The striped pathway shall run continuously alongside the enclosure, passing in front of the double-leaf access gate. 5. At the north end of the generator enclosure, the contractor shall construct a second ADA-compliant concrete transition ramp to raise pedestrians from the asphalt elevation back up to the elevation of the existing sidewalk. This ramp shall tie into the existing sidewalk system and restore the pedestrian path around Building 644. This installation must follow construction details in Attachment 4, Detail 11 - Curb Ramp Type C. Part 3: Electrical Work - Extension and Relocation of Mobile Generator Tap Box 1. The contractor shall relocate the existing generator tab box approximately 35 feet to the new enclosure location. This box is currently run from an Automatic Transfer Switch (ATS) located inside Building 644, with conduit routed to the existing exterior tap box. Additional photos showing the existing conditions are shown in Attachment 5. 2. The contractor shall extend the existing conduit run along the same general path as the current installation. Minimal demolition of the existing conduit is anticipated, as the system will be extended rather than replaced. To facilitate the relocation, the contractor shall install new conduit through the masonry wall that the enclosure is built against, providing a weather-tight penetration sealed and finished to match the adjacent surfaces. 3. Conductors inside the conduit shall be replaced as required to achieve proper length, continuity, and performance for the extended conduit run. All conductor sizing, insulation rating, terminations, grounding, and labeling shall meet current VA, NEC, and project specification requirements. The relocated tap box shall be mounted within the enclosure at a height and orientation suitable for mobile generator connection and shall be fully tested for continuity and proper operation. Part 4: Sidewalk Corrections Around Building 651 1. Prior to beginning any construction work, the contractor shall perform a detailed topographic survey of all affected areas and submit layout drawings for review and approval by the COR. These drawings shall illustrate the proposed work, including but not limited to concrete limits and ramp configurations. Drawings shall indicate final grading and slope percentages. 2. The contractor shall perform all labor, material procurement, demolition, grading, and construction required to correct sidewalk deficiencies at the northeast corner of Building 651. Work includes removing unpaved dirt areas between existing concrete sidewalk panels, constructing new concrete pavements, and providing a side extension to the existing accessible ramp where the current ramp edge terminates at an unpaved area. A mockup for solicitation purposes and additional photos showing existing conditions are shown in Attachment 6. 3. Due to variations in elevation among the surrounding sidewalk panels, the contractor shall demolish and remove existing concrete slabs as needed to achieve compliant slopes and transitions. The extent of demolition shall be determined in the field in coordination with the VA COR to ensure ADA compliance and proper drainage. The contractor should expect to demolish up to 1000 SQFT of concrete in the area. 4. The contractor shall excavate, compact, and prepare the subgrade within the affected areas in accordance with VA specifications. Subgrade elevations shall be established to allow new concrete sidewalk panels to tie into adjacent surfaces smoothly while meeting all ADA slope requirements. 5. The contractor shall install new concrete sidewalk panels to fill the existing unpaved areas and replace any removed concrete. New sidewalk shall match existing sidewalk appearance and alignment. All concrete shall be installed per VA specifications for materials, reinforcement, expansion joints, finishes, curing, and quality control. 6. The contractor shall ensure the entire ramp assembly transitions seamlessly into the newly constructed concrete surfaces. This installation must follow construction details in Attachment 4, Detail 10 - Curb Ramp Type B. The contractor shall ensure all newly constructed sidewalks, ramp extensions, and transitions meet ADA requirements for running slope, cross slope, and surface characteristics. 7. Grading shall provide positive drainage away from building foundations and prevent ponding along the pedestrian path. 8. The contractor shall restore all areas disturbed during construction, including adjacent soil, landscaping, or pavements. The contractor shall maintain safe pedestrian access around the work site throughout construction. A final inspection shall be conducted with the VA to confirm that all sidewalk corrections meet project drawings, and VA technical specifications. 9. The contractor shall relocate the existing STOP sign and the NO RIGHT TURN sign to the opposite side of the street, positioned ahead of the crosswalk. Sign shall be reinstalled at VA-approved locations that provide clear visibility and proper traffic control for approaching vehicles.
