Discuss the most interesting or rewarding real estate project that you have worked on. A few years back I was the environmental project manager on a complex redevelopment project on a former landfill where hazardous contamination was identified right before construction was supposed to start.  The challenge was satisfying the federal and state agencies as quickly and cost efficiently as possible and get construction moving.  The project was completed on-time and on-budget and I won the American Civil Engineering Council Platinum Award for it. Besides the large challenges, it's the variety of projects that I find interesting, they're like snowflakes no two are ever exactly alike. At PW Grosser Consulting, Inc. our experiences range from Federal/State Superfund investigations through tank/spill closures.  However, environmental site assessments supporting due diligence for property transactions/refinancing deals is a fundamental component of PWGC's business. Our understanding of the nature of these projects and our rapport with the regulatory agencies remove environmental obstacles and allow projects to go forward efficiently.
