Timber-framed construction is probably the oldest and most used type of construction in the world. Concrete is one of the most common building materials. It is a material composed of fine and coarse-grained aggregates mixed with a binder such as cement and water. The mixture is then allowed to cure and harden over time.
Concrete takes seven days to cure and an average of 28 days to achieve maximum strength. Reinforced concrete is more common in construction, where steel is embedded in concrete to increase structural tensile strength. Concrete comes in many forms, with examples such as lightweight concrete and impermeable concrete. The type of project determines the type of concrete used.
One of the most important advantages of concrete is that it can be poured into any shape and hardened into a stone-like material. The construction of skyscrapers arose from our discovery of steel as a reinforcement material. Steel is a composite material made of iron and carbon alloys. Steel has high strength and functionality.
It's also lightweight, easy to work with, and cheaper to ship than other building materials. Steel doesn't easily warp unless we place an enormous amount of weight on it, and it retains its structural properties even when it's bent. Because of its structural stability, we use steel to manufacture the structural structures of tall, modern buildings. Steel has distinctive qualities, such as a high strength to weight ratio.
Its installation takes less time than concrete and we can install it in any environment. However, if not properly installed, steel is susceptible to corrosion. One of the major drawbacks of steel as a construction material is that it is likely to break during high temperature levels. Its level of fire resistance depends on the type of steel.
Arguably, wood is the oldest building material, as it has been used. It's naturally available and cost-effective, strong and durable, and flexible in every way. Can be bent, molded or cured into desired shapes. In addition to its durability, wood is an environmentally sustainable material.
We can use wood for commercial and residential buildings, and it works well with other materials. Works functionally well with steel, marble and aluminum. Compared to other building materials, wood is relatively light and easy to standardize in size. It has a high tensile strength and is good at soundproofing and insulation.
Stone is the most durable building material. The oldest buildings in the world are made of stone. We tend to use stone on walls and floors, and the texture makes it versatile. Stone comes with soft, textured and rough finishes, and it also comes in many different colors.
Some examples of stones used in construction are sandstone, granite and marble. Common stone is cheap, but prices go up for unique finishes. For marble countertops, quality and color increase production time and cost. Its density affects its workability due to its weight, making it difficult to move.
Stone is also a terrible insulator, therefore ineffective for insulation in cold environments. Masonry uses bricks, which are rectangular blocks, and are then joined together with mortar. Bricks were traditionally made from dry, heated clay. They have a high compressive strength, but can break easily.
The most important bricks that exist now are concrete blocks that are reinforced with steel. Because of its high compressive strength, we use it to build load-bearing walls. Masonry can withstand multi-storey buildings when reinforced with concrete, providing an economical construction option. It is fire resistant and does not rot, so it lasts a long time.
The metal most used in construction is steel; however, other metals such as aluminum. Copper, iron and steel are also used for different aspects of construction. The type of project you're working on will often determine the type of contract, the materials, and the specifications required. In ordinary type 3 construction, you will typically find non-combustible materials in structural elements, such as exterior walls and roofing systems, made of “common” materials, such as wood.
While classification by type of building can be useful for understanding the ultimate objective of a project, other classification systems provide more information on legal requirements and construction risks. That said, there are still important details about the type of construction, such as whether the project is being financed with public or private funding. With real implications regarding safety, structural integrity, and fire resistance, understanding the five types of building construction is an essential part of a contractor's job. Contractors, especially those engaged in fire restoration, know better than anyone that the types of building construction are important.
Type 4 heavy wood buildings are usually old structures that use large wood as structural elements, internally and externally. However, regardless of the type of building you are building, it is essential to know the type of owner of the project, whether it is a private, state or federal project. With this type of construction, walls, partitions, columns, floors and ceilings are the least combustible when it comes to fire resistance ratings. Regardless of the project you're working on, it's imperative to understand and recognize the five types of building construction when you encounter them.
Determining which of the five types of construction your project belongs to is a key decision as part of the analysis process with the construction manager and the building designer. The construction materials and practices used in Type I construction provide the highest level of fire protection. Here, we'll review the main types of construction and the implications that each of these types has in their approach to construction and restoration. The floors and ceilings of these buildings are also not combustible, since the floors are usually covered with lightweight concrete and the roofs are insulated with foam with a metal construction.
You'll generally see type 2 fireproof construction in newer buildings or in commercial structures that have been remodeled. The construction is similar to that of type 1 buildings, but the fire resistance requirements are slightly lower. .
