I accepted an assignment of commissioning a 3,400 sq-ft project to apply for a LEED certification. I came in late in the game. It is a non-profit corporation and I´m doing the work as a volunteer service. The construction has been completed. The building is occupied. The owner is very happy with the project. But the documents for Owner Project Requirements and Basis of Design were never developed. What´s the best way to approach this situation?
