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 labor growth 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 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. Most of the cost of a hi-rise residential building would remain the same whether the building was for residential or nonresidential use. On the contrary, this type of construction is totally dis-similar to low-rise residential, which in large part is stick-built single family homes. Therefore, a more appropriate index to use for hi-rise residential construction is the nonresidential buildings 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.

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.

2020 Construction Forecast Briefs

2020 Construction Forecast Briefs

12-23-19 updated 1-4-20

updated 1-4-20 – The construction spending forecast for 2019 is revised up to $1,304 billion, still a decrease of 0.2% vs 2018. Almost all of the revision up is residential spending that was added in Oct and Sept Census spending revisions released 1-3-20.

The forecast for 2020 construction spending is $1,360 billion, up 4.5% over 2019.

Total Spending increased 9%/yr. from 2012 to 2016, then in 2017 and 2018 slowed to 4%/yr. Spending declined <1% in 2019 and is forecast up 3% to 4% for both 2020 and 2021. 

New construction starts, as reported by Dodge Data and Analytics, increased 7%/year in 2016 and 2017, but only 3% in 2018. Starts are forecast to decline slightly in 2019 and 2020.

New construction starts data captures a share of the total market or a portion of all construction spending, on average about 60% of all construction. In this analysis every market is adjusted by its own individual market share factor.

Applying the market share factors, starts are forecast up slightly in both 2019 and 2020.

Backlog reaches a post-recession high starting 2020, up 20% from 2017, up 100% from 2013. Starts and backlog growth are forecast to remain below 3%/year gain or decline over the next few years. Total spending has only slight gains in 2021 and 2022.

Backlog at the beginning of the year or new starts within the year does not give an indication of what spending will be like within the year. Backlog increases if new starts during the year is greater than spending during the year. An increase in backlog could be a level rate of market activity for a longer duration. It takes several years for all the starts in a year to be completed. Cash flow shows the spending over time. 

The best indicator of future construction activity is the sum of the projected cash flow generated by all the construction starts that have been recorded.

plots updated 1-4-20

Spending cash flow predicted from Dodge Starts and construction spending to date.

Starts CF 2015-2022 1-18-20

A what if scenario in which new construction starts drop by 10%:

On average about 20% of new nonresidential construction starts gets spent within the year started, 50% is spent in the next year and 30% is spent in future years. (For residential the spending curve is more like 70%-30%). If new starts drop by 10% this year, that has only a -2% impact on total nonresidential buildings spending for this year. It would be -5% next year, -3% after. If starts drop a second year, the same impacts occur, shifted one year out, and the total impact for both years is added.

Only about 30% of residential spending within the year comes from backlog and 70% from new starts. If residential new starts drop 10% that impacts total residential spending by 7% in that year.

Nonresidential Buildings starts (excluding Terminals) have reached a new high every year since 2009, but the last three years starts are up only 2% to 3%/year. Every market posted increases in 2017 and 2018. Only Commercial/Retail and Amusement/Recreation declined in 2019. Backlog for Office Buildings, which includes data centers, is up 100%+ since 2015. Spending is still up 4% in 2020 but then with the slowdown in starts forecast in 2020, backlog growth stalls and spending slows in 2021-2022.

Nonresidential buildings markets advancing in 2020-2021 are Educational, Healthcare, Office and Manufacturing. Markets declining are Amusement/Recreation, Commercial/Retail and Lodging.

Non-building Infrastructure starts (including Terminals), up 4% in 2019, are at an all-time high. The two markets with the largest share of new starts are Highway/Bridge and Transportation. Transportation terminals and rail starts are up 30% in the last three years, but backlog has nearly doubled because a large portion of those starts is very long duration projects. Starts are forecast up only 1% in 2020 but backlog peaks in 2021. Spending increases are in the 6% to 8% range at least for the next two years.

Spending in recent years has been boosted by Transportation terminals, Highway and Public Works projects. Power is flat or down slightly.

Residential starts averaged 19%/year growth from 2012 to 2016 but slowed to 5%/year for 2017 and 2018. Starts declined in 2019 and are forecast to decline again in 2020.

