APPLICATION OFTHE CAPITOLINE TRANS-A-PLATE TRANSPARENCIES

The pressur. nsitiv. transparencies may be very easily and quickly applied to your

project tracings. Drawings with properly affixed transparencies may be printed repeatedly and

handled as frequently as any functional type drawing with no adverse effect. The following

procedure should be used in the application of the transparency to the project drawings:

...-......s.j~ .appropriate siandard detail transparency for project on which you are working.

The te po a' today'. econo y, the population e.plo.ion, higher standards o'living and the lechno/ogicol advancesin the construction trades all contrihute to increasing demands on the engineer to produce more and mor. in COn-stantly di inishing periods a' ti e. With Ihis situation beco ing increo.ingly apparent Ihrough his oWn personale.periences as a consulting engineer, Lee Kendrick co e 10 Ihe conclusion Ihot "Ihere ust be a be"e, way 10run a railroad," as the saying goes.

Extensive re arch inlo engineering proble s, available equip enl to do various lobs, specifications, codes,presenl-doy drolling proclice., new reproduclion oteriols and advanced ,eproduction ethods, plus any hours 01consultolions with lellow engineers and relaled trodes en, resulted in Ihis lirsl edition 01 Ihe Healing, Venlilatingand Air Conditioning Manual. In conjuncfion with this unique co pilotion a' engineering data perlin en I 10 Ihe lield., a new concepl in the use 01 Slandard Design Details has ode possible the rep,oduction 01 standard designsprinled on fronslucent pressure'sensitive drafting material which can be applied directly to a frocing, thus eli inot.ing countless hours 01 repetitious drafting time.

The express purpo 01 this manual and use 01 the standard detail system, is to save many valuable mon"",ours Inthe p,eporotion 01 working drawings as well as clearly present the requi,ed co ponents 01 a mechanica' system inco lderobly more deloil than would no,molly be practical by lormermethods. The author has been using the co ponents lor years in his practice with proven savings 01 valuable time and a mo,e complete and accurale interchange 01 inlo,mation between the builde" the design team and the inslolling contractor.

You will note that Ihe standa,d delail plates in Ihis manual depict lor g,eoter and mo,e inute details than limewould pe,mit under lorme, melhods, yet Ihey are so d,awn to a size Ihot is well within the limits 01 cleo' legibilitylor easy reading no motte, what method 01 ,ep,oduction 10, dislribulion copies is ulilized.

By u.ing this system 01 stando,d details, you will ,eadily discove, that it p,ovides a ,eody and c:.onstont ,ele,enceand design ethod 'A' the selecfion 01 equipmenl to meet spedlic ,equi,ements. Components ,emoin basicallycan slant 1,0 p,oject 10 projecI, bUI the stonda,d details contained he,ein can be very easily alte,ed when necessary to meet a specific situation.

Adequate detailing 01 components 'A' Heating, Ventilating and Ai, Conditioning systems is a very necessary steptowo,d obtaining the best end ,esult in the con.t,uction 01 the system, but 10' too olten these detail. a,elelt until

the end 01 the design stages, thereby ,esulting in ski py, if any, details 01 the co ponents. F,equently, co ponents are not deloiled at all, but left to thl writt.n word 01 thl specilic olions. It has be.n lound, when thesecomponents are present.d in gr.oler d.toil, syste p,ices are lrequently lower and coordinolion b.tween Architect.Engineer and Conl,octo, goes much smoother since both parties know exactly what is exp.ct.d. Lack a' odequotlin'o,motion ,esults in isund.rstonding a' exactly what is required and often requi,es considerable ti e in verbale.planotions 0' clo,ilicatlon d,owings. It is the goal 01 this book nol only to iprovi the qu~lity 01 the H.oting,Venliloting and Ai, Conditioning dltoils but to considerably reduce Ihe nuber 01 manhours required 10 p,oducithese d,awings. The tedious task 01 Iracing d.loils and the 'requlnl mislokes in I,onsc,ibing can now b. eliminatedby use 01 Ih. I,onspo,.ndes described herlin.

