Case study for identification and evaluation of construction innovations: the Hotel Georgia projectAwuni, Roland Chiradam 05 1900 (has links)
Architectural, Engineering and Construction (AEC) projects are becoming more complex in terms of client requirements, stakeholder issues, physical, budget and time constraints, and safety and environmental concerns. These constraints have spawned ad-hoc innovations in some AEC projects, without structured frameworks for their assessment, resulting in varying success for these innovations.
The primary goal of the thesis is to test an existing framework for evaluating innovative design and construction technologies for high-rise buildings by way of a case-study. The case study is a48-story structure (with an 8-level sub-grade parkade) in a downtown setting with significant constraints and challenges. Unlike most other assessment frameworks which are single-issue based (financial, cost, time or risk), a holistic method that captures a broad range of critical issues at the micro and macro levels is used to screen a number of construction innovations. The process highlights the primary difficulty in balancing stakeholder issues, technical/engineering requirements and project goals in assessing the overall feasibility and net benefits of an innovation. As a useful tool, it facilitates the engineering/technical judgment of proposed innovations and provides evidence of a sufficient trade-off between incremental 'cost and benefits' to justify a detailed evaluation and possible subsequent use of a subset of the innovations that passed successfully through a tiered first stage evaluation process.
A secondary objective is to propose appropriate quantitative models for a detailed evaluation of the screened technologies that not only seeks to quantify incremental cost and benefits (e.g. time, increased revenue, etc.) but also assess the level of certainty (in benefits and cost) of innovative construction technologies. An illustrative evaluation provides insights as to the level of modeling and analysis required to evaluate an innovative or novel strategy both at the 'activity/work package' and project levels. The quantum of data required at the pre-construction planning stage coupled with the lack of easy to apply evaluation models probably accounts for the non-prevalence of detailed quantitative evaluation of innovative construction technologies on AEC projects, especially in terms of impact at the project level and the degree of certainty with which net benefits are likely to be achieved.

Designing constraints for capacity analysis of residential floor areasLi, Jing Qiang January 2004 (has links)
This thesis focuses on the development of design constraints for use in analyzing the capacity of the residential units' floor areas in Open Building projects. Two cases are used to demonstrate the use of these constraints: a vacant office building (Kales Building) being converted to residential occupancy; a new multi-story building the lower floors of which are hotel rooms and the upper floors are residential condominium units.The thesis suggests that these constraints and the capacity analysis of residential floor areas associated with them can assist design teams, at the beginning of similar projects; provide important "added value" to clients, and contribute to the long term "sustainability" or adaptability of buildings.The first part of the thesis addresses the question of how to design a residential base building which can accommodate an optimal number and variety of fit-out unit layouts. The answer to the question links to the need for design constraints and points to their use in capacity analysis.The second part of the thesis focuses on the deduction of "constraint-designing" for Open Building residential layout. Plumbing systems, which are one of the most significant barriers to the application of Open Building, are specifically and more deeply studied in this part. A series of constraints are developed, which can generally assist in designing and analyzing floor plate capacity. . It is akin to learning to know the rules before starting a game.The third part of the thesis focuses on the demonstration of the uses of constraints in the design process of the conversion of an abandoned office building to residential uses.The last part of the thesis demonstrates the use of constraints and capacity analysis in a new multi-story condo project.In short, the paper is initially concerned with both the design concept and its application into detail levels in one of the many issues. It is a study of methods and technical rules of designing floor plan layouts when capacity analysis is the aim. / Department of Architecture

Performance-based Design of RC Coupled Wall High-rise Buildings with Viscoelastic Coupling DampersMacKay-Lyons, Renée 18 March 2013 (has links)
A new damping technology, the Viscoelastic Coupling Damper (VCD), has been developed at the University of Toronto for reinforced concrete (RC) coupled wall high-rise buildings. These dampers are introduced in place of coupling beams to provide distributed supplemental damping in all lateral modes of vibration. This thesis presents an analytical investigation of the application of VCDs in a high-rise case study building located in a region of high seismicity. A parametric study has been conducted to determine the optimal number and placement of the dampers to achieve enhanced seismic performance without compromising the wind response of the structure. Nonlinear time history analyses have been carried out in order to compare the seismic performance of a conventional coupled wall building to alternative designs incorporating VCDs. Results highlight the improved performance of VCDs over RC coupling beams at all levels of seismic hazard. A design procedure for seismic-critical buildings is proposed.

