Overview
This document defines the construction sequence for the MediaVerse Studio Complex. The 10 phases must be executed in strict order — each phase has prerequisites that depend on the previous phase being complete and signed off. Six of the ten phases are acoustically critical [AC] and require hold-point inspections [HP] before proceeding.

Phase 1: Preparation & Demolition
Phase 01 of 10
Preparation & Demolition
Prerequisites: Approved construction drawings (B301–B308), site access, safety plan, demolition permit if required.
Steps

QC Checklist
- Slab-to-slab height confirmed at 340 cm (±5mm)
- Zone perimeter dimensions match SSOT within ±25mm
