Abstract

In a study at the National Bureau of Standards (NBS) , funded by the Department of Housing

and Urban Development (HUD) , methods for inspecting mobile homes to identify performance

problems, recording the problems and analyzing the problem data were developed. Maintenance

work orders for 2881 mobile homes, a part of 12,500 provided by HUD for emergency housing in

the aftermath of Hurricane Agnes, at Wilkes-Barre , Pennsylvania, were reviewed and computer

coded by an inter-disciplinary team of engineers. Also, performance data were obtained from

State and other Federal agencies for over 967 privately owned mobile homes. A second task was the field inspection of 257 mobile homes to assist in the determination of the causes

and consequences of the problems identified in the data acquisition task. Computer techniques were developed to process the data and print out problem summation tables, graphs

to establish trends, compile data on obvious problems and ferret out those problems which

may not be obvious. This first report documenting the data acquisition and analysis methodology will be followed by a series of reports which will present results and relate them to current standards, the regulatory and insurance processes.

1,0 INTRODUCTION

1.1 Objectives of Project . Recently, many people and groups have questioned the effectiveness of mobile homes in providing safe, adequate and low-cost shelter. Although life-safety

aspects such as fire safety and wind damage receive the most publicity, functional characteristics appear to be of broader concern to mobile home owners. It is recognized that mobile

homes are subjected to conditions prior to occupancy, e.g., manufacturing, transportation and

sitingl^/ which differ greatly from conventional housing. Because of these unique conditions,

mobile homes exhibit performance problems which may not be encountered in other forms of

housing. Unfortunately, there is a limited amount of organized documentation of these perfor- mance problems, making it difficult to pinpoint what aspect of the mobile home production

process (standards, regulatory, manufacturing, transportation or siting) could be at fault.

There is also limited data to assist in evaluation of the durability and maintainability as- pects of mobile home construction.

To investigate these recognized problems, a project funded by the Office of Policy Development and Research of the Department of Housing and Urban Development (HUD) was structured

around the following objectives:

A. Identification and documentation of significant mobile home performance problems.

B. Determination of the relationship between the identified performance problems and

provisions of

:

1. ANSI A119.1 Standard for Mobile Homes.

2. Inspection, Quality Assurance, and Regulatory Processes.

3. Mortgage Insurance Requirements.

C. Determination of problem areas requiring additional mobile home research.

1.2 Mobile Home Industry . Mobile homes have risen to a position of dominance in housing

in the United States representing approximately one-fifth' of new housing starts in each of

the past five years. The production of mobile homes increased dramatically from 100,000

units in 1960 to around 600,000 units in 1973 (Figure 1). In the under $20,000 new housing

market, mobile homes represented 96% of the houses produced in 1973 which is somewhat higher

than the rate for years 1968 to 1972 (Figure 2).

The growth of the mobile home industry has resulted from its ability to produce a product

which meets the price requirements for lower income groups during a period of rising costs

for all types of housing. Young families and an increasing number of retired persons are creating a demand for lower-cost housing containing the modern amenities. The growth of the

industry has also been helped by the willingness of the commercial banking system to extend

loans to customers and dealers for the purchase of mobile homes.

The basic dimensions of mobile homes can vary in width from 8 feet to 16 feet and in length

up to 70 feet. Flexibility in home configuration can be obtained with units designed with

expandable portions, and single wide units designed to form double wides when placed adjacent

to one another, or in some cases, triple wides. The width of the units is an important dimension because of its impact on transportation over the highways. The distribution of mobile

home shipments for the years 1971, 1972 and 1973 as a function of width is shown in Figure 3. The percentage of shipments of 12-foot wide units has been decreasing somewhat during the

period while shipments of 14-foot wides and double wides have increased. The number of 8, 10

and 6-foot wides and expandables2/ is a small portion of total shipments. It is anticipated

\l Siting encompasses placement and leveling the mobile home on its foundation, installing

steps, skirting and connecting utilities.

TJ Units designed with sections which either push-out or swing out from the mobile home at the site.
that 14 and 16 foot wide mobile homes will Increase their share of the total market in

future years as more states relax highway transport width limits.

1.3 Mobile Home Standards . The mobile home industry, is unique within the building industry in that there is a single standard, ANSI A119.1 Standard for Mobile Homes [1] 3_/> which covers the major aspects of the mobile home building process, i.e., construction,

electrical, plumbing and mechanical. Park considerations are included in ANSI A119.3

Standard for Mobile Home Parks [2], These standards are developed using the concensus

process by ANSI Committee A119 on Mobile Homes and Recreational Vehicles. The committee

is sponsored by three industry groups (Mobile Home Manufacturers Association, Trailer

Coach Association, and the Recreational Vehicle Institute) and the National Fire Protection

Association. Committee membership is drawn from the mobile home, recreational vehicle, and

related industries as well as from state and federal governmental organizations, consumer

groups, trade associations, insurance industry and other interested groups.

