Cost overruns in construction contracts tendered by the Swedish Transport Administration (English)
Abstract [sv]

Trafikverket har regeringens uppdrag att verka för en ökad produktivitet i anläggningsbranschen. VTI bistår Trafikverket i detta arbete. I denna rapport redovisas de skillnader som finns mellan det pris som fastställs i ett entreprenadkontrakt mellan Trafikverket och det företag som fått i uppdrag att genomföra en verksamhet och slutkostnaden för uppdraget. 776 kontrakt som avser entreprenader inom både väg- och järnvägssektorn och såväl investeringar som underhållsåtgärder och som kostar mer än 10 miljoner kronor, ingår i materialet.

Statistiska tester visar bland annat att risken för kostnadsöverskridanden är mycket stor och något högre för järnvägskontrakt (94 procents sannolikhet) än för vägkontrakt (86 procent). Slutkostnaden för vägkontrakt överskrider kontraktssumman med 20 procent vilket är signifikant lägre än för järnvägskontrakt där slutkostnaden i genomsnitt är 32 procent högre.

Abstract [en]

The Government has instructed the Swedish Transport Administration (Trafikverket) to promote productivity in the construction industry. VTI assists Trafikverket in this work. In this report, the differences that exist between the price set in the contract between Trafikverket and the construction company that has been commissioned to implement an activity and the final cost of the assignment are reported. 776 contracts relating to contracts in both the road and rail sectors and that comprises both investments and maintenance measures and which cost more than SEK 10 million are included in the material.

Statistical tests show, among other things, that the risk of cost overruns is very large, and slightly higher for railway contract (94 per cent probability) than for road contracts (86 per cent). The cost overrun for road contracts (1,20) is significantly lower than for rail contracts (1,32).
