A Visual Approach to Construction Cost Estimating

摘要: A VISUAL APPROACH TO CONSTRUCTION COST ESTIMATING Phuwadol Samphaongoen, B.S. Marquette University, 2010 Construction cost estimating is considered one of the most important and critical phases a construction project. Preparing reliable accurate estimates to help decision makers challenging assignment that estimators face. An estimate not only necessary for proposal preparation but also several project management functions. Despite importance estimating, it has remained very time consuming process. The inefficient part determination amount resources needed This known as quantity takeoff. Quantity takeoff long error-prone process performed manually by estimators. Missing or duplicating work items are among errors can occur during New Parametric CAD software recently attained widespread attention in Architectural, Engineering, (AEC) industry. It represents development use computer-generated models simulate planning, design, operation facility. helps architects, engineers, contractors visualize what be built simulated environment identify potential operational problems. model created from parametric will significantly increase estimator productivity substantially reducing manual performing takeoffs. study presents methodology uses visualization technologies streamline Although this won’t totally automate process, following areas: (1) providing navigable 3D project, (2) simplifying (3) eliminating calculations search data. navigate through model. would provide with tool improve understanding location relationships between elements may simplified using properties geometry information extracted database technology store labor, equipment, material eliminate enables an data stored database. case presented illustrate capabilities developed system.
