New construction starts in March increased 5% to a seasonally adjusted annual rate of $743.7 billion, marking the third straight monthly gain, according to Dodge Data & Analytics.

The total construction growth in March was led by the nonbuilding sector, and particularly by public works, which featured the start of two large pipeline projects—the $4.2-billion Rover natural gas pipeline in Ohio and Michigan, and the $2.5-billion Mariner East 2 propane and natural gas liquids pipeline in Pennsylvania.

3月份的住宅大楼注册了温和的增长，在柔和的2月份后，多户住房的反弹有助于。3月份的非住宅建筑以2月的速度保持稳定，因为办公楼和机场航站楼的强大活动抵消了制造厂的急剧下降。

Through the first three months of 2017, total construction starts on an unadjusted basis were $160.1 billion, down 3% from the same period a year ago (which included heightened activity for manufacturing plants and electric utilities/gas plants).
如果排除了经常挥发性的制造工厂和电力汽车类别类别，则在2017年的前三个月中，总建筑业的总构建时间将比去年增长8％。

The March data produced a reading of 157 for the Dodge Index (2000=100), compared to 149 in February and 147 in January. After sliding to a weak 129 in December, the Dodge Index over the next three months bounced back 22%. On a quarterly basis, the Dodge Index averaged 151 during this year’s January-March period, up 9% compared to the 139 average for the fourth quarter of 2016.

“The pattern for construction starts in early 2017, with three straight monthly gains, is the reverse of the three straight monthly declines that closed out 2016,” said Robert A. Murray, chief economist for Dodge Data & Analytics.

“While the construction start statistics will frequently show an up-and-down pattern, whether month-to-month or quarter-to-quarter, the improved activity in this year’s first quarter provides evidence that the construction expansion is still proceeding,” Murray added.

“This year’s first quarter has seen nonresidential building and public works rebound from the loss of momentum each experienced towards the end of 2016, helped respectively by the strong activity so far in 2017 for new airport terminal projects and new pipeline projects.

2017年“非住宅建筑应该可以stay on its upward track, supported by further growth for such institutional project types as school construction. As for public works, it’s also expected to show improvement over the course of 2017, although its prospects are less certain given its connection to legislative developments at the federal level.

“This includes how Congress will deal with the continuing resolution for fiscal 2017 appropriations scheduled to expire at the end of April, and whether a new federal infrastructure program will get passed this year,” Murray said.
