What this means when you scope a building

  • Missouri and Illinois sites are best scheduled as separate routes, since bridge crossings add time to every visit.
  • With 40 hospitals in the region, many medical suites sit in ordinary office buildings. Exam rooms get their own task list, apart from the admin space around them.
  • Manufacturing employs 110,031 people across the metro, and plants need production-floor scrubbing and locker-room care on a shift schedule.
  • Winter salt and freeze-thaw cycles are hard on lobby floors. Plan extra entry mopping and a spring scrub.
