Sine* about I960, however, there haa been a drastic changei th* use et load pad* baa increased by a factor of tan. And, surprisingly, nearly all thi* lncreae# ha* been for baild1.ru foundation*. As I aaa It, than bam bean tbraa reason* for thlst First, with no disrespect for tha arobitacta and engineers of, sey, thraa decade* ago, building* today are engineered to use their structural auAerlal far nor* effectively than those of tba 30'*. Consider the differaeo In weight between two office building*, one of conventional naeonry facing and the other with sheet natal curtain walic. Jhls dlffarenoa In natslvnnaaa alone probably ha* a great deal to do with the way a building will react to vibration. Xou can aaa that Wan building* are designed to tight engineering standards, with no safety factors of tan, the use of vibrstico pads becomes a reasonable part of th* mylneerlag. Second, the promotional activity mdsrtaksn by th* Lead Industrie* Aeeoo., Amo the current build!boon In Rev Tbrk got \mder way, has bad a traoaahla direct effect. In case after oae* I have fouod that the engineer* and architect* with them Z work first leaned of lead-asbestos pads through th* advertising and publicity effort* of UA. lb* third factor 1* somewhat acre subtle. We are well Into a period tdmrs big lob* are don* by orginiiatiorM, frequently big organlaatlon*. to* nan 1* seldon given th* credit for designing or building any of th* hug* office building* or other facilities now undertaken. But one nao any still be singled cut for Infscy If there Is any failure. Picture the plight of the poor engineer tfco la afeonlabed not to spend a oent tnneoeesarily, end who will get no glory for a lob well done -- but \ho way be looking for a job tar th* next five year* if th* building doe n't oooe up to expectations. The existence of the abundance of successful case histories of th* os* of pad*, publicised by ill, put* thi* poor fellow In th* position of using th* pad* aa ineurence. And frankly, there Is no deception Intended by us, and, Z think, non* practiced. She case histories are eucceea etorie*! Lead-asbestos pads are pretty cheap insurance, too. In any of tb* new building* using than, th*y add about a tenth of one per cent to the oest of the building. Z should point out that so** of th* engineers and architects X*v* worked with are not "ooeroecT into using pads.

Proa your own experience with selling, you may recognise th* situation* Thi* le another plaoe there the existence of a non-profit organisation Ilk* LXA proves valuable to m aa a nanufactuier of lead product* and to yoo aa lead producers, in working with your people Z oan't really eey Z find then Inertial or disinterested where lead Is uoncenwd, but they do represent a step In that direction to the customer who oist always suspect that ny naj& aev* may be to reach for a contract or order book. yirjqw ujJSjWjjjP iBkpjBBPHff LIA15598 Prtncis tUnin -4- lead Tersua Tibrstiobi A Sutssary and Outlook took St 04MI Ilka tbssot About s year ago, the architect for the Seminole Mworial Hospital la Smford, Florida inquired about pads for uss inAr a rooftop cooling tower.

Ed supplied tbs Information and Insight bs needed. today tbs codling tower la Dinted on lead pada.

Ed Martin visited both tbs Health Department and tbs City Engineers in Hew fork to arrive at a suit able pad arrangement for the new City Health Center there del 1 rata laboratory instilments must be protected frem vibrations caused by truck traffic. Currently, Ed, Bruce, and Dave are all working on the new studio being erected in Manhattan for tbs Columbia Broadcasting Syateau In tha last lssua of LEAD you nay have notioed a story about the uss of pads at Motel City la Hew Tork. This is a particularly interacting omss involving the use of air rights, lbs unique motel, with its own garages and racraational facilities is built over the main freight trackage of the Hew Zork Central on tha west aids of Manhattan. Ed Martin was la on this project in the early stagee. He talked to tbs builders shout lead for pools and flashing as wall as pada. I would like to quote frtn a broadcast by Jack Walters of radio station VCB3 mads last Dececber. Mr. Walters is speaking of the builder of Motel City, Mr. Budiah . . . 'Wotel City had begin as soneone site's enterprise . . , and bs (Kr. Budlsh) stepped in after they were about to give up on tha project. Cr of the big haaarda was in Aligning a pisoe in that particular air space directly over the Hew Xork Central Railroad, and in keeping out traffic sound." Later in the broadcast the occmentctor said, "The entire building floats cn a lead and asbestos foundation, Kr. Budiah told me, and this absorbs virtually all outside sound. Klnety par cent of the noise in a city, be said, thich reache* the inside of a building, It the result of ground-borne vibration. So even though the sctal is located directly over a railroad, and giant trailer trucks roar by out si A just before they enter the Lincoln Timel, tha entrance to ihlch can bs seen from tbs motsl, tbs building is --i<giy quiet." Haturally, most of our jobs are handled without any direct action by LZA. But even here we make extensive use of the literature available through tha O association. And a gratifying portion of our business today la direct inquiryproof that engineers and architects are reading tha advertising and publicity about the pads, further procf of this ia the fact that whila Mew Zork used mrnmmmmmfmmmmmmm mmmm LIA15599 fncdt tluw -5- load Farau* Tlbrstlow A Auanary and Outlook to b* alnoat 100 par east of the building pod Mriat, wa new fat iaqslrtM ad order* fra* Florida, Chicago, Canada, tarn, Delaware, Kano**, and (Mar rooa ocnplwtaly unlik* Haw lork In buildlx* drooity, severity of vibration oureaa, typ# of aoll, and ao forth. low In today'* picture, tbara ha* baan a curious tiendi tddl* wa haaa a food aitart toarf getting the najorfty of building eeoatroetion Job#, adra vibration 1* a prchlan, nacblnery aowitlnfa have boocne o aoll part of tho vibration pad narfcat.
