Research has shown a significant association of construction fatalities with design decisions, and Prevention through Design (PtD) has been hailed as an effective tool for the prevention of injuries on construction sites by addressing hazards during the design phase. The European Union (EU) identified this link and in 1989 enacted legislation requiring member countries to start practicing PtD.

Attempts to enact similar legislation in the United States have failed, and efforts to encourage designers to practice PtD in the general construction industry have not been very successful. Previous research has shown that in order to generate traction for PtD, it is essential to target owners, since they are seen as the group with the most influence for PtD. More importantly, the method with which that interest for PtD can be generated is by proving the business case. An evaluation and comparison of benefits and costs can be instrumental to encourage owners to demand PtD practice from their designers.

This paper describes the use of a multi-criteria analysis decision tool to evaluate between PtD solutions and traditional construction using two test cases. The line items used in the decision making tool were developed using the Delphi method, and the test cases were evaluated using input from industry professionals.
