Stock Number 029-001-01861-4 Preface This bulletin is the first study of private multifamily housing which the Bureau of Labor Statistics has conducted. It provides detailed data on employee-hour require ments by occupation and contractor as well as information on the amount and type of materials and supplies required. Other studies in the series include highways, general hospitals, elementary and secondary schools, private single-family housing, public housing, Federal office buildings, civil works, college housing, and sewer works. Such information enables policymakers to determine the number of jobs, by occupation, generated from a given amount of expenditures for construction. Joseph T. Finn and Frank L. Wood of the Office of Productivity and Technology prepared this bulletin under the supervision of Robert Ball. Larry G. Ludwig wrote the “Nature of industry” section in the Introduction. A summary of the results of this study was published in the January 1975 issue of the Monthly Labor Review. (“Labor and Material Requirements for Apartment Construction,” by Robert Ball, pp. 70—73.) This bulletin elaborates on that summary and presents the survey findings in greater detail. The Bureau wishes to acknowledge the generous cooperation of the Federal Housing Administration of the Department of Housing and Urban Development. The Bureau also wishes to thank the nearly 3,000 general and special trade contractors who provided data for the survey.

Introduction The current program of construction labor requirements studies was started in 1959 when Congress recognized the need for information on the possible employment generat ing effects of various types of construction. Since then, the Bureau of Labor Statistics (BLS) has conducted a series of studies presenting data on the total amount of employment and employee-hours, both onsite and offsite, per $1,000 of construction expenditures and, for some studies, per 100 square feet of space. These studies provide data by occupation which are important in planning for training requirements as well as in determining skill shortages or bottlenecks for various types of construction. Resurveys of a given type of construction over time can contribute information about cost indexes and about estimates of productivity changes for onsite construction labor. Market research analysts and companies manufacturing equipment and supplies are interested espe cially in lists of materials used for construction. Private multifamily (apartment) building is a major component of construction and a prime source of employ ment. Jobs are created not only at the site of construction but also in many manufacturing, trade, transportation, mining, and other industries which furnish the materials and services for construction. The multiplier effect of jobs created by the respending of wages and salaries of workers and profits of contractors is not included in the present study. The study shows (1) the amount of labor time required to complete an average apartment; (2) detailed characteris tics by type of apartment, contractor, and occupation; (3) ratios per $1,000 of cost and per 100 square feet of space; (4) materials used by type; (5) distribution of costs; and (6) total labor requirements generated by the manufacture, sale, and delivery of these materials. Scope of survey The current survey was designed to measure employeehours and the value of materials required for each $1,000 of new private multi-family housing construction in 1971. It was based on a sample of 89 projects of five units or more each in 22 Standard Metropolitan Statistical Areas (SMSA’s) in the continental United States, stratified by geographic location and estimated cost of projects. These projects were selected from Federal Housing Administra tion reports, but the sample was designed to represent all new private, multifamily housing in structures of five units or more in metropolitan areas, where permits were issued during 1969 for 500 dwelling units or more of this type in metropolitan areas. BLS obtained data on onsite employeehours, materials, occupations, contractor operations, and other characteristics from nearly 3,000 general and special trade contractors who worked on sample projects. In cluded were commercial facilities in apartment buildings and enclosed parking areas. Land costs, condominiums, completely prefabricated projects, and structures having fewer than five units were excluded. Survey methods Labor requirements in the construction industry (onsite) were developed from payroll data supplied by contractors. Labor requirements other than for onsite construction were developed by translating the requirements for materials, equipment, and supplies produced in the various industries of the economy (offsite) into the labor expended to mine, process, transport, and distribute them. Estimates were derived by first classifying and aggregating material values by type and then deflating by an appropriate wholesale price index to match the base year of the input-output tables. These deflated values were matched with appropri ate industry sectors in the input-output tables to generate estimates of final demand. Sector productivity factors then were applied to derive employee-hours by industry group. Further details on survey methods are given in appendix A. Nature of industry The industry is divided into two major segments, multifamily and single-family housing. These two types of housing, particularly apartment buildings with over three to five stories, often employ different construction materials and techniques. Also, an apartment project requires larger outlays of labor and capital than single-family housing, and the time between project inception and completion can be as great as 29-30 months.1 Construction time for multi family projects in the survey averaged 57 weeks compared with 21 weeks for projects of the single-family type.2 From 1930 to 1960, multifamily housing averaged only 15 percent of all private housing starts3 whereas from 1956 1Apartment Construction News, November 1966, p. 9. 2Labor and Material Requirements for Construction o f Private Single-Family Houses, Bull. 1755 (Bureau of Labor Statistics, 1972), p. 5. 3Based on Bureau of the Census and National Association of Home Builders data appearing in Journal o f Homebuilding, Novem ber 1970, p. 13. to 1966 it ranged from 9.1 to 33.1 percent, or an average annual rate of change of 13.8 percent,4 according to the Bureau of the Census and the National Association of Home Builders. The steady upward trend, which continued through 1973, increased at an average annual rate of change of 4.3 percent from 1966 to 1973 to reach 44.7 percent of all U.S. private housing starts in 1973 (chart 1). However, the trend was reversed sharply in 1974 when multifamily housing constituted only 33.6 percent of total private housing starts. This downward trend continued into the first quarter of 1975, when multifamily housing provided only 25 percent of the total on a seasonally adjusted basis. Data on housing starts are very closely correlated with data on value put in place, as shown in the tabulation below, which contains statistics abstracted from Bureau of the Census reports.5 Multifamily housing as percent o f— Total private housing starts 1960 ........................ ___ 1965 ........................ ___ 1970 ........................ ___ 1 9 7 1 ........................ ___ 1972 ........................ ___ 1973 ........................ ___ 1974 ........................ ___ First quarter 1975 (seasonally adjusted annual rate) . . . . ___ 20.6 Total value put in place for private housekeeping residential housing 34.6 43.3 43.9 44.4 44.7 33.6 15.2 27.7 39.2 36.7 38.4 40.7 35.8 25.0 26.2 Value put in place went from 15.2 percent of new private housekeeping residential construction in 1960 to 36.7 percent in 1971; the level continued to climb to 40.7 percent in 1973. Both statistical series showed a sharp drop in apartment construction during 1974 which extended into the first quarter in 1975. The BLS survey sample for this study covers multifamily structures containing five dwelling units or more in accor dance with the BLS definition of that universe, which differs in some respects from the definition of the Bureau of the Census in the data shown above. However, the differences do not significantly affect the analysis.6 Structures containing five units or more clearly domi nate the private multifamily housing industry, as shown in the following tabulation: 4 Ibid. Average annual rates o f change are calculated by com pound interest. 5 Based on data in Bureau of the Census, Construction Reports, Series C20, and C30, up through the June 1975 issue. 6The Bureau of the Census includes in its definition structures containing over 10 percent of available footage as townhouses, newly built condominiums or cooperatives, modular units, or rowhouses; BLS does not. The units excluded by BLS, however, are only a small percentage of total 5-or-more-unit construction. Also, the dwelling units in this BLS study are located entirely in metropolitan areas (SMSA’s), while some units in the census data are located in rural areas. Since most multifamily housing is constructed in metropolitan areas, this difference is insignificant.

