Backlog Construction Forecast Fall 2017


Total Construction Starting Backlog is at a record high, up 30% from the previous high in 2008.

Infrastructure and Residential sectors dropped to a decade low backlog in 2010. In 2013, nonresidential buildings hit the lowest starting backlog since 2004. Combined, total backlog hit a low-point in 2011, the lowest since 2003. Total Starting Backlog has been increasing since 2011, up 65% in 2018.

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. Residential backlog is at a post-recession high, although as will be explained later, it is new residential starts that are more important and starts have tripled since the 2009 low. 70% of all residential spending in the year comes from new starts. Residential starts are still 20% below the 2004 peak.

Starts Generate Backlog

New Starts increased at an average rate of 11%/year from 2012 to 2016. 2017 starts slowed to less than half that pace.

Nonresidential Buildings starts, even though there was a 1% decline in 2015, averaged 13%/year growth for the last 4 years. 2017 will post an 8% increase. The 6 months from Aug 2016 to Jan 2017 was the highest starts since Jan-Jun 2008, also the year nonresidential buildings spending peaked. The 6 months Apr-Sep 2017 just surpassed both those previous peak highs.

Non-building Infrastructure starts were the highest in the 1st 6 months of 2015 than any 6-month period in history. Total 2015 starts increased 26%. 2016 is down just 2% from the peak 2015 starts and 2016 is the 2nd highest starts on record. Those early 2015 starts will still generate 10% of all spending in 2018. 2017 starts are level with 2016. After revisions, 2017 starts may set a new peak high.

Residential starts in 2016 posted the best year since 2005-2006. New starts in 2016 were revised up to show an increase of 10% over 2015. That follows five years of growth averaging 20%/year. New starts in Q1’17 reached an 11 year high.

Entering Backlog

New Backlog is added every month from New Construction Starts. When projects first enter backlog, the amount counted to backlog is the total value of project revenues under contract that are about to start construction, or the same as the new start values. For purposes of predicting future construction spending, as each month of project construction passes, work that has been put-in-place is subtracted from the total value to get the amount remaining in backlog.

Starting Backlog

Starting Backlog is the Estimate-to-Complete (ETC) value of all projects under contract at the beginning of a period. Projects in starting backlog could have started last month or last year or three years ago. The amount counted in backlog is the value of the project that remains or that has not yet been put-in-place. Backlog is the total amount of future spending that will be generated by the project, commonly referred to as the ETC. The sum of all ETCs represents current backlog.

  • Nonresidential buildings 2018 starting backlog is up 10%
  • Non-building Infrastructure 2018 starting backlog is up 12%
  • Residential buildings 2018 starting backlog is down 3%
  • Starting Backlog is at an all-time high for nonresidential buildings and non-building infrastructure.

Typically, starting backlog is a reference to the amount of work in backlog on January 1st. It is referred to as the Starting Backlog for the coming year. The sum of all ETCs as of December 31st represents Starting Backlog.

For any project that has a remaining duration going out past year end, backlog at the start of year does not represent the amount that will be spent within the year. Some of that project backlog will be spent in future years. For this reason, backlog is not representative of spending within the year and the change in Starting Backlog from year to year is not an indication of a change in spending from year to year.

Values and duration of projects that make up backlog help to better predict spending activity over time, particularly in the coming year.

A cash flow schedule of all ETC backlog and predicted new starts provides a tool to predict future spending. It is not enough to look at just the change in backlog to get an indication of the strength of the market. While continued growth in backlog is important, the predicted cash flow from backlog and cash flow from new starts is necessary for predicting spending.

Construction spending is strongly influenced by long duration projects in backlog, more-so than normal monthly starts growth rate. The pattern of continuing or ending cash flows from the long duration backlog projects causes fluctuations in spending that supersede the balance cycle of one month of old jobs ending for every new month of jobs starting. This often can be responsible for some of the monthly fluctuations of construction spending.

The following table shows predicted cash flow from backlog on record as of October 1, 2017 and predicted starts that will generate future backlog in 2018.

Look Ahead to 2018

Buildings and Infrastructure will both hit new all-time highs for starting backlog in 2018.  For four years, from 2010 to 2013, all nonresidential backlog remained nearly constant. Since then, growth has been similar to the pre-recession construction boom of the early 2000s.

Nonresidential buildings 2018 starting backlog is 50% higher than at the start of 2014, the beginning of the current growth cycle. Starting backlog has increased for 5 years at an average 10%/year. Spending from starting backlog, up 10% in 2018, increased for 5 years at an average 9%/year. Buildings will reach a new high for spending in 2018.

Non-building Infrastructure 2018 starting backlog is up 35% since 2014 but spending from backlog is up only 10%. Infrastructure starting backlog has been increasing for more than 10 years, sometimes only a fraction of a percent per year. Since 2010, backlog increased only 3%/year for the first 5 years then it jumped 35% in the last 3 years. Spending within the year from starting backlog is up 8% in 2018. Infrastructure spending will hit a new high in 2018.

