Pandemic #14 – Impact on Construction Inflation

8-27-20 What impact will the pandemic have on Construction Inflation in 2020? Here’s Several inputs.

In April, and again in June, I recommended adding a minimum 1% to normal long-term construction inflation, to use 4% to 5% for 2020 nonresidential buildings construction inflation. Some of my peers were suggesting we would experience deflation. Only twice in 50 years have we experienced construction cost deflation, 2009 and 2010. That was at a time when business volume was down 33% and jobs were down 30%. Currently business volume and jobs are down 10% and by mid-2021 are forecast down 15%.

The Turner Construction Cost index for the Q2 is down 1% from Q1, effectively reporting 0% increase in the index year-to-date. But the Turner index year-to-date (avg Q1+Q2=1183) is still 3.6% higher than the average of Q1+Q2 2019 and 2.3% higher than the avg for all of 2019 (1156). So, while the index appears to show no gains in 2020, through the first six months it is already up 2.3% above the average 2019 index. http://turnerconstruction.com/cost-index

The Rider Levitt Bucknall Q2 2020 index is up 1.6% ytd, up 4.6% from the Q1+Q2 2019 average and up 3.1% above the 2019 average. https://s28259.pcdn.co/wp-content/uploads/2020/07/Q2-2020-QCR.pdf

The U.S. Census Single-Family house Construction Index is up 3.6% year-to-date through July. July 2020 is up 4.2% over July 2019. https://www.census.gov/construction/nrs/pdf/price_uc.pdf

Producer Price Index items for July construction reported by AGC on 8-11-20. Inputs to Nonres construction are down ytd -1.0% through July. Final Demand Nonres Bldgs is up 1.8% ytd through July. See https://www.agc.org/learn/construction-data/construction-data-producer-prices-and-employment-costs and https://edzarenski.com/2020/07/14/producer-price-index-year-to-date-june-july-2020/

R.S.Means quarterly cost index of some materials for the 2nd quarter 2020 compared to Q1: Ready-Mix Concrete 0%, Brick and Block +3%, Steel Items -2%, Wood products +3%, Roof Membrane +7%, Insulating Glass +6%, Interior Finishes -2%, Plumbing Pipe and Fixtures +7%, Sheet Metal +7%. https://www.rsmeans.com/landing-pages/2020-rsmeans-cost-index

U.S. manufacturing output posts largest drop since 1946. Think of all the manufactured products that go into construction of a new building: Concrete, steel, doors, windows, roofing, siding, wallboard, lighting, heating systems, wire, plumbing fixtures, pipe, valves, cabinets, appliances, etc. We have yet to see if any of these will be in short supply leading to delays in completing new or restarted work?

There have been reports that scrap steel shortages may result in a steel cost increase. The U.S. steel industry is in the most severe downturn since 2008, as steelmakers cut back production to match a sharp collapse in demand and shed workers. Capacity Utilization dropped from 82% to 56% in April. Now in mid-August, CapU is up to 61%, still very low. Steel manufacturing output fell by a third and is still down more than 25%. Until production ramps back up to normal levels there may be shortages or delays in delivery of steel products.

Since Q1, the cost of lumber has increase 120%, so expect residential inflation to increase faster than nonresidential. https://eyeonhousing.org/2020/08/average-new-home-price-now-14000-higher-due-to-lumber/ and revised http://nahbnow.com/2020/08/average-new-home-price-now-16000-higher-due-to-lumber/

Contractors have been saying they have difficulty acquiring the skilled labor they need. This has led to increased labor cost to secure needed skills.

But most important, this SMACNA report quantifies that labor productivity has decreased 18% to meet COVID-19 protocols. https://www.constructiondive.com/news/study-finds-covid-19-protocols-led-to-a-7-loss-on-construction-projects/583143/

Labor is about 35% of project cost. Therefore, just this productivity loss equates to 18% x 35% = 6.3% inflation. Even if, for all trades, the average lost time due to COVID-19 protocols is only half that, the added inflationary cost to projects is 3% above normal. I expect the Turner Nonres Bldgs index will reflect some added labor cost in the next two quarterly releases.

Post Great Recession, average nonresidential buildings inflation is 3.9%. For the last five years it’s 4.5%. Residential cost inflation averaged 4.1% and 4.5% for those periods. The 30-year average inflation rate for nonresidential buildings is +3.75%.  

Almost every construction market has a weaker spending outlook in 2021 than in 2020, because approximately 50% of spending in 2021 is generated from 2020 starts and 2020 starts are down.

Typically, when work volume decreases, the bidding environment gets more competitive and prices go down. However, if materials shortages develop or productivity declines, that could cause prices to increase.

Add to these issues the fact that many projects under construction have been halted for some period of time and many more have experienced at least short-term disruption. The delays may add either several weeks to perhaps a month or two to the overall schedule, in which case management cost goes up, or it could add overtime costs to meet a fixed end-date.

We can expect some cost decline due to fewer projects to bid on, which typically results in sharper pencils. But we can also expect cost increases due to materials, labor cost, lost productivity, project time extensions, and/or potential overtime to meet fixed end-date.

I expect non-residential buildings inflation to range between 4% and 5% for 2020 and 2021, perhaps 5% to 6% for residential work.

Construction Spending Forecasts for 2020 Do Not Support Jobs Growth


A current article and several others, based on a sentiment survey, state that there will not be enough construction workers to support growing construction activity next year. I dispute that claim. 

Construction is in demand – but who’s going to do all the work?

I’ve been writing about the disparity in jobs growth exceeding construction activity growth for more than two years. Construction activity has NOT been increasing to support jobs growth.

2020 Construction Spending Increases, but Volume is Down

Expect Construction Jobs Growth to Slow in 2020

To Support Construction Jobs, We Need Volume

There are other construction forecasts that support my argument. It’s important to point out that my forecast is the HIGHEST for 2020. So, just keep in mind, if you consider any other forecast, the condition gets worse.

Seven of the eight firms that provided a forecast for the AIA Consensus Forecast are lower than Construction Analytics forecast for nonresidential work in 2020. AIA Consensus > marked slowdown for nonresidential building

ConstructConnect’s forecast is lower than my forecast for all sectors ConstructConnect’s Winter 2019-20 Put-In-Place Construction Forecasts

FMI’s forecast is lower for all sectors FMI U.S. Engineering and Construction Outlook: Third Quarter 2019 Report

Overall, Construction Analytics 2020 forecast shows a volume gain of 0.6%. Spending increase 4.6%, but average inflation is 4%. Therefore volume increases only 0.6%. That would support growth of about 50,000 jobs. Residential and Non-building Infrastructure show slight gains in 2020 but Nonresidential buildings volume is in it’s 4th year of decline.

ConstructConnect shows a total spending increase of 1.9% and FMI shows a total spending increase of 1%. Both show a slight gain in volume in at least one sector, but with expected inflation of around 4%, both would indicate an overall decline in volume and a decline in jobs.

Spending needs to increase greater than inflation to realize an increase in volume. If volume does not increase, there is no support to add jobs.

Construction Inflation

The level of construction activity has a direct influence on labor and material demand and margins and therefore on construction inflation.

Nonresidential buildings inflation, after hitting 5% in both 2018 and 2019, is forecast for the next three years to fall from 4.4% to 3.8%, lower than the 4.5% average for the last 4 years.

Residential construction inflation in 2019 was only 3.6%. However, the average inflation for six years from 2013 to 2018 was 5.5%. It peaked at 8% in 2013 but dropped to 4.3% in 2018 and only 3.6% in 2019. Forecast residential inflation for the next three years is level at 3.8%.

Nonresidential Buildings and Non-building Infrastructure backlog are both at all-time highs. 75% to 80% of all nonresidential spending within the year comes from starting backlog. Most spending for residential comes from new starts in the year.

2020 starting backlog is up 5.5% across all sectors. However, while a few markets will outperform in 2020 (transportation, public works, office), predicted cash flow (spending) from backlog is up only 1% to 2%. Long duration projects added to backlog and will spread spending out over the next few years.

Residential new construction starts in 2019 (number of units started) gained 4% over 2018. In 2018, starts dropped every quarter after Q1, but then increased every quarter in 2019 and closed out the 2nd half of 2019 at 9% higher than the average of the previous six quarters. New starts measured in dollars dropped slightly in 2019. Spending from new starts fell 5% in 2019 but is forecast up 6% for 2020. Residential construction volume (spending after inflation) in 2019 dropped 8%, the largest volume decline in 10 years. Volume in 2019 dropped to a 4-year low. A volume gain of 2% in 2020 leaves residential still at a 4-year low.

General construction cost indices and Input price indices that don’t track whole building final cost do not capture the full cost of inflation on construction projects.

To differentiate between Revenue and Volume you must use actual final cost indices, otherwise known as selling price indices, to properly adjust the cost of construction over time.

