M/E/P Engineering

Our engineers take an exceedingly thorough approach to evaluating the unique MEP requirements associated with each project. From ensuring the correct level of heating and cooling throughout a building, to providing electrical service supporting current and future operations, and ensuring the appropriate level of fire protection we design systems that are engineered within the context of the project. Our LEED® certified professionals evaluate the life cycle cost analysis in order to minimize operating expenses and energy needs, increase efficiency, and consider the long-term value for each project. We understand that each client has unique system guidelines and preferences and LDG knows how to accommodate those differences.