The outlook for residential construction spending has improved slightly. Previous forecast had residential spending in 2019 down 6% and 2020 up only 2%. That’s been revised to now forecast 2019 down 4.5% and 2020 up 5%. Spending holds steady in 2021.

If spending is increasing 3%/year at a time when inflation is 5%/year, then real volume is declining. In the last two years, spending increased only 3%, but construction inflation totaled 9%, therefore

in two years, real volume declined by 6%, yet jobs increased by 7.5%.

Since early 2018, jobs have been increasing while construction volume is declining. The volume of work in the last two years does not support jobs growth.

Volume, spending adjusted for inflation in Constant 2017$

Spend Sector 2015-2021 1-4-20.JPG

Nonresidential Buildings will post declines in volume in 2020 & 2021. Residential volume gains 1% in 2020 but slips again in 2021. Non-building Infrastructure will increase volume about 3%/year. Overall, total construction volume declined in 4 of the last 6 quarters and is forecast to drop slightly in 2 or 3 quarters in 2020.

One of the best predictors of construction inflation is the level of activity in an area. When the activity level is low, contractors are all competing for a smaller amount of work and therefore they may reduce margins in bids. When activity is high, there is a greater opportunity to bid on more work and bids can be higher. The level of activity has a direct impact on inflation.

Volume declines should lead to lower inflation as firms compete for fewer new projects. However, if jobs growth continues while volume declines, then productivity continues to decline and that will add to labor cost inflation.

Jobs vs Volume growth set to base year 2011

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

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.

Nonresidential buildings cost inflation for 2018 and 2019 averaged 5%. It’s predicted closer to 4.5% for 2020 and 4% for 2021.

Residential buildings cost inflation for 2018 and 2019 averaged 4%. It’s predicted at 3.75% for 2020 and 2021.

Construction Spending for 2019 finishes flat for Nonresidential Buildings, Up 7% for Non-building Infrastructure and Down 5% for Residential.

Spending UNadjusted for inflation.

Spend Sector 2015-2021 1-5-20

After adjusting for inflation, we see that real construction volume is down. Only Non-building Infrastructure realizes gains in 2019 & 2020. Nonresidential Buildings Volume has been up and down since Q1 2017. Residential volume has been declining since early 2018.

Volume, spending adjusted for inflation in Constant 2017$

Spend Sector 2015-2021 1-4-20

I’m predicting Nonresidential Buildings will post declines in volume in 2020 & 2021. Residential gains 1% in 2020 but slips again in 2021. Non-building Infrastructure will increase at about 3%/year. Overall, total construction volume declined in 4 of the last 6 quarters and is forecast to drop slightly in 2 or 3 quarters in 2020.

Volume declines drive labor to slower growth. We had 6 years of 250,000-300,000 annual growth. Jobs will increase only 150,000 in 2019. In 2020, it could be lower to 100,000.

After 2006, and all the way to 2017, jobs and volume growth were pretty equal. Since 2017 there is a divergence forming. That can’t be sustained.

The plot below shows the predicted spending from modeling Dodge data new construction starts. Overlaying this plot is the actual census spending. You can see the actual value follows pretty closely to the predicted. None of this data is adjusted for inflation.

Spending predicted from Dodge Starts and actual spending to date.

Starts CF 2015-2022 1-18-20

Healthcare and Office are strong markets in 2020, as well as Highway, Transportation and Public Works. Backlog is strongest for Non-building Infrastructure leading into 2021. In the three years since 2017, backlog in Transportation is up 80%, Environmental Public Works up 40%. Within nonresidential buildings, Office backlog is up 60%, Educational is up 15% and Healthcare up 25%. Commercial Retail is the only market with a decline in backlog over this  three year period, down 15%.

Table of Spending by Market Type. updated 1-4-20

Spend Forecast 2018-2022 1-4-20

A reminder, You can’t interpret new construction starts directly to backlog or spending. Starts growth is one thing, but starts data requires cash flow modeling to get spending. Why are Transportation starts for 2018+2019 down 35% but both 2019 and 2020 spending are up? Because in 2017, the year before the data in this table, starts were up 75% and much of that was very long duration work, some that potentially has peak spending 3 to 4 years out, so is still adding a boost to 2020 spending and backlog.

