Do I need a structural engineer to knock down a wall?

• <div><p>In many areas, advice from a structural engineer or an architect will be required by your building department before you can remove a wall, but even if it’s not necessary, it’s a good idea. Accidentally removing a load-bearing wall—even if a general contractor advises that it’s safe—can cause major structural damage, putting you and your family at risk and potentially costing thousands or tens of thousands of dollars in property damage.</p></div>

Q: How long does it take for water to cause structural damage?

• <div><p>Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they&rsquo;ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.</p></div>

Q: How do I know if cracks are structural?

• <div><p>The best way to determine if ceiling cracks are structural is to hire a ceiling contractor to inspect the cracks and provide a professional opinion. That said, you might be able to make an educated guess based on the size and appearance of the crack. Larger cracks, cracks accompanied by sagging or discoloration, and cracks that travel from the ceiling down the walls are all signs of structural issues.</p></div>

Q: Is precast concrete reinforced?

• <div><p>Precast concrete can be reinforced with rebar, wire mesh, or other materials to improve its strength and add stability. Precast concrete for large construction projects is often pre-stressed as well for greater structural strength. Reinforced concrete is durable and strong, making it an ideal choice for many construction projects.</p></div>

Q: What building materials are used in Neoclassical architecture?

• <div><p>Stone, marble, and brick are common building materials of Neoclassical architecture, though you will also find wood flooring and a range of natural stone tiles. Since several home styles fall under Neoclassical architects' umbrella, a range of building materials&mdash;including traditional wood framing&mdash;will make an appearance.</p></div>
