A combination of the Brief and the Scope developed for use by the Contributors. The strategy provides a basis for achieving the Client’s objectives in a consistent and structured manner.

Building Information Modelling (BIM)

Design Lead

The Participant’s representative who is responsible for the day-to-day design and is responsible for validating their Model Scope. This individual must understand their fee, resourcing, design responsibility and the Reliant Use(s) of their Models. The relevant Design Lead will need to be present at the Issue Resolution Workshops.

Element

A system, assembly, component or zone which fulfils a function of the construction entity.

Element Class

Defines whether an Element is a system, assembly, component.

The Elements required to be modelled in the Contributor's Models

General Arrangement Review

An interdisciplinary comparison between GA Elements and the corresponding Placeholders in terms of geometry, location and orientation.

A software to support Issue Management, allowing for the tracking and reporting of issue priority, status and allocation.

Issue Resolution Workshop

A collaborative session covering issues resulting from analysis where the priority, status and allocation of issues are discussed and set.

Level of Detail (LOD)

Defines the representation of the three dimensional geometry of an Element. (The LOD does not imply a Data Scope to be attributed to the Element. Reliant Use(s) of a Model cannot be inferred from the LOD of its Elements.)
D1 – Represents the volumetric extent of the Element

D2 – Represents all the external surfaces of the Element
D3 – Represents all the external and internal surfaces of the Element

Level of Granularity (LOG)

Defines the number of sub-elements representing the parent Element Class. (When applying a LOG to an element it only relates to the generation immediately preceding or following its tier.)
G1 – Represents the Element as a single entity
G2 – Represents the Elements that need to be inspected, maintained and/or replaced individually within the parent Element by the Operations Manager.
G3 – Represents all the Elements that are required to assemble the parent Element

Licence

A permit to use a Model(s) for a particular Reliant Use(s) or Non-reliant Use(s).

Location & Orientation

Outlines where the physical location of the project is transposed to in model space and specifies the orientation.

Logistics Analysis

A process to identify and simulate, in space and time, the particular order, path and movement of Elements.

Manager

The Participant on the project who is responsible for the leadership, execution and delivery of the BIM process.

Master Volumetric Scope

All the zones that make up the volumetric totality of the project.

Model

The three-dimensional geometry and attribute data representing a Contributor's Model Scope.

Model Audit

A self-contained, one-off analysis performed to measure compliance with requirements and/or to gauge Model Fidelity.

Model Fidelity

The degree of exactness with which Elements are modelled with regards to their intended interface, location and orientation. (Level of Detail (LOD) is irrelevant)

Model Lead

The Participant’s representative who is modelling on the project and is responsible for the Model Fidelity of a particular Model Scope. This individual must anticipate the time required to implement change. The relevant Model Lead will need to be present at the Issue Resolution Workshops. (This is not to be confused with the organisation's BIM advisor.)

Model Scope

Outlines where and what the Contributors are modelling and consists of Volumetric Scope, Element Scope and Data Scope. (Model Scopes are developed specifically for their Reliant Use(s).

Modelling Obligations

Contributors will concurrently develop the design and Model as an iterative process.
Contributors will ensure that any Element within a Model which is illustrated on drawings will be derived from the Model.
Contributors will ensure Model Fidelity.
Contributors will ensure that the attribute data applied to Elements is correct.

Nomenclature Analysis

A process to check if the required data attributes are populated with the correct nomenclature as specified in the Contributors’ data directories. (Nomenclature Analysis does not validate whether the content of the attribute fields are correct.)

Non-reliant Use

Any use for a Model Scope other than the Reliant Use(s); for which the model author is not held liable.

Participant

A Beneficiary, Contributor or Manager partaking in the BIM process.

Placeholder

A temporary representation of an Element by a Placeholder Author that will be superseded in time by the Primary Author's Element.

Placeholder Author

A Contributor who is responsible for the modelling of a Placeholder Element until superseded by the Primary Author's Element.

Primary Author

A Contributor who is responsible for the creation and validity of an Element’s geometry and data as defined in the Model Scope.

Reliant Use

A use for which a Model Scope is specifically developed and validated, and for which the model author is liable. (Models are developed in the most efficient way for their Reliant Uses which may not be suitable for other uses of the Model).

Strategy Obligations

All Participants are to appoint a Design Lead and a Model Lead as key points of contact. (Notify GRFN if these individuals change)
Design Leads and a Model Leads will be available for the development of the BIM Scope.
The BIM Scope will be defined with an understanding of the time and resource implications of the Modelling Obligations and Analysis Obligations.

Volumetric Scope

An agreed three-dimensional zone(s) representing the modelling extent of a Contributor's Model.

Volumetric Extent

An agreed three-dimensional zone communicating the modelling extent of a Contributor’s Model.

Volumetric Strategy

An agreed assembly of three-dimensional zones clearly communicating different locations of the project for focus.

Introduction

GRFN is a data-driven Management Consulting firm specialising in data analytics and information management for the construction industry. The focus of our work is to help clients mitigate risk and drive productivity through people, process and technology.

Services

Strategy

Strategy is integral to achieving any objective and should address technology, process and people. Implementation needs to incorporate analysis, education and management, whether at organisational level or project level. We strive for optimum granularity to allow us to align, and therefore identify, the limiting factors to our clients achieving their goals.

Analysis

Advocating a systematically ruthless approach, we bring structure, always reassessing the critical path and highlighting issues to the Project Team. Utilising agile processes to analyse both geometry and data, we present a transparent understanding of the state of the project, providing a foundation for informed decisions.

Management

With the success of the project at the forefront of our minds we bring substantial value through our people skills, knowledge and experience. We strive to be facilitators, instrumental in accelerating the fusion of people and process, while guiding the team to overcome impediments to project delivery.

Education

The aptitude and willingness of the Project Team is key. We want to convert the willing into the able, recognising that people’s abilities to be flexible and to collaborate are intrinsic to the success of a project. Through education, the mindsets of a team are aligned and the project vision brought into focus.
