Overview of Space Assessment • Data sources and definitions • Age and general rating of buildings and trailers • Space use and condition index • Seismic evaluation • Summary
Data Sources • Facilities Information Management System (FIMS) – database for real property management (buildings, trailers, other structures and facilities, land): gross square footage; summary condition; no room-by-room information. • SLAC Building Information – database for space management: room by room information (office, lab, etc.) • 10-Year Site Plan (FY2008- FY2017, June 13, 2006) • Earthquake safety (Seismic Evaluation Committee report)
Definitions (1 of 3) • Property Types (FIMS): • BUILDING: A building is a roofed permanent structure suitable for housing people, materials, or equipment. A building must have as a minimum, a roof, four enclosure walls and a floor. • TRAILERS and MODULARS: • Trailer – a factory built assembly with a roof, four walls, and a floor designed to be hauled or pulled on the public roadways (single-wide). • Modular Building – a site assembled building constructed of two or more joined factory-built standardized units. Modular buildings are sometimes described as single-wide trailers (approximately 12 feet wide) joined together as a single unit. • When installed so they are permanently affixed and cannot be relocated without being dismantled, or have been modified in such a manner as to meet the criteria for real property, they are considered real property and are included in FIMS using Asset Type 501, Building.At SLAC, all double-wide and greater trailers are defined as Buildings unless classified as temporary (to be in place for a period not-to-exceed five years). • OTHER STRUCTURES AND FACILITIES: any fixed real property improvements to land that are not classified as a building, modular building, or trailer, including bridges, towers, roads, fences, and site utility systems. Utility shelters that do not satisfy the definition of “building” or “shed” fall into this category. • CONTAINER (Cargo) – a rigid box, originally designed for the shipment of goods, generally used for the storage of materials and supplies.
Definitions (2 of 3) • FIMS rating scale for buildings & trailers is as follows: • Excellent: Deferred maintenance is <2% of replacement plant value. • Good: Deferred maintenance is 2 - <5% of replacement plant value. • Adequate: Deferred maintenance is 5 - <10% of replacement plant value. • Fair: Deferred maintenance is 10 - <25% of replacement plant value. • Poor: Major deferred maintenance is 25 - <60% of replacement value.
Definitions (3 of 3) • Categories of Space: • EQUIPMENT: CONTROL, EQUIPMENT, HVAC, UTILITY • LAB: LABS AND CLEAN ROOM, • MEETING: CONFERENCE ROOMS • OFFICE: OFFICES • SHOP: ASSEMBLY, FAB, MACHINE SHOP, MAINTENANCE SHOP, GENERAL, MATERIALS, VEHICLE REPAIR • STORAGE: WASTE STORAGE, CHEMICAL STORAGE, EQUIPMENT STORAGE, FILE STORAGE, MISC STORAGE, PARTS STORAGE, RAW MATERIALS STORAGE • SUPPORT: BREAK/COFFEE, COMPUTER, COPY/FAX, CORRIDOR, LIBRARY, MAIL, PRINT/PLOT, REST ROOMS • OTHER: OTHER, UNKNOWN

Seismic Data • 1996-1998: Seismic Survey in response to Executive Order 12941 • Included in the survey were: buildings with significant population; environmentally sensitive buildings; buildings with large floor area and crane coverage. • Earthquake design standards based on 1994 Uniform Building Code, with substitution of more stringent SLAC-specific values and adoption of performance-based design description from the Structural Engineers Association of California (1995) • Assessments conducted with the help of structural engineering consultants • Adoption of new SLAC Seismic Design Specifications
Seismic Ratings • Ability to withstand 7.0 to 7.5 magnitude earthquakes Based on Structural Engineers Association of California - Vision 2000
Seismic Assessment • Rating of 5 or above after repairs: 97% of surveyed structures (in sq. ft.) • Rating below 5: 3%of surveyed structures (in sq. ft.)
Summary • Aging facility (2/3 of the buildings and trailers are over 30 years old) • Buildings are in good condition (Deferred maintenance is <5% of replacement plant value on average) • Trailers are in adequate conditions (Deferred maintenance is 5 - <10% of replacement plant value on average) • 90% of lab space is in buildings in the “adequate or better” category • 37% of office space and 39% of shop space are in buildings in the “fair or below” category • Most major buildings rated 5 (safe) or better in their ability to withstand a major earthquake.