States that have legislated mobile home construction requirements have most frequently

adopted ANSI A119.1 as a whole or have used it as a model upon which to base their standards.

As of June 1, 1974, 45 states have adopted or are in the process of adopting ANSI A119.1 or portions thereof.

1.4 Mobile Home Regulatory Process . Because of the nature of the product and its manufacturing process, the regulatory process for mobile homes is unique to the housing industry.

Enforcement of a mobile home standard is the responsibility of the state in which it is

manufactured and generally includes certification that the construction meets the codes re- quirements and inspection of the product in the , factory to insure that the approved design

is met.

There are two basic regulatory programs which are used separately or in combination

by the states. Some states set up mobile home agencies to enforce regulations while others

utilize independent third party organizations to perform such services. A typical combination would be for the states to set up an in-house agency for plan certification while

employing a third-party to perform In-plant inspection. A recent National Bureau of

Standards publication by Cooke, Tejuja, Dikkers and Zelenka [3] outlines the various programs in use by the 50 states as of early 1974. This report establishes the fact that

there is considerable legislative activity at the state level in the mobile ^home and

manufactured building regulatory field.

1.5 Project Approach . In order to address the stated objectives, the project was organized

around three basic tasks.

Task 1 - Collection and Analysis of Existing Mobile Homes Performance Data

Collection of data from Federal agencies. State regulatory agencies, and con- sumer groups to reflect trends and Identify functional failures and major problem areas.

Task 2 - Field Inspection of Mobile Homes

Inspection of mobile homes in the field in an attempt to determine the causes

and consequences of the performance problems documented in Task 1.

Task 3 - Summarize Data and Develop Conclusions

Synthesize data obtained in Tasks 1 and 2 to fulfill the other objectives of the

project. Develop additional source documents in the standards and regulatory areas.

3/ References are listed at end of report.
A. Regulatory Study - Visit State agencies regulating mobile homes and

manufacturers within that state to determine specific effects of the

regulatory programs. In addition, visit selected states representing a cross section of typical programs such as state operated programs, third

party programs, and combinations of the two used throughout the United

States

.

B. ANSI A119.1 Standard for Mobile Evaluation Study - Prepare a document

outlining changes in the specific requirements of the ANSI A119.1 Standard

from the 1969 edition through the 1972, 1974, and 1975 editions.

2.0 DATA ACQUISITION PROCEDURES

2.1 Introduction . The mobile home data obtained consisted of maintenance records, consumer

complaints, on-site inspection reports, etc. and data resulting from NBS field team inspections of mobile homes. Because of the varying nature, location and availability of these

data sources, procedures had to be established which would provide a cost-effective and

timely means of data retrieval.

In the planning phases of the project, it was anticipated that the major portion of

performance data would come from mobile homes used by HUD as emergency housing following

the 1972 Hurricane Agnes disaster. Later, when it became evident that these units were

all manufactured at approximately the same time and were put into use under emergency

conditions, it was decided to seek additional data sources in order to obtain a more re- presentative data base. These added sources included other Federal agencies, state regulatory agencies, consumer groups, and private owners of mobile homes.

2 . 2 Available Mobile Home Performance Data

2.2.1 HUD Data (Hurricane Agnes Mobile Homes) . As a response to Hurricane Agnes, HUD setup and maintained a records system which allowed an evaluation of the performance of the

mobile homes used as temporary housing.

2.2.1.1 HUD Response to Hurricane Agnes Disaster . The Department of Hosuing and Urban

Development purchased approximately 18,000 mobile homes that were used as temporary housing

for victims of the Hurricane Agnes disaster which occurred in June, 1972. The largest con- centration of these mobile homes was in the Wilkes-Barre , Pennsylvania area where they

totaled approximately 12,500 units. The urgent need for mobile homes was such that large

quantity purchase contracts were negotiated and awarded in a minimal time period to manufacturers and dealers with the primary requirement being the earliest possible delivery

date. Since this immediate need exhausted the local market of mobile homes, manufacturers

and dealers from as far south as Florida and as far west as Texas, supplied mobile homes to the disaster relief effort.

The exigencies of time, in many instances, precluded specifying that these mobile homes

meet the requirements of standards such as ANSI A119.1 or of the code of the state in which

the home was purchased.

The processing procedure for incoming mobile homes in the Wilkes-Barre area was as follows. Three large staging areas were established at convenient locations in the city,

namely the Red, White, and Blue staging areas (See Figure 4). Each mobile home that entered

the area was delivered to a particular, previously assigned staging area. Upon arrival at the staging area each mobile home was visually inspected to determine if it could be assigned

for use immediately or if some repairs were needed as a result of manufacturing omissions or possible transport damage. Repair crews were available to make the mobile homes "field

ready" after which the homes were delivered to either private sites or to the various mobile

home parks that were being constructed in the area. Field crews were then given the task of

blocking and leveling the units, hook-up of all utilities, and installing preconstructed

3
wooden stairs at the entrance doors and installing skirting on the mobile homes.

