Types of Construction

Pre-Engineered Steel

In structural engineering, a pre-engineered metal building (PEMB) is designed by a PEMB manufacturer, to be fabricated using best suited inventory of raw materials available from all sources and manufacturing methods that can efficiently satisfy a wide range of structural and aesthetic design requirements. In order to accurately design a pre-engineered building, engineers consider the clear span between bearing points, bay spacing, roof slope, live loads, dead loads, collateral loads, wind uplift, deflection criteria, internal crane system and maximum practical size and weight of fabricated members.

While pre-engineered buildings can be adapted to suit a wide variety of structural applications, the greatest economy will be realized when utilizing standard details. An efficiently designed pre-engineered building can be lighter than the conventional steel buildings by up to 30%. Lighter weight equates to less steel and a potential price savings in structural framework.

Conventional Steel Framing

In conventional steel buildings mill-produced hot rolled sections (beams and columns) are used. The size of each member is selected on the basis of the maximum internal stress in the members. Each conventional structure is designed from scratch by a structural engineer and fabricated mostly on site.

Cold Formed Metal Framing

Steel Framing, also, known as Cold Formed Steel Framing (CFS) is sheet steel that is roll formed into framing products such as C shapes & U shapes.Roll Forming is the automated process of shaping. Steel Framing is an engineered product that is offered in a large variety of sizes and gauges. It is an excellent alternative building product to wood, masonry and hot rolled steel construction.

Some of the main properties of cold formed steel are as follows:

  • Lightness in weight
  • High strength and stiffness
  • Ease of prefabrication and mass production
  • Fast and easy erection and installation
  • Substantial elimination of delays due to weather
  • More accurate detailing
  • Non shrinking and non creeping at ambient temperatures
  • Termite-proof and rot proof
  • Uniform quality
  • Economy in transportation and handling
  • Non combustibility
  • Recyclable material
  • Panels and decks can provide enclosed cells for conduits.
Wood Frame

Wood frame construction is the predominant method of building homes and apartments in the United States. Increasingly, wood framing is also being used in commercial and industrial buildings. Wood frame buildings are economical to build, heat and cool, and provide maximum comfort to occupants. Wood construction is readily adaptable to traditional, contemporary and the most futuristic building styles.

Masonry

Brick and block are two building materials that have been used for many years in masonry construction.  Modern masonry construction has an outer layer of brick; an inner layer of block and the cavity in between is filled with insulation. The build rests upon a concrete foundation. Some variations to this type of construction are to use cut stone or metal cladding rather than bricks for the outer walls. 

Tilt-Up Concrete

Tilt-Up construction, a method in which concrete wall panels are cast on-site and tilted into place. Tilt-Up construction is one of the fastest growing industries in the United States, combining the advantages of reasonable cost with low maintenance, durability, speed of construction. Tilt-Up concrete construction is not new; it has been in use for well over a century. Since the mid-1940's it has developed into the preferred method of construction for many types of buildings and structures. Nationwide, over 15% of all industrial buildings are Tilt-Up, ranging in size from 5,000 to over 1.5 million square feet.
