Mechanical Capabilities

BIM Expertise

We utilize Building Information Modeling (BIM) to create 3D mechanical models (using Revit and other similar tools) for seamless integration of our design with the architecture.

Collaboration & Communication

Our engineers work closely with architects, owners, and designers from the creation of individualized design criteria to the project's customized engineering approach to ensure a practical design inline with our clients vision.

Innovative Approach

We have experience utilizing various heating and cooling systems to ensure the architectural intent and interior design parameters are maintained throughout the design.

Green Engineering - Building Efficiency Experts

DAE uses the latest analysis methodologies and materials to evaluate and implement the latest green energy technologies.

What Our Clients Say

We work with a range of clients including architects, builders, owners, and consultants.

“Dilandro Andrews Engineering is a full service firm who just introduced solar and energy storage design to their qualifications. Great service.”

Michael Passantino

Southampton, New York

“My interaction with the team at DiLandro Andrews thus far has been very positive. They have diligently listened to all my issues and worked to address them in a timely fashion. They were asked to reinvestigate the work of another firm and this they did very professionally. I would have no reservations in working with them in the future or recommending them to other colleagues.”
