Road areas (5,221 m²) in 20 m sections along the ring roads and the Igwali Street spur, 1.74 km of kerb measured once, stand lines, and the four survey benchmarks with an indicative ground plane. No services or ground levels are placed; the supplied survey and sewer sheets cannot yield them. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