Expect Construction Jobs Growth to Slow in 2020

12-6-19

The construction spending forecast for 2020 indicates 2% growth. But predicted 2020 construction inflation is slightly higher than 4%. So, real construction volume in 2020 decreases by 2%. Jobs should follow volume growth, yet history shows that in non-recessionary periods, even with volume declining, jobs usually continue to increase, but perhaps at a slower rate. 

This plot shows the forecast volume decline in 2020. For the 2020 forecast we already have 80% of all nonresidential spending in backlog. Since new starts account for only 20% of the spending in the year, a 10% drop in new starts from forecast affects only 20% of the spending, so has only a 2% impact on the total. Nonresidential shows flat to moderate gains in 2020.

Residential forecast will be much more dependent on new starts in 2020. About 70% of residential spending within the year comes from new starts within the year, so quick or large changes in new starts has a huge effect on spending for the year. Residential spending is down 10% from early 2018 but residential volume after accounting for inflation is down 15% since that early 2018 peak.

Simply stated, there has not been any volume growth in the last two years to support jobs growth. In constant $, there was no volume growth in any sector in 2018. In 2019 and 2020, only Non-building Infrastructure shows growth, 2%-3%/yr.

This plot shows predicted 2020 jobs growth of 1.5% or just over 100,000 jobs. Since volume is forecast to decline, any jobs growth in 2020 will increase the disparity between jobs and volume growth. The disparity has been increasing since early 2018. It’s a 15% difference right now. Within a year that could be 20%.

Jobs vs Volume 2015-2021 1-4-20

To emphasize the growing difference, look at these two plots, actually, the same plot just modified to account for the 15% bust in 2006.

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

By accounting for the 15% difference in 2006, essentially, resetting the baseline to 2006, it shows all other years up to 2017 were pretty well-balanced growth. With the exception of 2006 and now 2018-2019, for almost every year from 1997 to 2019 jobs grew pretty closely aligned with volume. A big spread occurred in 2006, then growth remained balanced through 2017. The spread now is near the same as it was in 2006.

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

 

Construction jobs growth slowed substantially the last two quarters. I  predicted jobs growth would slow because volume growth had already been declining since early 2018 when volume reached a peak of $1,300 billion. Volume is now $1,170 billion, down 10% in 20 months.  After 6 years of jobs increasing at an average 275,000/year, jobs are up only about +150,000 in the last year, but only +48,000 in the last 7 months. The rate of jobs growth is now the slowest in 7 years. I expect this trend to continue.

The plot of jobs growth below shows current growth rate is below an annual rate of 150,000 jobs/year and it is expected to remain there through 2020, potentially dipping as low as 100,000.

Jobs trailing 12mo growth 2013-2020 12-6-19.JPG

I’d be surprised if jobs start to decline, but that certainly could be envisioned and it would help explain away some of the disparity in growth shown on the Jobs/Volume plot up above.

Construction Spending IS NOT Construction Volume.

I read an analyst report this week that stated construction jobs growth isn’t keeping pace with construction volume growth. The reference appeared to be to construction spending. That fails to apply inflation to convert construction spending to construction volume, so compares apples to oranges. Spending must be adjusted for inflation to get real volume growth. Jobs MUST be compared to volume.

For over two years now, construction volume growth has not supported construction jobs growth we’ve seen. I expected jobs growth to slow down. I’ve been saying this for over a year. This sure looks like it.

For 2018 jobs growth averaged over 300k. Since January 2019 the rate of jobs growth has dropped from 300k to 150k.

Jobs trailing 12mo growth 2013-2019 12-6-19

Current projected new starts data IS NOT supporting construction volume growth for the next 2 yrs. Growth of 3%/yr in non-building infrastructure will be offset by declines in residential buildings and flat nonresidential buildings. Therefore, there is no real volume support for jobs growth.

This plot adjusts construction spending by taking out inflation to get real construction volume growth. Last year of real volume growth was 2016. Yet jobs continue to climb. This can’t continue. The plot above shows it has slowed.

