Abstract: With great tools on the market to perform 4D scheduling for the heavy civil construction industry, a major Canadian utility company recently enhanced its virtual construction 4D scheduling practice on two new facilities. The latest simulations included equipment, just-in-time handling, equipment storage and displacement, space identification and reservation, distinct trade and contract identification in addition to traditional time sequencing. This development included multiple types of contracts: mechanical, electrical, architecture and turbine-generating equipments in addition to excavations, concrete and superstructure. This has been done using both owner and contractors schedules (baselines and updates) and 3D mock-ups for hydroelectrical powerhouse projects. Simulations were performed both at the master schedule level and for specific contracts with consideration of the different but appropriate levels of details. The 4D process has so far been internal to the owner's organisation for project information validation only. 3D ViaTM Composer Player Pro was used to generate light program files that are easily interoperable by the project control staff. The system helps office personnel with strategic decisions and field personnel with operational considerations.
(BIM-2558) Building Information Modeling For Infrastructure Projects – Emphasis on 4D, 5D and 6D

Abstract: Building Information Modeling has been widely used in the building construction industry for nearly a decade now, but in the civil infrastructure industry it is not that widespread due to many reasons like massive scale, differences in geometry involved and the types of software available currently. This paper will discuss how the BIM technology is being used in civil infrastructure sector specifically taking a detailed look at the 4D Scheduling/Sequencing, 5D Cost Estimating and 6D Visualization. Introduction to different types of software available in market, the process to perform these functions, benefits of using BIM and limitations, difficulties and lessons learned. It is absolutely certain that the currently underused BIM techniques for civil infrastructure will develop and overcome all the limitation. All the stake holders of the infrastructure projects will have to realize that BIM adoption for their projects is more about cultural change than technological enablers to maximize profit.
(BIM-2569) Housing Price Estimation Using Statistical Methods and GIS Technology

Abstract: The current mass appraisal models have not utilized real assessment data in their formulation, and the price variations have not been plotted on GIS maps. This paper presents a statistical appraisal model for housing, and maps the results to illustrate variations in home prices based on neighborhoods. It was previously reported that six variables had the greatest effect on the price of a home: frontage width, parcel depth, age, living area, architectural style, and neighborhood. The model used 2009 housing assessment data of 33,342 homes of a town in Western New York. The model had high accuracy with a R2 value of 0.9046, and tested well on validation. The analysis revealed that neighborhood exerts the maximum influence on housing price. This model can be used for mass appraisal of housing in towns with similar characteristics. The visualization provided by the GIS maps can help municipalities resolve inequities within and between neighborhoods.
(BIM-2632) Infrastructure: Visualizing Project Success
Author(s): Connor Christian; Andy Kayhanfar
Tuesday, June 13 10:45-11:45/Celebration 4
Abstract: An inside look at how building information modeling (BIM) technology can help visualize project success on the world’s largest projects. Through revolutionary technology, owners and contractors can envision project success from design to construction, while project managers can aggregate model data and quickly react to changes in real time. As an exploration of the benefits of BIM technology, this paper dives into maximized project performance through alleviating impacts caused by sudden schedule and design changes. It also looks at better-tracked progress and managed assets through linking project data to BIM. Lastly, all of this is tied together through a single visual model where any project dimension can be accessed. Large capital project requirements are changing — leverage BIM to stay ahead of the curve.
(BIM-2697) Integrating Building Information Modeling with Project Schedule

Abstract: Design-Build programs in the past have encountered many challenges. Creating one vision where all stakeholders viz. owners, architects, engineers, and contractors can be in one forum to create a common goal is always a desire for a design-build delivery model. 4D BIM can create this forum where the virtual model can be used to exchange information between the stake holders and this new wave of 3D technology can transform to provide simulation of virtual construction. A 4D model is accessible to all the stake holders and foster exchange of ideas in variety of ways. It helps mitigate risk, constructability review, analyze scope changes and delay analysis through visual representation and also helps in resource utilization.
This paper addresses the methods involved in implementation of a 4D BIM technology for a design-build capital program for a major airport. The author will elaborate his experience in working with a diverse team and implementing 4D BIM for building a brand new concourse in an existing airport. The author will also highlight the challenges encountered along with the benefits reaped.
(BIM-2713) (Workshop) Moving Beyond Yesterday to Advance Tomorrow (with Legos)
Author(s): Dr. Ralph Kreider
Monday, June 12 10:00-12:15/Celebration 4
Abstract: Imagine for a minute that the world of construction is only beginning to formalize its processes. How would it look different from what we are accustomed to today? Over the past decade, technology has advanced at an exponential rate, yet in reality, we have only seen a fraction of what's been predicted. Despite the advances, we are still building facilities using antiquated practices. Join Ralph Kreider, director of digital facilities for MBP to answer the following questions... Why are we slow to see technological advances in the construction industry? While other industries are getting more productive and seeing a decline in product costs, construction productivity continues to decline and costs continue to soar. What is holding us back? How can we progress in seeing the efficiencies promised by new technologies? Each of us can make a difference, not by doing more, but by doing it differently. Change may be uncomfortable. What discomfort are we willing to bear today, so that we can advance tomorrow? They will experience how to think different through a hands-on Lego Experience. Are you ready to be a kid again? After this session, participants will have some of the tools necessary to demand improved processes on their projects.
