Attachment 10 NE concrete walk removal.pdf

This is an instructional photograph documenting concrete sidewalk removal and replacement procedures. The image shows two contractors on a residential property demonstrating the scope of work required for a concrete remediation project. The photograph identifies five key work areas marked with colored arrows: removal of non-expanded aggregate concrete (red arrows), removal of concrete at the joint line (red arrows), location of the storm drain under the removed concrete (red annotation), patching sawcuts with matching concrete (magenta arrows), and retention of the existing walk section (red annotation indicating "walk to remain"). A sawcut is visible on the right side of the image, indicating the boundary between areas to be removed and areas to remain. The visual demonstrates the technical requirements for selective concrete removal while maintaining structural integrity of remaining portions and accounting for underground drainage infrastructure during the demolition and reconstruction process.
