THE SIGNIFICANCE AND IMPACT OF BUILDING INFORMATION MODELING (BIM) IN PROJECT MANAGEMENT

ABSTRACT

T

his article focuses on the significant impact of Building Information Modeling embodied in Project Management. It brought revolutionary development to AEC industry. BIM

software such as Autodesk Revit, Nemetschek Vectorworks, Bentley Microstation, Graphisoft ArchiCAD and others. BIM provides insight to stakeholders on visualize a building under to be built in a stimulated environment. In other perspective, BIM is project stimulation in 3ds models of the project components with links to all required information connected with the planning, design, construction, and operation of the facility.

To put it into a nutshell, the objective is to ensure that precise information is allocated in the right format in given time. Therefore, the party involve can make better decision throughout the design, construction and building operation. In other word, a better administration environment is provided through these applications. Besides, it also provide Common Data Environment (CDE), a process approach allows information to be shared between all members of the project team; it is also a single source of information for the project, used to collect, manage and disseminate documentation, the graphical model and non-graphical data for the project team. It helps to facilitates collaboration between each members and avoid duplication and mistakes.

1.0 Introduction

P

roject managers in the construction industry have started to rely significantly on online collaboration and project management technology and computer aided collaborative

construction (Becerik & Pollalis, 2006).

BIM Function

Integrated IPD

Improve communication

Cost Estimation

It adapts modern administration method to avoid traditional and laborintensive communication method that cost more and inefficient in this Internet universal generation. The foundations of BIM are set on two fundamental objective, communication and collaboration; which are important for project management. Early involvement of all developers is the key of how successful implementation of BIM. Basically, the traditional project delivery systems have insufficient part in BIM based projects. Another feature of BIM is it supports Integrated Project delivery (IPD), which is a project delivery approach to integrate people, systems, business structures and practices into a collaborative process to reduce waste and optimize efficiency through all phases of the project life cycle (Glick and Guggemos, 2009). It brings all parties in AEC to produce a design that is optimized for constructability, aesthetic, quality, affordability, timeliness and seamless flow into lifecycle management.

2.0 BIM Benefits Case Studies

T

o demonstrate the significant impact of BIM in AEC construction industry in reality, a total of 2 case studies are clear to show the solution on solving the issues encounter during the design, cost management and construction phase. These case studies involve practices of 4D and 5D in their application. They are Scheduling and Estimating, which is the core function of BIM to allow adjustment during design phase, different option of design are subjected to analysis to prevent costly and time-consuming redesign at later stages in the project life cycle that is 6D and also facility management application.

2.1 Balfour Beatty Complete Luxury Hotel two-month ahead schedules Project Summary To describe in brief, Balfour Beatty has a construction project to build a luxury hotel for The City of Dallas, Texas, for its convention center.

Concerned about the economic benefits, the city decided to build a 23-story, 1,001 rooms Omni Dallas Hotel. The city wanted the facility to be constructed and operate hastily and cost-effectively as possible.

Hence, the company refers to Autodesk Building Information Modeling (BIM) solutions to keep the project under budget and on track. “BIM allowed us to explore multiple options as design decisions were being made,” says Steven Belaire, a senior project engineer for Balfour Beatty Construction. “It made it easier for us to coordinate the project, help the client make more informed decisions, and stick to the tight schedule. Having used BIM before on similar projects, we knew the time investment would be well worth it. BIM delivers benefits to virtually every aspect of a project, but it’s worth it even if you only use BIM for clash detection. Thanks in part to the efficiencies of the BIM process, we didn’t just stay on schedule—we finished two months early.”

THE SIGNIFICANCE AND IMPACT OF BUILDING INFORMATION MODELING (BIM) IN PROJECT MANAGEMENT

The Solution It began by constructing intelligent 3D models of the building and site using Autodesk® Revit® Architecture and Autodesk® Revit® Structure software. The project team began by building a basic model of the building, and then focused on the details for more delicate detail of the design, such as the structural systems and ceilings. The team constantly receives design from architects and engineers. They use DWG to compare features within AutoCAD software to pinpoint alteration, and then revised them in the model.

The team found that the ceiling clearance would be an issue in several areas during the early stage. After some refine and tally the placement of duct and electrical elements in the model. The team is able to show the issues to the client more clearly. A senior project engineer of the company mentioned that, BIM enable them to avoid potentially time consuming back and forth discussions, and found the best solution. For instance, they lowered the ceiling just 9 inches. The client still manages to get high ceiling, and the team got the space required- but with no more room than was necessary to get the job done.

