Abstract: Engingeering cost management is discussed from thepoint d view d construction units and it is held thatengineering desigh is the key to engineering costmanagement. Construction units should actively perticipetein engineering design and keep technolgy in closecombination with economic benefits while enforcingcontract management and carrying out the project bid Astrict quality management system should be establishedbefore construction. During construction, the units shouldstrictly control attestations in-site, properly suplymaterials,and pay special attertion to extrabugetary fund.Finally keep the engineering cost in authorized limits anfinish the projects on schedule while guaranting quality.
