The five groups prequalified in March to bid for the Disi water conveyance project have received a letter of invitation to comment on the technical and financial aspects of the construction tender, according to deputy secretary-general of the Water & Irrigation Ministry Fayez Batayneh. 'Draft documents have been distributed to the companies and we have invited any comments to be made by 12 May,' he said in early April in an interview with MEED. 'It is moving ahead steadily and in a relaxed manner. We will distribute final tender documents afterwards and hope to make a decision on the contractor by the end of the year.'
