The Contractor shall: 1. Visit and review the Site with the Engineer; 2. Prepare and provide the Engineer with a Soil Excavation and Disposal Plan, Groundwater Management Plan, Site Safety & Health Plan, and any other submittals required in this specification; 3. Obtain and comply with all necessary permits to complete the work; 4. Conduct startup including mobilization of labor, equipment, and materials; 5. Conduct pre-survey of excavation boundaries; 6. Provide and maintain temporary facilities and controls including temporary utilities (electricity/water), sanitary facilities, construction facilities, traffic controls, site and excavation security (e.g. barricades, temporary fencing); 7. Abide by the air monitoring plan and health and safety protocol; 8. Conduct public and private utility locates; 9. Provide erosion controls and stormwater controls; 10. Provide and install plastic sheeting to any non-impacted soil stockpiled; 11. Determine haul truck traffic patterns, setup loading station(s) and stockpile location(s); 12. Setup stockpile locations, if necessary; 13. Install shoring or other engineered controls (at Contractors’ discretion where shoring is necessary to achieve excavation depths and meet all applicable regulations); 14. Remove any permanent fencing in the excavation area that impedes completion of excavation activities; 15. Remove asphalt (both sides of former commercial building), concrete and gravel surfaces and remove remaining building slab and foundations; 16. Dispose of asphalt, concrete, gravel, and building slab and foundations; 17. Excavate soil within designated limits and to designated depths. Note: Excavation will largely be GPS guided excavation work given the limitations for field screening of arsenic and the comprehensive 3D modeling data available for the plume extent. Soils will be excavated utilizing existing plume map boundaries including the segregation of clean versus impacted soils. 18. Seal and abandon extraction well lateral piping in place per the Minnesota well code;