The majority of five-or-moreunit dwellings are built in low rise buildings. In 1965, for example, 95 percent of new multifamily structures had three floors or less and contained approximately 78 percent of all multifamily dwelling units. The remaining 5 percent were high rise buildings containing 22 percent of the multifamily units.7 In 1971, 94 percent of five-or-moreunit buildings in the BLS survey were low rise buildings. In the North-east region, the only significant variation from the national average, only 48 percent were low rise buildings. The rest of the five-or-more-unit apartment buildings were high rise buildings, confirming the 1965 data that high rises in the Northeast contained approximately 40 percent of the dwelling units. The average dwelling unit in all multifamily structures, which contained 861 square feet in 1960, increased to 1,100 square feet by December 1971.8 This upward trend is evident in the present study which shows an average dwelling unit of 979 square feet in 1971. Also, in 1965, about 92 percent of multifamily housing was constructed in metropolitan areas (SMSA’s),9 in contrast to the 69 percent of all private housing (including single-family) started in metropolitan areas in 1965. In 1971, 1973, and 1974, the figures for all private housing were 73, 73, and 69 percent,10 respectively. The steady growth in demand for multifamily dwellings during the last decade resulted from several concurrent social, technological, and economic factors, including the following: 1. A national trend toward fewer children per family and more families without children decreased the necessity for the larger living space of single-family houses; 2. New households were formed at an increasing rate as World War II “baby boom” children grew up; 1Apartment Construction News, July 1966, p. 33. 8Apartment Construction News, December 1971, p. 4. 9Apartment Construction News, July 1966, p. 33. 10Housing Starts, Series C20 (Bureau of the Census, April 1975), P -4 .

A rise in construction costs of about 10 percent a year11 emphasized the need for the economies of material and labor that multifamily housing could effect; 5. The relaxation of antiquated zoning laws enabled progressive developments such as the “Planned Unit Development” (PUD) to be built; 6. The advent of total community planning, especially PUD, made possible the incorporation of both single and multifamily dwellings in one community; 7. Increased geographical and job mobility made apart ment living, with its ease of moving, more desirable; 8. More women worked and had less time to spend on home management and upkeep; 9. Apartment living as a life style gained greater social acceptance. The multifamily housing industry during the past decade generally has followed traditional construction practices: Wood frame for low rise buildings, and reinforced concrete or structural steel for high rise. Modular unit construction techniques made some headway between 1969 and 1973, but they have tapered off since that time. More successful 11 Apartment Construction News, May 1974, p. 5. has been the modification of industrialized system con struction where component parts such as wall panels, bathroom modules, and floor slabs are prefabricated and then erected at the construction site. The development of new products for the apartment construction industry has been slow, but the steadily spiraling cost of lumber has resulted in greater use of concrete and metals such as steel and aluminum for framing in low rise structures. The construction industry as a whole is composed of a multiplicity of small firms. The same is true of the housing construction segment of the industry as well. In 1972, 86,749 establishments employed 460,155 workers and had receipts of more than S21.3 million.12 Of these firms, 7,965 were primarily engaged in building multifamily dwellings; they had receipts of over $6.3 million and employed over 112,000 workers. Multifamily housing construction is expected to expand in the foreseeable future and should continue to be studied for a better understanding of its growing role in the economy. 121972 Census o f Construction Industries, Preliminary Reports CC72(P)—1 and CC72(P)—2 (Bureau of the Census, January and March 1974), pp. 1—4. Chapter II. Highlights of Findings General findings Private multifamily housing construction required 50 employee-hours of onsite labor for each $1,000 expended in 1971, according to the survey. This compares with estimates from other studies of 49 employee-hours for single-family housing and 65 for public housing.13 Thus, multifamily housing construction requires about the same number of employee-hours for a given amount of expendi ture as single-family housing; public housing calls for the greatest number of employee-hours. A total of 126 employee-hours of labor was generated in all sectors of the economy for each $1,000 of construction cost for multifamily housing in 1971, as shown in table 1. (Also see charts 2 and 3.) Of this amount, 50 employeehours were expended at the construction site and another 8 employee-hours of offsite labor were expended in con tractors’ warehouses and offices,14 for a total of 58 direct construction employee-hours. In addition to he 58 employee-hours of direct labor requirements generated in the construction industry, 68 employee-hours per $1,000 of construction cost were created in industries which produce, transport, and sell materials, equipment, and supplies used in multifamily housing construction. Thus, for every hour of onsite construction work, an additional 0.2 hour of labor was spent in contractors’ warehouses and offices, and 1.4 hours in industries other than construction. Apartment construction in 1971 provided an estimated 414,000 full-time jobs for construction workers and an additional 57,000 jobs for contractors’ offsite personnel.15 Table 1.

