Doug was the claims and estimating manager for Harris & Associates on Construction Package 1 from November 2018 through May 2019. During that period Doug made a significant impact to the program. He was able to get up to speed very quickly on this complex $1.6b design-build package. His understanding of the contract and scope of work was exceptional. During meetings with the contractor and Authority Doug demonstrated acute competency and professionalism. I'm not surprised that Doug is thriving in his consultancy business and would highly recommend him as an industry expert.

Doug was an integral part of our team's success in defending a client against a major construction claim. Doug's ability to decipher the construction record using his experience and technical background gave us a litigation advantage.

Very Happy with the lines of communication for the OMC building…The volume of changes on the OMC building were addressed timely. D. Oppman and B. Smith’s effort to keep PMI on-time with RFI and change documentation has been very good. Good effort in keeping on top of the OMC subcontractor.

Doug has been CorVasc’s “Owners Agent” on our new medical office building. He has identified numerous opportunities for improvement in safety and scheduling where better co-ordination of the trades was required. He also recommended several value-engineering initiatives and pressed contractual commitments that have resulted in material cost savings for Corvasc.

Doug Oppman has worked for me as an employee of Bovis Lend Lease as Senior Project Manager . Doug has been a strong project leader in a variety of roles in support of the $1.0 billion, multi -year, Indianapolis Maintenance Center Project and for a number of other multi-million dollar projects managed through United’s East Region Corporate Real Estate office… He is a thoughtful, dedicated, hardworking professional who tenaciously works with colleagues, contractors and owner’s representatives to find and implement effective solutions to the owner’s needs. I consider myself fortunate to have had Doug as my colleague…

Based on my twenty-two years of experience in working with contractors on school building projects, I have found Mr. Oppman’s work to exceed the norm and go beyond the call of duty. Over the course of the last two years he has worked with our $25M project on two sites… He has revised and accelerated architect phasing in order to accommodate student needs, and worked hard to overcome design deficiencies in an economical manner. I recommend him without hesitation.
