Where are we going? What can we look forward to in the future Introduced by Autodesk in 2002, the term building information modeling (BIM) refers to the creation and use of coordinated, consistent, computable information about a building project in design—information used for design decision making, production of high-quality construction documents, predicting performance, cost-estimating and construction planning, and, eventually, for managing and operating the facility. I define the BIM “ as all the information about a project within its property lines to the center of the earth and infinitely to the sky; from its inception thru construction and use until its final decommission and elimination”. The basis of the BIM

Letterman Digital Arts Center View By View Mieczyslaw (Mitch) Boryslawski is the Founder of View By View, Inc., which he propelled from its initial role as an architectural visualization service bureau in 1990 to its current status as one of the first companies to have taken BIM through the entire construction process. Mitch was born in Poland, and educated in Europe, South Africa and the USA in architecture and construction project management. He is a frequent speaker on digital architecture and BIM, has been involved in international architectural competitions for the last 30 years, and has won several awards including the 2005 "Digie" Award for the Best Use of Automation-Architectural Design.

Where we are going? According to the survey of 3,000 architecture firms in the latest, “The Business of Architecture” survey by the American Institute of Architects, (in the AIA Architect newsletter), a little more than 16 percent of firms reported having acquired BIM software and about 10 percent reported using it for billable work. Of the firms that do have BIM software, most use it for design development (91 percent), schematic design (86 percent), and construction documentation (81 percent). Among the firms having it, nearly two thirds are using their BIM software for billable work, ranging from 60 percent among sole practitioners to 86 percent among 100-plus- employee firms.
Note: This survey was done a year ago, so the figures may have changed a little. Construction Modeling

Facilities Management Industry Foundation Classes IFC2x Edition 2 International Alliance for Interoperability In December of 2003, the General Services Administration/Public Building Service issued internal guidance to its regional staff stressing the need for on-time, under-budget project deliveries in the capital construction program. It determined that new and emerging technologies such as 3D/4D and building information models (BIM) have the potential to dramatically improve the outcome of projects and enhance customer satisfaction.
As a result of this guidance, GSA/PBS recently issued a critically important request to all firms in the design, construction, facility management, and real property industries for information on the use of IFC-based BIM technology. According to GSA/PBS, the information will be “used to assist the government in establishing potential sources in the marketplace with knowledge and experience in the use and practices of this state-of-the-art technology.” Deadline for all submissions is March 15, 2005. GSA has indicated that, beginning in July, the delivery of IFC-based BIM will be required for the preliminary design phase of all new fiscal year 2006 projects.
Listed below are just some of the IES tools available
For thermal analysis:
ApacheCalc: provides heat loss and heat gain calculations based on the CIBSE Guide ApacheLoads: calculates design heating and cooling loads based on the ASHRAE Heat Balance Methods ApacheSim: an advanced, dynamic thermal simulation application which can also perform carbon emissions calculations ApacheHVAC: simulates HVAC plant and control systems MacroFlo: enables you to simulate natural ventilation and mixed mode systems
For lighting analysis:
RadianceIES: a detailed 3D simulation tool designed to predict daylight and electric light levels, and the appearance of a space prior to construction. FlucsPro: calculates the number of luminaires required in a room, and analyses light levels for defined lighting schemes. FlucsDL: performs lighting design calculations to determine the day-lighting levels in a room. It allows you to perform point-by- point lighting analyses to give light level values within a room. LightPro: allows you to place luminaires anywhere in a room for subsequent analysis using FlucsPro, or a detailed simulation using RadianceIES.
For solar analysis:
SunCast: generates visual, graphical and numerical information that can be used to explain to colleagues, clients and planning authorities how the sun impacts on and inside the building, and on the site.
For Evacuation and people movement analysis:
Simulex: enables you to simulate the evacuation of a building and evaluate alternative escape routes. Lisi : enables you to design and simulate lift options. IES http://www.e-specs.com/

In its collaboration with McGraw-Hill Construction, CADalytic Media is providing an easy-to-use Sweet's-for-CAD. ADS – Architectural Data Systems http://architecturaldatasystems.com/
ADSymphony This is an excellent and unique solution that automatically integrates 3D content from manufactures into your AutoCAD, AutoCAD Architecture, or Revit projects. Best of all, it is free for one named user, with a minimal cost for additional users (several users in the same office can access the system for free, but not at the same time). To use ADSymphony, you simply log on to the ADS website. You then use AutoCAD, AutoCAD Architecture, or Revit as you would normally, placing generic content such as doors, windows, etc into you project. You then go out to the ADS website from within your program, select the manufacturer’s catalog and content, and your generic content is changed to the manufacturer’s content. For example, in AutoCAD Architecture, the specs are automatically created, the schedules are made, and the sizes of the windows automatically changed. In AutoCAD Architecture, you must change the type and shape of the windows yourself (the sixes and attributes will be correct, but a double hung window will not change automatically to a hopper style). In Revit Architecture, everything is automatic; the content change to the actual manufacturer’s content as well as creating the schedule and specs. There is a growing library of over 900 product catalogs, complete with 3D content, and more being created all the time.

http://www.uscost.com PARAMETRIC COST MODELS Success Estimator’s powerful modeling capabilities allow companies to use their own specific legacy data and engineering algorithms to develop meaningful, accurate cost models. As more information becomes available, information in the model can be adjusted at a very detailed level, taking the estimate from feasibility to 100% completion.
CENTRALIZED COST DATA Use R.S. Means, Richardsons and your company’s legacy cost data individually or in combination on any estimate thereby insuring the most accurate and up-to-date information is being used.
ASSEMBLIES Generate estimates faster than ever before by utilizing one of the many R.S. Means Assemblies libraries or build unique custom assemblies with your company’s legacy cost information.
ESTIMATE ANALYSIS Compare actuals to estimates, variances across multiple projects or cost trends on commodities by using one of the numerous macros shipped as part of Success Estimator. Use the Success Estimator Visual Basic programming language to write custom macros directly in the base application. DesignEst Pro
DesignEst Pro is integrated with Revit Architecture 2008. Utilizing the Revit API, they have given the user the ability to map their Revit Elements and their respective properties to the corresponding objects and properties in a WinEst cost estimating database.
The basic elements that come standard with Revit are already mapped to the corresponding objects in two WinEst cost databases, the WinEst Commercial CAD Database and the R.S. Means Building Construction Cost Database w/Assemblies. A hallmark of DesignEst Pro is the user’s ability to map their custom Revit elements to the corresponding objects in their WinEst database. The audit capabilities allow the cost estimate to be continually updated to reflect changes in the design. DesignEst Pro is targeted at 3 primary markets: 1. Architects and their need to produce budget constrained designs. 2. Design Build Firms and their need to more efficiently produce both conceptual and detailed cost estimates, and more quickly turnaround cost estimates for change orders 3. Independent design companies and independent builders desiring enhanced collaboration to secure a specific project, or in response to a large owner that is dictating a more efficient collaborative process.
