It is Core Four Construction’s corporate philosophy that the client’s goals and business objectives are priority one.

Core Four construction was formed by Danny Sullivan. The company was created with the objective of providing quality real estate development services to the public and private sectors of the New York City metropolitan real estate and construction markets. Our company’s fundamental expertise is in the development and management of complex projects from concept through construction and beneficial occupancy.

As the company grew, our expertise within the construction industry expanded into new construction, interiors, additions and renovations. To meet the growing needs, our organization hand-selected an executive staff that has similarly performed in leadership roles for leading Construction Management and Architectural/Engineering firms throughout the industry. The executive team’s experience is extensive and involves several high profile clients.

Bearing this in mind, Core Four Construction was created to fill a void in this ever-changing marketplace. The company was founded on the principles of professionalism, cooperation, and efficiency.

Core Four Construction will customize a project management program tailored to fit the specific needs of each client and their project. It is essential for construction management firms to take steps to meet these challenges and focus on their clients’ objectives.

Having an experienced management staff directly involved from the onset of the project allows for maximum cost savings to be achieved.
