Local Concrete Flatwork Specifications Webinar
April 16, 2013
About the Event
This webinar reviewed the Minnesota Concrete Flatwork Specifications guide developed by the Minnesota LRRB and Minnesota LTAP. The document provides specs for local agencies and the concrete industry to follow as they move through the life of a local concrete project. It is intended to be used separately from the MnDOT specifications, except for the use of the existing approval process developed and maintained at MnDOT for any products and certifications.
This document allows contractors more control over mix design and construction inspection quality control—items such as joint layout will become the responsibility of the contractor. Acceptance of the concrete will be based on concrete strength from concrete cylinders built on the job site. This specification will allow, at the engineer’s choice, the option to use bridge quality aggregates, concrete smoothness, and maturity testing for concrete strength.
Who Should Attend
Engineers and technicians involved in the design or construction of any concrete flatwork, including sidewalks, curb and gutter, driveways, and concrete pavements for local agencies in Minnesota.
