Join us August 30 – September 1 in Dallas TX
I will be presenting to the plenary session on Main Conference Day 1, Tuesday August 31 on the following:
The State of Construction Post-Pandemic: Revealing Trends in Demand, Supply & Cost Escalation
• Revealing the economic reality and outlook in terms of construction volume and its impact on jobs and prices
• Identifying key metrics and data sources that will give you a reliable indication of inflation for your market
• Determining the likely impact of an Infrastructure Bill and other major construction investments on market forces
The 6th annual Advancing Preconstruction 2021 conference is North America’s largest gathering of contractors, design firms and clients looking to improve coordination of the design phase. You’ll hear how to align cost, schedule and project specifications to set projects up for success.
From conceptual estimating and winning work to constructability reviews and model-based quantity take-off, you’ll discover the latest technologies and workflows across five educational tracks.
New additions for 2021 include:
- Post-pandemic outlooks with a focus on cost escalation for major markets and bidding strategies
- Deep dives into estimating for specific CSI divisions including earthwork, steel, mechanical and electrical
- Benchmarking ways to conduct design reviews and maintain quality of coordination, including with remote working
- How direct material procurement, prefabrication, IPD and other trends could radically alter preconstruction and reduce costs
update 6-15-21 PPI for May
Post Great Recession, 2011-2020, average nonresidential buildings CONSTRUCTION INFLATION is 3.7%. Residential cost inflation averaged over 5% for the last 8 years.
The 30-year avg inflation rate (including recession) for Nonres Bldgs is 3.5% and for Residential it’s 3.4%.
The 30-year avg inflation rate (EXCLUDING recession years) for Nonres Bldgs is 4% and for Residential it’s 4.75%.
I expect non-residential buildings construction inflation in 2021 to range between 3.2% to 3.5%, with potential to be held lower. Expect residential inflation of 7% to 8% with potential to push slightly higher.
As of March 2021, PPI for materials inputs to construction is up 12% to 14% yoy, measured to last March before the bottom dropped out. The PPI Buildings Cost Index for final cost to owner is up only 2%.
Almost every construction market has a weaker spending outlook in 2021 than in 2020. Approx. 50% of nonres spending in 2021 is generated from 2020 starts.
- Nonres Bldgs starts fell 22% in 2020.
- Nonbuilding starts were down 15%.
- Residential starts were up 6%.
While there are several reasons that construction inflation will increase, downward pressure on spending will temper construction inflation.
as of 6-15-21, May PPI report > Inputs to Nonres Constr YTD21 +13.3%. Final Demand Nonres Constr YTD21 +2.7%. Five solid months of 2021 data shows the Input costs of materials IS NOT being passed along to final cost to owner. This could change, but for now final costs of construction are holding well below input costs.
A look back at Res, Nonres and Nonbldg construction inflation over the last 30 years shows rarely has there been any substantial increase in inflation when construction spending is headed down.
- Nonres Bldgs spending 2020 -2.0%, 2021 -7.7%, 2022 -4.5%
- Nonbuilding spending 2020 +2.8%, 2021 -1.3%, 2022 -3.2%
- Residential spending 2020 +12.2%, 2021 +17%, 2022 +4.8%
Over 30 years, looking at the 3 major sectors, Res, Nonres Bldgs and Nonbldg = 90 pcs of data. 27 out of 90 times spending decreased or stayed flat for the year. Only 3 out of those 27 times when spending was down/flat did inflation come in over 3%. Avg inflation for the 27 down/flat yrs is less than 1%. For those 27 times, only 3 times were PPI Inputs less than 2%.
An estimator must differentiate between “added quality” and inflation. Added components or increased level of finish are not inflation, but are picked up in the estimators increased unit costs. Inflation captures higher labor, mtrl, margin costs for same level of build out.
Granite counters and Italian tile floors vs PLam counters and vinyl floor coverings is an increase in quality, not inflation. Increased SqFt is an increase in quantity, not inflation.
7-21-21 June PPI data will probably drive up inflation cost in this report. SEE PPI as of June-July 2021
The report attached below, written in May, suggests inflation that has been changing rapidly. Please read the most recent posts on inflation and the PPI for materials and final costs for updated information.

8-15-21 update – These links at top here point to most recent inflation data, to supplement this post. The latest construction spending forecast reflects inflation of 4% to 5% for nonresidential and 11% for residential. The latest tables and BCI plot, as of 8-15-21, are at the very bottom in this file. All 2021 indices have increased since my May 2021 Inflation Report. These tables have the latest.

