The Dodge Momentum Index dipped slightly in March, falling 2.1 percent to 122.3 from February’s 124.9, according to Dodge Data & Analytics.

The Momentum Index is a monthly measure of the first (or initial) report for nonresidential building projects in planning.

Despite the March decline, the index has trended upward over the last 12 months. For the first three months of this year, it averaged 122.5, a 12-percent gain over the first three months of 2014. This rising trend points to increased construction starts through at least early 2016, according to Dodge.

Planning activity in both the commercial and institutional sectors fell in March, with declines of 1.9 and 2.4 percent, respectively. There were 10 projects valued at $100 million or more that entered planning during the latest month, comprised of seven commercial projects and three institutional projects. The $400 million Five South Development project in Bismarck, N.D., led the commercial sector, while the $250 million first phase of the Children’s Hospital of New Orleans led the institutional segment.
