A few bullets from this presentation
- Construction Starts is not construction spending
- Cash flow = Spending = Revenue
- Revenue is not Volume of work
- Spending minus inflation = Volume
- Understand what’s in an Index to avoid misguided inflation adjustments
- We can’t ignore productivity
- Spending activity has just as much influence on inflation as labor and material cost.

5-1-17 Updated construction spending forecast for 2017. Actual spending is included through March data, first release 5-1-17. Forecast spending includes predictions based on Dodge Data & Analytics (DDA) construction starts through March, released 4-21-17.
Reference Construction Economic Outlook 2017 posted January 2017
5-1-17 Update Overview
Construction Spending in March posted a seasonally adjusted annual rate (SAAR) of $1,218 billion, down 0.2% from February. February was revised UP by 2.3%, and March data is still subject to revisions, usually upward, the next two months. January was revised UP 1.6% from the initial release.
The 1st release of spending is always being compared to a previous month and a previous year that have already been revised, almost always up. Upward revisions to monthly construction spending in 2016 have been as high as 3.4% and for the year average 1.1%/mo. In the last 48 months, the 1st report of construction spending was down vs the prior month 20 times. The initial value was subsequently revised UP 47 times. After revisions, only nine months were down compared to the prior month.
Total Construction Spending for Q1’17 is 3.5% higher than I predicted in my initial 2017 forecast posted 1-7-17. Construction spending growth from Q4’16 to Q1’17 gives 2017 the 2nd best quarter to quarter start in 10 years, just shy of 2014 which posted the best spending growth since 2005. Nearly all the greater volume in spending over my original 2017 forecast is in residential construction, which, for the last four months, has posted much stronger new starts and spending than anticipated based on DDA projections.
Year over year total spending:
- Jan17r/Jan16 = 4.7%
- Feb17r/Feb16 = 5.5%
- Mar17/Mar16 = 3.6%
Based on history, it is likely that Mar17 will get revised UP. (note: with the 2nd release of March spending, the Mar17 year-over-year value was revised up from yoy 3.6% to 5.0%. The initial Apr17 yoy value was posted as up 6.7% from Apr16. Year-to-date total through April is up 5.8% over 2016, and that will most likely be revised higher.)
Total construction spending in 2017 is now forecast to finish at $1,263 billion, an 8.5% increase vs 2016, supported by a 4th consecutive year of strong performance in nonresidential buildings and a very strong start in residential spending. The SAAR of spending will range from near $1.2 trillion in January to $1.3 trillion in the 4th quarter.
A significant indicator for 2017 construction spending performance is that 2017 year-to-date (YTD) spending is up 4.9% compared to a very strong 1st quarter 2016. In the 2nd quarter 2016 spending dropped and did not return to the Feb-Mar 2016 level until Sept-Oct 2016. In 2017, although growth will slow (but still remain positive) in the 2nd quarter, by Sept-Oct spending will be 5% higher than March. The six months Apr-Sept 2017 compared to the same period 2016 will show growth of more than 8%.
The SAAR of spending on a “current dollar” basis (before adjusting for inflation) is now at an all-time high, just barely eclipsing the highs of early 2006. By the 4th quarter of 2017 spending will be 5% above the previous 2006 highs on a “current dollar” basis. However, on a “constant dollar” basis (adjusted for inflation) we are still 13%-14% below peak spending, perhaps five more years away from the real inflation adjusted 2006 peak.
The SAAR of Residential construction spending increased 6% in the last 3 months. It is up 5.3% from Q4’16 to Q1’17. March YTD (=Q1 2017 total) is up only 8.5% from Q1 2016, because Q1 2016 was exceptionally strong. I’m forecasting residential construction 2017 growth of 8% to 10%. Residential spending in 2017 is forecast at $512 billion, 10.2% higher than 2016.
Total Nonresidential construction spending is up 2% Q1’17 vs Q4’16 and up 2.5% vs Q1’16. Predicted cash flows indicate a strong growth pattern for 2017. I expect total nonresidential spending to finish the year up 7%. Nonresidential construction is better understood by looking at the parts, buildings and infrastructure.