Also, 437,000 jobs were generated in industries which provided materials used to construct multifamily units. Thus, for every onsite construction job, an additional 0.1 job was spent in contractors’ warehouses and offices and 1.1 jobs in industries other than construction.16 On average, a multifamily project took 57 weeks to complete. Actual construction of the sample projects took place in 1970 through 1972, but most were completed in 1971. Each project in the study contained an average of 157 dwelling units. These apartments averaged 979 square feet in size, cost $12,686 (excluding land) to build, and had two bedrooms. These averages generally varied according to geographic region. Requirements by occupation and type of contractor 13Labor and Material Requirements for Public Housing Con struction, Bull. 1821 (Bureau of Labor Statistics, 1974); Labor and Material Requirements for Construction o f Private Single-family Houses, Bull. 1755 (Bureau of Labor Statistics, 1972); adjusted to reflect 1971 prices and productivity. 14 Offsite construction employee-hours were estimated from the ratio of nonconstruction workers to total workers for the special trade construction industry (SIC 17), as shown in the BLS periodical Employment and Earnings, March 1971. The resulting hours were adjusted to remove that portion of administrative and clerical hours already counted as onsite. 15 These estimates are stated as full-time job equivalents since, in actual practice, more workers could be employed than indicated because of the seasonal nature of construction employment. Jobs created by the respending of wages and salaries of workers and profits of contractors (the rippling or multiplier effect) are beyond the scope of the present work. Carpenters, laborers, and helpers, the largest components of onsite labor requirements for multifamily housing, each made up over 25 percent of onsite requirements. The occupational distribution was similar to that found in public housing but quite different from that in single-family housing construction, since relatively less wood is used in multifamily than in single-family housing construction, pro portionately fewer carpenters were employed; since much larger amounts of heavier materials must be moved onto 16 Due to differing assumptions for the number of employeehours per employee-year in construction and other industries, employee-hour ratios do not apply to employee-year estimates. To calculate employment, 1,800 hours a year were used for con struction and 2,000 for all other industries. Chart 2. Employee-Hour Requirements per $1 ,000 o f Contract Cost in Apartment Construction, by Industry, 1971 Construction Manufacturing Wholesale trades, transportation and services Mining and all other Chart 3. Employee-Hour Requirements Per 100 Square Feet o f Apartment Construction, by Industry, 1971 and within the site, relatively more laborers were required. In descending order, other important occupations for multi family housing construction were plumbers, electricians, superintendents and blue-collar supervisors, bricklayers, painters, cement finishers and operating engineers. The general contractor provided a little over 20 percent of onsite employee-hours, followed by carpentry con tractors (about 13 percent), normally second in onsite hours in building construction. Next were concrete work, plumbing, and masonry contractors, each with about 9 to 10 percent of the onsite work. Since wallboard virtually has replaced plaster for interior walls, wallboard contractors had about 8 percent of the onsite work compared with 2 percent for plasterers, and four times the value of plastering contractors in contract costs. Distribution of costs The general contractor was paid about one-third of all contract costs, considerably more than his contribution in employee-hours. This proportion reflects the increasing trend for general contractors to subcontract onsite work and concentrate on coordinating, financing, and purchasing. Other important cost components by operation were carpentry; plumbing; concrete; heating, ventilating, and air-conditioning; electrical; wallboard; and masonry. Of overall costs, onsite wages and salaries constituted almost 30 percent, with carpenters and laborers representing nearly one-half of this amount (chart 4). Skilled trades made up about two-thirds of total onsite direct labor costs, similar to their proportion in private single-family and public housing construction. Materials and supplies constituted over two-fifths of construction costs. Three major groups made up over one-half of the cost of all materials used in multifamily housing construction. Stone, clay, glass, and concrete products represented over one-fifth of these costs, or $105 per $1,000 of costs. Most important within this grouping were ready-mix concrete, and wallboard. Lumber and wood products, except furniture and fixtures, were the next most expensive materials—$89 per $1,000 of costs. The materials representing the largest costs in this group were rough and dressed lumber, millwork, and plywood. Fabricated metal products, the third most important group, constituted $74 per $1,000 of costs. Within this group, the important products were metal doors and windows, reinforcing bars, sheet metal, plumbing products, and heating equipment. Except for construction equipment (about 3 percent of contract costs or about $31 per $1,000), the remaining costs, almost 25 percent of the total, were not collected for the survey but consisted of items such as supplementary wage benefits paid by contractors, construction financing costs, offsite work in offices and warehouses, other overhead expenses, and profit. Regional differences Differences in construction characteristics reflect re gional conditions under which buddings are erected.17 For exam ple, in three regions, the “two-to-three-story” gardentype apartment building was the major type but in the Northeast the “four and over” group predominated (table 2). Furthermore, reinforced concrete instead of wood was used most often in the Northeast for framing buildings. Probably the high population density and cost of land in the Northeast led to taller buildings with reinforced concrete and, in some cases, structural steel frames. Also, brick exterior siding was used for insulation and weathering in every region except the West, where stucco pre dominated due to the milder climate. 17 The study provided data for the United States and four broad geographic regions. States in each region included: N ortheastConnecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, and Vermont; North Central-Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Mis souri, Nebraska, North Dakota, Ohio, South Dakota, and Wisconsin; S o u th -Alabama, Arkansas, Delaware, District o f Columbia, Florida, Georgia, Kentucky, Louisiana, Maryland, Mississippi, North Car olina, Oklahoma, South Carolina, Tennessee, Texas, Virginia, and West Virginia; West- Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming.

