Amendment 1 PSA with Brown and Caldwell for Port Gardner Storage Facility Project <br />Exhibit A Scope of Work <br />14 <br />Task Assumptions <br />• No occupied spaces or lavatory facilities are included at the Effluent Pump Station or Lift Station <br />46. <br />• No landscape architectural services are included. <br />• Guardrails for process facilities will be similar to existing and do not require architectural <br />treatments. <br />• No screening walls will be required, including at the odor control facilities. <br />Everett Responsibilities <br />• None. <br />Meetings <br />• The project architect will attend six (6) Design Team/City design coordination meetings and two <br />(2) formal design review workshops with City. <br />• The project architect will attend two (2) meetings with City officials during building permit <br />application process. <br />Work Products <br />• Updated Architectural Design Guide with Code Review. <br />• Architectural Intermediate (60%) Design. <br />• Architectural Final (90%) Design. <br />• Architectural Bid Docs (100%) Design. <br />• Responses to City review comments. <br />Task 412 – Geotechnical (HWA) <br />Objective: Provide geotechnical engineering services to inform the PGSF intermediate and final <br />design. These services include additional site investigations and borings, updates to the <br />geotechnical data and engineering reports, and supporting development of project specifications. <br />The following section is a summary of the geotechnical design scope of work. <br />Activities/Approach: This task includes the following activities during design: <br />• Up to 3 Borings and site investigations to determine the soil properties and subsurface <br />characteristic at Lift Station 46 (Area 46), the Effluent Pump Station (Area 60), and standby <br />generator location. <br />• Utility locate services for additional borings. <br />• Geotechnical Exploration Work Plan. <br />• Install a data logging transducer to record water levels (at LS46 location) and monitoring for 1 <br />year. <br />• Based on HWA encountering suspect contaminated soils during previous investigations at this <br />site, the geotechnical borings will also include chemical sampling to dispose of investigation <br />derived waste (IDW) from drilling activities. One soil sample and one reconnaissance <br />groundwater sample, from temporary wells installed during drilling, will be collected per boring <br />and submitted to an environmental analytical laboratory for analysis of potential contaminants of <br />concern (PCOC) based on general disposal facility requirements for properties within an <br />industrial area. The laboratory will analyze up to 6 each soil and/or groundwater samples for the <br />following PCOC. Note that methods and analyses will differ by soil and water substrates: <br />