Jobs vs Volume 2015-2020 12-6-19

Construction jobs growth has slowed considerably over last 2Q, as expected. While construction jobs are up about +150k in last year, jobs (through Nov) increased only +48k in the last 7 months. I’m expecting this trend to continue. In fact, I wouldn’t be the least bit surprised to see in the near future some months when construction jobs decline. The fact is, construction volume simply does not support jobs growth.

Total construction volume, spending after accounting for inflation, has been down for 5 of the last 6 quarters. Volume peaked from Q1 2017 to Q1 2018, but the last year of real volume growth was 2016. Volume is flat or down while jobs continue to rise. This can only mean contractors will be at risk of being top-heavy jobs if a downturn comes.

Caution is advised if putting emphasis on construction JOLTS, which has been climbing to new highs. From mid-2006 to mid-2007, JOLTS reached near the then all-time high. But construction volume, starting in mid-2006, was already on the downward slope. Volume peaked in early 2006 and fell 10% by mid-2007. Construction did not begin shedding jobs until late 2006, but mid-2007, job losses were well underway. Within 12 months, more than 500,000 jobs were gone. Within 18 months, construction jobs were down 1.5 million.

Construction spending annual rate will increase by 3% in the next 12 months, but volume in constant $ after inflation will remain flat. In Q42020-Q12021 spending slows to less than inflation, so volume begins a modest decline. Growth of 3%/yr in non-building infrastructure will be offset by declines in residential buildings and flat nonresidential buildings. Jobs will continue to grow and spread the imbalance even more.

The construction jobs slow down has been in the cards for a long time. With all the talk of skilled labor shortages, there’s been little discussion of the unsustainable excess jobs growth. Maybe it’s about time to change the conversation.

Construction Starts > Cashflow > Backlog > Spending

The path from construction starts to spending is not direct and not quite as simple as you might think. Spending is the market activity measure that drives all construction economics, so that’s where we need to get too. With an appropriate modeling technique we can get from new starts to predicted spending in a few steps.

Starts CF 2015-2020 11-27-19

New Construction Starts (construction starts referred to here is Dodge Data & Analytics New Construction Starts) is excellent data for forecasting. The following forecast is entirely developed from starts data. No actual spending is incorporated into this forecast. The purpose is to show that using the data properly can produce an accurate forecast.

The starts data is a survey. As in any survey, starts represents a portion of new construction activity. Study shows the survey size varies with each market from about 40% to 70% of actual. Starts data captures a share of the total market or a portion of all construction, on average about 60% of all construction.

The easiest way to understand this is to compare total annual construction starts to total annual spending. National construction starts from 2016 to 2019 range from $750 billion/year to $800 billion/year, while spending in this period ranges from $1,200 billion/year to $1,300 billion/year. From this we see starts data captures a share of about 60% of the total construction market.

The total starts survey averages about 60% of the actual market. In this analysis every market is adjusted by its own individual market share factor. The adjusted starts represent the full amount of starts that would generate the full amount of spending.

To predict spending activity from new construction starts, the starts data must be spread over time using appropriate cash flow curves. On average about 20% of new construction starts gets spent within the year started, 50% is spent in the next year and 30% is spent in years three and four. The cash flow curves used in this model are specific to each market type and can vary from the average. 

Applying a market survey factor to develop full magnitude of spending and an expected duration for all starts, depending on market type, to produce a forecast cash flow from starts data, the predicted pattern of spending is developed. The factors have been shown to produce a reliable prediction of total future market activity.

Forecast Summary Table National 10-14-19

Backlog at the beginning of the year or new starts within the year does not give an indication of spending within the year. New starts within the year could contribute spending spread out over several years. Total cash flow in the year, or spending, could include cash flow from projects that started or entered backlog years ago.

Backlog increases if new starts during the year is greater than spending during the year. However, an increase in backlog does not necessarily indicate there will be an increase in market activity. An increase in backlog could represent a level rate of market activity, but for a longer duration.