Construction spending for Nonresidential Buildings in Q1’17 is up 1.6% vs Q4’16 and up 6.6% vs Q1’16. The most recent 3-month average seasonally adjusted annual rate (SAAR) is $427 billion, now less than 4% below the previous peak of $444 billion in 2008. By midyear 2017 the SAAR will reach a new all-time high and at year-end it will be near $460 billion.
Nonresidential buildings 2017 starting backlog on January 1, 2017 was 47% higher than at the start of 2014, the beginning of the current growth cycle. Spending within the year has two sources; that generated from new starts within the year and that generated from starting backlog. For nonresidential buildings, spending within the year from starting backlog has increased every year since 2014 and in 2017 it will be 42% higher than 2014.
Nonresidential Buildings spending in 2017 is forecast at $447 billion, 9.0% above 2016. Office spending will lead 2017 with 25%+ growth. Commercial, Lodging and Educational markets are all expected to post strong gains over 10%.

Construction spending for Nonbuilding Infrastructure Q1’17 is up 3.8% vs Q4’16, but down 1.8% vs Q1’16. Nonbuilding infrastructure 2017 growth is expected at about 4%-5%.
Non-building Infrastructure, following two down years, will increase by 4.8% to $305 billion. Infrastructure growth is being led by a very high volume of power generation and pipeline work, up only slightly from Q1’16, but up 10% from Q4’16. Although new infrastructure starts were down in 2016 and are expected to decline again in 2017, the amount of work in backlog at the start of 2017 is the highest its ever been and spending in 2017 is forecast at an all-time high.
For Non-building Infrastructure details see Infrastructure Outlook 2017
Private spending is the highest since Q1 2006. Public spending YTD 2017 vs 2016 is down 7% ONLY because the 1st quarter of 2016 was the highest quarter since 2010, elevated due to highway and bridge spending. Educational and Highway/Bridge, the largest two components, make up almost 60% of public spending. The quarterly average of Public spending has been increasing since Q2’16. By the end of Q2’17 YTD public spending will be up 2.5%.
For all of 2017 Private spending will increase 9%. Public spending could increase 7%, with half the gains coming from educational spending.
Starting Backlog is the Estimate-to-Complete (ETC) value of all projects under contract at the beginning of the period. The sum of all ETC represents current backlog. While continued growth in backlog is most important, the predicted cash flow from backlog and new starts is necessary for predicting future spending.
Revenues from starting backlog account for 75%-80% of all nonresidential construction spending within the year. Not only was nonresidential starting backlog at the highest ever coming into 2017, but also spending from backlog is predicted up by 5% and 2017 new starts are predicted up 8%.
Due to the shorter duration of residential projects, nearly 70% of spending within the year is generated from new starts. Unlike nonresidential, backlog does not contribute nearly as much spending within the current year. If no new work started within the year, within a matter of a few months there would be no backlog ETC left to support the industry.
Construction starts, which generate construction spending (cash flow) over the next several years, were originally reported in 2016 as up only 1% from a remarkably strong 2015. However, Jan-Feb-Mar 2016 starts have recently been revised up by a whopping 16%, and the historical trend is that every monthly value in the previous year for the last eight years has been revised up. This adds to predicted cash flow, so has an immediate affect of raising predicted 2017 spending. 2016 revisions-to-date and expected revisions are on track to raise 2016 starts up to 6% growth over 2015.
Starts that are being reported for the current year are always being compared to a previous year that has been revised up, so starts growth is always understated. So far, starts for the 1st quarter of 2017 have been much stronger than expected. Starts year-to-date are down 1.5% from the upward revised 2016 totals, however the historical revision has been in the range of 3.5% to 5%. So, the actual growth in new starts has been remarkably strong, better than forecast in October, and is adding to the basis for increased forecast in future 2017 and 2018 spending.
Headlines of construction spending declines are almost always premature.
