Seattle

Construction Cost Index, Q4 2019

Construction Cost Index

(JANUARY 2009 = 100)

Both the Seattle and national construction cost indexes tracked upward in 2019. The national index increased 3.3 percent since year-end 2018 and the Seattle index increased 2.1 percent, but the Seattle index is still four points higher than our national index.

Construction Employment

(an indicator of future wage and activity trends)

Construction employment in the Seattle region grew 4 percent in 2019. Low unemployment in the area will continue to drive a tight labor market. We anticipate modest construction employment gains in 2020.

• Steel Framing & Stair Erection (5.0%)

Note: All other components (14% of the index) increased 0.1%.

While the majority of building components that make up the index saw flat to moderate cost increases in the most recent quarter, two components experienced relatively higher growth and two components declined.

Advice for Building Owners

 

The Seattle construction cost index ended 2019 at an all-time high and is tracking higher than our national index. While we continue to monitor the impact of both geopolitical and economic uncertainty, all signs point to stability for the construction industry in 2020. The Dodge Momentum Index (a leading indicator of future construction activity) increased in December, and there is a strong backlog of work in the market. Construction employment and materials costs should remain steady for the foreseeable future. We recommend owners plan on a 3% to 3.5% increase in 2020.
