Building Information Modelling (BIM) has moved from industry buzzword to mandatory requirement in major construction markets worldwide. In the UK, BIM Level 2 has been required on all centrally-procured government projects since 2016. Dubai mandates BIM for large projects under DCD guidelines. Australian and Canadian government clients increasingly require BIM Execution Plans as part of their project briefs.
But beyond compliance, BIM delivers genuine value on every project - reducing clashes, improving coordination, enabling better cost control, and creating a digital asset that serves the building throughout its life.
At Nexbase Engineering Inc., we are equipped to deliver BIM files across all engineering disciplines - Architectural, Structural, Plumbing and Electrical - in Revit and IFC formats.
What BIM Actually Delivers on a Construction Project
BIM is not just a 3D model. A properly implemented BIM model contains geometric information, material properties, component specifications, quantities, spatial relationships, and metadata - all linked and coordinated across disciplines.
Clash Detection & Coordination
The single biggest source of value from BIM on complex projects. When structural, architectural, and MEP models are federated into a single coordinated model and run through clash detection software (we use Autodesk Navisworks), conflicts that would previously have been discovered on site - at maximum cost - are identified and resolved at the design stage.
Typical clashes caught in BIM coordination include: HVAC ducts running through structural beams, plumbing pipes clashing with column reinforcement, electrical cable trays insufficient clearance from sprinkler pipes, and architectural ceiling heights conflicting with mechanical equipment.
Accurate Quantity Takeoff
Quantities of structural concrete, reinforcement steel, ductwork, pipework, and cabling can be extracted directly from the BIM model. This reduces estimation error and enables faster, more accurate cost planning - particularly valuable at the early stages of a project when scope changes are still possible without major cost impact.
4D Construction Sequencing
Linking the BIM model to the construction programme enables 4D simulation - a visual representation of how the building will be constructed over time. This helps contractors plan site logistics, identify sequencing conflicts, and communicate the construction plan to clients and stakeholders.
Facilities Management Asset Data
A well-structured BIM model delivered at project completion becomes the basis for Computer-Aided Facilities Management (CAFM). Equipment assets in the model can carry serial numbers, maintenance schedules, warranty information, and replacement cost data - forming the core of an intelligent building operations system.
Our BIM Deliverables
Architectural BIM File
The architectural model is the geometric backbone of the federated model. It contains all architectural elements - walls, slabs, roofs, curtain walls, stairs, openings, doors, windows - modelled with correct dimensions, materials, and spatial relationships. Delivered in Revit (.rvt) and IFC format for interoperability with all BIM platforms.
Structural BIM File
The structural model contains all structural elements - foundations, columns, beams, slabs, shear walls, bracing members - with section properties, reinforcement data, and connection node positions. Exported in Revit and IFC; can also be exported to Tekla Structures exchange format for steel fabrication.
Plumbing BIM File
The plumbing model includes all pipework systems - cold water, hot water, drainage and vent, fire suppression mains - with pipe diameters, fittings, valves, and equipment modelled in 3D and fully coordinated against structural and architectural elements.
Electrical BIM File
The electrical model includes cable trays, conduit routes, distribution boards, transformers, generators, and luminaire positions. Panel schedules and circuit routing are linked to the 3D geometry for coordination and quantity purposes.
BIM Standards by Market
UK - ISO 19650 / PAS 1192: The UK BIM framework requires a Common Data Environment (CDE), Employer's Information Requirements (EIR), and a BIM Execution Plan (BEP). Information containers must follow a standardised naming convention. We are familiar with these requirements and can deliver fully ISO 19650-compliant BIM packages.
USA - National BIM Standard (NBIMS-US): AIA Document G202 defines BIM Protocol. LOD specification published by BIMForum is the primary reference for USA projects. Revit is the dominant platform; IFC is used for interoperability.
Dubai / UAE: Dubai Municipality and DCD have issued BIM mandates for large buildings. The DM BIM Guidelines specify minimum LOD requirements and model submission procedures for permit applications. Coordination with Dubai's smart city CityGML initiatives is increasingly required for large master-plan developments.
Australia - NATSPEC BIM Guidelines: Several state governments including Queensland, Victoria and NSW mandate BIM on major government projects. ISO 19650 is being adopted progressively. Green Star rating tools interface directly with BIM models.

What software do you use for BIM?
We primarily use Autodesk Revit for all discipline modelling and Autodesk Navisworks for clash detection and 4D simulation. We deliver in native Revit (.rvt) and open IFC format, which works with ArchiCAD, Tekla, Allplan, and all other major BIM platforms.
Can you produce a BIM Execution Plan (BEP)?
Yes. We prepare BEPs that define roles, responsibilities, information exchanges, model structure, LOD requirements, and CDE procedures for the project - aligned to ISO 19650 or your client's own BIM Standards.
Do you provide BIM as a standalone service if we already have 2D drawings?
Yes. We can convert existing 2D CAD drawings into coordinated 3D BIM models for coordination, clash detection, quantity takeoff, and authority submission purposes.
Can you provide BIM models for LEED/BREEAM energy modelling?
Yes. We export BIM geometry to EnergyPlus, IES-VE, or DesignBuilder for energy simulation, and can produce the required documentation for LEED EA credits or BREEAM Energy category credits.