These higher costs were the result of several factors. The buildings in this region tended to have more stories and generally contained elevators. Also, most of them had frames made of reinforced concrete as opposed to wood framing, used in the other regions. In addition, average hourly earnings of onsite workers were higher than in all the other regions except the North Central, and the proportion of contract costs allocated to wages was the highest. However, when measured by square footage, apartments in the Northeast were the smallest. Average hourly earnings also varied according to region. The U.S. average of $5.60 reflected the range from $4.57 in the South to $6.32 in the North Central region. Wages as a percent of contract costs varied from about 25 percent in the West to almost 31 percent in the Northeast. Lower wage rates in the South kept total wage costs low on projects in this area, i.e., about 27 percent of contract costs. On the other hand, in the West, as shown in table 2, only about 25 percent of contract costs went for wages, despite the fact that average hourly earnings ($6.22) were significantly higher than in the South ($4.57). A similar divergence was found in the Northeast. Although average hourly rates in the Northeast were lower than those in the North Central region, total wage costs as a percent of contract costs were higher. This anomaly in these regions could be due to differing rates of productivity, differences in relative costs of materials, and other factors. Chapter III. Labor Requirements and Characteristics single-family housing, public housing, and college housing. However, a significantly higher proportion of onsite em ployee-hours in private multifamily construction was con tributed by workers in nonproduction occupations, as shown by the following tabulation: Onsite Employee-hours by occupation. Data for the United States as a whole indicate that, of onsite employee-hours in apartment construction, 66 percent were worked by skilled tradesworkers, 28 percent by semiskilled and unskilled workers, and 6 percent by nonproduction employees such as supervisors, engineers, and clerks (table 3). For skilled trades and semiskilled and unskilled workers, the proportion of employee-hours was essentially the same as that found in other types of residential construction, i.e., Nonproduction employee-hours as percent o f all onsite employee-hours Private multifamily housing..........

Carpenters, the major skilled craft, accounted for 38 percent of the employee-hours of all skilled workers. They were followed, in descending order, by plumbers, elec tricians, bricklayers, and painters. The ranking of skilled trades varied within the four broad geographical regions. Carpenters and plumbers ranked first and second respectively in all regions. However, the relative importance of the other trades changed from region to region. Bricklayers were in third position in the Northeast and South, fourth in the North Central region, and below the first five in the West. Cement finishers were fourth in the Northeast and fifth in the West; they ranked below fifth in the South and North Central regions. Electricians ranked third in all regions except the South where they were fifth. Painters occupied fourth place in the South and West but were below the top five in the other regions. Table 4. 1971 In square footage, 64.8 employee-hours were required for each 100 square feet of space constructed (table 4). Employee-hours per 100 square feet ranged from about 48 in the West to about 91 in the Northeast. Employee-hour requirements by occupation were the same, proportion ately, for 100 square feet as for $1,000 of construction. Apprentices made up about 8 percent of all skilled workers, as shown in the tabulation below. This figure ranged from about 5 percent in the South to nearly 12 percent in the West. The occupations which had the largest relative numbers of apprentices were plumbers and pipe fitters, electricians, machinists, and soft-floor layers.

National data show that general contractors used 21.7 percent and carpentry contractors 12.8 percent of onsite construction employeehours (table 5). They were followed, in descending order, by contractors of plumbing, 9.0 percent; masonry, 8.8 percent; and wallboard, 7.9 percent. The rankings of the various contractors varied within the regions. The general contractor ranked first and the carpentry contractor second in all regions except the Northeast where the general contractor occupied third place with 11.8 percent of the onsite employee-hours. In that area concrete work and masonry, with 23.2 and 12.1 percent, respectively, of the employee-hours, were in first and second place, and wallboard contractors, with 8.3 percent, and plumbers, with 8.0 percent of onsite em ployee-hours, ranked fourth and fifth. The variation in contractor rankings among the regions is illustrated by the list below showing the contractors who ranked third in each region: Percent o f employee-hours Type o f contractor 11.8 General Masonry Plumbing Plumbing 11.1 10.7 13.4 Employee-hour requirements by building characteristics. Data on employee-hours by various building features indicate that in most cases employee-hour requirements were lowest in buildings using the most common materials and features. For example, wood was the most common framing material used, and projects with this type of framing had the lowest employee-hour requirements, about 46 employee-hours per $ 1,000 of construction costs (table 6). Similarly, poured concrete foundations, dry wall interior walls, concrete floor base, carpet floor covering, and wood/plywood roof base followed the same trend. Further more, the pattern was the same for items other than materials. That is, sample projects with individual apart ment heating occurred more frequently and required fewer employee-hours than individual building or central project heating. This finding was equally true of buildings with forced air heating, gas fuel, individual air-conditioning, of two to three stories, and buildings without elevators, incinerators, or compactors. Generally, the most widely used materials and building practices are popular because they are the most efficient or least expensive. However, although brick was used most widely for exterior walls, projects with stucco outside walls had the lowest employee-hour requirements. Stucco, a concrete siding material, is used widely in the Southwest and southern California. Table 5.

