Design and Construction Considerations

Proper design accounts for material strength, load distribution, and thermal expansion. Construction must follow precise measurements to align with structural plans, ensuring the opening integrates seamlessly with surrounding elements. Using reinforced concrete or masonry not only enhances durability but also meets safety standards, minimizing risks of cracking or collapse over time.
