to Joint Ventures or other alternative arrangements. WETA s focus is on the qualifications of the team assembled and that team s proposed technical approach and management plan, in addition to other scoring criteria for the technical proposals. Q18: Would you please make available the digital/electronic CPT data files? Langan Treadwell Rollo should have those files. A18: Yes, the requested files have been posted online and are available for download at Please note, all data files are provided as reference material only. The Design-Builder assumes responsibility for the accuracy of the data or to perform their own testing. Q19: Is the mandatory presents at the pre-proposal conference intended to assure a Prime Contract Offeror participates? A19: Yes. Q20: Is it acceptable for a team member that is not a Prime Contract Offeror meet the mandatory participation requirement? A20: No. Q21: To further clarify question #2, is it acceptable for a design professional member to create a team with a Prime Contractor that was not present at the pre-proposal conference.
