A building is the most complex temporary organization most industries ever\nassemble: dozens of trades, thousands of materials, hundreds of decisions a day,\nall converging on a fixed site under weather, regulation, and a budget that was\nset before anyone knew what the ground hid. Construction management exists to make\nthat chaos finish — on time, on budget, safely, and to the drawings — by sequencing\nthe work, coordinating the trades, controlling the money, and absorbing the\nendless surprises without letting them cascade. The construction manager is the\nsingle throat to choke between an owner's intent and a finished, safe, occupiable\nstructure. Without them, every project is a collision of independent\nsubcontractors each optimizing their own scope while the whole drifts late, over,\nand dangerous.

The\n walk-around and the stand-down come before the milestone.\n- **Sequence is everything.** You can't drywall before rough-in, can't pour before\n inspection.

The defining relationships are the ones at the handoffs — between\ndesign and field, and between one trade and the next — where the CM's coordination\nturns independent scopes into a coherent build. Friction is constant and\nstructural: every party optimizes its own cost and schedule, and the CM's job is\nto align them to the whole, holding subs to scope while keeping the owner's trust\nthrough changes and surprises.