Selling Price is whole building actual final cost. Selling price indices track the final cost of construction, which includes, in addition to costs of labor and materials and sales/use taxes, general contractor and sub-contractor margins or overhead and profit.

Consumer Price Index (CPI), tracks changes in the prices paid by consumers for a representative basket of goods and services, including food, transportation, medical care, apparel, recreation, housing. This index in not related at all to construction and should not be used to adjust construction pricing.

Producer Price Index (PPI) for Construction Inputs is an example of a commonly referenced construction cost index that does not represent whole building costs. Engineering News Record Building Cost Index (ENRBCI) and RSMeans Cost Index are examples of commonly used indices that do not capture whole building cost.

Producer Price Index (PPI) Material Inputs (which excludes labor and margins) to new construction increased +4% in 2018 after a downward trend from +5% in 2011 led to decreased cost of -3% in 2015, the only negative cost for inputs in the past 20 years. Input costs to nonresidential structures in 2017+2018 average +4.3%, the highest in seven years. Infrastructure and industrial inputs were the highest, near 5%. But input costs for 2019 are coming in at less than +1%. Material inputs accounts for only a portion of the final cost of constructed buildings.

Materials price input costs in 2019 slowed to an annual rate of less than 1%.  

Labor input is currently experiencing cost increases. The National construction unemployment rate was recently posted below 4%, the lowest on record with data back to 2000.  The average has been below 5% for the last 18 months. During the previous expansion it hit a low average of 5%. During the recession it went as high as 25%. An unemployment rate this low signifies a tight labor market. This may cause contractors to pay premiums over and above normal wage increases to keep valued workers from leaving. Some premiums accelerate labor cost inflation but are not recorded in published wage data, so aren’t easily tracked. Lack of experienced workers and premiums to keep labor drive labor cost increases higher than wage growth.

Although many contractors report shortages due to labor demand, labor growth may slow due to a forecast 2019-2020 construction volume decline. We might see a jobs decline lag spending/volume decline.

When construction activity is increasing, total construction costs typically increase more rapidly than the net cost of labor and materials. In active markets overhead and profit margins increase in response to increased demand. These costs are captured only in Selling Price, or final cost indices.

Construction Analytics Building Cost Index, Turner Building Cost Index, Rider Levett Bucknall Cost Index and Mortenson Cost Index are all examples of whole building cost indices that measure final selling price (for nonresidential buildings only). The average annual growth for all these indices over the past five years is 4.7%/year. For the last two years, average nonresidential buildings inflation is 5.3%.

  • Long-term construction cost inflation is normally about double consumer price index (CPI).
  • Average long-term nonresidential buildings inflation excluding recession years is 4.2%.
  • Average long-term (30 years) nonresidential construction cost inflation is 3.5% even with any/all recession years included.
  • In times of rapid construction spending growth, nonresidential construction annual inflation averages about 8%. Residential has gone as high as 10%.
  • Nonresidential buildings inflation has average 3.7% since the Great Recession bottom in 2011. It has averaged 4.2% for the last 4 years.
  • Residential buildings inflation reached a post-recession high of 8.0% in 2013 but dropped to 3.4% in 2015. It has averaged 5.8% for the last 5 years.
  • Although inflation is affected by labor and material costs, a large part of the change in inflation is due to change in contractors/supplier margins.
  • When construction volume increases rapidly, margins increase rapidly.
  • Construction inflation can be very different from one major sector to the other and can vary from one market to another. It can even vary considerably from one material to another.

Residential construction inflation in 2019 was only 3.6%. However, the average inflation for six years from 2013 to 2018 was 5.5%. It peaked at 8% in 2013 but dropped to 4.3% in 2018 and only 3.6% in 2019. Residential construction volume in 2019 dropped 8%, the largest volume decline in 10 years. Typically, large declines in volume are accompanied by declines in inflation. Forecast residential inflation for the next three years is level at 3.8%.

A word about Hi-Rise Residential. Probably all of the core and shell and a large percent of interiors cost of a hi-rise residential building would remain the same whether the building was for residential or nonresidential use. This type of construction is totally dis-similar to low-rise residential, which in large part is stick-built single family homes. Therefore, use the residential cost index for single family but a more appropriate index to use for hi-rise residential construction is the nonresidential buildings cost index.

