01 30 00 ADMINISTRATIVE REQUIREMENTS

01 35 13 Special Project Requirements

.01 General
  1. This manual of Design and Construction Standards has been prepared by the University to guide Architects and Engineers, hereinafter referred to as the Professional, commissioned to design buildings and other facilities for The Pennsylvania State University.  The information contained herein applies to the University Park Campus and all other Campuses; The Milton S. Hershey Medical Center (MSHMC); and all other locations.
  2. Due to Penn State's size and breadth of operations, many locations have unique operating characteristics and requirements, which must be incorporated into the project by the Professional during design.

.02 Projects at the Milton S. Hershey Medical Center
  1. As a fully functioning healthcare institution, the Milton S. Hershey Medical Center occupies a unique position within the University system, and therefore has many requirements and regulations that do not apply to other University locations.  The Professional must coordinate all project requirements with the Office of Physical Plant HMC Design and Construction Division, and with MSHMC Facilities Planning & Construction Department.
  2. All construction firms performing work at the Milton S. Hershey Medical Center must have their project managers and superintendents ASHE Healthcare Construction Certified.
  3. In addition, the following documents describe specific requirements that apply only to projects at MSHMC.  Where these documents conflict with other requirements in the Design & Construction Standards, these documents supersede other requirements:

01 35 20 Safety Requirements

.01 General Safety Considerations
  1. Runaways and ramps should be installed in all buildings where bulk supplies are handled.  Ramps should have a surface providing traction.
  2. All glass and glazed doors used at entrances, stairwells, etc., shall have adequate push plates or bars and proper glass as required by applicable building codes or regulations.
  3. All windows in buildings (above ground floor) must be of the type which can be washed on both sides from the inside of the building.  Where construction is such that this type of window cannot be installed, there shall be safety belt anchors placed at the outside of the windows for fastening safety belts and an outside ledge for standing not less than 12" wide.  Safety belt anchors installed outside shall be a standard approved type. They shall not be the expansion bolt type.
  4. On all windows where the stool of the window is less than two feet from the floor, there shall be bars or other approved means provided to eliminate the possibility of falls through the windows. Casement windows or other outward projecting sash will not be used at the ground floor.
  5. A non-slip nosing shall be installed on all interior stairs. Nosings with grooves or other depressions tending to form trip hazards shall not be permitted. (Carborundum or similar abrasives are not permitted.)
  6. All outside steps must be adequately lighted  Treads and landings should have positive drainage away from the building.
  7. Suitable and guards shall be provided at all places such as stairwells, outside steps, bridges, loading ramps, etc. where persons are exposed to the possibility of falls from one level to another.
  8. All inside lighting fixtures must be placed so relamping can be accomplished with minimum effort and hazard.
  9. Chemical and flammable liquid storage and usage areas will be ventilated sufficiently to remove all fumes and shall be constructed in accord with all applicable codes and University requirements.
  10. For the University piping color code and the usual painting called for under the mechanical trades, the University uses a "Color Code" for the identification of certain equipmentment and piping. See Division 23.

.02 Roof Fall Protection and Prevention
  1. Purpose
    1. The Pennsylvania State University Office of Physical Plant, in its continued dedication to safety, has developed the following minimum standards to improve fall protection and prevention through proper planning, design, construction and maintenance. These standards are intended to remove fall hazards, prevent access to fall hazards, restrict movement at fall hazards and/or provide the proper fall arrest equipment as well as assist in the proper selection, care and use of fall protection equipment.
  2. Definitions
    1. Fall Protection Team – The Pennsylvania State University Office of Physical Plant has established a team of individuals including members of the Safety, Design Services, Campus Planning and Design, Work Control Center, Maintenance Programs, Roof Crew, Project Management Offices and Commonwealth Services to establish, maintain and uphold Fall Protection and Prevention Standards.
      1.  At a minimum this team will meet to review all roof fall protection risk assessment priorities (typically budgeted for annually) (see section 5. g.) buildings during the preliminary design for concurrence on fall protection scope and approach.
    2. Fall Hazard – A distance of 4 feet or more to the next lower level.
    3. Feasible – Relates to these factors:  cost justification (installation cost, training, personal fall arrest equipment cost, inspection cost, etc), status of personnel utilizing structure (employee, student, public, etc), structural capabilities, and aesthetics.  Final determination made by the Fall Protection Team.
    4. Passive Fall Protection Systems - A “passive” fall protection system refers to a system that is non-dynamic, stationary, and does not move, adapt, or change when in or out of use. Passive systems do not require the use of personal protective equipment or active participation from individuals occupying the roof.  Common Passive systems on campus include parapets and guardrails.
    5. Active Fall Protection Systems - Active fall protection systems are dynamic and require the use of special personal protective equipment, training, as well as active participation by the individual.  Common Active systems on campus include Life Lines and Anchor Points.
    6. Serviceable Equipment: Means such equipment requiring servicing from the roof level as solar array/structure, HVAC, fan units, exhaust units, air handler.  The roof surface, floor drains, gutters, cameras/security cameras, antennas, cell towers and equipment on the roof that can be entirely serviced from beneath the roof level, are not considered serviceable equipment.
    7. Path of Travel:  Examples include, but are not limited to, pavers/pads/matting that designate a path, roof access location in relation to serviceable equipment location, and the logical walking path a person would take to get from a piece of serviceable equipment to another.
  3. Applicability
    1. Any project which proposes to add, remove or modify any portion of the roofing system or roof-top equipment, including new construction.
      1. Old Main Building is excluded from the requirements of this design standard, fall protection methods will be determined by the Fall Protection Team
  4. Roof Fall Protection Codes and Regulations
