GCC is currently contracted to conduct formal Partnering on behalf of the Department of State, Overseas Buildings Operations (OBO) as a pilot project to determine if Partnering would be a viable addition to nurture the spirit of collaboration on current and future OBO construction projects worldwide.

Gregory Grabowski is currently conducting Partnering facilitation services on behalf of this team both domestically and on-site in Kampala, Uganda.

GCC Services: Partnering

“Gregory and the GCC involvement in our project have been pivotal to our recent successes and have created a monumental change in our effectiveness and trajectory towards success. They have been the stewards of the Partnering process and we have realized more effective communication, better operational relationships, and the ability to quickly and fairly resolve disagreements and disputes, without any negative fallout. This has been a fantastic investment and has already paid out very well.”