Despite smaller average units in the Northeast, construc tion costs per unit were the highest because onsite employee-hours per 100 square feet were the highest (table 6), onsite average hourly earnings were second highest (table 7), and, because of the taller buildings of that region, over two-thirds of the projects had elevators. There was not a perfect correlation between the propor tion of total construction cost that was accounted for by wages, and average onsite hourly earnings, degree of unionization, or onsite labor hours per $1,000 of construc tion contract. However, there tended to be a close relationship among these variables, on a regional basis. The tabulation below provides some indication of these inter relations: Most projects surveyed had poured concrete founda tions, wood frames, brick exterior walls, and were two to three' stories high with two bedrooms per unit and no elevators. This pattern was largely the same in all regions except the Northeast. In that region, the dominant type of frame was reinforced concrete and most projects were four stories and over with elevators. The distinctive characteristics of projects in the North east region were reflected in the distribution of onsite employee-hours by type of contractor. For example, since a large proportion of these projects had reinforced concrete frames, concrete work contractors had the greatest propor tion of total onsite employee-hours. Of course, the pre dominance of reinforced concrete frames was a direct result of the generally taller buildings in the Northeast. Union contracts Onsite as a percent of employee-h ours per $1,000 total contracts Wages and earnings by building characteristics. Of the surveyed housing, the average project had 157 dwelling units with 979 square feet per dwelling unit. Each unit cost $12,686. In the Northeast, building characteristics differed sharply from those of the other regions. Projects in the Northeast had the largest number of dwelling units, 240, compared with the South, 149; the North Central region, 163; and the West, 135.

The South shows the classic relationship among the three series, e.g., the smallest amount of unionization, the greatest amount of onsite employee-hours per $1,000, and the lowest average hourly earnings. On the other hand, in the West the interaction of these three variables is somewhat more subtle. The West led in the degree of unionization, which would tend to raise the hourly wage rate. The reaction to this apparently was a more efficient use of labor; the West had the lowest number of onsite employee-hours per $1,000 and the second lowest onsite average hourly earnings. Lower hourly earnings are largely the result of a smaller percentage of total onsite labor hours being paid at overtime rates. Similar generaliza tions can be made about the other two regions. Obviously, there are extraneous factors which this survey was not able to measure. Cost per square fo o t by building characteristics. Cost per square foot by characteristics of buildings, shown in table 8, exhibited the same trend as employee-hour requirements. That is, the more common a given characteristic, the more likely it was to have the lowest cost per square foot. Although this pattern was true less frequently than for employee-hours, nevertheless it was predominant in all regions. Wood frame buildings, for example, cost the least per square foot and wood was the most frequently used framing material for apartment construction. Exceptions were in foundations, exterior walls, floor base, and roof covering. Offsite Offsite employee-hours represent the builder’s admini strative office and warehousing activities, and the labor to produce and distribute the materials, supplies, and equip ment required at the construction site. Major categories involved are: (1) Offsite construction, (2) manufacturing, (3) wholesale trade, transportation, and services, and (4) other industries either directly or indirectly involved in the production and distribution process. For every hour of work performed at the construction site, an additional 1.5 employee-hours of effort were required to produce these materials, supplies, and services (including offsite construction). These expenditures amounted to 76 employee-hours for each $1,000 of construction.18 Builders' offsite employee-hours. Eight employee-hours per $1,000 of construction were expended in this category, which includes contractors’ administrative, coordinating, estimating, scheduling, engineering, maintenance, and ware housing activities. Construction offsite hours, a relatively small portion of employee-hour requirements, constituted 61 18 Retail trade is excluded from this estimate because purchased transactions for materials are assumed to be made at the wholesale level only. Some retail transactions are made, but the extent o f such purchases in construction is not known. percent of the total. This is inherent in an industry where an average of 31 subcontracts is involved in each project. The general contractor often limits his major responsibili ties to overall coordination, scheduling, control, and super vision of construction. Manufacturing employee-hours. The manufacturing sector was by far the largest and most important contributor of offsite employee-hours because of the materials, supplies, and equipment required for construction. Involved were 59 major industrial producer groups, requiring 43 employeehours per $1,000 of construction or 63 percent of all offsite employee-hours, excluding offsite builder activities. Four major groups made up 50 percent of all manufac turing employee-hours: (1) Logging, sawmills, and planing mills; (2) millwork and plywood; (3) cement, clay, and concrete products; and (4) fabricated structural metal. Wholesale trade, transportation, and service employee-hours. Fifteen employee-hours per $1,000 of construction were re quired to produce the items from this sector of the economy. Wholesale trade and transportation contributed 80 percent of this amount. Mining and other industries employee-hours. This group in cluded agriculture, maintenance, construction, communica tions, utilities, finance, insurance, real estate, and govern ment enterprises. Ten employee-hours per $1,000 of con struction were generated in these sectors. This initial study of multifamily housing construction did not permit comparison of changes in cost relationships from previous years in this segment of residential construc tion. However, comparisons can be made with studies of other types of residential construction. Analysis of the bill of materials for a study of public housing construction for 1968, for example, indicated the same pattern of expendi tures for each major materials group. The stone, clay, glass, and concrete products group made up over 25 percent of the cost of materials and equipment; lumber and wood products represented another 14 percent. These two cate gories of construction, i.e., multifamily and public housing, were similar in type of construction but building char acteristics varied in many respects. In a 1969 survey of single-family housing construction, the three most important categories of material expend itures, making up about 72 percent of total materials and equipment costs, were lumber and wood products; stone, clay, glass, and concrete products; and fabricated metal products. Disbursements for these three types of expendi tures in multifamily housing construction were con siderably more and their relative importance was quite different. For single-family housing, lumber and wood products required the greatest expenditure per $1,000 of construction and constituted 37 percent of all materials and equipment costs. Stone, clay, glass, and concrete products, which were second, made up 21 percent of the cost. These results were expected because of differences in the type of construction and building characteristics. Table 8.

