Projects Well Managed

Vermeer North Atlantic


In 2013-2014 Alfredo Sire Development Corp. performed a ground-up project to construct a new branch location for our company on Fields Lane, Brewster. ASDC was contracted as the general contractor to perform all site work and building construction for the project.

Based on our experience, we can highly recommend the contracting services of ASDC. Their bid was concise, and pricing was fair. The construction schedule presented was realistic and was met on time with minimal issues. The quality of construction and products used was excellent. Most important has been the service received after the project was completed, During the 4 years after the project completion, ASDC has performed several warranty repairs in a timely manner, without issue.

Finally, the principal of ASDC Rob Alfredo along with his support staff was a pleasure to do business with. Not only were they honest and direct, but they were always available during and after the project for questions or concerns., I would highly recommend the services of ASDC.

JPI Architects

JPL Architects have worked with ASDC as a contractor on a car complex over the last few years.  The scope of the work included a building of 35,000 square feet and related site work such as drainage and extensive access drives.  ASDC provided us with quality workmanship and excellent time management.  I would highly recommend ASDC for any future projects.

Bibbo Associates, LLP

Our company has been working with ASDC for the past 20 years and Rob Alfredo and his group of professional site team and building constructors are second to none.  If there is ever a field change needed from our plans, ASDC is quick to point it out and resolve it immediately and as always they do a great job!

ASDC built a Mechanic Shop for us in Brewster, NY.  They did all of the planning and construction, in addition to staying within budget.  They were very efficient and easy to work with.
