Cloudalize’s BIM Phrase Book

Build the Future

Encountering Building Information Building (BIM) for the first time whether as a student or a professional can be daunting. The team here at Cloudalize was no different.  We too had to learn the BIM jargon, industry-specific phrases and acronyms.

That’s why we took the time to put together a BIM phrase book as a quick reference guide to BIM.

Cloudalize’s BIM phrase book is all you need to understand the terminology of Building Information Modelling (BIM).

Architectural Supplemental Information (ASI)

Architect’s Supplemental Instructions (ASI) are formal directions from an architect to resolve minor issues which may arise during a construction project. ASI advise how work should advance to resolve the issues concerned outside the contract signed between the contractor and the client. the ASI are included in any handover document prepared.

Bill-of-Materials

A Bill-of-Materials (BoM) is a list of raw materials, components and parts needed for the manufacture of an end product or construction of a building. BoM helps the project stakeholders to plan raw material purchases and requirements. It provides foresight in estimating the cost of materials and, ultimately, reducing cost.

BIM Maturity Levels

The BIM Maturity Levels explain to which a company’s supply chain can operate and exchange information of the project with other stakeholders in the project life cycle. It started with Level 0 during the 1990s.

BIM-to-Field

BIM-to-Field is harnessing the accurate digital data contained within the 3D model and using it on-site for accurate and efficient operations, construction and maintenance.

Design-Bid-Build

Design-Bid-Build (DBB) is the traditional method of delivering a construction project from beginning to end. It remains the most widely used method and consists of three elements: 

  • The design phase; 
  • The tendering phase and; 
  • The construction phase. 

It is still the preferred method because the project stakeholders will never have design surprises and it limits delays and changes and therefore the cost and schedule can be accurately predicted.

Digital Elevation Model (DEM)/Digital Terrain Model (DTM)

A Digital Elevation Model (DEM)/Digital Terrain Model (DTM)  is a mathematical representation of the surface of the Earth in 3D. All buildings, vegetation and public services are removed from it to visualise just the terrain. DTM/DEM are obtained by surveying the area by a surveying drone and are used by civil engineers and geodetic engineers and are used in new modern constructions.

EU Directive 2014/24/EU

The European Union (EU) Directive 2014/24/EU on public procurement establishes the need for the use of data and digital tools (BIM) in the procurement process of construction work, services and supplies from September 2018. Directive 2014/24/EU is binding and must be implemented by EU member states. 

Geographical Information Systems (GIS)

Geographical Information Systems (GIS) is software which manipulates, analyses and visualises geospatial information. GIS is a straightforward mapping tool however, the data can come from many sources and therefore is multilayered. 

Geospatial

Geospatial is the collective name for a range of modern tools which help analyse location-based data and information. Accurate and reliable geospatial data is obtained from Global Satellite Navigations Systems (GNSS) equipment which track GNSS constellations such as GPS, QZSS, BeiBou, GALILEO and GLONASS. It is commonly used by surveying engineers when plotting the points of construction site.

Isometric Drawing

Isometric Drawing or projection is a type of 3D drawing when the x, y and z axis are all at 120°. The advantage of isometric drawings is that the object can be freely oriented without redrawing it so the project stakeholders can visualise the entire building or object under construction. 

Levels of Development (LOD)

Levels of Development (LOD) allows BIM project stakeholders to stay up-to-date with progress. It defines the information, data and linked documentation at different milestones of the project. Ultimately, it facilitates the BIM projects reliability. 

Public-Private Partnerships (PPP)

Public-private partnerships (PPP) are when private-enterprise and the civil administration – i.e. government – work together to complete a project to provide public services. PPPs have been used to fund and construct infrastructure projects around the world including dykes, hospitals, public transport systems and bridges. 

Request-For-Information (RFI)

Request-for-Information (RfI) is a document used to obtain information about a product, service and suppliers of a construction or manufacturing form. RfI are formal and are a preliminary document sent early in the process about a firm’s ability to meet specific needs and to solve unique issues that it has for its end product or building. 

Request-For-Proposal (RFP)

A Request-for-Proposal (RfP) comes after a RfI. It is a formal document which details information from an external party to solicit bids to complete a project or a particular objective of the project. The RfP outlines the tendering process, contract terms and terms of reference. When a RfP is sent, it can be safely assumed that there are multiple parties to the tendering process.

Statement-of-Work (SoW)

A Statement-of-Work (SoW) is used on-site of the project to detail the BIM project’s work requirements. It can outline the deliverables of the project, the scope of the project, the Key Performance Indicators (KPIs) as well. It is useful for project and contract management as it outlines the liabilities, agreements and division of responsibilities between the client and the contractors. 

Smart City

A smart city is an urban area where Internet-of-Things (IoT) is deployed to gain insights for the benefits of the whole community. A smart city relies on modern and digital solutions to improve life for goals and optimise services for the commercial sector. The end goal is efficient delivery of public services, responsive municipal authorities, safer streets and meeting the needs of the population into the future.
