f) Walls between living units and between living units and corridors, and exterior walls of living units should have a sound transmission class (STC) of at least STC 50.
g) Floor and ceiling assemblies should be at least STC
55 and have an impact isolation class of at least impact
insulation class (IIC) 60. Telephone, cable television,
convenience outlets, and mechanical ducts should not compromise
the acoustical integrity of wall, floor, or ceiling assemblies.
Select fluorescent lamp ballasts to minimize noise generation.
4.31 Structural Selection. Recognize that housing are modular and repetitive in nature; therefore, decisions concerning the structural system have substantial affect on construction costs. Coordinate column spacing and layout with the building's floor plan so that they occur within or in alignment with walls. Hold columns occurring within spaces to a minimum and limit them to larger public spaces such as the laundry room. Analyze the proposed structural system that is the most economical method of realizing the architectural design intent. Select an economical structural system based on:
a) Facility size
b) Projected load requirements c) Subsoil conditions
d) Local availability of materials and labor e) Feasibility of prefabrication
f) Local construction practices
g) Resistance to fire, wind, snow, seismic, geologic, and permafrost conditions
4.31.1 Vapor Barriers. Calculate vapor permeability and temperature through the entire wall sections including interior finishes to ensure dew point does not occur within the wall system. Special construction considerations not limited to heating, ventilating, and air conditioning (HVAC) systems are required in humid areas.
4.31.2 Roof Systems. Design and detail roof systems to resist maximum wind for the area. Provide a residential character through the use of gable or similar sloped forms.