Better Coordination Leads to fewer RFIs After the involvement of subcontractor, in their particular portion using their own software application. With the helps of BIM, the team was able to aggregate the information into a single source. This feature allow the team to reviews clashes with one subcontractor and able to address the issues while focus on another section of the buildings. At the end of the meeting, they aggregated the modifications into the model as real-time way of resolving issues.

The effort paid off when it came to building the project. According to another senior engineer names Karazsia, they had eliminated hundreds of clashes per floor before getting into the field. It has lower RFIs to 50% than would be typical on a project of this size. The reductions are attributed to the BIM effort. Every RFI that doesn’t happen represents real savings in time and cost.

This implementation of BIM allows the company stay ahead of the project’s original timeline. Scheduled to open in early 2013, the Omni Dallas Hotel began welcoming guest two months early. The senior project manager Jerret Click noted that the client have sufficient time to hire staff and actually open early. There’s no doubt the BIM is a solution to avoid delays and gain time throughout the project.

2.2 Aquarium Hilton Garden Inn, Atlanta, Georgia Project Summary The Aquarium Hilton Garden Inn project comprised a mixed-use hotel, retail shops, and a parking deck. Brief project details are as follows: Project scope

46million dollar, 484,000-square-foot hotel and parking structure

Delivery method

Construction manager at risk (CM at risk)

Contract type

Guaranteed maximum price

BIM scope

Design coordination, clash detection, and work sequencing

BIM cost

90,000 dollar, or 0.2% of the project budget (40,000 dollar paid by owner)

Cost benefit

Over 200,000 dollar attributed to elimination of clashes

Schedule benefit

1,143 hours saved

Although the project wasn’t start by using BIM technology to design in the early stage, the GC led the project team to develop architectural; structural; and mechanical, electrical, and plumbing models of the proposed facility, as show in figure 2.2.1. These models were created by detail-level information from subcontractors based on drawing from the designers.

The GC has begun to implement the uses of clash detection analysis on these models after review. BIM application allows the GC to pinpoint potential overlap between various structural and mechanical systems. During the design development phases, 55 clashes were found, which avoid of unnecessary expenses of 124,500 dollar. In this transition, a net saving of 34,500 dollars based on the original BIM development cost of 90,000 dollars.

At the construction phase, the clashes were detected and resolved later to be update in the model. These clashes were shared among the design team via CDE and a numbered collision log with a record of individual figure of each collision. The collision cost savings values were based on estimates for making design changes. A total of 590 clashes detected in the model enable the project save up estimated at 801,565 dollars, as show in the figure 2.2.2.

In essence, the Aquarium Hilton Garden Inn project realized the benefit BIM technology could offer and certainly the outcome has exceeded the expectations of the owner and other project team members. The cost benefits to the owner were significant, and the unknown cost were avoided through collaboration, visualization and understanding, and identification of conflicts in early stage were in addition to the reported savings; figure below shown the application of the BIM sequences.

At the end of the project, the architect and GC began to use BIM technology on all major projects, and the owner used the developed building information model for sales and marketing presentation (Azhar and Richter 2009).

3.0 The Significance And Impact Of Building Information Modeling quality benefits that BIM provides are most valuable for project The managers concerning keeping control of a project; according to Haughey (2011b), the project manager is responsible for keeping control of a project from project initiation to closure. When a building information model is utilized in the design phase, project progression can be limpidly visually perceived when the disciplines’ models are uploaded.

3.1 BIM Avail on Workflow Improve Time and Cost Management This sanctions the project manager to estimate project schedule and budget more accurately in comparison with traditional projects, where the disciplines often want to preserve their drawings as long as possible until culminated. The results showed that many of the interviewed project managers visually perceived astronomically immense potential ameliorations from linking the building information model to time. This would provide the project manager with better control emanating from more precise time estimates and better orchestrating of the construction phase. The ability to orchestrate the execution of the construction phase would be a consequential benefit for the contractor, and would lead to ameliorate performance in the project holistically. The BIM Project Execution Orchestrating Guide (2009) states that time estimation provide better understanding of construction plans. Cost estimation can provide better control of the economical aspects of a project, and optimize the value a client can obtain from investments. According to the BIM Project Execution Orchestrating Guide (2009), cost estimation can be applied to evade cost overruns as well as to explore different design options within the client’s budget. According to the interviewed project managers, the most astronomically immense gains of cost estimation would be for the contractor, reducing costs in the construction phase. When stakeholders perform better in their individual tasks, this will indirectly affect the project manager positively. It is more likely that the project will be prosperous and there will be better profit margins for all stakeholders, including the project manager. Jongeling claims that there are substantial cost savings in BIM projects, in comparison to projects where 2D-CAD is utilized; a lower end estimation of the savings are 4 percent of the building costs, the net cost savings (CHALMERS, Civil and

Environmental Engineering, Master’s Thesis 2011:104 27) for the architect and technical consultants is between 0 and 20 percent, and for the contractor 4 percent.

