Codes 2011 Ohio Building Code (based on IBC 2009), NEC 2009
Zoning R-2, Residential with Shared means of egress. This project will receive a full renovation to upgrade the building to today’s code and ADA-accessible standard.
Historical requirements Murphy Hall is the largest residence hall on John Carroll campus since it opened in 1964. Its original façade is mostly preserved throughout the years that it is recommended for nomination for the National Register of Historic Places.  For the nomination status to maintain, the façade would not be changed, including its fixtures, furnishings and material.  The university requires a lot split on this project for historic application and possible tax credits.  The new addition for the project will share similar architecture style on the façade to match the existing building.
The university wants a full update for Murphy Hall that will reduce the building maintenance cost significantly. This façade of the existing building is load baring masonry and stones. Being a 1964 building, the building does not have the envelope technology to become well insulated. One of the goals for this project is the replace the roofing with well-insulated and high-reflective material while maintain the asthetics, and to replace all the window with insulated glass and operable windows
Sustainability Features LEED certification will be the major sustainable feature for this project. The building interior system will be fully renovated to reduce energy usage throughout the building life cycle. While the shell of the building will remain the same aesthetic appearance, the renovation includes update of the roofing and window systems for a more thermo insulated system. The project considers sustainable solutions such as electronically controlled low-flow plumbing fixtures, rainwater collection for irrigation, recycled material and daylight harvesting.


Primary Engineering systems

Structural Murphy Hall is a renovation project where most of the structural system from the existing building structure is preserved. The existing floors are 6” to 8” thick slab on grade, with the existing walls construct out of CMU. The new structural component consist and not limited of W2.9xW2.9 welded wire fabric, HSS7, continuous Angles L2x2x1/4.

Mechanical Parts of the building, such as the social areas and bathroom are ventilated via central air-handling-units, others parts such as individual bedrooms utilize natural ventilation. The mechanicla ventilation includes 2 indoor chillers, rated at 100 tons cooling per chiller, and 4 condensers Electirical heaters are used to provide bathroom hot water.

Lighting Lighting system is driven to provide appropriate light level and more efficient energy usage. The building interior is lite with mostly good color rendering fluorescent, indirect wall mount fixture to account for low floor to ceiling height.  Where ceiling to floor height is appropriate for non-glare surface mount fixtures, fluorescent down-lights and sconce are used to promote a bright and open space. Each space has thoughtfully placed luminaires to avoid glare. Occupancy sensors are used to turn lights on/off when needed. The exterior is lite using energy LED and CMH surface mount luminaires at building exits and needed perimeter.  

Electrical Electrical power is supply by John Carroll University’s campus utility medium voltage system. The utility supply at the building at a one indoor surface mount, dead-front Single-ended1600A 480/277V transformer. From this the power is routed through a main switchboard and another level of main distribution before going to the designated area branch panel  The different branch panels supplies building at both 480/277V and 208/120V. Where voltage is different, transformer sized accordingly is provided.

Constructions This project is constrained to fit within an academic year, or 14 months from start to finish. The scope includes interior and some exterior demolition, re-construct all of the electrical and mechanical system, restore the building façade and roofing.  There will be 3 staging areas on the open landscaping area surrounding the building.
