BIM Technology

BIM as its own technology: multi-discipline authoring, railway and transit models, clash-free coordination, 4D/5D time-cost, ISO 19650 common data environment, constructible structure, and as-built handover into the twin. Specified for CPWD, NHAI, Indian Railways station redevelopment, metro and RRTS EIRs.

Model Authoring

Architecture, structure, and MEP in one parametric model.

Code	Product	Primary use	Key spec	Open
NBIM	Multi-discipline BIM Authoring One parametric model for architecture, structure, and MEP — drawings, schedules, and quantities from the same source.	Station buildings	Disciplines: Architecture / structure / MEP	View

Railway & Transit BIM

Track, OLE, station, and signalling corridors.

Code	Product	Primary use	Key spec	Open
RT-BIM	Railway & Transit BIM Corridor, track, OLE, station, and signalling in one information model — for IR, metro, and RRTS.	IR station redevelopment	Scope: Track / OLE / station / signalling	View

Clash & Coordination

Federated models. Hard and soft clash. Close-out reports.

Code	Product	Primary use	Key spec	Open
N-CLASH	Clash Detection & Federated Coordination Federate every trade into one model. Find the clash in the hut, not on the possession.	Metro stations	Checks: Hard / soft / clearance	View

4D / 5D Planning

Programme and bill on the same objects.

Code	Product	Primary use	Key spec	Open
N-45	4D / 5D Time-Cost BIM The model linked to the programme and the bill — time as the fourth dimension, cost as the fifth.	EPC programmes	4D: Programme / WBS linked to objects	View

Common Data Environment

ISO 19650 CDE, BEP, and LOD packs for Indian public clients.

Code	Product	Primary use	Key spec	Open
N-CDE	ISO 19650 Common Data Environment The single source of truth for BIM tenders — BEP, containers, status, and LOD packs for CPWD, NHAI, IR, and metro.	CPWD works	Standard: ISO 19650-1/2/5	View

Constructible Structure

Steel and RC the shop can cut.

Code	Product	Primary use	Key spec	Open
N-FAB	Constructible Structural BIM Steel and reinforced-concrete models that a shop can cut, bend, and erect — not a design sketch.	Station roofs and concourses	Trades: Structural steel / RC	View

Twin Handover

As-built information model into the live twin.

Code	Product	Primary use	Key spec	Open
N-HANDOVER	BIM-to-Twin Handover The as-built information model becomes the digital twin the operator actually runs.	Station FM	Drop: COBie-style / classified IFC	View
