Concrete is a key material in foundations, slabs, and structural elements. In Ontario’s climate—with frequent freeze–thaw cycles and rapid temperature changes—verifying concrete quality is essential to ensure long-term performance. Concrete testing methods confirm that both fresh and hardened concrete meet required strength, durability, and code standards under OBC and CSA A23.1/A23.2. Why Concrete Testing Matters Even small variations in mix proportions, temperature, or pl

Bolted steel connections play a central role in how structures behave under load—from everyday gravity forces to wind, vibration, and seismic activity. In Ontario’s industrial and commercial sectors, the choice between Bearing-Type  and Slip-Critical  connections is not just a detailing preference; it directly impacts structural performance, installation costs, and long-term durability. While both systems are accepted under CSA S16 (Design of Steel Structures) , they functi

A Pre-Start Health and Safety Review (PSR) is an engineering review required under Ontario’s Occupational Health and Safety Act (OHSA), Regulation 851. It ensures that new or modified structures, racking systems, and industrial setups are safe, compliant, and structurally sound before use. In simple terms, a PSR is a proactive engineering process that confirms everything is designed and built to perform safely before the system is put into service. When Is a PSR Required? A P