Simulating the Effects of Enclosure Retrofits on Post-War High-Rise Apartment Buildings in Cold ClimatesCharbonneau, Matthew 26 August 2011 (has links)
A large portion of the existing building stock in North America is comprised of post-World War II high-rise apartment buildings, particularly in the Greater Golden Horseshoe in Ontario. They are home to a large portion of the Canadian population. These buildings are nearly 50 years old and reaching the end of their useful lifespan. Significant deterioration has lead to life safety concerns, poor standards of living, and aesthetic degradation. They also consume a significant amount of energy resulting in contributing to Canada’s high per capita greenhouse gas emissions.
This thesis investigates the impact of various retrofit strategies on the energy consumption, durability, and occupant comfort of the towers. The building enclosure is the primary focus. The impacts were analyzed using three approaches. Whole building energy consumption was simulated by adapting a spreadsheet based Building Energy and Loads Analysis (BELA) model, originally intended for office buildings. Heat flow and temperatures across the enclosures were modeled using a two-dimensional finite element model (Therm 5.2). A single, theoretical building dubbed the, “Archetype”, was developed to define the characteristics of a “typical” tower using details extracted from four sets of drawings for towers built in Toronto during the late 1960s.
Various quantities and configurations of thermal insulation were added to the Archetype and the resulting effective thermal resistances were modeled. Adding insulation to the interior significantly reduces the effectiveness of any added thermal resistance. Insulating on the exterior allows the insulation around the balconies to reach 80% of its rated value, even without insulating the balconies.
Energy efficiency measures (EEMs) including retrofitting the walls, windows, appliances, or HVAC equipment were simulated and it was found that each on its own did not have a major impact on annual energy consumption. Packages of EEMs were created and simulated. It was found that a basic and high-performance whole building retrofit packages would save approximately 40% and 55% of the annual energy consumption, respectively, based on the Archetype.
An analysis and discussion of the enclosure retrofit impacts on freeze-thaw potential, interior surface and interstitial condensation, occupants’ thermal comfort, and passive thermal comfort was completed. An interior versus exterior enclosure retrofit comparison summary illustrated that an exterior enclosure retrofit has significant benefits relative to an interior retrofit including ease of construction, greater durability, and improved comfort. The difference in annual energy reduction between an interior and exterior enclosure retrofit was small.

A Study On Tall Buildings And Aerodynamic Modifications Against Wind ExcitationIlgin, Huseyin Emre 01 February 2006 (has links) (PDF)
The purpose of this thesis is to create basic design guidance for tall buildings and their aerodynamic modifications as a resource for architects, engineers, developers, and students. It aims to make a contribution to and strengthen particularly the architect& / #8217 / s understanding of tall building design, that requires a high level of interdisciplinary approach, by providing a broad overview of the tall building with its general concepts / to demonstrate the importance of human element as a critical component in the design of tall building by clarifying the wind forces and resulting movements which cause discomfort to building occupants and create serious serviceability issues / and to show the significance of aerodynamic modifications as an effective design approach in terms of mitigating wind excitation. In order to achieve these purposes, firstly, a comprehensive literature survey, which includes the definition, emergence and historical background, basic planning and design parameters, and lateral load considerations of tall buildings is presented. Following a structural classification of the tall buildings, wind excitation, its negative effects on occupant comfort and serviceabilty issues, and the methods to control wind excitation are studied. Finally, the significance of aerodynamic modifications against wind excitation, which include modifications of building& / #8217 / s cross-sectional shape and its corner geometry, sculptured building tops, horizontal and vertical openings through-building, are presented from the scholarship on this topic.