Nonresidential inflation, after hitting 5% in both 2018 and 2019, is forecast for the next three years to fall from 4.4% to 3.8%, lower than the 4.5% average for the last 4 years. Spending needs to grow at a minimum of 4.4%/yr. just to stay ahead of construction inflation, otherwise volume is declining. Spending slowed dramatically in 2019. However, new starts in 2018 and 2019 boosted backlog and 2020 spending will post the strongest gains in four years.

Several Nonresidential Buildings Final Cost Indices averaged over 5% per year for the last 2 years and over 4% per year for the last 5 years. Nonresidential buildings inflation totaled 22% in the last five years. Input indices that do not track whole building cost would indicate inflation for those five years at only 12%, much less than real final cost growth. For a $100 million project escalated over those five years, that’s a difference of $10 million, potentially underestimating cost.

Notice in this next plot how index growth is much less for ENR BCI and RSMeans, both input indices, than for all other selling price final cost indices. From 2010 to 2019, total final price inflation is 110/80 = 1.38 = +38%. Input cost indices total only 106/85 = 1.25 = +25%, missing a big portion of the cost growth over time.

 Nonresidential Buildings Selling Price Indices vs Input Indices

BCI 2010-2020 Firms 12-9-19

Non-building infrastructure indices are so unique to the type of work that individual specific infrastructure indices must be used to adjust cost of work. The FHWA highway index increased 17% from 2010 to 2014, stayed flat from 2015-2017, then increased 15% in 2018-2019. The IHS Pipeline and LNG indices increased 4% in 2019 but are still down 18% since 2014. Coal, gas, and wind power generation indices have gone up only 5% total since 2014. Refineries and petrochemical facilities dropped 10% from 2014 to 2016 but regained all of that by 2019. BurRec inflation for pumping plants and pipelines has averaged 2.5%/yr since 2011 and 3%/yr the last 3 years.

Anticipate 3% to 4% inflation for 2020 with the potential to go higher in rapidly expanding Infrastructure markets, such as pipeline or highway.  This link refers to Infrastructure Indices.

In the following plot, Construction Analytics Building Cost Index annual percent change for nonresidential buildings is plotted as a line against a bar chart of the range of all other nonresidential building inflation indices. Bars represent the predicted range of inflation from various sources with the solid line showing the composite final cost inflation. Note that although 2015 and 2016 have a low end of predicted inflation of less than 1%, the actual inflation is following a pattern of growth above 4%. The low end of the predicted range is almost always established by input costs (ENR BCI is plotted), while the upper end of the range and the actual cost are established by selling price indices.

As noted above, some reliable nonresidential selling price indexes have been over 4% since 2014. Currently most selling price indices are over 5% inflation since 2018.


Reference Inflation PCT 12-17-19

Every index as published has its own base year = 100, generally the year the index was first created, and they all vary. All indices here are converted to the same base year, 2017 = 100, for ease of comparison. No data is changed from the original published indices.

Reference Inflation INDEX 12-17-19

Non-building Infrastructure indices are far more market specific than any other type of index. Reference specific Infrastructure indices rather than any average.

A word about terminology: Inflation vs Escalation. These two words, Inflation and Escalation, both refer to the change in cost over time. However escalation is the term most often used in a construction cost estimate to represent anticipated future change, while more often the record of past cost changes is referred to as inflation. Keep it simple in discussions. No need to argue over the terminology, although this graphic might represent how most owners and estimators reference these two terms.

Construction Volume Growth

For the last three years 2017-2018-2019, construction spending increased 8%, but inflation was 14%. Volume DECREASED 6%. BUT Jobs increased 11%. This ought to leave some people concerned. In this plot of monthly data since 2015, the shaded box shows the period of concern, 2017-2019.

Jobs vs Volume 2015-2020 monthly 1-10-20

And average job openings was 70,000+ the last two years. The only other time a divergence like this has ever occurred is the years leading into the last recession.

Spend-Volume-Esc-Jobs 1-10-20

In 2004-2005-2006, spending increased 30%, but inflation was 28%. Volume increased only 2%. BUT Jobs increased 13%. And job openings increased 20,000/yr. After 15 years of near balanced growth, by the end of 2006 jobs growth exceeded volume growth by 15%. In the next 10 years that disparity never corrected.

Jobs vs Volume 1991-2020 2006 deficit 11-19-19

We can reset the zero baseline to 2006 to see what has happened since 2006.

