Building Information Modelling (BIM) is a collaborative way of working underpinned by digital technologies. It uses a shared digital representation of an asset to facilitate design, construction and operation processes to form a reliable basis for decisions. Greater efficiencies can be realized due to significant pre-planning during the design and construction phases, providing comprehensive information at handover stage.

BIM guiding principles

BIM has introduced some new principles in how assets should be designed, built and operated in order to best realize the potential benefits offered by this new way of working.

People, processes and technology

BIM is not just about technology; it’s a new way of designing, constructing and managing assets enabled by the use of technology. Equally, if not more fundamental than technology is the set of processes that should be followed (outlined within the ISO 19650 and BS/PAS 1192 series of standards) as well as the change in working practices at an operations level. This is best exemplified by the need for a collaborative approach across the supply chain.

Collaborative engagement

One of the key success indicators of a project using BIM is the degree to which the supply chain has worked in collaboration to meet the project/asset needs. This means working openly as well as sharing information and experience with supply chain members in a way that encourages collective problem solving and coordination.

Start with the end in mind

A key problem that is addressed by using BIM is the issue of rushed decisions being made with insufficient and/or incorrect information. Starting with the end in mind, these decisions are pushed “up-stream” so that they are better informed and do not present themselves unexpectedly. Examples of this include; completing all principle design work and coordination before the commencement of construction, and ensuring that design decisions are being made across the entire delivery phase with respect to the operational performance and utilization of the asset (BS 8536).

Digital asset

It’s becoming increasingly recognized that monetary value is not solely attributed to the physical asset, but also attributed to the representation of that asset, in other words, the collective sum of all data/information describing the physical asset. Knowing that this digital asset accurately represents the physical asset; design, construction and operating decisions can be optimized.

Holistic approach to security

Once it has been identified what needs to be protected and the threats and consequences associated to this, (in order to ensure the security of a sensitive asset and sensitive information) a holistic approach should be adopted covering people, process, technological security and physical security.

Terms and abbreviations

There are many terms which form part of the BIM language. Whilst not exhaustive, here are some of the common ones to look out for.

CDE Common Data Environment

A workflow to control the single source of information for any given project or asset. Used to manage the collection and dissemination of all relevant approved project/asset information.

Used in combination with a digital storage solution, information is shared collaboratively in a logical and accessible way to help all key parties readily gain access to information, using consistent naming conventions, avoiding duplication and retaining ownership.

Status code

This is a meta-data field within the CDE workflow which is used to describe the suitability of the information to which the status code is assigned. The status code identifies the permitted use of the information and can be used to help facilitate specific workflows.

OIR Organization Information Requirements

This specifies what information is required to achieve an organization’s strategic objectives in relation to business operation, asset management, portfolio planning etc. The OIR may be developed from an ISO 55001 asset management system.

AIR Asset Information Requirements

This defines the information that is required, and the managerial and technical aspects of producing this information, for the operation of an asset.

EIR Exchange Information Requirements

This specifies the information that is required related to a specific appointment (contract). It includes responsibility, timescales, format and level of information need of the project information; consisting of the relevant information requirements from the OIRs, AIRs and PIRs.

PIR Project’s Information Requirements

This specifies the information that is required related to a specific project; consisting of the relevant information requirements from the OIRs and AIRs.

Level of information need

This is a methodology to specify the granularity of information to support a given purpose. This should be defined as the minimum granularity to avoid over- production of information leading to waste.

Project’s Information standard

This establishes requirements on the exchange of information, the structuring and classification of information, assignment of level of information need and use of information in the operational phase of the asset.

Project’s Information Production Methods and Procedures

This establishes the methods and procedures required to be used when generating, reviewing, distributing or delivering information.

BEP BIM Execution Plan

This specifies the delivery plan which will be undertaken by the delivery team as a response to the received tender documentation. It includes, amongst other things, who is responsible for providing information, as well as who will be undertaking which responsibilities within the delivery team.

Delivery team’s Mobilization Plan

This details the approach, timescales and responsibilities for the delivery team to be implemented during mobilization. This includes testing information exchanges between task teams and testing the proposed information production methods and procedures.

MIDP Master Information Delivery Plan

Developed from the BIM Execution plan, this is the primary plan for when information is going to be prepared, by whom and when. It also sets out the format and the timescales. Each information deliverable will be aligned to a defined project delivery milestone.

TIDP Task Information Delivery Plan

This is a plan, developed by each task team, which is incorporated into the Master Information Delivery Plan based on the agreed responsibilities outlined within the BIM Execution Plan.

Delivery Team’s Risk Register

This details the delivery team’s risk associated with the timely delivery of information deliverables in accordance with the EIR. Considered risks include (amongst others), meeting the information delivery milestones and adoption of the project’s information standard.

PIM Project Information Model

This is the aggregation of information developed during the design/construction phase of the project. Information that forms the PIM is created by the project team controlled by the CDE workflow. As the project develops so too will the PIM, which will increase in both size and accuracy; starting as a design intent progressing to a record of construction once complete.

COBie Construction Operation Building Information Exchange

This is a structured method of exchanging information about maintainable assets. COBie, often delivered as a spreadsheet, has a pre-defined structure that is used to share this information in both a human-readable and machine-interpretable manner.

AIM Asset Information Model

This is the aggregation of information needed to support the management and operation of the asset (infrastructure or building). The AIM is typically formed or updated using a subset of the PIM at the handover stage of a project. The AIM will continually be updated and developed as information is provided following works that affect the asset.

Global BIM adoption

Governments around the world have already or are starting to introduce different requirements to embed the adoption of BIM. In April 2016 the UK Government introduced a condition of contract requiring all Government commissioned construction projects to be delivered at ‘BIM Level 2’ competence. In Singapore it became mandatory in 2015 for all projects greater than 5000 Sqm. Germany has mandated construction of public infrastructure works to adopt with BIM processes from 2020 and Hong Kong has issued a number of circulars to foster the adoption of BIM technology in public works projects.

With the publication of ISO 19650, parts 1 and 2, BIM will now move to having an internationally agreed definition. ‘BIM according to ISO 19650’ defines the minimum requirements and gives further recommendations to applying best practice to BIM.