As soon as the mobile homes were available for occupancy, families were assigned and

moved into them. The occupants then had the use of these units until their pre-disaster

dwellings were rehabilitated or until permanent housing became available. Any maintenance

or repairs to the mobile homes needed during occupancy was accomplished by HUD repair crews

or designated contractors. The occupant simply had to call the HUD Maintenance Office giving

his or her name and address along with the HUD number assigned to their mobile home and re- quest the needed repairs. A record of the call was made by filling out a repair work order.

These repair orders were then assigned to maintenance crews for disposition. Upon receipt

of the order, the maintenance crew would proceed to the mobile home and make the necessary

repairs noting the extent of the repair, the time required, and materials used for each

ordered repair. This copy of the repair order was then returned to the maintenance office

and placed in a file folder that had been established for each mobile home under the HUD

identification number. A typical "maintenance work order" is presented in Appendix A,

(Exhibit 1) . Using this procedure a complete history of all repairs made to each mobile

home while occupied or available for occupancy (through park manager initiated maintenance

orders) was established.

As permanent housing became available to the initial occupants, the units were either

reassigned to new tenants or kept available on a standby basis. As the need for temporary

housing declined each empty unit was evaluated by HUD inspectors to a set of criteria

established by HUD so that a disposition decision could be made. Typical forms used in this

"criteria inspection" are also presented in Appendix A, (Exhibit 2) . The disposition options were as follows: refurbish the unit and store it for future disaster use; declare it surplus

and place it on the market for transfer to other federal government agencies that expressed

a need; or declare the unit unusable and allow it to be salvaged for repair of other units.

The option selected generally depended on the dollar outlay required to refurbish the mobile

home. A small number of units were sold to the occupants that had resided in them and

indicated a desire to purchase. The Kaminski storage area (See Figure 4) was established

to accommodate the vacated mobile homes as each of the parks were deactivated and until

final disposition of the units could be completed. This storage area was the location of

the NBS field team inspection operations described herein.

2.2.1.2 Data Acquisition Procedures . The two major sources of data used in this phase of

the project, maintenance and refurbishment data (Appendix A - Exhibits 1 and 2), were

brought to NBS on loan from HUD. Only data for approximately 10,000 units of the 12,500

total were included since HUD required that files for all active mobile homes (those still

occupied) must remain in Wilkes-Barre . •

The other source of data was HUD Finance Department records which could not be taken

from Wilkes-Barre. It was necessary to have access to these files since they contained

valuable mobile home identification information such as manufacturer, serial number, state

and year of manufacture, purchase cost, number of occupants and length of occupancy. A

former HUD staff member with experience on the Hurricane Agnes Disaster Team was placed

under contract to extract information from these files and also to provide liaison for all

NBS Wilkes-Barre activities.

2.2.1.3 Sample Selection Criteria . As previously noted, the files obtained from WilkesBarre had a numbering system which uniquely identified each mobile home. The system was based on an eight digit number with the first four digits being the contract number and

the last four digits being the number of the mobile home purchased under that contract.

For example, the mobile home with the HUD number 3092-0100 represents unit 100 purchased

under contract number 3092. The files were ordered consecutively by HUD contract number

and by unit number within each contract. The number of mobile homes within a contract

varied from one to several hundred.

Since it would not be possible to evaluate data for the entire 10,000 units, a method

of selecting a representative sample without bias was devised by the Statistical Engineering

Section of the NBS Institute of Basic Standards. This method consisted of randomly selecting 500 units at a time without replacement. A random number table was generated and used

4
to select a 3000 unit sample (in 500 unit blocks) from the numerically ordered files for

detailed evaluation. The sample was deemed to be both manageable and representative of the

10,000 unit population. The vast majority of the problems were gleaned from the maintenance

work orders; only about 10% of the problems were provided by the refurbishment data. The

maintenance work orders for these 3000 units were separated to facilitate computer coding

of the performance problems. Refurbishment data were found for only 1560 of these 3000

units because a large amount of this data had been shipped from Wilkes-Barre with the mobile

homes to other storage locations throughout the country.

2.2.2 Privately Owned Mobile Home Data

2.2.2.1 General . Acquisition of performance data on mobile homes from sources other than

HUD was a basic requirement of the project. It was felt that these data from privately

owned mobile homes were needed to augment the performance data obtained from Wilkes-Barre.

Consideration of the two data sources should enhance the general applicability of the overall study results and tend to minimize any variations caused by the differences between

Federal government and private procurement and certification procedures.

