Abstract: In 2008, AACE International members interested in advancing the state of estimating in building information modeling (BIM) began collaborating with members from the American Society of Professional Estimators (ASPE), and members from the Royal Institute of Chartered Surveyors (RICS), to define the information exchange requirements for cost estimating in BIM. The information exchange requirements are the basis for an information delivery manual (IDM) required from the designer to the estimator. This is a unique and important effort for estimators to take an active role in developing a future national standard. Without defined requirements for information exchange, estimators run the risk of receiving a BIM that is populated with inaccurate or incomplete project information. The ultimate goal of the collaborative effort, reported in this paper, is to produce a ballot item for submission to the National BIM Standard (NBIMS). This paper reports on the process development to date and the future plan for the collaborative effort. (BIM-837) Building Information Modeling - The Cost Estimator's Role
Primary Author: Mr Edward Keane CCC Project Management Services Inc.
Abstract: Building Information Modeling is a term representing a new process or approach that is being widely implemented in the architecture, engineering and construction (AEC) industry. If one works in this industry and has not yet heard the term, it is reasonable to expect it will not be the case much longer. The adoption of this approach to designing and managing projects is catching on at a phenomenal pace in the US and in Europe. The firms that have been early adopters of BIM are realizing its benefits and enjoying a competitive advantage as they work to secure and perform new projects in a much more efficient manner, from the conceptual design stage through project completion, and the operation and maintenance of the building. BIM continues to overcome the initial hesitancy among architects, designers, engineers, contractors and owners, by proving itself to be a powerful data management system and time saver. BIM is in its early stages of development and the tools that support BIM are being improved each year. The AEC industry will continue to reap the rewards as the tools and processes of BIM are fine-tuned. (BIM-846) Application of BIM and GIS in Class 1-5 Cost Estimates

Abstract: Building Information Modeling (BIM) and Geographic Information Systems (GIS), based on open standards, transform the way the cost engineering industry works and will work in the future. This paper presents four examples to demonstrate how BIM and GIS can be applied to all classes of estimates. The first example includes a building, in conjunction with GIS, to model and optimize a real estate development project to produce a Class 5 estimate. The second example demonstrates how architectural BIM sketches can be combined with smart assemblies that use conceptual cost data to produce a Class 4 estimate. The third example uses a basic design BIM model, combined with commercial assemblies, to produce a Class 3 estimate. The fourth example uses a detailed Industry Foundation Class (IFC) model for a quantity takeoff, and combined with commercial databases, generates a Class 2 estimate. The same BIM model is used as a basis for creating and managing quotes from suppliers and subcontractors and developing definite Class 1 estimates. The resource and cost loaded detailed BIM model is examined through value engineering and analysis as an alternate method for presenting proposals. (BIM-918) RFID and BIM for Automated Progress Reporting
Primary Author: Mr Ali Montaser Concordia University
Co-author(s): Dr Osama El Sayed Moselhi P Eng Concordia University
Abstract: This paper presents a near-real-time automated method for data acquisition and progress reporting of construction operations indoor. The developed method utilizes the joint use of low cost passive Radio Frequency Identification (RFID) tags, RFID mobile reader, tablet PC, project schedule and Building Information Modeling (BIM). RFID is used for indoor zone identification where GPS cannot technically be used. By integrating project schedule and BIM, a 4D model is generated to simulate a planned construction sequence. Visualization of zone activities, in near-real-time, via the planned 4D model is achieved through assigning a zone to the user from the received nearest RFID tag signals. Meanwhile, automated data acquisition from each zone will generate numerous data in formats such as images, notes and video clips, which is then compared to the planned 4D model to generate an automated progress report. This will enhance traditional progress reporting procedures and makes it more objective and less time consuming. The developed method is applied to a construction project in Montreal area to demonstrate its use. (BIM-995) 4D Scheduling Using Delmia® and Microsoft Project® on Hydroelectric Construction Projects

Abstract: A major Canadian utility company has recently added the dimension of time (4D) to its scheduling on four new facilities and rehabilitation hydroelectric projects using Delmia®. As-planned project schedule evolution is viewed on a Gantt chart, while progress is shown on the project's 3D mock-up. Each mock-up piece is matched to distinct schedule activities and according to project complexity and user type, a summary or detailed level is selected for simulation. With this new technology, now schedulers, estimators, engineers and managers can enhance internal standards by building quick-thinking schedules, reviewing project scenarios, providing insight on constructability, methods and optimizations, preventing safety hazards, choosing better materials and predicting costs in a more accurate fashion. 4D scheduling facilitates earlier knowledge about interfaces, existing conditions, access and material handling, reduces requests for information, accelerates change process and enables easier communications between stakeholders from pre-feasibility till end of construction phase.
