Building Information Modeling (BIM)

O3 delivers comprehensive BIM solutions for our clients.  We have experience of working on many BIM projects.  BIM offers a great opportunity and challenge to the construction community, with the potential benefits such as:

– Increased efficiency

– Improved coordination

– Greater predictability

– Reduced risk

– Better quality

– Enhance safety

– Reduced construction time and costs

– Enhanced potential for Facilities management (FM)


The construction industry is currently undergoing the biggest digital revolution, since the shift from drawing boards to computer aided design (CAD) known as BIM.  BIM or Building Information Modelling is a process for creating and managing information on a construction project across the project lifecycle.  This is most often associated with Autodesk Revit Software as the design platform.  However, BIM is more than a design tool.  It is a methodology and a new way of working, which gives benefits to all stakeholders.  These benefits apply not just during the construction of the project but may continue throughout the life of a building.

At nCLO3URE we recognize the advantages of this new approach, which can provide:

– Better collaboration and communication of the design team.

– Improved coordination and clash detection of the multi-discipline design.

– Model-based cost estimation.

– Preconstruction project visualization.

– Reduced cost and mitigated risk.

– Improved scheduling and construction sequencing.

– Increased productivity and pre-fabrication.

– Safer construction sites.

– More effective servicing and maintenance throughout a building’s lifecycle.

BIM Strategy and Application

nCLO3URE currently delivers projects utilizing both AutoCAD and Revit software platforms.  AutoCAD is used for certain projects where not all key members of the design team are committed to delivery using Revit based building information modeling (BIM).  For Quality Assurance to be carried out efficiently and effectively the following requirements shall be implemented for all technical deliverables:

– Client requirements and relevant standards are fully understood, and information supplied is appropriate for use (Client critical interaction).

– Technical services are carried out by competent people using effective processes and tools.

– Quality Assurance is an integral part of the project.

– Quality Assurance roles are defined and communicated.

– Change, risk and information flow are managed (Client critical interaction).

– Errors identified are corrected and deliverables are reviewed to ensure client’s requirements have been satisfied (client critical interaction).

– Lessons learned are captured and communicated and the effectiveness of quality assurance is monitored.

BIM is created by nCLO3URE using Autodesk Revit software. Design models are constructed using defined templates and populated with the data defining objects and their attributes.  Conventional two-dimensional outputs can be extracted in the form of plans, sections, elevations, and details, as well as 3D views, images and walk-throughs.

Models are developed as part of the design process with the level of development (LOD) in line with the system of design work stages adopted by nCLO3URE – Concept Design LOD 100, Schematic Design LOD 200, Detail Design Development LOD 300, System drawings LOD 350, Shop drawings LOD 400, Clash detection LOD 450 and as-built drawings LOD 500.

nCLO3URE‘s BIM Policy

nCLO3URE’s BIM policy is to design and deliver full-service commissions with BIM where the members of the project design team are aligned in intent and capability. The objectives of this policy are:

– To improve the quality of the design and engineering process as BIM provides the designer with a simulation of the design intent or object.

– To facilitate co-ordination between the various disciplines contributing design inputs to the project.

– To provide, where required, the base for subsequent transactions including the development of detail for procurement, construction activities, and operation and maintenance.

Where nCLO3URE is appointed as the provider for design and engineering on a project, the implementation of BIM on the project is part the appointment process, and our professional service offer to clients, unless there is a specific requirement not to do so.  Where we are appointed to undertake limited services up to and including systems design, the development of a model in BIM may not be technically or commercially appropriate, and other software may be sufficient for the objectives of the appointment.

Model Definition

The LOD (Level of Detail) to be achieved at each work stage is defined below:

– Concept Design: LOD 100 is a conceptual model, where parameters like area, height, volume, location and orientation are defined.

– Schematic Design: LOD 200 is a general model, where elements are modelled with approximate quantities, size, shape, location, and orientation.  Non-geometric information can be attached to the model elements.

– Detail Design: LOD 300 is an accurate model with drawings where elements are defined with specific assemblies, precise quantity, size, shape, location, and orientation. Non-geometric information to the model elements can also be attached.

– Issue for Construction: LOD 350 Includes model and element detail that represent how building elements, interface with various systems   and   other   building elements with graphics and written definitions.

– Shop Drawings Model for construction: LOD 400 where model elements are modeled as specific assemblies, with complete fabrication, assembly, and detailing information in addition to precise quantity, size, shape, location, and orientation. Non-geometric information to the model elements can also be attached.

Clash Detection: LOD 450 is a model for facility management

– As Built: LOD 500 where elements are modelled as constructed assemblies for maintenance and operations. In addition to actual and accurate size, shape, location, quantity, and orientation, non-geometric information is attached to modeled elements.

Model Usage

nCLO3URE models are ‘design information Models’ and must be treated as such.  The design information models LOD 100, 200, 300, 350, 400, 450 and 500 are construction information models.

Where BIM is intended to be applied to the shop drawing production/construction phase of the project, it is the responsibility of nCLO3URE to develop ‘Construction information Models’ to an LOD suitable for the installation and full coordination of other trades and services.