2.2.2.2 Data Source Selection Criteria . Since the study resources were finite and limited,

it was decided early in the planning phase to concentrate on those states with large mobile

home populations such as California, Texas, Florida, etc. Using this approach it was possible

to gain access to the maximum quantity of mobile home performance data for a minimum ex- penditure of time and money. It is recognized that this data acquisition method does not

render results that are statistically reliable for the total mobile home population of the

U.S. On the other hand, the results are generally representative of the performance problems encountered by mobile home users. The performance problems identified in privately

owned mobile homes can be useful in ferreting out the major problems and their relation to the mobile home standard (ANSI A119.1) as well as to regulatory procedures.

Initial emphasis concentrated on the state agencies responsible for mobile home regulation and/or administration. Table 1.2.2 from reference [3] was found to be extremely useful

as a guide to the location and personnel of the state agencies regulating mobile homes.

These agencies varied widely from state-to-state and were attached to building code, consumer

affairs, community development, labor or motor vehicle organizations. In addition to the

state organizations, other agencies with potential data banks on mobile home performance

wer,e contacted. These included Federal agencies such as the Veterans Administration, mobile

home owners organizations, privately owned mobile home parks with rental units, and various

consumer groups. There was no attempt to interview private mobile home owners on an individual bases.

2.2.2.3 Data Acquisition Procedures . The initial contact with the various potential

sources of mobile home performance data was made by a telephone call to the organization.

The scope of the project was discussed and a request was made for the organization's

cooperation in making data available to NBS. The request included forwarding NBS a sample

copy of two or three documented cases of mobile home performance problems from their files

along with an estimate of the total number of such cases available. As a follow-up action

to the phone call, a letter was transmitted to the individual contacted recapping the phone

conversation with a request for sample cases and other information. As a result of the above

procedure, responses including sample cases were received from 14 sources as listed in

Table 1.

After initial discussions with agencies having data, it became clear that most of these

agencies did not have sufficient staff to extract the data needed by NBS from their mobile

home files. As a result it was decided to send project field teams to those sources which

appeared to have maximum quantities of mobile home performance problems on file. Visit

arrangements were coordinated with the selected source and usually a two man team made the

visit and retrieved the data. Normal procedure on arrival at the source's office was to review the total mobile home file available, and select a representative sample of cases where the file was too voluminous to copy each docket. For each case selected a copy was

made of the owner's initial complaint letter and, when available, the agency follow-up

5
inspection report. In addition, mobile home identification data were recorded for each case using the form shown in Exhibit 3, Appendix A. Using the above procedure a total of 967

mobile home performance problem cases were obtained as summarized in Table 1.

2.3 Field Inspection Data

2.3.1 Selection Criteria . It became necessary to establish a selection criteria for mobile

homes because of the large number available both in the HUD stockpile and in the private

sector.

2.3.1.1 HUD Units . Initially it was planned to select units for field inspection at WilkesBarre that were included in the 3000 mobile home sample undergoing performance data analysis

(Section 2.2.1.3). It became evident very early in the field inspection operations that this

type of procedure would not be practical because of the difficulty encountered in locating

specific units in the large rapidly changing inventory of mobile homes at Wilkes-Barre.

Units were being moved on a 24 hours per day basis in and out of the storage area making it

virtually impossible to obtain an accurate current Inventory or locate specific units.

Additionally, the inventory was down to 2000 units from the initial 12,500 mobile homes used

in the disaster effort.

As a result, the procedure adopted was simply to select units at random for field inspection with no attempt at pre-selection (random sampling). There was an attempt to inspect

units of as many different manufacturers as possible and to skip duplicate units, A total

of 237 units wera field inspected at Wilkes-Barre.

While the large concentration of mobile homes in the Wilkes-Barre area as a result of

Hurricane Agnes created an excellent opportunity for field inspection of mobile homes, some drawbacks were apparent. All of the units had been manufactured at approximately the same

time (1971-1972) and many were transported over unusually long distances and had been sited

under emergency conditions. The temporary nature of the mobile home parks and private site

placements created problems that would not have been encountered under normal circumstances.

The conditions were further complicated by the fact that the occupants were living in mobile

homes by necessity and not by choice. Also, the performance data gathered at Wilkes-Barre

by the field inspection team represents an atypical condition in that the team was looking

for and recorded the most extreme probjems encounted.

2.3.1.2 Privately-Owned Units . The peculiar conditions related to acquisition, siting and

occupancy of the HUD Agnes mobile homes made it necessary to inspect mobile home usages under more normal conditions. The field study was enlarged to include units from the private

sector.

Because of the difficulties of locating and arranging inspection of individually owned

mobile homes, sources were sought out which would allow access to a large number of units

at a single location. Also, it was desirable to have access to purchase specifications

and maintenance records of the homes inspected. Four such sources were located at various

locations in the United States.

