Big moment for Rapid City; dedicated Fire Station #1. We helped with Civil Engineering and Landscape Architecture with Chamberlain Architects. Special recognition for Tom Poland, Superintendent for MAC Construction! He got a totally cool helmet to remember the project…

Big news! Terrasite Design has been acquired by Interstate Engineering. We are now the Rapid City office. Same team, same people, same creative, innovative services. Bigger group, better resources, larger presence.

TerraSite was honored to be the Civil Engineers and Landscape Architects for this amazing expansion project led by Chamberlin Architects for the Rapid City Municipal Government. MAC Construction was the general contractor and did a great job bringing this design to reality!

Another project coming to a close! A new musical playground for all to enjoy at the Rapid City Public Library and a nice display of native plants that will educate people on sustainable plants that are adaptable to our environment. Thank you to SECO Construction, Inc., SYNLawn Mountain West South Dakota, and Key City Landscapes for your outstanding work!
