A senior project manager will coordinate the work with the Client representatives, remediation contractor and <br /> industrial hygiene staff.The scope of work is based on 8-hour working shifts.Specifically,Omega will perform the following: <br /> • Conduct perimeter air sampling during removal activities at locations immediately outside the work area to determine how well asbestos <br /> fibers are being contained in the worksite.Omega will analyze collected area air samples onsite using phase-contrast microscopy(PCM), <br /> National Institute for Occupational Safety and Health(NIOSH)Method 7400. <br /> • Observe the work practices and procedures of the abatement contractor during asbestos related activities and monitor conformance with the <br /> applicable regulatory guidelines. Complete daily checklists summarizing field observations and will include these in a final written report. <br /> • Visually inspect the work area for remaining asbestos debris prior to the contractor's dismantling of containment barriers. <br /> • Collect clearance air samples prior to the contractor's dismantling of work area enclosures.Clearance air samples will be collected within the <br /> work area and analyzed onsite-using phase-contrast microscopy(PCM), National Institute for Occupational Safety and Health(NIOSH) <br /> Method 7400:and provide clearance sheet;and <br /> • Advise Client when analysis of clearance air samples indicates airborne fiber concentrations are within specified limits, so the asbestos <br /> contractor can dismantle the work area enclosures at that time. <br /> • At the completion of air monitoring a report will be submitted with a project summary,methodologies, recommendations and analytical <br /> results, <br /> Cost Estimate <br /> Limited Asbestos Assessments/Air Monitoring and Project Oversi ht/Re ort Development $35,000 <br /> Total Not-to-Exceed Estimate $35,000 <br /> Note:Assumptions/Exclusions <br /> ►Client to provide access to work areas at agreed upon times. <br /> ►The number of Project Manager and Monitoring hours is an estimate.Additional hours will be billed on a time and material basis if more hours <br /> than estimated are required.A shift is defined as a regular eight-hour Monday through Friday.Any hours worked over eight hours in a day will <br /> be considered overtime and charged at 1.5 times the applicable rate.Project Manager Rate$150 per hour and Field Tech$85 per hour.(see <br /> attached fee schedule) <br /> ►Additional hours worked over eight hours in a regular workday or weekend will be charged at$127.50 per hour for field tech.(see attached fee <br /> schedule) <br /> ►This price excludes supplies and expenses.(see attached fee schedule) <br /> General Terms and Conditions(Attached) <br /> Please Sign Below for Approval <br /> Signature Title Date <br /> Los Angeles ' San Diego • San Francisco 0 Seattle 0 Denver 0 Las Vegas • Phoenix 0 Raleigh <br />
