THE BOROUGH OF SEWICKLEY WASTEWATER TREATMENT PLANT
HEADWORKS & DEWATERING FACILITIES

The Borough of Sewickley sought to expand upon their existing wastewater treatment capacity, while at the same time upgrading and replacing the existing equipment and facility.  These necessary expansions and upgrades resulted in the construction of new headworks and dewatering buildings on their existing property, housing new degritting, dewatering, conveyor and pumping equipment.  Additionally, the existing laboratory and dewatering structure have been renovated to upgrade the laboratory environment, expand the break room and locker room facilities and house the SCADA system and main power distribution equipment. 

These new and existing facilities required D & D Engineering to design a redundant electrical service to ensure minimal power interruption,  power distribution throughout the site, a lighting system that includes explosionproof lighting within Class 1, Division I spaces and exterior lighting that is sensitive to the surrounding neighborhood,  access control and surveillance systems, controls and communications and a SCADA system that incorporates inputs from equipment and monitoring systems throughout the facilities. 

Professional services for this project occurred in 2009.  Construction has been ongoing since late 2009 with a scheduled completion date in mid-2011.  The electrical construction cost for this project was approximately $500,000.

NORTHSIDE INSTITUTIONAL CHURCH OF GOD IN CHRIST, PITTSBURGH, PA

The congregation of the Northside Institutional Church commissioned Tusick & Associates Architects to design a new church to be building on the site of their previous church facility.  This new facility includes a 5,500 square foot worship space, parish offices, classrooms and a multi-purpose center with a full-service kitchen for parish events and activities.

D & D Engineering, working closely with the architect and civil site engineers, designed the power, lighting, fire alarm and communications for the new church.  The lighting design included the illumination of several architectural features include interior and exterior crosses, coves and a chancel space used for conducting services, choir performances and presentations.  A cost conscious, basic theatrical lighting control system was provided for the worship and chancel space.  The worship space lighting was achieved with decorative ecclesiastical chandelier and sconce fixtures with custom lamping, as necessary to meet the local energy codes.  Energy-efficient, high-bay fluorescent fixtures were used to provide multiple level lighting within the multi-purpose room, to meet the functional requirements of events ranging from basketball games to community dinners and presentations. 

Professional design services for this project occurred in 2009.   Site construction has begun and the facility remains under-construction, a construction completion date has not been determined.
