Our
Difference

Team & Timing

Our experienced Property Needs Inspectors and Environmental Project Managers work closely to create a smooth client experience. A quick response to additional testing, such as NEPA, HAZMAT, PHASE II, and Radon and Asbestos services, is essential to satisfy deadlines that keep your deal moving forward.

Experience

Our subject matter experts (SMEs) comprise our environmental management team. The team often finds new opportunities to create efficiencies to coincide with HUD’s platforms and other environmental programs, such as HUD HEROS. With experience in all US regions, D3G is often selected to pilot new and challenging environmental platforms.

Data & Research

As environmental initiatives become more prevalent in multifamily and affordable housing, our team remains on the cutting edge of trends and upcoming regulatory changes. Paying attention to these developments allows us to better serve our clients with records, site reconnaissance, interviews, and written reports services. With access to data from over 20,000 site assessments, we can use technical blueprints to navigate any environmental concern.