Cash flow provides the best indicator of how much and when spending will occur. Cash flow from all previous starts gives a prediction of how spending will change monthly from all projects in backlog. Cash flow totals of all jobs can vary considerably from month to month, are not only driven by new jobs starting but also old jobs ending, and are heavily dependent on the type, size and duration of jobs.

Total of all national construction starts increased every year since 2008. New starts slowed to +2% in 2018 and are forecast at a potential decline of 0.2% in 2019. Backlog is still up leading into 2020 but after that starts and backlog are forecast to remain flat or decline over the next few years. Total spending declines in 2022. However, as the next tables will show, work distribution is uneven with residential declining and nonresidential up.

Forecast Total All Markets Table National 10-14-19

Nonresidential Buildings starts (excluding Terminals) reached a new high every year since 2009. The last three years starts are up 3% to 4% per year. Every market posted increases in 2017 and 2018. Only Commercial/Retail declined in 2019. The largest increases over the last two years were Educational and Office Buildings. Spending is still strong in 2020 but then with the slowdown in starts forecast in 2020, backlog growth stalls and spending slows in 2021-2022.

75%-80% of all Nonresidential Buildings spending within the year will be generated from projects that were booked in starting backlog at the beginning of the year.

CF Forecast NonResidential Table National 10-14-19

Nonbuilding Infrastructure markets total spending amounts to only about 70% of nonresidential buildings markets. The largest infrastructure markets are Highway/Bridge and Power but the largest increases in new starts recently are in Transportation (including all terminals) and Environmental Public Works. Transportation starts are up 25% in the last last three years and backlog to start 2020 is up 80%. Public Works starts are up 22% and backlog is up 30%

Nonbuilding Infrastructure starts can be erratic with a long pattern of up then down years. Starts (including Terminals) gained only 2% in 2019 but that is only low because Power, the largest market overall saw starts decline by 7%. Total infrastructure starts are at an all-time high.

CF Forecast NonBuilding Table National 10-14-19

Infrastructure backlog peaks in 2020 and remains high into 2021. Spending increases are in the 6% to 8% range at least for the next two years. Infrastructure projects typically have the longest duration. Projects contribute spending sometimes up to 5 or 6 years. The largest spending increases in 2020 are in Transportation and Highway projects.

The Residential table shows that most of the spending in any year is cash flow from new starts. For short duration residential spending, single-family residential and renovations work, approximately 75% of the spending occurs in the year of the starts and 20% in the following year.

Forecast Residential Table National 10-14-19

For long duration residential spending, typical of multifamily residential, approximately 50%-55% of the spending occurs in the year of the start, 35%-40% in the next year and only 5%-10% occurs two years out.

Only 25% (for short duration SF and Reno) to 50% (for longer duration MF) residential spending within the year comes from work that was booked in backlog at the beginning of the year. The performance of residential spending in the year is very much dependent on new starts.

The level of activity has a direct impact on inflation. When the activity level is low, contractors are all competing for a smaller amount of work and therefore they may reduce bids. When activity is high, there is a greater opportunity to bid on more work and bids can be higher.

Residential construction saw a slowdown in inflation to only +3.5% in 2015. However, the average inflation for six years from 2013 to 2018 was 5.5%. It peaked at 8% in 2013. Residential construction spending dropped an unexpected 6% in 2019 and after adjusting for inflation that is a 10% decline in construction volume. Typically, large declines in volume are accompanied by declines in inflation. National average residential construction inflation for 2019 is now at 3.8%. 2020 is forecast at 3.75%.

Nonresidential Buildings indices have averaged 4.4% over the last five years and have reached over 5% in the last three years. But spending slowed dramatically in 2019. This forecast indicates spending in most nonresidential buildings markets will gain little in 2019, the slowest rate of growth post-recession. However, new starts in 2018 and 2019 boosted backlog and 2020 spending will post the strongest gains in four years. Strong gains in spending historically has led to accelerated inflation. National average nonresidential buildings construction inflation for 2019 is now at 4.8%. 2020 is forecast at 4.2%.