Construction Spending 2021 Update 8-2-21 see the section on Jobs vs volume.
Inflation – PPI data June-July 2021 some materials up 20%-40% but final cost up only 5%-6%
1-25-21 What impacts should we expect on Construction Inflation in 2021?
In April 2020, and again in June 2020, I recommended adding a minimum 1% to normal long-term construction inflation (nonres longterm inflation = 3.75%), to use 4% to 5% for 2020 nonresidential buildings construction inflation. Some analysts were suggesting we would experience deflation. Deflation is not likely. 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%. In 2020, volume dropped 8% from Feb to May and we’ve gained half that back by Dec. Jobs dropped 14%, 1,000,000+ jobs, in two months! Now volume is still down 4% and jobs are down 2% from Feb peak. We’ve gained back 850,000 jobs. But also, we’ve gained back more jobs then volume. That adds to inflation.
Volume drops another 5% in 2021, all nonresidential, and then another 3% in 2022. Jobs could drop overall 8%-10% for all of 2021-2022, 500,000 to 700,000 jobs.
Even though material input costs are up for 2020, nonresidential inflation in 2020 remained low, probably influenced by a reduction in margins due to the decline in new construction starts (-24%), which is a decline in new work to bid on.
Volume = spending minus inflation.
Residential business volume dropped 12% from the January 2020 peak to the May bottom, but has since recovered 22% and now stands at a post Great Recession high, 10% above one year ago. Although residential spending remains near this high level for the next year, volume after inflation begins to drop by midyear. For the year 2020, Residential Building Materials Inputs are up 6.2%. See PPI charts. Sharply higher lumber prices have added more than $17,000 to the price of an average new single-family home since mid-April ($24,000 as of 3-30-21). Residential inflation averaged 5.1% for 2020. (UPDATE 3-30-21 – Single Family home prices increased 11% since March 2020. Lumber cost is now 3x what it was in March 2020. These will both impact cost to build SFH).
The U.S. Census Single-Family house Construction Index is up 6% from Nov 2019 to Nov 2020. The index increased 4% in the last 5 months. The index is increasing, now thru February 2021 is up 6.7% for the last 12 months. https://www.census.gov/construction/nrs/pdf/price_uc.pdf
Nonresidential volume has been slowly declining and is now down 10% from one year ago. By 3rd quarter 2021, nonresidential buildings volume is forecast down another 15% lower than December 2020, or 25% below the Feb 2020 peak. This tracks right in line with the 24% decline in new construction starts in 2020. Most of the spending from those lost starts would have taken place in 2021, now showing up as a major decline in spending and work volume. Nonresidential inflation for 2020 dropped to 2.5%, the first time in 7 years below 4%. It’s expected to increase in 2021.
The Producer Price Index tables published by AGC for year-end 2020 https://www.agc.org/sites/default/files/PPI%20Tables%20202012.pdf shows input costs to nonresidential buildings up about 3.5% to 4.5% for 2020, but final costs of contractors and buildings up only 1% to 2%. This could be an indication that, although input costs are up, final costs are depressed due to lower margins, a result of fewer projects to bid on creating a tighter new work available environment which generally leads to a more competitive bidding environment. This could reverse in 2021 as the volume of work to bid on in most markets begins to increase.
As of March 2021, PPI for materials inputs to construction is up 12% to 14% yoy, measured to last March before the bottom dropped out. The PPI Buildings Cost Index for final cost to owner is up only 2%. Construction inflation is very different right now for subcontractors vs general contractor/CM. https://www.agc.org/learn/construction-data
The Turner Construction Cost Index (nonresidential buildings) for Q1-Q2-Q3 is +1%, -1%, -0.5%, effectively reporting the index down -0.5% year-to-date. But the Turner index year-to-date average (avg Q1+Q2+Q3=1179) is still 2.6% higher than the average of Q1+Q2+Q3 2019 and 2% higher than the avg for all of 2019 (1156). So, while the index appears to show no gains in 2020, through the first nine months of 2020 it is up 2.6% above the average of the same months in the 2019 index. http://turnerconstruction.com/cost-index
The Rider Levitt Bucknall nonresidential buildings index average index for 2020 (through October 1, 2020), although up less than 1% in the last 6 months, is up 3.5% from the average 2019 index. https://s28259.pcdn.co/wp-content/uploads/2020/07/Q2-2020-QCR.pdf or try https://www.rlb.com/americas/
R.S.Means quarterly cost index of some materials for the 4th quarter 2020 compared to Q1: Ready-Mix Concrete -1.8%, Brick +10%, Steel Items -1% to -5%, Framing Lumber +32%, Plywood +8%, Roof Membrane +5%, Insulating Glass +12%, Drywall +3%, Metal Studs +23%, Plumbing Pipe and Fixtures +1%, Sheet Metal +20%. 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: Cement, steel, doors, frames, 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. Scrap steel prices are up 27% in the last quarter and up 40% for the year 2020. Scrap is the #1 ingredient for new structural steel. The U.S. steel industry experienced 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% in January 2020 to 56% in April. In mid-August, CapU was up to 61%, still very low. As of January 23, 2021 CapU is up to 76%, well above April’s 56% but still below desired level. Steel manufacturing output is still down compared to pre-covid levels. Until production ramps back up to previous levels there may be shortages or longer lead times for delivery of steel products. In August 2021, CapU is back to 85%.
