RE: 1991 Update of Cost/Benefit Study
As you may be aware, we commissioned Dr. Joseph Zicherman of IFT Technical Services to do an update of the Cost/Benefit Study on InPlace Costs and Technical and Regulatory Constraints to Use of PVC Based Pipe, Tube and Conduit in Construction. The original report was based on data gathered in 1988 and published in September 1989.
We had asked for an updating so that the paper that Dr. Zicherman presented at the Construction Specifiers Institute Meeting in San Diego on June 29 would be based on current information.
Enclosed is a copy of the report just received from IFT giving the results of the update. Essentially, the data confirms the findings in the earlier report about the economic advantages that accrue from the use of PVC although all of the cost numbers have changed due to changes in material prices and labor rates. This is for your information and files.
Separately I have asked Nora Jacobs and Dan Stanowick at Edward Howard & Company to advise me of the costs involved in preparing an update of the 4-page summaries that were issued in July 1990 that were based on the original cost/benefit study.

4.0 CODE APPROVALS
4.1 Building Codes
In terms of building code acceptance and approval, all three model building codes permit unlimited use of combustible (i.e., PVC) piping, tube, and conduit products in all construction types. Each code contains somewhat different caveats with regard to the use of these products, but all depend on the ASTM E-814 fire-test method to demonstrate adequate thru-penetration fire performance. ASTM E-119 may be invoked as well to express overall construction assembly performance when PVC pipe, tube and/or conduit are included. Recent favorable review of a revised edition of the PPFA installation manual by CABO-NES will enhance acceptance of NC piping products by the building code community.
Relative to building codes, no bars exist to unlimited use of PVC pipe, tube, or conduit, provided the appropriate subsidiary code (electrical or plumbing) allows for their use. Such Building Code acceptance, however, is often based on demonstrations of satisfactory performance in E-814 or E-119 testing mandated by the alternate materials and/or installation methods language found in each code.
Restrictions to the use of combustibles in concealed spaces and/or return air plenums do affect use of PVC products. These are appropriate if the space is used for an HVAC function, but have no technical merit in other cases.
4.2 Plumbing Codes
While the Standard (SBCCI) and National Building Code (BOCA) both utilize plumbing codes which do not restrict use of PVC pipe, this is not the case with the Uniform Plumbing Code which is promulgated by IAPMO (The International Conference of Plumbing and Mechanical Officials) for ICBO (International Conference of Building Officials).
Thus, in geographic areas where the IAPMO code is the adopted plumbing code, use of plastic pipe is restricted to buildings which are three stories or less in height. Because of this specific restriction, "alternative materials and methods interpretations" found in the building code are typically unavailable to the end-user/specifier since the building official would be required to overrule both his plumbing inspector and the adopted plumbing code. Thus, existence of specific acceptance criteria which will allow use of PVC materials in the Uniform Building Code is rendered moot at this time where

A total of eight combustible assemblies (i.e., those including wood framing members) were analyzed. Non-combustible, fire-rated assemblies requiring fire-resistive detailing analyzed included twenty-one different configurations with metal stud-based framing. Four monolithic walls and floor/ceilings based on concrete slabs or block were also analyzed.
Many of the metal-framed walls (as well as wood-framed ones) differed only in the presence or absence of fiberglass batt insulation (usually for sound control) or in thickness of walls. For example, walls containing plumbing chases varied in thickness as related to sizing of DWV found in a particular chase. Conversely, while walls with electrical service only were of minimum thickness, ah walls were considered to contain the minimum number of outlets required by the applicable code for the number of outlets in each room.
Additionally, several of the wall configurations were non-conventional, e.g.,
gypsum wallboard on one side of metal studs and tile or marble over mesh/grout on the other.
plumbing chases bounded by a concrete slab (shaft) wall on one side and gypsum wallboard on the other.