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 residential spending within the year. New residential starts in Q1’17 reached an 11 year high.

  • Cash flow models of construction projects in backlog are indicating substantial acceleration in nonresidential spending over next year, perhaps most notable in infrastructure.
  • 75% to 80% of nonresidential spending within the year comes from Starting Backlog.
  • 70% of residential spending within the years comes from New Starts. Residential starts are at a post-recession high.
  • Share of spending within the current year from backlog is at an all-time high for nonresidential buildings and non-building infrastructure.

Nonresidential Buildings

Nonresidential buildings experienced a decline in starting backlog as recently as 2013. Since 2013, nonresidential buildings starting backlog is up 60%. Backlog will hit a new all-time high for 2018, 5% over the previous high in 2009 . Not only is starting backlog higher coming into 2018, but also spending from backlog is predicted up by 10%. This will produce a new high in current dollar spending.

Revenues from starting backlog account for 75% of all nonresidential buildings construction spending within the year.

Educational starts, backlog and spending has been increasing for 5 years or longer. 2018 starting backlog is up 16% from 2017. Starts for 2018 are predicted to go up 13% and this will push 2019 starting backlog even higher. This should produce good spending growth for the next few years.

Office construction starting backlog for 2017 was the highest in at least 8 years, more than double at the start of 2014 when the current growth cycle of office construction spending began. For 2018 it’s up 27% over 2017. Office starting backlog increased an average of 28%/year for the last 5 years. Actual spending increased an average of 17%/year. Backlog growth looks like it will support very strong spending increases into 2019.

Commercial Retail backlog will hold steady from 2017 into 2018. This should level off spending after 7 years of strong growth. 2018 backlog still produces a spending increase but current projections show a slight drop in 2019.

Lodging backlog increases slightly for 2018. Beyond 2018, spending will decline, but this is after 6 years of growth totaling 300%.

Manufacturing posted a 100% increase in new starts in 2014 that drove starting backlog to new highs for the next two years. With new starts slowing back to normal by 2016, starting backlog dropped 20% in 2017 and spending dropped 12%. That was expected. What was unexpected is that 2017 posted another very strong year of new starts and that pushed 2018 starting backlog again to a new high. This will support a spending rebound in 2018-2019 after a drop of 18% in the last two years.

Non-building Infrastructure

Non-building infrastructure backlog stood at $180 billion in 2008, the last pre-recession year. At the beginning of 2017, non- building infrastructure backlog hit an all-time high, $260 billion, up 45% from 2008. For the last three years, starting backlog is up 40%. In 2018, it’s up 13%, another new high.

Revenues from starting backlog account for 80% of all non-building infrastructure construction spending within the year.

Power backlog has doubled since 2014. It’s up 11% for 2018. Starts are down 14% from the 2015 peak, but spending from backlog is increasing. Most relevant is that backlog increased much stronger than spending. Backlog is being driven higher by very long duration projects that started in 2015, 2016 and 2017.

Highway starts declined the last two years from the peak in 2015, but starting backlog increased the last 3 years and is now 25% higher than 2015.  The last three years of highway starts are still feeding spending in 2018. There is very little change in the amount of spending from backlog, so 2018 spending won’t change very much from 2017.

Transportation new starts shot up by 70% in 2017, pushing 2018 starting backlog to a new high, up 75% from 2017. That will help increase 2018 spending by more than 15%, but a larger spending increase could come in 2019.

Environmental Public Works, Sewer/water/Conservation is experiencing declining starts, declining backlog and declining spending from backlog. All are at the lowest since 2014. We may not see any increase in construction spending until 2019.

Public Work

Public vs Private starts are not tracked separately, but the public share of markets is known. Therefore a projection of public backlog is possible. Highway and Environmental Public Works are 100% public.  Educational is 80% public, Transportation is 70%, Amusement/Rec is 50%, Healthcare is 20% and Power is 10% public, along with few other smaller shares. Starting backlog for 2018 is up 40% from 2014 due to the predominantly long duration projects that make up public work. This is a post-recession high and is nearing the all-time high of 2008. Increased backlog is indicating the best construction spending increases since 2008 for the next two years.

Residential Buildings

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 now 3x higher than the lows. New residential starts have increased every year since the 2009 bottom, but are still 25% lower than 2004-2005. Residential spending reached its peak of $630 billion in 2005. Current spending is still 15% below that peak. In constant $, spending is 30% below that peak.

Due to the shorter duration of projects, nearly 70% of residential spending within the year is generated from new starts. Unlike longer duration nonresidential projects, 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 residential construction industry.

New starts slowed in 2017 to only 4% growth and similar growth of 6% is expected for 2018. This is not unexpected after 5 years (2012-2016) of new starts growth at an average 20%/year. This leads to a prediction of 2018 spending up only 6%.
