WAI staff is experienced in developing innovative and sustainable engineering solutions in concert with the development of the architectural design. Our design methodology allows engineering systems to blend with the building’s design themes thereby enhancing the architectural statement instead of overpowering or degrading it.
The principles of our methodology include: understanding the design intent, fulfilling the user’s needs, and harmonizing the engineering systems with the architectural design. The procedures of this methodology include: total quality management, and a comprehensive computer aided design and analysis approach. We implement the ideals of total quality management as an integral feature of this methodology; utilizing it throughout the development of the project. This entails: assuring our principles are embraced, maintaining communication between the design staff, utilizing check lists, and by review of the design by a second group of engineers not involved with the project that can provide a “fresh set of eyes.”
We offer the most technologically advanced mechanical, electrical, and plumbing design services in the metropolitan Washington-Baltimore area. WAI always invests in state-of-the-art technology. While technology gives us quality tools, our staff provides our clients quality service. Our employee professional development program and continuing education programs maintain our staff’s knowledge of the latest industry research. Together they provide knowledge, experience, understanding of issues, and technical capability on each project in a cost effective manner.
WAI’s engineers use the latest versions of AutoCAD and Revit for analysis, creating realistic 3D drawings, designing and drafting in a simultaneous integrated approach, and linking the most advanced analysis M/E software with the drawings. Our integrated technological approach produces clean, accurate, and coordinated construction documents in the most cost effective manner possible.
WAI staff is unique in that each individual has an intrinsic relationship with architecture and construction; most have either an Architectural Engineering degree or work experience in an Architectural Engineering firm. We blend architecture and engineering together recognizing the importance of aesthetics and constructability in each project. Our staff also brings extensive experience and a deep understanding of energy efficiency, innovative design, and sustainability. WAI’s design staff are comprised entirely of professional engineers; registered P.E.’s or E.I.T.’s.
Our staff is experienced in a broad range of project types including new design and retrofit projects. Many of these are of nationally recognized stature.
