BIMIO Opes

Openings for level B1

Services crossing this level's walls, floors and roofs, grouped into proposed openings and judged by the structural rule book. Nothing below was cut without explicit approval, and everything that could not be processed is listed with its reason — a host silently skipped is the one thing this report must never do.

MarkSizeServicesFindings
P01-MEC-019 490 x 290 mm Pipe 110 #413002, Pipe 75 #413009
  • This host is flagged as a shear wall or core. An opening here changes how the building resists lateral load and needs the engineer's sign-off.
  • Could not check: the model did not supply a distance to the nearest support.
  • 1 of 2 services had no readable insulation. If they are insulated, this opening is undersized by twice the thickness — and nothing else would tell you. measured 1 services, limit 0 services
  • The host is rated EI120, so this opening needs a sealing system stated on it.
P01-MEC-020 690 x 450 mm Duct 400x250 #412031
  • This host is flagged as a shear wall or core. An opening here changes how the building resists lateral load and needs the engineer's sign-off.
  • Too close to another opening on the same host. The material between two openings is what carries the load. measured 105 mm, limit 925 mm
  • Could not check: the model did not supply a distance to the nearest support.
  • Duct 400x250 #412031 crosses at 35° to the face, so the opening is 1.23x its nominal section. Sized from the projection, not the section. measured 1.2 x section, limit 1 x section
  • The host is rated EI120, so this opening needs a sealing system stated on it.
P01-MEC-021 925 x 450 mm Duct 300x250 #412044, Duct 250x200 #412057
  • This host is flagged as a shear wall or core. An opening here changes how the building resists lateral load and needs the engineer's sign-off.
  • Larger than the biggest opening allowed without a specific structural calculation. measured 925 mm, limit 900 mm
  • Too close to another opening on the same host. The material between two openings is what carries the load. measured 105 mm, limit 925 mm
  • Could not check: the model did not supply a distance to the nearest support.
  • The host is rated EI120, so this opening needs a sealing system stated on it.
P01-MEC-022 340 x 340 mm Pipe 160 #413044
  • This host is flagged as a shear wall or core. An opening here changes how the building resists lateral load and needs the engineer's sign-off.
  • Could not check: the model did not supply a distance to the nearest support.
  • The host is rated EI120, so this opening needs a sealing system stated on it.

Excluded hosts

3

Hosts Opes could not work on, each with its reason. These are findings, not noise.

HostReason
Walls id 884902 (Curtain Wall - Atrium Screen)Curtain wall — cannot host a face-based cutting family.
Walls id 885140 (Stacked Wall - Lift Lobby)Stacked wall — a multi-element composition, out of scope for v1.
Floors id 902580 (Slab - RC 200)The host's solid geometry could not be read, so nothing could be tested against it.

Blocked by ownership

1

Someone else has these checked out. Opes never takes ownership (it would write into the central file) — ask the owner to relinquish and run again.

HostReason
Walls id 884955 (Core Wall - RC 250)Owned by m.oduya. Opes does not take ownership — ask them to relinquish.

Sealed openings that drifted

8

The sync pass compared every sealed opening against the model as it is now. Stale means its host or services changed since it was cut; orphaned means they are gone; a locked opening is never updated — its discrepancy is an RFI, not an edit.

HostReason
P01-MEC-004its services' geometry changed since it was cut
P01-MEC-012its host's geometry changed since it was cut
P01-ELE-002a service it was cut for no longer exists in its link
P01-MEC-009its host and its services changed since it was cut — but it is LOCKED (built on site): raise an RFI, Opes will not touch it
P01-MEC-015a link is unloaded (or a ref unreadable) — whether this opening is still right could NOT be checked. Load the links and sync again.
P01-MEC-016a link is unloaded (or a ref unreadable) — whether this opening is still right could NOT be checked. Load the links and sync again.
P01-ELE-004a link is unloaded (or a ref unreadable) — whether this opening is still right could NOT be checked. Load the links and sync again.
P01-MEC-002everything matches again (was Stale) — recovered
