However, BIM is, again, usually used to describe software with collaboration capabilities, but not necessarily a single data repository. It suffers from the same terminological creep that BIM has undergone, but fundamentally has no firm basis to start with.
The idea, however, is similar to BIM — VDC is a process of workflows that involves the management of multidisciplinary specialisms in an integrated manner, generally using technology. It is covered with multiple levels of standardisation in the French BIM standardisation roadmap. Like with the UK regulations on BIM, the terms are used to cover a number of different levels of collaboration capabilities. The processes and software of BIM produce a lot of deliverables, new ways of looking at information and new types of information — along with formal standards and common regulations.
To engage and update your processes, you need to learn the new terminology.https://volunteerparks.org/wp-content/cofametil/2306.php
Computer integrated construction: an approach to requirements engineering | Emerald Insight
We are all familiar with 2D and 3D aspects of physical space. A 4D BIM will contain schedule information about the construction sequence. When it comes to 5D and 6D, industry standard definitions vary slightly, but they most commonly reference cost and lifecycle information.
A 5D BIM will deliver information on an object or structural level about the cost of the project. These are both effectively sub-divisions of what a BIM should include, but are sometimes referenced separately. An Asset Information Model is the name sometimes given to a BIM following construction and pertains to the information included in the schematic aimed to help with the maintenance and operation of a location.
This is a group of legal guidelines set out by the Construction Industry Council in to enable a collaborative work environment while still retaining the intellectual property rights of the different liable parties. It was designed to be easily integrated into professional service agreements on a project by project basis. This person is also often responsible for other duties, likely design lead or project lead.

The PAS documents are a set of guidance and standards for BIM Level 2 that pertain to the level of model detail, model information and information exchange capabilities that must be included. There are a large number of subsets and provisions included in this set of requirements. The PAS themselves are specific to the UK and have been foundational to the development of the world standard ISO launched in which should aid the adoption of standardised collaborative ways of working in construction and reduce the dilution of terminology and processes understood worldwide under the BIM term.
It could be used in reference to the single-source-of-truth database delivered by true BIM, but is actually a redundant term for teams operating in a truly BIM-enabled environment. This term is used to reference a BIM schematic built from the combinations of several different models by importing one model into another. This might be the result of a BIM Level 2 project in which all teams work separately on graphics-first designs, or could be used to create a BIM Level 3 starting point for an existing structure.
This is an object format that enables the exchange of information across different pieces of software. These are both common construction and survey terms that reference the type of information and how detailed that information must be to meet project specifications. This is a total environmental impact assessment for a building and all of its assets. This is a term referencing a number of attempts to create open standards for BIM, enabling even greater collaboration.
In Uniclass, objects are grouped into numerical headers to enable the grouping according to type and class of the object.
A requirements engineering environment within a tightly integrated SDE
BIM is much more than software, it is a process. But, it is a process enabled by technology, and software solutions sit at the heart of that technological change. As detailed, what exactly BIM is depends on the definitions used. It could simply be the use of object-oriented CADs, the deployment of shared data environments or the creation of single-source-of-truth central data repositories and database-first design. In all cases, software gets used to access and edit different aspects of this data.
The software covered here delivers these outcomes either with universal capabilities or for very specific purposes , or provides a platform aimed to help create a shared data environment. These companies all deliver BIM software, planning tools, and collaborative aids to help deliver true BIM or BIM lite environments using any number of other design and modelling tools. It is unsurprising that AutoDesk has several 3D modelling programs built specifically for BIM processes and workflows. Bentley is another long-time architectural, engineering and construction AEC specialist, serving the market since They offer a number of reliable reality capture and 3D modelling software packages that are widely used in civil engineering and construction sectors.
Trimble is a giant in the production of both hardware and software components for reality capture and 3D modelling. They develop technology ranging from UAVs, inertial navigation system, GNSS receivers and laser rangefinders, to 3D modelling software, point cloud processing software and BIM information sharing platforms. Nemetschek is the German giant of design software, delivering CAD solutions since the s. They have a number of large subsidiaries that are all major players in the architectural, engineering and construction AEC market.
