ABA NO.40I. INTRODUCTIONSCOPEThis report presents the Title I work performed in regard tothesite utilities distribution for the main building complex of the StanfordLinear Accelerator Center.Site utilities distribution is defined forthis project as distribution systems for domestic water, natural gas, sanitarysewers, hot and chilled water, compressed air for shop use and for heatingSLAC AHO 1991-012B14and air conditioning controls, cooling tower water, and low conductivitywater.Electrical utilities will be described in a subsequent Title Isubmittal whichwill include the underground telephone ducts.They areshown on drawing SK-03062-A for coordination with the "wet" utilities.FACILITIESThe site utilties have been routed along easements that are centrallylocated within the main building complex and do not interfere with futureexpansion sites.The buildings supplied include the Administration andEngineering BUilding, Cafeteria, Central and Test Laboratories, Shops Complex,ABA Construction Operations, Utility Building A, and heavy mechanical shop.Connections for future domestic water and sanitary sewers will be providedfor the accelerator-klystron housings, and future domestic water, sanitary. raand hot and chilled water for the Auditorium.- I -

. . a.tIII. BASIS OF IISIq!criteria studies and results of Title I work Desthe site utilities can be economical'-II .installed within centrally1 easements by a combination of the following modes of installation:a.Direct burialb.Covered pipe trenchThe costs considered in the site utilities study are those ofSLAC AHO 1991-012B14bringing the various systems to within 5 feet of the building limits.SITE AND FACILITY1. Site ConsiderationsDomestic water, natural gas, and telephone services enter theproperty from Sand Hill Road to the north.There are no excessive amountsof rrenching, back-filling, or grading required to install the systemswithin their easements as shown on drawing SK-03062-A.Advantage is takenof the natural site topography: the sanitary sewer outfall is routed through adatural depression in a north-easterly direction to Sand Hill Roaa as shown onSK-03062-B.At this point it will connect toa a new sewer main which theMenlo Park Sanitary District will install along Sand Hill Road to connect withtheir existing main at Santa Cruz Avenue.2.LayoutA rectangular layout of the site utilities evolved from a considerationof the building locations, requirementsfor expansion, and site topographyThe utilities easement approach has the dual advantages of less interferencewith other crafts during construction and assurance of location after constructionis finished.2 -

ABA NO.3.Methods of Installationa.Direct Burial-40Domestic water, sanitary sewers, natural gas, low conductivitywater, cooling tower water, hot water, and chilled water lines are buried withearth cover as indicated on drawing SK-03062-A.b.Covered Pipe TrenchesA covered concrete pipe trench will be installed from the northeastcorner of the Administration and Engineering Building to a point south of thesoutheast corner of Utility Building A.All "wet" utilities with exceptionof the sanitary sewers and water supply will be routed through this trench.SLAC AHO 1991-012B14The advantages of accessibility and maintenance are obvious, but theadditional advantages of an accessible underground route for future intercommunications between buildings is valuable.These requirements areindeterminate at this time, but it appears highly probable that increasing-------'L- - the Central Lab andintercommunication requirements will develo betweenthe A&E"Building.It is not advantageous to route electrical power cableswithin the utility trench.4.Functions of Independent Systemsa.Domestic WaterThe domestic water system furnishes waterf rdrinking, sanitation,fire protection (hydrants,.automatic sprinkler systems), and "make-up"water for the various closed systems( .g.cooling er,low conductivitywater, boilers, chillers).b.Cooling Tower WaterA -.,.rate cooling tower system is provided for use in the lowII . -.tel' Mat exchangers, compressors, chillers, test labIII." .- 3 -

ABA NO.A low conductwater system is provided for use in40trons,s, and other electronic equipment where extremely cleanmodulators,water is required.d.Hot and Chilled Circulating WaterCentralized bOiler and chiller installations are locateq inUtility Building A.Circulating hot and chilled water systems{l) furnishthe heating and cooling medium for air conditioning fan units in thebuildings as required.SLAC AHO 1991-012B14e.Compressed AirCompressed air is a utility on this project for shop use and foroperating temperature controls.It is piped from a centrally locatedcompressor station in Utility Building A along with the hot and chilled waterlines.f.Natural GasThere are two natural gas systems supplied. A firm or non-interruptibleservice is routed to the cafeteria.Ranges in the cafeteria thus have acontinuous supply af gas as specified by State of California PUC regulations.An interruptible service supplies the lab buildings and boilers in UtilityBuilding A.The boilers in Utility Building A will have electric ignitionfor gas or fuel oil, the alteenate fuel supply.g.Sanitary SewersSanitary sewers serve the project as indicated on drawing SK-03062-A.I.
