Accordingly, the possibility of using identical
28、 machines from one site to another is usually remote because of many variations in basic design and operating conditions. For this reason, it is not feasible in a single publication of this type to develop standard documents which cover a wide range of site specific applications or to specify in det
29、ail the various machine types. However, the technical report will assist in preparation of Tendering Documents (TD) through the use of a common layout which takes advantage of uniformity and the time-saving features of word processing software. A uniform approach of the type proposed will make it ea
30、sier for the Employer to prepare the Tendering Documents and for the Tenderer to prepare its proposal. The report outlines the various chapters needed for a complete set of Tendering Documents, together with comments on the purpose of each and discussions as necessary. The guide is intended to assis
31、t in making certain that information is placed in the appropriate section; thereby avoiding possible conflict or duplication. This results in a greater degree of completeness in the documents and adds to their adaptability and ease of updating while minimizing misinterpretations. The main objective
32、for inviting competitive tenders for hydraulic machines is to purchase the most economical equipment which will meet the performance requirements of the specific site. The capital investment in machinery is a significant one; it can range from20% to50% of project costs. The value of machine performa
33、nce becomes an important item of concern in the purchasing process. This guide contains some information on methods of evaluation and means of establishing performance criteria to assist in achieving optimum equipment selection. In preparing Tendering Documents, cognisance should be taken of problem
34、s which may be encountered by unnecessarily restrictive specifications, particularly when applied to machines of small to moderate sizes within the range covered by the guide. Restrictive requirements may add significantly to the cost of the equipment without a proportional gain in its reliability o
35、r performance. It is important therefore that Tendering Documents properly define and describe, in an effective manner, the specific conditions of operation, size, number of units to be installed, and special features required, if any. Tendering Documents which require an inordinate amount of inform
36、ation from Tenderers can also unnecessarily increase the costs for preparing and evaluating tenders. This may also unnecessarily restrict the successful Contractors freedom to apply an optimal design and may deter the Tenderer from tendering at all. Information requested in the technical data sheets
37、, therefore, should be limited to that which is really essential for evaluation and comparison of tenders by the Employer and engineer. In conclusion, this guide should not be used to replace the engineering effort needed in the selection, design, manufacturing, installation, and testing of the mach
38、ines and associated systems; nor does it contain complete detailed specifications and descriptions of conditions or components. It is assumed that qualified engineering personnel will be engaged on the project to undertake the necessary evaluation of site conditions and selection of equipment which
39、will meet the performance, operation, reliability, and maintainability criteria established for the project. 1 Scope and object This technical report, referred to herein as the “Guide”, is intended to assist in the preparation of Tendering Documents and tendering proposals and in the evaluation of t
40、enders for hydraulic machines. The object of this technical report is to provide a general guide for preparation of Tendering Documents (TD) for the supply, installation and testing of hydraulic turbines, storage pumps, and pump-turbines herein referred to as hydraulic machines as defined in2.2 of t
41、his publication. This technical report considers the case where both equipment supply and site installation are carried out by the same Contractor. In those cases where site installation is not included in the scope of work, the Tendering Documents should include supplementary provisions for site su
42、pervisory services to be provided by the equipment supply Contractor and for day-to-day interface with the site installation Contractor. Hydraulic machines for small units with power less than5MW and with runner/impeller diameters less than3m are covered in IEC61116. These limitations are not intend
43、ed to be absolute and will depend on the type of machine and on other project characteristics.BSIEC61366-1:1998 2 BSI 06-1999 2 Reference documents and definitions 2.1 Reference documents 2.1.1 Application of reference documents The adoption of reference documents can greatly assist users of this gu
44、ide by avoiding unnecessary duplication of standards and codes which have gained industry acceptance. There are a number of sources for reference documents such as IEC, ISO, regional or national standards, and other recognized standards. It is strongly recommended that users take advantage of such s
45、tandard documents in preference to developing new versions for similar requirements. The Employer should be prepared to provide copies of non-international standards to the Tenderers and/or the Contractors upon request. 2.1.2 IEC publications IEC publications (in their latest revision), as they appl
46、y, should be used and referenced in the preparation of Tendering Documents and the related technical specifications. The list of IEC publications relating to hydraulic machinery is as follows: IEC60027, (all parts), Letter symbols to be used in electrical technology. IEC60041:1992, Field acceptance
47、tests to determine the hydraulic performance of hydraulic turbines, storage pumps and pump-turbines. IEC60617, (all parts), Graphical symbols for diagrams.