The delails that show as ploles in Ihls book are all deloils 01 stondo,d components a' H.oting, V.ntilotion and Ai,Conditioning system s. The components are u d repeot.dly Ira job to job th,oughout the country\ and vary onlyslightly in the arrongelllenl. This sysll" does not cantemplot. the standard deloiling 01 syst s; .inc. this shouldbe lelt 10 the judgmenl 01 Ihe designer. The details hove b.en coo,dinaled with the anulacture 01 equip enlshown and all in'o, alion needed 'A' the tting and installation 01 this equlp enl. In addition, where there is aschedule 01 capacilies required, il has been shown at the lower pa,I 01 Ihe delail. This was done so thaI if arethan one 01 the co pon.nls is on a p,oject, thelines may be I.nd.d and are co ponents shown in the schedule.The schedules have been checked 10 see thaI all in'or atian required by the confroclor and the onulactvrer isincluded therein. In this way, it is lell that Ihe olten lorgo".n dolO will not inadvertantly be overlooked.

The concept a' Ihis syste was based on the premi that, "once a detail has be drawn, it is onlY aula'your pockel every Ii e you pay a mOanto redraw it or trace it lor each continuing application." This cast ligurebeco es Iven greater when you relate it 10 the loss 01 a man's li e that could have been are prolitably spenldoing crealive syste design.

USE OF THE TRAHSPARENGY DURINGPRELIMINARY DESIGN STAGES:

USE Of THE TRAIlSPARENCY DURINGTHE WORKING DRAWING STAGES:

USE AS A METHOD FORSTANDARDIZING DESIGN:

OTHER USES, ' If ANY CHANGE OR DELETION IS, IH THE JUDGMENT Of THE DESIGNER, NECESSARY, IT IS QUITE EASY TO REMOVE ANY LINE OR LETTER FROM THE

TRAIlSPAREHCY BY THE USE OF AM ELECTRIC ERASING MACHINE. ADDITIONS MAY BE EQUALLY AS EASILY MADEWITH THE USE OF A DRAFTINGPENCIL WiTH "H" LEAD. THE TRANSPARENCY, YOU WILL FIHD, TAKES PENCIL AS WELL AS THE PROJECT TRACING PAPER.

IT HAS BEEN FOUND THAT THE TRANSPARENCIES MAY BE USED DURING PRELIMINARY DESIGH STAGES IN THE FOLLOWING MANNER: WHEN THEARCHITECT OR EHGINEER REQUIRES DESIGN INFORMATION REGARDIHG THE WEIGHT CHARACTERISTICS, PHYSICAL SIZE, ETC. OF MECHANICALCOMPONENTS, IT IS QUITE EASY TO MAKE A PRINT OF THE TRANSPARENCY, MARK THESE CHARACTERISTICS OH THE PRINT AND SEND IT TO THEARCHITECT OR SrRUCTURAL ENGINEER FOR HIS INFORMATION. INFORMATION USUALLY REQUIRED BY THE ELECTRICAL ENGINEER, SUCH ASHORSEPOWER AND VOLTAGE AND CURRENT CHARACTERISTICS, MAY ALSO BE MARKED ON A PRINT' AND SENT TO THE ELECTRICAL ENGINEERFOR HIS USE DURING THE DESIGN STAGES OF TtIE PROJECT.

THE PROJECT DESIGNER WILL FIND THE DETAILS IN THIS BOOK A WELCOME PICTORIAL AID IN EXPLAINIHG TO A DRAFTSMAN OR CLIENT EXACTLYWHAT PIECE OF EQUIPMENT HE HAS IN MIND AND PRECISELY HOW HE IHTENDS TO INSTALL IT. OFTEN A PICTURE OF THE COMPONENT WILLQUICKLY CLEAR uP AilY LACK OF UNDERSTAIlDING WITHIN THE DESIGN TEAM AS TO THE EXACT INTENT, THEREBY SAVING VALUABLE DESIGNTIME AIlD ALLOWING DEADLINES TO BE MET. THE DESIGNER CAN, FURTHER, BETTER PREPLAN THE WORKING DRAWINGS AND PINPOINT EXACTLY WHAT DETAILS ARE TO BE USED AND ON WHAT SHEETS THEY ARE GOING TO BE PLACED.