From 2007 through 2017, jobs and volume were balanced. Since then, the plot below for 2017-2019 looks exactly like 2004-2006 above. So this could raise concern, because,

Jobs vs Volume 1991-2020 2006 deficit reset 11-19-19

if we have just experienced a period in which jobs and volume have been nearly in balance (2007-2016), then if the volume of work is no longer increasing, there is no support for adding jobs. Remember, we started this period with 15% excess jobs, but after 10 years, we swallowed that lump.

This plot is the same data as the first plot, only annually vs monthly. This plot of annual data since 2011 shows not much out-of-balance from 2011 to 2017. The shaded box shows the period of concern, 2017-2019.

Jobs vs Volume 2011-2020 1-10-20

I had been predicting that jobs growth would slow and it has since Q4 2018. The plot below shows the average jobs growth rate for the preceding 12 months. The rate of jobs growth is now at a seven-year low. It could go lower. It probably should go lower, but nonresidential volume declines in 2020 while residential volume increases slightly, so there is a net growth. Non-building infrastructure work is expected to have strong spending  and volume in the next two years due to years of backlog growth.

Jobs trailing 12mo growth 2013-2020 1-10-20

In almost 30 years of data, only six years are way out of balance, 2017-18-19 and 2004-05-06. Current data sure does not indicate there is a lot of construction work out there in need of additional workers. And if jobs are still growing, it certainly does not indicate there should be an increase in job openings, because volume is decreasing. In fact, by all measures, it should indicate job losses.

1-17-20 Job Openings dropped from a recent average near 350,000 to 214,000 in Nov.

The deficit created in the last three years, a 17% disparity in jobs vs volume growth, is similar to the 15% deficit in 2006, preceded by a long period of jobs and volume growth in balance, then going quickly and hugely out-of-balance. That has major implications for labor cost inflation and productivity which could affect schedules, and that’s not the kind of inflation easily tracked in wages. But it’s real.

Next Level of Tariffs Will Be Unknowns

Assessing the impact of this next level tariffs on the cost of construction has now become a nearly impossible task. Tariffs are on PARTS use in manufacture of goods. Who (architect? engineer?) will identify what parts are included in which products used in the building?

For example, look at something simple like light fixtures. The shell, the ballast, the reflector, the shade, the lamps or the wiring could be made in China. Who identifies where parts are made? Who now estimates the share of tariff increase on those parts to determine tariff impact on cost of manufacturing the entire light fixture?

Expand that issue to a pump assembly with valves and pressure gauges. Who identifies which parts in the pump assembly come from what country? How does an estimator determine the cost of manufacturing the pumps, valves and gauges and determine what fraction of total cost has a tariff?

This will inevitably lead to inflation, but it will be hidden inflation, hard to determine if a manufacturer’s price increase for a product is substantiated. This is not like the tariff on mill steel, a 25% tariff on mill steel which represents 25% of final structural steel bid, which represents 10% of the building cost.

At the conceptual or schematic design phase of construction, all the products are not even identified. And the project start date might be two years out. It can’t possibly be determined with certainty what factor should be carried to cover cost increases due to tariffs.

Inflation factors and contingency factors will need to increase to cover unknown costs. This increases the share of the budget that is unidentified, always a contentious issues with owners. Frankly with the margins general contractors or construction managers get for services on a large construction project, these unknown factors, if understated in cost factors, could wipe out the total fee or profit for the job.

This is not a good position to be in, but I don’t yet see how it would be any different.

Brief Notes on Mar2019 Construction Spending Report


Census released March spending today and from my point of view the numbers are showing a surprise downward shift. Nonresidential Buildings and Non-building Infrastructure both showed upward movement as expected but Residential spending posted the eight decline in nine months.

Construction Spending for March posted at $1.282 trillion, 1.5% below (my) expectations. Nonresidential increased BUT Residential is down 2% from Feb. Jan was revised down 4.6% and Feb revised down 5.6%.

Residential spending is now 8% below March 2018. The decline is about half in single family and half in renovations. Multi-family spending is up 11% year/year.

The only monthly gain in residential spending since July 2018 is in Dec, but in the nine months Jul to Mar spending is down 10%. Q1 2019 spending has dropped back to a level of Q1 2017. This is pushing my 2019 residential spending forecast into a decline, 1st decline since 2010.

I’ve posted reasons why I expect upward revisions to residential spending, but I question if revisions can turn around the current 10% decline from last July. It now looks like residential construction spending will NOT post any gains in 2019. That’s more serious than it first appears, since spending needs to increase at least 4% to 5% just to counter inflation. In other words, if residential spending in 2019 posts a 2% decline, real residential volume after inflation would decline by 6% or 7%.

