The two largest components of Public Construction Spending, by far, are Highway/Bridge/Street and Educational Buildings. These two markets have more impact on the magnitude of public spending than any other markets. All of Highway ($90bil) is public spending. About 80% ($70bil out of $88bil) of Educational buildings is public spending. Together they add up to 55% of all public construction spending.
The next three largest public markets in order are: 70% of Transportation ($30/$42bil); all of Sewage/Wastewater ($22bil) and all of Water Supply ($12bil). These three markets account for only about 22% of public spending. Eight remaining markets, none larger than 3.5% of the total public sector, combined make up ~20% of total public spending. Five of those eight, Office, Health care, Public Safety, Amusement and Power, each account for $8 to $10bil and each is 3% to 3.5% of Public work.
Public Construction Spending average for the first six months of 2016 was the highest since 2010 and is up 10% from the Q4’13-Q1’14 low point.
Public spending finished 2016 down 0.8% from 2015, but that is down from a near six-year high, so spending is still strong. It is still -9% below its 2009 peak.
The biggest mover to total public spending this year is educational spending. Public educational spending in 2016 is up 4.7%. Because it represents 25% of all public spending, it has a net impact of moving total public spending up +1.2%, greater impact than any other market.
Public commercial spending is up 24% but has only a 1% market share of public work so moves public spending by only +0.24%. Power is down -20% but at a share of only 3% moves public spending by only -0.6%. Public components of office, public safety, sewage/waste disposal and water supply are all down by a combined -7%. At a combined market share of 18% that nets a -1.26% reduction in total public spending.
Public spending peaked in 2009 when Educational buildings spending was at its highest. Highway spending has been at or near its peak for the last 16 months but that, with current educational spending, which is still more than 20% below its peak, has not been enough to carry public spending to new highs.
Expected spending predicted from new construction starts gives a much better picture for 2017.
Highway/Bridge/Street starts in 2015 finished just shy of a 6-year high (in 2013) but 2016 was down 13% from 2015. On average 2015+2016 starts are still 5% higher than 2014. Highway projects are long duration, so very good starts from the end of 2014 and the beginning of 2015 will still contribute strong spending well into 2017. Highway spending is expected to finish up slightly over 2016.
Educational new starts in 2016 finished the year up 11%, posting a 4th consecutive annual increase and educational spending for 2017 should finish up 10%.
Transportation spending in 2017 should increase 6%.
Overall, total public construction spending in 2017 is predicted to grow by 8% to 9%, the first substantial growth since 2007, reaching new highs in the 2nd half. Educational spending will take the lead in 2017 public work. Historically, public spending increases by less than 10% per year.
