He had resisted upgrading for months. His old 32-bit setup crashed whenever he tried to process more than 8,000 alignment points. But after a catastrophic blue screen the previous week, his IT manager, a sharp-eyed woman named Helena, had forced the switch.

“Trust me,” she had said, installing the 64-bit build from a USB drive labeled CivilCAD_2016_x64_Final . “More memory. Less tears.”

Near sector 7 of the survey, a series of points formed a perfect arc—not natural terrain. He zoomed in. The coordinates suggested an abandoned concrete foundation, undocumented in the original geotechnical report. If he built the drainage channel over it without mitigation, the structure could crack within two years.
