THE REFERENCES MENTIONED THEREIN . UNDER THE SECOND PARAGRAPH, THE AUTHORITIES AWARDING CONTRACTS ARE REQUIRED TO SPECIFY IN THE NOTICE OR IN THE INVITATION TO TENDER WHICH REFERENCES THEY HAVE CHOSEN FROM AMONG THOSE MENTIONED IN THE PREVIOUS PARAGRAPH "AND WHAT REFERENCES OTHER THAN THOSE MENTIONED UNDER ( A ), ( B ) OR ( C ) ARE TO BE PRODUCED ".
9 IT CAN BE SEEN FROM THE VERY WORDING OF THAT ARTICLE AND, IN PARTICULAR, THE SECOND PARAGRAPH THEREOF, THAT THE LIST OF REFERENCES MENTIONED THEREIN IS NOT EXHAUSTIVE .
10 THE REPLY TO THE NATIONAL COURT MUST THEREFORE BE THAT THE REFERENCES ENABLING A CONTRACTOR' S FINANCIAL AND ECONOMIC STANDING TO BE DETERMINED ARE NOT EXHAUSTIVELY ENUMERATED IN ARTICLE 25 OF DIRECTIVE 71/305/EEC .
THE QUESTION CONCERNING THE VALUE OF THE WORKS WHICH MAY BE CARRIED OUT AT ONE TIME
11 WITH REGARD TO THE NATIONAL COURT' S SECOND QUESTION IN CASE 27/86, IT SHOULD BE NOTED THAT THE TOTAL VALUE OF THE WORKS AWARDED TO A CONTRACTOR AT A PARTICULAR MOMENT MAY BE A USEFUL FACTOR IN DETERMINING, IN A SPECIFIC INSTANCE, THE FINANCIAL AND ECONOMIC STANDING OF A CONTRACTOR IN RELATION TO HIS OBLIGATIONS . SINCE THE REFERENCES ARE NOT EXHAUSTIVELY ENUMERATED IN ARTICLE 25 OF THE DIRECTIVE, THERE IS THEREFORE NO REASON WHY SUCH INFORMATION SHOULD NOT BE REQUIRED OF TENDERERS BY WAY OF A REFERENCE WITHIN THE MEANING OF THAT ARTICLE .
12 HOWEVER, IN THE LIGHT OF THE GROUNDS OF THE ORDER FOR REFERENCE, THE CONTENT OF THE BELGIAN LEGISLATION MENTIONED THEREIN AND THE ARGUMENTS BEFORE THIS COURT, THE NATIONAL COURT' S QUESTION MUST BE UNDERSTOOD AS ALSO SEEKING TO ASCERTAIN WHETHER A NATIONAL RULE FIXING THE MAXIMUM VALUE OF WORKS WHICH MAY BE CARRIED OUT AT ONE TIME IS COMPATIBLE WITH THE DIRECTIVE .
13 IN THAT REGARD, IT SHOULD BE NOTED THAT THE FIXING OF SUCH A LIMIT IS NEITHER AUTHORIZED NOR PROHIBITED BY ARTICLE 25 OF THE DIRECTIVE, BECAUSE THE PURPOSE OF THAT PROVISION IS NOT TO DELIMIT THE POWER OF THE MEMBER STATES TO FIX THE LEVEL OF FINANCIAL AND ECONOMIC STANDING REQUIRED IN ORDER TO TAKE PART IN PROCEDURES FOR THE AWARD OF PUBLIC WORKS CONTRACTS BUT TO DETERMINE THE REFERENCES OR EVIDENCE WHICH MAY BE FURNISHED IN ORDER TO ESTABLISH THE CONTRACTOR' S FINANCIAL AND ECONOMIC STANDING .
14 IN ORDER TO RULE ON THE COMPATIBILITY OF SUCH A LIMIT WITH THE DIRECTIVE AS A WHOLE, THE PURPOSE AND OBJECT OF THE DIRECTIVE MUST BE BORNE IN MIND . THE PURPOSE OF DIRECTIVE 71/305 IS TO ENSURE THAT THE REALIZATION WITHIN THE COMMUNITY OF FREEDOM OF ESTABLISHMENT AND FREEDOM TO PROVIDE SERVICES IN REGARD TO PUBLIC WORKS CONTRACTS INVOLVES, IN ADDITION TO THE ELIMINATION OF RESTRICTIONS, THE COORDINATION OF NATIONAL PROCEDURES FOR THE AWARD OF PUBLIC WORKS CONTRACTS . SUCH COORDINATION "SHOULD TAKE INTO ACCOUNT AS FAR AS POSSIBLE THE PROCEDURES AND ADMINISTRATIVE PRACTICES IN FORCE IN EACH MEMBER STATE" ( SECOND RECITAL IN THE PREAMBLE