In real volume, after adjusting for inflation, residential construction spending, as of March, is down 12.5% year over year. That hasn’t happened since 2009. Perhaps revisions will recover half that decline, but not all. Contrary to the decline in real volume, in the last year residential construction jobs are UP 3.5%.

Manufacturing currently appears stronger than it is expected to finish the year. Up 6% year-to-date and up 10% from last March, we could see those gains fall off over the next 6 months. Backlog is still very strong, but the schedule of cash flows from old jobs will lead to several months of moderate declines. Initial forecast was for 2% growth in 2019. Current expectations are that manufacturing will finish the year up between 2% to 4%. 2020 will be an extremely strong growth year.

Office spending, similar to manufacturing, could post several months of moderate declines. In fact, my forecast shows office spending declines in 6 out of the next 7 months and finishes the year at the same monthly rate of spending as we are at now. Office is up 8.4% ytd but I expect the year to finish up 4% or less. Initial forecast was up 6% for 2019. New starts in 2018 were up 11% but most of that spending will benefit 2020 when I expect to see growth of 6%.

Commercial spending is currently down 4.8% ytd and 7% lower than last March. It will move slightly lower before it improves, finishing the year down only 1% to 2%. 2020 may not get more than a 1% gain.

Educational spending will finish 2019 much stronger than current spending but the year will only make slight gains over 2018. Current spending is up 5.5% ytd over 2018 but that will taper off.  However, the strong activity in the 2nd half of 2019 will lead to substantial growth in 2020.


More notes will be added in the coming days as I review all other markets in the spending report.

Construction Forecasting – Volume

Feb 26, 2019

Since the bottom of the construction recession year 2011, through 2018 construction spending has increased 67%. During that time construction volume has increased only 32%. All the rest was inflation.

Construction spending is not the only factor for business growth planning. The adjustment for Inflation is the most important factor.

If your company revenues are increasing at a rate of 7% per year at a time when construction inflation is 5%, your business volume is increasing only 2% per year. If you do not factor inflation into your growth projections, you are not forecasting growth properly. Spending is revenue. Volume is spending minus inflation.

Spend current vs constant 2018 2-26-19

Look at the data to the left of the vertical line through 2006. Notice in the bottom plot in the years 2004 and 2005 there is very high spending but very low volume. In 2006 spending was up 4% but real volume declined 3%. For those three years inflation totaled nearly 30%. On the top plot you can see the cumulative effect of several years of high inflation. From 2000 to 2006 spending increased 45% but volume barely moved at all. During this period jobs increased by about 15% and even that outpaced volume. Businesses watched as spending increased 45% in seven years. They increased staff by 15%, but real volume was flat. Heading into the recession construction dollars on the books had been increasing for years but volume was stagnant and companies were top-heavy with jobs.

Addressing the current period 2011 through 2018, if you base business growth on your annual revenue growth, or spending, rather than using inflation adjusted dollars, your forecast for business growth over this eight year time period would be more than double actual volume growth.

Notice the blue bars for annual spending growth in 2017 and 2018 at approximately 4% and 5% respectively. But look at the black lines superimposed on those bars that reflect real volume growth after inflation. There has been only 1% real volume growth in the last two years. Yet jobs increased 8% in two years. Most of the growth in spending is inflation dollars, not real volume growth. Inflation does not support jobs growth.

For 2017-2018 residential spending increased 17% but volume was up only 7%. Nonresidential buildings spending up 6.5% but volume was down 2.5%. Non-building infrastructure spending was up 4% but volume was down by 3%. Inflation across these sectors totaled 7% to 10% for these two years.

Construction jobs, now over 7,400,000 have been over 7,300,000 since summer 2018. The last time jobs were over 7,300,000 was mid-2005 through early 2008, at which point the recession abruptly caused the loss of over 700,000 jobs within 10 months and more than 2 million jobs over the next three years. Jobs are now only 5% lower than the previous high of 7,700,000 in 2006-2007. But construction volume is still 15% below peak constant $ volume reached in early 2006. So the current situation of jobs growth rate exceeding volume growth is worse than it was leading into the last recession.

For 2019 I expect residential and nonresidential buildings to experience a slight decline in volume. I do not yet see a recession as volume picks up again in 2020, but  nonresidential construction jobs in particularly have been increasing faster than volume for several years. Part of that is explained by some nonresidential workers are used to build residential space (hi-rise structure). When the next downturn hits, the potential need to cut nonresidential construction jobs may be quite painful.
