Based on many experiences, the last minute little changes from one discipline cause large issues for another discipline. The plumbing drawings should reflect the clear scope of work and the application of separate systems on their own drawings will provide better definition of the intended work. Examples of this are as follows: Sheet Number: P001 P002 P100 P201 P202 P301 P401 P501 P601 Sheet Description: Plumbing Title Sheet, Drawing Index Plumbing Schedules, Notes, Water Calculations Site Plan – Plumbing 1 st Floor Plan – Plumbing and Medical Gas Plans 2 nd Floor Plan – Plumbing and Medical Gas Plans Enlarged Floor Plans - Plumbing Piping Diagrams Details Controls 3.12 Best Practices for Electrical Drawings Electrical Documentation Purpose The purpose of the Electrical Drawings are intended to depict all electrical devices & components required to provide safe, reliable electrical systems. Based upon the current trend in healthcare environments for new medical and surgical procedures that are constantly changing, a greater emphasis is needed for expandable electrical systems. Content Based upon the complexity and scale of the project, the information provided on the electrical drawings should show clear description of the work required for the project. In many cases, the project may involve the documentation of existing electrical systems and should clearly identify new versus existing devices and equipment. The need for modern digital communication systems will also require clear documentation of these systems as they relate to the critical systems within the facility. These systems are presently reviewed only for routing as it pertains to fire rated wall penetrations. The title page should clearly define the project location and vicinity by graphical means. The applicable building codes should be stated. A drawing index is recommended to clearly identify all the unique systems that may be involved. (OSHPD Best Practices) Page 52 DRAFT FINAL, Sept. 2011

Several drawings contain essential information such as Load Calculations, One-Line Diagrams, Panel Schedules and drawing details. These documents usually follow the physical device locations placed on the floor plans. Checklist of Key Items: 1. All electrical plans and specifications signed by the electrical engineer of record. 2. List of symbols and abbreviations used on plans and their meaning. 3. Correct electrical code version cited. 4. Room names and numbers on all plan sheets. 5. Provide wall fire ratings & legend. 6. Single line diagram of the electrical system showing normal source and segregation of the essential electrical system. Clearly identify components as normal, critical, life safety, or equipment. 7. Site plan showing service entrance, distribution system, service transformer, and generator location. 8. Drawings showing details of all switchboards, panels, and equipment. 9. Load calculations or other approved methods showing verification of load capacity for all equipment and conductors. Show effect on both normal and emergency system. 10. Panel schedules with totalized, tabulated loads. Panel schedules shall indicate rating of panel, feeder conductor, feeder overcurrent protective device, branch/system (critical, life safety, equipment) and loads served. 11. Clearly indicate the AIC ratings of all panelboards & distribution boards. 12. Schedules of ratings of equipment requiring electrical connection. 13. Schedule showing all feeders phase and ground conductors, conduit sizes, estimated lengths, and overcurrent protective devices. 14. Location and power source for all wiring devices, including receptacles, lights, switches, junction boxes, power outlets, and telephone outlets. 15. Fire alarm system. Provide specifications for equipment, show location of all devices, and show connection to life safety power source. Indicate if power limited. 16. Nurse call system. Provide specifications for equipment, show location of all devices, and show connection to power source. Indicate if power limited. 17. All equipment must be listed, labeled, or certified by a Nationally Recognized Testing Laboratory including X-ray and diagnostic equipment. (OSHPD Best Practices) Page 53 DRAFT FINAL, Sept. 2011

Electrical Documentation<br />

Purpose<br />

The purpose <strong>of</strong> the Electrical Drawings are intended to depict all electrical devices & components<br />

required to provide safe, reliable electrical systems. Based upon the current trend in healthcare<br />

environments <strong>for</strong> new medical <strong>and</strong> surgical procedures that are constantly changing, a greater<br />

emphasis is needed <strong>for</strong> exp<strong>and</strong>able electrical systems.<br />

Content<br />

Based upon the complexity <strong>and</strong> scale <strong>of</strong> the project, the in<strong>for</strong>mation provided on the electrical<br />

drawings should show clear description <strong>of</strong> the work required <strong>for</strong> the project. In many cases, the<br />

project may involve the documentation <strong>of</strong> existing electrical systems <strong>and</strong> should clearly identify<br />

new versus existing devices <strong>and</strong> equipment.<br />

The need <strong>for</strong> modern digital communication systems will also require clear documentation <strong>of</strong><br />

these systems as they relate to the critical systems within the facility. These systems are<br />

presently reviewed only <strong>for</strong> routing as it pertains to fire rated wall penetrations.<br />

The title page should clearly define the project location <strong>and</strong> vicinity by graphical means. The<br />

applicable building codes should be stated. A drawing index is recommended to clearly identify all<br />

the unique systems that may be involved.<br />
