Do You Have An Engineering Project We Can Help With?

Market Overview

Servicing Multiple Industries

Since our founding in 1991, this approach has delivered results for our firm and our clients. Over the years, some of the world’s largest organizations—Delta Airlines, Forbes, Honeywell, Pfizer, and others—have asked us to partner with them. We are experts in such uncompromising categories as airports and laboratories. In all, we have completed more than 2,000 successful projects, thanks to a team of professionals (many with 35-40 years’ experience) who look forward to coming to work every day to serve our clients.


Servicing the Friendly Skies

Since 1991, Guth DeConzo has completed over 500 projects at PANYNJ facilities (JFK International Airport, Newark International Airport & LaGuardia Airport). Projects include concession spaces, 1st Class Lounge projects, food courts, GSE facilities, hold rooms, ticket counters, baggage handling facilities, jet bridges, security checkpoints, cargo facilities and Ops level renovations. Our clients include Delta Air Lines, American, United, Southwest, US Airways, Continental, SAS, Jetblue, Emirates, Air India, and British Airways.

We have on-going work at over 20 airports across the country including Logan, Philadelphia, Dulles, Reagan National, Bradley, Orlando, Miami, O’Hare, Las Vegas, San Francisco, Nashville, Memphis, DFW, Raleigh Durham and Seattle. In addition, we have completed car rental facilities at airports for Avis, Enterprise, Budget, Dollar and Hertz.


Lowering Business Bottom Lines

Business systems must juggle a raft of complex demands: cost savings, energy efficiency, worker safety, reliability and tenant satisfaction. Guth DeConzo solutions have met these demands for some of the world’s best-known companies, delivering complex solutions at the lowest attainable cost.  

Guth DeConzo has extensive experience in both new commercial construction and renovations of commercial tenant spaces. Projects have included new high rise construction and conversions of industrial and factory buildings to commercial spaces. Tenant renovations have ranged from 5000 square feet to several hundred thousand sf.

Higher Education

Dorms & More

Guth DeConzo has leveraged its strengths in project management and client collaboration across a range of complex projects—like replacing 30,000 light fixtures in 56 dorm buildings, mostly during the few weeks when students were away. 


Streamlining Health Care Environments

Due to the critical nature of the health care environment, attention to detail is critical. Through our experience in design, commissioning and construction management, we can bring years of experience to ensure that projects are designed and constructed to ensure systems operate efficiently and resiliently. 


Saving Schools Money

With tight budgets and significant maintenance issues, K-12 systems demand the kind of expertise and hands-on involvement that Guth DeConzo brings to every project. One of our recent energy conservation projects generated $250,000 in annual savings for the school district. 


Keeping Labs Operational

Few environments are more sensitive than laboratories, where even a brief power loss or HVAC incident can ruin critical experiments. As a result, projects require extraordinary levels of e collaboration, planning, and attention to detail—all of which we have brought to lab buildings of all types.

Street Lighting

Saving Energy, Improving Light Quality

Guth DeConzo has replaced approximately 20,000 street lights across New York State with 50,000 more in the design phase. That includes such high-profile projects as street lighting for MTA bus terminals, the City of White Plains, and the New York State Thruway. We understand the ins and outs of local codes, technology capabilities, photometrics and aesthetics, which are critical to implementing a project which will save energy and improve light quality. 


More Comfortable Living Spaces

Guth DeConzo has extensive experience for both new construction and renovations of existing residential buildings in NYC. Projects have included new high-rise construction, conversions of industrial building, complete renovations of highrise pre-war buildings on the upper east and upper west sides, and renovations of individual high end apartments, penthouses and lofts.
