Motor will have a quick connect weatherproof plug for removal from the controller without unwiring the unit. In addition, install a quick connect plug for the existing grinder motor. Specification included in bid package. Controller and grinder will rotate usage with the other grinder already installed. Paint wet well # on each grinder (bright color red on side or top of motor housing, minimum 4 inch letters). This grinder rotation will be done automatically under the manual switch. When the operator manually rotates the pumps the grinder will automatically operate under that manual switch over, when rotating from pump # 1 to pump # 2 and vice versa. Rewire existing # 1 grinder to operate when # 1 pump is scheduled to operate. The wiring will be from the existing motor controller housing. Gut old motor controller to power grinder controller. If existing conduit and wiring will not work, then install new conduit and wire per code. Label the motor control box with the device it controls and power source. Mount the new motor controller inside the building on the wall when you first walk in to the left. Same wall as window. Location to be reviewed in mandatory Pre-Bid Conference. Move the existing motor controller next to the new controller. Put controller # 1 and # 2 on the front of the box. Supply and install all power needed for this work. Provide power from the grinder to the controllers (in schedule 80 PVC conduit) through the building wall along the middle handrail protecting the wet well to the walk path grate. Install a flex conduit from the junction box at the handrail to the grinder motor. This is where the disconnect weather plug will be. The male weather proof plug will be on a small pigtail off the motor. 3. Supply and install three new check valves designed for this application. Minimum AWWA C-508 standard, swing check bolted bonnet to match original design. Pump # 1 from wet well # 1. Pump # 2 from wet well # 2. Back up pump from wet well # 1.

Pump parts must be available from many suppliers and not be a one-source vendor. Pump power and controls will be installed in the old existing motor controller housing. Gut old motor controls from housing. Label motor controller (power, pump feed location and etc). Page 3 of 6

4 Operation of pumps Pump # 1 (large pump) will operate when the manual old motor controller is turned on. This will power pump # 1 and grinder # 1. This is wet well # 1. Pump # 2 (large pump) will operate when the manual old motor controller is turned on and pump # 1 is turned off. This will power pump # 2 and grinder # 2. This is wet well # 2 There is no interlock in the operation. Pump # 3 (small pump) is a backup pump. It will pull from wet well # 1. It will be on a separate power location in the existing old motor controller. Each pump will have a disconnect (with pump # painted on it minimum 3 inch letters color red). If pump one needs service then it can be disconnected from the service as power will still be available for grinder # 1, or grinder # 2 if needed. Pumps will have the motor directly on the top of the pump. If a new power feed is required for the pumps then the contractor is responsible, turnkey operation. Remove old pumps, shafts and motors in the building. Turn equipment over to the facility. Install a ¼ inch galvanized plate with galvanized angle to cover and sit down in the holes. Removable if needed. 6. Add a second backup sump pump (minimum 1 hp) and piping (with check valve) with float switch for removing water from the basement. Water is discharged to the outside wet well. 7. Supply and install a new auto dialer at the lift station. Sensaphone Express II LIT 6700 or equal, specification included in bid package. The auto dialer will notify the NEFSH 24-hour control room if there is an issue at the lift station. (Issues such as pump will not shut off, pump will not come on, grinder not operating, building under generator power, sump pump is running, etc.). It will also call the NEFSH Maintenance Superintendent and the City of Mcclenny Wastewater Treatment Plant. If there is no answer, the auto dialer must have the ability to call three (3) other contacts, in continuous rotating order until someone answers. Mounted location will be in an old location at the existing motor controller or on the left wall between the windows when you first walk into the building, Location to be reviewed in the mandatory Pre-Bid Conference. 8. Basement exhaust fan, Replace the roof exhaust fan that removes air from the basement. New fan will match the original design specifications for the building. Review original drawings or what is installed. Information for the fan is in the bid specifications. If the conduit, power or disconnect is not current or operating for this fan replacement, then the contractor needs to replace all Page 4 of 6