Construction Statistics – Behind The Headlines

Examples of how commonly reported construction data can often be misused – Construction Spending and Construction Starts

 

Construction Grew $41 billion, 3.3%, from 2017 to 2018

An increase in construction spending is often referred to as growth for the industry, but that is incorrect. Construction spending measures the change in the dollar value of work performed, not the volume of work performed.

Crate of Apples

The difference between spending (or revenue) and volume can be explained by a simple example, the Crate of Apples. A farm stand sold a crate of apples last year for $100. Costs have gone up. Today the same size crate of apples sells for $110. Farm stand revenues increased 10%, but the amount of business volume did not increase. Volume of sales is still one crate of apples. All the increase in revenue was inflation.

The $41 billion increase in construction spending from $1.266 trillion in 2017 to $1.307 trillion in 2018 is a 3.3% increase. However, construction inflation for that period averaged 4.7%. Construction inflation adds only cost, not volume, to the amount of work. Construction spending is measured in current dollars, actual dollars spent within the year in the value that year. Construction volume is measured in constant dollars, adjusted for inflation, so any and all years can be compared to each other.

Real construction volume adjusted for inflation actually decreased 1.4% from 2017 to 2018.

Total Construction volume, after accounting for inflation, has been down for five of the last six quarters. Construction volume peaked from Q1 2017 to Q1 2018, is now down 6% from the 2018 peak.

Spend current vs constant 2019 10-3-19

Construction volume is not directly reported. It is not a commonly referenced industry measure reported in the news. But it is a more important indicator of activity in the industry than spending. Volume is found only through analysis of spending and inflation data.

Another common misrepresentation using spending data relates to jobs growth. Jobs growth is often compared to spending growth where a 3% to 4% increase in jobs from year to year is substantiated if we have a similar 3% to 4% growth in spending. However, current $ spending is not yet adjusted for inflation and does not represent growth in real volume of work. Jobs must be compared to volume. Real volume increases are represented by constant $, or construction spending adjusted for inflation.

In the last 2 years jobs have increased by about 8% but real construction volume has decreased by about 6%. In recent years, construction volume has not supported jobs growth.

Construction Starts Predict Changes in Spending

Two very important criteria must be known about new construction starts in order to properly predict spending.

1st – To predict spending from new starts, the starts data must be spread over time using an appropriate cash flow curve. A simple illustrative spending pattern for nonresidential buildings starts, or a typical cash flow curve, for total starts within a year is: 20% of the revenue gets spent in the 1st year, 50% in the 2nd year and 30% in the 3rd year. This shows predicting spending in any given year is dependent on several previous years of starts.

Starts vs Spending Cash Flow Illustrated 10-5-19

Multi-billion $ highway projects, manufacturing facilities, power projects and transportation terminals often have much longer duration cash flow curves. In other words, if your intent is to predict construction spending in 2019, you need to know what starts were at a minimum in 2017 and 2018, and in many cases back to 2016 or even 2015.

Starts spread over time with cash flow curves predict spending.

Starts CF 2015-2020 11-27-19

2nd – For new construction starts survey sample to be used to compare to itself from year to year to predict growth in spending, sample size must be known. Starts data captures a share of the total market or a portion of all construction, on average about 60% of all construction. The easiest way to see this is compare total construction starts to total spending. Starts from 2016 to 2019 range from $750 billion to $800 billion while spending in those years ranges from $1,200 billion to $1,300 billion. From this we see starts capture a share of the total market. Any time a survey of a total population is used to forecast the total, the survey share of total must be considered.  If sample size is not constant, the apparent growth in starts does not all reflect real growth in spending.

Amusement/Recreation is an example that shows starts that generate a predicted cash flow pretty well balanced with actual spending from year to year. The share of starts in the survey is fairly consistent never varying from 63% to 66% from year to year.

Starts SHARE Amuse 10-5-19

Office provides an example of variation in sample share of total. Starts generate predicted cash flow that increased substantially from 49% to 57% and remained higher compared to actual spending.

Starts SHARE Office 10-5-19

Office starts increased from $21 billion in 2013 to $50 billion in 2019. This data generates the predicted cash flow that is compared to actual spending. To predict total spending from unadjusted starts, unadjusted starts CF$ are factored up (divided by) share of total market. If the share of market captured in the survey remained constant then the predicted spending would remain close to 50%. 

