Mainboard-listed CSC Holdings, a homegrown foundation and geotechnical engineering specialist, has posted group revenue of $81.4 million for the quarter ended June 30, 2009 (1Q10), compared to $156.8 million in the same period a year ago (1Q09), as uncertainties in economy resulted in significantly subdued demand for construction services.

Net profit decreased 52.8% to $6.7 million in 1Q10 from $14.2 million in 1Q09.

Despite the dip in revenue, the group says it was able to maintain its gross margin at 18.6% compared to 18.4% in 1Q09.
