What Changed in the 2020’s?

Fire Protection & Life Safety Systems Integrated Testing

It’s time to apply lean six sigma’s mistake-proofing approach in fire protection and life safety systems.  The methodology  had a long and successful history in its broad application across different industries — not only in manufacturing and the health systems but in many other fields.

“Integrated Systems Testing” is a new requirement of the Ontario Building Code, in effect since January 1, 2020 for construction new projects in Ontario. Other provincial jurisdictions across Canada have similar requirements.

CloserToLean and our technical partners–leaders in fire protection and life safety systems–are pleased to provide you our services.

Who We Are, Our Purpose

CloserToLean focused from its inception (early 2020) to lean manufacturing and six sigma consulting.

Beginning the second half of 2023, we shift our focus  to fire protection and life safety systems, after attending two presentations of Vitalis Engineering (in April 2021 and April 2023).

Our founder, Vir Alvaran has sat  in the OpEx Society’s international Advisory Board since 2022, after his writings got published in the Operational Excellence Society’s Body of Knowledge, and has been featured in Vir worked for 20 years (in engineering) for North America’s auto parts supply chain, helping improve the quality and field safety of cars, light trucks, and heavier vehicles.

Active for years until early 2023 with the Ontario Society of Professional Engineers (OSPE) and the international association,  Institute of Industrial & Systems Engineers (IISE), Vir now devotes most of his volunteer hours as an executive in the Ontario Association of Certified Engineering Technicians & Technologists (OACETT), which conferred him in 2023 its “Quarter Century Award” for his years of continuous membership and support.

In furtherance of fire protection and life safety, we are pleased to partner with Vitalis Engineering.  The company is a recipient of a  Letter of Congratulations from Markham-Unionville MPP Billy Pang on the occasion of its grand opening in 2021, “to provide excellent engineering consultation experiences to clients and create jobs locally.”

As a local Fire Protection and Life Safety Engineering service provider, Vitalis (with CloserToLean, as agent or partner) is happy to provide quality Engineering consultation services to local building owners, developers and managers.
