This is the first demonstration project regarding a new form of contract - "Design, Construct and Maintain (DCM)" contract. The report describes the project. A 6200m section of the gravel road was reconstructed at a cost of about SEK 1.7m. 4 years of the 7-year maintenance period have expired. A DCM contract necessitates a new interface between client and contractor. Keeping a gravel road in good repair requires close interplay between service and maintenance measures. The client specifies the road standard; the contractor aims to minimise the life cycle cost for the first 5-10 years. The client's costs in drawing up tender documents were reduced. Contract supervision costs were practically nil since the contractor is responsible for maintenance over 7 years. Final cost was SEK 270/m of road. During the 4 years the contractor has reinforced some slopes and relocated some culverts to improve drainage. Contractor's maintenance costs so far have been ca SEK 10,000. The client (road authority) considers that the specified road standard has been delivered. As far as contractor is concerned, he could by realigning the road save money on excavation, blasting, etc. One of the advantages is that changes can be made as the contract proceeds without the client having to be consulted. The work was carried out with strict compliance to specifications since maintenance responsibility would last for 7 years. (TRRL)
