It was prepared by Technical Committee CB/5
7、00, Procurement. A list oforganizations represented on this committee can be obtained on request to itssecretary.Relationship with other publicationsThis British Standard is complementary to BS ISO 10845-1 and BS ISO 10845-21),which cover construction procurement in relation to processes, methods an
8、dprocedures, as well as the formatting and compilation of procurementdocumentation.NOTE There are other sources, see Annex A, that provide operational guidance.The remaining parts of the ISO 10845 series (Part 3 to Part 8) have not beenadopted as British Standards. If clients wish to use them they a
9、re encouraged tocheck their compliance with EU procurement law. European Standards for theprocurement of engineering consultancy services for building, infrastructure andindustrial units are in development.BS ISO 15686-5 deals with property life cycle costing and impacts on constructionprocurement,
10、notably on major investment and Private Finance Initiative (PFI)and Public-Private Partnership (PPP) projects. However, it also impacts on thedesign of new buildings through clients desire to set the right budgets andoptimize their life cycle costs from a whole-life value and sustainabledevelopment
11、perspective.BS 8903 gives guidance to organizations and individuals on how to consider andimplement sustainable practices within their procurement processes and ongoingmanagement of their respective supply chains.Information about this documentIn May 2006 a strategic workshop was held to establish w
12、hat drives value in theconstruction industry. It and a subsequent series of specialist workshops weresponsored by the then Department of Trade and Industry and its successor, theDepartment for Innovation, Universities and Skills, under the heading“Rethinking Standards in Construction” and organized
13、by BSI and ConstructingExcellence in the Built Environment. The main conclusion was that there wasdefinite potential for a new standard on procurement, provided it used theOffice of Government Commerce process (see Annex A) as a baseline.Users might find it useful to cite BS 8534 in any BS EN ISO 90
14、01 documentationand in their contracts. In this way, adoption of BS 8534 can be promoted.There are a number of sections in this British Standard where a distinction isdrawn between procurement by public sector bodies and other procurements(i.e. those by non-public sector bodies). It is important to
15、do so becauseprocurement by public sector bodies is governed by the Public ContractsRegulations 2006 (the Regulations) 1, which reflect EU Directives, see Annex B.The Regulations 1 apply to most procurements that have a value above thethresholds set out in the Regulations 1. In procurements to which
16、 theRegulations 1 apply, the procuring body takes a number of mandatory stepsand the effect of the Regulations 1 is to constrain the structure of theprocurement process. Best practice for a particular procurement in the privatesector not constrained by the Regulations 1 might be reflected by adoptin
17、g adifferent structure.1)BS ISO 10845-1 and BS ISO 10845-2 are in development.BRITISH STANDARDBS 8534:2011ii BSI 2011NOTE Attention is drawn to the legal and regulatory constraints of England anddevolved administrations, the rules of public procurement and any specificregulatory regimes that apply t
18、o the sectors the procurer is engaged in (e.g. energyor transportation).Use of this documentAs a code of practice, this British Standard takes the form of guidance andrecommendations. It should not be quoted as if it were a specification andparticular care should be taken to ensure that claims of co
19、mpliance are notmisleading.Any user claiming compliance with this British Standard is expected to be able tojustify any course of action that deviates from its recommendations.Presentational conventionsThe provisions in this standard are presented in roman (i.e. upright) type. Itsrecommendations are
20、 expressed in sentences in which the principal auxiliaryverb is “should”.Commentary, explanation and general informative material is presented insmaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis publication does not purport to include all the n
21、ecessary provisions of acontract. Users are responsible for its correct application.Compliance with a British Standard cannot confer immunity from legalobligations.BRITISH STANDARD BS 8534:2011 BSI 2011 iiiBRITISH STANDARDBS 8534:2011This page deliberately left blankiv BSI 20110 IntroductionIn procu
22、rement systems such as those used by the World Bank, the UnitedNations Commission on International Trade Law (UNCITRAL) and the EuropeanUnion, each category of procurement is dealt with separately with the provisionof its own implementation guidelines or regulations. ISO took the view that thiscompa
23、rtmentalized approach caused confusion and made procurementunnecessarily complex. Therefore, ISO 10845 (all parts) introduced an alternativeapproach of first developing a generic procurement system and then identifyingthe methods and procedures best suited to particular categories.The objective of t
24、he ISO 10845 series is to provide a generic and standard set ofprocesses, procedures and methods for a procurement system that is fair,equitable, transparent, competitive and cost effective. The standards apply topublic or private sector client organizations in the development of theirprocurement sy
25、stems and their principles are intended to apply down the supplychain. The main objective is the creation of a framework for the development ofprocurement systems that facilitate fair competition, reduce the possibilities ofabuse, improve predictability of outcome and allow the demonstration of best
26、value. In particular, ISO 10845: establishes basic requirements for the conduct of an organizationsprocurement, including integrity and the avoidance of conflicts of interest; creates a framework for the development of an organizations procurementpolicy; and describes generic methods and procedures
27、for procurement, including adetailed consideration of the alternatives available, including negotiation,competitive selection, competitive negotiation and electronic auction.The ISO 10845 series covers operational process, whereas this standard dealswith policy in establishing a procurement strategy
28、 and setting up a system.1 ScopeThis British Standard gives recommendations and guidance on the developmentwithin a public or private sector organization of policies, strategies andprocedures for the procurement of construction in the built environment usingthe structure shown in Figure 1.It does no
29、t cover the procurement of associated engineering services andoffshore construction works or the procurement of facilities management as astand alone service.BRITISH STANDARD BS 8534:2011 BSI 2011 12 Normative referencesThe following referenced documents are indispensable for the application ofthis