5.0 TECHNICAL CONSTRAINTS
The types of fire-rated construction assemblies occurring in the buildings analyzed in this study are quite broad. Thus, they present a good vehicle for reviewing available technical data as it relates to construction assemblies in general being used with PVC products.
They range from relatively standard assemblies being penetrated by PVC piping from 3/4" in diameter (condensate drains) through 1-1/2" or 2" DWV lines and sprinkler lines. Such walls also include piping as large as 4", with greater diameters typically passing through slabs. They all contain ENT and most have openings for electrical boxes. Overall, the expanded efforts by manufacturers of thru penetration firestopping materials and devices have been fruitful as expressed in the hundreds of such systems found in UL handbooks, as well as in CABO-NER Research Committee recommendations.3
5.1 Plumbing Walls
Of the wall types, the most common, in terms of available supporting test data, were stud walls based on 2" x 6" (nominal) wood and metal studs for plumbing uses. Both have been fire endurance tested with and without fiberglass insulation. Because these walls were tested with both thru-penetrations and simulated drain lines and vent stacks, such walls containing either PVC thru-penetrations and/or drain lines and/or vents should be acceptable to code authorities.
In terms of fire endurance, duration of tested walls (hourly-rating), 6" deep one and twohour walls with metal framing have been tested directly, as have one-hour wood-frame walls. Given that metal frame test results are commonly accepted for use in wood framing systems of identical dimensions and fire endurance ratings, two-hour wood walls containing PVC, DWV, and DHCW piping should be acceptable. While no testing of PVC plumbing thru-penetrations with generic firestopping has been conducted for shaft walls, proprietary systems for such installations have been tested and are UL listed.
3Examples of these efforts have resulted in recent CABO-NER [NER 370 issued 4-91] recognition for
Model Building Code reference of the PPFA insulation manual 'Plastic Pipe in Fire Resistive Construcdon" and publication of The Vinyl Institute sponsored research describing PVC-DWV Gie performance in NFPA, BOCA and ICBO journals.

the Uniform Plumbing Code is used for buildings over three stories. However, from 1991 forward PVC pipe can be used in all types of construction (combustible and non combustible) three stories or less.
The situation in the case of the IAPMO code creates a potentially serious impact to the expanded use of PVC-DWV and DHCW in the Western and mid-Western U.S.. Continuation of the present policies will limit growth of PVC product use in these areas.
4.3 Electrical Codes
The National Electrical Code, promulgated by the National Fire Protection Association (NFPA), allows for unlimited use of PVC-based conduit and tubing as long as it is not directly exposed to room areas. Specifically, these products must be protected (at minimum) by a 15-minute thermal barrier. In addition, they cannot be installed in areas where they will be exposed to return air flows for heating, ventilating, and air conditioning systems as in plenum spaces.
Few code-related bars to the use of PVC-based electrical products appear to exist at this time. However, further testing for both thermal barrier and fire endurance properties of assemblies incorporating these products is still needed. This will be discussed in the next section.
4.4 Major Cities
While few small to medium sized cities write their own building codes, several large cities do write codes impacting use of PVC (and other) plastic pipe, tube, and conduit products. Examples include Chicago, Seattle, San Francisco and Denver. In many of these situations, partial approvals and restrictions for these products exist through amendments made to a specific, adopted model code. Recent legal action in Pittsburgh has lifted many of these restrictions.
Extensive lobbying efforts, as well as presentation of appropriate technical data, will be needed before cities such as those listed above can be expected to allow expanded use of PVC products. In addition, because of the role unions, cost-plus contractors and contracting associations play in code adoption processes and enforcement in such cities, acceptance of the PVC products will require continued long term planning and work.

6.0 ECONOMIC/COST BENEFIT SUMMARY
Table and charts which follow summarize analyses conducted for the four classes of buildings studied. Numerical values are based on an average of dollar costs in the cities surveyed. Thus, they reflect the mid-range in cost of each product as installed.
Results show that use of PVC-based piping and electrical products present clear advantages overall in spite of the fact that they require additional fire-resistive installation detailing for certain applications.
Findings are sensitive to some extent to pipe diameter, but most of all to number of penetrations occurring in subject structures. For example, the data for the highrise residential and commercial structures both include substantially higher material and/or labor costs for particular pipe sizes such as 2" and 3" PVC-DWV or 1/2" CPVC-DHCW. The reason for this is n&t the cost of the pipe itself. Rather these are the sizes of pipe requiring firestop detailing which leads to substantially higher unit (i.e., price per foot installed! costs. When included in the overall price estimates however, the impact of such high unit costs are reduced. Such data support the need for an easily used thrupenetration firestop system (i.e., one with a low cost of installation).

