What We Do

Whatever issue you face, we have your solution. We get to the heart of every problem—digging deep to understand its intricacies and nuances, so we can help you achieve your goals, together.

Laboratory & Research

With extensive experience in design for everything from life sciences research to materials engineering and astrophysics, our multidisciplinary teams design research facilities that perform.

Construction Engineering

Our integrated team approach brings together developers, contractors, designers, fabricators and erectors early on to manage risk, improve schedule and control costs.

Envelope Renewal

From hands-on investigation and analysis to repair or restoration for any material or building type, we can help you meet all your building enclosure renewal needs.

Project Certification

We are experts in the integrative design process, and we use this skill to help your project achieve the highest green building certification possible given the project budget and goals. 

Transportation & Infrastructure

In designing the transportation infrastructure for today’s cities, we consider the larger contexts of security, maintenance, and traveler convenience.

Our Projects

We are conquering complex problems - on six continents - and finding better ways to tackle even the most straightforward undertakings.
