5、ment The SABS Standards Division wishes to acknowledge the valuable assistance derived from the publication of EN 13269. Foreword This recommended practice is a technical agreement developed in accordance with SANS 1-1, and approved by SABS TC 50, Maintenance contracts. This document was published i

6、n March 2009. This document was based on EN 13269:2006. Introduction The value of maintenance to the owners of items (as defined in SANS 53306) cannot be overemphasized. Proper maintenance protects the value of the capital invested and ensures that the required availability is attained. In addition,

7、 as technical and economic developments increase, the demand for contracted maintenance services also increases. Maintenance contracts should be approached in a structured and careful manner. This document is simply a working tool intended for parties who wish to draw up a maintenance contract. It o

8、ffers headings which are not exhaustive and which parties could or could not include, exclude, modify and adapt to their own contractual relationship. Not all the clauses discussed in the Guidelines for the preparation for maintenance contracts will be applicable to every contract. Each individual c

9、ontract should be drafted, and negotiated where appropriate, to take into account the requirements arising from the work required on the items to be maintained, the parties involved and any applicable laws and regulations. This recommended practice contains the following clauses to assist the user:

10、Clause 4 gives a structured overview of possible maintenance services offered or required. Its purpose is to give advice on activities which may be required in preparing a contract and prior to signing of agreements and also those activities which may be required during the period of any contract; a

11、nd Clause 5 provides a standard checklist for use when drafting maintenance contracts together with important elements for content.

14、w attention to the scope of maintenance services and to identify options for their provision, d) give assistance in, and advice on, the drafting and negotiation of maintenance contracts and in specifying arrangements in the case of dispute, e) identify types of maintenance contracts and to make reco

15、mmendations for the attribution of rights and obligations between the parties of the contract including risks, and f) simplify comparison between maintenance contracts. 1.2 This recommended practice provides guidance on the preparation of contracts for maintenance work. It can be applied to a) emplo

29、owed: Step 1: The employer should decide which maintenance services will be provided in-house and which services will be contracted out; i.e., which maintenance services should be bought from a maintenance service provider and therefore be subject to a maintenance contract; Step 2: An expression of

30、interest stage follows any decision to contract out part or all of any maintenance and it is during this period that the employer will identify any service provider or service providers with the capability of performing the required maintenance tasks; Step 3: The contract may be prepared using the g

31、uidelines in this recommended practice and the maintenance service provider selected either by price negotiation or by competitive tender. 4.1.2 Activities can be broadly divided into those required prior to the signing of the contract and those required after it has been signed. 4.2 Pre-contract ac

32、tivities These consist of actions, which are required prior to preparing, and in order to prepare, a contract. Such actions may comprise the following: ARP 078:2009 Edition 1 6 a) identifying the maintenance service required; b) preparing a maintenance policy and a strategy for its implementation; c

33、) making a decision on whether to provide the maintenance service in-house or to contract it out; d) deciding the type of maintenance contract which may be appropriate and preparing the required specification; e) identifying maintenance service providers who are capable of carrying out the tasks req

34、uired; and f) preparing the contract. 4.3 Procurement This consists of the following actions: a) preparing expression of interest and procurement documents; b) calling for tender or negotiating a price (or both); c) evaluating the returned tenders received and selecting the successful maintenance se

35、rvice provider; and e) awarding the contract. 4.4 Contract activities 4.4.1 These activities consist of those actions to be carried out by the maintenance service provider and those which will be carried out by the employer after the contract has been signed. 4.4.2 There should be adequate liaison b

36、etween each party to ensure the smooth running of the contract. NOTE In case of contracts of several years duration, the parties should agree on a periodic verification and validation in order to adjust the contracts. 4.4.3 The maintenance service providers actions may cover a) supplying labour, mat

37、erial and equipment to complete the work required by the contract, this may include dividing the work down into discrete tasks, b) preparing a work programme and carrying out the work in accordance with that programme and the requirements of the contract, c) providing the management required to cont

38、rol the programme of work at every stage, d) submitting claims for payment in the format as required by the employer, e) management of possible contract changes, and f) management of all safety and environmental issues.
