Established in 1997, Flintlock Construction Services is an open shop construction company erecting buildings exclusively in Manhattan. Founders Andrew and Stephen “Chip” Weiss Jr., fourth generation New York real estate development professionals, gained extensive open shop construction experience while building affordable housing in the Bronx and Brooklyn in the 1990s. That enabled the brothers to pioneer open shop construction, building with crews of non-union tradesmen in Manhattan. We’ve built more than 40 major projects in the heart of New York City over the past 15 years, including hotels and condominiums, municipal buildings, high rises and cultural institutions, delivering all construction projects 20 to 30 percent below the cost of similar closed shop construction projects. We’re reshaping the New York City skyline with our innovative practices and exacting standards of construction quality, safety, and value.

Our goal, as pioneers of open shop construction in Manhattan, is to help project developers achieve their visions as cost effectively as possible through our full range of services, while adding to our city’s vitality and quality of life. We are committed to maintaining leadership in the innovations we bring to the construction trade, and in our standards for workplace safety and ethical business practices. We are likewise dedicated to making sustainability a key feature of both the design and construction of the projects we work on, and to adapting technology for continuous improvements in the development and construction processes. If you have an interest in real estate development, a concern for quality, and care about New York City, we invite you to learn more about Flintlock Construction Services’ commitment to all three.