OH SMALLER PROJECTS WHERE IT ISNOT DESIRED TO PRESENT DRAWINGS IN GREAT DETAIL, THE USE OF THE REFERENCE SYSTEM IS SUGGESTED.IN THE REFERENCE SYSTEM, THE DESIGNER CAN SHOW IN OUTLINE ON THE SMALL SCALE PLANS THE ITEM OF MECHANICAL EQUIPMENT WITH ANOTE THAT STATES, FOR EXAMPLE - "THE PU~IP SHALL BE INSTALLED IN ACCORDANCE WITH THE HEATING, VENTILATION AIlD AIR CONDITIONING MANUAL, PLATE NO. 62". THE USE OF THE REFERENCE SYSTEM IS NOT RECOMMEl:lDED ON LARGE PROJECTS, SINCE IT IS FELT THAT IT ISFAR BETTER TO HAVE THE DETAILS OM DRAWINGS WITH THE REST OF THE PROJECT PLANS SO THAT ALL DETAILS WILL BE IN ONE DOCUMENT.

WITH THE GROWTH OF THE CONSTRUCTION INDUSTRY AS A WHOLE, AND THE ARCHITECTENGINEER DESIGN PROFESSION SPECIFICALLY, HAS COMEA SHORTAGE;OF QUALIFIED DESIGNERS. THE RESULT HAS BEEN A NECESSITY TO TRAIN NEW DESIGNERS AS QUICKLY AS POSSIBLE. THE BOOK ANDTHE TRANSPARENCIES OFFER AN EXCELLENT TRAINING INSTRUMENT FOR YOUNG NEW DESIGNERS NOT THOROUGHLY ACQUAINTED WITH THE VARIOUS COMPONENTS. THE DESIGN NOTES ACCOMPANYING THE DETAILS OFFER A CHECK LIST FOR INFORMATION REQUIRED ON THE SCHEDULES ANDDRAWINGS AND A CONCISE METHOD Of DESIGN. SCHOOLS AND VOCATIONAL CLASSES WILL FIND THE BOOK AND DETAILS AN EXCELLENT REFERENCE TEXT IN ATTEMPTING TO TEACH THE DESIGN MAKEUP, AND USE Of THE VARIOUS PARTS THAT GO TO MAKE UP A COMPLETE SYSTEM.

LARGER FIRMS WITH A LARGE STAFF OF DESIGNERS WILL FIND THE BOOK AND THE TRANSPARENCIES AN EXCELLENT MEANS OF STANDARDIZATION.PRINCIPALs IN THE FIRM CAN, BY GIVIlG EACH DESIGNER A BOOK AND INSTRUCTIONS TO FOLLOW THE DETAILS, ACHIEVE A FORM OF STANDARDIZATION IN THE DRAwiNGS THE FIRM ISSUES. GOVERNMENT, INDUSTRY, SCHOOL BOARDS, INSTITUTIONS, ETC. ABOUT TO EMBARK ON A LARGE-SCALECONSTRUCTIOH PROGRAM IH WHICH NUMEROUS ARCHITECTENGIHEER FIRMS ARE TO BE USED, CAN, BY ISSUIHG THESE DETAILS, ACHIEVE AGOOD MEASURE OF STAHDARDIZATIOHTHROOGHOUT THE COURSE OF THE COMSTRUCTIOH PROGRAM.

WHERE ADEQUATE DETAILS Of THE COMPONENTS HAVE HOT BEEH GIVEH TO THE IHSTALLIHG CONTRACTOR, THE CONTRACTOR WILL FIND THESEDETAILS WILL EHABLE HIM TO PROVIDE HIS JOB SUPERINTEHDENT' A DETAILED DRAWIHG OF THE METHOD Of INSTAllATION Of EQUIPMENT, WITHOUT THE NECESSITY Of SPENDIHG HOURS SKETCHIHG OUT THE IHSTAlLATIOH DETAILS. THE CONTRACTOR WilL ALSO FIND THAT THE DETAILSARE QUITE US '. WHEN MAK'IHG A DETAILED COST ESTIMATE OF A PRO! THAT DOES HOT HAVE ADEQUATE DETAILS, THEREBY PROVIPIHGHtM WITH A VIS", .." CHECK Of TilE MANY IT,EMS REQUIRED FOR COMPLETE ,TAlLATIOH.