A privately oxmed mobile home park in Lexington Park, Maryland, consisting of 25 new single

wide (12 foot wide) units which had just been installed and occupied, was inspected. These were duplex rental units and had been purchased to a specification established by the owner

and had unique construction characteristics. Each unit was divided into two living areas with separate bath, kitchen and sleeping facilities.

Mobile homes constructed in 1962 and 1965 were inspected at Warren Air Force Base in

Cheyenne, Wyoming to obtain data which could be related to durability. These units which

are being used as housing for families of construction personnel have been moved eleven

times over an average distance of 650 miles each move. The mobile homes were purchased under a specification prepared by the Air Force and have been maintained for the Government by a

6
private company since purchase.

A private mobile home park containing 200 mobile homes manufactured in 1971 and 1972 was

inspected in Montgomery, Alabama. These units were owned by the Alabama Farm Bureau (not

state affiliated) and rented to Air Force personnel attending 12 week courses at Maxwell

Air Force Base. In addition to inspection of these units, maintenance records for one twelve week occupancy period were obtained along with refurbishment data for the life of

each unit.

Five mobile homes being modified under a HUD Grant for use by handicapped students were

inspected at St. Andrews College in Laurinburg, North Carolina. These units were obtained

by the College from the HUD Agnes stockpile and purchase, maintenance, and refurbishment

data for the units were available.

2.3.2 Interdisciplanary Team Approach . The mobile home field inspection team consisted of

NBS staff members with expertise in various phases of the building process. The team members

had many years of experience in their particular area of the building process and also had

some experience in the mobile home field. The team consisted of a structural engineerproject manager and five other members with engineering expertise in the fields of materials,

plumbing, heating, electrical, and fire technology.

Prior to initiation of the field inspection task, the team members became familiar with the

construction of mobile homes by visiting several mobile home manufacturing plants including

one that produced average quality units as well as a plant that produced a superior product.

A visit to a manufacturer of mobile home frames and metallic roll roofing was also included

in the familiarization program. These plant tours were very instructive and the plant

managers extremely helpful and cordial in their efforts to explain the manufacturing processes used for producing mobile homes.

In addition to the plant tours, the Mobile Home Maintenance School established by HUD in

Wilkes-Barre for training of repair crews, was visited by the field inspection team. These

training courses for maintenance of heating, electrical and plumbing systems were established

by HUD to increase efficiency of the repair crews responsible for maintenance of the disaster

units.

2.3.3 Development of Field Inspection Techniques . In conjunction with the plant inspections

and maintenance shcool visits additional training was afforded the field inspection team by

visits to the Red and White Staging areas at Wilkes-Barre (See Figure 4)

.

The White Staging Area was the "grave yard" for units that had been damaged beyond repair.

These units had been either damaged in transport, during placement at the mobile home parks

and private sites, or during occupancy. Several units that had been destroyed by fire were

also stored here. These units were being salvaged of all usable parts for repair of other

mobile homes. Inspection of these units made it possible to observe structural framing

techniques (including roof trusses), plumbing trees, wiring techniques, heat duct assemblies

and insulation, and vapor barrier installations. Many units had been damaged so severely

that it was not necessary to remove paneling for inspection purposes as large portions of

the paneling had already been removed or destroyed.

At the Red Staging Area eighteen mobile homes were set aside for use by the field inspection

team. While some of these units had been declared unsuitable for further use by HUD because

of damaged or inadequate construction such as short outriggers, aluminum wiring, bent frames,

excessive refurbishment costs, etc., most were in good condition. Permission was granted to NBS to perform any type of destructive evaluation on these units that the field inspection

team- deemed appropriate including complete dismantling of the unit if necessary.

The type of "destructive disassembly" inspection procedures employed included the selective

removal of ceiling and wall panels (interior and exterior), flooring and undercarriage

weather protection barrier, to observe workmanship, structural framing, insulation, vapor

barriers, wiring methods and plumbing trees. Samples of the materials such as cabinet doors,

7
wall paneling, ceiling materials, electrical and plumbing parts and fixtures were removed

and returned to NBS for study.

Since it would not be possible to "destructively" inspect any more of the 2000 units at Wllkes-Barre and at private sites,- it was necessary to develop "non-destructive" inspection

procedures. Evaluation of the eighteen units indicated that it was difficult to remove and

replace interior and exterior paneling easily without damage to the paneling. Also, the

plumbing trees and heating distribution systems could not be thoroughly inspected without

laboriously removing paneling, flooring, or undercarriage weather protection which would be

difficult to replace in a like-new condition. The roofing system including metallic

membrane, truss construction, insulation, vapor barrier and finished ceiling is unitized.

The minimum possible non-destructive method of evaluation would require the removal of

the furnace vent stack in order to inspect the immediate area of its penetration through

the roof. This vent stack would then have to be replaced and resealed from outside the

roof to eliminate water leakage potential.

