Site Preparation: Making Room for the Building

3 min readWritten lesson

Week one of construction: demolition, clearing, grading, and utility trenches — plus the access and protection decisions that shape the whole build.

Week one is when the project stops being paperwork. It's also when several Module 2 and Module 6 topics stop being theoretical. Here's what happens and what to watch.

Demolition and clearing. The old shed, the concrete patio, the overgrown corner — everything in the building's footprint (and the utility paths') goes. This is where those hauling and dumping fees from lesson 6.8 get real. Anything you want saved — the mature lemon tree, the good pavers, the fence panels coming off for access — must be flagged before demo day, in writing, on the site plan. Demo crews are thorough by nature.

Protected trees get their fencing now. If your feasibility work flagged protected trees (lesson 2.5), their root zones get physical protection fencing before equipment arrives — often a city requirement with real fines behind it.

Grading. The pad gets cut and shaped to the plan's elevations — establishing drainage away from both the new building and the neighbors (Public Works' interest from lesson 10.6). On sloped lots this stage is bigger: cut, fill, possibly retaining work, and the soils report's recommendations (lesson 9.6) governing compaction.

Utility trenches open. The runs you routed in Module 7 get dug — often while the yard is already torn up, since trenching and grading share equipment. Smart sequencing note: everything that belongs in a trench (power, water, that conduit for the future — lesson 7.5) goes in now; reopening a trench later is paying twice.

Access and protection decisions. How do materials and machines reach the back? Which fence section comes down, whose driveway gets tracked, where does the dumpster live for six months, where do trades park? A five-minute conversation with your GC now — and a heads-up to the affected neighbors (lesson 5.8's goodwill, cashed in) — prevents months of friction. The site gets its temporary facilities too: power, water, sanitation, the porta-potty from lesson 6.8's list.

What can surprise here: buried mysteries. Old foundations under the lawn, abandoned septic tanks, undocumented pipes, soil that doesn't match assumptions. This is contingency's first test (lesson 6.9 told you it gets spent early) — and change-order discipline's first test too (lesson 11.9).

Key takeaways

  • Flag everything to save in writing before demo day — crews are thorough by nature.
  • Grading sets drainage for both homes; slopes bring the soils report to life.
  • Fill every open trench with everything it will ever need — reopening is paying twice.
  • Buried surprises live here: it's why contingency spends early, via signed change orders.
