(BIM-3072) The Constructible Process – Moving Beyond BIM to Build with Confidence

Author(s)/Presenter(s): Jon Fingland

Abstract:

Today’s construction stakeholders don’t care how fancy a BIM model is, they care about having buildings done on time with minimized overruns or mistakes. Traditionally, BIM has been used as a design tool to give architecture, engineering, and construction (AEC) professionals insight into the design and construction of buildings and infrastructure. But, there's more to consider beyond just BIM.  A Constructible process integrates the complete building lifecycle to manage construction activities and team collaboration and improve overall productivity. By combining design, project management and engineering models into a collaboration platform, data from different sources can be combined and used to make more informed decisions before build and beyond. This helps all stakeholders to have complete visibility with the project so that they can coordinate before they get onsite. This data-centric process also provides construction stakeholders with analytics and business intelligence that can be used to build with confidence.

This presentation will provide an overview of the constructible process along with real-world examples of how it is being used to driving greater value in the design, build and operate phases of construction.

(BIM-3073) Impact of 3D Modeling on the Estimating Process

Author(s)/Presenter(s): Steve Watt

Abstract:

With today’s advancements in construction estimating software, more contractors are taking steps to streamline and improve their cost estimating process. One approach that is gaining popularity is using 3D models during the estimating process to allow contractors to visualize the construction sequence and more accurately account for all of the building material needed. It provides a level of transparency and granularity that helps reduce potential errors and sheds light on other areas where they can save money or make recommendations about costs. The ability to highlight an item in the estimate and then have it automatically highlights all the items directly in the model, reassures that they have zeroed-in on the scope of the project.  

This presentation will explore how 3D modeling introduces more consistency into the pricing process and is giving estimators the ability to manage and integrate detailed project estimates with speed, accuracy and systemic improvement of estimating intelligence at every stage of the project.

(BIM-3080) Integrated Project Delivery Framework for Medium Size Energy Projects

Author(s)/Presenter(s): Hani S. H. Alzraiee

Abstract:

Traditional project delivery methods are inflexible for projects that require a high level of collaboration among project teams. Integrated Project Delivery (IPD) is an emerging method of delivering complex projects. This method is an efficient tool to apply when integrated collaboration, cost, and schedule are major constraints for the successful delivery of the projects. A framework for implementing IPD to a medium size energy project from the engineering phase to the commissioning phase was developed. The purpose of the framework is to capitalize on the knowledge of the all team members to increase productively which reduces project cost and duration. The framework consists of 1) project stakeholders classification; 2) disciplines identification; 3) relationships, responsibilities; and objectives matrix, and 4) monitoring, control, and feedback. The framework was implemented using Building Information Modeling (BIM) platform and project Document Management System. Synchronizing everyone's objectives in the framework and ensuring these objectives are achieved is a strategy for the success of the project delivery. The framework was implemented using actual project and was able to optimize project’s cost and schedule and substantially reduce rework.

(BIM-3097) Application of BIM in Earned Value Management for Large Scale Complex Construction Projects

Author(s)/Presenter(s): Xuejiao Liu; Chunfu Xu; Dandan Li

Abstract:

Large scale construction projects have large investment and long construction cycle. It is critical for cost control of these projects to use earned value management. Large and complex construction projects are often designed and constructed at the same time. BIM can reflect the design information of the engineering entity before the drawings.In this paper, concrete volume, room area, pipe length and other engineering data in BIM are applied to the budget value curve of the project to ensure the accuracy, and the earned value is compared with the actual value reflected by the BIM in real time, and the follow-up cost trends and the EAC can be predicted accurately, which embodies the value of BIM.

(BIM-3135) New Approaches and Strategies for a Better BIM

Author(s)/Presenter(s): Ruth Kim

Abstract:

Although BIM has been around for the last 20 years, many subcontractors, contractors and owners still struggle to see how it can impact their project teams on the job site. Like any innovation, it can be either a powerful new tool or a confusing burden depending on how it is used. Thanks to new innovations, BIM data is becoming more accessible and valuable at every stage of construction and operations, allowing construction stakeholders to access all the rich properties of a structure from anywhere. Learn about how you can advance your technology roadmap with BIM, and how to get the most out of your BIM data, whether it’s in a 3D model in design, access in the field or in an organization’s database for facilities management.

(BIM-3142) Building Information Modeling as Collaborative Working Mechanism on Construction Projects

Author(s)/Presenter(s): Charles U. Ufua

Abstract:

Collaborative working practices between disciplines in the United Kingdom Construction Industry (UKCI), still revolves around the traditional exchange of 2D drawings and associated documentation. Despite the advancements made in the use of fully collaborative 3D models and applications for design development, visualization, simulations and analysis of an asset’s buildablility and sustainablility, however, collaborative practices have largely remained 2D-based.

To this end, it would appear that the construction industry’s ability to adapt and apply new innovations in the field of information and communication technology (ICT) is limited. It is this limitation that Building Information Modelling (BIM) is expected to play a significant role in enhancing the construction industry’s ability to positively and copiously innovate and adapt more quickly to advances made in the field of ICT.

The aims of this technical paper are (a) to evaluate the concept of collaborative working in the construction industry and examine the main problems existing in contemporary collaborative frameworks; and (b) to explore to what extent, BIM as a collaborative mechanism can address these problems by focusing on the definitive benefits of BIM through it’s dimensions. This paper will encourage the adoption of BIM as part of a wider strategy to enhance productivity and efficiency on construction projects.

(BIM-3270) Comparing Efficiencies of BIM Coordination Modes in Design Phase

Author(s)/Presenter(s): Vishwambhara Kumbharathi, CEP; Dr. Pei Tang

Abstract:

Deeply involving different teams (owner, designer, fabrication, builder, operator, etc.) at design phase is important to ensure that the end design meets owner’s goals and can actually be built and operated. Connecting integrated information with the design team requires a high level of cooperation and information integration. BIM with its powerful visualization and simulation capability is an essential tool to assist the team really talk to each. A lot of research has been done on the advancements and introduction of new technologies to BIM, but the basic BIM planning, scoping and interpretation are still without specific set of guidelines, leaving the definition vulnerable to interpret in different ways. During the investigation of completed projects, it is discovered that the outcomes vary dependent on the strategies implemented in BIM scoping, interpretation, and coordination mode. This paper shared experiences and explored the guidelines for efficient and correct interpretation of BIM scoping and planning. It also compared the efficiencies of three different BIM coordination mode in design phase.
