Site/Civil Program: SWPPP measures will be utilized to comply with Oregon DEQ policies. Existing paving not impacted by development will remain and be protected. Existing pool deck to be demolished and replaced with new concrete paving, graded to drainage structures, extending from edge of new pool drainagesystem to boundaryof work as shown on the attachedexhibit. Existing fencingnot impacted by development will remain and be protected. New fencing will be installed around the inside of the perimeter of the new concrete paving. New fencing will match existing black vinyl finish of existing fencing. Existing irrigation not impacted by development will remain and be protected. Existing irrigation components disturbed during development will be repaired to original condition. New irrigation components shall match the existing system. Non- contaminated topsoil shall be stockpiled and re-used for landscaping. Any new required top soil to be obtainedfrom local sourcesor those havingsimilar characteristics. Any new landscapesod shall be per specifications. Any existing trees will remain and be protected during construction. Any new landscaping shall meet specified requirements. Existing water utilities are present at the project site and are anticipated to have existing service connections. Existing sanitary sewer utilities are present on site and are anticipated to have existing service connections. Existing storm drain infrastructure not impacted by development and functioning properly shall remain and be protected. Previous connections to storm drain from demolished natatorium portion of the building shall be connected to proposed storm drain inlets andstructures. Building & Structure: Demolition of enclosing structure of the existingnatatorium and select portions of existing walls to create an outdoor pool facility and connecting breezeway through the existing building. Additional structure to be added where penetrations through existing masonry walls occurs at new breezeway. To be installed at walls that become exterior as a result of demolition: continuous insulation, air barrier, flashing, cladding system. Replace existing doors, frames, and storefrontat walls that become exterior. Extend new 4” concrete footingsto frost depth at walls that become exterior. Existing men’s locker room and fixtures shall be re-configured into two family changing rooms with showers and toilets, two individual changing rooms with showers, two unisex restrooms, and one chemical storage room. Building Systems: All existing dehumidification systems to be removed. Remove existing underground ductwork at natatorium perimeter. The existing non-pool areas are conditioned by an air handler (SAU-2) located in the existing mechanical room and will be re-utilized and modified to the greatestextent possible to accommodate the new space configurations and requirements. Where certain areas cannot be properly served by the existing SAU-2, supplemental HVAC system will be installed to meet these specificrequirements. The new restrooms and changing rooms and shower rooms will be fully conditioned and ventilated in accordance with all applicable codes and standards. The
facility’s existing drainage system will be modified and extended to accommodate the new fixture count and fixture locations. All new piping systems shall be properly sloped to assure code compliance installation. All new drainage piping shall be PVC pipe, installed at ¼” per foot slope. The facility’s existing potable water piping system will be protected and re-utilized to the fullest extent possible. The new fixture layout will require certain areas of the existing piping to be removed and new, larger pipe be installed in order to provide proper flow. All new piping shall be PEX. The existing domestic water heaters will be removed and new, high efficiency water heaters will be installed. The new hot water heatersystem will be sized to accommodate the new hot water demand of the facility. The new hot water system will also incorporate a new hot water return piping system and controls. The new return system will be designed in accordance with all new code requirements. The existing plumbingfixtures will be cleaned and re-used as possible. All new fixtures shall be commercial grade china fixtures with motion activated sensor faucets and valves. All new fixtures shall be specified and installed in accordance with ADA requirements. The plumbing system will be modified in order to provide proper support connections to the existing and new pool water treatment equipment/systems. The existing main electrical distribution gear appears to be nearing the end of the recommended life cycle for similar equipment. The intent is to replace the gear as part of the building modifications. Modifications are anticipated to include the main motor control center, the 480- Volt to 208Y/120-Volt step down transformers and the branch electrical panels. Where possible, the existing electrical wiring associated with the existing electrical distribution system will be maintained. New electrical devices will be provided throughout the facility as needed to accommodate the building configuration. New electrical connections will be routed to the new pool and HVAC equipment and all other electrical equipment loads. The design will include the replacement of the interior and exterior building lighting with new light fixtures utilizing LED technology. The lighting systems will be designed to provide lighting levels consistent with the Illuminating Engineering Society (IES) recommendations. The new lighting will be configured to accommodate the building and pool area modifications. Where applicable, the design will include maintaining the electrical conduit and wiring serving the existing lighting. The new lighting is anticipated to include2x4 flat panelLED fixtures in areas with laying ceilinggrid, surface mounted, flat panel LED light fixtures in areas with hard ceilings and damp location listed light fixtures in the shower areas. It is anticipated that 6-inch, LED, down lights will also be included in some areas of the building. The new lighting systems will include emergency egress lighting and exit signage as requiredby local life safety codes.Exterior lighting will include wall mounted LED fixtures with “full cut-off” light distribution to reduce glare and light trespass beyond the facility property lines. It is anticipated that the existing pole mounted lighting in the splash pad area will be maintained. The new exteriorlighting design will include exterioremergency egress lightingas required by local life safety codes. New automatedlighting controls meetingthe local energycode requirements will be designed for both the interior and exterior lighting. These controls are anticipated to include occupancy sensors in offices and storage areas and a programmable lighting control panel with integral astronomical time clock for control of interior lighting in areas open to the public and the exterior lighting. New manual lighting controls will be design as required by the local energy code and where the ability to control the lighting manuallywill be beneficial to the use of the space. The manual lightingcontrols will be design to provide ON/OFFcontrol as well as dimmingcontrol where applicable. It is anticipated that the design will include the removal and/or replacement of all existing data cablingthroughout the facility. The design will include data outlets and cabling in the Control area and data outlets and cabling as needed to establish wireless access coverage throughout the facility. The design will also includenew data cablingto all security camera locations identified by the owner. Aquatic Systems & Structures: Demolition and renovation scope adjacent to pool vessels shall require equipment that produces a load of 100 psf or more to maintain a distance from the edge of the pool vessel equivalent to the depth of the pool. Repair and infill of cracks in and spalling of concrete pool vessel. Repair joints with new filler material. Remove existing paint and re-finish vessels with aggregate plaster. Existing tile to be removed and replaced at pool edge and water line. Replace depth markers. Remove and replace existing perimeter gratings.
