Port Gardner Storage Facility Volume 7 Attachment O <br /> Page 2 <br />CITY OF EVERETT ⋅ 3200 Cedar Street ⋅ Everett, WA 98201 ⋅ (425) 257-8800 ⋅ Fax (425) 257-8882 <br /> <br />Q5 - Would you be open to a discussion about how ground freezing could benefit this <br />project? We’d also like to explore whether a modification to the approach in the bid <br />documents—specifically around the dewatering scope—might allow us to offer a <br />comprehensive, competitive package that helps reduce risk and deliver greater value to <br />both the City of Everett and the contractors involved. <br />The current contract structure is designed for risk mitigation and cost <br />management. No changes will be made to the bid form or payment item <br />descriptions regarding the classification of dewatering activities as a Force <br />Account bid item. The City declines the opportunity to meet to discuss the <br />proposed benefits of the ground freezing technology. However, the contractor <br />has the option of providing value engineering solutions. Refer to Section 00 72 00 <br />General Conditions, Section 6.4. <br />Q6 - Specification section 46 21 13 1.05.A.30 outlines that the SI [Systems Integrator] is <br />to provide site specific UDT’s for bar screen programming. Please confirm this is <br />accurate. <br />Use of UDT's is the preferred approach to facilitate data exchange over Modbus <br />TCP/IP. If an alternative approach is preferred by the bar screen vendor, identify <br />this as a deviation during the submittal review process. This can be coordinated <br />with the systems integrator at that time. <br />Q7 - Section 46 21 13 2.08.F.8 outlines E-Stop push buttons, both local and remote. <br />Are there additional local E-Stop push buttons required for the bar screens, that are not <br />included in SCS-PB-20-LCS-0102 / -0202? If so, confirm the number of additional local <br />E-Stop push buttons that should be provided for each bar screen. <br />No exceptions taken to utilizing (1) HydroRanger 200 and (2) transducers for each <br />bar screen in lieu of dedicated transmitters for each transducer. Identify this as a <br />deviation during the submittal review process. <br />Q8 - Section 40 67 00 2.20.A outlines spare parts. Please confirm if the bar screen <br />vendor is required to provide spare parts per this section. <br />Spare parts for bar screen vendor shall be per Section 46 21 13 Paragraph 2.08.I. <br />Section 40 67 00 Paragraph 2.20.A Spare Parts does not apply to bar screen <br />vendor. <br />Q9 - Please confirm that ABB Electrical Equipment would be an acceptable “or Equal” <br />to the electrical equipment manufacturers listed within the specifications. <br />See Section 01 25 00 1.6.B.3 for non-proprietary product selection procedures. <br />Electrical equipment candidate manufacturers named within the specifications <br />reflect the candidate manufacturers the City has standardized against for their <br />facilities to reduce maintenance complexity and manage spare parts inventory. <br />These named candidate manufacturers, including those with no equal, served as <br />the basis of design for this project. Any other submitted manufacturers to be