April construction spending 1st release was issued on 6-1-17 by U. S. Census. The initial release shows April DOWN 1.4% from March, a value many news sources have reported as “construction spending is slowing”, “one of the largest drops in six years”, “an unexpected slump”, “spending continued to demonstrate substantial weakness.” I’ve written about this numerous times but it’s worth repeating again. Construction spending almost always gets revised UP in the following month after 1st release. Average revision so far in 2017 is +1.8% and for the last 18 months +1.3%. Monthly construction spending has now been revised UP every one of the last 43 consecutive months.
Headlines of construction spending declines are almost always premature.
Construction spending is almost always a miss when first posted, until it gets revised up in the following monthly report to show is it almost never a miss.
The 1st release of March construction spending came out May 1. This initial release indicates a decline of 0.2% from February. Keep in mind, all 12 monthly reports in 2016 were subsequently revised up. Nine times in the previous 14 months, the 1st report of spending was down vs the prior month. After revisions, only three months were down compared to the prior month.
In the last 48 months, the 1st report of spending was down vs the prior month 20 times. 47 times the initial value was revised UP. After revisions, only nine months were down compared to the prior month.
Monthly construction spending has been revised UP every one of the last 42 consecutive months.
The 1st release of spending is almost always being compared to a previous month and a previous year that have been revised up. Upward revisions to monthly construction spending in 2016 have been as high as 3.4% and for the year average 1.1%/mo. So, a 0.2% mo/mo decline s probably not a decline at all after revision, and there will be a revision, most likely UP.
After spending is first published it is revised in each of the two following months. Then all the values for the entire year are revised with the May data release the following year.
Some specific markets construction spending revised after 1st release (2016 data). These markets represent almost 50% of nonresidential data.
- Office revised UP 8 of 12 months (average of all 12 +1.1%)
- Commercial UP 9 of 12 avg 1.8%
- Educational UP 10 of 12 avg 1.8%
- Power UP 12 of 12 avg 3.6%
Don’t like the year-over-year (yoy) Construction Spending percent change? Just wait until next month. It’s going to be worse!
The latest year over year construction spending through February is up 3.0% compared to Feb 2016.
March data yoy comparison is going to come in at or under 2%. But construction spending is increasing!
It just so happens March 2016 was an outstanding month. That lowers the yoy percent change, but March 2016 is the anomaly.
Yoy doesn’t indicate if this year is doing poorly or if that month last year was a great month.
Yoy doesn’t indicate what direction current spending is taking.
Yoy compares an unadjusted 2017 value to an upwardly adjusted 2016 value.
For the last 40 consecutive months the construction spending value has been revise UP. But not until after major news media gets to report that yoy construction spending did not meet expectations.
For the last 18 months the average adjustment to construction spending after the 1st release of data +2%.
The yoy and mo/mo percentage change in the 1st release was understated every time.
For Q1 2017, yoy values are expected to range between 1.5% and 3.5%. 2017 is expected to finish the year up 6% over 2016.
Dodge released the Feb 2017 construction starts today. For the Jan and Feb reports, I think the most relevant piece of information in this report is that Jan and Feb 2016 values were revised up, in total by 15%. That alone has added 2% to total 2016 starts.
In the Dodge October Construction Outlook report, construction starts total for 2016 were predicted at $676 billion, and 2017 at +5%, or $713 billion. Revisions so far have increased 2016 actual to $692 billion. 2016 is on track to go above $700 billion, and at +5%, 2017 could reach $735 billion.
New 2017 starts are being compared to upwardly revised 2016 values. That understates 2017 performance. Dodge Data provides revised starts a month later and 12 months later. In every monthly release, the previous month is revised AND the last year’s year-to-date is revised. Dodge does incorporate other (minor) revisions at a later date, but the “12 month” revision to the previous year-to-date values captures the largest part of all revisions.
This February report includes revisions to the total 2016 YTD, Jan+Feb 2016. The 2017 values won’t get that equivalent “12 month” revision until next year. Therefore, Current year YTD values (not-yet-revised) are being compared to the previous year YTD revised values which has the affect of making current YTD growth appear lower than it should.