Chapter IV. Distribution of Costs and Wages Relative cost shares Onsite wages made up 28 percent of the total construc tion cost, as shown in the distribution of construction contract value below: United States North east South North Central West 100.0 100.0 (percent) Total costs ......... . Onsite wages and salaries ....................... Materials and supplies . Equipment ................... Overhead and profit . . 100.0 27.9 44.2 3.0 24.8 100.0 30.8 37.6 2.5 29.1 100.0 28.5 46.8 2.6 22.1 27.3 46.5 3.5 22.7 25.2 43.7 3.4 27.7 The largest share of these costs, 44 percent, went for materials and supplies. Equipment used to construct the projects made up another 3 percent of cost. The remaining 25 percent covered builders’ and contractors’ overhead costs19 and profit. Contractor costs The distribution of construction contract value by contractor as shown in table 9 looks quite different from the employee-hour distribution discussed earlier. General contractors, for example, made up just under 32 percent of the total contract value but only about 22 percent of onsite employee-hours for the United States as a whole. On the other hand, carpenters provided nearly 13 percent of the employee-hours but received less than 10 percent of the contract value. This discrepancy is explained in part by the significant amount of overhead which the general con tractor assumes on any project. Other contractors, ac counting for a significant but decreasing proportion of contract value, were plumbing; concrete; heating, vent ilating, and air-conditioning; electrical; wallboard; and masonry. All the regions displayed the same general contract value pattern. However, a different mix of buildings in the four regions resulted in a considerable range in the contract value accounted for by some types of contractors. For example, concrete work received about 9 percent of the contract value for the United States as a whole, but by1 19Overhead costs include salaries of offsite workers, supplemental benefits, interest expense, other overhead, and miscellaneous ex penses.

The proportion of contract value going for carpentry did not have as wide a range but was considerably higher in the North Central region and the West where wood was used more in apartment buildings. The masonry contractors’ share dropped off considerably in the West where wood is used primarily for framing and stucco is used for building exteriors. The general contractor provided the major portion of the total cost for materials, equipment, and supplies; onsite labor; and administrative costs in all regions. Only in the Northeast was the concrete contractor the leading sub contractor in value of contract. This was a direct result of the structural characteristics of the nine sample projects in that region. For example, seven projects had poured concrete foundations, three had reinforced concrete frames, five had a concrete floor base, and four had concrete roof bases. The carpentry contractor was the leading sub contractor in the other regions. Table 9 provides a percent distribution of contract value by type of contractor, nationally and for the four regions. Gross earnings by occupation The percent distribution of gross wages by occupation (table 10) presents a different pattern from the distribution of employee-hours shown in table 4. Although skilled trades provided about 66 percent of U.S. total onsite hours, Table 10.

United States North east South 100.0 100.0 100.0 North West Central 100.0 their proportion of earnings was higher, almost 72 percent. Conversely, laborers and other semiskilled and unskilled occupations contributed 28 percent of onsite employeehours; but their proportion of total pay was only 21 percent. Although carpenters ranked second after laborers and helpers in employee-hours, they were well above in gross earnings. These two groups received 46 percent of all wages paid in apartment construction. In descending order of total wages received, other important occupations were plumbers and pipefitters, superintendents and blue-collar supervisors, electricians, bricklayers, painters, cement fin ishers, and operating engineers. All regions tended to follow a similar pattern. Carpenters receive the largest proportion of any occupation in each region except the South. Onsite wages received by car penters ranged from just under 22 percent in the Northeast to almost 34 percent in the West because of the greater amount of wood used in that region. The proportion of wages paid to laborers and helpers ranged from about 13 percent of the total in the West to over 25 percent in the South. 100.0 Wages by occupation 7.7 7.4 7.7 7.2 8.9 .4 1.1 .3 .1 .3 7.2 6.0 7.2 7.0 8.5 .2 .3 .2 .1 .1 71.6 5.5 27.0 3.6 71.2 6.6 6.8 75.9 5.4 30.1 3.1 7.9 76.6 6.8 21.8 65.3 7.5 23.8 3.0 5.5 .4 .4 .9 .5 .3 .4 .2 .1 .3 .4 .6 .8 .5 .8 .4 .7 1.0 .8 .5 .7 1.4 4.3 .6 .6 1.2 2.1 .3 3.0 5.3 .8 .1 3.1 4.1 1.3 10.6 .8 2.2 5.2 3.2 1.7 1.1 3.6 3.0 .4 .8 33.9 3.4 6.8 .2 1.4 3.5 4.5 11.1 .7 3.7 1.3 2.8 .1 1.0 .7 .5 27.0 2.3 16.9 1.9 14.5 25.2 .7 .4 15.4 .7 .3 12.8 .5 .7 .5 8.4 .7 1.9 .7 .8 .6 .8 1.4 20.7 .8 .8 21.4 19.0 .7 19.8 .7 .2 .1 .7 .8 ____{L A verage hourly earnings from study Union wage rate All occupations................... $5.56 $6.18 Glaziers...........................................

The following tabulation shows the average hourly earnings developed by the study and the union wage rates for the four broad regions: 2.2 11.6 12.3 .5 .4 .4 Straight-time average hourly rates (unweighted) in this study generally were lower than average union hourly wage rates in the building trades as of July 1, 1970.20 Excep tions are shown in the following tabulation: A verage hourly earnings from study Union wage rate United States ..................... $5.60 $6.18 Northeast ......................................

Only 25.1 percent of the contracts in the 20 See Union Wages and Hours: Building Trades, July 1, 1970, Bull. 1709 (Bureau of Labor Statistics, 1971). study for the South were with unionized contractors compared with 90.8 percent for the West. The union wage rate exceeds the study’s average earnings rate in all regions except the West. The higher earnings rate in the West is largely a reflection of the fact that a higher percentage of the onsite employee-hours were provided by skilled trades, i.e., 73.8 percent compared to the national average of 66.1 percent. The North Central region also employed a high proportion of skilled workers, 72.7 percent, and hourly earnings almost equaled the union rate. Other factors that may account for some of the disparity between these two series are (a) the inclusion of overtime in the study’s data (b) the exclusion of Alaska from the area covered by the survey. Wage share Onsite wages as a percent of total cost for the projects studied ranged from under 20.0 to over 40.1 percent. Although distributed fairly evenly over the range up to 32.5 percent, the proportion of projects dropped significantly for wage costs above this level, as shown in the following tabulation. The median class was 25.1 to 27.5 percent of contract cost.

