Duffy’s innovative approach to “Sustainability”, “Green Building” and “Lean” Construction practices

Our continuing efforts to bring our clients the latest and the best in construction technologies leads us to the issues of Sustainability, Green Building, and Lean Construction as they pertain to YOUR PROJECT.

Like all good construction projects, sustainable/green projects begin with an integrated design process. Combining the integrated design process, with our innovative, time tested, and proven budgeting, cost/benefit analysis, constructability, planning and scheduling methods result in realistic budgets for your sustainable/green building.

When the Sustainable and Green Building initiatives became common place nearly 10 years ago, Duffy began integrating these initiatives into our projects. Our indoctrination began as clients started incorporating the Illinois Department of Commerce and Economic Opportunity's (DCEO) energy grants into their financing program. Shortly thereafter the City of Chicago's and the Illinois Housing Development Authority's tax credit programs incorporated green check lists as part of their scoring systems. As these programs grew we expanded our coverage and obtained memberships in Green Building and Sustainable Construction Organizations such as the US Green Building Council (USGBC). Our specialization enables us to provide cost benefit analysis, product recommendations, and data regarding sustainable/green products and systems which result in obtaining LEED Certification levels and savings on future operating expenses. With a number of LEED AP BD+C certified staff in the Duffy organization we are able to manage LEED projects from conception thru construction completion and commissioning.

Duffy has been incorporating Lean Construction principles and practices into all of our projects for decades. The large number of satisfied repeat clients is testament to our time tested proven approach to the whole project. Our innovation and commitment to success continues to make the Joseph J Duffy Company a leading General Contractor since 1923.
