Modifications or substitutions to the specified equipment or layout must be approved by the engineer. 2. The contractor should inspect the site prior to submitting an estimate to the owner. Any potential conflicts should be reported to the engineer. By submitting an estimate the contractor indicates that he has investigated the site and has found no discrepancies with the plans and specifications. 3. A preconstruction conference is mandatory before starting installation of the system. Contact engineer to discuss important aspects of installation. The engineer will not certify the system at the final inspection unless a preconstruction conference is done prior to installation. 4. A final inspection is required — The installation must pass inspection by the engineer. Notify the engineer of the planned inspection date in advance. Prior to final inspection the contractor should shoot all invert elevations and take as -built triangulation measurements. The contractor shall provide as -built measurements to all components of system to the engineer at the final inspection. The OWNER is responsible for paying the engineer's inspection fees. 5. If adverse subsurface conditions are encountered (rock, groundwater, utilities, etc.) contact the engineer. 6. If site conditions vary contact the engineer. 7. The contractor is responsible for maintaining all set back distances as required by local ordinances and health department and payment for all inspections by health department. 8. Installation shall be in accordance with Virginia Department of Health Sewage Handling and Disposal regulations and in accordance with erosion and sediment control guidelines. 9. A separate Project Manual contains calculations, equipment cut sheets, etc. A separate package contains AOSE soil information. 10. Notify "MISS Utility" prior to excavation. Gravity Sewer/Effluent Main/Force Main 1. Gravity sewer from the office to the sewage ejector tank is 4" SCH 40 PVC sewer. Cleanouts every 50'. 2. Effluent mains shall be 4" schedule 40 PVC and have a slope of 6" per 100' minimum. 3. Force main and pressure piping shall be 2" Schedule 40 PVC. L 1 H OF`� � 2 o M CHAEL F. CRAUN LICEN E NO.
