Founded in 2017 by father-and-son team Robert Timberman and Robert Timberman Jr., Black Diamond General Contractors is a full-service earth work and site work company based in the Charleston Peninsula of South Carolina. They do a bit of everything — from groundwork, infrastructure work, water, sewer city work, city repairs — they even have a vertical construction division.

“We do a lot of public utilities, site development, and we do some vertical construction, mostly in residential. We do commercial as well,” says Robert Jr. “Essentially, what we are is a one-stop shop. We’ll get a site that’s completely wooded. We’ll clear it, develop it, install the stormwater, water mains, sewer mains, and the public utilities and hand over a finished product ready for vertical construction.”
