I hired contractors to install a large basement window, but they strayed from the engineer's plans. Instead of using epoxy anchors to secure the metal bracing to the concrete wall, they opted for compression anchors. Furthermore, the angle above the window on the exterior ended up being 2 inches too short on both sides. To address this, they added an extra bracket inside to support it. We experience extreme temperature fluctuations (-30°C to +15°C in the same week) where we live. I'm worried about potential long-term issues due to these changes. Do you think I should inform the engineer about these deviations? What could be the consequences, like needing new plans or permits? We just want to make sure our house is safe and not compromised. What would you do in this situation? Thanks in advance!

Just to clarify, what's a compression anchor? Is it similar to a wedge anchor? Also, where exactly did they install it in relation to the wall?
Yes, definitely tell the engineer! They need to assess the changes either with photos or by visiting the site. They'll likely want to discuss it with the contractors too. This is the only way you'll get a solid answer about whether the work complies with safety standards, especially with the temperature extremes you face.
Thanks for the quick response! I agree, even if it might create more trouble, it's better to know now than regret it later.
