×1.5 SAME-WORKS ESTIMATE GAP
Case 05 / One-building apartment, Shinjuku, Tokyo

Switching management to a structure with no construction-cost markup

Same works, ≈1.5× when routed via a manager

  • Doubts about suppressing PM/BM fees and recovering through construction costs
  • NOCOS never becomes the prime contractor: actual-cost pass-through plus competitive bids
  • Fee is a pre-agreed referral fee only — structurally no incentive to inflate works
  • After works, our staff run a pre-move-in check (reported by video)
→ Construction-cost transparency was the deciding factor; management switched
