Crane Selection

Modular construction, which involves unit production in factories and on-site work, has benefits such as low cost, high quality, and short duration, resulting from the controlled factory environment utilized. An efficient tower crane lifting plan ensures successful high-rise modular project completion. For improved efficiency, the lifting plan should minimize the reaching distance of the tower crane, because this distance directly affects the tower crane capacity, which is directly related to crane operation cost. In situations where units are lifted from trailers, the trailer-to-tower crane distance can have a significant impact on the tower crane operation efficiency. However, optimization of this distance to improve efficiency has not been sufficiently considered. This research proposes a genetic algorithm optimization model that suggests optimized tower crane and trailer locations. The case study results show that through the proposed model, the project manager can reflect the optimal location selection and optimal tower crane selection options with minimal cost.

<p>Timber is one of the few renewable materials that improves its structural properties when combined with concrete. The composite of timber and concrete increase stiffness and fire protection, unlike timber when used alone. In contrast to concrete structures, timber-concrete composite (TCC) structures reduce the carbon footprint and the specific weight of a building. At the Chair of Hybrid Structures - Structural Concrete of BTU Cottbus-Senftenberg a moment-resistant TCC joint was developed for multi-story frames, which can be used as a structural system for high-rise buildings. Facts like a modular construction, a fast assembly and a plug-in connection were aspects that shaped the development. A high rotational stiffness and load-bearing at the composite joint was also achieved using high strength beech laminated veneer lumber (LVL).</p><p>The TCC frame works on its own and in combination with other bracing systems. Initial investigations on the load-bearing behavior were carried out using numerical analysis followed by experiments on real-sized joints in further studies. First results will be presented in this paper. The developed TCC joint as part of structural systems offers a high variability and can thus contribute to tomorrow’s sustainable vertical growth of cities.</p>

Modular Buildings

Off-site construction has been increasingly employed due to its advantages, for instance, improved quality control, reduced skills labour, faster construction time, decreased material wastage and safe working environment. As the most cutting-edge off-site construction, modular buildings have been utilised for residential building, student accommodation, and hotel projects. However, because of existing and underlying constraints, the adoption of modular buildings is still relatively low. To reveal factors hindering the development of high-rise modular buildings, a comprehensive literature review, coupled with a focus group study, were conducted. A questionnaire survey inquiring about all stakeholders was implemented to quantify constraints. The results were further examined according to a real-life case study. This paper manifested that “Lack of coordination and communication among stakeholders”, “Higher cost”, “Lack of government support”, “Lack of experience and expertise”, “Lack of building codes and standards”, “Poor supply chain integration”, and “Complexity of connection” are the top barriers curbing the uptake of modular buildings. The findings should provide a valuable reference for stakeholders adopting modular buildings, whilst mitigating risks amid modular construction. Future research is expected to exploit building information modelling and design for manufacture and assembly to alleviate these existing constraints and promote the performance of modular construction as well.

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.

Floor System

With increasing demands in high-rise constructions worldwide, developing a thinner steel floor system is becoming a crucial criterion in maximizing the useable and saleable spaces within a high-rise construction. This research aims to overcome the past drawbacks and develop an innovative and economical steel floor system that can be modularized and used within a modular construction. The proposed modular steel floor system can be fabricated offsite, shipped and assembled on site. This saves the construction time and fabrication cost. In this paper, the specially designed modular floor system was optimized for both gravity and lateral loads. The seismic performances of the proposed floor system are used in a 3-story prototype building. The results show that the proposed system is highly efficient in transferring the gravity and lateral loads which can be used effectively and efficiently for modular constructions worldwide.
