This is an arrangement more commonly adopted for complex building construc- tions rather than for civil engineering works. Under it the promoter appoints one contractor to manage all the construction inputs by letting contracts him- self. These ‘works contracts’ are effectively sub-contracts to the management contractor. Many may be labour-only contracts, while others are for ‘supply and erect’. The promoter may retain rights to approve or disapprove appointment of a works contractor. The promoter may also let a separate design contract, which is placed under the administrative charge of the management contractor. Advantages are that the promoter is relieved of the responsibility for the letting of the many.
