Economists had forecast a 0.7% decline, Bloomberg reported.
Private residential construction plunged 4.6%, the biggest drop since comparable records began being kept in 1993, Bloomberg said.
Non-residential construction, including public projects, rose 1.3%, though it was up 12% from a year earlier. Ìý Construction spending can boost demand for trucking services because spending increases the number of shipments of goods and building materials.