CF$ Predicted/Actual shows that Cash Flow Share of actual spending was 48%-50% for several years but then jumped to 56%-57%. The predicted cash flow generated from the increase in starts is not entirely representative of an increase in spending but represents the combined value of the expected increase in spending and an increase in share of market data captured.

Starts cash flow and starts survey share of total spending are never directly known or published. These factors are found only through analysis of the data.

The Educational market data shows a similar situation as Office data. Starts generate predicted cash flow that increased substantially compared to actual spending.

Starts SHARE Educat 10-5-19

Starts data generate predicted cash flow to forecast spending. This requires tracking share of total market captured in the starts survey data to account for any growth in the market share captured vs growth in predicted spending.

 

 

Prelim 2019-2020 Construction Spending

Note 11-8-19 on September spending: Construction Spending in September is up 0.5% from August and still down 2.2% year-to-date (ytd) from 2018. Spending in Q3 averaged the same as Q1.  Qtr/Qtr spending this year has ranged +/- 1%. Total 2019 spending will be down 1%. I’m expecting 2019 Nonresidential Buildings spending up less than 1%, Non-building Infrastructure up 7% and Residential spending down 6%.

10-3-19

Construction Spending in August is down slightly from July and down 2.3% year-to-date (ytd) from 2018. Spending for the last three months has remained flat. Qtr/Qtr spending has ranged +/- 2% for the last five quarters. Total 2019 spending will be down 0.5%. I’m expecting 2019 Nonresidential Buildings spending up 1%, Non-building Infrastructure up 8% and Residential spending down 6%.

Residential construction spending, down for six consecutive quarters, is now down 11% from Q1 2018. Residential volume (spending minus inflation), also down for six quarters, is down 16% from the Q1 2018 peak.

Some markets spending totals for 2019: Lodging +11%, Office +10%, Amusement and Healthcare both +5%, Commercial/Retail -14%, Highway +11%, Power +7%, Transportation +6%, Environmental Public Works (combined) +12%.

2020 forecast Starting Backlog for Nonresidential Buildings is currently up 6% and for Non-building Infrastructure is up 9%. Strong backlog leading into 2020 will increase spending in most nonresidential markets. Exceptions are: Commercial/Retail and Power backlog will decline. Residential spending is 65% dependent on new starts but Nonresidential spending is 80% dependent on backlog.

Spend Forecast 2018-2019-2020-2021 11-19-19

Forecast growth for 2020 is welcome since real construction volume, after accounting for 4% to 5% inflation, has been down for five of the last six quarters. Annual construction inflation since 2011 has been as high as 5.8%. For the last 3 yrs it has averaged 4.6%/yr. Construction spending for the last 3 years avg. annual growth is only 2.4%. When construction spending is lower than inflation, real volume is declining. Jobs must be compared to volume.

Total construction volume after inflation (quarterly avg) reached a peak in the 1st quarter of 2017 (which was then matched again in Q1 2018) and is now down 6% from the peak. Most of the volume decline was in Residential. Only Infrastructure has seen volume gains in the last two years. We have seen jobs growth slow in the last year, but the disparity between construction volume and jobs growth is the greatest ever. I expect to see a much more significant slow down in jobs growth.

Jobs vs Volume 1991-2019 10-3-19

Backlog growth over the past two years will provide the base for Nonresidential construction spending increases in 2020. Major backlog increases from 2018 to the start of 2020 are: Educational +12%, Office +25%, Commercial/Retail -14%, Highway +16%, Transportation +45% and Environmental +23%.

The forecast for 2020 spending is total $ up 3%, but Residential spending will be flat to down slightly.

Construction Spending Forecast strength over the next 18 months is all nonresidential. Current spending seasonally adjusted annual rate (SAAR) vs SAAR at the end 2020 shows Nonresidential Buildings now at $450bil will end 2020 at $500bil and Non-building Infrastructure, now at $340 billion, will end 2020 at $375bil. Residential is now at $510bil but will move up slightly then down to finish 2020 at $500bil.
