WHEREAS THE SIMULTANEOUS ATTAINMENT OF FREEDOM OF ESTABLISHMENT AND FREEDOM TO PROVIDE SERVICES IN RESPECT OF PUBLIC WORKS CONTRACTS AWARDED IN MEMBER STATES ON BEHALF OF THE STATE , OR REGIONAL OR LOCAL AUTHORITIES OR OTHER LEGAL PERSONS GOVERNED BY PUBLIC LAW ENTAILS NOT ONLY THE ABOLITION OF RESTRICTIONS BUT ALSO THE CO-ORDINATION OF NATIONAL PROCEDURES FOR THE AWARD OF PUBLIC WORKS CONTRACTS ;

WHEREAS SUCH CO-ORDINATION SHOULD TAKE INTO ACCOUNT AS FAR AS POSSIBLE THE PROCEDURES AND ADMINISTRATIVE PRACTICES IN FORCE IN EACH MEMBER STATE ;

WHEREAS THE COUNCIL , IN A STATEMENT CONCERNING THE AFOREMENTIONED GENERAL PROGRAMMES , HAS STRESSED THAT CO-ORDINATION SHOULD BE BASED ON THE FOLLOWING PRINCIPLES : PROHIBITION OF TECHNICAL SPECIFICATIONS THAT HAVE A DISCRIMINATORY EFFECT , ADEQUATE ADVERTISING OF CONTRACTS , THE FIXING OF OBJECTIVE CRITERIA FOR PARTICIPATION AND THE INTRODUCTION OF A PROCEDURE OF JOINT SUPERVISION TO ENSURE THE OBSERVATION OF THESE PRINCIPLES ;

WHEREAS SOME OF THE BODIES WHICH CURRENTLY ADMINISTER TRANSPORT SERVICES IN THE MEMBER STATES ARE GOVERNED BY PUBLIC LAW AND SOME BY PRIVATE LAW ; WHEREAS , IN ACCORDANCE WITH THE OBJECTIVES OF THE COMMON TRANSPORT POLICY , EQUALITY OF TREATMENT SHOULD BE ENSURED NOT ONLY BETWEEN SEPARATE UNDERTAKINGS CONCERNED WITH A SINGLE MODE OF TRANSPORT BUT ALSO BETWEEN SUCH UNDERTAKINGS AND UNDERTAKINGS CONCERNED WITH OTHER MODES OF TRANSPORT ;

WHEREAS , THEREFORE , PENDING THE ADOPTION OF PROVISIONS CONCERNING THE CO-ORDINATION OF PROCEDURES WHICH TAKE INTO ACCOUNT THE SPECIAL CIRCUMSTANCES DESCRIBED ABOVE , IT IS NECESSARY TO EXCLUDE FROM THE SCOPE OF THIS DIRECTIVE AUTHORITIES REFERRED TO ABOVE WHICH , BY REASON OF THEIR LEGAL STATUS , WOULD FALL WITHIN ITS SCOPE ;

WHEREAS IT IS NECESSARY TO AVOID THE SUBJECTION OF THE PRODUCTION , DISTRIBUTION AND TRANSMISSION OR TRANSPORTATION SERVICES FOR WATER AND ENERGY TO DIFFERENT SYSTEMS FOR THEIR WORKS CONTRACTS , DEPENDING ON WHETHER THEY COME UNDER THE STATE , REGIONAL OR LOCAL AUTHORITIES OR OTHER LEGAL PERSONS GOVERNED BY PUBLIC LAW OR WHETHER THEY HAVE SEPARATE LEGAL PERSONALITY ; WHEREAS IT IS THEREFORE NECESSARY TO EXCLUDE FROM THE SCOPE OF THIS DIRECTIVE THOSE SERVICES REFERRED TO ABOVE WHICH BY REASON OF THEIR LEGAL STATUS , WOULD FALL WITHIN ITS SCOPE UNTIL SUCH TIME AS A DEFINITIVE SOLUTION CAN BE ADOPTED IN THE LIGHT OF EXPERIENCE ;

WHEREAS WORKS CONTRACTS OF LESS THAN 1 000 000 UNITS OF ACCOUNT CAN , FOR THE MOMENT , BE EXEMPTED FROM COMPETITION AS PROVIDED FOR UNDER THIS DIRECTIVE , AND IT IS APPROPRIATE TO PROVIDE FOR THEIR EXEMPTION FROM CO-ORDINATION MEASURES ; WHEREAS , IN THE LIGHT OF EXPERIENCE , THE COMMISSION WILL AT A LATER DATE SUBMIT TO THE COUNCIL A NEW PROPOSAL FOR A DIRECTIVE WHOSE AIM IS TO LOWER THE THRESHOLD FOR THE APPLICATION OF CO-ORDINATION MEASURES TO PUBLIC WORKS CONTRACTS ;

WHEREAS TO ENSURE DEVELOPMENT OF EFFECTIVE COMPETITION IN THE FIELD OF PUBLIC CONTRACTS IT IS NECESSARY THAT CONTRACT NOTICES DRAWN UP BY THE AUTHORITIES OF MEMBER STATES AWARDING CONTRACTS BE ADVERTISED THROUGHOUT THE COMMUNITY ; WHEREAS THE INFORMATION CONTAINED IN THESE NOTICES MUST ENABLE CONTRACTORS ESTABLISHED IN THE COMMUNITY TO DETERMINE WHETHER THE PROPOSED CONTRACTS ARE OF INTEREST TO THEM ; WHEREAS , FOR THIS PURPOSE , IT IS APPROPRIATE TO GIVE THEM ADEQUATE INFORMATION ABOUT THE SERVICES TO BE PROVIDED AND THE CONDITIONS ATTACHED THERETO ; WHEREAS , MORE PARTICULARLY , IN RESTRICTED PROCEDURES ADVERTISEMENT IS INTENDED TO ENABLE CONTRACTORS OF MEMBER STATES TO EXPRESS THEIR INTEREST IN CONTRACTS BY SEEKING FROM THE AUTHORITIES AWARDING CONTRACTS INVITATIONS TO TENDER UNDER THE REQUIRED CONDITIONS ;
