COLUMNS (2 structural, cannot move) — PNG-VERIFIED
COL-WEST (Interior Column — Labeled 60x50 in Reference PNG)
| Property | Value | Notes |
|---|
| Size (E-W x N-S) | 60 x 50 cm | PNG reference dimensions |
| Center (zone coords) | (3.64, 1.36) m | = (364, 136) cm from SW |
| West face X | 3.34 m (334 cm) | from SW |
| East face X | 3.94 m (394 cm) | from SW |
| South face Y | 1.11 m (111 cm) | from south wall |
| North face Y | 1.61 m (161 cm) | from south wall |
COL-EAST (Partially Embedded in East Wall)
| Property | Value | Notes |
|---|
| Size (E-W x N-S) | 60 x 55 cm | 5 cm deeper than COL-WEST |
| Center (zone coords) | (7.57, 1.33) m | = (757, 133) cm from SW |
| West face X | 7.27 m (727 cm) | from SW |
| East face X | 7.87 m (787 cm) | 50 cm past east wall (737), ~10 cm visible |
| South face Y | 1.06 m (106 cm) | 5 cm further south than COL-WEST |
| North face Y | 1.61 m (161 cm) | ALIGNED with COL-WEST |
Column Span Summary
| Span | Distance | Notes |
|---|
| COL-WEST east face to COL-EAST west face | 333 cm | Clear span between columns |
| COL-EAST east face to east wall | 50 cm past | Partially embedded (~10 cm visible inside room) |
| Column north faces to north wall | 270 cm | Both columns aligned |
| Center-to-center | 393 cm | Between column centers |
- Both columns: north faces aligned at Y=1.61m
- COL-EAST extends 5 cm further south than COL-WEST (55cm vs 50cm depth)
- Build around without rigid coupling (isolate with neoprene/air gap)
DAIKIN VRF INDOOR UNITS (from HVAC DXF)
Unit Inside/Near Zone
| Unit | Position in Zone | X (m from SW) | Y (m from S) | Confidence |
|---|
| U380 | Near SE corner | ~6.88 | ~0.50 | APPROXIMATE |
Units Outside Zone (adjacent areas)
| Unit | Where | Distance from Zone |
|---|
| U370/U371 (paired) | East of zone (B302 area?) | ~2.7 m east of east wall |
| U328 | Far east (different B3 section) | ~10+ m east |
Air Devices (Diffusers)
| # | Inside Zone? | Position |
|---|
| 1 | YES (barely) | ~1.73m E, near south wall |
| 2-6 | NO | 0.9 to 4.6m WEST of zone |
WALL TYPES (for construction planning)
| Wall | Type | What to Do |
|---|
| North | Concrete exterior (30cm thick) | KEEP — build isolation wall inside with air gap |
| NW diagonal | Concrete exterior | KEEP — build isolation wall inside with air gap |
| East | 10cm gypsum to Server Room B313 | DEMOLISH old, build STC 58-68 wall (server noise: 55-65 dBA) |
| South | Interior partition | DEMOLISH, rebuild as acoustic partition |
- B313 gap: 10 cm between B3 east wall and server room
DXF COORDINATE MAPPING
For cross-referencing with AutoCAD:
Zone origin (SW) = DXF (-67.326, -144.217) meters
Transform: zone_x_cm = (dxf_x + 67.326) x 100
zone_y_cm = (dxf_y + 144.217) x 100
Key DXF reference points:
North wall inner face: y = -139.911 m (30cm concrete)
East wall partition: x = -59.956 m (gypsum to B313)
South wall: y = -144.217 m
