Pre Construction

The Foundation

Like any sound structure, ZDG believes that all successful projects are founded on early, sound decisions which begin during the pre-construction phase.

Our team of highly trained professionals build efficiencies from the start, creating a strict timeline of budgets, logistics, and scheduling, remaining completely focused on the ultimate goal of actualizing client visions. When unanticipated challenges arise, our experienced staff can problem-solve and address the challenges head-on to ensure the project stays on track.

The Structure

Like ZDG’s attention to clients’ needs throughout the project is not formulaic; with each project brings newly welcomed challenges, and our diverse staff remains fully focused on managing the project at every phase.

We provide technical support in all of the following stages of construction:

- Site Work
- Building Foundations and Structures
- MEPS
- Building Enclosures
- Interior Finishes

ZDG believes in taking a collaborative approach with all parties involved, and our project management team instills a rigorous checks and balances system to ensure safety. We use direct, collaborative communication with the clients, architects, engineers and design consultants, ensuring that we are unified in reaching the same goal. We understand that without a strong communication structure in place, the project cannot meet the high standards that ZDG expects to deliver with each new venture.
