Lightweight and Advance Precast Concrete System for Modular Building Construction
Productivity and efficiency are the critical aspects emphasised by the present Singapore construction industry, and these demands are addressed from two key approaches: construction materials and methods. These aspects involve the intensive coordination amongst various stakeholders in construction, prompting a need to collaborate and utilise highly intricate technologies such as Design for Manufacturing and Assembly (DfMA) in Advanced Precast Concrete System (APCS) and Prefabricated Pre-Finished Volumetric Construction (PPVC). DfMA is a systematic quality control method of construction that is vital to Singapore’s Construction Industry Transformation Map. PPVC system taps on the 3-dimensional modular production technology, fabricating modules off-site, and later installed on-site. However, the limitation for incorporating Concrete PPVC in Healthcare and Institutional buildings lies in the mismatch between PPVC module dimensions and the predominant design philosophy of the flat slab system. Thus, there is a need for a more flexible PPVC construction methodology to allow the construction to tap on the benefits of DfMA. The proposed Large Panel System (LPS) is used in conjunction with Concrete PPVC to overcome the rigidity in the design and construction of healthcare and institutional buildings. In the present study, a typical cast-in-situ Lightweight Concrete (LWC) building and a PPVC-LPS Hybrid LWC building are modelled and analysed using a 3D Non-linear Structural Finite Element software. Both buildings are designed based on various design limit states from the Eurocode 2 (EC2) section of Structural Lightweight Aggregate Concrete (LWAC), and their performances are compared. This paper aims to study the viability of the PPVC-LPS Hybrid LWC construction for healthcare and institutional buildings. Compared to the conventional cast-in-situ method, the innovative hybrid construction is found to be more superior due to its rapid connection method, meeting the structural integrity performance of cast-in-situ buildings.
