DUSEL Development Process: The Roadmap from Science & Engineering Plan to the Facility Description

1. DUSEL Development Process:The Roadmap from Science & Engineering Plan to the Facility Description Lee Petersen, CNA Consulting Engineers Dale Holland, Dunham Associates Greg Hulne, Miller-Dunwiddie Architects

2. Motivation • Science/Engineering Program  Cost • Input to Site Advocates • Framework for Modularization • Framework for Site Evaluation CNA - DA - MDA

3. Motivation: Science/Eng  Cost CNA - DA - MDA

4. Topics • What is infrastructure? • Short-term roadmap (design process) • Infrastructure matrices • High-level design criteria • Design codes & the implications • Next steps CNA - DA - MDA

5. What is “infrastructure”? • Traditional definition: • Grouping of science & engineering functions into modules • Sequence, expansion, reuse • Excavations, systems & services to support science • Design must satisfy fire & life safety codes • But “infrastructure” also includes: • Site characteristics necessary for conducting the science & engineering program • Rationale for depth, rock type, stress, groundwater, etc. CNA - DA - MDA

6. DUSEL Development Sequence • Develop Science & Engineering Research Plan • Collect Technical Requirements • Design criteria • Site character, grouping, sequence & infrastructure) • Timeline issues • Relationship Matrix • Illustrates compatibilities and incompatibilities • Relationship Diagramming • Illustrates spatial relationships CNA - DA - MDA

7. HLDC in the Design Pyramid CNA - DA - MDA

8. DUSEL Design Criteria • Science Design Criteria • Public Access • Occupancy • Codes & Standards • General Access • Schedule • Experiment Isolation CNA - DA - MDA

9. Infrastructure for Physics CNA - DA - MDA

10. Infrastructure for Earth Science CNA - DA - MDA

11. Site Characteristics-Earth Science CNA - DA - MDA

12. Site Characteristics-Earth Science CNA - DA - MDA

13. Relationship Matrix CNA - DA - MDA

14. Timeline Issues • Sequence, expansion, remodeling • Characterization • Necessary for design • Integration with Geo & Bio science program • Shared or single purpose caverns • Funding profile • Shared use of accessways • Experiment operations & new construction • Hazardous materials & life safety CNA - DA - MDA

15. Fire & Life Safety Codes • Role of FLS codes in design • Code environment (past, present, future) • Code applicability • Basic code requirements • Implications • Key first steps for sites • Issues to be resolved CNA - DA - MDA

16. Role of FLS codes in design • Codes represent the aggregate knowledge of the industry • Codes are a starting point, but don’t cover special hazards • Codes: • Are national standards • Are minimum requirements • Are statutory • Impact layout & concept • Code variances occur, but are jurisdiction-specific CNA - DA - MDA

17. Codes • Prior or current codes: • Uniform Building Code • Uniform Fire Code • Uniform Mechanical Code • Current or Future codes: • International Building Code • International Fire Code • International Mechanical Code • National Fire Protection Assoc. • Highway Tunnel Codes • Mine Safety & Health Admin Codes • OSHA • ADA CNA - DA - MDA

18. Example of some changes from UBC to IBC • Air changes per hour • Was 8 ach, now 6 ach • Compartmentalization • Was 1 compartment, now minimum 2 • Fire separation • Was 2 hr, now 1 hr • Independent air supply systems • Was central system, now compartmentalized CNA - DA - MDA

19. Current Code Environment • California: ???? IBC • Colorado: 1997/1991 UBC • Minnesota: 2000 IBC • New Mexico: 2003 IBC • South Dakota: ???? IBC • Virginia: 2000 IBC • Washington: 2003 IBC CNA - DA - MDA

20. Preliminary applicability CNA - DA - MDA

21. Role of the Local Code Official • Identify Authority Having Jurisdiction (AHJ) • Academic institution • City • County • State • DUSEL-like facilities are outside the experience of most AHJs CNA - DA - MDA

22. Minimum Requirements • Construction materials • The underground portion of the building shall be of Type I construction. (3) • Hazard requirements • Building use hazards • Egress • Smokeproof enclosures • Exit Ventilation • Areas of Refuge (3) IBC Section 405.2 CNA - DA - MDA

23. Minimum Requirements • Smoke ventilation • Compartmentalization • Smoke Venting Systems • Alarm Systems • Fire Protection • Sprinklers • Standpipes • Fire Alarm • Smoke Detection • Alarm System CNA - DA - MDA

24. Minimum Requirements • Power systems • Standby Power • Emergency Power • Emergency Illumination CNA - DA - MDA

25. Issues to Resolve • Egress & refuge • Cryogen & other hazards • Requires special treatment • Fire hazards • Integration of diverse codes at diverse sites • Building • MSHA • Highway tunnel CNA - DA - MDA

26. Critical next steps • Develop Science & Engineering Research Plan • Collect Technical Requirements • Design criteria • Site character, grouping, sequence & infrastructure) • Timeline issues • Relationship Matrix • Illustrates compatibilities and incompatibilities • Relationship Diagramming • Illustrates spatial relationships CNA - DA - MDA

27. Motivation (review) • Science/Engineering Program  Cost • Input to Site Advocates • Framework for Modularization • Framework for Site Evaluation CNA - DA - MDA