Steel Prices at mill in the U.S. are up 60% to 100% in the last 6 months. All prices are 50% to 75% higher than Feb 2020. http://steelbenchmarker.com/files/history.pdf . This is mill price of steel which is about 25% of the price of steel installed. What affect might a steel cost increase have on a building project? It will affect the cost of structural shapes, steel joists, reinforcing steel, metal deck, stairs and rails, metal panels, metal ceilings, wall studs, door frames, canopies, steel duct, steel pipe and conduit, pumps, cabinets and furniture, and I’m sure more. Assuming a typical structural steel building with some metal panel exterior, steel pan stairs, metal deck floors, steel doors and frames and steel studs in walls, then all steel material installed represents about 14% to 16% of total building cost. Structural Steel only, installed, is about 9% to 10% of total building cost, but applies to only 60% market share being steel buildings. The other 6% of total steel cost applies to all buildings. https://www.thefabricator.com/thefabricator/blog/metalsmaterials/steel-prices-reach-levels-not-seen-since-2008 At these prices, if fully passed down to the owner, this adds about 1.5%-2% to building cost inflation. With demand in decline for nonresidential buildings, I would expect to see all these steel price increases recede. Also, take note, as of January 2021, none of this steel price movement appears captured in the PPI data or RSMeans data.
Contractors have been saying they have difficulty acquiring the skilled labor they need. This has led to increased labor cost to secure needed skills. I expect the decline in nonresidential work volume in 2021 to result in as much as a decline of 250,000 nonresidential jobs in 2021. This results in labor available to fill other positions.
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 would equate 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. But that may not remain constant over the entire duration of the project, so the net effect on project cost would be less.
Post Great Recession, 2011-2020, average nonresidential buildings inflation is 3.7%. In 2020 it dropped to 2.5%, but for the six years 2014-2019 it averaged 4.4%. Residential cost inflation for 2020 reached 5.1%. It has averaged over 5% for the last 8 years. The 30-year average inflation rate for nonresidential buildings is 3.75% and for residential it’s over 4%.
This survey of members by AGC https://www.agc.org/sites/default/files/2021_Outlook_National_1221_.pdf just published provides some insight into construction firms outlook for 2021.
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 nonresidential starts are down 10% to 25%, several markets down 40%. Nonbuilding starts are down 15%, but will increase 10% in 2021.
Typically, when work volume decreases, the bidding environment gets more competitive. We can always expect some margin decline when there are fewer nonresidential projects to bid on, which typically results in sharper pencils. However, if materials shortages develop or productivity declines, that could cause inflation to increase. We can also expect cost increases due to material prices, labor cost, lost productivity, project time extensions or potential overtime to meet a fixed end-date.

Constant $ = Spending minus inflation = Volume
Many projects under construction had been halted for some period of time and many 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, not only does labor cost go up but also management cost goes up, or it could add overtime costs to meet a fixed end-date. Some of these project costs have yet to occur as most would be expected to add onto the end of the project.
Some projects that were put on hold (nonresidential buildings starts in 2020 dropped 24%) just prior to bidding in 2020 may now re-enter the bidding environment. The rate at which these projects come back on-line could impact the bidding environment. If several months worth of projects that delayed bidding last year all come onto the market at once, or at least all in a more compressed time span than they would have, the market could be flooded with work and bidding contractors now have more choice, can bid more projects than normal and could potentially raise margins in some bids. This would have an inflationary effect. Also, there can be difficulty in starting many projects at the same time, rather than more staggered starts. It burdens subcontractors and suppliers with too much of the same type of work all going on at the same time. This could exacerbate labor issues and could lead to project time extensions.
