2018 CONSTRUCTION AND MATERIAL SPECIFICATIONS

UTILITY CONTRACTORS, DEVELOPERS, DESIGN & CONSULTANTS

The City of Columbus recently completed an update to its Construction and Materials Specifications (CMSC), which are in effect as of March 1, 2018.

For CIPs:
Any contract previously awarded will continue to follow the 2012 CMSC unless otherwise directed by the department. In addition, construction contracts will specifically state which version of the CMSC the contractor is to follow.

For private development projects:
Any project with previously approved site plans may still follow the 2012 CMSC unless otherwise directed by the department. Any new projects that are submitted for review must conform to the 2018 CMSC. The 2018 CMSC is available online through the Department of Public Service's website:
