Industry Foundation Classes
The Industry Foundation Classes (IFC) is a CAD data exchange data schema intended for description of architectural, building and construction industry data (ABCII). The IFC file format is based on ISO 10303-21 standard and definitions of ABCII are documented by using underlying EXPRESS (data modeling language), EXPRESS. It is a platform-neutral, open data schema specification that is not controlled by a single vendor or group of vendors. It is an object-based data schema with a data model developed by buildingSMART (formerly the International Alliance for Interoperability, IAI) to facilitate interoperability in the architecture, engineering and construction (AEC) industry, and is a commonly used collaboration format in Building information modeling (BIM) based projects. The IFC model specification is open and available. It is registered by ISO and is an official International standard, International Standard ISO 16739-1:2024. Because of its focus on interoperability the Denmark, D ...

Building Information Modeling
Building information modeling (BIM) is an approach involving the generation and management of digital representations of the physical and functional characteristics of buildings or other physical assets and facilities. BIM is supported by various tools, processes, technologies and contracts. Building information models (BIMs) are computer files (often but not always in proprietary formats and containing proprietary data) which can be extracted, exchanged or networked to support decision-making regarding a built asset. BIM software is used by individuals, businesses and government agencies who plan, Building design, design, construction, construct, operate and maintain buildings and diverse hard infrastructure, physical infrastructures, such as water, refuse, electricity, gas, communication utilities, roads, railways, bridges, ports and tunnels. The concept of BIM has been in development since the 1970s, but it only became an agreed term in the early 2000s. The development of sta ...

BIM Collaboration Format
The BIM Collaboration Format (BCF) is a structured file format suited to issue tracking with a building information model. The BCF is designed primarily for defining views of a building model and associated information on collisions and errors connected with specific objects in the view. The BCF allows users of different BIM software, and/or different disciplines to collaborate on issues with the project. The use of the BCF to coordinate changes to a BIM is an important aspect of OpenBIM. The format was developed by Tekla and Solibri and later adopted as a standard by buildingSMART. Most major BIM modelling software platforms support some integration with BCF, typically through plug-ins provided by the BCF server vendor. Although the BCF was originally conceived as a file base there are now many implementations using the cloud-based collaborative workflow described in the BCF API, including Open Source implementation as part of the Open Source BIM collective. Research work has b ...

Facility Management
Facility management or facilities management (FM) is a professional discipline focused on coordinating the use of space, infrastructure, people, and organization. Facilities management ensures that physical assets and environments are managed effectively to meet the needs of their users. By integrating maintenance, safety, efficiency, and comfort, FM supports organizational goals within the built environment. The profession operates under global standards such as ISO 41001 and is guided by organizations like the International Facility Management Association (IFMA). History The concept of facilities management originated in the 1960s, primarily in the context of IT systems management. The term was coined by IBM alumnus and Electronic Data Systems founder Ross Perot, to describe the integration of network management and support services. Over time, it expanded to include broader elements of building and operational management. Facility management as integral to the processes of str ...

National Institute Of Building Sciences
The National Institute of Building Sciences is a non-profit, non-governmental organization that identifies and resolves problems and potential issues in the built environment throughout the United States. Its creation was authorized by the U.S. Congress in the Housing and Community Development Act of 1974. Board of directors The Institute is governed by a board of directors which consists of 21 members. All members serve for terms of three years, with a third of the board up for new terms each year. The President, with the advice and consent of the Senate, appoints six members to represent the public interest. The remaining 15 members are elected from the nation's construction industry, including representatives of construction labor organizations, product manufacturers, and builders, housing management experts, and experts in building standards, codes, and fire safety, as well as public interest representatives including architects, professional engineers, officials of Federal, Sta ...

Infrastructure
Infrastructure is the set of facilities and systems that serve a country, city, or other area, and encompasses the services and facilities necessary for its economy, households and firms to function. Infrastructure is composed of public and private physical structures such as roads, railways, bridges, airports, public transit systems, tunnels, water supply, sewers, electrical grids, and telecommunications (including Internet connectivity and broadband access). In general, infrastructure has been defined as "the physical components of interrelated systems providing commodities and services essential to enable, sustain, or enhance societal living conditions" and maintain the surrounding environment. Especially in light of the massive societal transformations needed to mitigate and adapt to climate change, contemporary infrastructure conversations frequently focus on sustainable development and green infrastructure. Acknowledging this importance, the international co ...

Structural Engineering
Structural engineering is a sub-discipline of civil engineering in which structural engineers are trained to design the 'bones and joints' that create the form and shape of human-made Structure#Load-bearing, structures. Structural engineers also must understand and calculate the structural stability, stability, strength, structural rigidity, rigidity and earthquake-susceptibility of built structures for buildings and nonbuilding structures. The structural designs are integrated with those of other designers such as architects and Building services engineering, building services engineer and often supervise the construction of projects by contractors on site. They can also be involved in the design of machinery, medical equipment, and vehicles where structural integrity affects functioning and safety. See glossary of structural engineering. Structural engineering theory is based upon applied physics, physical laws and empirical knowledge of the structural performance of different ...

Procurement
Procurement is the process of locating and agreeing to terms and purchasing goods, services, or other works from an external source, often with the use of a tendering or competitive bidding process. The term may also refer to a contractual obligation to "procure", i.e. to "ensure" that something is done. When a government agency buys goods or services through this practice, it is referred to as '' government procurement'' or public procurement. Procurement as an organizational process is intended to ensure that the buyer receives goods, services, or works at the best possible price when aspects such as quality, quantity, time, and location are compared. Corporations and public bodies often define processes intended to promote fair and open competition for their business while minimizing risks such as exposure to fraud and collusion. Almost all purchasing decisions include factors such as delivery and handling, marginal benefit, and fluctuations in the prices of goods. Org ...

Project Management
Project management is the process of supervising the work of a Project team, team to achieve all project goals within the given constraints. This information is usually described in project initiation documentation, project documentation, created at the beginning of the development process. The primary constraints are Scope (project management), scope, time and budget. The secondary challenge is to operations research, optimize the Resource allocation, allocation of necessary inputs and apply them to meet predefined objectives. The objective of project management is to produce a complete project which complies with the client's objectives. In many cases, the objective of project management is also to shape or reform the client's brief to feasibly address the client's objectives. Once the client's objectives are established, they should influence all decisions made by other people involved in the project– for example, project managers, designers, contractors and subcontractors ...
