Typically, sports facilities were the province of recreation or education facility planners. A category of sports activities has been isolated, however, for its cardiovascular characteristics and is the basic component of a fitness program The physiological characteristic which are of concern are those activities which contribute to the "training effect" of the heart or the ability of the heart to pump blood and oxygen to the body. The benefits of this conditioning are manifold. Longitudinal medical studies indicate that there are positive relationships across a large population for aerobic exercises or exercises which demand oxygen and decreased risk of heart attack in later life. While the correlation between exercise and good health seems merely the confirmation of good sense, it is a recent occurrence that this relationship has been quantified by corporations and utilized to increase "corporate health," through the construction of fitness facilities for employees. The intention behind this thesis is to explore the existing information about fitness centers and design a facility as the reuse of an historic building in Brooklyn, New York. / by Diane Theodora Georgopulos. / M.Arch.

They play an important role in the cognitive and formal ordering of the city. They are important to the temporal contect of the city. As the site of milestone events in many people's lives, or as symbols of these events in others' lives, church buildings are important for the collective memory. The grand scale of the church space combined with careful small scale detailing, make it a place with qualities that are rare in the daily life of most people. Because of their importance to the city opportunities and methods to reuse church buildings should be found if the buildings are abandoned by their congregations. Uses should be found that are sympathetic to the spirit and the form of the building. The forms in church architecture are powerful enough that they can survive extensive, yet sensitive, new construction to accommodate a new use and allow the place to read as a new building that was once a church. In order to allow the building to provide a temporal context to the present, when the building is given a new use it must also be given a new image. The elements of the image of a church must be analyzed to discover those which are the most powerful and how they may be changed to allow revealing juxtapositions that say, "this building was a church but is one no longer." In changing the image of the church building, care must be taken not to destroy those qualities which made attempting its reuse worthwhile. These issues are investigated in a series of case studies of reused churches. Several new issues in the redesign of church buildings were discovered through the case studies. The result is a set of observations and conclusions that are a synthesis of the real and the ideal. / by Laurie Putscher. / M.Arch.

The selection of mortar for conservation of historic and heritage buildings can be challenging. Achieving compatibility with the historic fabric, durability and efficient use of materials within a practical timeframe often requires the use of hydraulic lime-based mortars which set more rapidly than the more traditional air lime mortars. These are considered to be more compatible with historic fabric than cement-based mortars, although, due to the modern production techniques and their natural variability, a deeper knowledge of their chemical and physical properties is needed to minimise damage due to incompatibility and make the decision process easier and safer. Natural hydraulic lime (NHL) binders are currently classified under EN 459-1:2015 in three designations, NHL 2, NHL 3.5 and NHL5, with the suffix representing the minimum compressive strength (in MPa) of a standard mortar mix at 28 days. The performance of NHL binders, manufactured by burning a naturally impure limestone, can be difficult to predict due to the inherent variability of both their physical and chemical characteristics. At the same time, the tolerance values for each classification allow for binders with significantly compressive strength differences to be classified by the same designation. The main aim of this research was to study a range of NHL binders, understand and quantify the variability of their characteristics and to establish how these properties influence the performance of mortars cured under standard and simulated weather conditions. In the first stage of the project, a selection of NHL binders from different origins and distinct designation were rigorously examined through physical, chemical and mineralogical characterisation to elucidate surface area, particle size distribution, oxide composition and crystalline phase composition. The characteristics of the binders were found to vary greatly, particularly amongst binders from the same classification and distinct origins, and in one particular case even from the same origin. A change of properties over time was also identified, binders manufactured in different years could have very different properties, even though, as far as could be ascertained from the packaging, it was the same product. Starting from a selection of 11 NHLs and 1 hydrated lime, the next step involved the manufacture of mortar samples using a sand aggregate appropriate for a conservation mortar with 1:2 ratio (binder:aggregate by volume). Sufficient water was added to produce a spread by flow table of 165 ± 10 mm. These mortars were cured under standard conditions and for a smaller group of binders under simulated weather conditions. For the standard cure conditions, the properties of the binders were compared to the physical properties in terms of strength (from 7 to 1080 days), porosity, capillary water absorption, water vapour permeability and freeze-thaw resistance of mortars made with the binders. The carbonation was also studied by phenolphthalein stain after all the flexural strength tests and after 2 years by XRD. The mortars under climate simulation were studied in terms of mechanical properties (up to 360 days) and carbonation. For comparison purposes, cement-lime (1:1:6 and 1:2:9 cement:lime:aggregate volumetric ratio), lime-metakaolin (MK) (with MK addition of 5, 10 and 20% of the lime mass) and lime putty mortars were manufactured to the same workability as the NHL mortars. These were studied in terms of strength up to 360 days, porosity and water absorption by capillarity action. The strength of the studied mortars does not follow the classification of the binders, with one binder, specified as NHL 2, resulting in a stronger mortar than another binder specified as NHL 5, and one NHL 3.5 mortar surpassing all the other mortars in terms of mechanical strength. The mechanical strength was found to correlate with the hydraulic phases, alite and belite, identified within the binders. The relative long-term performance of the mortars manufactured with the different binders can therefore be predicted based on the mineral properties rather than the standard classification. Pore related properties, such as water vapour permeability and water absorption by capillarity, were found to be related to the water/binder ratio of the NHL mortars. Later in the project, using the standard cured mortars data, a model was developed to predict compressive strength based on the proportion of crystalline phases present in the mortars, the surface area and the water/binder ratio. This model, applied to the studied mortars, was found to predict, with low error, the measured performance of the mortars, meaning that the model can be used as tool to predict mortar strength. The outcomes of this thesis demonstrated that with sufficient knowledge of the underlying chemistry of NHL binders, it is possible to establish the relative performance of mortars, thus making the decision on which binder to use easier and safer for the historic fabric.

