Abstract : This work compares the performance of traditional construction projects with alternative approaches. It verifies significant advantages for partnered, design-build, and combination projects. Next, a method is developed for measuring 'degree of interaction' (DOI) to approximate project integration. DOI is shown to directly impact project performance, and can be used to predict future project performance. Of 209 completed military construction projects, partnered projects averaged the least schedule growth, design-build projects the lowest cost growth and design deficiencies, and combination projects the fewest modifications. Traditional projects had the worst average schedule growth, modifications, and design deficiencies. DOI scores were calculated for 38 of the 209 projects. The alternative projects have significantly higher average DOI scores than traditional projects. Scatter plots comparing DOI and project performance show a clear relationship between the two. As DOI scores rise, project performance quickly improves and becomes more consistent. Beyond a certain DOI score (approximately 0.4), performance levels off. Achieving this score takes only a modest increase in interaction. Performance is significantly better for projects with DOI scores above 0.4. Interaction occurring early in the project also has a positive impact on performance. Finally, future project performance can be predicted based on DOI scores. The probability of improved average performance for projects with DOI>0.4 is very high. Future projects with a DOI score over 0.4, should average significantly less cost growth, schedule growth, fewer modifications, and design deficiencies, over comparable projects with DOI<0.4.
