Framework Development For Construction Safety Visualization, Kishor Shrestha

UNLV Theses, Dissertations, Professional Papers, and Capstones

Throughout the history of the construction industry, many fatalities and injuries have occurred in construction sites. One of the major causes of accidents is unsafe site conditions; basically, this is due to inadequate supervision. To improve upon the traditional supervision approach, this study proposes a `Framework Development for Construction Safety Visualization' approach. In addition to this, a computer vision Edge Detection Algorithm was developed and tested to convert construction site still images into edges of the objects in the images. The framework development of this study uses computer vision, robot vision, image compression, pattern recognition, internet transmission, network communication, and ...


A Composite Structural Steel And Prestressed Concrete Beam For Building Floor Systems, Nathan deWit 2012 University of Nebraska-Lincoln

A Composite Structural Steel And Prestressed Concrete Beam For Building Floor Systems, Nathan Dewit

Architectural Engineering -- Dissertations and Student Research

Precast prestressed concrete beams, such as rectangular and inverted tee beam, currently used in residential and commercial buildings are deep, heavy, and limited to span-to-depth ratios of 15. The research proposes a composite structural steel and prestressed concrete beam that is shallow, light, easy to produce and erect, and able to achieve a span-to-depth ratio of 24. The proposed beam is designed to be used with precast columns, hollow-core planks, and a cast-in-place topping to create a moment-resisting floor system that minimizes the need for shear walls. The goal of this system is to eliminate as many of the limitations ...

A Model Of Housing Design And Neighborhood Planning In Abuja - Nigeria, Ekanem Amba

Master of Technology Management Plan II Graduate Projects

The need for shelter is one of the most important necessities for mankind after sustenance. Over the years, the term ‘shelter’ has undergone series of modification either in shape, space, location or the materials used in constructing them but one thing remains the same; the need for a roof over one’s head is as vital to survival as time in itself.


Impact Of The Capital Market Collapse On Public-Private Partnership Infrastructure Projects, Michael Regan, Jim Smith, Peter Love 2012 Bond University

Impact Of The Capital Market Collapse On Public-Private Partnership Infrastructure Projects, Michael Regan, Jim Smith, Peter Love

Michael Regan

The collapse of capital markets is having an impact of the funding arrangements for economic and social infrastructure projects in Australia. Bearing this in mind, this paper seeks to examine whether the current volatility and uncertainty in capital markets in Australia affects the feasibility of privately financed infrastructure and specifically the public-private partnership PPP method of procurement. This paper examines the role and dependency that capital markets play in funding PPPs, current market conditions, and how they will affect PPP viability. In addition, alternative funding and procurement mechanisms that can be used for short- and medium-term infrastructure deliveries are presented.


An Overview Of Component Unit Pricing Theory, David Cattell 2012 Bond University

An Overview Of Component Unit Pricing Theory, David Cattell

David Cattell

Component unit pricing (CUP) theory presents a fresh approach to item pricing, described as the process of distributing the overall price among its constituent component items. This theory provides explanation and proof that different distributions of mark-up among the items of a project produce different levels of reward for contractors, while exposing them to different degrees of risk. The theory describes the three identified sources of these rewards, namely those of improved cash flow, escalation in compensation and valuations of likely variations. In addition, it also provides the first explanation of the three risks involved, namely the risk of ‘rejection ...

The Economic Case For Early Adoption Of Facilities Management, Barry Mcauley, Alan V. Hore, Roger West, John Wall

Conference papers

The construction industry in Ireland has been the sector hit the hardest during the recession with a potential return to output volumes of the mid-1990s. In order to compete within this struggling construction sector the traditional way of doing business must be re-engineered. One of the ways to achieve this is by introducing the Facilities Management (FM) process much earlier into the construction process, in order to maximize long term sustainability, and above all whole life construction costs. This paper will focus on a recently constructed sports clinic in Dublin, in which an aggressive programme was introduced around energy management ...


The Bonds That Tie: Will A Performance Bond Require That A Surety Deliver A Certified Green Building?, Darren Prum, Lorilee Medders 2012 The Florida State University

The Bonds That Tie: Will A Performance Bond Require That A Surety Deliver A Certified Green Building?, Darren Prum, Lorilee Medders

Darren A. Prum

In 2006, the city of Washington, D. C. passed landmark legislation that introduced green building requirements for various types of structures into the jurisdiction over a five-year period. A noteworthy aspect of the legislation directed construction projects within the district to purchase green performance bonds up to $3 million to guard against a privately owned project’s failure to meet its green building aspirations. In essence, this law placed the burden of guaranteeing compliance with the government’s policy upon the contractors and sureties of a green building project.

Following the passage of this act, confusion amongst the construction industry ...

