Throughout the year a number of firms provide predictions of various construction data.  Some firms provide estimates for all segments of construction.  More firms provide estimates only for spending on nonresidential buildings.  This is a summary of various firms estimates published in the 2nd quarter and also for those who’ve updated their estimate recently.

The current available spending data through August allows an analysis of a select data set that gives a prediction of the year end result within +/- 1.5%. My current data predicts 2015 will finish with nonresidential spending at $393 billion, with a potential range between $387 billion and $400 billion. We will have even better data on November 2nd when the US Census publishes construction spending for the month of September. Once the September data is incorporated into the monthly totals, an analysis of a select data set provides a prediction of the year-end totals that has not varied more than +/- 1% from the end-of-year actual since 2002, as far back as the market data is available.
