EXISTING DOOR FRA�tES <br /> f+ H <br /> C N <br /> �j o y A. NAC has proposed the use o( new rated doors in existing wood dcwr Gamcc at doors IeuJing into <br /> � ro r comdors. New doors in comdor wulls will receive new rnted door(rnmr.s. This solution was aceeptablu <br /> ,�, y �o the building o(ficials. <br /> N <br /> 5. COVGRGD ASSEM[3LY AREA <br /> p, A covered as.uumbly area is fonnul by a rcwf eztension to the east of the main 6uildine. This roof <br /> eztension ends more lhan 20 (eet from the annex building. A covzreil wal6lvay (rom the annez building <br /> ovedaps this roof exlension tu provide a coverr.�l passeSeway belween buildings. This combination of <br /> coverings neul nol be considered in lhe tolal area o(lhe 6uilding as �hey will be considercd n covered <br /> walk provided that �hey are of nomcombustiblo construction and are proviJed with siJe-wall mounleel <br /> spnnklzr hr.ads on cach building. If this coverul area is of combuslible mnswction,a dry pipe sprinkler <br /> system in the co�•ereJ area will be reyuirul. In eny case Ihe building sepurxtion muking the ennux a <br /> separale building (rom the nuin buildinb wili bz maintainul. Since Ihese areas are clussified us covered <br /> walkways, their area will not huve lo be cnlculnted in determining the over.dl arw of thn buildings to <br /> , which they are altachul. <br /> I� �� <br /> �� II. Tim Tyler will advise NAC if fire relardant Iro:ated wood is acceptable as a non-combustible material. <br /> This is prim�rily in rnference to lhe u.se o(firo retardant tri:ated wood shealhing for u roof deck in this <br /> 1 covzred area. <br /> __ <br /> ��� G. BOILGR ROOM <br /> , A, 77�e ezisting Fwiler room is made of conemle walls and deck, which constilute a onn hour eccupancy <br /> '�� xpur.�tion. <br /> I s 7, SPRINKLERING OF CLASS ROOM ARGAS <br /> '�.� p. NAC's building section through the clnss room wing was revieweJ. This seclion showeJ �hat u new <br /> �, � ceiling was being inslallul unJer lhe exisling combustible ceiling, thus crulling a dossroom spaca, a <br /> space ixlween the existing ceilinF and lhe new ceiline, and an attic space. 'fhe fire marshall indicated <br /> that if lhis wen; constructed as shown, sprinklzrs woulJ be nquired in ull lhree areas. A Jry sprinkler <br /> system would be reyuireel in the upper attic spacu sinca a dry head of(of a wet system would probably <br /> �, �1�� nol be able to give edequute covemgu to lhe large attic area. If Wo existing ceiling is removed, lhen only <br /> Uie arw ebove th�new ceiling,nnd the room itself wouid rcyuire sprinklering. <br /> i <br /> g, 7'he erra� ulwve the new ttiling in tl�e cortidors would reyuire sprinklering if the amount of combustible <br /> I ��1�� wiring expcsul in the cciling space excaxls the reyuircment of N.P.P.A. 7liis ussumes U�at lhe area <br /> � be�u�cen the existing ceiling md lhe new ceiling contains no combustible mat�rial. IP combustihlc <br /> � materiul is used in this area,sprinAlering will tw required ulwve this ceiling. <br /> C. One hour comdors can be provideJ in the existing builJing by covering the existing com6uslible ccilinb <br /> with one layer o( Sl8' typz X GWB. The existing cciling would not need to be rcmoved i( it were <br /> covercd wilh this nuderi:d. Tlie existing walls o(the corridors nrc finished wilh plaster which eztents all <br />
