B -- RADON RELATED CONSTRUCTION PRACTICES OF HOME BUILDERS IN 1996 SOL B3E006 DUE 050197 POC Mekeba Brown WEB: NOT AVAILABLE, NOT AVAILABLE. E-MAIL: NOT AVAILABLE, BROWN.MEKEBA@EPAMAIL.EPA.GOV. This contract action is for services for which the Government intends to solicit and negotiate with only one source using the Simplified Acquisition Procedures of FAR Part 13. Scope This statement of work details the data and final report required by the Indoor Environments Division on radon-resistant construction practices of home builders in 1996. Background One key priority for the Indoor Environments Division (IED) of the Environmental Protection Agency is promoting the use of radon-resistant construction techniques in new homes as a means of achieving cost-effective radon risk reduction. Tracking rates of new homes built with radon resistant construction techniques will enable IED to measure progress and reassess strategies for promoting the use of radon-resistant construction techniques. Data on radon-related construction practices has been tracked since 1990. Since then, approximately one million single family homes have been built using radon-resistant construction techniques. Objective IED seeks to obtain a final report with data on the number of homes built in 1996 utilizing radon resistant construction practices. Contractor Tasks 1 . Survey builders and obtain data on at least 0.03% (estimated at 30,000) of all homes built in the United States. Homes should be distributed in the nine census regions in proportions relatively close to proportions in Census Bureau housing start statistics. 2. Obtain data on: a. Subslab preparation b. Radon ventilation systems c. Slab sealing methods d. Percent of houses tested for radon e. Percent of tested houses that needed additional work to reduce radon 3. Prepare and submit one bound and one unbound copy of a final report in accordance with and containing the items listed below. 3.1 The report will contain the following data tables: a. Single-Family Detached Coefficients: Nine Census Regions b. Multifamily Coefficients: Nine Census Regions c. Single-Family Detached Coefficients: 32 State Market Areas d. Single-Family Detached Coefficients By Radon Exposure Zones e. Multifamily Coefficients by Radon Exposure Zones f . Product Usage by Radon Exposure Zone 3.2 Data tables will contain the following data: a. Sample size of housing units built in 1996 b. Type of houses built in 1996 and the percent with radon-resistant features c. Types of foundations used in 1996 and the percent with radon-resistant features d. Radon testing done for new homes with radon-resistant features e. Construction methods and the percent with radon-resistant features f. Methods employed to reduce radon g. Sealing methods used in new construction h. Types of subslab preparation for radon-resistant features I. Size of builder and percent with radon-resistant features 3.3 Responses from large production builders shall be limited to 500 single-family and 500 multi-family homes. 3.4 Copy of questionnaire shall be included in the final report. 3.5 Executive summary report written to also contain: a. Description of survey and methodology b.Comparison of current data with data from previous surveys c. Percentage of starter homes, move-up homes, and luxury homes and average square footage for each type of house d. Number of builders or other entities contacted and response rate e. By region, the percentage of homes sampled compared with the percentage of 1996 housing starts in that region f. Statistical discussion of the estimates 4. Single-family detached unit is defined as a single dwelling unit that does not share any common walls or foundations with another unit. Multifamily housing are structures, three stories or less, containing more than one dwelling unit. Contract End Terms Program Office reserves the right to request changes in the format and/or layout of the final table of data. Final report as outlined above shall be submitted to IED no later than September 30, 1997.
