Project overview

Innovation at Tideway

To deliver a World Class asset, collaborative thinking and product lifecycle lies at the heart of innovation investment decisions.

Tideways’ mature supply chain understands how to engage with innovative clients to deliver value - Delivers UK government ‘Construction 2025’ industry vision.

Tideways’ Innovation vision

The Thames Tideway Tunnel is recognised as the ‘game changer’ in terms of Innovation on [UK] projects.

Tideways’ Legacy Strategy States

A clear Innovation strategy will help release the potential of this historic, essential endeavour, not just for the river and all the people who use it, for work or pleasure, but for the environment in general, for London more broadly and for the country as a whole.

BIM at Tideway

“Level 2 BIM maturity is a series of domain and collaborative federated models, consisting of both 3D geometrical and non-graphical data, prepared by different parties during the project life-cycle within the context of a common data environment. The project participants provide defined, validated outputs via digital data transactions using proprietary information exchanges between various systems in a structured and reusable form.”

BIM at Tideway

The requirement for the Main Works Contractors for BIM is embedded within the Works Information provided at the Invitation to Tender phase. It is rooted in and derived from industry standards and OPEN formats such as IFC and COBie.

It includes requirements for:

• BIM Execution Planning (BEP)

• Information standards and data exchanges

• Collaboration, Coordination and Compliance

And critically:

• Asset Data standards and deliverables

BIM targets To provide an Asset Information Model (AIM) that will be used during project construction and then upon project completion to catalogue features built and aid in the management, operation and maintenance of the system to control CSO discharges to the tidal Thames.

This will be achieved by procuring Project Information Models (PIM) from our Contractors progressively developed during the works and submitted at critical decision points: Employers submission gates for detail design, for construction, as constructed and takeover.

The connumdrum

• Dealing with an asset management process that deals with the large and the small but in many cases with nothing in between

• The need to test and confirm the OPEN BIM approach and specific technical requirements provided to Main Works Tenderers

• Embedded processes and resources focused on the traditional delivery of the Development Consent Order (DCO) and the Main Works Tenders

• A requirement to provide a level 2 BIM data drop of its reference design to its key stakeholder Thames Water, in order to initiate and complete their estimation and asset management processes

• But as a project the team had to ensure value for the project stakeholders and minimise spend and budget creep related to developing technology which the project may or may not require at a later date

What we had - Graphical Information

Data or information conveyed by geometry, with or without associated properties, spatially coordinated to represent and enable physical interaction with, or analysis of, an asset.

• Parametric modelling of the each site to enable drawing production

• Semi intelligent 3D objects based on parts and families but focused on construction materials rather than function

• Integrated with other model forms such as laser survey point clouds

What we had - Non-graphical Information

Data or information conveyed as values only, with or without associated properties but still potentially spatially coordinated, to represent and enable the query or analysis of an asset.

What we had - Documentation Information for use in the briefing, design, construction operation, maintenance or decommissioning of a construction project, managed within a common data environment based upon a BS1192 collaborative process.

What we had – a knowledgeable and flexible vendor

Long standing mutually beneficial relationship between ch2m and Bentley Systems. The project benefiting from the availability of the enterprise license agreement enabling the full use of the product range and the a long term technical working relationship with their professional consultancy services.

They already had a product that had 80% of the functionality but was aimed at the end of the Lifecycle.

Collaborative Learning The connection between people

Innovation definition “the successful commercial exploitation of new ideas. It includes, scientific, technological, organisational, financial, and business activities leading to the commercial introduction of a new (or improved) product or service”

(Dodgson, Gann and Salter, 2008: 2)

The solution

Asset structure

Based upon the projects understanding of how to describe its assets within an industry standard data model capable of providing data to TW’s O&M CMMS.

The chambers tag provides the information relationships required to ‘describe’ it and relate it to other components.

Non-graphical data captured using BS1192-4:2014 COBie standard data sheet with inherent relationships

Federate non-graphical data

Non-graphical asset information data store

Asset structure now available within the CDE

Apply non-graphical data to graphical data

The non-graphical information available within the modelling application

Assets linked to associated documentation

Generate IFC and iModel output (and the non-graphical using the same COBie tool)
