Rebar, known when massed as reinforcing steel or reinforcement steel, is a steel bar used as a tension device in reinforced concrete and reinforced masonry structures to strengthen and aid the concrete under tension. Concrete is strong under compression, but has low tensile strength. Rebar significantly increases the tensile strength of the structure. Rebar's surface features a continuous series of ribs, lugs or indentations to promote a better bond with the concrete and reduce the risk of slippage.

The Construction Specifications Institute (CSI) is a United States national association of more than 8,000 construction industry professionals who are experts in building construction and the materials used therein. The institute is dedicated to improving the communication of construction information through a diversified membership base of allied professionals involved in the creation and management of the built environment, continuous development and transformation of standards and formats, education and certification of professionals to improve project delivery processes, and creation of practice tools to assist users throughout the facility life-cycle. The work of CSI is currently focused in three areas being standards and publications, construction industry professional certifications, and continuing education for construction professionals.
The J. Edgar Hoover Building is a low-rise office building located at 935 Pennsylvania Avenue NW in Washington, D.C., in the United States. It is the headquarters of the Federal Bureau of Investigation (FBI).
Waterproofing is the process of making an object or structure waterproof or water-resistant so that it remains relatively unaffected by water or resisting the ingress of water under specified conditions. Such items may be used in wet environments or underwater to specified depths.
Dimension stone is natural stone or rock that has been selected and finished to specific sizes or shapes. Color, texture and pattern, and surface finish of the stone are also normal requirements. Another important selection criterion is durability: the time measure of the ability of dimension stone to endure and to maintain its essential and distinctive characteristics of strength, resistance to decay, and appearance.
MasterFormat is a standard for organizing specifications and other written information for commercial and institutional building projects in the U.S. and Canada. Sometimes referred to as the "Dewey Decimal System" of building construction, MasterFormat is a product of the Construction Specifications Institute (CSI) and Construction Specifications Canada (CSC). It provides a master list of Divisions, and Section numbers with associated titles within each Division, to organize information about a facility’s construction requirements and associated activities.
A raised floor provides an elevated structural floor above a solid substrate to create a hidden void for the passage of mechanical and electrical services. Raised floors are widely used in modern office buildings, and in specialized areas such as command centers, Information technology data centers and computer rooms, where there is a requirement to route mechanical services and cables, wiring, and electrical supply. Such flooring can be installed at varying heights from 2 inches (51 mm) to heights above 4 feet (1.2 m) to suit services that may be accommodated beneath. Additional structural support and lighting are often provided when a floor is raised enough for a person to crawl or even walk beneath.
Structural steel is a category of steel used for making construction materials in a variety of shapes. Many structural steel shapes take the form of an elongated beam having a profile of a specific cross section. Structural steel shapes, sizes, chemical composition, mechanical properties such as strengths, storage practices, etc., are regulated by standards in most industrialized countries.
Oxygen-free copper (OFC) or oxygen-free high thermal conductivity (OFHC) copper is a group of wrought high-conductivity copper alloys that have been electrolytically refined to reduce the level of oxygen to 0.001% or below. Oxygen-free copper is a premium grade of copper that has a high level of conductivity and is virtually free from oxygen content. The oxygen content of copper affects its electrical properties and can reduce conductivity.
The SAE steel grades system is a standard alloy numbering system for steel grades maintained by SAE International.
A cost estimate is the approximation of the cost of a program, project, or operation. The cost estimate is the product of the cost estimating process. The cost estimate has a single total value and may have identifiable component values.
Steel casing pipe, also known as encasement pipe, is most commonly used in underground construction to protect utility lines of various types from getting damaged. Such damage might occur due to the elements of nature or human activity.
A specification often refers to a set of documented requirements to be satisfied by a material, design, product, or service. A specification is often a type of technical standard.
Bituminous waterproofing systems are designed to protect residential and commercial buildings. Bitumen is a material made up of organic liquids that are highly sticky, viscous, and waterproof. Systems incorporating bituminous-based substrates are sometimes used to construct roofs, in the form of "roofing felt" or "roll roofing" products.
ASTM A325 is an ASTM International standard for heavy hex structural bolts, titled Standard Specification for Structural Bolts, Steel, Heat Treated, 120/105 ksi Minimum Tensile Strength. It defines mechanical properties for bolts that range from 1⁄2 to 1+1⁄2 inches in diameter.
The International Green Construction Code (IGCC) is a set of guidelines that aim to improve the sustainability and environmental performance of buildings during their design, construction, and operation. It was introduced by the International Code Council (ICC), a non-profit organization that provides building safety and fire prevention codes for the United States and other countries. It is a model code designed to be mandatory where it is implemented.
MasterSpec is a master guide building and construction specification system used within the United States by architects, engineers, landscape architects, and interior designers to express results expected in construction. MasterSpec content and software is exclusively developed and distributed by Deltek for the American Institute of Architects (AIA). It was developed in 1969 by the AIA to provide architects a means to create technical specifications without spending a lot of time researching products and writing up to date technical specifications from scratch. Content for MasterSpec is vetted by AIA-sponsored architectural and engineering review committees. In 2019, the company was acquired by Deltek, Inc.
Micronized rubber powder (MRP) is classified as fine, dry, powdered elastomeric crumb rubber in which a significant proportion of particles are less than 100 µm and free of foreign particulates. MRP particle size distributions typically range from 180 µm to 10 µm. Narrower distributions can be achieved depending on the classification technology.
A cost database is a computerized database of cost estimating information, which is normally used with construction estimating software to support the formation of cost estimates. A cost database may also simply be an electronic reference of cost data.
