Our Services

Design & Development

Excellent design is our top priority, and it could not be possible without technical understanding. We work as engineers with designer sympathies, ensuring a perfect unison between the design and its technical performance. Our experience and expertise is vast and diverse. We’ve worked on projects as large as towers and small as toilet rooms.

  • Schematic design
  • Design development
  • Contract documents
  • Bidding phase support
  • Construction administration

Structural Engineering

Structures have the potential to answer even the most improbable questions with sensitivity.  A great structure remains elegant and efficient when faced with balancing the requirements of the ground condition, the installation constraints, cost, and design intent. We have experience working on a diverse portfolio of projects: minute and massive.

  • New construction
  • Detail engineering for contractors
  • Design Development
  • Renovation & adaptive reuse
  • Structural investigation & Failure Evaluation
  • Peer Review & Value Engineering
  • Support of Excavation (SoE)

Facade Engineering

The building envelope is an art and a science. Skins have the potential for elegance, livelihood, and to become icons for their inhabitants and neighborhoods. But they shouldn’t leak. We take pride in a technical but design-oriented approach; to achieve both is our top priority. We produce advanced structural analysis and shop drawings together to seamlessly fuse design and performance.
