<br />Lake Orange – Intake Tower Servicing – Scope Description <br />The existing Lake Orange intake tower drain gate (48-inch wide steel sluice gate) and the associated <br />manually-operated top-slab mounted actuator are believed to be original to the initial construction of <br />Lake Orange in 1969. The existing sluice gate and actuator were fabricated by Rodney Hunt, Inc. <br />Currently, the existing sluice gate is very difficult to operate manually. An inspection conducted in <br />September 2018 revealed the presence of sediment and/or corrosion within the gate tracks and <br />around the gate seating surface. On-site de-mucking of the intake tower interior and servicing of the <br />intake tower drain gate and actuator are required so as to free up the intake tower drain gate and <br />improve ease of operation. <br />Scope Description: <br />No utility location is required. No permitting is required. This work shall be conducted using OSHA <br />confined space procedures and will require the support of a standby rescue team. The standby <br />rescue team will be coordinated and provided by Orange County. This project is located entirely <br />within Orange County property. The project site address is 1221 Lake Orange Road, Hillsborough, <br />NC 27278. There is currently no functioning power source on site. See Attachment B for the location <br />of the project. See Attachment C for site photographs of the proposed work area. <br />A. Provider shall supply all labor and materials for pressure-washing the interior concrete <br />walls and bottom slab of the intake tower. The associated sediment and/or runoff from the <br />pressure washing activities shall be completely flushed out of the intake tower via gravity <br />flow using the existing 48-inch concrete outlet pipe. The 100 linear feet of 48-inch outlet <br />pipe will also require flushing, which may be facilitated by opening the intake tower lake <br />gate. Provider shall coordinate this work in the field with Orange County staff. <br /> <br />B. Provider shall supply all labor and materials for servicing the existing intake tower drain <br />gate (48-inch sluice gate) and associated gate operating hardware so as to improve the <br />ease of manual operation, including but not limited to: <br /> <br />1) Pressure washing and/or manually cleaning and then lubricating the gate <br />tracks/wedges/guides; <br />2) Cleaning and readjusting the gate stem guides; <br />3) Lubricating the grease fittings on the existing gate actuator; <br />4) Cleaning and lubricating the upper stem/screw (above/inside the actuator); <br />5) Opening (and then properly re-sealing) the exterior case of the top-slab mounted gate <br />actuator to evaluate whether moisture is present inside the actuator, clean and <br />lubricate any/all accessible parts inside the actuator prior to re-sealing the exterior case; <br />6) Test operating all cleaned and lubricated hardware. <br /> <br />C. The work described above shall be completed in one day (8-hours) or less, so as to <br />minimize remobilization fees and the need for a standby rescue team. <br />Attachment A <br />DocuSign Envelope ID: 884B2CFE-2DE5-44E8-9F7A-8208DA7367FC
