Building Information Modeling (BIM) and Interoperability Issue

AEC firms are adopting high-tech technology to augment their productivity. The construction and engineering sector extensively apply technologies like high-resolution aerial photogrammetry, oblique imagery, radar-derived digital terrain models and laser scanning to gather reality information.
Building Information Modelling (BIM) motivates various professional disciplines for creating effective communication and collaboration among themselves. As for instance, construction companies connects a BIM model to project management software facilitating 4D and 5D views of projects so that the risk associated with budget overruns may be reduced and  the scheduling of material deliveries and work crews become more apparent. 4D model integrates the dimension of time applied to visualize and control construction programmes/schedules.  5D BIM model utilizes cost data, computerizes quantity takeoffs for cost estimating, and if combined with 4D may result in cash flow study.  Additional dimensions like 6D and 7D are included in the model to provide ‘health & safety’ or ‘sustainability’.

BIM technology becomes more and more mainstream in the construction sector

With the advent of Business information modeling (BIM) technology, the construction industry becomes high-tech. All the project stakeholders utilize BIM in the construction process that range from design and construction firms to building operators. Besides architects, project managers, contractors and trades workers, engaged with a construction process, are also being benefitted.

BIM can be defined as 100 per cent a game-changer for the (construction) industry. BIM technology refers to a central technology hub that represented with numerous diverse software packages taking into consideration the complete lifestyle of a building. All concerned parties of a construction process get the ability to form, synchronize, document, control, revise, transform and analyze every single characteristic of design and construction in real time with a collective, central hub.

BIM is applied to renovate the system buildings are designed, the system they're planned and the system they're managed. BIM based technology can transfer the paradigm to get better output.

BIM is now also playing an important role for infrastructure projects. More than 27 per cent of the civil engineers are utilizing BIM for infrastructure projects.

BIM is also going to be fruitful for making the efficiencies required for advancing productivity among a construction sector labour short-age..

Trades workers working on the ground also utilize BIM knowledge to set up, to create alterations or to revise projects faster in real time. BIM surpasses it’s 3-D modeling capability to incorporate a potentially unrestricted number of dimensions -  for example cost, time and quality.

BIM consist of all components of a project during construction process that may range from services or the structure itself.

By applying BIM, the structural engineers can easily find out any potential clashes at the beginning stage along the way as changes are unavoidably occurred. Any costly overruns can be easily detected before the actual structure is presented in the field saving  millions of dollars.

Building Information Modeling & Risk Management

BIM has been widely implemented in architectural-engineering-construction (AEC) industry. In order to use BIM properly, a careful examination of the criteria of BIM for execution on the project is essential. An attorney who is well versed with BIM contract language should be appointed to evaluate the BIM application process.

There are two commonly used documents focusing on the framework of BIM :-

AGC ConsensusDOCS 301 BIM Addendum - This document is developed by the Associated General Contractors (AGC) of America. This type of document is mainly created to plug the void originated from typical standard form agreements which insufficiently, or can’t fully deal with BIM. This document takes into consideration different segments like definitions, information management, the BIM implementation plan, risk sharing, intellectual property rights, and collaboration.

AIA E202-2008 Building Information Modeling Protocol - This document is developed by the American Institute of Architects (AIA). The document aimed at creating an outline for establishing model content, model handling, and model element responsibility.

The above two documents are very effective in communicating & controlling the risk assignment concerning with BIM implementation.

BIM with Risk Management

The parties involved in the project should initially make a decision on the purpose of the model. Once it has been settled, determination the risks for each party become easier.

Before applying BIM in a project, design professionals must highlight some fundamental risk management ideas to find out the legitimacy of BIM. Some of those considerations are as follows :-

BIM involves new business models, hardware, software, and human capital. The costs and risks may relate with the hardware and software investments. BIM is a multifaceted design tool and a thorough understanding of the software is necessary to efficiently deal with and assure design liability.

In order to drive a BIM model there should be enough control and understanding of the technology towards controlling it’s unpredictability and blurred lines of right and responsibility. Project managers should be trained in every phases of the BIM platform

Every organization will have to be conscious of several technical challenges that generate risk in order that it may employ mitigation measures. These types of technical issues may range from interoperability, software limitations, and file storage and transfer limitations. 

There should be proper BIM related service agreements authorized by owners, design professionals, and their legal counsel.

To reap the prospective BIM benefits the risks and information should be allocated equally between the design-construction team as well as the owner, designer, contractor, subcontractors, and suppliers.

Designers must be careful at the time of generating the model with the intention that the Building Information Model they utilize is not restricted to a solitary source, if not an owner purposely ask for it.

Software manufacturers should be cautious toward over-promise or certification of the competence of their products which facilitates design professionals, project owners & others team members associated with the project to easily access to the BIM. All parties must perform mutually to build up new contract forms useful for addressing, allocating, and distributing risk impartially in a clear way.

Design changes in a BIM model may result in enhancing the risk of design and range of services. Information along with design elements is provided into the BIM database and the database communicates elements of a building design. So if a change happens to one phase of the design all interrelated designs consequently are reconfigured. The push for applying BIM’s flexibility to create change upon change right equal to and together with bidding and construction will have to be uncompromisingly controlled and persistently restrained. Although make alteration in BIM is simple, but budgets and design-construction schedules are not as flexible.

Design professionals have to face several quarries while finalizing their design documents. These quarries may range from - What control over the design is to be surrendered to the software providers, contractors, subcontractors, manufacturers, and suppliers? Where should be the line involving the designer-of-record and the other entities contributing input to the model? Should the designer-of-record express his/her control over the design without having BIM expertise? Exclusive of sufficient supervision, is BIM close to the risks concerning off shore outsourcing?

