A Semantics-Based Approach To Construction Cost Estimating, Mehrdad Niknam Oct 2015

A Semantics-Based Approach To Construction Cost Estimating, Mehrdad Niknam

Dissertations (1934 -)

A construction project requires collaboration of different organizations such as owner, designer, contractor, and resource suppliers. These organizations need to exchange information to improve their teamwork. Understanding the information created in other organizations requires specialized human resources. Construction cost estimating is one of the processes that requires information collected from several sources including a building information model (BIM) created by designers, estimating assembly and work item information maintained by contractors, and construction resource cost information provided by resource suppliers. Currently, it is not easy for computers to integrate the information for construction cost estimating over the Internet. This study discusses …

Aligning Bim And Lean Methodologies Within Capital Works Management Framework In Ireland, Barry Mcauley, Alan Hore, Muiris O'Loingsigh, John Deeney Jun 2014

Aligning Bim And Lean Methodologies Within Capital Works Management Framework In Ireland, Barry Mcauley, Alan Hore, Muiris O'Loingsigh, John Deeney

Conference papers

In 2007, following continued dissatisfaction with the lack of cost certainty on publicly funded projects, the Irish Government introduced the Capital Works Management Framework (CWMF). This framework had stated strategic objectives of achieving greater cost certainty at contract award stage; better value for money at all stages during project delivery and, more efficient end-user delivery. The framework, in particular, sought to rebalance risk, so that there was an optimal transfer of risk to the contracting authority and the contractor through the implementation of fixed price contracts. Coinciding with the introduction of the CWMF, there was significant debate around the introduction …

Current Bim Practices Of Commercial Mep Contractors, Bryan John Kent Jun 2014

Current Bim Practices Of Commercial Mep Contractors, Bryan John Kent

Theses and Dissertations

Building Information Modeling (BIM) use in the contracting industry has grown significantly in recent years. With this change in the construction industry, consensus has not been reached as to what BIM is, who is using it and what they are using it for. The purpose of this research was to determine current BIM practices of US-based commercial MEP contractors. Executive, middle management, and field personnel were interviewed to determine the current BIM practices in their companies. The majority of companies interviewed were using BIM and most were using it on a significant portion of their projects. The majority of MEP …

Best Practices Using Building Information Modeling In Commercial Construction, Simon Beveridge Dec 2012

Best Practices Using Building Information Modeling In Commercial Construction, Simon Beveridge

Theses and Dissertations

There has been an increase in adoption of building information modeling (BIM) by commercial contractors over the past few years but there is not a clear indication of current application or the frequency of each use. This research was undertaken to determine the frequency and best practices of using BIM in commercial construction. Leading commercial contracting firms were contacted and employees were selected to complete a telephone survey that was designed to determine how they are using BIM. It was found that BIM is being used with more frequency on projects, with plans to continue to implement it even further …

A Building Lca Case Study Using Autodesk Ecotect And Bim Model, Endong Wang, Zhigang Shen, Charles Barryman Jan 2011

A Building Lca Case Study Using Autodesk Ecotect And Bim Model, Endong Wang, Zhigang Shen, Charles Barryman

Department of Construction Engineering and Management: Faculty Publications

The main objective of this study is to evaluate the potential of utilizing building information model (BIM) to perform whole building Life Cycle Analysis (LCA). The research question addressed was how life cycle performance of a building was affected quantitatively by design configurations. Life cycle energy consumption and CO2 emission of a university building in the Midwest was calculated using Autodesk® Ecotect and BIM model. The study compared life cycle performance, i.e., CO2 emissions and energy consumptions, among different design configurations, as well as their distributions in the stages of the building’s life time. Sensitivity analysis was performed …

The Use Of Building Information Modeling In Generating Hard Bid Estimates, Peter Samuel Jensen Dec 2010

The Use Of Building Information Modeling In Generating Hard Bid Estimates, Peter Samuel Jensen

Theses and Dissertations

Building Information Modeling has provided many benefits to the architectural, engineering, construction and facilities management communities. Many studies have been done to validate the asserted benefits, including benefits to the field of estimating. The studies on estimating are currently limited to the realm of conceptual estimates, and have only treated detailed estimates in the abstract. The purpose of this study was to determine how BIM was being used by companies in a hard bid, or detailed estimate scenario. The research team used the Deseret Towers housing project at Brigham Young University as the basis for the research. A building information …

Developing A Cloud Integrated Life Cycle Costing Analysis Model Through Bim, Alan Redmond, Alan V. Hore, Roger West Jan 2010

Developing A Cloud Integrated Life Cycle Costing Analysis Model Through Bim, Alan Redmond, Alan V. Hore, Roger West

Conference papers

Advancing interoperability between design team applications has been a major challenge for advocates of open standards. The buildingSmart alliance and Open Geospatial Consortium Inc in the U.S. have developed and implemented an Architecture, Engineering, Construction, Owner Operator, Phase 1 Testbed that streamlines communications between parties at the conceptual design phase to establish an early understanding of the tradeoffs between construction cost and energy efficiency. The results of this Testbed combined with an on-going collaborative R&D project ‘Inpro’ co-funded by the European Commission to identify business and legal issues of Building Information Modeling in construction were used as theoretical propositions underlying …

Quantitative Evaluation Of The Bim-Assisted Construction Detailed Cost Estimates, Zhigang Shen, Raja R. A. Issa Jan 2010

Quantitative Evaluation Of The Bim-Assisted Construction Detailed Cost Estimates, Zhigang Shen, Raja R. A. Issa

Department of Construction Engineering and Management: Faculty Publications

The increased interest in using Building Information Modeling (BIM) in detailed construction cost estimates calls for methodologies to evaluate the effectiveness of BIM-Assisted Detailed Estimating (BADE) tools in generating detailed construction cost estimates. The focus of this study is on developing a quantified evaluation method to measure the impact of these BADE tools. Further, in order to understand the cognitive details of the estimator, this study also tested and evaluated the impact of the visualization factor and the compound impact of the visualization factor and aggregated calculation factor on the construction cost-estimating process. Two types of BADE tools were tested …