The hidden inflationary costs of bidding environment, project time extensions, potential overtime and lost productivity haven’t all yet appeared in the data. Some of these could still add to 2020 inflation. Also, the huge loss of new starts in 2020, which meant fewer projects to bid on in 2020, probably reduced margins in 2020. Nonresidential starts are projected to increase 4% in 2021, so that could lead to some recovery of margins, however, even with 4% growth in new starts, that comes after a 24% drop in 2020, so remains still 20% below 2019. Total volume of work is declining and new projects available out to bid is still depressed, so pressure on margins still exists.
update 4-15-21 Although materials cost inflation will be higher, I expect non-residential buildings inflation final cost in 2021 to range between 3.5% to 4.0%, with potential to be held lower. Subcontractor costs, such as for steel or lumber, could range much higher due to huge material cost increases. All the downward pressure on nonresidential inflation is on margins. There is currently 20% less nonres bldgs work to bid on than in Q1 2020.
updated 3-30-21 Expect 2021 residential inflation of 6% to 8% with potential to push slightly higher.
See Construction Inflation Index Tables for indices related to Nonbuilding Infrastructure work and for more links to sources.
(8-15-21 The tables and plot below include updated residential costs and updated nonresidential inputs).
The tables below, from 2011 to 2020 and from 2015 thru 2023, updates 2020 data and includes Q2 PPI data thru June and provides 2021-2023 forecast. The three sectors, highlighted, are plotted above.
NOTE, these tables are based on 2019=100.
Nonresidential inflation, after hitting 5% in 2018 and 4.8% in 2019, and after holding above 4% for the six years 2014-2019, ended 2020 at 2.4%. Current forecast is 4.3% for 2021 and holds near 3.75% the next few years. The volume of work is constrained thru mid 2022 and this could hold inflation in check.
Forecast residential inflation for 2021 is 11% and for 2022-2023 years is level at 3.8%. It was only 3.4% for 2019 but averaged 5.5%/yr since 2013 and came back to 5.4% in 2020. Recent materials costs and record volume of work could impact residential inflation and push it higher.
The following table shows 2021 updated as of 8-15-21 reflecting 4.3% inflation for nonresidential buildings and 11% for residential.
How to use an index: Indexes are used to adjust costs over time for the affects of inflation. To move cost from some point in time to some other point in time, divide Index for year you want to move to by Index for year you want to move cost from. Example : What is cost inflation for a building with a midpoint in 2022, for a similar nonresidential building whose midpoint of construction was 2016? Divide Index for 2022 by index for 2016 = 110.4/87.0 = 1.27. Cost of building with midpoint in 2016 x 1.27 = cost of same building with midpoint in 2022. Costs should be moved from/to midpoint of construction. Indices posted here are at middle of year and can be interpolated between to get any other point in time.
All forward forecast values, whenever not available, are estimated by Construction Analytics.
Also See Construction Inflation Index Tables the post for links to dozens of other indices
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/
UPDATE 10-14-20 NAHB reports thru September (Residential) Building Materials Up 4.4% in 2020. See PPI charts. Increases for lumber and ready-mix concrete are noted. LUMBER “Over the last five months, the PPI for softwood lumber has nearly doubled (+90.9%). Sharply higher lumber prices have added more than $17,000 to the price of an average new single-family home since mid-April.” CONCRETE “Prices paid for ready-mix concrete (RMC) rose 1.5% in September (seasonally adjusted), a monthly increase the magnitude of which is atypical of the commodity. The national PPI for RMC has increased by more than 1% just five of the 135 months since the end of the Great Recession. The average annual change in prices paid for RMC was 2.6% over the last decade.” https://www.eyeonhousing.org
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.
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.
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.
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.
1-28-20 This original post, Inflation excerpt from the complete economic report – Construction Analytics 2020 Construction Economic Forecast – Jan 2020
8-25-20 See also Pandemic #14 – Impact on Construction Inflation
1-27-21 See 2021 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.
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
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 specific 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.

vs Range of Input 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.
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.
Non-building Infrastructure indices are far more market specific than any other type of index. Link here to Reference specific Infrastructure indices rather than an 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.

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.
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.
This is a partial selection of slides I will be presenting on May 16 in Dallas at Hanson Wade’s Advanced Building Estimation Conference. I’m covering the topics Inflation/Escalation and Forecasting particularly as it relates to staffing planning.