The West ranks first in both tabulations; that is, it had the lowest expenditure of employee-hours per $1,000 of contract cost and the lowest proportion of the cost allotted for onsite wages. However, the position of the South in the two distributions, at first, appears contradictory. That is, the South had the highest expenditure of employee-hours per $1,000 of total contract cost and the second lowest expenditure for onsite wages as a percent of total cost. This situation is the result of the South having the lowest average hourly earnings, $4.57. Materials, supplies, and equipment. Materials, supplies, and equipment costs for multifamily housing construction amounted to $476 per $1,000 of construction costs, or $617 per 100 square feet (table 11). Of this amount, 94 percent was spent for materials and supplies and the balance was allocated to the rental value or equivalent of equipment required during construction. The stone, clay, glass, and concrete products category' had the largest disbursements for materials, with $105 expended per $1,000 of construction costs or 22 percent of all materials and equipment costs. Lumber and wood products, except furniture, were $89 per $1,000 of construction, or 19 percent of materials and equipment costs. The fabricated metal products group, except ord nance and transportation equipment, was next most im portant at $74 or 16 percent. These three major categories constituted 57 percent of all purchased materials, supplies, and equipment costs. Other individual categories of m ate rials ranked considerably below these figures in relative importance. For convenience, construction machinery and equip ment were included in the materials table as a separate category. Costs for construction equipment were based on rental or equivalent value of machinery or equipment at the construction site, exclusive of equipment operators. Ex penditures amounted to $31 per $1,000 or slightly over 6 percent of all materials and equipment costs. Table 11.

Comparison With Other Surveys Employee-hour requirements for multifamily housing construction were the lowest of any building construction sector studied in the BLS labor requirements series (table 12).21 However, it is possible that requirements for single-family housing might have been the same as for apartment construction, or slightly lower, if the studies had been conducted in the same year. In occupational requirements, multifamily housing did not closely match any of the other three residential studies in the BLS series—college housing, public housing, and single-family housing (table 13). Occupational requirements for multifamily housing were highest for administrative and supervisory workers and lowest for bricklayers, iron workers, plasterers and lathers, and laborers, helpers, and tenders. Comparison of the cost figures in table 14 for multi family housing with those for the other two recent 21 In comparing the multifamily housing construction survey with other surveys of construction labor requirements, it must be kept in mind that the studies cover different time periods. Furthermore, comparisons cannot reasonably be made with heavy construction (i.e. highways, sewer works, and civil works) which is entirely different from residential and other building construction in labor and material requirements. Table 12. 1958-73 residential surveys indicates that the proportion of onsite wages for multifamily housing, 27.9 percent, was higher than for single-family housing, 20.4 percent, but that public housing was the highest, at 32.4 percent. The ratio of materials for multifamily housing (44.2 percent) was very close to the ratios for the other two studies. On the other hand, among these three residential surveys, cost of equipment was the highest for multifamily housing, which indicates the more capital-intensive nature of taller build ings in that type of construction. Material requirements for multifamily housing more closely resembled those for public housing than for other types of residential construction studied (table 15). Al though multifamily housing required a larger proportion of lumber and a smaller proportion of metal products and stone, clay, glass, and concrete products than public housing, these three groups of materials made up the majority of materials in both types of construction. These three groups constituted 58 percent of total materials, equipment, and supplies for multifamily housing and over 62 percent for public housing. The proportion of con struction equipment was considerably higher for multi family housing than for other residential construction because of the heavy equipment required to build the generally higher multifamily structures.