3.2 BIM Assist Client Decision Making Through Visualize

Alluding to the past passage, BIM has unmistakably demonstrates that it gives a superior portrayal of genuineness. This makes it a great deal simpler to comprehend and outwardly see the outcomes of choices that are made. For example, the visual impacts of distinctive exterior materials as block and compo can be optically observed. The outcome is that a superior substratum for choices is offered through BIM in examination with conventional activities. A principle reason that higher quality can be accomplished when BIM is used is that data just should be entered once in BIM ventures in correlation with customary activities. Also, less the reality of the situation will become obvious eventually squandered on never-ending work. Case in point, when alteration and supplementary work (ÄTA) is performed, it is just obligatory to actualize changes one time, and all drawings connected to the model will be redesigned, in lieu of physically overhauling an arrangement of isolated drawings. Another advantage is the capacity to perform conflicts controls in the outline stage.

Here the models of distinctive orders are converged into a solitary model and focuses where the structures conflicts, are recognized. These focuses can then be corrected, keeping in mind the end goal to shun issues that would some way or another happen in the development stage. The meetings

 asserted that more or less proximately all conflicts that they would unremarkably get would be shunned by performing conflict controls. At the point when using BIM, it encourages for the venture director to control a task so it takes after the time arrangement amid the outline stage. Amid coordinating gatherings, partners, for example, the modeler and electrical designer report to the venture chief what they have achieved in their workassignments. In BIM ventures, the undertaking director will ken accurately what every partner has fulfilled until every meeting, as they will transfer the most recent rendition of their models where everything can be pellucid optically observed. In conventional activities, there is more space for skeptically with respect to what have really been expert, as partners slope to preserve their drawings to the extent that this would be possible, throughout the process.

With BIM, there is a 3D model accessible which expands the entrance to various types of dissects of for occasion vitality, light and acoustics. In correlation, just the information mandatory to run an investigation must be incorporated to the building data model in BIM ventures, for occurrence the confining capacity of diverse materials with a specific end goal to perform a vitality examination. Consequently, the time and expense to perform breaks down is significantly less, and subsequently more investigates are frequently performed which builds the quality. A significant number of the interviewees longed for more execution of connecting the building data model to time and trusted that this would authorize for more viable arranging of the development stage. The time linkage can be habituated to outwardly reenact diverse situations and in which arrange distinctive parts of the development could be fabricated. The points of interest and drawbacks of the diverse options of directing the development can be weighed against one another to concoct an ideal arrangement. This empowers early recognition of arranging blunders, in lieu of understanding the coordinating missteps later on when development is in progress, which can be exorbitant. At the point when certain materials ought to arrive and where the best areas are to place cranes on the development site, the logistics could be arranged more effectively. The time linkage to a 3Dmodel could moreover be used by the site supervisor to optically perceive how the time arrangement is taken after, and in addition to convey building arrangements for the development to subordinates, for occasion by what purpose of time a sure divider ought to be raised. (CHALMERS, Civil and Environmental Engineering, Master's Thesis 2011:104 23). The building data model can withal be joined with costing records for the distinctive materials that are used. This empowers cost estimation where materials and development arrangements can be assessed from a conservative point of view. Taken a toll estimation can be backup when talking about distinctive choices with the customer from a prudent perspective; it can for instance be undaunted what the customer can acquire from a sure measure of contributed fortune.

THE SIGNIFICANCE AND IMPACT OF BUILDING INFORMATION MODELING (BIM) IN PROJECT MANAGEMENT

CONCLUSION Through the previous hundreds of years an important increment in programming arrangements has been displayed in the AEC business. Both 2D-and 3D-product have superseded the more customary handcrafted outlines in the configuration and development stages. Plan and building orders have slowly habituated to the use of 3D configuration arrangements. Today, the actualized models are used for development and practical examination and additionally for illustrative purposes. BIM is a procedure which characterizes how to use 3D-articles for advanced data trade between proprietors, planners, engineers, foremen, suppliers, and so on. The BIM philosophy opens for geometry and data to be reused for more than one indicate, making the outline and development a more productive procedure. Building data is used by various orders in an amalgamated cooperation, which obliges that jobs inside of configuration and development comprehend the desiderata of one another.

AEC industry should fully implement the use of BIM into their system especially in Malaysia. BIM shows a promising growth in working culture and office workflow. Moreover, BIM allows the industry in Malaysia keep up with the competition in this globalization era. Research shows that the feedbacks of implementation of BIM are positive, this hinders the future of AEC industry dependency on technology application.
