Linking Effective Whole Life Cycle Cost Data To Parametric Building Information Models Using Bim Technologies, Dermot Kehily, Trevor Woods, Fiacra P. Mcdonnell

Conference papers

Abstract ̶ This paper demonstrates the capabilities of BIM (Building Information Modeling) in leveraging Whole Life Cycle Cost (WLCC) data requirements to perform WLCC calculations and produce WLLC estimates. The research determines the extent to which WLCC data, such as time, interest rates, escalation rates and real costs can be attached to parametric BIM data to be used effectively to create speedier and more accurate real-time WLLC analysis. Without incorporating WLCC data in the BIM, a complete picture of a construction project’s WLCC cannot be formed from the default outputs of the model. BIM 5D applications such as CostX utilise …

Compression Testing And Failure Modes Of Steel-Concrete Composite (Sc) Structures For Nuclear Containment, Patrick Michael Wanamaker, Amit H. Varma

The Summer Undergraduate Research Fellowship (SURF) Symposium

Although being able to provide much cleaner power than burning coal and other fossil fuels, nuclear power plants are still a tough sell to the general public due to their history of being spontaneously dangerous. The containment structures surrounding these nuclear plants, however, can play a huge role in reducing the risks associated with them. Relatively new designs for these containment assemblies, known as SC (steel-concrete composite) structures, aim to increase the strength and durability of the containment facilities while keeping costs down. By varying the spacing between shear studs, the ratio of concrete to steel, and the ratio of …

Decorative Ferrocement Elements, Letitia Nadasan, Traian Onet, Ana Ioana Petean, Marian Sabau

Marian Sabau

Ferrocement has the versatility that can be 'sculptured' or shaped into numerous fascinating structures and objects for very wide applications. The exposure of this technology to engineers in general is rather minimal in Romania and many are skeptical about it. The potential is not exploited for it being unconventional in nature. Its ability to compete or use as a cheaper alternative and yet a promising technology in ensuring improved living standard and environmental quality must not be neglected. The paper discusses about the applicability of ferrocement in the Romanian scene with respect to recreation and home use. The ferrocement elements …

Project Complexity Mapping In Five Dimensions For Complex Transportation Projects, Douglas D. Gransberg, Jennifer S. Shane, Carla Lopez Del Puerto

Douglas D. Gransberg

Traditional three-dimensional project management theory is based on optimizing the cost-schedule-technical dimensions. Recent studies in the United Kingdom, Canada, and Australia have shown that the current project management body of knowledge may not be adequate to address interrelated and dependent variables encountered on complex projects. This paper reports the findings of an international research team’s detailed study of eighteen complex projects, which confirms the findings of the previous research and proposes a framework upon which a complex transportation project’s scope of work can be better conceptualized and a methodology to graphically display a project’s complexity in order to better understand …

Using Purchasing Power Parity To Assess Construction Productivity, Rick Best

Rick Best

For many reasons comparing construction productivity between countries is a difficult task. One key problem is that of converting construction costs to a common currency. This problem can be overcome relatively simply by using a basket of construction materials and labour, termed a BLOC (Basket of Locally Obtained Commodities), as a unit of construction cost. Average BLOC costs in each location are calculated from data obtained from a number of sources (quantity surveyors, estimators). Typical building costs obtained from published construction cost data are expressed in BLOC equivalents. Lower BLOC equivalents represent higher productivity as other inputs (largely materials) are …

Predicting Building Energy Performance: Leveraging Bim Content For Energy Efficient Buildings, Eddie Villanueva Aquino

Master's Theses

Reducing and managing the environmental impacts of building structures has become a priority of building stakeholders and within the architecture, engineering and construction (AEC) community; although, conflicting approaches and methods to combat the issues are present. For example, green building standards are widespread throughout the world; however each one has its own characteristics and consequently its own specific requirements. While all have proven to be effective rating systems and have similar requirements, the distinguishing characteristic that separates them is their treatment of performance and prescriptive metrics. The feature they all severely lack or currently limit is the inclusion of strict …

Experimental Determination On Bond Strength Of Rebar In Self-Compacting Concrete, Marian Sabau, Traian Onet, Ana Ioana Petean

Marian Sabau

Experimental results of the local bond stress-slip relationship of deformed reinforcing bars embedded in confined self-compacting concrete are presented. A total of 58 pull-out specimens were tested. Each one of these specimens simulated the confined region of a beam-column joint. The main analyzed parameters were the concrete type, the confining reinforcement, the reinforcement bar diameter, the embedded length of bars. The results showed that in order to ensure that the bond failure is caused by pull-out, a restraining reinforcement must be provided. The paper also presents a comparison between self-compacting concrete (SCC) and normally vibrated concrete (NVC).

Developing A Standard Approach To The Value Engineering Process For The Civil Engineering Industry: A Theoretical, Case Study And Industry Perspective., Charles Anthony Mitchell

Conference papers

The original Value Engineering process developed in North America in the late 1940‟s, was primarily based on functional analysis. However; the North American Value Engineering process was not adopted in Europe. Instead various mixed methods were assembled under the umbrella term of Value Management. Nowadays there is much debate about what Value Engineering is and how is it defined? This question arises in part due to there being no standard approach in Europe as a whole in undertaking ValueManagement or Value Engineering exercises.With this in mind, Masters level research was undertaken from three perspectives (theory, case study and industry).
