Projekteringsupphandling i nya former: förstudie

This paper describes current practices to tender the projection of infrastructure construction projects and the problems which emanate from these routines. Three approaches to handle these problems are suggested. One method is to increase the use of fixed price, rather than the present use of unit price contracts. A second means would be to further develop the techniques for remunerating bidder competence when submissions are evaluated, in the first place by establishing efficient means for combining price and quality in the assessment. A third approach is to select the winning bid for projection base not only on the price quoted for the projection assignment per se, but also to account for the bidders' ex ante estimate of the subsequent construction cost. The winning bidder would then be remunerated with a share of further cost savings but also pay for part of the costs which exceed the ex ante expectation. This provides incentives to develop implementation methods that would save on construction costs at large.

The principal would therefore switch from buying the consultants time over to tendering the final outcome of a construction project where the consultancy is instrumental in finding innovative implementation techniques. The report is a pre-study and should be seen to suggest approaches which must be further developed and tested before full-scale implementation. The work is undertaken against a background of Sweden's construction industry lagging behind other parts of the economy in terms of productivity and costs.