Consequently, the "non-destructive" inspection procedure used for the vast majority of mobile

homes became a visual inspection without the removal of permanent construction. Partition

construction could be observed in unfinished closets, water heater compartments and furnace

enclosures. Plumbing inspections had to be confined to the hot water heater compartment,

under kitchen and bathroom sinks or at washer hookups. Heating system evaluation was confined to the furnace compartment and by removal of floor registers. The electrical distribution system could be evaluated at the load center and by removal of switch plates and

duplex outlet covers.

2.3.4 Data Recording Techniques . The data recording techniques used in the field inspection effort were both written and visual. Inspection forms were filled out on each mobile

home inspected. These forms included identification, structural, plumbing, heating and

electrical information. A photographic record was also made of each unit that included

any unusual conditions encountered or failures that were evident. These inspection fprms

and photographs along with the maintainence and refurbishment data then formed the data

base for evaluation of the individual mobile homes examined during the field inspection

effort.

2.3.4.1 Inspection Form Development . Since "destructive" inspection was precluded, except

for the few units described earlier j a "non-destructive" or visual inspection procedure

was developed to record all available information.

A four step approach to the development of the inspection forms for mobile homes was followed. First, each member of the inspection team prepared a list of all information within

his particular field of expertise that would be advantageous to know in evaluating the

performance of the mobile home. The second step was to list all information that could

possibly be observed in an actual non-destructive visual inspection based on the experiences

gained in the destructive evaluation experiment. The third step was to collate these two lists with the ANSI A119.1 standard and thereby establish what could be observed as standard

variances. The fourth step was to develop an inspection form sheet for each discipline

that would evaluate these standard requirements with the available information in a simple

check list type format. A typical set of inspection form sheets used is included in

Appendix A, (Exhibit 4)

.

Since an objective of the project is the evaluation of ANSI A119.1 Standard for Mobile

Homes, the data retrieved on the data forms is related directly to specific sections of

the standard (1974 edition), where possible.

2.3.4.2 Photographic Documentation . To augment the inspection form data and to provide

a cross check for future evaluation, a photographic record of each mobile home inspection

was made. The first photograph taken was of the front of the mobile home that clearly

identified the unit by its unique identification number. Each succeeding photograph

taken was of that particular unit and included code violations, component or system

failures and any other unusual conditions related to performance that existed on the

interior and exterior of the unit. Typical photographic documentation for a mobile home

8
is shown in Appendix B.

3.0 DATA ANALYSIS METHODOLOGY

3.1 General . An initial project task was to develop a methodology for data analysis which

could be used to evaluate the vast amount of mobile home performance data acquired from the

various sources. Because of this large quantity of data, it was apparent that computer

techniques should be used. It was necessary to develop a coding system whereby a reviewer

could record the problems to form a data base for analysis. The data analysis system

developed consists of a Problem Catalog which lists a broad range of performance problems,

coding techniques to record the problems and computer programs to organize and process the

data. In developing this system the following guidelines were followed:

1. The data analysis system should be easily understood and capable of being used with

a minimum possibility of error.

2. Data analysis system should be readily expandable and not sensitive to change.

3. Data analysis system should be easy to check.

3.2 Problem Catalog Development . The Problem Catalog contained in Appendix C is composed

of two major sections: (1) Mobile Home Identification Data, and (2) Performance Problem

List.

The Identification Data Section provides a method of recording information describing

characteristics of each mobile home such as manufacturer, state and year of manufacture,

serial number, seal or seals of approving agencies, dimensions, construction characteristics,

etc.

The Performance Problem List is organized into three subsections which permits categorizing

of the mobile home performance problems encountered. (Figure 5):

A. Problems Related to ANSI A119.1 Standard for Mobile Homes

B. Routine Maintenance Problems

C. Appliance and Equipment Problems

The Performance Problem List was developed through a process of evolution; as new problems

appeared in the performance data new items were added to the list. The ANSI Standard A119.1

subsection represents virtually the entire 1974 edition of the Standard (NFPA No. 501B-1973),

with coding symbols being assigned for appropriate paragraphs. In the case of the Electrical

(Part E) , Plumbing (Part C) , and Heating (Part D) sections of the standard the paragraph

numbers and key words in the catalog appear in sequential order, just as they do in the

standard. Construction (Part B) differs in that the catalog is organized around major con- struction components, such as roof, floor, walls and doors etc. Therefore, some paragraph

numbers which pertain to several components are repeated and are not necessarily in sequence.

It became apparent in the early stages of data analysis that many of the problems encountered

in the Wilkes-Barre files could only be related to ANSI A119.1 in a very general way. While

most of the maintenance work orders identified the type and location of problem and stated

the manner in which it was corrected, some were lacking in necessary detail. For example,

a water leak may have been recorded without any indication as to where in the mobile home

it occurred or what was done as a repair. It should be pointed out that much of these

data were recorded under emergency conditions with no thought that they would be later

used in this project.

