For and on Behalf Management This is a typical supplier/customer partnership situation whereby De Smet Engineers & Contractors (DSEC) executes part or all equipment and services implementation activities for and on behalf of the customer. Based on DSEC’s management, engineering and purchasing procedures, the customer participates actively in all purchase decision in full collaboration with DSEC. Orders are then directly placed by the Customer through DSEC’s administration. As project overall budget and time frame can nevertheless be guaranteed by DSEC, this set-up provides generally the best compromise between efficiency and cost savings without hampering the overall project management reliability.
