A sinkhole discovered in December 2018 caused an additional charge for an agriculture building and greenhouse project underway at Ozarks Technical Community College’s Richwood Valley campus.

Mark Miller, director of communications and marketing for OTC, said the $7,906 charge — disclosed Monday during an OTC Board of Trustees meeting — will not delay the $2.1 million project’s expected completion in August.

“This was covered in the contingency, and the board approved the change,” he said via email.

After Christmas, project general contractor Crossland Construction Co. Inc. discovered a foot-wide sinkhole after heavy rains, Miller said. Contractors excavated the hole out to 11 feet, determining it was 5 feet wide and 9.5 feet deep.

“The contractor mitigated the opening by filling it in, installing rebar into the bedrock and pouring a concrete slab on top, and backfilling over the concrete,” he said.

The sinkhole was first reported by the Springfield News-Leader.

At OTC’s Christian County campus in Ozark and Nixa, crews are working on a 7,680-square-foot agriculture building, which will have classrooms, labs, offices and equipment, as well as a 2,350-square-foot greenhouse, according to past Springfield Business Journal reporting. Paragon Architecture LLC designed the project.
