DocuSign Envelope ID: AFOFC7DF- FDAD- 4E58- A786- 72F744EA8560 June 22, 2018 ECS Southeast, LLP Utility Clearance We will contact North Carolina One Call to locate underground utilities at the site; however, our experience indicates that North Carolina One Call will not locate utilities beyond the point of distribution (meters or gauge points) on private property. We will coordinate our test boring /pit locations in order to avoid any underground utilities indicated by the North Carolina One Call locating system. Due to the developed nature of the site and to facilitate safety, a private utility locating service is proposed for this project. Our lump sum fee includes the cost for ECS to retain a private locator service to locate utilities beyond the meters and public utilities at the site. ECS will also coordinate with the Owner, utility companies, and municipalities concerning the location of underground utilities within the planned work areas. Contracting a private utility locator service is not a guarantee that all utilities within a work site will be identified, but a service that is offered to lower the risk of the owner /client. ECS and our clients have had past success in avoiding utility conflicts by augmenting the North Carolina One Call services with a private utility locator service. Private utility locator services can identify utility alignments that incorporate significant iron content in the conduit materials. However, private utilities possessing the higher likelihood of not being easily identifiable, beyond the point of distribution, include all utilities not containing significant ferrous (iron) content (examples would include but not be limited to most sanitary sewer alignments, copper or PVC water lines, fiber optic lines without tracer ribbons, copper electric lines with no surface exposure, drainage tiles /pipes, and irrigation lines). Where a private locator service identifies a potential risk that is not traceable through conventional methods, ECS will notify the client immediately and work to resolve the issue. Additional costs related to the resolution of these potential utility conflicts will be invoiced out per our unit rates, as identified in this proposal, or as negotiated and approved at the time of the occurrence. Site Restoration Upon completion of subsurface exploration drilling, we will backfill each of the boreholes with the drill cuttings and mound the excess spoil back up over the test. In pavement areas, we will patch the asphalt surface with a cold mix asphalt patch of an equivalent or greater thickness of asphalt. Typically, we will not provide site restoration beyond what is outlined above unless specifically contracted to do so. Alternatively, we can remove excess spoils from job sites and dispose of them in an approved manner for a negotiated additional fee. Please note that some disturbance to off - pavement surface areas, including the possible rutting of lawns, cutting of trees, running over of brush and understory in wooded areas might occur. We will attempt to minimize such disturbance; however, we have not budgeted for site restoration of the site including filling of tire ruts, seeding of lawn areas, or the planting of trees. If necessary, additional site restoration can be provided at an additional cost. ECS Proposal No: 06:20895 Page 14 9i V
