I am looking to evaluate contract type as a factor that influences project success contrary to established factors like project manager/engineers experience and performance among others. I currently have results using AHP only.
I would say that it depends on how you classify contracts (your 'contract type').
Have a look at:
Chen, L., Manley, K., and Lewis, J. (2012). Exploring governance issues on collaborative contracts in the construction industry. In G. Shen, Q. Ma, J.K.H. Chung, A.T.W. Yu (Eds.), Proceedings of the International
Conference on Value Engineering and Management, December 6-7. Hong Kong: Hong Kong Polytechnic University.
There is plenty of literature on construction procurement.
Thierry Fausten thank you. I’m considering the most common types of contract; fixed/lump sum contracts, time&material, unit pricing and cost plus contracts.
Are you thinking of U.S. domestic contracts, or international contracts such as the various FIDIC contract variations? With or without Dispute Board, Dispute Adjudication or other ADR provisions? Those can make a huge difference in whether projects are on, ahead or behind schedule. They also significantly impact whether projects are on, under or exceed the budget. I have been an arbitrator mediator and Construction Dispute Board Chairman and will be happy to assist you any way I can.