In the last 10 years the YTD revisions have always been up. Usually, most of the revisions occur to nonresidential buildings, about 5% to 6% per year, with only a 3% to 4% revision to infrastructure and only 2% to residential.
So far in 2017, year-to-date 2016 values for Jan+Feb have been revise up by 15%. That’s a 2% revision to the 2016 annual total. Already in just the first two months, on an annual basis, nonresidential buildings have been revised up 2%, non-building infrastructure up 4% and residential up 1.3%.
While the 2017 YTD value this month is noted as down 4% compared to last year, keep in mind last year’s value was just revised up by 15%. So, much of the reason 2017 is down is because 2016 values have had revisions applied and 2017 have not. To me, this latest report looks up.
Starting Backlog is the Estimate-to-Complete (ETC) value of all projects under contract at the beginning of the year. Projects in starting backlog could have started last month or last year or three years ago. The requirement is that those projects have not reached their end-date and some portion of the revenues generated by those projects is still ETC. The sum of all ETC represents current backlog.
A cash flow schedule of all ETC backlog and predicted new starts provides a tool to predict future spending. The $ reported here are the results of a cash flow analysis using Dodge Data & Analytics Construction Starts. Do keep in mind the DDA Starts value represents a survey of about 50% to 60% of the industry. While the percent change of values from year to year is relevant, the $ value does not compare directly to the actual spending $ values.
It is not enough to look at just the change in starts or the change in backlog to get an indication of the strength of the market. While continued growth in backlog is most important, the predicted cash flow from backlog and new starts is necessary for predicting future spending.
The last time nonresidential buildings experienced a decline in starting backlog was 2013, Total construction spending on nonresidential buildings in 2013 registered a weak 0.8% gain. Since 2013, nonresidential buildings starting backlog is up 60%, reaching a new all-time high at the beginning of 2017. The previous high in 2009 was $241 billion. In 2016 it was $230 billion. For the start of 2017 it is $248 billion.
Revenues from starting backlog account for 75% of all nonresidential buildings construction spending within the year. If no new work started within the year, by year end there would be only 25% of the total in backlog needed to support the industry.
Not only is starting backlog higher coming into 2017, but also spending from backlog is predicted up by 5% and 2017 new starts are predicted up 8%. New starts are very strong in Office, Lodging, Educational, Healthcare and Amusement/Recreation.
This supports my predictions that 2017 will be another banner year for spending on nonresidential buildings, up a strong 10% from 2016. Similar growth is expected in 2018. This will produce a new high in current dollar spending, but will still be 15% below the constant $ all-time highs.
(edit 3-21-17 updated table)
Non-building infrastructure experienced declines in starting backlog in 2012 and 2015. Fortunately, in both of those years, new starts were up. For the last eight years infrastructure starting backlog has been near $200 billion, +/- $10 billion. In 2008, the last pre-recession year, backlog stood at $178 billion. At the beginning of 2017, non-building infrastructure backlog is at an all-time high, $243 billion, up 36% from 2008. In the last two years starting backlog is up 20%.
Revenues from starting backlog account for 80% of all non-building infrastructure construction spending within the year. However, because infrastructure projects are long duration, only about 60% of total backlog gets spent within the year. If no new work started within the year, by year end there would still be 55% of the total in backlog needed to support the industry.
In 2016, although starting backlog was up, new starts were down and spending from backlog was also down. That cemented a decline in spending in 2016. New starts in 2016 declined for power, highway, transportation and public works, but due to long duration projects contributing to strong backlog in these markets, spending will be up in all except public works. New infrastructure starts in 2017 are predicted down 5%, but spending from backlog is predicted to increase by more than 10%, and that more than offsets the decline in new starts. 2017 will post a solid gain of 4% to reach a new high in spending and that is expected to increase again in 2018.
Residential new starts hit bottom in 2009 and starting backlog hit bottom in 2010. Residential on average has the shortest duration and new starts has a dramatic impact on the amount of available work. Both new starts and backlog are up about 300% from the lows. New residential starts have increased every year since the 2009 bottom, but are still lower than 2006.
