facilities engineering

Our team uses contemporary design techniques to deliver efficient and effective security, communication, HVAC, audio/video, fire suppression, lighting, water, air, emergency power, fuel/energy distribution, process, and structural systems.

We utilize the latest technology including Building Information Modeling (BIM) to increase efficiencies in the design process and provide our clients with goal-oriented, quality design solutions that make sense to our clients and the environment.

By leveraging BIM, we optimize constructability and resolve building conflicts during design, not construction. Our structural engineers have served on the Pennsylvania Uniform Construction Code and Review Advisory Council while positioning LDG as industry leaders in pre-fab concrete and steel modular construction.

We team with architects and civil engineers to deliver innovative structural systems design to healthcare, industrial, commercial, civic/cultural, municipal, residential, higher-ed, and k-12 markets.