Site ORYA3, the Smith House, is located in Dayton, Oregon. The archaeological project originated because owners of this structure, listed on the National Register of Historic Places, applied for a demolition permit. The 1859 home, first occupied by two early Oregon pioneers, Andrew and Sarah Smith, was considered architecturally significant, an unique example of a territorial period home. In the years since 1859, the original building construction has not been significantly modified, nor have the grounds been looted or substantially altered. Dr. David Brauner and the Oregon State University Anthropology Department began an archaeological project at this location in anticipation of the destruction, the first time in Oregon that archaeologists have excavated the interior of a standing house. The longevity of occupation, site taphonomy, and episodes of floor repair over the years created a mixed context. The research direction for this thesis matches a statistical and descriptive analysis of a sample of the material culture with information gathered from published and unpublished archival data from the Smith house. The thesis examines cultural material found on this site and provides a basis for comparison with other similar archaeological sites. Dayton history is discussed, to provide a broad context within which to interpret the archaeological data. Occupancy background on the various residents is provided. This thesis provides a general analysis of the 10,609 artifacts and their associated provenience. This thesis is a cautionary tale for historic archaeologists working on domestic sites. Examination of material by room points out how little can really be said based only on artifact presence. On this site, oral and written histories often proved to be better sources of information than the artifacts on many subjects. / Graduation date: 1998 / Best scan available for figures.

The retention of historic structures and the information which they contain, the basic goals of historic preservation, has occurred with increasing frequency in the twenty-year period following the passage of the National Historic Preservation Act of 1966. Admittedly, the ideal scenario involves the retention and reuse of architecturally or historically important structures. However, occasionally notable buildings are found which are located upon sites earmarked for new construction or which have deteriorated to a condition which makes restoration or adaptive reuse not economically feasible. Adequate documentation prior to the destruction of such buildings not only preserves the information therein contained, but also may encourage reuse of some structures by making the owner aware of their contribution to the streetscape, to local history or to the architectural history of a community or region.Although parameters for adequate documentation exist at the national level for national landmarks, state and local standards are vague at best, leaving both the professional and the non-professional preservationist to determine the level of documentation and the amount of research required. Difficult at best for the professional, documentation in the absence of guidelines frequently proves disastrous for the non-professional.This thesis is the product of a documentation project conducted between September 1984 and October 1985 to provide "adequate documentation" for a client of the College of Architecture and Planning at Ball State University, Muncie, Indiana. Having no established guidelines or precedent to follow, and instructed to produce "adequate documentation" for 28 structures at six Indiana State Hospitals, the documentation team learned much during the fourteen-month process of producing both written and graphic documentation.The author presents this descriptive analysis of one component of the documentation process - the preparation of the 331-page written text which accompanied photographs and H.A.B.S. drawings. While each project differs, the Indiana State Hospital Project established a precedent which may be referred to By the C.A.P. when faced with similar projects in the future.

Fair face lime-based brickwork is one of the most popular types of fa?ade in early colonial buildings in Hong Kong. A good proportion of such buildings are slowly but inexorably disappearing. Since the sixties, the awareness of the general public in heritage preservation of Hong Kong started in its embryonic form, gradually evolved through the seventies and eighties, gaining momentum to active involvement in the nineties, and finally to the organized and pragmatic approach of today. In 1976, the Hong Kong Government enacted the Antiquities and Monuments Ordinance to ensure that the best examples of Hong Kong’s heritage are protected. With the establishment of the Antiquities and Monuments Office in at the same year, a number of buildings with historical and architectural values have been declared as monument or included in the list of graded heritage buildings since then and their conditions are being concerned. However, conservation principles have not been highlighted in our local heritage building maintenance practices. Perhaps, due to client’s intention, funding constrains, and/or lacking of skillful craftsmen and expert supervision, incompatible building materials and inappropriate methods have been applied on those fair face brickwork fa?ade. More and more evidence shows that such maintenance practices worsen the condition of the historic fa?ade and causing damages to the heritage. No doubt, fa?ades of those deteriorating heritage buildings are deserved proper maintenance and repair under appropriate conservation approaches. The focus of this dissertation is upon the understanding the issue of brickwork failure particularly owning to the saturation of soluble salt in brickwork attributed to various inappropriate maintenance approaches. To establish a guideline for lime-based brickwork fa?ade maintenance to ensure longevity, reduce costs and improve value. / published_or_final_version / Conservation / Master / Master of Science in Conservation
