WAYNE, N.J., August 8, 1990 -- Plumbing contractors can save up to 44 cents on every dollar by switching to PVC (polyvinyl chloride, or vinyl) pipe when they install plumbing systems, a study performed by a leading independent research firm shows. The same study found that PVC used in drain-waste-vent (DWV) applications can cost up to 37 cents less per dollar than competitive materials.
The study, the first of its kind to include installation and labor costs in estimating the savings advantages of PVC pipe, was conducted by IFT Technical Services, Berkeley, California.
Estimates were based on actual building costs in Atlanta, Boston, Cleveland, Houston, San Francisco and Seattle. Plumbing and DWV systems for four types of structures were evaluated: a wood frame townhouse, strip shopping center, high-rise residential building and a high-rise office building.
*
On average, the study found that CPVC (chlorinated PVC) pipe systems cost between 23 to 44 percent less than copper in new hot and cold water installations, according to Joseph B. Zicherman, Ph.D. , president, IFT Technical Services.

When PVC DWV was compared to cast iron soil pipe in drain, waste and vent pipe installations, the savings varied from 16 to 37 percent, he said.
"That can mean a savings of between 23 and 44 cents on every dollar spent to install hot and cold water systems and 16 to 37 cents for a typical DWV system," Zicherman said.
"This study confirms that there are significant cost advantages to using PVC pipe," said Roy Gottesman, executive director of the Vinyl Institute, which funded the IFT study.
PVC piping has proven to be safe, dependable and capable of meeting existing building codes, he said. Now there is concrete evidence of its superior economic performance.
"Moreover, this study doesn't even examine the total lifetime costs of the various systems and the related replacement costs. When you consider that PVC can easily outlast competitive materials, the advantages of PVC become even more obvious," Gottesman said.
PVC pipe has found broad use in plumbing applications. Because of its cost advantages and long life, pipe commands approximately three-fourths of the plastic pipe market. It is expected to maintain a strong hold on the market well into the year 2000.
The Vinyl Institute is a national trade association representing the leading manufacturers of vinyl, vinyl feedstocks, additives, and film and sheet products. Headquartered in Wayne, New Jersey, it is a division of the Society of Plastics Industry, Inc.

This summary presents key findings from a study conducted for the Vinyl Institute by IFT Techni cal Senices. Berkeley, California in September 1989. The study, entitled "A Cost/Benefit Study: In-Place Costs and Technical and Regulatory Constraints to Use of PVC-Based Pipe. Tube and Conduit in Construction," reviewed the use of PVC DWV (drain-waste-vent) pipe, plumbing pipe and electrical nonmetallic tubing (conduit). The findings relevant to the use of PVC DWV pipe are discussed here.
For individuals seeking cost-effective ways to meet performance requirements in DW\ ' systems, the study provides important economic data: when the cost to install comparable cast iron and PVC DWV systems in six major U.S. cities was calculated, the PVC systems cost up to 37 percent less than the competitive metallic system. Direct comparison data of this type -- including installation and labor costs -- have not previously been available. Details of the study follow.
PROJECT OVERVIEW
PVC (polyvinyl chloride, or vinyl) construction products are increasingly used as replacements for "traditional'' products. Typically, they provide both direct advantages in performance and cosi/benefit advantages to the construction industry.
Although specific information on installed costs has not been available, it long has been believed that the full, installed cost of PVC DWV is substantially less than that of competitive metallic products. This study was designed to compare the fully installed costs of these two competing classes of products, thereby helping system specifiers make more complete comparisons between the merits of the two systems.
PROJECT DESIGN
Specifically, estimates were prepared to compare the costs of installing cast iron soil pipe and PVC drainwaste-vent piping in four different types of installations:
A noncombustible high-rise residential building A noncombustible business/commercial building
A wood frame townhouse A strip shopping center
The specific buildings upon which the estimates were based are actual buildings that were constructed using cast iron soil pipe. Estimates for comparable PVC DWV systems were developed by a nationally recognized cost-estimating firm (Lee Saylor and Associates of Concord. California) according to Construc tion Specification Institute (CSI) formats.
In order to make sure that the estimates for the two systems reflected actual safe installation practices, firestopping detailing was included in the estimate prepared for each PVC DWV system, while the cast iron system was estimated with no application of firestopping since grout applied along with the installation of wallboard typically is the only type of firestopping used with cast iron. The additional costs for the firestopping were factored into the estimates for each PVC system.
In order to provide costs on the various types of PyC DWV systems that are available, four different installation scenarios were estimated:
Replacement of cast iron soil pipe with PVC solid core DWV piping, using a proprietary firestop. Replacement of cast iron soil pipe with PVC solid core piping, using a generic firestop. Replacement of cast iron soil pipe with PVC cellular core piping, using a proprietary firestop. Replacement of cast iron soil pipewith PVC cellular core piping, using a generic firestop.
In order to provide comparisons representative of labor and material costs throughout the United Slates, supplier and installer costs in six major U.S. cities were examined:
San Francisco Boston
Cleveland Houston
`Seattle `Atlanta
KEY FINDINGS
On average, the PVC DWV system cost between 16 and 37 percent less to install than the compa rable cast iron system -- even when the extra detailing required for firestopping the PVC system was included. (See cost summary table, next page.) Tables identifying the costs on a city-by-city basis, for each type of installation, follow.

DATA PREPARATION
In order to prepare the needed data, plans for each building were analyzed to determine the number of feet of pipe used, the number of fittings need and detailing such as firestop needed to use PVC. Those materials were then totaled for the given size pipe.
Next, the unit cost was determined by dividing the total cost of all materials by the total number of feet used. The Fesult was the ''material cost." which was the average per-foot cost.
Finally, labor costs associated with installing the number of feet of pipe, the fittings, firestopping and other detailing were totaled by pipe size. An average, again based on total feet ol pipe of a particular size, was then computed to obtain an average labor cost. The sum of those two averages was used to determine the installed cost.
MATERIAL SPECIFICS
Pricing data included costs for pipe, fittings and firestopping, plus man-hours for installation of each component at local union rates, subcontractor overhead and profit, and tax. Schedule 40 PVC pipe tn sizes ranging from Vi" to 8" was used for all four comparisons.
Two firestopping systems were used to prepare the estimates:
3M Fire Barrier (the proprietary system): Pipe wrapping, aluminum foil tape and caulking.
USG Thermafiber (the generic system): Ban insulation in walls, but applied around pipe then sealed with smoke sealant.
CODE APPROVALS
All three model building codes permit the use of PVC pipe, provided the appropriate plumbing code allows its use. Both the Standard (SBCCI) and National Building Code (BOCA) incorporate plumbing codes that do not restrict the use of PVC pipe. In areas where the IAPMO code is the adopted plumbing code. PVC pipe currently is restricted to use in combustible construction less than seven stones in height Some large cities have their own plumbing codes, and permitted uses for PVC pipe may vary in these cases

3M Fire Barrier (the proprietary system): Pipe wrapping, aluminum foil tape and caulking.
USG Thermafiber (the generic system): Ban insulation in walls, but applied around pipe then sealed with smoke sealant.
All three model building codes permit the use of CPVC pipe, provided the appropriate plumbing code allows its use. Both the Standard (SBCCI) and National Building Code (BOCA) incorporate plumbing codes that do not restrict the use of CPVC pipe. In areas where the 1APMO code is the adopted plumbing code, CPVC pipe currently is permitted on an exception basis only. Some large cities have their own plumbing codes, and permitted uses for CPVC pipe may vary in these cases.
