June CPIP Data Shows Construction Spending at Record High

Written by Peter Wright

Construction is on a roll with expenditures in June at an all-time high, according to Steel Market Update’s latest analysis of Commerce Department data.

In the Aug. 1 data release, which reported expenditures through June, the growth of total construction on a rolling 12-month basis year over year increased from 2.1 percent in January to 2.6 percent in June. On a rolling three-month basis year over year, the situation is much better with growth improving every month from December through June when it reached 4.9 percent. Construction expenditures data is developed by the Department of Commerce and is referred to as construction put in place (CPIP). Since construction is extremely seasonal, the growth or contraction we report in this analysis has had seasonality removed by providing only year-over-year comparisons.

At SMU, we analyze the CPIP data with the intent to provide a clear description of activity that accounts for about 45 percent of total U.S. steel consumption. See the end of this report for more detail on how we perform this analysis and structure the data. In particular, note that we present non-seasonally adjusted numbers and we don’t include expenditures for residential improvements. Our rationale is that construction is highly seasonal and our businesses function in a seasonal world, and home improvements don’t consume much steel. For these reasons, our results may not align with other sources. 

Total Construction

Total construction expanded by 4.9 percent in three months through June and by 2.6 percent in 12 months through June, both year over year. Since the three-month growth rate is higher than the 12-month rate, we conclude that momentum is positive. June construction expenditures totaled $97.8 billion, which breaks down to $69.5 billion of private work, $26.5 billion of state and locally funded (S&L) work, and $1.8 billion of federally funded work (Table 1). Growth trend columns in all four tables in this report show momentum.

Figure 1 shows total construction expenditures on a rolling 12-month basis as the blue line and the rolling three-month year-over-year growth rate as the brown bars. Total construction is at an all-time high.

Figures 1, 2, 6, 7 and 9 in this analysis have the same format, the result of which is to smooth out variation and eliminate seasonality. We consider four sectors within total construction. These are nonresidential, residential, infrastructure and other. The latter is a catchall and includes industrial, utilities and power. Of these four sectors, only residential buildings had negative momentum in the June data, which was the same as the previous five months’ results.

The pre-recession peak of total construction on a rolling 12-month basis was $1.028 trillion through November 2006. The low point was $665.1 billion in the 12 months through April 2011. In 12 months through June 2018, construction expenditures totaled $1.072 trillion. (This number excludes residential improvements; see explanation below.)

Private Construction

Table 2 shows the breakdown of private expenditures into residential and nonresidential and subsectors of both. The growth rate of private construction in three months through June 2018 was 4.3 percent, up from 1.9 percent in the three months through last November as shown by the brown bars in Figure 2. Private construction has finally reached the pre-recession rate of expenditures.

Within private non-residential buildings, momentum was mixed with four positive sectors, four negative and one unchanged.

Excluding property improvements, our report shows that single-family residential grew by 7.7 percent in three months through June with negative momentum and multifamily residential grew by 1.6 percent with positive momentum. Homebuilder sentiment is high, but has been declining since last December. In our view, the 2018 tax legislation and rising interest rates put single-family home construction in jeopardy. The Census Bureau reports on construction starts in its housing analysis. In the starts data, the whole project is entered into the database when ground is broken. Construction put in place is based on spending as it occurs; the value of a project is spread out from the project’s start to its completion. Single-family starts grew by 8.7 percent in the three months through June year over year, which was very close to the growth rate of CPIP. Multifamily starts grew by 5.7 percent on the same basis. Figure 3 shows the growth of both housing sectors since January 2005 and Figure 4 shows the ratio of single-family to multifamily starts. The proportion of single-family has been gradually increasing since June 2015 when the ratio was 1.66 in favor of single units to 2.59 in June 2018. Figure 5 shows total housing starts in four regions with the South being the strongest and the North East the weakest.