In view of these shortcomings, and because of the need to preserve the detail of the problems recorded, it was decided to create a Routine Maintenance Subsection and an Appliance

and Equipment Subsection which would be separate from the ANSI A119.1 section. If there

9
was not sufflei©nt information to record a problem undtr an ANSI A119,l heading it was placed in one of these other subsections. These two subsections of the catalog were also

developed in an evolutionary manner. The initial organization was established by a con- census judgement of the project staff, a pilot survey of the maintenance records for about

fifty Wilkes-Barre mobile homes and a review of Wilkes-Barre mobile home performance problems produced in a separate study conducted by the HUD Office of Policy Research and

Development. When a previously unreported problem occurred, a new coding symbol was added to the appropriate section, continually increasing its coverage.

The Routine Maintenance Subsection was organized under the same general headings as the

ANSI A119.1 Subsection; i.e. construction, plumbing, heating, and electrical. The Appliance

and Equipment Subsection was grouped by appliance; i.e. furnace, range, hot water heater,

refrigerator, exhaust fan and smoke detector. Since components of each appliance are listed,

it is possible to record as high a degree of detail as the data permitted. Furniture problems and the occurrence of a fire in a mobile home were recorded under a category separate

from the three subsections.

A problem level concept is employed to organize and assist in the evaluation of the data.

These levels are used for organizational purposes only; they do not Indicate or imply the

degree of importance of the problems. Figure 5 illustrates problem levels 1, 2 and 3 and

Figure 6 isolates ANSI A119.1 (Construction) to illustrate levels 2 through 7. The number

in the extreme right hand column of the Problem Catalog in Appendix C indicates the problem

level for each item.

3.3 Problem Coding Techniques . The development of the Problem Catalog and coding techniques were interdependent in that they were evolved concurrently. The design of the coding techniques were influenced by the project schedule, flexibility of adding new items to the

Problem Catalog, available facilities for preparation of input data and the minimization of

computer coding errors. The latter could be most readily accomplished by a coding form

which could be read electronically, producing a magnetic tape for computer input. This

would eliminate, of course, the human error Inherent in the conventional method of preparing

computer input data by keypunching computer cards. Two systems are currently available

wherein it is possible to transcribe. data from coding forms directly to magnetic tape. One,

the Film Optical Sensing Device for Input to Computers- (FOSDIC) system, is well developed and

has been used by the Bureau of the Census for many years; the second, the Optical Character

Recognition (OCR) system, is limited for handprinted alpha-numeric characters. Although the

FOSDIC and OCR systems are attractive from the point of view of minimizing keypunching errors, they do not satsify any of the other criteria. Both systems would take at least three months

to develop and have, the forms printed; once the forms were printed, it would be very difficult

to make additions or effect changes. Additionally, both systems can only be serviced at a limited number of facilities. In view of the above, it was decided to use the conventional

approach of filling out coding sheets and keypunching cards for computer input.

The coding technique selected for use in conjunction with the Problem Catalog is designed

to minimize errors in filling out computer coding sheets'. The standard computer card is

separated into eight fields of ten spaces each as shown on Figure 7. The first field is

used to identify the mobile home; H 3092-0100 in the case shown refers to HUD unit 3092-0100.

Each source of data has a unique identification letter in the first space of this field.

Identification data, other than mobile home number, and problem data are recorded in fields

2 through 8.

There is an alpha-numeric coding symbol in the Problem Catalog for each problem or piece of

identification information which is entered by a reviewer on a computer coding sheet Figure

7), using contiguous fields (i.e. there should be no blank fields between the first and

last entry). While the coding symbols in the ANSI A119.1 subsection are tabulated exactly

as shown, the numeric part of each coding symbol in the Routine Maintenance and Appliance

and Equipment subsections can be either: 1. (adjust), 2. (repair), or 3. (replace) depending on the type of problem (Appendix C) . For example, the repair of a kitchen faucet

assembly would be recorded as NPKA2., while the replacement of the same component would be

NPKA3. Entries in field 2 through 8 can be made in any order and if more than one card is

10
required, the identification number would be repeated in field 1 of succeeding cards. The

order of the cards in the assembled deck is unimportant since they can always be sorted by

identification number in field 1.

As an example of the coding technique consider the following problems and the resulting

code entries on Figure ^.

