Provided Mechanical, Electrical and Structural Engineering services for the replacement of fourteen gas fired rooftop air conditioning units serving various areas (including the administration area, dining areas, kitchen, new store and other public areas) of the Baysox stadium which is a multipurpose sports venue and is primarily used for baseball.

Extensive field work was performed to determine the locations and sizes of the existing supply and return ductwork through the roof in coordination with the supply air outlets and return air inlets locations/dimensions of the new rooftop air conditioning units. Some of the mew rooftop units were located on raised structural steel platforms to allow for the transition of the supply/return ductwork. Other rooftop units were converted to the horizontal supply/return air discharges to allow for transition of related ductwork prior to connection to the existing supply/return ductwork above the roof.

The power to the new rooftop units was shown to be provided from the existing electrical panel boards located in the two electrical rooms. The structural steel platforms supported from the existing roof framing, were designed for the new rooftop units which were raised above the roof level. The supports of the roof curbs from the existing roof framing were designed for rooftop units with horizontal supply/return air discharges.

Our scope of work also included preparation of construction documents for the replacement of the site lighting serving all of the parking lots and the walkway serving the stadium. Several versions of the lighting calculations for the parking lots and walkway were prepared for the owner’s/user’s review. The structural drawings included the design of the foundations for the light poles.