5.2 Electrical In Walls
The situation with ENT and PVC-RNMC is similar to that with PVC-DWV, although few test results can be found justifying use of these products in other than two-hour walls and partitions.
Likewise, tests of the two-hour electrical assemblies were carried out with assemblies of 4" nominal depth. In the absence of data for thinner two-hour assemblies, a knowledgeable code official would be justified in refusing use of PVC electrical products in other than two-hour walls of nominal 4" or greater thickness. This lack of one-hour test results has already proved problematic in the field for ENT use in thinner walls containing ENT only or PVC boxes and ENT.
5.3 Floor/Ceiling Assemblies
With regard to floor/ceiling assemblies, no PVC plumbing products have been successfully tested in full-sized wood stud or metal-framed assemblies for the full duration intended in the tests.
NEMA's PVC conduit section has now conducted a successful fact-finding series with a non-combustible F/C assembly at Underwriter's Laboratories. This has led to a new three (3) hour CABO-NER recommendation. Earlier, testing with wood-framed F/C systems was conducted to assess the impact of the use of PVC boxes in particular on such assemblies.
Based on test results available, (with the exception of the National Electrical Code regulation requiring 15-minute finish rating protection with PVC-ENT use and building code prohibitions on their use in return-air plenums), use of PVC-ENT and conduit electrical products can be better justified in F/C assemblies than can use of PVC-DWV pipe.
SS077-02.rja
CTL027055
7.0 CONCLUSION
Cost savings attainable through use of the PVC products studied are significant. This is the case even with the necessity to utilize firestop detailing which increases costs substantially, as is well demonstrated by data for pipe sizes commonly exiting from within fire-resistive assemblies such as shaft or other walls backing up on kitchens, lavatories, etc.
To realize the cost advantages the PVC products evaluated in this report and to achieve greater market penetration for such products, concerted focus on the code process in the Western U.S. will be needed along with continued work in major cities. In addition, the possible requirement of additional supportive fire-test data in selected plumbing and electrical product areas by local code officials will have to be addressed.

4 The total cost per lineal foot of pipe installed is affected by the number of penetrations per total pipe footage, e.g. for 200 penetrations/4000 lineal feet, the lineal foot cost is hardly affected. Whereas with 200 penetrations/800 lineal feet, the cost per lineal foot is greatly affected.

MATERIALS NOTES
* In order to prepare the needed data, plans for each building were analyzed to determine (a) number of feet of product used (i.e., pipe, tube, or conduit), (b) number of fittings needed and (c) detailing needed to utilize the PVC products (Le., firestop detailing, hangers, etc.). These materials were then totaled for a given size of pipe, tube, or conduit. Next, the unit cost was determined by dividing the total cost (of all materials) by the total number of feet used. This result is the "material cost" which is the average-per-foot cost. Next, labor costs associated with installing the number of feet of pipe, fittings, firestop and other detailing were totaled by pipe size. An average, again based on total feet of pipe of a particular size, was then taken representing an average labor cost. The sum of these two averages was used to determine the unit cost figure quoted. San Francisco was used as a base city, although calls were made to sources in the other five cities to develop local material, labor, and unit costs. This methodology is standard to the construction estimating industry for large projects.

ELECTRICAL NOTES
In completing the calculations required for the electrical portion of the study, two basic criteria were used. The lighting circuits conduit/wire and the device circuits conduit/wire were compared when using both electrical metallic tubing (EMT) and electrical non-metallic tubing (ENT). Both conduit and wire systems were figured with appropriate numbers of couplings and terminators and with #12 copper wire required for the circuits. In addition, both were shown at 3/4" and 1" sizes for each type of conduit. Material costs were determined by phoning the Graybar distributors in the cities used for the study. The costs were discounted and marked up to reflect the retail value of the materials used. Labor rates were also calculated by using each individual city union labor rate and applying it to pre-determined unit man-hours.

