Abstract
This book aims to consolidate, structure and articulate collective knowledge on construction project delivery, procurement and contracting, so that it can serve as a gateway to the contiguous topics of construction project delivery. In addition to supporting the education of student researchers, as well as broadening and deepening the knowledge of practitioners, the book is also intended to serve as a foundation for future education and as a reference book. Academicians can use it to benchmark and support their research and also as a textbook for an undergraduate or graduate course on the topics of project delivery, procurement and contracting.

Abstract
• CPTED principles have been applied in school neighborhood safety. • Multiple crime types had significant associations with CPTED principles. • The cleanliness of streets and visual quality of buildings can reduce crime. • Being adjacent to multi-family housing and bus stops can increase crime. • The findings add to the evidence supporting the effectiveness of CPTED initiatives. Crime prevention through environmental design (CPTED) suggests an association between micro-scale environmental conditions and crime, but little empirical research exists on the detailed street-level environmental features associated with crime near low-income and minority schools. This study focuses on the neighborhoods around 14 elementary schools serving lower income populations in Seattle, WA to assess if the distribution of crime incidences (2013–2017) is linked with the street-level environmental features that reflect CPTED principles. We used a total of 40 audit variables that were included in the four domains derived from the broken windows theory and CPTED principles: natural surveillance (e.g., number of windows, balconies, and a sense of surveillance), territoriality (e.g., crime watch signs, trees), image/maintenance (e.g., graffiti and a sense of maintenance/cleanness), and geographical juxtaposition (e.g., bus stops, presence of arterial). We found that multiple crime types had significant associations with CPTED components at the street level. Among the CPTED domains, two image/maintenance features (i.e., maintenance of streets and visual quality of buildings) and two geographical juxtaposition features (i.e., being adjacent to multi-family housing and bus stops) were consistently associated with both violent and property crime. The findings suggest that local efforts to improve maintenance of streets and visual quality of buildings and broader planning efforts to control specific land uses near schools are important to improve safety in marginalized neighborhoods near schools that tend to be more vulnerable to crime. Our research on micro-scale environmental determinants of crime can also serve as promising targets for CPTED research and initiatives. [ABSTRACT FROM AUTHOR]

Abstract
Combining technical practice with aesthetic intent, Renaissance architecture was by nature a mathematical art. Although the limitations of surviving documents hinder efforts to discern what Italian Renaissance architects knew of mathematics, where they learned it, and how they applied this knowledge, extant drawings from the period offer one means of addressing these questions. Inscribed numerals and calculations, in particular, abound in the drawings by two leading architects of early sixteenth-century Italy, Baldassarre Peruzzi and Antonio da Sangallo the Younger, suggesting that both attained a high degree of numeracy. Comparing these contemporaries is also revealing since, while each incorporated mathematics as a central element in their architectural practice, their approaches diverge in ways that point to and illuminate significant differences in their background and design methods.

Abstract
Mixed findings have been reported in previous research regarding the impact of built environment on travel behavior, i.e. statistically and practically significant effects found in a number of empirical studies and insignificant correlations shown in many other studies. It is not clear why the estimated impact is stronger or weaker in certain urban areas, and how effective a proposed land use change/policy will be in changing certain travel behavior. This knowledge gap has made it difficult for decision makers to evaluate land use plans and policies according to their impact on vehicle miles traveled (VMT), and consequently their impact on congestion mitigation, energy conservation, and pollution and green house gas emission reduction. This research has several objectives: (1) Re-examine the effects of built-environment factors on travel behavior, in particular VMT in five U.S. metropolitan areas grouped into four case study areas; (2) Develop consistent models in all case study areas with the same model specification and datasets to enable direct comparisons; (3) Identify factors such as existing land use characteristics and land use policy decision-making processes that may explain the different impacts of built environment on VMT in different urban areas; and (4) Provide a prototype tool for government agencies and decision-makers to estimate the impact of proposed land use changes on VMT. The four case study areas include Seattle, WA; Richmond-Petersburg and Norfolk-Virginia Beach, VA; Baltimore, MD; and Washington DC. Our empirical analysis employs Bayesian multilevel models with various person-level socio-economic and demographic variables and five built-environment factors including residential density, employment density, entropy (measuring level of mixed-use development), average block size (measuring transit/walking friendliness), and distance to city center (measuring decentralization and level of infill development). Our findings show that promoting compact, mixed-use, small-block and infill developments can be effective in reducing VMT per person in all four case study areas. However, the effectiveness of land use plans and policies encouraging these types of land developments is different both across case study areas and within the same case study area. We have identified several factors that potentially influence the connection between built environment shifts and VMT changes including urban area size, existing built environment characteristics, transit service coverage and quality, and land use decision-making processes.

Abstract
Embodied and operational carbon tradeoffs in building envelopes are studied. • Envelope variables include wall assemblies, WWRs, glazing and shading. • Energy decarbonization models are used to determine the 30-year operational carbon. • Results show the importance of a total carbon approach to envelope design. • Over or under insulation can result in waste of 10–150 kgCO 2 e/m2. The building envelope has a substantial influence on a building's life cycle operational and embodied carbon emissions. Window-to-wall ratios, wall assemblies, shading and glazing types, have been shown to have a significant impact on total emissions. This paper provides building designers, owners, and policy makers with actionable guidance and a prioritization framework for establishing co-optimized lifecycle carbon performance of facade assembly components in a broad spectrum of climate contexts and energy carbon intensities. A large parametric study of building envelopes is conducted using building performance simulation and cradle-to-gate embodied carbon calculations in 6 US cities. The authors derive the total carbon emissions optimization for commercial office and residential space types using standard code-reference models and open-source lifecycle data. Comparisons between optimal total carbon solutions and (i) optimal operational carbon and (ii) minimum required assemblies, show the impact of under and over investing in envelope-related efficiency measures for each climate. Results show how the relationship between embodied and operational carbon is highly localized, that optimal design variables can vary significantly. In low carbon intensity energy grids, over investment in envelope embodied carbon can exceed as 10 kgCO 2 e/m2, while under investment in high carbon intensity grids can be higher than 150 kgCO 2 e/m2.

Abstract
Henry Hobson Richardson's design for the William Watts Sherman house, in Newport, Rhode Island, has long been considered an anomaly among his projects. While its living hall plan has always been credited to Richardson, the exterior has often been thought to have been the work of Richardson's assistant, Stanford White, drawing on the published work of Richard Norman Shaw. Study of surviving sketches, drawings, and other records, along with an examination of the house itself, shows that this explanation of the Sherman house is inadequate. Not only did Richardson control both plan and massing, but he must also be credited with the design of critical front gable, which did not derive from Shaw's work. Analysis of Richardson's sketches also offers clues to Richardson's typical architectural design method and compositional approach, as well as to his specific blending of English, Continental, and especially American colonial vernacular influences in the Sherman design. These influences also provide a basis for understanding why the house became such an important source for the development of multiple themes in American domestic architecture in succeeding decades, especially the Shingle Style.

Abstract
Adler and Sullivan's Seattle Opera House project is known from a perspective drawing and three plans that were first published in Inland Architect in 1891. It has been known that the demise of the project was due to financial difficulties, but otherwise the circumstances surrounding the commission have remained obscure. This article presents new information regarding the client, the commission, and the architects. Seattle newspaper reports, surviving correspondence, and project records provide the basis for a more detailed description of the Opera House project history. In addition, correspondence from Charles H. Bebb, who was sent to Seattle for several months in 1890 as superintending architect for Adler and Sullivan, provides insight into the condition of their office before his permanent move to the city in 1893.