Survey Scope and Methods The study was designed primarily to develop estimates of employee-hour requirements for the construction of private multifamily housing in structures of five units or more in Standard Metropolitan Statistical Areas. Characteristics of universe and selection of sample The sample frame was constructed by analyzing the distribution of building permits issued during calendar year 1969, as shown in the Bureau of the Census, Construction Reports, C40-69-13, “Housing Authorized by Building Permits and Public Contracts, 1969.” A probability sample of metropolitan areas was drawn to represent all privately owned multifamily housing in structures of five units or more located in metropolitan areas, where building permits were issued during 1969 for 500 units or more of this type. The following 22 Standard Metropolitan Statistical Areas were selected Atlanta Baltimore Boston Chicago Cincinnati Dallas Denver Detroit Houston Kansas City Los Angeles Memphis Miami Minneapolis New Orleans New York Oklahoma City Philadelphia Phoenix San Diego San Francisco Washington It was not feasible for the Bureau of the Census to provide a list of all completed projects in the survey universe. However, a significant portion of these projects were financed under the auspices of the Federal Housing Administration (FHA). FHA-insured starts of buildings with five units or more in metropolitan areas during calendar years 1969, 1970, and 1971 were estimated as 14, 35, and 27 percent respectively of the total starts in that class. Accordingly, the sample was drawn from FHA reports to represent the entire survey universe, which includes non-FHA starts. A sample of 89 projects was selected from FHA reports on projects completed between July 1, 1970, and August 1, 1971, in the areas previously listed. (After completion of the survey it was learned that most construction took place in 1971.) The survey excluded projects meeting any of the following criteria: 1. Ten percent or more of available footage is for commercial use. 2. Ten percent or more of available footage is of modular construction. 3. Ten percent or more of available footage is for townhouses. A townhouse is defined as a single family house with common walls to adjacent buildings and independent utility connections (sewer, water, gas, electricity). 4. The entire project is a condominium or cooperative development. 5. The entire project is special-purpose housing such as senior citizens’ housing, which has unique archi tectural features. Data collection procedures Three major stages were employed to fulfill the objective of reliable data for each project in the study: (1) Pretest and training, (2) Federal Housing Administration (FHA) area office visits, and (3) visits to project sites and contractors. Pretest and training. Education and orientation were accomplished in two ways. First, experienced data collec tors from three regional offices assembled in Washington, D. C., to discuss the survey and prepare for the pretest. The Washington staff explained the purpose of the complex study and proposed collection schedules. Informal dis cussion was conducted to clarify specific points, and agreement was reached on the data required to meet the objectives. Each regional representative was then assigned two projects for pretest. The representatives were to visit the FHA area office, general contractor, and subcontractors for each project. When this assignment was completed, all data were forwarded to Washington with a critique and recommendations for improvements and modifications to the survey approach. The Washington staff revised and improved final schedules and field instructions. Next, representatives from all eight BLS regional offices met in Washington, D.C., for a training session. All facets of the program were explained in detail with the use of training aids, collection instructions, and schedules for data collection. Findings of the pretest survey were presented and potential problem areas were discussed. Regional coordinators generally transmitted this information to data collectors at a regional conference. Federal Housing Administration area office visits. During the survey planning stage, the BLS requested that the FHA send a letter describing the survey to all FHA area offices to solicit their cooperation when a BLS representative would visit. This approach assured entree to the area offices with FHA endorsements for the survey. The BLS data collectors had three missions to perform when visiting the area office; (1) Obtain project payrolls, (2) obtain building characteristics, and (3) obtain listings of all contractors involved in the project construction. The data collectors arranged to have payroll data of the general contractor and subcontractors forwarded to the BLS regional office on loan. (Contractors are required to keep these records for 3 years to comply with the Davis-Bacon Act.) In some cases, the payrolls had been placed in a Federal storage depository and authorization had to be obtained to secure them. In other cases, copies of the original payrolls were made and forwarded to the BLS regional office. Next, the BLS data collectors obtained the name, address, contract value, and type of contract for all general and prime contractors and subcontractors on the sample project. Missing payrolls were identified so that the contractor could later furnish supplemental information. Visits to project sites and contractors. After completing their research at the FHA area office, data collectors visited the construction site to become as familiar as possible with the structural characteristics of the project before visiting the general contractor. If the general contractor should refuse to cooperate, the project would have to be dropped and another one substituted. The substitution of sample projects is time consuming and costly and, in addition, could bias the survey results. Therefore, every effort was made to enlist the cooperation of the general contractor by explaining the nature of the survey and the reasons for conducting it. Of the approximately 2,800 contractors who were interviewed in the sample of 89 projects, only a small number refused to cooperate or could not be located. If the contractor agreed, he was asked to verify the final contract value, including change orders, and the list of subcontractors and their current addresses. Additional payroll data were obtained for onsite workers who were not covered by the Davis-Bacon Act, such as the super intendent, technical personnel, and watchmen. Finally the data collectors recorded the type of each material, its purchase cost, and the name and fair rental value or equivalent of any equipment used on the job. Each of the subcontractors also was contacted to obtain similar data. After all the data for a sample project were collected, they were checked for completeness and internal con sistency by the regional office and forwarded to Washing ton, D.C., for final analysis, editing, and coding for computer processing. Data collected for the private multifamily construction survey were very complex and required experienced per sonnel for processing. Procedures used to develop employee-hour estimates Onsite and offsite employee-hour estimates were com bined to obtain estimates of total employee-hour require ments for private multifamily housing. Onsite (direct) employee-hours, as explained in the previous section, were obtained from payrolls submitted by the contractors to the FHA. Offsite (indirect) employeehour requirements, representing the hours to produce, transport, and sell the materials, supplies and equipment used in construction, were developed by use of the 1963 Interindustry Study of the Bureau of Economic Analysis (BEA) of the U.S. Department of Commerce. The basic data on materials, supplies, and equipment were collected by the BLS field representatives from each prime con tractor and his subcontractors (or estimated in a relatively small number of cases). The materials listings thus obtained were categorized according to the 4-digit industry classification of the Standard Industrial Classification Manual (1967 edition, Office of Management and Budget). For each product group, the average amount required for $1,000 of construc tion cost was calculated. This bill of materials was deflated to the 1963 price level by application of the appropriate wholesale price indexes. The resulting deflated value for each group was reduced by a ratio representing the difference between valuation by the purchaser and valua tion by the producer. (This ratio was based on data provided by BEA.) The differences between purchaser and producer valuation were allocated to trade and transpor tation sectors. The deflated values were matched to the sector coefficients in the 1963 interindustry study of BEA. For each group of materials, the interindustry study provided information on the amount of products required from each of the 367 industry sectors. The product data were converted to employee-hours by use of output per employee-hour ratios for each industry. While processing the data, the Economic Growth Division of BLS adjusted for price and productivity changes from the base year of the tables (1963) to the study year. The results were the average total (indirect) employee-hours per $1,000 of contract cost required to produce, transport, and sell the materials used to construct the projects covered by this survey. These employee-hours, plus the builders’ offsite employ ment, were combined with direct or onsite employee-hours to determine total employee-hours within the definition of the study. Offsite employment of each construction con tractor was not obtained directly from the contractors since it would be difficult to allocate a portion of total offsite employment to a particular project. Instead, an estimate for these employee-hours was developed by applying the ratio of construction workers to all employees in the special trade contractors industry for 1971, as reported in Employ ment and Earnings, United States, 1909-72 (BLS Bulletin 1812—9) to the onsite employee-hours collected for this study. An additional measure of employee-hours expended in construction, i.e., employee-hours per 100 square feet of construction, was developed by applying the cost per 100 square feet of construction to employee-hours per $1,000 of construction contract cost.
