Construction Statistics

[Jared Tillery]

I am a project engineer working for a national developer.  We are doing some research on finding the average on time completion percentage for multifamily projects over $20 million dollars.  For example, 92% of multifamily projects finished on time for a firm or in the industry, 4% are completed 10% over schedule and 4% completed 20% over schedule.

Does anyone know of some reliable resources that may be able to provide some information?  I have already checked with the Census and BLS.

Anything might help.  Thank you.
