Modeling project documents

Giovanni C. Migliaccio, Len Holm
From an information technology viewpoint, the widespread adoption of CAD tools made it possible to think more boldly, and it initiated a push toward the full integration of multiple computer tools for estimating, scheduling, and planning into a single family of tools that operated around a geometric model of the built environment project. This new generation of tools does not simply support existing design processes—it has radically transformed both design and construction processes through integration and virtualization. Two families of virtual design and construction (VDC) tools have been developed in support of vertical and horizontal projects, namely the building information modeling (BIM) and civil information modeling (CIM) tools that will be discussed in the rest of this chapter. Differently from CAD tools, which were intended as standalone programs, BIM/CIM tools are modular. Each major provider of BIM/CIM tools relies on its latest generation of CAD tools to serve as the core for a wider family of tools that interconnect with each other to support most design and construction processes. Whereas 2D drawings are still prevalent in contracting, this technological advance is also introducing the use of 3D models as an additional contractual document.
Virtual design and construction

The term “virtual design and construction”, or VDC, is used to emphasize the difference between design and construction using BIM on the one hand, and design and construction using traditional tools, primarily 2D drawings on the other hand. The word “virtual” distinguishes VDC from “real” construction, in the same way that virtual reality is a digital expression of reality. Where fully implemented, VDC entails: generating a digital design model using BIM tools;simulating and analysing the performance of the digital building model using software;planning the construction process using BIM tools, by rebuilding or refining the digital design model to generate a digital construction model, and by compiling an integrated digital construction plan;simulating and analysing the digital construction plan using software;building the building according to the digital model by executing the construction plan in reality, including digital monitoring and recording of the construction process;recording the “as-built” state of the building by updating the digital construction model.
Safety, quality and BIM drive lean transformation at DPR

Providing measurably more value is DPR’s guiding principle in using technology to enhance project delivery. As a long-established leader in Virtual Design and Construction (VDC) and Building Information Modelling (BIM), Andrew Fischer of DPR writes: To name just a few benefits, when VDC apps are used correctly, project teams can improve productivity, reduce field clashes, enhance building documentation, and feed into management systems, which can result in lower long-term costs.
IPD and BIM-focussed methodology in renovation of heritage buildings

Succar (2009) considers BIM as an integration of product and process modelling, and not just as a disparate set of technologies and processes. He divided the process deliverables into products and services, including drawings, documents, virtual models/components, physical components, structures, and facilities. On the other hand, the highly cited Simple Framework of Fischer et al. (2014, 2017) combines four key elements: integrated organisation, process integration, Integrated Information, and finally integrated system to create a high-performing building through virtual design and construction (VDC). The authors position the product as a starting point in their IPD framework. A high-performance building that provides measures against the four categories of criteria for the value stakeholders seek (economic, social, environmental, and user value).
Exploring the benefits of structured information with the use of virtual design and construction principles in a BIM life-cycle approach
Published in Architectural Engineering and Design Management, 2019
Mikkel Toppel Andersen, Ann-Louise Findsen
Virtual design and construction (VDC) is a new way of digitally working with projects, supported by BIM. VDC is about, how to manage information and how to organize people and their work methods so that the vision and goal for the project is reached. Everyone, who works with projects and participates within the process needs to have the ability to collect, store and distribute digital construction knowledge and information during the project life cycle. This calls for a more methodical perspective and information structure during the execution of a project compared to a more traditional approach. If the same mistakes are made in every project, it is important to have some transferable framework that all participants can enact and work within. One of the biggest questions to be considered when planning and working with the VDC/BIM process should be ‘What should we use the DIGITAL objects and information for?’ and ‘What do the different participants need to deliver at certain points to drive the process?’.
Design for manufacture and assembly in construction: a review
Published in Building Research & Information, 2020
Shang Gao, Ruoyu Jin, Weisheng Lu
There are two main areas of manufacturing that construction can benefit from (Kagioglou et al., 1998), namely new product development and the operational/production processes. Much has been discussed on the second area. Indeed, a number of production and operation philosophy and practices such as Just in Time (JIT), lean production and others originated in the manufacturing sector. This paper concentrates on the first, which related very closely to the design process, with a focus on design for manufacture and assembly (DfMA). This study begins with a review of DfMA in the manufacturing, and notes DfMA takes manufacturing and assembly into account during the product design, but also these considerations must occur as early as possible. The review of general principles of DfMA reveals that these principles are actually in line with the heuristic principles of Koskela’s (2000) flow concept of production. Through a literature review, this paper discovered that DfMA can be deployed in three forms: A holistic design process that encompasses how structure or object will be manufactured and assembled guided with sets of principles;An evaluation system that can work with virtual design and construction (VDC) to evaluate the efficiency of manufacturing and assembly; andA game-changing philosophy that embraces the ever-changing to prefabrication and modular construction technologies.