The personnel who reviewed the files and filled out the data sheets were all engineers

or highly skilled technicians. The field inspection team formed the nucleus of the file

review team. All the technical disciplines required to effectively review the files were

represented on this team. The team worked as a group, so that everyone would benefit from

discussions concerning the proper coding symbols for the problems found in the files. Also,

as new coding symbols were needed, they could be readily formulated and distributed to the

team. ^

3.4 Computer Techniques . Because of the vast amount of collected mobile home performance

data (approximately 32,000 reported problems), computer techniques were used for sorting,

combining blocks of data and other data processing needs. The system selected for coding

performance problems readily lends itself to this because each element of data has a unique

permutation of alphanumeric characters. Prior to manipulating the data, once it was in

the computer, an accuracy check of the data was made to eliminate coding form entry and

keypunch errors. Several programs were written to process the data and printout out tables

and plots once the data had been verified.

3.4.1 Data Verification Programs . Since keypunching of cards was the most error prone

step in the recording of problems, a computer program was written to printout all coding

symbols which were not in the Problem Catalog. The incorrect coding symbols on the printout were checked against the coding form and corrected if possible. This checking procedure

reduced the coding symbol discard rate to less than 1 percent of the over 30,000 problems

recorded.

A particular checking problem occurred in recording performance data for the 3000 unit HUD

sample described in Section 2.2.1.3. This sample was selected from 10,000 files shipped

from Wilkes-Barre to NBS. The 3000 unit numbers selected for analysis were transcribed

onto computer coding sheets and keypunched to provide a check list for data input to the

computer. The corresponding files were located and reviewed by the data analysis team. Because of human errors inherent in the manual processing of Wilkes-Barre files, it was

not possible to locate files for approximately 4% of the 3000 units in the sample which

resulted in a final total of 2881 units for the sample.

3.4.2 Problem Summation Programs and Graphical Presentations . Data processing programs were developed to establish trends, compile data on obvious problems, and ferret out those

11
problem areas which may not be obvious.

The most important of these is a program which prints out summations of problems relative

to the levels within the Problem Catalog. This program processes a given data base and

instructs the computer to print out summations and percentages for levels of problem

refinement (Appendix D)

.

Once the data bases were established, computer programs were developed to print tables,

graphs and histograms to assist in the evaluation of the data. These included tables

relating data such as; (1) year of manufacture versus number of units in the data file,

(2) width versus number of units in the data file, (3) state of manufacture versus the

number of units in the data file, (4) seal of approving agency versus problems versus number of units in the data file. These tables are illustrated in Appendix E along with- a typical computer plot developed for seal of approving agency versus average number of

problems per mobile home. These preliminary data are for illustrative purposes only and

not for analysis. This indicates the potential of the computer techniques which will be

fully utilized in specific aspects of data analysis as required in later reports.

3.5 Application of Methodology to Various Data Bases . The application of the Problem

Catalog and data processing techniques has been discussed for the HUD Hurricane Agnes

mobile home data (Section 2.2.1). The privately owned mobile home data (Section 2.2.2) were handled in exactly the same manner except it was not necessary to select a small sample

of units from a large data base. Reported problems for all 967 mobile homes were included

in the data base.

The forms completed during the field inspection of mobile homes, photographic documentation,

and available maintenance and refurbishment data which were available constituted the data

base for the field inspection task (Section 2.3). These data were coded by the Field

Inspection Team using the format of the Problem Catalog.

The three data bases, HUD Agnes data, private data, and field inspection data were maintained separately in computer storage files permitting any type of analysis deemed desirable

by the project staff. Analysis could proceed separately within each data file or selective

combinations of data could be made.

4,0 SUMMARY COMMENTS

This report is part of a HUD funded project to Identify and document significant mobile

home performance problems and to relate them to possible inadequacies in the mobile home

standard, regulatory processes or to insurability aspects of concern to HUD. The data

acquisition and analysis methodology documented herein shows a unique approach used to solve a complex problem of data retrieval and analysis.

The results and conclusions of the project tasks outlined in Section 1.5 of this report

will be developed in future reports planned for this project.

16. ABSTRACT (A 200-word or less (actual summary of most si^ificant information. l( document includes a significant

bibliography or literature survey, mention it here.)

In a study at the National Bureau of Standards (NBS) , funded by the Department of

Housing and Urban Development (HUD) , methods for inspecting mobile homes to identify

performance problems, recording the problems and analyzing the problem data were developed. Maintenance work orders for 2881 mobile homes, a part of 12,500 provided by HUD

for emergency housing in the aftermath of hurricane Agnes, at Wilkes-Barre , Pennsylvania

,

were reviewed and computer coded by an inter-disciplinary team of engineers. Also,

performance data were obtained from State and other Federal agencies for over 967 privately owned mobile homes. A second task was the field inspection of 257 mobile homes

to assist in the determination of the causes and consequences of the problems identified

in the data acquisition task. Computer techniques were developed to process the data

and print out problem summation tables, graphs to establish trends, compile data on obvious problems and ferret out those problems which may not be obvious. This first

report documenting the data acquisition and analysis methodology will be followed by a series of reports which will present results and relate them to current standards, the

regulatory and insurance processes.