EXECUTIVE SUMMARY
It has long been assumed that PVC-based (polyvinyl chloride) plumbing pipe, tube, and conduit products offer cost savings in construction as compared to their metal counterparts. In this study, this assumption has been tested by developing comparative cost data for these two competing classes of products.
Specifically, the following competitive cost estimates were prepared:
Cast iron versus PVC drain, waste and vent (DWV) pipe
Copper tubing versus CPVC for domestic hot and cold water (DHCW)
Electrical metallic tubing (EMT) versus electrical non-metallic tubing (ENT) products used as raceways for lighting and local electrical circuits
Four different building types ranging from highrise, non-combustible construction through lowrise, fire-rated wood frame were used for costs analyses. The specific buildings upon which the estimates are based have actually been constructed; they are not hypothetical. Estimates were prepared by a nationally recognized cost estimating firm and are organized according to CSI (Construction Specifications Institute) format. Results are based on current survey data of supplier and installer costs and rates in six cities across the USA to determine geographical influences on comparative costs of the competing materials.
A survey was also conducted to determine technical and regulatory constraints regarding usage of PVC-based products. This survey addressed technical justification for product use based on adequate fire performance data. Finally, building codes were examined to determine if product was use acceptable based on model code provisions.
In terms of regulatory bars, few exist to unlimited use of most of the PVC products included in this study.1 In terms of technical bars, there has been extensive fire testing of the PVC products considered here. However, additional fire test data for one-hour applications of ENT products in walls would be of value in assuring increasing product acceptance. Likewise, although theoretical justifications can be developed obviating their need, additional fire test data for PVC piping installed in fire rated floor/ceiling assemblies and walls less than 6" thick could be required by local code officials before sanctioning use in their jurisdictions.
Finally, results showed the PVC-based products to be between 20 and 30 + % less as installed, even when costs of firestop detailing to insure maintenance of fire resistive integrity with their use are included.
^he West Coast IAPMO-based Uniform Plumbing Code is a glaring exception to this.

1.0 INTRODUCTION
PVC-based (polyvinyl chloride) construction products are becoming increasingly available as replacements for conventional products. Typically, they provide both direct advantages in performance and cost/benefit advantages to the construction industry.
With this in mind, preparation of an in-depth assessment of the cost effectiveness of PVC based products versus their conventional, metal counterparts for pipe, tube, and conduit were the subject of this study.
Specific study objectives were:
to compare direct, in-place costs of these products with competing metal products,
to consider technical ramifications related to fire safety associated with such replacement,
to evaluate current fire-related, regulatory (i.e., model code) barriers to use of these products.
Specific data developed include:
Direct Cost Comparisons For In-place:
PVC drain, waste, and vent (DWV) piping versus cast iron soil pipe.
CPVC (chlorinated PVC) as a replacement for copper hot and cold water (DHCW) supply piping.2
PVC-ENT (electrical non-metallic tubing) as a replacement for EMT (electrical metallic tubing).
Assessment of existing model building regulations affecting use of PVC products.
Discussion of technical barriers to use of the PVC products.
Technical barriers were identified by evaluations of testing and research records and literature related to fire performance of the products under study.
2Attempts were also made to develop data on CPVC based Ore sprinkler systems. Due to the lack of Held data on the use of these products, as well as the nature of the cost estimating process, the estimating approaches available did not appear of sufficient reliability to be included after an in-depth analysis was conducted.

2.0 METHODOLOGY
Study results were obtained by utilizing actual plans, specifications, and materials take offs for buildings of differing construction types, all of which have actually been completed. Results are not based on hypothetical structures.
For a specific description of the cost estimating process used, see Appendix A.
2.1 Materials and Installation Estimating
Types of materials required for construction of the original buildings were modified to take into account installation-detailing unique to use of PVC products. In order to do this, IFT personnel identified installation detailing for PVC products which differed from conventional products. The estimators then modified conventional detailing as needed for safe use of the PVC products. Thus, additional detailing costs have been factored into estimates for each PVC product cost estimate.
PVC based products were estimated with specific firestop-detailing for both DWV and DHCW as is consistent with their safe use in the field. The cast iron DWV and copper DHCW on the other hand were estimated with no application of firestopping beyond grout which may be routinely applied with wallboard installation. While this may seem a conservative estimating method for the study, it reflects current estimating practice. More importantly, it expresses true economic comparisons for current construction practices used.
Material take-offs were prepared in Spring, 1991 and reflect pricing of materials and labor at that time. The analysis took into account geographic variability in both raw materials and installation pricing for a total of six cities. Bases for pricing of products were obtained from sources in the field and are listed in Construction Specifications Institute (CSI) format. Analyses were conducted by a major nationwide cost estimating firm for IFT TECHNICAL SERVICES.
2.2 Item Pricing
Specific items of interest related to pipe pricing, firestopping costs, and basis for foam core PVC pricing can be found in Appendix A.
Appendix B includes comments on electrical product pricing bases used.
83077-02.rja
CTL027099
Appendix C includes pricing bases for use of 3M FIRE BARRIER cost estimates. This product was determined to be the more cost effective when compared to other products considered. USG THERMAFIBER was the "generic" thermal insulation used for price quotes. Common fiberglass types could be used in certain applications. This would result in further net savings for specific jobs.
23 PVC Cost/Benefit Ratios
In addition to cost estimates for each project expressed in dollars-per-unit for the products studied (i.e., cost/foot including labor, detailing, accessories, etc.) ratios have been developed which express direct comparisons between competing classes of products as installed.
These ratios are reflective of relative costs of installed metal versus PVC systems regardless of whether union or non-union installation is considered, since the ratio of productivity between these installer classes should remain constant. They also reflect the substantial differences in construction costs in different areas of the U.S.
2.4 Code Analysis
An analysis has been prepared as part of the study (Section 3) of applicable model codes provisions which regulate use of PVC products. The examples developed do not represent every possible installation situation, but do cover a broad group of installation possibilities. The analysis includes references to prescriptive code provisions which bar use of particular products where technical feasibility for their use exists. Thus, code changes will have to be effected before such technically feasible uses of PVC products are permitted in jurisdictions covered by the codes in question. Examples include removal of the three story restriction found in the 1991 Uniform Plumbing Code and development of acceptable code language to permit use of PVC-based pipe in appropriate plenum spaces. The latter is especially true for plenums in buildings constructed with combustible materials.
2.5 Technical Analysis
Bars to PVC product use from a technical standpoint are identified in Section 4. Such bars exist because particular types of construction assemblies identified have not been demonstrated to show necessary fire endurance.

