Principles of Best Practice The production of co-ordinated design and construction information is a task- and time-based process, independent of which procurement route or form of contract is used. Each task needs to be carried out in a particular order for the mutual benefit of all those involved, otherwise known as ”collaborative working”. In a collaborative working environment, teams are asked to produce information using standardized processes and agreed standards and methods, to ensure the same form and quality, enabling information to be used and reused without change or interpretation. If an individual, office or team changes the process without agreement, it will hinder collaboration – a participant insisting on “my standard” is not acceptable in a collaborative working environment.

This approach does not require more work, as this information has always been required to be produced. However, true collaborative working requires mutual understanding and trust within the team and a deeper level of standardized process than has previously been experienced, if the information is to be produced and delivered in a consistent timely manner. The benefits of working in this way can include fewer delays and disputes within the team, better management of project risk and better understanding of where costs are being incurred.

Wherever possible, the principles of lean should also be applied to reduce the expenditure of resources for any goal other than the creation of value for the employer. For example, BS 1192:2007 promotes the avoidance of wasteful activities such as: • waiting and searching for information; • over-production of information with no defined use; • over-processing information, simply because the technology can; and • defects, caused by poor co-ordination across the graphical and non-graphical data set which require rework.

However, for the production of information to be truly lean, it is critical to understand its future use. This is achieved by “beginning with the end in mind” and identifying the downstream uses of information, to ensure information can be used and re-used throughout the project and life of the asset. It is to this end that PAS 1192-2 has been produced. It is anticipated that this document is of equal value to small practices as well as large multi-nationals. The impact of poor information management and waste is potentially equal on all projects. Where appropriate we have offered some advice as to how the process and methods described here can be implemented in a scalable fashion to suit all organizations.

Initial set up in a project

1. CDE – Common Data Environment a means of providing collaborative environment for sharing work

Advantages: • Access to the same information at the

same time • Control of collaborative processes

(ownership, time/cost) • Visibility of team performance • Single source of truth!