The new shelter should incorporate improved natural lighting and ventilation, adequate space for laundry facilities and more space for the animals' living and bathing needs. The design should consider how to prevent dogs from barking and disturbing one another while in the kennels. Increased storage is necessary for the animal shelter to contain the food and living amenities for the incoming animals.


Application Of Drum-Buffer-Rope Methodology In Scheduling Of Healthcare System, Arefeh Mohammadi, Emmanuel S. Eneyo 2012 University of Nebraska-Lincoln

Application Of Drum-Buffer-Rope Methodology In Scheduling Of Healthcare System, Arefeh Mohammadi, Emmanuel S. Eneyo

Architectural Engineering -- Faculty Publications

Theory of constraints (TOC) is a management philosophy that seeks to increase throughput (efficiency or performance) of the system by identifying those processes that are constraining the system bottlenecks. There have been very few profound studies of TOC in health care systems. In order to fill this gap, this study was conducted to determine how healthcare systems are utilizing components of TOC to schedule operations and what results are being obtained. This is done by using a patient flow model for a radiotherapy section of a hospital. The drum-buffer-rope (DBR) was used as the methodology for scheduling this flow. Successful ...


Effects Of Roof Pitch On Air Flow And Heating Load Of Sealed And Vented Attics For Gable-Roof Residential Buildings, Shimin Wang, Zhigang Shen 2012 University of Nebraska - Lincoln

Effects Of Roof Pitch On Air Flow And Heating Load Of Sealed And Vented Attics For Gable-Roof Residential Buildings, Shimin Wang, Zhigang Shen

Architectural Engineering -- Faculty Publications

Pitch value is an important consideration in residential gable roof design and construction. However, how roof pitch, coupled with air flows in attic space, affects the energy performance of building attics has been barely investigated. In this paper, a 2D unsteady computational fluid dynamics (CFD) model is employed to investigate the effects of roof pitch on air flow and heating load of both sealed and vented attics for gable-roof residential buildings. The simulation results show that air flow in the sealed attics is steady and asymmetric, while that in the vented attics is a combination of an essentially symmetric base ...

Effects Of Inclusion Shapes Within Rigid Porous Materials On Acoustic Performance, Hyun Hong, Siu-Kit Lau 2012 University of Nebraska-Lincoln

Effects Of Inclusion Shapes Within Rigid Porous Materials On Acoustic Performance, Hyun Hong, Siu-Kit Lau

Architectural Engineering -- Faculty Publications

The present study investigates the influence of various shapes of inclusions having same volume embedded in a porous rigid material. Previous studies showed improvement of the broadband sound absorption with particular shapes of inclusions. However, different volumes of the inclusions have been considered; therefore, the bulk densities are not the same for comparison. The present study extends the investigations of inclusions in porous materials with same volume (or bulk density) to eliminate the influence by the change of bulk density. The effects of shape will be discussed. Finite element modeling will be used for this study. Total four different shapes ...


Impacts Of Ventilation Ratio And Vent Balance On Cooling Load And Air Flow Of Naturally Ventilated Attics, Shimin Wang, Zhigang Shen 2012 University of Nebraska - Lincoln

Impacts Of Ventilation Ratio And Vent Balance On Cooling Load And Air Flow Of Naturally Ventilated Attics, Shimin Wang, Zhigang Shen

Architectural Engineering -- Faculty Publications

The impacts of ventilation ratio and vent balance on cooling load and air flow of naturally ventilated attics are studied in this paper using an unsteady computational fluid dynamics (CFD) model. Buoyancy-driven turbulent ventilations in attics of gable-roof residential buildings are simulated for typical summer conditions. Ventilation ratios from 1/400 to 1/25 combined with both balanced and unbalanced vent configurations are investigated. The modeling results show that the air flows in the attics are steady and exhibit a general streamline pattern that is qualitatively insensitive to the variations in ventilation ratio and vent configuration. The predicted temperature fields ...


Development And Evaluation Of A Simplified Modeling Approach For Hydraulic Systems, Yuebin Yu, Vivian Loftness, Daihong Yu, Yan Lu, Volker Hartkopf 2012 Carnegie Mellon University

Development And Evaluation Of A Simplified Modeling Approach For Hydraulic Systems, Yuebin Yu, Vivian Loftness, Daihong Yu, Yan Lu, Volker Hartkopf

Architectural Engineering -- Faculty Publications

This paper presents how a hydraulic system can be properly modeled for hydraulic balancing, knowledge of flow distribution, coupled simulation, and evaluation of control, etc. It focuses on water-based heating and cooling systems, which generally have high energy efficiency in design but could perform poorly in reality due to the undersensing condition and strong thermal-hydraulic coupling. The study introduces the motivation, presents the simplified modeling methodology, and illustrates the model and simulating structure. A preliminary evaluation of the method is conducted with two simple simulations. The proposed “node-branch-state” modeling approach could be easily modified, expanded and integrated into a detailed ...