3.0 COST ESTIMATE ANALYSIS RESULTS
3.1 Non-Combustible, Highrise Residential Case
In this case a Type-1 non-combustible highrise project has been analyzed. The building analyzed was a 30+ story, high quality (non-"spec" and non-fast-track) residential project. Plastic products for which analyses were conducted include: replacement of cast-iron DWV piping with PVC-DWV, DHCW supply piping replacement with CPVC supply piping, EMT for electrical power distribution and signaling replacement by PVC electrical
non-metallic tubing (ENT) where appropriate. The tables which follow summarize comparative in-place costs for plumbing pipe (DWV and DHCW) and electrical systems estimated. Because this is a residential project, substantially more pipe is used than in the commercial highrise (Case 3.2). Consequently, more plumbing thru-penetrations occur as well, which impacts unit cost (cost per foot). The tables also include ratios of the two competing products classes showing the fractional in-place cost for PVC replacement of metallic materials. Appendix D.l contains the raw data from which the following tables were derived. The reader may want to evaluate the appendices to discern trends in in-place costs versus pipe size, etc.

.2 Highrise (Non-Combustible) Business/Commercial Case
This case study is for a highrise, non-combustible sprinklered building, including upperstory office occupancies and lower-story commercial spaces. Because of the typical highrise core design used, distribution of utilities is, in general, restricted to the central building area. Replacement estimates have been prepared for PVC-DWV (replacing cast-iron) and CPVC hot and cold water supply piping (replacing copper). Electrical conduit (EMT) is replaced by ENT and RNMC (rigid non-metallic conduit) as appropriate. The tables and Appendix D.2 are arranged as per the preceding Section 3.1 .

3.3 Wood-Frame Townhouse Case
This project is a residential townhouse development which also includes common areas and limited commercial spaces. Estimates were for typical residential units only.
Specific replacement estimates were prepared for PVC in place of cast iron DWV piping and CPVC for copper DHCW.
In this case, PVC-ENT was directly compared to EMT, although in many jurisdictions for a project of this type Romex non-metallic sheathed cable would be the economic material of choice. In the jurisdiction where the project was actually built, however, electrical wiring needed to be installed within a raceway. Thus, EMT was originally used.
Summary results of the analyses follow and raw data can be found in Appendix D.3.

3.4 Strip Shopping Center Case
Of the four projects analyzed, this case represents the lowest ratio of penetrations of fire-rated assemblies requiring firestop detailing to quantity of pipe, tube, or conduit. This is because the buildings are single-story and typically are separated by occupancy separation walls which are unpenetrated for utility distribution. Services enter each unit separately.
In addition, the areas of the individual units are sufficiently small that they are undivided internally by fire resistive partitions.
Summary results of the analyses follow. Raw data can be found in Appendix D.4.