Topcon is a Japanese manufacturer of optical survey equipment and software. One of the oldest companies on this list, founded in , Topcon has been hardware focused for most of its life. However, through acquisition, they have entered the software BIM space with a globally competitive solution. BiMserver is an open source BIM software provider that is aiming to disaggregate BIM modelling and design tools from their branded silos. It is an open and stable software core that allows for the easy use of different BIM software tools.
You have already completed the first step to getting started with BIM: learning the basics of what BIM means and the possibilities it presents. The next stage is to decide what you actually want to get out of BIM. Is your interest in BIM simply to meet certain government criteria for a publicly funded construction project? Or, are you attempting to bring your processes in line with true best practices given the current state of technology? Your answers to these questions will impact how you get started with BIM and dictate the investments you need to make today. Then, build a common data environment CDE using one of a number of software platforms that can act as a data exchange.
Requirements engineering for computer integrated environments in construction
If you want to explore the true potential of BIM, you will likely need to invest in an updated set of software tools. This means looking at purpose-built and database-first software to enable seamless workflows between teams all using their own tools and diagrams while accessing the same common data system. If you go through the trouble and expense of updating your software, you need to make sure that your processes change as well. If every member of your team continues to work in isolation, very little has been gained by your investments in BIM.
More than anything, BIM is a process — it is a collaborative approach to construction that is enabled by technology, but derives its benefits from the actual outcome of specialists working together more closely. If you lose sight of that outcome, no IT investment will impact what you are able to deliver. Intellectual property IP and trade secrets are a concern for many in the construction industry.
The retention of clear categories of IP has been a more substantial stumbling block on the road to widespread adoption of fully collaborative design and information processes than many realise. The reality of BIM ownership can vary between projects.

This is something that should be set out and agreed upon at the start of a project. The problem with further levels of collaborations as expressed in BIM Level 3 is that the data does not remain separate, and the responsibility for edits of design features becomes hard to even identify. In most projects, ownership of the BIM model is retained by the building owner , meaning that teams will give up more intellectual property on a BIM project than they are used to. But, design plans are often retained in this way even using traditional techniques.
The intellectual property debate around BIM is still an evolving one. It comes down to a project by project basis to determine what is right and what actually occurs. When embarking on a BIM-enabled project, it is important to develop a clear vision for ownership and get agreement from the various contracted parties. All parties need to recognise the mutual benefit that the entire industry can gain by giving up some IP protections to create a more collaborative approach to construction and design.
To truly explore the cutting edge of BIM, you need to go beyond processes and software and look at surveys and point clouds. Point cloud technology is effectively the reverse of BIM, it starts with physical space and transforms that into a 3D model. By accessing LiDAR technology and techniques, surveyors can capture detail-rich physical environments with exacting precision, information that can be feed into BIM models for even greater quality assurance and more flexible outcomes.
Rather than just starting with a blank 3D digital space, your BIM diagram can be constructed in a digitally recreated copy of its eventual physical location. This can be a luxury, but it might also be vital to getting the design, integration with surrounding building or structural relationship to natural features correct. This ability to capture existing information is even more critical for renovation projects.
Projects can be undertaken as if the existing structure already has a BIM schematic, allowing teams to edit and manipulate structural and design details in a 3D environment that directly reflects the real location — even creating step-by-step digital plans. This same approach can be used by building and facility managers to create BIM models of their structures to provide the maintenance improvements that managers of modern structures with existing BIM schematics enjoy. This ability to match existing reality with planning can be employed throughout a construction project.
Surveys can be conducted at every stage of development to compare in unprecedented levels of detail what has actually been built to the already unprecedented level of detail maintained within the BIM model. This brings exponential improvements to quality assurance.