Due to the shorter duration of projects, nearly 70% of residential spending within the year is generated from new starts. Unlike nonresidential, backlog does not contribute nearly as much. If no new work started within the year, within a matter of a few months there would be no backlog ETC left to support the industry.
Coming into 2017, starting backlog is up, and new starts are up and spending from new starts is up. But the rate of growth in new starts and spending from new starts is slowing. This is not unexpected after 4 years (2012-2015) of new starts growth averaging greater than 20%/year. The last two years it’s 12%/yr. This leads to a prediction of future spending increases ranging between 5% to 7% for the next two years.
A major construction industry news source has a series of articles referencing Dodge Data New Construction Starts, first listing starts data, but then incorrectly refers to the data as construction spending and looks at the trend in values to predict if construction spending in 2017 will rise or fall. This is incorrect use of data and misrepresents Dodge Data New Starts. The starts data as it is being used isn’t a valid indicator to get a spending projection in the next year.
New Starts for 2016 is the total value of project revenues that came under contract in 2016. The values reported by Dodge are a sampling survey of about 50% to 60% of the industry. The percent change in values is very useful. The total dollar volume is not comparable to actual spending.
The entire value of a project is considered in backlog when the contract is signed. Projects booked on or before December 2016 that still have work remaining to be completed are in backlog at the start of 2017. Simply referencing total new starts or backlog does not give an indication of spending within the next calendar year, particularly for infrastructure and residential. Projects, from start to completion, can have significantly different duration. Whereas a residential project may have a duration of 6 to 12 months, an office building could have a duration of 18 to 24 months and a billion dollar infrastructure project could have a duration of 3 to 4 years. So new starts within any given year could contribute spending spread out over several years.
Backlog at the start of 2017 could include revenues from projects that started last month or as long as several years ago. For a project that has a duration of several years, the amount in starting backlog at the beginning of 2017 is not the total amount recorded when that project started, but is the amount remaining to complete the project or the estimate to complete (ETC). And all of that ETC may not be spent in the year following when it started, dependent on the duration remaining to completion.
The only way to know how much of total starts or total backlog that will get spent in the current year and following years is to prepare an estimated cash flow from start to finish for all the projects that have started, over the past few years. The sum of the amounts from all projects in each month gives total cash flow in that month, or monthly spending in that year. Spending in any given month could have input from projects over the last 36 months. That’s what shows the expected change in spending.
Construction Starts provide the values entering backlog each month. Except for residential, new project starts within the year contribute a much smaller percentage to total spending in the first year than all the backlog ETC on the books at the start of the year. New residential projects contribute the most to spending within the year started because generally residential projects have the shortest duration. Residential projects started in the first quarter may reach completion before the year is over. New infrastructure projects generally have the longest duration and may contribute some share of project value to backlog spread over the next several years.
The following table clearly shows there is not a correlation between starts in any year with spending in the following year. The practice of using construction starts directly to predict spending in the following year can be very misleading in an industry that relies on data for predictive analysis to plan for the future. Not only does it not predict the volume of spending in the following year, it does not even consistently predict the direction spending will take, up or down, in the following year. It ‘s not a good use of data.
Dodge Data New Construction Starts is a powerful piece of data if used properly.
Headlines of construction spending declines are almost always premature.
The 1st release of January construction spending came out March 1. This initial release indicates a decline of 1% from December. Keep in mind, all 12 monthly reports in 2016 were subsequently revised up. Eight times in 2016 the 1st report of spending was down vs the previous month. After revisions, only two months were down compared to the previous month.
Monthly construction spending has been revised UP every one of the last 39 consecutive months. Since August 2013, the first report indicated a decline vs. the previous month 17 times. After revisions, there remain only seven real month/month declines in 39 months.
The 1st release of spending is almost always being compared to a previous month and a previous year that have been revised up. Upward revisions to monthly construction spending in 2016 have been as high as 3.4% and for the year average 1.1%/mo.