State and Local Construction

S&L work expanded by 7.0 percent in the rolling three months through June year over year with positive momentum. January through June were the first months with positive growth since 2016 (Table 3). The improvement was driven by nonresidential buildings and infrastructure, both of which are included in the S&L data. Table 3 shows that S&L nonresidential buildings expanded by 4.7 percent in three months through June. Educational is by far the largest subsector of S&L nonresidential buildings at $6.7 billion in June and experienced 0.2 percent negative growth on a rolling three-months basis with negative momentum. Figure 6 shows the history of total S&L expenditures and that a full recovery to the pre-recession level of expenditures probably won’t be achieved until sometime in the next decade.

Drilling down into the private and S&L sectors as presented in Tables 2 and 3 shows which project types should be targeted for steel sales and which should be avoided. There are also regional differences to be considered, data for which is not available from the Commerce Department.


Infrastructure expenditures peaked in early 2016 and declined through 2017 before beginning a recovery in 2018. June had an 8.3 percent growth rate. Highways and streets including pavement and bridges account for about two-thirds of total infrastructure expenditures. Highway pavement is the main subcomponent of highways and streets and had a 5.4 percent growth in three months through June. Bridge expenditures have expanded every month this year, improving to a 10.4 percent growth rate in June (Table 4). This was the best growth rate for bridge construction since October 2015.

Figure 7 shows the history of infrastructure expenditures and the year-over-year growth rate.

Total Building Construction Including Residential

Figure 8 compares year-to-date expenditures for building construction for 2017 and 2018. Single-family residential is dominant and in the 12 months of 2017 totaled $264.5 billion, up from $242.5 billion in 2016. It seems likely that the 2018 tax bill, by its reduction in the deductibility of mortgage interest and local taxes, will negatively affect single-family home construction.

Figure 9 shows total expenditures and growth of nonresidential building construction. Growth slowed in January through July last year, went negative in August through October then became positive in November through June 2018.

Explanation: Each month, the Commerce Department issues its construction put in place data, usually on the first working day covering activity one month and one day earlier. Construction put in place is based on spending work as it occurs, estimated for a given month from a sample of projects. In effect, the value of a project is spread out from the project’s start to its completion. This is different from the starts data published by the Census Bureau for residential construction, by Dodge Data & Analytics and Reed Construction for nonresidential, and Industrial Information Resources for industrial construction. In the case of starts data, the whole project is entered to the database when ground is broken. The result is that the starts data can be very spiky, which is not the case with CPIP.

The official CPIP press release gives no appreciation of trends on a historical basis and merely compares the current month with the previous one on a seasonally adjusted basis. The background data is provided as both seasonally adjusted and non-adjusted. The detail is hidden in the published tables, which SMU tracks and dissects to provide a long-term perspective. Our intent is to provide a route map for those subscribers who are dependent on this industry to “follow the money.” This is a very broad and complex subject, therefore to make this monthly write-up more comprehensible, we are keeping the information format as consistent as possible. In our opinion, the absolute value of the dollar expenditures presented are of little interest. What we are after is the magnitude of growth or contraction of the various sectors. In the SMU analysis, we consider only the non-seasonally adjusted data. We eliminate seasonal effects by comparing rolling three-month expenditures year over year. CPIP data also includes the category of residential improvements, which we have removed from our analysis because such expenditures are minor consumers of steel.

In the four tables included in this analysis, we present the non-seasonally adjusted expenditures for the most recent data release. Growth rates presented are all year over year and are the rate for the single month’s result, the rolling three months and the rolling 12 months. We ignore the single month year-over-year result in our write-ups because these numbers are preliminary and can contain too much noise. The growth trend columns indicate momentum. If the rolling three-month growth rate is stronger than the rolling 12 months, we define that as positive momentum, and vice versa. In the text, when we refer to growth rate, we are describing the rolling three-month year-over-year rate. In Figures 1 through 4 and 6, the blue lines represent the rolling 12-month expenditures and the brown bars represent the rolling three-month year-over-year growth rates.
