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.

New Framework

Modular integrated construction (MiC) has been introduced in high-rise construction for achieving sustainable development. As high-rise MiC disruptively transforms the construction process compared with conventional construction, it is imperative to systematically understand its performance, which however has not been sufficiently reported in previous literature. Therefore, this paper aims to develop a new framework of key performance indicators (KPIs) for project stakeholders to comprehensively measure and effectively benchmark the performance of high-rise MiC projects. This framework is developed based on the concept of sustainable construction that covers social, environmental and economic aspects. Through a comprehensive literature review, expert interviews, and a focus group meeting, 32 KPIs are established in the three sustainability aspects. An eight-step process is suggested for project stakeholders to adopt these KPIs to measure MiC performance in three tiers, i.e., overall building, off-site and on-site, and modular works. A case study is then presented which demonstrates that the framework is effective in measuring the sustainability of high-rise MiC and applicable for comparing MiC with conventional practices. The framework fills the knowledge gap of performance measurement on high-rise modular construction and contributes a methodological foundation for future quantitative benchmarking of MiC sustainability.

The construction industry is characterized by high energy consumption and high carbon emissions. With growing concern about climate change, environmental protection is becoming increasingly important. In this paper, the whole construction process of prefabricated floor slab (PFS) is divided into three stages: production, transportation, and construction stages. Carbon emissions are calculated based on the life cycle assessment (LCA) method. A case study of PFS construction in Shaoxing city, China, was examined, and the calculation results were compared and evaluated with the traditional construction methods, which showed that in the production stage, carbon emissions increased due to mechanical operations during the prefabrication process. In the transportation stage, carbon emissions also increased due to the heavier prefabricated components during the transportation process. During the on-site construction stage, carbon emissions considerably decreased due to the lower hoisting frequency and less on-site pouring.

Dimensional quality plays a key role in project success for modular construction. While approaches exist for reducing rework associated with dimensional variability in traditional construction (i.e., onsite resolution), more proactive approaches must be employed during offsite production of modules. Unfortunately, the stricter dimensional quality demands in modular construction are not yet completely addressed in existing guidelines or studies. As such, contractors often must resort to use of reactive measures to reduce rework. This paper bridges this gap by demonstrating how to implement continuous benchmarking and improvement of dimensional quality by comparing as-built and nominal 3D geometric data across modular construction projects. A case study is presented for two nearly identical modular construction projects, which are carried out in succession. The first project is used to quantify and benchmark key impacts on overall dimensional quality, while strategic improvements are introduced in the second project to improve quality and reduce rework. The results of this study demonstrate how contractors can achieve adequate dimensional quality and reduce rework on successive modular construction projects.

Construction using refurbished shipping containers is a recent building system, with already many successful examples around the world. This system presents a huge potential in the field of sustainable construction provided by the recycling of used containers. This paper aims to contribute to a better knowledge of this construction system in what concerns to the structural project. The general constitution of two maritime shipping containers is presented as well as some aspects of their structural behavior. For this purpose, numerical analyses were performed using a finite elements analysis program. Normative aspects for the structural project are also presented. This paper also presents the analysis of a case study with the use of refurbished shipping containers to build a single-family house. The evaluation of the strength of the refurbished shipping containers to building actions is carried out. It is shown that such evaluation is not easy because some mechanical parameters of noncommercial steel section of the elements that compose the shipping containers are unknown. Nevertheless, this study shows the feasibility of this building system.

This study presents a state of the art and design proposal for membrane sunspaces, as alternative to conventional ones, in glass, commonly used in the functional refurbishment of old buildings. Sunspaces are passive solar systems that can be easily integrated in existing buildings. Enclosing balconies with glazing has an impact on existing building functional performance (useful area, thermal performance and acoustic improvement) and it may even postpone the renovation need of the intervened building. However, inevitably, many of old buildings are located in areas with access restrictions and other physical constraints on the movement of materials, components and equipment - that limits its construction and maintenance processes and thus demand for alternative solutions. Glass is being applied in all types of sunspaces, so architects and engineers take for granted that it has to be inevitably used. However, a major weakness of glass is its weight and cost, specially associated with installation complexity, framing systems and accessories needed. The fact that membrane requires less substructure, changes the architectural approach - giving more freedom to design options. Membrane construction technology and installation process could be a practical alternative to traditional construction methods for closing balconies in old buildings. For this research, a full-scale Membrane Alternative Sunspace prototype was implemented into an old building (taken as case study) to evaluate the real construction process aspects and compare it with the common glazed solutions. Results were examined from an environmental, economic and building technology's point of view - regarding production, construction and maintenance phases.

Single-task construction robots (STCRs) have become a popular research topic for decades. However, there is still a gap in the ubiquitous application of STCRs for onsite construction due to various reasons, such as cost concerns. Therefore, cost–benefit analysis (CBA) can be used to measure the net economic benefit of the STCRs, compared to traditional construction methods, in order to boost the implementation of STCRs. This paper presents a simple and practical framework for the economic evaluation of STCRs and conducts a case study of a cable-driven facade installation robot to verify the method. The results show that the cable-driven robot for facade installation is worth investing in in the UK, as well as in the majority of G20 countries. Furthermore, other socioenvironmental implications of STCRs and the limitations of the study are also discussed. In conclusion, the proposed method is highly adaptable and reproducible. Therefore, researchers, engineers, investors, and policy makers can easily follow and customize this method to assess the economic advantages of any STCR systems, compared to traditional construction technologies.

Prefabricated Prefinished Volumetric Construction (PPVC), also known as volumetric modular construction has recently been adopted for high-rise building construction. However, efficient ways of joining the volumetric units on site have not been well developed. The intended high productivity is thus hindered and costs of the PPVC buildings are considerably higher than traditional construction methods. Additionally, issues such as module alignment and water penetration are often exposed during the assembly of modules. Moreover, local code requirements and geographical varieties often lead to different priorities and concerns in the development of joining techniques. This paper focuses on the generic joining techniques adopted in PPVC systems. Three joining methods are presented based on the different locations where the tightening of bolted connection occurs. The methods are evaluated based on the proposed constructability criteria and structural performance. The information gathered is useful for designers and contractors to understand the priorities and issues when developing new joining techniques.