After spending is first published it is revised in each of the two following months. Then all the values for the entire year are revised when the May data release is issued on July 1 of the following year.
Most changes in monthly spending are predetermined.
Spending that occurs this month is generated from all the projects that are ongoing, some that started many months ago. In fact, some projects may have started three or four years ago. For instance, the largest decline in public spending this month is highway work. Although it has one of the smallest percent changes ( only -3.3% vs -12% to -16% for other markets), it is the largest share of total public spending. A very large amount work, 40% above normal, started in 2013 – early 2014. Some of that work is just now finishing. It could be seen a year ago in the cash flow models that a very large sum of work would be ending sometime in Q4’16 or Q1’17. It often occurs that the largest changes in monthly spending are driven by work ending rather than new work beginning.
Nonresidential buildings has the largest backlog ever.
Both Residential and Non-building Infrastructure will increase in 2017 after brief slowdowns but Nonresidential Buildings will lead construction spending in 2017, accounting for more than half of all 2017 growth. Office and commercial retail and then educational provide the most dollar volume growth in 2017.
Nonresidential buildings 2017 starting backlog is 45% higher than at the start of 2014, the beginning of the current growth cycle. Current year spending from starting backlog has increased every year and in 2017 it will be up 35% over 2014. About 75% to 80% of all nonresidential buildings construction spending in 2017 will be generated by projects that are already underway (in backlog). Only 20% to 25% of all spending in 2017 will come from new projects that start in 2017.
New construction starts in the final three months of 2016, although well below the yearly highs reached in August and September, helped carry 2016 new starts to an eight-year high. Nonresidential Buildings starts for the last six months averaged the highest since the 1st half of 2008.
Jobs growth may look quite slow this year.
Jobs growth over time follows closely to volume growth, not spending growth. Real volume growth is spending minus inflation. I’m predicting 6% spending growth in 2017, but after inflation that represents less than 2% volume growth. Therefore, we may add less than 2% new jobs in 2017, or less than 140,000 new jobs. An imbalance in growth between jobs and volume does sometimes occur. In the last 25 years that annual imbalance, whether up or down, has exceeded 3% only six times. Those six years were all either construction boom years or recessions. For all the other years, the difference in growth between jobs and volume has averaged less than 1%. Whether we look at the last four-year period or the last eight-year period, jobs and volume growth have been within 2%.
The attached plot shows actual and predicted construction spending compared to several industry leading indicators. The ABI, produced by the American Institute of Architects (AIA) shows work on the boards at architectural firms. Values above 50 indicate work increasing, values below 50 = work decreasing. The DMI is a survey from Dodge that gives an indication of new construction momentum. Starts is the total cash flow growth from all nonresidential starts currently in backlog.
Both the ABI and the DMI have long lead times. For example, the ABI value posted by AIA today is an indication of what to expect 9 months from now. I’ve plotted the values for ABI and DMI out at the lead time dates (# of months) in the future so they would correspond to future cash flows from all starts and predicted spending. The Starts, DMI and Spending values on this plot are indexed so they could be plotted with the ABI while keeping growth trends in each index true.
- ABI – Architectural Billings Index
- DMI – Dodge Momentum Index
- Starts – Aggregate Cashflows of Dodge Starts
- Spending – Actual and Predicted Construction Spending
Overall Spending mostly correlates with Starts except that Starts showed a steeper growth rate in 2016 before a drop. Starts and Spending match well for all of 2014 and 2015. Both DMI and ABI are more erratic, however, the advances and declines in the ABI do correspond well with pickups and slowdowns in Spending. From mid-2015 through the end of 2016, the DMI was in a narrow range and that could possibly be said to be in synch with a slowed period of Spending.
Although they don’t match exactly by month, the ABI, DMI and Starts all show a drop sometime between 4th qtr 2016 and 2nd qtr 2017. That appears in Spending as a slight dip in 1st qtr 2017. The ABI gives an indication of a nice increase midyear. Both DMI and Starts are indicating substantial growth in spending by year end 2017.
