At least 24 hours' advance notice is <br /> requested for our services during an on-call basis. During mass excavation,installation and <br /> testing of the tiebacks,and installation of the pile foundation elements,we will have a <br /> representative on site,full-time. Our services for the remaining tasks will be either part-time or <br /> on-call, as required by the construction schedule. <br /> After each site visit, our field representative will prepare daily field activity reports of observed <br /> construction activities and tests. Copies of our reports will be sent electronically to the City of <br /> Everett,The General Contractor,and RMI. Please let us know if additional circulation copies <br /> are required. <br /> While at the project site,our field representative will advise the City and Contractor of our <br /> observations and opinions. Recommendations that may affect the contract costs will be made to <br /> the owner. Our field representative will not instruct or direct the Contractor,as his direction <br /> should be received from the owner or others responsible for contract administration. We will <br /> contact you directly if immediate action needs to be taken. Our duties do not include a review of <br /> or responsibility for the adequacy of safety measures at or near the project site. <br /> Environmental Screening <br /> Based on the laboratory analytical results and field observations of the soil samples collected at <br /> the site along the proposed utility corridor,the majority of the soil appears to not be <br /> contaminated. However,soil represented by one of the composite samples,GP-1-7.5C,is <br /> impacted by heavy oil-range hydrocarbons. At a minimum,we recommend that environmental <br /> screening of the excavated material occur near the location of boring GP-1.
