Production Facilities Certification



In conjunction with consultants, the Ministry of Transportation of Ontario (MTO) and the Ontario Provincial Standards and Specifications (OPSS), the Concrete Ontario Technical Committee has developed a detailed concrete facility certification process.

How it Works

Concrete Ontario implements this by a production facility audit that is conducted by a qualified independent third party professional engineer in order to ensure that facilities, equipment, materials, material handling, product and delivery/mixer trucks have met the minimum prescribed qualifications and that the proper “capability” of producing quality concrete exists as per Canadian Standards Association A23.1-19 – Concrete Materials and Methods of Concrete Construction, and A23.2-19 – Methods of Test and Standard Practices for Concrete.

Prerequisites for Certification

The Concrete Ontario Facility Certification process consists of two mandatory parts that all members must meet before a plant certificate can be issued.

Part A – Concrete Facility Audit

This portion of the certification process addresses the mandatory certification requirements of the concrete facility, concrete mixing equipment and concrete delivery vehicles.

Part B – ECO Concrete Facility Audit

This portion of the certification process addresses both the mandatory environmental requirements of the Ministry of Environment that relate to concrete facility operation (ECO) and the optional best practice requirements that confirm the concrete producers’ commitment to exceed minimum environmental requirements (ECO Gold).
