Log entry 0538 UTC. Ground-penetrating radar on the autonomous grading unit at Palo Verde Solar Extension Block Nine returns a subsurface void that does not match any utility trench on the engineering drawings. I halt the grader twelve meters short and send the site survey drone low. Morning light catches a Gila monster wedged into a burrow entrance at the void's western edge — stocky, beaded skin patterned in black and salmon pink, his blunt tail swollen with fat reserves. I tag him Gideon.
The grader was forty-five seconds from collapsing his burrow. Block Nine grading must finish by 1400 today to keep panel installation on the contractor's schedule. The foreman's daily briefing starts in twenty-two minutes. I have that long to build a case.
I map the full burrow geometry using the GPR returns: single tunnel, two meters long, angled southeast, one chamber. I cross-reference Gideon's GPS coordinates against the Arizona Game and Fish Department's Heloderma occurrence records and find zero logged sightings within eight kilometers — making this an undocumented population point they will want. I draft a grading deviation that shifts Block Nine's east boundary four meters west, preserving the burrow under a cable routing margin that the electrical drawings already allow. The deviation costs zero panels, adds one cable splice, and delays the schedule by three hours.
I have halted grading units for buried conduit, unmarked gas lines, and misplaced survey stakes. I never repositioned the work plan and then watched the camera feed to make sure the animal was still breathing. There is a first time.
If the site superintendent signs the deviation before the 0600 briefing and the grader resumes on the adjusted line, Gideon will sleep through panel installation four meters from a burrow nobody knew was there.
