INTRODUCTION

OHSU strives to create a quality environment for all users of its facilities.

With the intention of clearly and concisely communicating our standards, including preferences and recommendations to the team of Consultants and Contractors who work on our projects, we composed these Engineering Standards. The work involved in the creation of this document comprised obtaining information from stakeholders on campus, including the professionals who manage OHSU’s daily campus and maintenance activities, as well as the leaders who define OHSU’s strategic approach and future vision. Their expertise, experience, ideas, and recommendations, in addition to our own knowledge of best design and construction practices, are incorporated into this document to guide and assist campus design efforts.

The OHSU Engineering Standards are divided into sections that follow the Construction Specifications Institute (CSI) standards. This format facilitates the use and familiarity by the design and construction professionals. The standards in this document focus on creating and maintaining OHSU buildings with the following characteristics:

• OHSU buildings will be repurposed for uses other than those identified at the time of their original design. Building components and systems shall be designed to allow for changes in purpose, function and occupancy.

• OHSU Buildings and components shall be designed to be accessible and for ease of maintenance.

• OHSU is a place of healing and safety. Toxic, odors, and hazardous materials shall be minimized or eliminated from construction materials and components whenever possible.

Appendix G – TENANT NOTIFICATION LETTER Leased Space: Tenant Notification

Tenant Notification Letter

Dear <<xyz>>

Oregon Occupational Safety and Health Administration (OR-OSHA) regulations require building owners to notify tenants that asbestos-containing materials were found within the tenant space. OR-OSHA rules require you, in turn, to notify your on-site employees of this information and to provide your maintenance staff with certain levels of training. This requirement also extends to any other employers whom you may hire to perform duties in proximity to asbestos containing (ACMs) or presumed asbestos containing building materials (PACMs). An inventory of the ACMs identified is listed below:

Type Location Quantity

These materials are currently in good condition; however, impact or damage could result in the release of asbestos fibers. Also, OHSU cannot and does not warrant that all ACMs and PACMs have been discovered and documented for your leased area(s). You are required to notify us in advance if you plan any activities which may disturb them, or if you discover any damage or disturbance to these materials. OHSU has the responsibility for managing asbestos in your leasehold and will do so as appropriate and in compliance with applicable law and regulation.

If you have specific questions regarding this correspondence, please direct your questions and comments to (Property Manager) at (phone).




Appendix H – NIH BIOSAFETY LEVEL 3 LABORATORY CERTIFICATION REQUIREMENTS National Institutes of Health (NIH) Biosafety Level 3 Laboratory Certification Requirements By: Deborah E. Wilson, DrPH, CBSP Farhad Memarzadeh, Ph.D., P.E. July 2006 Biosafety Level 3 (BSL-3/ABSL-3) containment laboratories for animals and research are the most difficult containment level facilities to design and operate. They should be certified for use before initial operation and subsequently on an annual schedule or after a program change, renovation or replacement of critical HVAC/exhaust system components (specifically fans, air valves, or fan motors) that may affect the operating environment of the laboratory. Laboratory certification is the systematic review of all safety features and processes associated with the laboratory (engineering controls, personal protective equipment, building and system integrity, standard operating procedures (SOPs) and administrative controls such as documentation and record retention systems). This validation assures that all reasonable facility controls and prudent practices are in place to minimize, to the greatest extent possible, the risks associated with laboratory operations and the use of biohazardous materials. Standardization of an initial and annual certification process for BSL-3 facilities will provide accountability that ensures proper and regular maintenance and demonstrates the use of SOPs that protect human and animal occupants, the environment and the research integrity. High containment laboratory certification helps ensure that:

• Appropriate site and protocol specific administrative controls and proper engineering controls are being used

• Personal protective equipment (PPE) is appropriate and undergoes regular inspection to maintain personal safety

for the tasks being performed

• Decontamination systems for waste and other potentially infectious materials, including spill management, has been

adequately considered and proper procedures are in place to mitigate environmental and personnel contamination

• Proper standard operating procedures (SOPs) for general laboratory safety and security, including physical,

electrical, biological and chemical control mechanisms are in place.

Certification of high containment laboratories will be performed by a team of professionals with experience and credentials in engineering and biosafety/occupational safety and health. DOHS will manage and perform certification of NIH intramural laboratories and other high containment facilities. When appropriate, DOHS may delegate the responsibility for providing certification of a laboratory or facility to a third party. As a part of the laboratory certification process, the Biocontainment Laboratory Certification Checklist must be completed as a retained record document. Re-certification of the facility will be performed on an annual basis, as a minimum. A comparison should be made to the baseline established during initial certification. Detailed records of the certification process and test results must be maintained to provide an accurate operations history of the laboratory.




Appendix I – ALARM VERIFICATION i. Where sprinkler is present:

1. In the event a smoke detection device indicates an alarm state, the Alarm Verification Feature shall prevent the alarm state from initiating alarm functions.

2. In the event two or more smoke detection devices indicate an alarm state within one minute the Alarm verification Feature shall not prevent the alarm state from initiating alarm functions.

3. In the event a non-smoke detection device, such as heat detection device or waterflow device, indicates an alarm state, the Alarm verification Feature shall not prevent the alarm state from initiating alarm functions.

4. At no time shall the Alarm Verification Feature prevent an alarm state from initiating alarm functions for more than one minute.

ii. The Alarm Verification Feature shall not be applied to the following devices. 1. Heat detection devices 2. Duct detection devices 3. VESDA systems 4. Manual fire alarm pull stations 5. Waterflow devices 6. Any alarm initiating device not designed for smoke detection

iii. The Alarm Verification Feature shall be applied in the following spaces. 1. Public and staff restrooms 2. Kitchen spaces 3. Corridors and hallways with multiple smoke detectors within same smoke compartment

iv. The Alarm Verification Feature shall not be applied in the following spaces. 1. Rooms where patients may be unattended while sleeping, unconscious or sedated 2. Operating rooms 3. On-call rooms 4. Locations protected by VESDA type smoke detection 5. Any space or smoke compartment protected by only one smoke detector

v. The Alarm Verification Feature shall be applied to all spaces on Marquam Hill campus unless otherwise limited by this standard. The Alarm Verification Feature shall not be applied to OHSU facilities not located on Marquam Hill campus.
