SUE Studies

University of Toronto SUE Study
The Ontario Sewer and Watermain Contractors Association commissioned the University of Toronto to investigate the practice of using SUE on large infrastructure projects in Ontario. The study chose nine case studies and determined that the average rate of return for each dollar spent on SUE services on these projects was $3.41. The study also made a number of qualitative recommendations regarding the use of SUE.

Purdue University SUE Study
The Federal Highway Administration (FHWA) commissioned Purdue University to determine how effective SUE is at reducing costs on highway projects. The study selected 74 highway projects from across the USA and determined that on average every dollar spent on a SUE investigation resulted in $4.62 of project savings. Out of all the projects only three had a negative return on investment.

Stevens Paper
An investigation by R.E. Stevens, presented at the International Conference of the Society of American Value Engineers, showed that the use of SUE services resulted in overall project savings of 10-15%.