BIM touts its ability to eliminate design conflicts, reduce errors, and limit omissions. But a question remains – will the use of BIM raise the standard of care? Will design professionals using BIM be held to a standard of care equal to perfection or something very close to it? It will be a long while before there is case law addressing these questions. In the short term, designers need to be proactive in defining and reinforcing the concept that the standard of care for BIM-delivered projects as being the same as the standard of care for conventionally-delivered designs.

The BIM users should have sufficient technical and managerial skills toward managing access to all the “pieces and parts, revising & tracking model changes for successfully control model inputs and outputs.

Design professionals while delivering BIM-related information to Consultants, contractors, suppliers, and subcontractors, should necessitate an executed disclaimer like those presently utilized together with providing CADD files.

The risks may also be connected with working across software boundaries in creating design-construction software work.

Design professionals find it difficult to handle the design process for sufficient detailing and quality assurance/control activities. If any construction document is issued from a BIM model not highlighting detail and quality reviews properly, may lead to budget and schedule failures. So designers should assign the essential resources to get rid of the problems.

Some exclusive Projects in recent year in which BIM was successfully implemented for completion of the projects

INOVA Fair Oaks Hospital's New Medical Office Building IV

Building Information Modeling (BIM) technology will have to be utilized for INOVA Fair Oaks Hospital Medical Office Building IV located in Fairfax, Virginia. BIM will be applied to pursue LEED ® Silver certification. Suffolk Construction Mid-Atlantic will work as the contractor for the entire hospital building.

INOVA Fair Oaks Medical Office Building IV is a four storied building containing total area of 115,000 GSF and a below grade level designed and erected for a future radiation / oncology imaging suite with two linear accelerator (LINAC) vaults. The project also comprise of a new campus entrance on Rugby Road; site clearing and construction of supplementary surface parking; setting up of site lighting and traffic signals; and the essential site improvements needed for the new medical office building. 

Historic Hinman Research Building

BIM was utilized for restoration, rehabilitation, and adaptive reuse of the historic Hinman Research Building containing an area of 35,000-square-foot. The total project cost was $9.5 million. The Beck Group acted as construction manager of the project.

BIM was successfully applied to create collaboration among the architectural team and the construction manager. The construction manager (Beck group) transferred the architect’s BIM model to a construction-level BIM model which integrated laser scans of the space to complete the project design maintaining the construction budget and schedule. 
Additionally, Beck group also generated intelligent models to maintain the design, fabrication, and installation of architectural millwork. Beck also offered an absolute model of the building along with facility management functionality to examine the building’s performance over its life cycle.
State Route 99 Tunnel projects
In another case BIM was successfully implemented for collaboration, information sharing. This was a State Route 99 tunnel project in Seattle.  State Route 99 Tunnel is an exceptionally multifaceted project involving civil engineering, structures, architectural elements, mechanical & electrical systems, and traffic management. The project value was $1.35 billion. HNTB served as the designer for the State Route 99 Tunnel project. HNTB utilized an exclusive BIM tool known as Tekla BIMsight for construction collaboration. Tekla BIM sight was applied to combine models from several regulations, evaluate those models with smooth navigation features and capture areas of interest. Tekla BIMsight also facilitated the design team to analyze comprehensive project elements as a whole and locate design and coordination problems connecting each discipline.    
In BIM collaboration, HNTB applied Tekla BIMsight in weekly all-discipline coordination meetings to talk about the two buildings, cut and cover areas, and the tunnel with the sub-consultants, architects, and engineers. HNTB and project participants got the ability to observe clashes and prospective design changes as all the discipline models were loaded into Tekla BIMsight. 

Collaborative model based workflow for Canada's new National Music Centre.
A stunning architectural design was developed for National Music Centre situated across from the Stampede Grounds in Calgary's East Village neighborhood. The project area was 135,000-square-foot music center and cost was $132 million.
The project includes a 300-seat performance space, an interactive music education center, a recording studio, and a broadcast center.

The project contains complex geometries and the concerned architect utilizes Rhino3D, a well accepted architectural modeling program to model the structure. There were some problems regarding the scale of the project, complex architecture and mix of materials.

To overcome the problem the architect has to apply Scia Engineer, a new type of integrated structural design software facilitating engineers plug into today's 3D workflows. Scia Engineer can easily analyze the entire structure by using Rhino3D model into analysis.
From Rhino3D, a VRML (virtual reality modeling language) model can be exported. VRML is a general 3D exchange format for surface and solids modeling programs. It is compatible with ArchiCAD, Sketchup, Solidworks and Vectorworks etc. The VRML model was then imported into Scia Engineer. While importing the VRML model, the Scia Engineer can be used to convert the VRML geometry into 1D or 2D members automatically or convey the model in as reference geometry. Due to several doubly curved shell elements in the design, the model was brought in as a reference model. The concerned structural engineers got the ability to aply the tools in Scia Engineer's BIM toolbox to trace around and convert the Rhino3D model into a appropriate analytical model to available for loading and analysis.

Assotech Blith Projects in Sector 99, Gurgaon

This project was from India. Assotech Limited worked as a developer to make a new housing project, Assotech Blith, in Sector 99, Gurgaon. The project included 12 acres of land containing 586-apartment and located at upcoming 150 Meters wide NPR (Dwarka expressway) in Gurgaon. The project cost was Rs500 crore. In this project BIM was applied for creating the pre-construction three dimensional virtual construction model co-coordinating all the structural architectural and services design elements to get rid of any clashes in the design prior to the compleltion of the project on the ground.  This leads to accurate co-ordination and zero inaccuracies in design. The project was constructed on BIM and LEAN technologies.
