The atlas compiled by these editors is a commendable effort and welcome addition to the mycology textbook sector. Up until now, the publication of medical mycology textbooks has been sparse and those that have been published are either too detailed for a resident in training or practicing physician or do not provide sufficient photographs or illustrations of the main features of the mycotic organisms. As a lecturer in mycology for the dermatology residents at my local teaching hospital and program, there are 3 key objectives of my mycology lectures: (1) to provide some type of organizational approach to mycotic organisms, (2) to provide a concise clinical history, and (3) to provide as many photographs and illustrations of mycotic organisms as possible. This atlas provides an exemplary addition to my book collection on medical mycology textbooks and sources for illustrations of mycotic organisms. The electron photomicrographs, photoplates, and line drawings of

Off-site construction has gained more attention from both academia and industry during the last few years. Modular construction is one of the most efficient off-site construction methods. In this method, different parts (components) of a building are designed and fabricated off the construction site in factories as one or more modules, and then they are assembled on site to form the final product. Studies have shown that the modular building technique is applicable to different types of buildings, including residential, commercial, educational, and medical. Environmental performance is one of the most significant dimensions leading to sustainability. Since buildings account for a substantial portion of environmental burdens, the main focus of this study is on the environmental performance of modular facilities over their life cycle. This article also presents a comprehensive critical literature review on the benefits and challenges of the modular construction method, compared to its conventional counterpart. It is concluded that, on average, modular buildings have been shown to provide a better life cycle performance, for example a building׳s energy performance, among others. Further life cycle research, considering all the dimensions of sustainable construction, is recommended in order to develop a robust picture of the sustainability of modular construction.

Life cycle performance of modular buildings: A critical review

Volumetric prefabricated building construction is growing in most developed countries; for example, in Sweden the market share of prefabricated building systems in the housing industry was more than 80%. However, in Australia only approximately 3–4% of new building constructions are prefabricated buildings in a year. A major hindrance to the growth of prefab construction in Australia is that systems are developed under commercial and confidential conditions. There are limited publicly-available research and case studies for certifiers, regulators, engineers and academia to provide independent information on the performance, advantages and disadvantages of prefabricated building systems. Independent designers and structural engineers are relying on the strength of the structural and non-structural element, as well as the connections of the prefabricated building systems. This strength is estimated from the “commercial-in-confidence” test of individual components by manufactures, and it might result in undesired outcomes in design. This paper provides an overview of available literature on structural performance, benefits, constraints and challenges of prefabricated building systems. This paper also highlights the research needed on the prefabricated building systems such as full-scale tests, numerical modelling, hybrid simulations, case studies and social and economic assessments. Being supported by sound academic research will increase the market demand for prefabricated building systems in Australia as well as in other countries.

Designing out construction waste using BIM technology: Stakeholders’ expectations for industry deployment

Methodology of Cost Parameter Estimation for Modern Methods of Construction Based on Wood

This study is aimed at the utilization of natural zeolite as a prospective type of Supplementary Cementitious Material in connection with the innovations of construction solutions through the materials. The influence of zeolite on several properties of cement-based composites is studied. Basic characteristics of input powdery materials as well as the technological parameters of zeolite tested on mortar containing 50% of cement replacement are presented. The technical parameters of concrete containing 8, 13, and 25% of cement replacement by zeolite are presented as well. The paper is valuable due to the three-year testing period. The density of the hardened concrete was found to be decreasing with increasing zeolite content. While no significant differences in compressive strength were found after 28 days, differences between individual samples were clear after the long-term period. The presence of zeolite influenced the compressive strength positively in the case of the 8% and 13% replacement, while the higher proportion of natural zeolite (25%) caused lower compressive strength after 28 days but was similar to the reference concrete after three years. A major increase in strength was detected for all samples in the long-term period. It confirms the long-term potential of zeolite for strength improvement.

Long-Term Properties of Cement-Based Composites Incorporating Natural Zeolite as a Feature of Progressive Building Material

Development of digital technologies and processes including Internet of Things (IoT) applications is central to the required transformation of the construction industry within the frame of Construction 4.0 concepts originated from the fourth industrial revolution Industry 4.0. The construction sector has vast potential to improve productivity and efficiency thanks to digitalization, innovative technologies and new construction techniques. The new tool Concremote, offered by multinational expert in solutions of formwork, uses digital sensors to measure the in-situ concrete maturity gradient and with this data it calculates early age strength. Being able to measure in real time the development of in-situ concrete maturity can reduce striking time and thus reduce cost of formwork. The aim of the case study is to demonstrate saving of formwork cost due reducing striking time through intended employment of the tool Concremote in construction of slabs. The cost of slab formwork was estimated in different variants of formwork striking times. For most variants of construction time and striking time, it was verified that the saving of the formwork cost due reducing striking time is higher than cost of the Concremote employment in the referenced construction.

Construction Cost Saving Through Adoption of IoT Applications in Concrete Works

The aim of the paper is to demonstrate the widely presented benefits of modular construction as compared with traditional construction method. A case study of family house construction by modular building method and traditional method is used to examine the structural, economic and time indicators of individual construction methods. The results are presented in tabular and graphical outputs and are compared each other in regard to different technological parts of the building. The paper provides the comparison of economic and time indicators resulting from budgets and time schedules of construction that are executed for different variants. Such comparison demonstrates exactly the benefits of modular construction. The building based on building modules consisted of steel bearing structure and enveloped by sandwich panels is adopted as the selected modular construction technology. The different variant, applied for comparison of modular and traditional construction, is represented by the building with comparable thermo-technical characteristics, constructed by traditional masonry method.

Sustainable Construction Technology Based on Building Modules

Several factors should be considered by the owner and general contractor in the process of contractorsand subcontractorsselection and evaluation. The paper reviews the recent models addressed to guide general contractors in subcontractors' selection process and in evaluation of different contractors during the execution of the project. Moreover the paper suggests the impact of different contractors' performance to the overall level of occupational health and safety culture at the sites. It deals with the factors influencing the safety performance of contractors during construction and analyses the methods for assessing the safety performance of construction contractors. The results of contractors' safety performance evaluation could be a useful tool in motivating contractors to achieve better safety outcomes or could have effect on ownersor general contractors' decision making about contractors suitability for future contracting works.
