12、ormats. The collected data are processed andtransferred throughout the supply chain to be used by a variety of people andorganizations.The management and delivery of these data needs to be defined andmaintained throughout each project, integrating the requirements set out in theproject specification

13、 together with the objectives of those who produce andthose who use the data. This can be achieved by the introduction of a datamanagement system based on an organizations data management policy, whichis covered in this standard.A data management system is applicable to geotechnical and environmenta

14、linvestigations, construction projects with activities such as piling, earthworks andtunnelling, monitoring and asset management.The procedures described in this standard facilitate the management ofgeotechnical data for use in a BIM project in accordance with PAS 1192.BRITISH STANDARD BS 8574:2014

21、4 13 Data management principles3.1 GeneralThe geotechnical data management principles given in 3.2 to 3.7 should beimplemented at the start of a project.NOTE Further details on each principle are given in Annex A.3.2 Data collectionData should be collected at source, entered once and retained electr

22、onically, e.g.in a computer system. New data should be checked against collected data toensure quality and compatibility. The time of the collection and transfer of datashould be stated in the data management plan (4.5).How and where the data are entered into the computer system should be statedin t

23、he data management plan.If it is not possible to log data electronically at the source of collection, the datashould be recorded manually in a paper-based format only once and thenentered into a computer system.3.3 Data storage3.3.1 GeneralData should be stored securely, backed-up and access careful

24、ly controlled.3.3.2 SecurityThe data store should have controlled access, be regularly backed-up and have adisaster recovery plan.The management of the store should define and incorporate user rights (i.e.writing, reading and editing). Data should be safeguarded from unauthorizedaccess.3.3.3 Version

25、 controlThere should be a record of additions and changes to the data and each revisionissued should be sequentially referenced and archived.3.3.4 ConsistencyWhere data are stored in multiple systems or locations, such as field collection,laboratory and engineering, it should be consistent.3.3.5 Sta

26、tusThe status of the data should be recorded (A.2.2.4).3.4 Data archiving, retention and disposalThe requirements for data archiving, retention and disposal should be identifiedand documented in the data management plan. Archived data should be storedto ensure long-term readability.NOTE Long-term re

27、adability might be achieved using non-proprietary or openstandard formats.3.5 Sharing and transferring dataTo ensure the availability and widest use of geotechnical data, the followingshould be taken into account:BRITISH STANDARDBS 8574:20142 The British Standards Institution 2014a) within the conte

28、xt of an organization: industry-standard exchange formatsshould be implemented;NOTE Details on industry-standard exchange formats are given in A.2.4.b) within the context of a project: strategies for data sharing and transfershould be agreed at the onset;c) delivery timescales should be agreed at th

29、e start of a project;d) the data receiver should be briefed on how the data have been evaluatedand for what purpose; ande) permission should be sought from the owner for the use of data by thirdparties, after an agreed confidentiality period.3.6 Unique referencing of dataTo avoid data duplication, e

30、ach record should be identifiable using a uniquereference.NOTE A unique reference can be a combination of attributes, e.g. location andsample depth and sample type or pile reference and test number.3.7 Data verification and validationThere should be repeatable methods of data verification and valida

31、tion that aretraceable and auditable.Data verification and validation should be performed at input and export ofdata into a computer system and as required by the data management plan.4 Data management system4.1 GeneralA data management policy should be implemented using a data managementsystem. The

32、 data management system should consist of a policy (4.2), strategy(4.3), manual (4.4) and plans (4.5).4.2 Data management policyAn organizations management should authorize a data management policy.The scope of the policy should be appropriate to the nature and scale of theorganization.The policy sh

33、ould be clear in its aims, scope and responsibilities, and shouldinclude a commitment to continual improvement in data management. Thepolicy should be reviewed on a regular basis and when significant changes occurin the organizations structure.The policy should be compatible with other organizationa

34、l policies, for examplequality and IT policies.NOTE The purpose of the policy is to provide a framework for managing data bysetting data management objectives within the organization.4.3 Data management strategyThe strategy should set out the goals and timescales of the organization andidentify the

35、types of resources (people, computer systems, software, etc.). Thestrategy should also define the key performance indicators (KPIs) and the criticalsuccess factors (CSFs).NOTE 1 KPIs are measureable targets that evaluate success against the strategicgoals.BRITISH STANDARD BS 8574:2014 The British St

36、andards Institution 2014 3NOTE 2 CSFs are elements required to deliver the strategy.4.4 Data management manual4.4.1 GeneralThe manual should record how the organization approaches the managementof geotechnical data. The “plan do check act” (PDCA) management method ofcontinual improvement given in 4.

39、, implement and maintain a datamanagement manual and commit to continually improve its effectiveness inaccordance with the recommendations of this standard.NOTE Individual projects might require a project-specific data managementmanual.4.4.2.2 Roles and responsibilitiesThe manual should show the org

40、anization structure of the data managementteam(s) and their roles and responsibilities.NOTE An organigram is a useful way of graphically representing the organization.4.4.2.3 Register of data management plansThe data management manual should contain a register of all datamanagement plans governed by

41、 the manual. The register should contain:a) data management plan reference;b) data management plan title;c) author details (person and date); andd) status.4.4.2.4 ReviewThe data manager should review the data management system to ensure itscontinuing suitability, adequacy and effectiveness.
