- 3D Model-Based Collaboration in Design Development and Construction of Complex Shaped BuildingsKu, Kihong; Pollalis, Spiro N.; Fischer, Martin A.; Shelden, Dennis R. (2008)The successful implementation of complex-shaped buildings within feasible time and budget limits, has brought attention to the potential of computer-aided design and manufacturing technologies (CAD/CAM), Building Information Modeling (BIM), and the need for integrated practice. At the core of an integrated practice vision lies the intimate collaboration between the design team and construction team and a digital three-dimensional model, often with parametric and intelligent characteristics. With the shift from two-dimensional (2D) paper-based representations to threedimensional (3D) geometric representations in building information models (BIM), architects and engineers have streamlined 'inner' design team communication and collaboration. However, practice conventions have posed significant challenges when attempting to collaborate on the designer's 3D model with the 'external' design team-involving the architect (or engineer)-of-record, and contractor, construction manager or fabricator, etc. Focusing on the execution of complex-shaped buildings, the objective of this paper is to illustrate varying collaborative approaches to understand how design teams use 3D models to control geometry. The authors attempt to provide specific responses to the following questions: What are the issues when collaborating on 3D models? What are the mechanisms that design teams adopt to surpass practice conventions? The findings from three case studies suggest that collaboration methodologies on 3D models differ with the architects' approaches to geometry control. The authors will demonstrate that successful model-based collaboration occurs either on a contractual or non-contractual model issued by the architect.
- A 6-Step Systematic Process for Model-Based Facility Data DeliveryThabet, Walid; Lucas, Jason D. (2017)The use of BIM for FM by owners is growing, yet there are challenges that exist because of the need for customized data standards to fit each owner's need. This research examines the development of a model-based approach for capturing and handing over facility data. Previously completed research consists of a spread-sheet based documentation method for capturing identified facility-related information to support an owner's operation and maintenance of educational facilities. An approach was developed and piloted to validate a process that utilized milestone information submissions for documenting appropriate information throughout the design and construction of a facility using a spreadsheet based approach with direct input into the Computerized Maintenance Management System (CMMS). Using a pilot project approach, this paper builds on the spreadsheet based approach by identifying how the facility information could be captured throughout the project using a model based approach. A six-step systematic process is defined for BIM-FM integration to capture facility data and integrate the information into a CMMS. Various challenges and considerations to capture and deliver facility data are discussed. The paper also discusses the need for further validation of the proposed process and summarises ongoing study to test the proposed approaches using a second pilot project.
- Contractual Standards for Enhanced Geometry Control in Model-Based CollaborationKu, Kihong; Pollalis, Spiro N. (2009)This paper discusses the definition of contractual standards for ICT-enabled business models and value-driven business models, focusing on model-based collaboration for enhanced geometry control. While a growing number of highly publicized international complex-shaped buildings have demonstrated the usage of three-dimensional (3D) modeling as the primary means for geometric representation, the authors have observed a lack of contractual standards around the 3D model. Process complexities that are deeply embedded in practice conventions, along with legal constraints and risk allocation, pose challenges to the establishment of standard agreements. As a result, individual project teams often struggle to define and find adequate design agreements to facilitate effective control of geometry around the 3D model. Ineffective geometry control may result in schedule delays when project participants disagree on the representation of the 3D model, or even change the original design intent, eroding the integrity of the design. Thus, the proliferation of 3D tools and owner demand for complex-shaped buildings creates a great need for standard design agreements over the control of the architect's geometric 3D model, in order to define control and authority, as well as a mechanism to access and verify the validity of the 3D geometry. The study presents an in-depth review and analysis of (1) the existing body of literature on effective geometry control; (2) case study examples of geometry control as a project metric; (3) an analysis of sample contract terms and the effect on geometry control approaches; and (4) recommendations for effective geometry control contract terms, processes, and strategies for owner-architect and owner-designer standard agreements. The paper's principal value lies in (1) its definition of geometry control as a performance metric and (2) its guideline for standard contract terms to facilitate effective geometry control via design agreements. The results will complement existing industry efforts by owner organizations such as the Construction Users Roundtable and design organizations such as the American Institute of Architects.
- Linking life cycle BIM data to a facility management system using Revit DynamoThabet, Walid; Lucas, Jason; Srinivasan, Sai (Sciendo, 2022-01-01)Facility management (FM) requires multidisciplinary activities, and thus has extensive information requirements. Much of that information is created during the design, construction, and commissioning phases of a project. Providing the owner of a facility with usable life cycle asset information after construction has been a challenge to the industry. Traditional methods of manually inputting data into FM systems are time consuming and error prone. Various automated approaches and workflows continue to be developed to respond to specific owner needs. This research developed a unique workflow that uses Dynamo within Revit to automatically extract asset management data from the model and export the data to a proprietary format required by the facility owner. The formatted spreadsheet allows for direct linking of the data to the owner's FM system, hence eliminating time wasted in manual data entry and avoiding missing any maintenance cycles that would result if the FM system is not populated with critical information in a timely manner. This article utilizes a case study approach to demonstrate this novel Dynamo workflow. The required case study asset data identified and captured include asset groups, their properties and attributes, and corresponding metadata. A basic three-dimensional representation of the facility and all its equipment are modeled in Revit and asset data are input to corresponding model elements. This article also describes the complexity of the owner's proprietary information needs and the resulting automated workflow that extracts and exports data from Revit into an Excel format that can directly link into the FM system.
