Project Highlights

Norwalk Police Headquarters in Norwalk, CT
This new 60,000 sq. ft. structure houses the city's police offices, detention cells, an indoor-firing range, administrative offices, and a state-of-the-art communications center to handle regional emergencies. Mr. Preston worked closely with the project's architect city and police officials and contractors to design structural elements of the building to double as part of the security system. Mr. Preston was the project manager for the police headquarters while with the DiSalvo Ericson Group.

St. Mary's Parish School Gymnasium Addition in Ridgefield, CT
This 16,000 sq. ft. masonry, concrete, steel and glass addition provides an eye-catching multi-use space for the growing school. Mr. Preston exercised his creativity and innovativeness in designing the multi-directional double-cantilevered roof system. Working closely with the geotechnical engineer, Mr. Preston designed the foundation system designed to resist not only normal building loads but also considerable upward hydrostatic pressures due to the site's high water table. Working together with the project architect, exposed steel connections were designed to blend aesthetic appeal and function. Mr. Preston was the project manager for the gymnasium wing addition while with the DiSalvo Ericson Group.

Long Ridge School Arts & Athletics Wing Addition in Stamford, CT
Accentuated by steel tube trusses and glulam beams and trusses, much of this 13,000 sq. ft. addition remains exposed to view, providing an open and natural feel for the school's students.