5 that is needed to make the fan operational, which could include bringing up to current code. (Color is white if the fan has a cover or needs painting. Use metal paint specification if needed or provide galvanized cover). 9. Install new floats (if the existing floats are not usable or operating or there is not enough floats) in each wet well to operate the pumps. There will be four (4) floats in each wet well. Indicated low level and high level for an alarm. Low level to turn the pump off, high level to turn the pump on. This will be sitting on 316 stainless steel hooks (mounted on a 316 stainless steel flat bar minimum 3 inches wide and 4 foot long an 3/16 inches thick) on the side or back of the wet well. Hooks have locks where the float cable cannot be knocked off. Provide sufficient room to dip out trash from the wet wells. 10. Between wet wells., raise the valve handle (to the top of the handrail) that operates the cross over valve between the wet well # 1 and # 2. Paint handle and all metal except greased screw (Color is sewer). Lubricate existing parts for smooth operation. 11. At wet well with bar screen, raise the valve handle (two each) to the top of the handrail. The valve handle operates the valves that allows water flow from the bar screen wet well to wet well # 1 and wet well # 2. Paint handle and all metal except greased screw (Color is sewer green). Lubricate existing parts for smooth operation. 12. Add a 1200 lumens LED floor light to each corner of the building with a switch for night work. These will shine towards the bar screen and wet wells. Mount under soffit of building. Power can be surface mounted. Light switch will be inside of door next to existing light switch. Make galvanized conduit look neat and finished. Alternates Included in Bid Specifications: Alternate # 1. The building is sinking and separating in the middle. Contractor will hire a subcontractor that specializes in foundation stabilization. The building will be shored up with auger piles and install spray foam to fill the void under the building if needed. This will keep the building from sinking in the future. DCF has current boring sample and compaction information of soils. Alternate # 2. The contractor will hire a roofer to install a new roof on the building. Roof will be white in color 60-mill membrane TPO or PVC. This is based on the Carlisle SynTec Systems. The membrane is Sure Weld Fleese BACK that is a minumn 115 TPO. The roof will come with a 20yr warranty. Roof expansion joint will be replaced or repaired with warranty. Page 5 of 6

6 Alternate # 3. Lift and re-set two valve boxes where the boxes are sinking and the lids are resting on the valves. They are outside of the building, between the building and the gate. Alternate # 4. Have an engineer design a boom with an electric winch. This will be used for the removal of trash in the bar screen. Have a basket designed that will be lowered in the wet well for trash collection and removal. Trash will be dumped into 55 gallon drums or steel trash containers. The boom will also be able to remove the grinder shaft and motor for maintenance or replacement. All power and controls are by the contractor. Basket will be 316 ss mesh. Return grassy area around site to original condition before construction. 1. Contractor will maintain a clean site on a daily basis. Area beyond construction site operations are not to be disturbed. Site constraints will be coordinated with Northeast Florida State Hospital maintenance staff on a map before commence of work. Lay down site will be designated at the pre-bid meeting. We will also determine if the site needs fencing. 2. Keep driveways and entrances clear at all times. Do not use these areas for parking or storage of materials. Schedule deliveries to the site, to minimize the storage of large amount of materials. 3. Existing facility operations will continue during construction. Some of the work will be supervised, by Northeast Florida State Hospital staff or security staff, due to security issues and or location of the work. Coordination issues will be addressed and worked out in the preconstruction phase. 4. Full Owner Occupancy: The Owner will occupy the building, site and adjacent buildings during construction. Cooperate with the Owner to minimize conflicts and facilitate Owner usage. Perform the work so as not to interfere with Owner s operations. 5. Use of Site: Maintain the site and repair damage caused by construction operations. Take necessary precautions to protect the existing buildings and occupants during the construction period. All material will be secure at all times to protect, contractor, staff and clients wondering the campus. Contractor will not interact will clients any any time. Any question to contracted staff, about any and all work being performed, will get the response as follows: Contact Scott Sharp at Maintenance. END OF SECTION Page 6 of 6
